• the performance of projects undertaken by the non-utility businesses and the success of efforts to invest in and develop new opportunities;

• internal restructuring or other restructuring options that may be pursued;

• potential business strategies, including acquisitions or dispositions of assets or businesses, which cannot be assured to be completed or beneficial to Southern Company or its subsidiaries;

7

• the ability of counterparties of Southern Company and its subsidiaries to make payments as and when due and to perform as required;

• the ability to obtain new short- and long-term contracts with wholesale customers;

• the direct or indirect effect on the Southern Company system's business resulting from terrorist incidents and the threat of terrorist incidents, including cyber intrusion;

• interest rate fluctuations and financial market conditions and the results of financing efforts, including Southern Company's and its subsidiaries' credit ratings;

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Southern Company is a holding company that owns all of the common stock of the traditional operating companies – Alabama Power, Georgia Power, Gulf Power, and Mississippi Power – and Southern Power and other direct and indirect subsidiaries. Discussion of the results of operations is focused on the Southern Company system's primary business of electricity sales by the traditional operating companies and Southern Power. The four traditional operating companies are vertically integrated utilities providing electric service in four Southeastern states. Southern Power constructs, acquires, owns, and manages generation assets, including renewable energy projects, and sells electricity at market-based rates in the wholesale market. Southern Company's other business activities include investments in leveraged lease projects and telecommunications.

Southern Company's third quarter 2012 net income after dividends on preferred and preference stock of subsidiaries was $976 million ($1.11 per share) compared to $916 million ($1.07 per share) for the third quarter 2011. The increase for the third quarter 2012 when compared to the corresponding period in 2011 was primarily the result of a net decrease in non-fuel operating expenses, partially offset by a net decrease in retail revenues. Retail revenues in the third quarter 2012 decreased primarily due to milder weather and a decrease in customer usage, largely offset by an increase in revenues associated with the elimination of a tax-related adjustment under Alabama Power's rate structure, an increase related to retail revenue rate effects at Georgia Power, and an increase in revenues due to increases in retail base rates at Gulf Power.

Southern Company's year-to-date 2012 net income after dividends on preferred and preference stock of subsidiaries was $1.97 billion ($2.26 per share) compared to $1.94 billion ($2.27 per share) for year-to-date 2011. The net income increase for year-to-date 2012 when compared to the corresponding period in 2011 was primarily the result of a net decrease in non-fuel operating expenses, including an insurance recovery received related to the litigation settlement with MC Asset Recovery, LLC, partially offset by a net decrease in retail revenues and lower energy revenues at Southern Power. Retail revenues for year-to-date 2012 decreased primarily due to milder weather and a decrease in customer usage, largely offset by increases in revenues associated with the elimination of a tax-related adjustment under Alabama Power's rate structure, an increase related to retail revenue rate effects at Georgia Power, an increase in revenues due to increases in retail base rates at Gulf Power, and an increase in customer growth.

Retail Revenues

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(314)	(6.7)	$(863)	(7.2)

In the third quarter 2012, retail revenues were $4.38 billion compared to $4.69 billion for the corresponding period in 2011. For year-to-date 2012, retail revenues were $11.07 billion compared to $11.93 billion for the corresponding period in 2011.

Details of the change to retail revenues were as follows: 

	Third Quarter 2012					Year-to-Date 2012
	(in millions)			(% change)		(in millions)			(% change)
Retail – prior year	$	4,693				$	11,931
Estimated change in –
Rates and pricing	118			2.5		252			2.1

Retail – current year	$	4,379		(6.7	)%	$	11,068		(7.2	)%

Revenues associated with changes in rates and pricing increased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to the elimination of a tax-related adjustment under Alabama Power's rate structure that was effective with October 2011 billings and higher revenues due to increases in retail base rates at Gulf Power. Also contributing to the increase were increases in retail revenues at Georgia Power due to base tariff increases effective April 1, 2012 related to placing Plant McDonough-Atkinson Units 4 and 5 in service, the NCCR and demand-side management tariff increases effective January 1, 2012, as approved by the Georgia PSC, and for year-to-date 2012, the rate pricing effect of decreased customer usage. These increases at Georgia Power were partially offset by lower contributions from market-driven rates from commercial and industrial customers.

Revenues attributable to changes in sales decreased in the third quarter 2012 when compared to the corresponding period in 2011. For third quarter 2012, the decrease was due to a 2.1% decrease in weather-adjusted residential KWH sales and a 1.9% decrease in industrial KWH sales, while weather-adjusted commercial KWH sales remained flat. The decrease in weather-adjusted residential KWH sales for the third quarter 2012 was primarily due to a decrease in customer usage. The decrease in industrial KWH sales for the third quarter 2012 was primarily due to decreases in the chemical, paper, and textiles sectors, partially offset by increases in the non-manufacturing, transportation, and pipeline sectors. Revenues attributable to changes in sales remained relatively flat for all classes for year-to-date 2012 when compared to the corresponding period in 2011. While overall industrial KWH sales were relatively flat for year-to-date 2012, there were decreases in the chemical, paper, and textiles sectors, largely offset by increases in the non-manufacturing, transportation, and pipeline sectors.

Revenues resulting from changes in weather decreased $95 million in the third quarter 2012 and $292 million for year-to-date 2012 when compared to the corresponding periods in 2011 as a result of milder weather in 2012.

Fuel and other cost recovery revenues decreased $304 million in the third quarter 2012 and $830 million for year-to-date 2012 when compared to the corresponding periods in 2011. Electric rates for the traditional operating companies include provisions to adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these provisions, fuel revenues generally equal fuel expenses, including the energy component of purchased power costs, and do not affect net income.

Wholesale Revenues

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(60)	(10.8)	$(252)	(16.7)

Wholesale revenues consist of PPAs with investor-owned utilities and electric cooperatives, unit power sales contracts, and short-term opportunity sales. Wholesale revenues from PPAs and unit power sales contracts have both capacity and energy components. Capacity revenues reflect the recovery of fixed costs and a return on investment. Energy revenues will vary depending on fuel prices, the market prices of wholesale energy compared to the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. Short-term opportunity sales are made at market-based rates that generally provide a margin above the Southern Company system's variable cost to produce the energy.

In the third quarter 2012, wholesale revenues were $497 million compared to $557 million for the corresponding period in 2011, reflecting a $87 million decrease in energy revenues, partially offset by a $27 million increase in capacity revenues. The decrease in energy revenues was primarily related to a reduction in the average price of energy and lower energy sales mainly due to lower customer demand.

For year-to-date 2012, wholesale revenues were $1.26 billion compared to $1.51 billion for the corresponding period in 2011, reflecting a $300 million decrease in energy revenues, partially offset by a $48 million increase in capacity revenues. The decrease in energy revenues was primarily related to a reduction in the average price of energy and lower energy sales mainly due to lower customer demand.

Fuel and Purchased Power Expenses

Purchased power	(51		)	(23.7	)	(5		)	(1.1	)
Total fuel and purchased power expenses	$	(406	)			$	(1,155	)

In the third quarter 2012, total fuel and purchased power expenses were $1.72 billion compared to $2.12 billion for the corresponding period in 2011. The decrease was primarily the result of a $281 million decrease in the average cost of fuel and purchased power, a $119 million decrease in the volume of KWHs generated, and a $6 million decrease in the volume of KWHs purchased.

For year-to-date 2012, total fuel and purchased power expenses were $4.36 billion compared to $5.52 billion for the corresponding period in 2011. The decrease was primarily the result of a $997 million decrease in the average cost of fuel and purchased power and a $552 million decrease in the volume of KWHs generated, partially offset by a $394 million increase in the volume of KWHs purchased.

Fuel and purchased power energy transactions at the traditional operating companies are generally offset by energy revenues and do not have a significant impact on net income. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Retail Fuel Cost Recovery" herein for additional information. Fuel expenses incurred under Southern Power's PPAs are generally the responsibility of the counterparties and do not significantly impact net income.

Average cost of purchased power (cents per net KWH)(a)	4.98	6.29	4.32	7.06

(a) Average cost of purchased power includes fuel purchased by the electric utilities for tolling agreements where power is generated by the provider.

Fuel

In the third quarter 2012, fuel expense was $1.55 billion compared to $1.91 billion for the corresponding period in 2011. The decrease was primarily due to a 27.6% decrease in the average cost of gas per KWH generated, a higher percentage of generation from lower cost natural gas-fired resources, and lower customer demand mainly due to milder weather in 2012.

For year-to-date 2012, fuel expense was $3.91 billion compared to $5.06 billion for the corresponding period in 2011. The decrease was primarily due to a 32.2% decrease in the average cost of gas per KWH generated, a higher percentage of generation from lower cost natural gas-fired resources, and lower customer demand mainly due to milder weather in 2012.

Purchased Power

In the third quarter 2012, purchased power expense was $164 million compared to $215 million for the corresponding period in 2011. The decrease was primarily due to a 20.8% decrease in the average cost per KWH purchased.

For year-to-date 2012, purchased power expense was $455 million compared to $460 million for the corresponding period in 2011. The decrease was due to a 38.8% decrease in the average cost per KWH purchased, partially offset by a 67.4% increase in the volume of KWHs purchased as the market cost of available energy was lower than the marginal cost of generation available.

Energy purchases will vary depending on demand for energy within the Southern Company system's service territory, the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, and the availability of the Southern Company system's generation.

In the third quarter 2012, other operations and maintenance expenses were $906 million compared to $983 million for the corresponding period in 2011. The decrease was primarily the result of a $29 million decrease in transmission and distribution costs and a $19 million decrease related to scheduled outage and maintenance costs and commodity and labor costs, which were attributable to cost containment efforts to offset the effect of milder weather in 2012. Also contributing to the decrease were a $13 million decrease in administrative and general costs, a $13 million net decrease in customer accounts and sales related costs, and an $11 million decrease at Mississippi Power related to the expiration of an operating lease for Plant Daniel Units 3 and 4. The decrease was partially offset by an $11 million increase at Alabama Power related to the amortization of nuclear outage expenses.

For year-to-date 2012, other operations and maintenance expenses were $2.82 billion compared to $2.84 billion for the corresponding period in 2011. The decrease was primarily the result of a $50 million decrease related to scheduled outage and maintenance costs and commodity and labor costs and a $14 million decrease in distribution costs, which were attributable to cost containment efforts to offset the effect of milder weather in 2012. Also contributing to the decrease were a $32 million decrease at Mississippi Power related to the expiration of an operating lease for Plant Daniel Units 3 and 4 and a $7 million net decrease in customer accounts, sales, and customer service related costs. The decrease was partially offset by a $58 million increase in administrative and general costs primarily due to increases in pension costs and a $24 million increase at Alabama Power related to the amortization of nuclear outage expenses.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Southern Company's future earnings potential. The level of Southern Company's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of the Southern Company system's primary business of selling electricity. These factors include the traditional operating companies' ability to maintain a constructive regulatory environment that continues to allow for the timely recovery of prudently incurred costs during a time of increasing costs. Another major factor is the profitability of the competitive wholesale supply business. Future earnings for the electricity business in the near term will depend, in part, upon maintaining energy sales which is subject to a number of factors. These factors include weather, competition, new energy contracts with neighboring utilities and other wholesale customers, energy conservation practiced by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or decline in the service territory. In addition, the level of future earnings for the wholesale supply business also depends on numerous factors including creditworthiness of customers, total generating capacity available and related costs, future acquisitions and construction of generating facilities, and the successful remarketing of capacity as current contracts expire. Changes in economic conditions impact sales for the traditional operating companies and Southern Power, and the pace of the economic recovery remains uncertain. The timing and extent of the economic recovery will impact growth and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Southern Company in Item 7 of the Form 10-K.

Environmental Matters

Compliance costs related to federal and state environmental statutes and regulations could affect earnings if such costs cannot continue to be fully recovered in rates on a timely basis. Environmental compliance spending over the next several years may differ materially from the amounts estimated. The timing, specific requirements, and estimated costs could change as environmental statutes and regulations are adopted or modified. Further, higher costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could negatively affect results of operations, cash flows, and financial condition. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Environmental Matters" in Item 8 of the Form 10-K for additional information.

New Source Review Actions

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – New Source Review Actions" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Environmental Matters – New Source Review Actions" in Item 8 of the Form 10-K for additional information. On February 23, 2012, the EPA filed a motion in the U.S. District Court for the Northern District of Alabama seeking vacatur of the judgment and recusal of the judge in the case involving Alabama Power (including claims related to a unit co-owned by Mississippi Power). The U.S. District Court for the Northern District of Alabama has not ruled on the EPA's motion seeking vacatur of the judgment. The ultimate outcome of this matter cannot be determined at this time.

Environmental Statutes and Regulations

General

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – General" of Southern Company in Item 7 of the Form 10-K for information regarding the Southern Company system's estimated base level capital expenditures to comply with existing statutes and regulations for 2012 through 2014, as well as the Southern Company system's preliminary estimates for potential incremental environmental compliance investments associated with complying with the EPA's final Mercury and Air Toxics Standards (MATS) rule (formerly referred to as the Utility Maximum Achievable Control Technology rule) and the EPA's proposed water and coal combustion byproducts rules.

The Southern Company system is continuing to develop its compliance strategy and to assess the potential costs of complying with the MATS rule and the EPA's proposed water and coal combustion byproducts rules. As part of the development of its compliance strategy for the MATS rule, the Southern Company system has entered into agreements for the construction of baghouses to control the emissions of mercury and particulates from certain generating units. While the final MATS compliance plan is still being developed and the ultimate costs remain uncertain, the compliance decisions made in 2012 have allowed the Southern Company system to further develop its cost estimates for compliance with the MATS rule. As a result, estimated compliance costs for the MATS rule in the 2012 through 2014 period have been revised from up to $2.7 billion to approximately $1.8 billion as follows: 

	2012		2013		2014
			(in millions)
MATS rule	$	150	$	440	$	1,215

22

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In addition, the Southern Company system has further developed its estimated capital expenditures and associated timing of these expenditures to comply with the proposed water and coal combustion byproducts rules, resulting in a reduction, due primarily to timing, in estimated compliance costs for 2012 through 2014. Potential incremental environmental compliance investments to comply with the proposed water and coal combustion byproducts rules have been revised from up to $1.5 billion to approximately $500 million over the 2012 through 2014 period based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule. These potential incremental environmental compliance investments are estimated as follows: 

	2012		2013		2014
			(in millions)
Proposed water and coal combustion byproducts rules	$	10	$	85	$	405

While the Southern Company system's ultimate costs of compliance with the MATS rule and the proposed water and coal combustion byproducts rules remain uncertain, the Southern Company system estimates that compliance costs through 2021 (assuming that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) will be at the low end of the $13 billion to $18 billion range provided in the Form 10-K. Included in this amount is approximately $750 million that is also included in the 2012 through 2014 base level capital investment of the traditional operating companies described in the Form 10-K in anticipation of these rules.

The Southern Company system's ultimate compliance strategy and actual future environmental capital expenditures are dependent on development of the final MATS compliance plan and will be affected by the final requirements of new or revised environmental regulations that are promulgated; the outcome of any legal challenges to the environmental rules; the cost, availability, and existing inventory of emissions allowances; and the fuel mix of the electric utilities. Compliance costs may arise from retirement and replacement of existing units, installation of additional environmental controls, upgrades to the transmission system, and changing fuel sources for certain existing units. The ultimate outcome of these matters cannot be determined at this time.

As part of SEGCO's environmental compliance strategy, the Board of Directors of SEGCO approved adding natural gas as the primary fuel source in 2015 for its 1,000 MWs of generating capacity and the construction of the necessary natural gas pipeline. SEGCO is jointly owned by Alabama Power and Georgia Power. The capacity of SEGCO's units is sold to Alabama Power and Georgia Power through a PPA. The impact of SEGCO's ultimate compliance strategy on the PPA costs cannot be determined at this time; however, if such costs cannot continue to be recovered through retail rates, they could have a material impact on Southern Company's financial statements.

Air Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality" of Southern Company in Item 7 of the Form 10-K for additional information on the eight-hour ozone and fine particulate matter air quality standards, the MATS rule, the Cross-State Air Pollution Rule (CSAPR), and the Clean Air Visibility Rule (CAVR).

On May 21, 2012, the EPA published its final determination of nonattainment areas based on the 2008 eight-hour ozone air quality standards. The only area within the traditional operating companies' service territory designated as a nonattainment area was a 15-county area within metropolitan Atlanta. The potential impact of the revised standard and nonattainment designation will depend on further evaluation and implementation by the Georgia Environmental Protection Division and cannot be determined at this time.

23

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

On June 14, 2012, the EPA proposed a rule that would increase the stringency of the fine particulate matter national ambient air quality standards. If adopted, the proposed standards could result in the designation of new nonattainment areas within the Southern Company system's service territory. As part of a related settlement, the EPA has agreed to finalize the proposed rule by December 14, 2012. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Numerous petitions for administrative reconsideration of the MATS rule, including a petition by Southern Company and its subsidiaries, have been filed with the EPA. Challenges to the final rule have also been filed in the U.S. District Court for the District of Columbia by numerous states, environmental organizations, industry groups, and others. The impact of the MATS rule will depend on the outcome of these and any other legal challenges and, therefore, cannot be determined at this time.

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR in its entirety and directed the EPA to continue to administer the Clean Air Interstate Rule pending the EPA's development of a valid replacement. The vacatur of CSAPR creates additional uncertainty with respect to whether additional controls may be required for CAVR and best available retrofit technology compliance. On October 5, 2012, the EPA filed for review of the decision by the U.S. Court of Appeals for the District of Columbia Circuit. The ultimate outcome of this matter depends on the outcome of any legal challenges and further action by the EPA and cannot be determined at this time.

On August 29, 2012, the EPA published proposed revisions to the New Source Performance Standard (NSPS) for Stationary Combustion Turbines (CTs). If finalized, the revisions would apply the NSPS to all new, reconstructed, and modified CTs, including CTs at combined cycle units, during all periods of operation, including startup and shutdown, and alter the criteria for determining when an existing CT has been reconstructed. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Water Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Water Quality" of Southern Company in Item 7 of the Form 10-K for additional information on the proposed rules regarding certain cooling water intake structures. The EPA has entered into an amended settlement agreement to extend the deadline for issuing a final rule until June 27, 2013. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Coal Combustion Byproducts

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Coal Combustion Byproducts" of Southern Company in Item 7 of the Form 10-K for additional information. Environmental groups and other parties have filed lawsuits in the U.S. District Court for the District of Columbia seeking to require the EPA to complete its rulemaking process and issue final regulations pertaining to the regulation of coal combustion byproducts. The ultimate outcome of these matters cannot be determined at this time.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Southern Company in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

PSC Matters

Retail Fuel Cost Recovery

The traditional operating companies each have established fuel cost recovery rates approved by their respective state PSCs. The traditional operating companies have experienced lower pricing for natural gas resulting in an increase in natural gas generation and a decrease in coal generation, which is currently more costly. The lower cost of natural gas has resulted in total over recovered fuel costs at Alabama Power, Georgia Power, Gulf Power, and Mississippi Power included in Southern Company's Condensed Balance Sheet herein of approximately $282 million at September 30, 2012. At December 31, 2011, total under recovered fuel costs at Alabama Power and Georgia Power included in Southern Company's Condensed Balance Sheet herein were approximately $169 million, and Gulf Power and Mississippi Power had a total over recovered fuel balance included in Southern Company's Condensed Balance Sheet herein of approximately $52 million. Fuel cost recovery revenues are adjusted for differences in actual recoverable fuel costs and amounts billed in current regulated rates. Accordingly, changes in the billing factor will not have a significant effect on Southern Company's revenues or net income, but will affect annual cash flow. The traditional operating companies continuously monitor their under or over recovered fuel cost balances.

On June 21, 2012, the Georgia PSC approved a decrease in Georgia Power's fuel cost recovery rates of 19%, which reduced annual billings by $567 million effective June 1, 2012. The decrease in fuel costs resulted from lower natural gas prices as a result of increased natural gas supplies.

As of September 30, 2012, Georgia Power's fuel cost over recovery balance totaled $199 million. This balance is slightly below the $200 million required to automatically trigger the Georgia PSC's approved IFR adjustment mechanism. On November 1, 2012, Georgia Power filed a request with the Georgia PSC to voluntarily trigger the IFR early and reduce fuel cost recovery rates effective January 1, 2013. The requested reduction would reduce annual billings by approximately $122 million. In accordance with the IFR process, the Georgia PSC will have 30 days to consider Georgia Power's request. The ultimate outcome of this matter cannot be determined at this time.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Fuel Cost Recovery" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Alabama Power – Fuel Cost Recovery" and "Retail Regulatory Matters – Georgia Power – Fuel Cost Recovery" in Item 8 of the Form 10-K for additional information.

Alabama Power's under recovered Rate CNP balance as of September 30, 2012 was $14 million as compared to $6 million at December 31, 2011. Alabama Power's under recovered Rate CNP Environmental balance as of September 30, 2012 was $12 million as compared to $11 million at December 31, 2011. These under recovered balances at September 30, 2012 are included in deferred under recovered regulatory clause revenues on Southern Company's Condensed Balance Sheet herein. For Rate CNP, this classification is based on an estimate, which includes such factors as purchased power capacity and energy demand. For Rate CNP Environmental, this classification is based on an estimate, which includes such factors as costs to comply with environmental mandates and energy demand. A change in any of these factors could have a material impact on the timing of any recovery of the under recovered retail costs.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Southern Company in Item 7 of the Form 10-K for additional information. On September 17, 2012, the Alabama PSC approved and certificated the remaining PPA for the purchase of approximately 200 MWs of the approximately 400 MWs of energy from wind-powered generating facilities and all associated environmental attributes, including renewable energy credits. The terms of this PPA and the previously approved and certificated PPA permit Alabama Power to use the energy and retire the associated environmental attributes in service of its customers or to sell environmental attributes, separately or bundled with energy, to third parties.

Natural Disaster Cost Recovery

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Alabama Power – Natural Disaster Reserve" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Alabama Power – Natural Disaster Reserve" in Item 8 of the Form 10-K for additional information regarding natural disaster cost recovery. At September 30, 2012, the NDR had an accumulated balance of $102 million as compared to $110 million at December 31, 2011, which are included in Southern Company's Condensed Balance Sheets herein under other regulatory liabilities, deferred. The accruals are reflected as operations and maintenance expenses in Southern Company's Condensed Statement of Income herein.

Compliance and Pension Cost Accounting Order

On November 6, 2012, the Alabama PSC approved an accounting order for certain compliance-related operations and maintenance expenditures for the years 2013 through 2017, as well as the incremental increase in operations expense related to pension cost for 2013. Under the accounting order, expenses from January 2013 through December 2017 related to compliance with standards addressing Critical Infrastructure Protection issued by the North American Electric Reliability Corporation and cyber security requirements issued by the NRC will be deferred to a regulatory asset account and amortized over a three-year period beginning in January 2015. Expenses from January 2013 through December 2017 related to compliance with NRC guidance addressing the readiness at nuclear facilities within the U.S., as prompted by the earthquake and tsunami that struck Japan in 2011, also will be deferred as a regulatory asset and recovered over the same amortization period. The compliance-related expenses to be afforded regulatory asset treatment over the five-year period are currently estimated to be approximately $43 million. See "Other Matters" herein for information regarding the NRC's guidance issued as a result of the earthquake and tsunami that struck Japan in 2011. In addition, the accounting order authorizes Alabama Power

to defer an incremental increase in its pension cost for 2013. The increased pension cost is estimated to be approximately $17 million. During 2013, the actual incremental increase will be deferred to a regulatory asset account and will be amortized over a three-year period beginning in January 2015. Pursuant to the accounting order, Alabama Power has the ability to accelerate the amortization of the regulatory assets.

Alabama Power expects that the accounting order and other cost containment measures will preclude a need for a rate adjustment under Rate RSE.

Georgia Power

Rate Plans

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Georgia Power – Rate Plans" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Georgia Power – Rate Plans" in Item 8 of the Form 10-K for additional information on Georgia Power's 2010 ARP.

In accordance with the terms of the 2010 ARP, on November 1, 2012, Georgia Power filed the following tariff adjustments with the Georgia PSC to become effective on January 1, 2013:

• Increase the DSM tariffs by approximately $16 million;

• Increase the traditional base tariffs by approximately $58 million to recover the revenue requirements for Plant McDonough-Atkinson Units 4, 5, and 6 for the period through December 31, 2013, which also reflects a separate settlement agreement associated with the June 30, 2011 quarterly construction monitoring report for Plant McDonough-Atkinson (see Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Georgia Power – Other Construction" in Item 8 of the Form 10-K for additional information); and

• Increase the MFF tariff, consistent with the adjustments above, as well as those related to the IFR and NCCR tariff adjustments described under "Retail Fuel Cost Recovery" and Note B to the Condensed Financial Statements under "Retail Regulatory Matters – Georgia Power – Nuclear Construction" herein.

2011 Integrated Resource Plan Update

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality," "– Water Quality," and "– Coal Combustion Byproducts" of Southern Company in Item 7 and Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Georgia Power – Rate Plans" and "– 2011 Integrated Resource Plan Update" in Item 8 of the Form 10-K for additional information regarding proposed and final EPA rules and regulations, including the MATS rule for coal- and oil-fired electric utility steam generating units, revisions to effluent guidelines for steam electric power plants, and additional regulation of coal combustion byproducts; the State of Georgia's Multi-Pollutant Rule; Georgia Power's analysis of the potential costs and benefits of installing the required controls on its fossil generating units in light of these regulations; the 2010 ARP; and the 2011 IRP Update.

On March 20, 2012, the Georgia PSC approved Georgia Power's request to decertify and retire two coal-fired generation units at Plant Branch as of October 31, 2013 and December 31, 2013 and an oil-fired unit at Plant Mitchell as of March 26, 2012, which was included in Georgia Power's 2011 IRP Update. The Georgia PSC also approved three PPAs totaling 998 MWs with Southern Power for capacity and energy that will commence in 2015 and end in 2030. The PPAs remain subject to FERC approval. The ultimate outcome of this matter cannot be determined at this time.

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013), which will have a positive impact on the future cash flows of Southern Company through 2013. Due to the significant amount of estimated bonus depreciation for 2012, a portion of Southern Company's tax credit utilization will be deferred. Consequently, Southern Company's positive cash flow benefit is estimated to be between $775 million and $860 million in 2012.

Construction Program

The subsidiary companies of Southern Company are engaged in continuous construction programs to accommodate existing and estimated future loads on their respective systems. The Southern Company system intends to continue its strategy of developing and constructing new generating facilities, including the ongoing construction of natural gas and solar units at Southern Power, Plant Vogtle Units 3 and 4 at Georgia Power, and the Kemper IGCC at Mississippi Power, as well as adding or changing fuel sources for certain existing units, adding environmental control equipment, and expanding the transmission and distribution systems. For the traditional operating companies, major generation construction projects are subject to state PSC approvals in order to be included in retail rates. While Southern Power generally constructs and acquires generation assets covered by long-term PPAs, any uncontracted capacity could negatively affect future earnings. See Note 7 to the financial statements of Southern Company under "Construction Program" in Item 8 of the Form 10-K for estimated construction expenditures for the next three years. In addition, see Note 3 to the financial statements of Southern Company under "Retail Regulatory Matters – Georgia Power – Nuclear Construction," "Retail Regulatory Matters – Georgia Power – Other Construction," and "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K and Note (B) to the Condensed Financial Statements under "Retail Regulatory Matters – Georgia Power – Nuclear Construction" and "Integrated Coal Gasification Combined Cycle" herein for additional information.

Investments in Leveraged Leases

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Investments in Leveraged Leases" of Southern Company in Item 7 and Note 1 to the financial statements of Southern Company under "Leveraged Leases" in Item 8 of the Form 10-K for additional information.

The recent financial and operational performance of one of Southern Company's lessees and the associated generation assets has raised potential concerns on the part of Southern Company as to the credit quality of the lessee and the residual value of the assets. Current projections indicate significant uncertainty as to whether the lessee will be able to pay the December 2012 semi-annual rent payment in full. Southern Company continues to be engaged in discussions with the lessee and the holders of the project's nonrecourse debt to restructure the debt payments and the related rental payments to allow additional capital investment in the project to be made to improve the operation of the generation assets and the financial viability of the lease transaction. Southern Company continues to believe there is a reasonable possibility that it will be able to reach an agreement with the lessee and the debtholders to restructure the project prior to the end of 2012. However, due to continued poor performance of the generation assets and the uncertainties surrounding the receipt of the December 2012 semi-annual rent payment and its ability to successfully restructure the project, Southern Company has placed the lease on nonaccrual status whereby,

effective July 2012, income associated with this investment is not recognized in the financial statements. If the attempts at restructuring the project are unsuccessful and the project is ultimately abandoned, the potential impairment loss that would be incurred is approximately $90 million on an after-tax basis. If the restructuring is successfully completed prior to the end of 2012, Southern Company will be required to record a reduction in leveraged lease income of up to approximately $20 million in the fourth quarter 2012. The ultimate outcome of this matter cannot be determined at this time.

Other Matters

Southern Company and its subsidiaries are involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Southern Company and its subsidiaries are subject to certain claims and legal actions arising in the ordinary course of business. The business activities of Southern Company's subsidiaries are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Southern Company and its subsidiaries cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Southern Company in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Southern Company's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Other Matters" of Southern Company in Item 7 of the Form 10-K for additional information regarding the earthquake and tsunami that struck Japan in March 2011. On March 12, 2012, the NRC issued three orders and a request for information based on the NRC task force report recommendations that included, among other items, additional mitigation strategies for beyond-design-basis events, enhanced spent fuel pool instrumentation capabilities, hardened vents for certain classes of containment structures, including the one in use at Plant Hatch, site specific evaluations for seismic and flooding hazards, and various plant evaluations to ensure adequate coping capabilities during station blackout and other conditions. On August 29, 2012, the NRC staff issued the final interim staff guidance document, which offers acceptable approaches to meeting the requirements of the NRC's orders before the December 31, 2016 compliance deadline. The interim staff guidance is not mandatory, but licensees would be required to obtain NRC approval for taking an approach other than as outlined in the interim staff guidance. The final form and the resulting impact of any changes to safety requirements for nuclear reactors will be dependent on further review and action by the NRC and cannot be determined at this time. See RISK FACTORS of Southern Company in Item 1A of the Form 10-K for a discussion of certain risks associated with the licensing, construction, and operation of nuclear generating units, including potential impacts that could result from a major incident at a nuclear facility anywhere in the world. The ultimate outcome of these events cannot be determined at this time.

See "PSC Matters – Alabama Power – Compliance and Pension Cost Accounting Order" herein for additional information on Alabama Power's PSC approved accounting order, which allows the deferral of certain compliance-related operations and maintenance expenditures related to compliance with the NRC guidance.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Southern Company prepares its consolidated financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Southern Company in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Southern Company's results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Southern Company in Item 7 of the Form 10-K for a complete discussion of Southern Company's critical accounting policies and estimates related to Electric Utility Regulation, Contingent Obligations, Unbilled Revenues, and Pension and Other Postretirement Benefits.

Alabama Power and Georgia Power are now using automated meter readings to measure unbilled KWH sales for energy delivered through month end. Increased usage of actual data to compute unbilled revenues reduces the impact that estimates could have on Southern Company's results of operations; therefore, Southern Company no longer considers unbilled revenues a critical accounting estimate.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" of Southern Company in Item 7 of the Form 10-K for additional information. Southern Company's financial condition remained stable at September 30, 2012. Southern Company intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities," and "Capital Requirements and Contractual Obligations" herein for additional information.

Net cash provided from operating activities totaled $4.0 billion for the first nine months of 2012, a decrease of $554 million from the corresponding period in 2011. The decrease in net cash provided from operating activities was primarily due to an increase in fossil fuel stock as a result of milder weather in the first nine months of 2012 and lower natural gas prices and a decrease in accrued taxes due to the timing of tax payments. Net cash used for investing activities totaled $3.8 billion for the first nine months of 2012 primarily due to property additions to utility plant. Net cash used for financing activities totaled $345 million for the first nine months of 2012. This was primarily due to redemptions of long-term debt, the repurchase of common stock, and payments of common stock dividends, offset by issuances of long-term debt. Fluctuations in cash flow from financing activities vary from year to year based on capital needs and the maturity or redemption of securities.

Significant balance sheet changes for the first nine months of 2012 include an increase of $2.3 billion in total property, plant, and equipment for the construction of generation, transmission, and distribution facilities. Other significant changes include an increase in deferred income taxes of $863 million due to bonus depreciation and an increase in equity of $1.1 billion.

The market price of Southern Company's common stock at the end of the third quarter 2012 was $46.09 per share (based on the closing price as reported on the New York Stock Exchange) and the book value was $21.32 per share, representing a market-to-book ratio of 216%, compared to $46.29, $20.32, and 228%, respectively, at the end of 2011. The dividend for the third quarter 2012 was $0.49 per share compared to $0.4725 per share in the third quarter 2011.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Southern Company in Item 7 of the Form 10-K for a description of Southern Company's capital requirements for the construction programs of the Southern Company system, including estimated capital expenditures to comply with existing environmental regulations, and other funding requirements associated with scheduled maturities of long-term debt, as well as the related interest, preferred and preference stock dividends, leases, trust funding requirements, other purchase commitments, unrecognized tax benefits and interest, and derivative obligations. Approximately $2.4 billion will be required through September 30, 2013 to fund maturities and announced redemptions of long-term debt.

See FUTURE EARNINGS POTENTIAL – "Environmental Statutes and Regulations – General" herein for a description of the Southern Company system's estimated capital expenditures to comply with the MATS rule and proposed water and coal combustion byproducts rules.

The construction programs are subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; changes in environmental statutes and regulations; the outcome of any legal challenges to the environmental rules; changes in generating plants, including unit retirements and replacements and adding or changing fuel sources at existing units, to meet new regulatory requirements; changes in FERC rules and regulations; PSC approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; storm impacts; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.

Sources of Capital

Southern Company intends to meet its future capital needs through internal cash flow and external security issuances. Equity capital can be provided from any combination of Southern Company's stock plans, private placements, or public offerings. The amount and timing of additional equity capital to be raised will be contingent on Southern Company's investment opportunities.

Except as described below with respect to potential DOE loan guarantees, the traditional operating companies and Southern Power plan to obtain the funds required for construction and other purposes from sources similar to those used in the past, which were primarily from operating cash flows, security issuances, term loans, short-term borrowings, and equity contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend upon prevailing market conditions, regulatory approval, and other factors. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Southern Company in Item 7 of the Form 10-K for additional information.

In June 2010, Georgia Power reached an agreement with the DOE to accept terms for a conditional commitment for federal loan guarantees that would apply to future Georgia Power borrowings related to the construction of Plant Vogtle Units 3 and 4. Any borrowings guaranteed by the DOE would be full recourse to Georgia Power and secured by a first priority lien on Georgia Power's 45.7% undivided ownership interest in Plant Vogtle Units 3 and 4. Total guaranteed borrowings would not exceed the lesser of 70% of eligible project costs, or approximately $3.46 billion, and are expected to be funded by the Federal Financing Bank. Final approval and issuance of loan guarantees by the DOE are subject to negotiation of definitive agreements, completion of due diligence by the DOE, receipt of any necessary regulatory approvals, and satisfaction of other conditions. In the event that the DOE does not issue a loan guarantee or Georgia Power determines that the final terms and conditions of the loan guarantee by the DOE are not in the best interest of its customers, Georgia Power expects to finance the construction of Plant Vogtle Units 3 and 4 through traditional capital markets financings. There can be no assurance that the DOE will issue loan guarantees for Georgia Power.

31

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In addition, Mississippi Power has applied to the DOE for federal loan guarantees to finance a portion of the eligible construction costs of the Kemper IGCC. Mississippi Power is in advanced due diligence with the DOE. There can be no assurance that the DOE will issue federal loan guarantees for Mississippi Power. In the event that the DOE does not issue a conditional commitment or a final definitive loan guarantee, Mississippi Power expects to finance the construction of the Kemper IGCC through traditional capital markets financings. Mississippi Power also received DOE Clean Coal Power Initiative Round 2 (CCPI2) grant funds of $245 million that were used for the construction of the Kemper IGCC. An additional $25 million in CCPI2 grant funds is expected to be received for the initial operation of the Kemper IGCC.

Southern Company's current liabilities frequently exceed current assets because of the continued use of short-term debt as a funding source to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate significantly due to the seasonality of the business of the Southern Company system. To meet short-term cash needs and contingencies, Southern Company has substantial cash flow from operating activities and access to capital markets, including commercial paper programs which are backed by bank credit facilities.

At September 30, 2012, Southern Company and its subsidiaries had approximately $1.3 billion of cash and cash equivalents. Committed credit arrangements with banks at September 30, 2012, including expiration dates, were as follows:

See Note 6 to the financial statements of Southern Company under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Most of these arrangements contain covenants that limit debt levels and typically contain cross default provisions that are restricted only to the indebtedness of the individual company. Southern Company and its subsidiaries are currently in compliance with all such covenants.

A portion of the unused credit with banks is allocated to provide liquidity support to the traditional operating companies' variable rate pollution control revenue bonds and commercial paper programs. The amount of variable rate pollution control revenue bonds outstanding requiring liquidity support as of September 30, 2012 was approximately $1.8 billion.

The traditional operating companies may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell commercial paper at the request and for the benefit of each of the traditional operating companies.

Credit Rating Risk

Southern Company does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change of certain subsidiaries to BBB and Baa2, or BBB- and/or Baa3 or below. These contracts are for physical electricity purchases and sales, fuel purchases, fuel transportation and storage, emissions allowances, energy price risk management, and construction of new generation. The maximum potential collateral requirements under these contracts at September 30, 2012 were as follows:

Credit Ratings	Maximum Potential   Collateral Requirements
	(in millions)
At BBB and Baa2	$	9
At BBB- and/or Baa3	635
Below BBB- and/or Baa3	2,583

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the sale price for the pending sale of an undivided interest in the Kemper IGCC. Until the acquisition is closed, the deposit bears interest at Mississippi Power's AFUDC rate adjusted for income taxes, which was 9.967% per annum at September 30, 2012, and is refundable to SMEPA upon termination of the asset purchase agreement related to such purchase, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies.

Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, any credit rating downgrade could impact Southern Company's ability to access capital markets, particularly the short-term debt market.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Market Price Risk

Southern Company is exposed to market risks, primarily commodity price risk and interest rate risk. Southern Company may also occasionally have limited exposure to foreign currency exchange rates. To manage the volatility attributable to these exposures, Southern Company nets the exposures, where possible, to take advantage of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to Southern Company's policies in areas such as counterparty exposure and risk management practices. Southern Company's policy is that derivatives are to be used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress testing, and sensitivity analysis.

Due to cost-based rate regulation and other various cost recovery mechanisms, the traditional operating companies continue to have limited exposure to market volatility in interest rates, foreign currency, commodity fuel prices, and prices of electricity. In addition, Southern Power's exposure to market volatility in commodity fuel prices and prices of electricity is limited because its long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, Southern Power has been and may continue to be exposed to market volatility in energy-related commodity prices as a result of sales of uncontracted generating capacity. To mitigate residual risks relative to movements in electricity prices, the traditional operating companies enter into physical fixed-price contracts for the purchase and sale of electricity through the wholesale electricity market and, to a lesser extent, financial hedge contracts for natural gas purchases. The traditional operating companies continue to manage fuel-hedging programs implemented per the guidelines of their respective state PSCs. Southern Company had no material change in market risk exposure for the third quarter 2012 when compared with the December 31, 2011 reporting period.

The changes in fair value of energy-related derivative contracts, the majority of which are composed of regulatory hedges, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(170	)	$	(231	)
Contracts realized or settled	56			184
Current period changes(a)	51			(16		)
Contracts outstanding at the end of the period, assets (liabilities), net	$	(63	)	$	(63	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The changes in the fair value positions of the energy-related derivative contracts, which are substantially all attributable to both the volume and the price of natural gas, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes		Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Natural gas swaps	$	83	$	142
Natural gas options	24		27
Other energy-related derivatives	—		(1		)
Total changes	$	107	$	168

The net hedge volumes of energy-related derivative contracts were as follows:

	September 30, 2012	June 30, 2012	December 31, 2011
	mmBtu Volume
	(in millions)
Commodity – Natural gas swaps	158	141	123
Commodity – Natural gas options	111	101	66
Total hedge volume	269	242	189

The weighted average swap contract cost above market prices was approximately $0.33 per mmBtu as of September 30, 2012, $0.95 per mmBtu as of June 30, 2012, and $1.51 per mmBtu as of December 31, 2011. The change in option premiums is primarily attributable to the volatility of the market and the underlying change in the natural gas price. The majority of the natural gas hedge gains and losses are recovered through the traditional operating companies' fuel cost recovery clauses.

The net fair value of energy-related derivative contracts by hedge designation was reflected in the financial statements as follows:

Asset (Liability) Derivatives	September 30, 2012			December 31, 2011
	(in millions)
Regulatory hedges	$	(63	)	$	(221	)
Cash flow hedges	(1		)	(1		)
Not designated	1			(9		)
Total fair value	$	(63	)	$	(231	)

Energy-related derivative contracts which are designated as regulatory hedges relate to the traditional operating companies' fuel-hedging programs, where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through the fuel cost recovery clauses. Gains and losses on energy-related derivatives that are designated as cash flow hedges are mainly used by Southern Power to hedge anticipated purchases and sales and are initially deferred in OCI before being recognized in income in the same period as the hedged transaction. Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

Total net unrealized pre-tax gains recognized in income for the three and nine months ended September 30, 2012 were $5 million and $9 million, respectively, and were not material for the corresponding periods in 2011.

THE SOUTHERN COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Southern Company uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows:

	September 30, 2012 Fair Value Measurements

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Southern Company. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Southern Company and its subsidiaries and their derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Southern Company does not expect the impact of these rules to be material.

For additional information, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" of Southern Company in Item 7 and Note 1 under "Financial Instruments" and Note 11 to the financial statements of Southern Company in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein.

Financing Activities

During the first nine months of 2012, Southern Company issued approximately 11.6 million shares of common stock for $381 million through employee and director stock plans. Since mid-2011, Southern Company has issued additional equity only through its employee and director stock plans. In July 2012, Southern Company announced a program to repurchase shares to partially offset the incremental shares issued under its employee and director stock plans. Under this program, approximately 2.6 million shares have been repurchased through September 30, 2012 at a total cost of $117 million. Pursuant to Board approval, Southern Company may repurchase shares through open market purchases or privately negotiated transactions, in accordance with applicable securities laws.

In addition, Southern Company is not currently issuing shares of common stock through the Southern Investment Plan or its employee savings plan. All sales under the Southern Investment Plan and the employee savings plan are currently being funded with shares acquired on the open market by the independent plan administrators.

Southern Company's subsidiaries used the proceeds of the debt issuances shown in the table above for the redemptions and maturities shown in the table above, to repay short-term indebtedness, and for general corporate purposes, including their respective continuous construction programs.

On January 17, 2012, Southern Company's $500 million aggregate principal amount of Series 2007A 5.30% Senior Notes matured.

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the sale price for the pending sale of an undivided interest in the Kemper IGCC. Until the acquisition is closed, the deposit bears interest at Mississippi Power's AFUDC rate adjusted for income taxes, which was 9.967% per annum at September 30, 2012, and is refundable to SMEPA upon termination of the asset purchase agreement related to such purchase, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies.

In August 2012, the Mississippi Business Finance Corporation entered into an agreement to issue up to $42.5 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012A (Mississippi Power Company Project), up to $21.25 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012B (Mississippi Power Company Project), and up to $21.25 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012C (Mississippi Power Company Project) for the benefit of Mississippi Power. As reflected in the table above, in August 2012, the Mississippi Business Finance Corporation issued $4.36 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds (Mississippi Power Company Project), Series 2012B and $21.25 million aggregate principal amount of Revenue Bonds (Mississippi Power Company Project), Series 2012C for the benefit of Mississippi Power. The proceeds were  used to reimburse Mississippi Power for the cost of the acquisition, construction, equipping, installation, and improvement of certain equipment and facilities for the lignite mining facility related to the Kemper IGCC. Any future issuances of these bonds will be used for this same purpose.

Subsequent to September 30, 2012, Alabama Power issued $400 million aggregate principal amount of Series 2012B 0.550% Senior Notes due October 15, 2015. The proceeds were used to redeem, in October 2012, $200 million aggregate principal amount of Series 2007C 6.00% Senior Insured Monthly Notes due October 15, 2037 and for general corporate purposes, including Alabama Power's continuous construction program.

Subsequent to September 30, 2012, Georgia Power announced the redemption that will occur in December 2012 of $100 million aggregate principal amount of its Series 2007F 6.05% Senior Monthly Notes due December 1, 2038.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Alabama Power operates as a vertically integrated utility providing electricity to retail and wholesale customers within its traditional service territory located within the State of Alabama in addition to wholesale customers in the Southeast. Many factors affect the opportunities, challenges, and risks of Alabama Power's business of selling electricity. These factors include the ability to maintain a constructive regulatory environment, to maintain and grow energy sales given economic conditions, and to effectively manage and secure timely recovery of costs. These costs include those related to projected long-term demand growth, increasingly stringent environmental standards, fuel, capital expenditures, and restoration following major storms. Appropriately balancing required costs and capital expenditures with customer prices will continue to challenge Alabama Power for the foreseeable future.

Alabama Power continues to focus on several key performance indicators. These indicators include customer satisfaction, plant availability, system reliability, and net income after dividends on preferred and preference stock. For additional information on these indicators, see MANAGEMENT'S DISCUSSION AND ANALYSIS – OVERVIEW – "Key Performance Indicators" of Alabama Power in Item 7 of the Form 10-K.

RESULTS OF OPERATIONS

Net Income

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$16	6.1	$(15)	(2.5)

Alabama Power's net income after dividends on preferred and preference stock for the third quarter 2012 was $280 million compared to $264 million for the corresponding period in 2011. The increase for the third quarter 2012 when compared to the corresponding period in 2011 was related to an increase in revenues associated with the elimination of a tax-related adjustment under Alabama Power's rate structure, increases in industrial energy sales, and decreases in other operations and maintenance expenses, partially offset by decreases in weather-related revenues due to milder weather in the third quarter 2012 when compared to the corresponding period in 2011.

Alabama Power's net income after dividends on preferred and preference stock for year-to-date 2012 was $591 million compared to $606 million for the corresponding period in 2011. The decrease for year-to-date 2012 when compared to the corresponding period in 2011 was related to decreases in weather-related revenues due to milder weather, increases in other operations and maintenance expenses, and a decrease in AFUDC equity in 2012. These decreases were partially offset by increases in revenues associated with the elimination of a tax-related adjustment under Alabama Power's rate structure and increases in energy sales. See BUSINESS – "Rate Matters – Rate Structure and Cost Recovery Plans" of Alabama Power in Item 1 and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Retail Rate Adjustments" of Alabama Power in Item 7 of the Form 10-K for information regarding the rate structure of Alabama Power.

In the third quarter 2012, retail revenues were $1.48 billion compared to $1.49 billion for the corresponding period in 2011. For year-to-date 2012, retail revenues were $3.82 billion compared to $3.86 billion for the corresponding period in 2011.

Details of the change to retail revenues were as follows:

	Third Quarter 2012					Year-to-Date 2012

Retail – current year	$	1,476		(0.9	)%	$	3,822		(1.0	)%

Revenues associated with changes in rates and pricing increased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to the elimination of a tax-related adjustment under Alabama Power's rate structure that was effective with October 2011 billings, slightly offset by decreased revenues associated with Rate Certificated New Plant Environmental (Rate CNP Environmental).

Revenues attributable to changes in sales increased in the third quarter 2012 when compared to the corresponding period in 2011. Industrial KWH energy sales increased 0.3% due to an increase in usage resulting from changes in production levels primarily in the pipelines, automotive and plastics, and stone, clay, and glass sectors, offset by decreases in the primary metals, forest products, and textiles sectors. The changes in weather-adjusted residential and commercial KWH energy sales were not material.

Revenues attributable to changes in sales increased year-to-date 2012 when compared to the corresponding period in 2011. Weather-adjusted residential and commercial KWH energy sales increased 2.1% and 1.0%, respectively, as a result of increases in usage. Industrial KWH energy sales increased 1.9% due to an increase in usage resulting from changes in production levels primarily in the primary metals, pipelines, automotive and plastics, and forest products sectors, partially offset by decreases in the textiles, stone, clay, and glass, and water and sewer sectors.

Revenues resulting from changes in weather decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011. Alabama Power's service territory experienced milder weather conditions in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011. The resulting decreases for the third quarter 2012 were 2.9% and 1.7% for residential and commercial sales revenue, respectively. The resulting decreases for year-to-date 2012 were 5.4% and 1.9% for residential and commercial sales revenue, respectively.

Fuel and other cost recovery revenues decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to lower fuel costs associated with decreased KWH generation and lower average cost per KWH generated due to lower natural gas prices. Electric rates include provisions to recognize the full recovery of fuel costs, purchased power costs, PPAs certificated by the Alabama PSC, and costs associated with the NDR. Under these provisions, fuel and other cost recovery revenues generally equal fuel and other cost recovery expenses and do not affect net income.

Wholesale Revenues - Non-Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(1)	(1.3)	$(8)	(3.7)

Wholesale revenues from sales to non-affiliates will vary depending on the market prices of available wholesale energy compared to the cost of Alabama Power's and the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income.

In the third quarter 2012, the decrease in wholesale revenues from non-affiliates was not material. For year-to-date 2012, wholesale revenues from non-affiliates were $210 million compared to $218 million for the corresponding period in 2011. The decrease was primarily due to a 2.3% decrease in KWH sales and a 1.3% decrease in the price of energy.

(change in millions)	(% change)	(change in millions)	(% change)
$(21)	(40.4)	$(151)	(74.8)

Wholesale revenues from sales to affiliated companies within the Southern Company system will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since this energy is generally sold at marginal cost and energy purchases are generally offset by energy revenues through Alabama Power's energy cost recovery clauses.

In the third quarter 2012, wholesale revenues from affiliates were $31 million compared to $52 million for the corresponding period in 2011. The decrease was primarily due to a 27.0% decrease in KWH sales and a 19.2% decrease in the price of energy.

For year-to-date 2012, wholesale revenues from affiliates were $51 million compared to $202 million for the corresponding period in 2011. The decrease was primarily due to a 70.0% decrease in KWH sales and a 16.4% decrease in the price of energy.

In the third quarter 2012, total fuel and purchased power expenses were $541 million compared to $595 million for the corresponding period in 2011. The decrease was primarily due to a $21 million decrease related to a reduction in total KWHs generated as a result of milder weather in the third quarter 2012, a $16 million decrease in the cost of fuel, a $12 million decrease in the average cost of purchased power, and a $4 million decrease in KWHs purchased.

For year-to-date 2012, total fuel and purchased power expenses were $1.33 billion compared to $1.55 billion for the corresponding period in 2011. The decrease was primarily due to a $176 million decrease related to a reduction in total KWHs generated as a result of milder weather for year-to-date 2012, a $69 million decrease in the average cost of purchased power, and a $36 million decrease in the cost of fuel, partially offset by a $59 million increase in KWHs purchased.

Fuel and purchased power energy transactions do not have a significant impact on earnings since energy expenses are generally offset by energy revenues through Alabama Power's Energy Cost Recovery Rate mechanism. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Retail Fuel Cost Recovery" herein for additional information.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Fuel

In the third quarter 2012, fuel expense was $469 million compared to $512 million for the corresponding period in 2011. The $43 million decrease was due to a 21.7% decrease in the average cost of KWHs generated by natural gas, which excludes fuel associated with tolling agreements, and a 6.2% decrease in KWHs generated by coal, slightly offset by a 1.5% increase in KWHs generated by natural gas.

For year-to-date 2012, fuel expense was $1.12 billion compared to $1.34 billion for the corresponding period in 2011. The $217 million decrease was due to a 27.9% decrease in the average cost of KWHs generated by natural gas, which excludes fuel associated with tolling agreements, and a 20.8% decrease in KWHs generated by coal, slightly offset by a 6.0% increase in KWHs generated by natural gas.

Purchased Power – Non-Affiliates

In the third quarter 2012, purchased power expense from non-affiliates was $31 million compared to $34 million for the corresponding period in 2011. The decrease was related to a 34.8% decrease in the average cost per KWH, partially offset by a 25.2% increase in the amount of energy purchased.

For year-to-date 2012, purchased power expense from non-affiliates was $63 million compared to $62 million for the corresponding period in 2011. The increase was related to a 129.6% increase in the amount of energy purchased, partially offset by a 58.8% decrease in the average cost per KWH.

Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation.

Purchased Power – Affiliates

In the third quarter 2012, purchased power expense from affiliates was $41 million compared to $49 million for the corresponding period in 2011. The decrease was related to a 13.9% decrease in the amount of energy purchased and a 2.6% decrease in the average cost per KWH.

For year-to-date 2012, purchased power expense from affiliates was $147 million compared to $152 million for the corresponding period in 2011. The decrease was related to a 13.5% decrease in the average cost per KWH, partially offset by an 11.4% increase in the amount of energy purchased.

Energy purchases from affiliates will vary depending on demand for energy and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other contractual agreements, as approved by the FERC.

The decrease for year-to-date 2012 was primarily due to lower pre-tax earnings as a result of lower revenues due to milder weather and an increase in operations and maintenance expense.

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Alabama Power's future earnings potential. The level of Alabama Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Alabama Power's primary business of selling electricity. These factors include Alabama Power's ability to maintain a constructive regulatory environment that continues to allow for the timely recovery of prudently incurred costs during a time of increasing costs. Future earnings in the near term will depend, in part, upon maintaining energy sales which are subject to a number of factors. These factors include weather, competition, new energy contracts with neighboring utilities, energy conservation practiced by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or decline in Alabama Power's service territory. Changes in economic conditions impact sales for Alabama Power and the pace of the economic recovery remains uncertain. The timing and extent of the economic recovery will impact growth and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Alabama Power in Item 7 of the Form 10-K.

Environmental Matters

Compliance costs related to federal and state environmental statutes and regulations could affect earnings if such costs cannot continue to be fully recovered in rates on a timely basis. Environmental compliance spending over the next several years may differ materially from the amounts estimated. The timing, specific requirements, and estimated costs could change as environmental statutes and regulations are adopted or modified. Further, higher costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could negatively affect results of operations, cash flows, and financial condition. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" of Alabama Power in Item 7 and Note 3 to the financial statements of Alabama Power under "Environmental Matters" in Item 8 of the Form 10-K for additional information.

ALABAMA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Alabama Power is continuing to develop its compliance strategy and to assess the potential costs of complying with the MATS rule and the EPA's proposed water and coal combustion byproducts rules. As part of the development of its compliance strategy for the MATS rule, Alabama Power has entered into agreements for the construction of baghouses on generating units with an aggregate capacity of 1,901 MWs and plans to utilize additional compliance strategies at other units with an aggregate capacity of 4,678 MWs including utilizing existing or additional natural gas capability and/or using additives or other injection technologies. Certain transmission system upgrades may also be required. While the final MATS compliance plan is still being developed and the ultimate costs remain uncertain, the compliance decisions made in 2012 have allowed Alabama Power to further develop its cost estimates for compliance with the MATS rule. As a result, estimated compliance costs for the MATS rule in the 2012 through 2014 period have been revised from up to $1.2 billion to approximately $585 million as follows:

	2012		2013		2014
	(in millions)
MATS rule	$	55	$	180	$	350

In addition, Alabama Power has further developed its estimated capital expenditures and associated timing of these expenditures to comply with the proposed water and coal combustion byproducts rules, resulting in a reduction, due primarily to timing, in estimated compliance costs for 2012 through 2014. Potential incremental environmental compliance investments to comply with the proposed water and coal combustion byproducts rules have been revised from up to $630 million to approximately $175 million over the 2012 through 2014 period, based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule. These potential incremental environmental compliance investments are estimated as follows:

	2012		2013		2014
	(in millions)
Proposed water and coal combustion byproducts rules	$	5	$	10	$	160

While Alabama Power's ultimate costs of compliance with the MATS rule and the proposed water and coal combustion byproducts rules remain uncertain, Alabama Power estimates that compliance costs through 2021 (assuming that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) will be at the low end of the $5 billion to $7 billion range provided in the Form 10-K.

Alabama Power's ultimate compliance strategy and actual future environmental capital expenditures are dependent on development of the final MATS compliance plan and will be affected by the final requirements of new or revised environmental regulations that are promulgated; the outcome of any legal challenges to the environmental rules; the cost, availability, and existing inventory of emissions allowances; and Alabama Power's fuel mix. Compliance costs may arise from retirement and replacement of existing units, installation of additional environmental controls, upgrades to the transmission system, and changing fuel sources for certain existing units. The ultimate outcome of these matters cannot be determined at this time.

As part of SEGCO's environmental compliance strategy, the Board of Directors of SEGCO approved adding natural gas as the primary fuel source in 2015 for its 1,000 MWs of generating capacity and the construction of the necessary natural gas pipeline. SEGCO is jointly owned by Alabama Power and Georgia Power. The capacity of SEGCO's units is sold to Alabama Power and Georgia Power through a PPA. See Note 4 to the financial statements of Alabama Power in Item 8 of the Form 10-K for additional information. The impact of SEGCO's ultimate compliance strategy on the PPA costs cannot be determined at this time; however, if such costs cannot continue to be recovered through retail rates, they could have a material impact on Alabama Power's financial statements.

Air Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality" of Alabama Power in Item 7 of the Form 10-K for additional information on the eight-hour ozone and fine particulate matter air quality standards, the MATS rule, the Cross-State Air Pollution Rule (CSAPR), and the Clean Air Visibility Rule (CAVR).

On May 21, 2012, the EPA published its final determination of nonattainment areas based on the 2008 eight-hour ozone air quality standards. None of the areas within Alabama Power's service territory were designated as nonattainment areas.

On June 14, 2012, the EPA proposed a rule that would increase the stringency of the fine particulate matter national ambient air quality standards. If adopted, the proposed standards could result in the designation of new nonattainment areas within Alabama Power's service territory. As part of a related settlement, the EPA has agreed to finalize the proposed rule by December 14, 2012. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Numerous petitions for administrative reconsideration of the MATS rule, including a petition by Southern Company and its subsidiaries, including Alabama Power, have been filed with the EPA. Challenges to the final rule have also been filed in the U.S. District Court for the District of Columbia by numerous states, environmental organizations, industry groups, and others. The impact of the MATS rule will depend on the outcome of these and any other legal challenges and, therefore, cannot be determined at this time.

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR in its entirety and directed the EPA to continue to administer the Clean Air Interstate Rule pending the EPA's development of a valid replacement. The vacatur of CSAPR creates additional uncertainty with respect to whether additional controls may be required for CAVR and best available retrofit technology compliance. On October 5, 2012, the EPA filed for review of the decision by the U.S. Court of Appeals for the District of Columbia Circuit. The ultimate outcome of this matter depends on the outcome of any legal challenges and further action by the EPA and cannot be determined at this time.

On August 29, 2012, the EPA published proposed revisions to the New Source Performance Standard (NSPS) for Stationary Combustion Turbines (CTs). If finalized, the revisions would apply the NSPS to all new, reconstructed, and modified CTs, including CTs at combined cycle units, during all periods of operation, including startup and shutdown, and alter the criteria for determining when an existing CT has been reconstructed. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Water Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Water Quality" of Alabama Power in Item 7 of the Form 10-K for additional information on the proposed rules regarding certain cooling water intake structures. The EPA has entered into an amended settlement agreement to extend the deadline for issuing a final rule until June 27, 2013.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Coal Combustion Byproducts" of Alabama Power in Item 7 of the Form 10-K for additional information. Environmental groups and other parties have filed lawsuits in the U.S. District Court for the District of Columbia seeking to require the EPA to complete its rulemaking process and issue final regulations pertaining to the regulation of coal combustion byproducts. The ultimate outcome of these matters cannot be determined at this time.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Alabama Power in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

At September 30, 2012, the NDR had an accumulated balance of $102 million, which is included in Alabama Power's Condensed Balance Sheet herein under other regulatory liabilities, deferred. The accruals are reflected as operations and maintenance expenses in Alabama Power's Condensed Statement of Income herein.

Compliance and Pension Cost Accounting Order

On November 6, 2012, the Alabama PSC approved an accounting order for certain compliance-related operations and maintenance expenditures for the years 2013 through 2017, as well as the incremental increase in operations expense related to pension cost for 2013. Under the accounting order, expenses from January 2013 through December 2017 related to compliance with standards addressing Critical Infrastructure Protection issued by the North American Electric Reliability Corporation and cyber security requirements issued by the NRC will be deferred to a regulatory asset account and amortized over a three-year period beginning in January 2015. Expenses from January 2013 through December 2017 related to compliance with NRC guidance addressing the readiness at nuclear facilities within the U.S., as prompted by the earthquake and tsunami that struck Japan in 2011, also will be deferred as a regulatory asset and recovered over the same amortization period. The compliance-related expenses to be afforded regulatory asset treatment over the five-year period are currently estimated to be approximately $43 million. See "Other Matters" herein for information regarding the NRC's guidance issued as a result of the earthquake and tsunami that struck Japan in 2011. In addition, the accounting order authorizes Alabama Power to defer an incremental increase in its pension cost for 2013. The increased pension cost is estimated to be approximately $17 million. During 2013, the actual incremental increase will be deferred to a regulatory asset account and will be amortized over a three-year period beginning in January 2015. Pursuant to the accounting order, Alabama Power has the ability to accelerate the amortization of the regulatory assets.

Alabama Power expects that the accounting order and other cost containment measures will preclude a need for a rate adjustment under Rate RSE.

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013), which will have a positive impact on the future cash flows of Alabama Power through 2013. Consequently, Alabama Power's positive cash flow benefit is estimated to be between $105 million and $120 million in 2012.

Other Matters

Alabama Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Alabama Power is subject to certain claims and legal actions arising in the ordinary course of business. Alabama Power's business activities are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Alabama Power cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Alabama Power in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Alabama Power's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Other Matters" of Alabama Power in Item 7 of the Form 10-K for additional information regarding the earthquake and tsunami that struck Japan in March 2011. On March 12, 2012, the NRC issued three orders and a request for information based on the NRC task force report recommendations that included, among other items, additional mitigation strategies for beyond-design-basis events, enhanced spent fuel pool instrumentation capabilities, hardened vents for certain classes of containment structures, site specific evaluations for seismic and flooding hazards, and various plant evaluations to ensure adequate coping capabilities during station blackout and other conditions. On August 29, 2012, the NRC staff issued the final interim staff guidance document, which offers acceptable approaches to meeting the requirements of the NRC's orders before the December 31, 2016 compliance deadline. The interim staff guidance is not mandatory, but licensees would be required to obtain NRC approval for taking an approach other than as outlined in the interim staff guidance. The final form and the resulting impact of any changes to safety requirements for nuclear reactors will be dependent on further review and action by the NRC and cannot be determined at this time. See RISK FACTORS of Alabama Power in Item 1A of the Form 10-K for a discussion of certain risks associated with the operation of nuclear generating units, including potential impacts that could result from a major incident at a nuclear facility anywhere in the world. The ultimate outcome of these events cannot be determined at this time.

See "PSC Matters – Compliance and Pension Cost Accounting Order" herein for additional information on Alabama Power's PSC approved accounting order, which allows the deferral of certain compliance-related operations and maintenance expenditures related to compliance with the NRC guidance.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Alabama Power prepares its financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Alabama Power in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Alabama Power's results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Alabama Power in Item 7 of the Form 10-K for a complete discussion of Alabama Power's critical accounting policies and estimates related to Electric Utility Regulation, Contingent Obligations, and Pension and Other Postretirement Benefits.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" of Alabama Power in Item 7 of the Form 10-K for additional information. Alabama Power's financial condition remained stable at September 30, 2012. Alabama Power intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities," and "Capital Requirements and Contractual Obligations" herein for additional information.

Net cash provided from operating activities totaled $1.1 billion for the first nine months of 2012, a decrease of $473 million as compared to the first nine months of 2011. The decrease in cash provided from operating activities was primarily due to an increase in fossil fuel stock, a decrease in deferred income taxes, and the timing of income tax payments and refunds associated with bonus depreciation. Net cash used for investing activities totaled $646 million for the first nine months of 2012 primarily due to gross property additions related to nuclear fuel and transmission, distribution, and steam generating equipment. Net cash used for financing activities totaled $417 million for the first nine months of 2012. This was primarily due to the payment of common stock dividends.

Fluctuations in cash flow from financing activities vary year to year based on capital needs and the maturity or redemption of securities.

Significant balance sheet changes for the first nine months of 2012 include increases of $200 million of securities due within one year, $187 million in retained earnings, $134 million in property, plant, and equipment associated with routine property additions, $114 million in customer accounts receivable due to seasonal variations in customer usage, $109 million in accumulated deferred income taxes related to bonus depreciation, and $93 million in fossil fuel stock, at average cost, and decreases of $202 million in long-term debt and $144 million in other accounts payable associated with the timing of property tax payments.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Alabama Power in Item 7 of the Form 10-K for a description of Alabama Power's capital requirements for its construction program, including estimated capital expenditures to comply with existing environmental regulations, scheduled maturities of long-term debt, as well as the related interest, derivative obligations, preferred and preference stock dividends, leases, purchase commitments, trust funding requirements, and unrecognized tax benefits. Approximately $700 million will be required through September 30, 2013 to fund maturities and announced redemptions of long-term debt.

ALABAMA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Alabama Power's updated construction program for 2013 and 2014 includes anticipated costs for MATS compliance but does not include the potential incremental compliance cost estimates for the proposed water and coal combustion byproducts rules. Alabama Power's updated base level construction program and the potential incremental environmental compliance estimates for the proposed water and coal combustion byproducts rules (based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) for 2013 and 2014 are as follows:

	2013		2014
Construction program:	(in millions)
Base capital	$	954	$	1,117
Existing environmental statutes and regulations, including MATS	195		424
Total construction program base level capital investment	$	1,149	$	1,541
Potential incremental environmental compliance investment:
Proposed water and coal combustion byproducts rules	$	10	$	160

See FUTURE EARNINGS POTENTIAL – "Environmental Statutes and Regulations – General" herein for additional information on Alabama Power's estimated capital expenditures to comply with the MATS rule and proposed water and coal combustion byproducts rules.

The construction program is subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; changes in environmental statutes and regulations; the outcome of any legal challenges to the environmental rules; changes in generating plants, including unit retirements and replacements and adding or changing fuel sources at existing units, to meet new regulatory requirements; changes in the expected environmental compliance program; changes in FERC rules and regulations; Alabama PSC approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; storm impacts; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.

Sources of Capital

Alabama Power plans to obtain the funds required for construction and other purposes from sources similar to those utilized in the past. Alabama Power has primarily utilized funds from operating cash flows, short-term debt, security issuances, and equity contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend upon regulatory approval, prevailing market conditions, and other factors. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Alabama Power in Item 7 of the Form 10-K for additional information.

Alabama Power's current liabilities sometimes exceed current assets because of Alabama Power's debt due within one year and the periodic use of short-term debt as a funding source primarily to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate significantly due to the seasonality of the business.

At September 30, 2012, Alabama Power had approximately $366 million of cash and cash equivalents. Committed credit arrangements with banks at September 30, 2012, including expiration dates, were as follows:

Expires										Executable Term Loans				Due Within One Year(a)
2012		2013		2014 and Beyond		Total		Unused		One Year		Two Years		Term Out		No Term Out

ALABAMA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

See Note 6 to the financial statements of Alabama Power under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Most of these arrangements contain covenants that limit debt levels and typically contain cross default provisions that are restricted only to the indebtedness of Alabama Power. Alabama Power is currently in compliance with all such covenants. Alabama Power expects to renew its credit arrangements, as needed, prior to expiration. These credit arrangements provide liquidity support to Alabama Power's commercial paper borrowings and variable rate pollution control revenue bonds. The amount of variable rate pollution control revenue bonds outstanding requiring liquidity support as of September 30, 2012 was approximately $793 million.

Alabama Power may meet short-term cash needs through its commercial paper program. Alabama Power may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell commercial paper at the request and for the benefit of Alabama Power and the other traditional operating companies. Proceeds from such issuances for the benefit of Alabama Power are loaned directly to Alabama Power. The obligations of each traditional operating company under these arrangements are several and there is no cross affiliate credit support.

During the three months ended September 30, 2012, Alabama Power had no commercial paper or other short-term debt outstanding.

Management believes that the need for working capital can be adequately met by utilizing commercial paper programs, lines of credit, and cash.

Credit Rating Risk

Alabama Power does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to below BBB- and/or Baa3. These contracts are primarily for physical electricity purchases, fuel purchases, fuel transportation and storage, and energy price risk management. At September 30, 2012, the maximum potential collateral requirements under these contracts at a rating below BBB- and/or Baa3 were approximately $291 million. Included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, any credit rating downgrade could impact Alabama Power's ability to access capital markets, particularly the short-term debt market.

Market Price Risk

Alabama Power's market risk exposure relative to interest rate changes for the third quarter 2012 has not changed materially compared to the December 31, 2011 reporting period. Since a significant portion of outstanding indebtedness is at fixed rates, Alabama Power is not aware of any facts or circumstances that would significantly affect exposures on existing indebtedness in the near term. However, the impact on future financing costs cannot now be determined.

Due to cost-based rate regulation and other various cost recovery mechanisms, Alabama Power continues to have limited exposure to market volatility in interest rates, commodity fuel prices, and prices of electricity. To mitigate residual risks relative to movements in electricity prices, Alabama Power enters into physical fixed-price contracts for the purchase and sale of electricity through the wholesale electricity market and, to a lesser extent, financial hedge contracts for natural gas purchases. Alabama Power continues to manage a retail fuel-hedging program implemented per the guidelines of the Alabama PSC. As such, Alabama Power had no material change in market risk exposure for the third quarter 2012 when compared with the December 31, 2011 reporting period.

ALABAMA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The changes in fair value of energy-related derivative contracts, substantially all of which are composed of regulatory hedges, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(32	)	$	(48	)
Contracts realized or settled	12			41
Current period changes(a)	12			(1		)
Contracts outstanding at the end of the period, assets (liabilities), net	$	(8	)	$	(8	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

The changes in the fair value positions of the energy-related derivative contracts, which are substantially all attributable to both the volume and the price of natural gas, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes		Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Natural gas swaps	$	19	$	33
Natural gas options	5		7
Total changes	$	24	$	40

The net hedge volumes of energy-related derivative contracts were as follows:

	September 30, 2012	June 30, 2012	December 31, 2011
	mmBtu Volume
	(in millions)
Commodity – Natural gas swaps	41	32	30
Commodity – Natural gas options	14	11	9
Total hedge volume	55	43	39

The weighted average swap contract cost above market prices was approximately $0.25 per mmBtu as of September 30, 2012, $0.93 per mmBtu as of June 30, 2012, and $1.45 per mmBtu as of December 31, 2011. The change in option premiums is primarily attributable to the volatility of the market and the underlying change in the natural gas price. A majority of the natural gas hedge gains and losses is recovered through Alabama Power's retail fuel cost recovery clause.

Regulatory hedges relate to Alabama Power's fuel-hedging program where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through Alabama Power's fuel cost recovery clause.

Unrealized pre-tax gains and losses recognized in income for the three and nine months ended September 30, 2012 and 2011 for energy-related derivative contracts that are not hedges were not material.

ALABAMA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Alabama Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows:

	September 30, 2012 Fair Value Measurements
	Total Fair Value			Maturity
				Year 1			Years 2&3		Years 4&5
	(in millions)
Level 1	$	—		$	—		$	—	$	—
Level 2	(8		)	(11		)	3		—
Level 3	—			—			—		—
Fair value of contracts outstanding at end of period	$	(8	)	$	(11	)	$	3	$	—

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Alabama Power. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Alabama Power and its derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Alabama Power does not expect the impact of these rules to be material.

For additional information, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" of Alabama Power in Item 7 and Note 1 under "Financial Instruments" and Note 11 to the financial statements of Alabama Power in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein.

Financing Activities

In January 2012, Alabama Power issued $250 million aggregate principal amount of Series 2012A 4.10% Senior Notes due January 15, 2042. The proceeds were used for general corporate purposes, including Alabama Power's continuous construction program. Alabama Power settled $100 million of interest rate swaps related to this issuance at a loss of $1 million. The loss is being amortized to interest expense, in earnings, over 10 years.

In March 2012, Alabama Power redeemed approximately $1 million aggregate principal amount of The Industrial Development Board of the Town of West Jefferson Solid Waste Disposal Revenue Bonds (Alabama Power Company Miller Plant Project), Series 2008.

In April 2012, Alabama Power redeemed $250 million aggregate principal amount of its Series 2007B 5.875% Senior Notes due April 1, 2047.

Subsequent to September 30, 2012, Alabama Power issued $400 million aggregate principal amount of Series 2012B 0.550% Senior Notes due October 15, 2015. The proceeds were used to redeem, on October 15, 2012, $200 million aggregate principal amount of Series 2007C 6.00% Senior Insured Monthly Notes due October 15, 2037 and for general corporate purposes, including Alabama Power's continuous construction program.

In addition to any financings that may be necessary to meet capital requirements and contractual obligations, Alabama Power plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-cost capital if market conditions permit.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Georgia Power operates as a vertically integrated utility providing electricity to retail customers within its traditional service territory located within the State of Georgia and to wholesale customers in the Southeast. Many factors affect the opportunities, challenges, and risks of Georgia Power's business of selling electricity. These factors include the ability to maintain a constructive regulatory environment, to maintain and grow energy sales given economic conditions, and to effectively manage and secure timely recovery of costs. These costs include those related to projected long-term demand growth, increasingly stringent environmental standards, reliability, and fuel. In addition, Georgia Power is currently constructing two new nuclear units. Appropriately balancing required costs and capital expenditures with customer prices will continue to challenge Georgia Power for the foreseeable future.

Georgia Power continues to focus on several key performance indicators. These indicators include customer satisfaction, plant availability, system reliability, and net income after dividends on preferred and preference stock. For additional information on these indicators, see MANAGEMENT'S DISCUSSION AND ANALYSIS – OVERVIEW – "Key Performance Indicators" of Georgia Power in Item 7 of the Form 10-K.

RESULTS OF OPERATIONS

Net Income

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$5	1.0	$(48)	(4.6)

Georgia Power's net income after dividends on preferred and preference stock for the third quarter 2012 was $525 million compared to $520 million for the corresponding period in 2011. The increase was primarily due to lower non-fuel operating expenses largely offset by lower retail revenues, as well as lower AFUDC and higher income taxes. Retail revenues in the third quarter 2012 decreased primarily due to milder weather and a decrease in customer usage, partially offset by an increase related to retail revenue rate effects.

Georgia Power's net income after dividends on preferred and preference stock for year-to-date 2012 was $987 million compared to $1.04 billion for the corresponding period in 2011. The decrease was primarily due to lower operating revenues primarily as a result of milder weather and a decrease in customer usage, as well as lower AFUDC, higher interest expense reflecting a 2011 litigation settlement, and higher depreciation and amortization. These income reductions were partially offset by retail revenue rate effects, lower operations and maintenance expenses, and lower income taxes.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Details of the change to retail revenues were as follows:

	Third Quarter 2012					Year-to-Date 2012
	(in millions)			(% change)		(in millions)			(% change)
Retail – prior year	$	2,609				$	6,494
Estimated change in –
Rates and pricing	60			2.3		108			1.7
Sales growth (decline)	(39		)	(1.5	)	(44		)	(0.7	)
Weather	(64		)	(2.4	)	(157		)	(2.4	)
Fuel cost recovery	(231		)	(8.9	)	(615		)	(9.5	)
Retail – current year	$	2,335		(10.5	)%	$	5,786		(10.9	)%

Revenues associated with changes in rates and pricing increased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 due to base tariff increases effective April 1, 2012 related to placing Plant McDonough-Atkinson Units 4 and 5 in service, the NCCR and demand-side management tariff increases effective January 1, 2012, as approved by the Georgia PSC, and, for year-to-date 2012, the rate pricing effect of decreased customer usage. These increases were partially offset by lower contributions from market-driven rates from commercial and industrial customers.

Revenues attributable to changes in sales decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011. Weather-adjusted residential KWH sales decreased 4.0%, weather-adjusted commercial KWH sales decreased 0.2%, and weather-adjusted industrial KWH sales decreased 1.7% in the third quarter 2012 when compared to the corresponding period in 2011. Weather-adjusted residential KWH sales decreased 1.3%, weather-adjusted commercial KWH sales decreased 0.5%, and weather-adjusted industrial KWH sales decreased 1.0% for year-to-date 2012 when compared to the corresponding period in 2011. Georgia Power had an increase of over 12,000 new residential customers in 2012. However, weather-adjusted usage per residential customer decreased 4.5% and 1.9% in the third quarter and year-to-date 2012, respectively. In addition to the continued impact of the sluggish economy, Georgia Power implemented five residential and two commercial energy efficiency programs in 2011. Participation in these programs has continued to increase and has reduced residential and commercial KWH energy sales by approximately 0.2% and 0.3%, respectively, for year-to-date 2012 when compared to the corresponding period in 2011.

Revenues resulting from changes in weather decreased in the third quarter 2012 when compared to the corresponding period in 2011 due to milder weather in 2012. Revenues resulting from changes in weather decreased year-to-date 2012 when compared to the corresponding period in 2011 as a result of milder weather in 2012 and cold weather in January 2011.

Fuel revenues and costs are allocated between retail and wholesale jurisdictions. Retail fuel cost recovery revenues decreased $231 million and $615 million in the third quarter and year-to-date 2012, respectively, when compared to the corresponding periods in 2011 due to both lower demand, as discussed above, and lower costs primarily due to lower natural gas prices.

Electric rates include provisions to adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these fuel cost recovery provisions, fuel revenues generally equal fuel expenses, including the energy component of purchased power costs, and do not affect net income. Georgia Power lowered fuel rates effective June 1, 2012 and has filed a request with the Georgia PSC to further lower fuel rates effective January 1, 2013. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Fuel Cost Recovery" herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Wholesale Revenues – Non-Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(17)	(18.9)	$(56)	(20.7)

Wholesale revenues from sales to non-affiliates consist of PPAs and short-term opportunity sales. Wholesale revenues from PPAs have both capacity and energy components. Capacity revenues reflect the recovery of fixed costs and a return on investment. Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy compared to the cost of Georgia Power's and the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. Short-term opportunity sales are made at market-based rates that generally provide a margin above Georgia Power's variable cost of energy.

In the third quarter 2012, wholesale revenues from non-affiliates were $73 million compared to $90 million in the corresponding period in 2011. For year-to-date 2012, wholesale revenues from non-affiliates were $214 million compared to $270 million in the corresponding period in 2011. The decreases were primarily due to 24.2% and 32.7% decreases in KWH sales in the third quarter and year-to-date 2012, respectively, due to lower demand resulting from milder weather and the availability of market energy at a lower cost than Georgia Power-owned generation.

Wholesale Revenues – Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$1	25.0	$(17)	(54.8)

Wholesale revenues from sales to affiliated companies within the Southern Company system will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since the energy is generally sold at marginal cost.

In the third quarter 2012 and 2011, wholesale revenues from affiliates were immaterial. For year-to-date 2012, wholesale revenues from affiliates were $14 million compared to $31 million in the corresponding period in 2011. The decrease was primarily due to a 31.3% decrease in KWH sales due to lower demand resulting from milder weather in 2012 and the availability of market energy at a lower cost than Georgia Power-owned generation.

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In the third quarter 2012, total fuel and purchased power expenses were $890 million compared to $1.16 billion in the corresponding period in 2011. For year-to-date 2012, total fuel and purchased power expenses were $2.38 billion compared to $3.11 billion for the corresponding period in 2011. The decreases were primarily due to the lower cost of natural gas used for generation and lower demand related to milder weather in 2012.

Fuel and purchased power energy transactions do not have a significant impact on earnings since energy expenses are generally offset by energy revenues through Georgia Power's fuel cost recovery mechanism. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Fuel Cost Recovery" herein for additional information.

Details of Georgia Power's generation and purchased power were as follows:

	Third Quarter 2012	Third Quarter 2011	Year-to-Date 2012	Year-to-Date 2011
Total generation (billions of KWHs)	17	19	46	53

Average cost of purchased power (cents per net KWH)(a)	4.45	5.51	4.18	5.61

(a) Average cost of purchased power includes fuel purchased by Georgia Power for tolling agreements where power is generated by the provider.

Fuel

In the third quarter 2012, fuel expense was $630 million compared to $838 million in the corresponding period in 2011. The decrease was primarily due to a 6.3% decrease in KWHs generated as a result of lower KWH demand and a 19.6% decrease in the average cost of fuel per KWH generated primarily due to lower natural gas prices.

For year-to-date 2012, fuel expense was $1.64 billion compared to $2.30 billion in the corresponding period in 2011. The decrease was primarily due to a 12.3% decrease in KWHs generated as a result of lower KWH demand and an 18.2% decrease in the average cost of fuel per KWH generated primarily due to lower natural gas prices.

Purchased Power – Non-Affiliates

In the third quarter 2012, purchased power expense from non-affiliates was $79 million compared to $127 million in the corresponding period in 2011. The decrease was due to a 21.8% decrease in the volume of KWHs purchased and a decrease of 14.0% in the average cost per KWH purchased primarily due to lower natural gas prices.

For year-to-date 2012, purchased power expense from non-affiliates was $266 million compared to $297 million in the corresponding period in 2011. The decrease was due to a decrease of 30.4% in the average cost per KWH purchased primarily due to lower natural gas prices, partially offset by a 30.3% increase in the volume of KWHs purchased as the market cost of available energy was lower than the additional Georgia Power-owned generation available.

70

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation.

Purchased Power – Affiliates

In the third quarter 2012, purchased power expense from affiliates was $181 million compared to $193 million in the corresponding period in 2011. The decrease was due to an 18.8% decrease in the average cost per KWH purchased, reflecting lower natural gas prices, partially offset by a 6.4% increase in the volume of KWHs purchased as the cost of available energy was lower than the Georgia Power-owned generation available.

For year-to-date 2012, purchased power expense from affiliates was $469 million compared to $513 million in the corresponding period in 2011. The decrease was due to a 24.9% decrease in the average cost per KWH purchased, reflecting lower natural gas prices, partially offset by a 10.4% increase in the volume of KWHs purchased as the cost of the available energy was lower than the Georgia Power-owned generation available.

Energy purchases from affiliates will vary depending on the demand and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other contractual agreements, all as approved by the FERC.

Other Operations and Maintenance Expenses

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(55)	(12.1)	$(51)	(3.9)

In the third quarter 2012, other operations and maintenance expenses were $398 million compared to $453 million in the corresponding period in 2011. For year-to-date 2012, other operations and maintenance expenses were $1.24 billion compared to $1.29 billion in the corresponding period in 2011. The decreases in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 were primarily due to decreases in transmission and distribution maintenance and the timing of outages as the result of cost containment efforts to offset the effect of milder weather in 2012, and decreases in uncollectible account expense of $6 million and $15 million, respectively, partially offset by increases in employee benefits expense of $10 million and $30 million, respectively.

Depreciation and Amortization

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$6	3.3	$28	5.3

In the third quarter 2012, depreciation and amortization was $186 million compared to $180 million in the corresponding period in 2011. For year-to-date 2012, depreciation and amortization was $559 million compared to $531 million in the corresponding period in 2011. The increases were primarily due to increases of $15 million and $42 million, respectively, in depreciation on additional plant in service primarily related to new generation at Plant McDonough-Atkinson Units 4 and 5, partially offset by $9 million and $18 million, respectively, in amortization of the regulatory liability for state income tax credits as authorized by the Georgia PSC. See Note 3 to the financial statements of Georgia Power under "Income Tax Matters – Georgia State Income Tax Credits" in Item 8 of the Form 10-K.

In the third quarter 2012, AFUDC equity was $15 million compared to $26 million in the corresponding period in 2011. For year-to-date 2012, AFUDC equity was $41 million compared to $73 million in the corresponding period in 2011. The decreases were primarily due to the completion of Plant McDonough-Atkinson Units 4 and 5 in December 2011 and April 2012, respectively.

Interest Expense, Net of Amounts Capitalized

$5	5.6	$19	7.4

In the third quarter 2012, interest expense, net of amounts capitalized was $95 million compared to $90 million in the corresponding period in 2011. The increase was immaterial. For year-to-date 2012, interest expense, net of amounts capitalized was $276 million compared to $257 million in the corresponding period in 2011. The increase was primarily due to a $23 million reduction in interest expense in 2011 resulting from the settlement of litigation with the Georgia Department of Revenue, as well as a $10 million decrease in allowance for debt funds used during construction due to the completion of Plant McDonough-Atkinson Units 4 and 5 discussed above. See Note 3 to the financial statements of Georgia Power under "Income Tax Matters – Georgia State Income Tax Credits" in Item 8 of the Form 10-K for additional information on the litigation settlement.

(change in millions)	(% change)	(change in millions)	(% change)
$11	3.6	$(25)	(4.3)

In the third quarter 2012, income taxes were $314 million compared to $303 million in the corresponding period in 2011. The increase was primarily due to higher pre-tax earnings and a decrease in non-taxable AFUDC equity.

For year-to-date 2012, income taxes were $558 million compared to $583 million in the corresponding period in 2011. The decrease was primarily due to lower pre-tax earnings and state income tax credits, partially offset by a decrease in non-taxable AFUDC equity.

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Georgia Power's future earnings potential. The level of Georgia Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Georgia Power's business of selling electricity. These factors include Georgia Power's ability to maintain a constructive regulatory environment that continues to allow for the timely recovery of prudently incurred costs during a time of increasing costs. Future earnings in the near term will depend, in part, upon maintaining energy sales which is subject to a number of factors. These factors include weather, competition, new energy contracts with neighboring utilities, energy conservation practiced by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or decline in Georgia Power's service territory. Changes in economic conditions impact sales for Georgia Power and the pace of the economic recovery remains uncertain. The timing and extent of the economic recovery will impact growth and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Georgia Power in Item 7 of the Form 10-K.

Environmental Matters

Compliance costs related to federal and state environmental statutes and regulations could affect earnings if such costs cannot continue to be fully recovered in rates on a timely basis. Environmental compliance spending over the next several years may differ materially from the amounts estimated. The timing, specific requirements, and estimated costs could change as environmental statutes and regulations are adopted or modified. Further, higher costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could negatively affect results of operations, cash flows, and financial condition. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" of Georgia Power in Item 7 and Note 3 to the financial statements of Georgia Power under "Environmental Matters" in Item 8 of the Form 10-K for additional information.

Environmental Statutes and Regulations

General

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – General" of Georgia Power in Item 7 of the Form 10-K for information regarding Georgia Power's estimated base level capital expenditures to comply with existing statutes and regulations for 2012 through 2014, as well as Georgia Power's preliminary estimates for potential incremental environmental compliance investments associated with complying with the EPA's final Mercury and Air Toxics Standards (MATS) rule (formerly referred to as the Utility Maximum Achievable Control Technology rule) and the EPA's proposed water and coal combustion byproducts rules.

73

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Georgia Power is continuing to develop its compliance strategy and to assess the potential costs of complying with the MATS rule and the EPA's proposed water and coal combustion byproducts rules. As part of the development of its compliance strategy for the MATS rule, Georgia Power has entered into agreements for the construction of baghouses to control the emissions of mercury and particulates from certain generating units. While the final MATS compliance plan is still being developed and the ultimate costs remain uncertain, compliance decisions made in 2012 have allowed Georgia Power to further develop its cost estimates for compliance with the MATS rule. As a result, estimated compliance costs for the MATS rule in the 2012 through 2014 period (in addition to $237 million included in base environmental capital disclosed in the Form 10-K) have been revised from up to $320 million to approximately $440 million as follows:

	2012		2013		2014
			(in millions)
MATS rule	$	—	$	—	$	440

In addition, Georgia Power has further developed its estimated capital expenditures and associated timing of these expenditures to comply with the proposed water and coal combustion byproducts rules, resulting in a reduction, due primarily to timing, in estimated compliance costs for 2012 through 2014. Potential incremental environmental compliance investments to comply with the proposed water and coal combustion byproducts rules have been revised from up to $640 million to approximately $250 million over the 2012 through 2014 period, based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule. These potential incremental environmental compliance investments are estimated as follows:

	2012		2013		2014
			(in millions)
Proposed water and coal combustion byproducts rules	$	5	$	55	$	190

While Georgia Power's ultimate costs of compliance with the MATS rule and the proposed water and coal combustion byproducts rules remain uncertain, Georgia Power estimates that compliance costs through 2021 (assuming that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) will be at the low end of the $5 billion to $7 billion range provided in the Form 10-K.

Georgia Power's ultimate compliance strategy and actual future environmental capital expenditures are dependent on development of the final MATS compliance plan and will be affected by the final requirements of new or revised environmental regulations that are promulgated; the outcome of any legal challenges to the environmental rules; the cost, availability, and existing inventory of emissions allowances; and Georgia Power's fuel mix. Compliance costs may arise from retirement and replacement of existing units, installation of additional environmental controls, upgrades to the transmission system, and changing fuel sources for certain existing units. The ultimate outcome of these matters cannot be determined at this time.

As part of SEGCO's environmental compliance strategy, the Board of Directors of SEGCO approved adding natural gas as the primary fuel source in 2015 for its 1,000 MWs of generating capacity and the construction of the necessary natural gas pipeline. SEGCO is jointly owned by Georgia Power and Alabama Power. The capacity of SEGCO's units is sold to Georgia Power and Alabama Power through a PPA. See Note 4 to the financial statements of Georgia Power in Item 8 of the Form 10-K for additional information. The impact of SEGCO's ultimate compliance strategy on the PPA costs cannot be determined at this time; however, if such costs cannot continue to be recovered through retail rates, they could have a material impact on Georgia Power's financial statements.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality" of Georgia Power in Item 7 of the Form 10-K for additional information on the eight-hour ozone and fine particulate matter air quality standards, the MATS rule, the Cross-State Air Pollution Rule (CSAPR), and the Clean Air Visibility Rule (CAVR).

On May 21, 2012, the EPA published its final determination of nonattainment areas based on the 2008 eight-hour ozone air quality standards. The only area within Georgia Power's service territory designated as a nonattainment area was a 15-county area within metropolitan Atlanta. The potential impact of the revised standard and nonattainment designation will depend on further evaluation and implementation by the Georgia Environmental Protection Division and cannot be determined at this time.

On June 14, 2012, the EPA proposed a rule that would increase the stringency of the fine particulate matter national ambient air quality standards. If adopted, the proposed standards could result in the designation of new nonattainment areas within Georgia Power's service territory. As part of a related settlement, the EPA has agreed to finalize the proposed rule by December 14, 2012. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Numerous petitions for administrative reconsideration of the MATS rule, including a petition by Southern Company and its subsidiaries, including Georgia Power, have been filed with the EPA. Challenges to the final rule have also been filed in the U.S. District Court for the District of Columbia by numerous states, environmental organizations, industry groups, and others. The impact of the MATS rule will depend on the outcome of these and any other legal challenges and, therefore, cannot be determined at this time.

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR in its entirety and directed the EPA to continue to administer the Clean Air Interstate Rule pending the EPA's development of a valid replacement. The vacatur of CSAPR creates additional uncertainty with respect to whether additional controls may be required for CAVR and best available retrofit technology compliance. On October 5, 2012, the EPA filed for review of the decision by the U.S. Court of Appeals for the District of Columbia Circuit. The ultimate outcome of this matter depends on the outcome of any legal challenges and further action by the EPA and cannot be determined at this time.

On August 29, 2012, the EPA published proposed revisions to the New Source Performance Standard (NSPS) for Stationary Combustion Turbines (CTs). If finalized, the revisions would apply the NSPS to all new, reconstructed, and modified CTs, including CTs at combined cycle units, during all periods of operation, including startup and shutdown, and alter the criteria for determining when an existing CT has been reconstructed. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Water Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Water Quality" of Georgia Power in Item 7 of the Form 10-K for additional information on the proposed rules regarding certain cooling water intake structures. The EPA has entered into an amended settlement agreement to extend the deadline for issuing a final rule until June 27, 2013. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Coal Combustion Byproducts

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Coal Combustion Byproducts" of Georgia Power in Item 7 of the Form 10-K for additional information. Environmental groups and other parties have filed lawsuits in the U.S. District Court for the District of Columbia seeking to require the EPA to complete its rulemaking process and issue final regulations pertaining to the regulation of coal combustion byproducts. The ultimate outcome of these matters cannot be determined at this time.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Georgia Power in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

PSC Matters

Rate Plans

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Rate Plans" of Georgia Power in Item 7 and Note 3 to the financial statements of Georgia Power under "Retail Regulatory Matters – Rate Plans" in Item 8 of the Form 10-K for additional information on Georgia Power's 2010 ARP.

In accordance with the terms of the 2010 ARP, on November 1, 2012, Georgia Power filed the following tariff adjustments with the Georgia PSC to become effective on January 1, 2013:

• Increase the DSM tariffs by approximately $16 million;

• Increase the traditional base tariffs by approximately $58 million to recover the revenue requirements for Plant McDonough-Atkinson Units 4, 5, and 6 for the period through December 31, 2013, which also reflects a separate settlement agreement associated with the June 30, 2011 quarterly construction monitoring report for Plant McDonough-Atkinson (see Note 3 to the financial statements of Georgia Power under "Construction – Other Construction" in Item 8 of the Form 10-K for additional information); and

• Increase the MFF tariff, consistent with the adjustments above, as well as those related to the IFR and NCCR tariff adjustments described under "Fuel Cost Recovery" and "Construction – Nuclear," respectively, herein.

Fuel Cost Recovery

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Fuel Cost Recovery" of Georgia Power in Item 7 and Note 3 to the financial statements of Georgia Power under "Retail Regulatory Matters – Fuel Cost Recovery" in Item 8 of the Form 10-K for additional information.

On June 21, 2012, the Georgia PSC approved a 19% decrease in Georgia Power's fuel cost recovery rates, which reduced annual billings by $567 million effective June 1, 2012. The decrease in fuel costs resulted from lower natural gas prices as a result of increased natural gas supplies.

As of September 30, 2012, Georgia Power's fuel cost over recovery balance totaled $199 million. This balance is slightly below the $200 million required to automatically trigger the Georgia PSC's approved IFR adjustment mechanism. On November 1, 2012, Georgia Power filed a request with the Georgia PSC to reduce fuel cost recovery rates effective January 1, 2013 using the IFR process. The requested reduction would reduce annual billings by approximately $122 million. In accordance with the IFR process, the Georgia PSC will have 30 days to consider Georgia Power's request. The ultimate outcome of this matter cannot be determined at this time.

Fuel cost recovery revenues as recorded on the financial statements are adjusted for differences in actual recoverable fuel costs and amounts billed in current regulated rates. Accordingly, any changes in the billing factor will not have a significant effect on Georgia Power's revenues or net income, but will affect cash flow. See Note (B) to the Condensed Financial Statements under "Retail Regulatory Matters – Georgia Power – Fuel Cost Recovery" herein for additional information.

2011 Integrated Resource Plan Update

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality," " – Water Quality," and " – Coal Combustion Byproducts" of Georgia Power in Item 7 and Note 3 to the financial statements of Georgia Power under "Retail Regulatory Matters – Rate Plans" and " – 2011 Integrated Resource Plan Update" in Item 8 of the Form 10-K for additional information regarding proposed and final EPA rules and regulations, including the MATS rule for coal- and oil-fired electric utility steam generating units, revisions to effluent guidelines for steam electric power plants, and additional regulation of coal combustion byproducts; the State of Georgia's Multi-Pollutant Rule; Georgia Power's analysis of the potential costs and benefits of installing the required controls on its fossil generating units in light of these regulations; the 2010 ARP; and the 2011 IRP Update.

On March 20, 2012, the Georgia PSC approved Georgia Power's request to decertify and retire two coal-fired generation units at Plant Branch as of October 31, 2013 and December 31, 2013 and an oil-fired unit at Plant Mitchell as of March 26, 2012, which was included in Georgia Power's 2011 IRP Update. The Georgia PSC also approved three PPAs totaling 998 MWs with Southern Power for capacity and energy that will commence in 2015 and end in 2030. The PPAs remain subject to FERC approval. The ultimate outcome of this matter cannot be determined at this time.

Separately, on October 16, 2012, the Georgia PSC approved a 50 MW PPA with a Qualifying Facility for capacity and energy that will commence in 2015 and end in 2035.

Advanced Solar Initiative

Georgia Power filed a new solar initiative with the Georgia PSC on September 26, 2012. If approved, Georgia Power may acquire up to 210 MWs of additional solar capacity over a three-year period through long-term contracts. The ultimate outcome of this matter cannot be determined at this time.

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013), which will have a positive impact on the future cash flows of Georgia Power through 2013. Consequently, Georgia Power's positive cash flow benefit is estimated to be between $410 million and $460 million in 2012.

Construction

Nuclear

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Construction – Nuclear" of Georgia Power in Item 7 and Note 3 to the financial statements of Georgia Power under "Construction – Nuclear" in Item 8 of the Form 10-K for additional information regarding the construction of Plant Vogtle Units 3 and 4.

On February 16, 2012, a group of petitioners who had intervened in the NRC's combined construction and operating licenses (COLs) proceedings for Plant Vogtle Units 3 and 4 filed a petition in the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review and a stay of the NRC's issuance of the COLs. In addition, on February 16, 2012, another group of petitioners filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review of the NRC's certification of the Westinghouse Design Control Document, as amended (DCD). On April 3, 2012, the U.S. Court of Appeals for the District of Columbia Circuit granted a motion filed by these two groups of petitioners to consolidate their challenges. On April 18, 2012, another group of petitioners filed a motion to stay the effectiveness of the order issuing the COLs for Plant Vogtle Units 3 and 4 with the U.S. District Court for the District of Columbia. On July 11, 2012, the U.S. Court of Appeals for the District of Columbia Circuit denied the petitioners' motion to stay the effectiveness of the COLs. Georgia Power has intervened in and intends to vigorously contest these petitions.

In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4. In addition, the Georgia PSC voted to approve inclusion of the related CWIP accounts in rate base. Also in 2009, the Governor of the State of Georgia signed into law the Georgia Nuclear Energy Financing Act that allows Georgia Power to recover financing costs for nuclear construction projects by including the related CWIP accounts in rate base during the construction period. With respect to Plant Vogtle Units 3 and 4, this legislation allows Georgia Power to recover projected financing costs of approximately $1.7 billion during the construction period beginning in 2011, which reduces the projected in-service cost to approximately $4.4 billion. The Georgia PSC has ordered Georgia Power to report against this total certified cost of approximately $6.1 billion. On August 21, 2012, the Georgia PSC voted to approve Georgia Power's sixth semi-annual construction monitoring report including total costs of $2.0 billion for Plant Vogtle Units 3 and 4 incurred through December 31, 2011. Georgia Power will continue to file construction monitoring reports by February 28 and August 31 of each year during the construction period.

In addition, in December 2010, the Georgia PSC approved Georgia Power's NCCR tariff. The NCCR tariff became effective January 1, 2011 and adjustments are filed with the Georgia PSC on November 1 of each year to become effective on January 1 of the following year. On November 1, 2012, Georgia Power filed to increase the NCCR tariff by approximately $50 million effective January 1, 2013. Through the NCCR tariff, Georgia Power is collecting and amortizing to earnings approximately $91 million of financing costs, capitalized in 2009 and 2010, over the five-year period ending December 31, 2015, in addition to the ongoing financing costs. At September 30, 2012, approximately $59 million of these 2009 and 2010 costs remained in CWIP.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Georgia Power, Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and the City of Dalton, Georgia, an incorporated municipality in the State of Georgia acting by and through its Board of Water, Light, and Sinking Fund Commissioners (collectively, Owners) and Westinghouse and Stone & Webster, Inc. (collectively, Contractor) have established both informal and formal dispute resolution procedures in accordance with the engineering, procurement, and construction agreement for Plant Vogtle Units 3 and 4 (Vogtle 3 and 4 Agreement) in order to resolve issues arising during the course of constructing a project of this magnitude. The Contractor and Georgia Power (on behalf of the Owners) have successfully initiated both formal and informal claims through these procedures, including ongoing claims, to resolve disputes. When matters are not resolved through these procedures, the parties may proceed to litigation. The Contractor and the Owners are involved in litigation with respect to certain claims that have not been resolved through the formal dispute resolution process.

During the course of construction activities, issues have arisen that may impact the project budget and schedule. The most significant issues relate to costs associated with design changes to the DCD and costs associated with delays in the project schedule related to the timing of approval of the DCD and issuance of the COLs by the NRC. The Owners and the Contractor have begun negotiations regarding these issues, including the assertion by the Contractor that the Owners are responsible for these costs under the terms of the Vogtle 3 and 4 Agreement. Through correspondence sent to the Owners, the Contractor provided its proposed adjustment to the contract price and initiated the formal dispute resolution process. The Contractor's estimated adjustment attributable to Georgia Power (based on Georgia Power's ownership interest) is approximately $425 million (in 2008 dollars) with respect to these issues. Georgia Power has not agreed with the amount of these proposed adjustments or that the Owners have responsibility for any costs related to these issues. On November 1, 2012, Georgia Power and the other Owners filed suit against the Contractor in the U.S. District Court for the Southern District of Georgia, seeking a declaratory judgment that the Owners are not responsible for the costs related to these issues. Also on November 1, 2012, the Contractor filed suit against Georgia Power and the other Owners in the U.S. District Court for the District of Columbia, alleging the Owners are responsible for the costs related to these issues and seeking payment from the Owners of the full amount of these costs. While litigation has commenced, Georgia Power expects negotiations with the Contractor to continue with respect to cost and schedule during which time the parties will attempt to reach a mutually acceptable compromise of their positions. Georgia Power intends to vigorously defend its positions. If these costs ultimately are imposed upon the Owners, Georgia Power would seek an amendment to the certified cost of Plant Vogtle Units 3 and 4, if necessary. In connection with these negotiations, the Owners are evaluating whether maintaining the currently scheduled commercial operation dates of 2016 and 2017 remains in the best interest of their customers. Additional claims by the Contractor or Georgia Power (on behalf of the Owners) are expected to arise throughout the construction of Plant Vogtle Units 3 and 4.

In addition, there are processes in place that are designed to assure compliance with the design requirements specified in the DCD and the COLs, including rigorous inspection by Southern Nuclear and the NRC that occurs throughout construction. During a routine inspection in April 2012, the NRC identified that certain details of the rebar construction in the Plant Vogtle Unit 3 nuclear island were not consistent with the DCD. In May 2012, Southern Nuclear received an official notice of violation relating to these findings from the NRC. The design changes were determined to have minimal safety significance and, on October 18, 2012, the NRC approved a license amendment request to clarify that the nuclear island concrete and rebar construction will conform to NRC requirements. Various inspection and other issues are expected to arise from time to time as construction proceeds, which may result in additional license amendments or require other resolution.

There are pending technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4, including legal challenges to the NRC issuance of the COLs and certification of the DCD. Similar additional challenges at the state and federal level are expected as construction proceeds.

See RISK FACTORS of Georgia Power in Item 1A of the Form 10-K for a discussion of certain risks associated with the licensing, construction, and operation of nuclear generating units, including potential impacts that could result from a major incident at a nuclear facility anywhere in the world.

Plant McDonough Unit 1 was retired on February 29, 2012. Georgia Power placed Plant McDonough-Atkinson Unit 5 into service on April 26, 2012 and Plant McDonough-Atkinson Unit 6 into service on October 28, 2012.

Other Matters

Georgia Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Georgia Power is subject to certain claims and legal actions arising in the ordinary course of business. Georgia Power's business activities are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Georgia Power cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Georgia Power in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Georgia Power's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Other Matters" of Georgia Power in Item 7 of the Form 10-K for additional information regarding the earthquake and tsunami that struck Japan in March 2011. On March 12, 2012, the NRC issued three orders and a request for information based on the NRC task force report recommendations that included, among other items, additional mitigation strategies for beyond-design-basis events, enhanced spent fuel pool instrumentation capabilities, hardened vents for certain classes of containment structures, including the one in use at Plant Hatch, site specific evaluations for seismic and flooding hazards, and various plant evaluations to ensure adequate coping capabilities during station blackout and other conditions. On August 29, 2012, the NRC staff issued the final interim staff guidance document, which offers acceptable approaches to meeting the requirements of the NRC's orders before the December 31, 2016 compliance deadline. The interim staff guidance is not mandatory, but licensees would be required to obtain NRC approval for taking an approach other than as outlined in the interim staff guidance. The final form and the resulting impact of any changes to safety requirements for nuclear reactors will be dependent on further review and action by the NRC and cannot be determined at this time. See RISK FACTORS of Georgia Power in Item 1A of the Form 10-K for a discussion of certain risks associated with the licensing, construction, and operation of nuclear generating units, including potential impacts that could result from a major incident at a nuclear facility anywhere in the world. The ultimate outcome of these events cannot be determined at this time.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Georgia Power prepares its financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Georgia Power in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Georgia Power's results of operations

and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Georgia Power in Item 7 of the Form 10-K for a complete discussion of Georgia Power's critical accounting policies and estimates related to Electric Utility Regulation, Contingent Obligations, Unbilled Revenues, and Pension and Other Postretirement Benefits.

In March 2012, Georgia Power began using automated meter readings to measure unbilled KWH sales for energy delivered through month end. As of September 30, 2012, these measured unbilled KWH sales represent approximately 90% of total unbilled KWH sales. Increased usage of actual data to compute unbilled revenues reduces the impact that estimates could have on Georgia Power's results of operations; therefore, Georgia Power no longer considers unbilled revenue a critical accounting estimate.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" of Georgia Power in Item 7 of the Form 10-K for additional information. Georgia Power's financial condition remained stable at September 30, 2012. Georgia Power intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities," and "Capital Requirements and Contractual Obligations" herein for additional information.

Net cash provided from operating activities totaled $1.97 billion for the first nine months of 2012 compared to $2.08 billion for the corresponding period in 2011. The decrease was primarily due to lower retail operating revenues, higher fuel inventory additions in 2012, and lower deferred taxes due to the effect of bonus depreciation in 2011, partially offset by higher recovery of retail fuel costs. Net cash used for investing activities totaled $1.47 billion primarily related to the construction of Plant Vogtle Units 3 and 4 and Plant McDonough-Atkinson Units 5 and 6. Net cash used for financing activities totaled $92 million for the first nine months of 2012 compared to $732 million used for financing activities in the corresponding period in 2011. The decrease is primarily due to increased debt issuances in 2012 to support the ongoing construction program. Fluctuations in cash flow from financing activities vary from year to year based on capital needs and the maturity or redemption of securities.

Significant balance sheet changes for the first nine months of 2012 include increases of $701 million in total property, plant, and equipment, $590 million in debt, and $412 million in cash and cash equivalents, as well as a $336 million change in under/over recovered fuel.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Georgia Power in Item 7 of the Form 10-K for a description of Georgia Power's capital requirements for its construction program, including estimated capital expenditures to comply with existing environmental regulations, scheduled maturities of long-term debt, as well as related interest, derivative obligations, preferred and preference stock dividends, leases, purchase commitments, trust funding requirements, and unrecognized tax benefits. Approximately $1.46 billion will be required through September 30, 2013 to fund maturities of long-term debt.

See FUTURE EARNINGS POTENTIAL – "Environmental Statutes and Regulations – General" herein for a description of Georgia Power's estimated capital expenditures to comply with the MATS rule and proposed water and coal combustion byproducts rules.

81

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The construction program is subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; changes in environmental statutes and regulations; the outcome of any legal challenges to the environmental rules; changes in generating plants, including unit retirements and replacements and adding or changing fuel sources at existing units, to meet new regulatory requirements; changes in FERC rules and regulations; Georgia PSC approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; storm impacts; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.

On March 20, 2012, the Georgia PSC approved three PPAs totaling 998 MWs with Southern Power for capacity and energy that will commence in 2015 and end in 2030. However, these PPAs remain subject to FERC approval. See FUTURE EARNINGS POTENTIAL – "PSC Matters – 2011 Integrated Resource Plan Update" herein for additional information. On October 16, 2012, the Georgia PSC approved a 50 MW PPA with a Qualifying Facility for capacity and energy that will commence in 2015 and end in 2035. These four PPAs will be accounted for as operating leases and are expected to result in additional obligations of approximately $69 million in 2015, $82 million in 2016, and a total of $1.35 billion thereafter. The ultimate outcome of this matter cannot be determined at this time.

Sources of Capital

Except as described below with respect to potential DOE loan guarantees, Georgia Power plans to obtain the funds required for construction and other purposes from sources similar to those used in the past, which were primarily from operating cash flows, short-term debt, security issuances, term loans, and equity contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend upon regulatory approval, prevailing market conditions, and other factors. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Georgia Power in Item 7 of the Form 10-K for additional information.

In June 2010, Georgia Power reached an agreement with the DOE to accept terms for a conditional commitment for federal loan guarantees that would apply to future borrowings by Georgia Power related to the construction of Plant Vogtle Units 3 and 4. Any borrowings guaranteed by the DOE would be full recourse to Georgia Power and secured by a first priority lien on Georgia Power's 45.7% undivided ownership interest in Plant Vogtle Units 3 and 4. Total guaranteed borrowings would not exceed the lesser of 70% of eligible project costs, or approximately $3.46 billion, and are expected to be funded by the Federal Financing Bank. Final approval and issuance of loan guarantees by the DOE are subject to negotiation of definitive agreements, completion of due diligence by the DOE, receipt of any necessary regulatory approvals, and satisfaction of other conditions. In the event that the DOE does not issue a loan guarantee or Georgia Power determines that the final terms and conditions of the loan guarantee by the DOE are not in the best interest of its customers, Georgia Power expects to finance the construction of Plant Vogtle Units 3 and 4 through traditional capital markets financings. There can be no assurance that the DOE will issue loan guarantees for Georgia Power. See FUTURE EARNINGS POTENTIAL – "Construction – Nuclear" herein for more information on Plant Vogtle Units 3 and 4.

Georgia Power's current liabilities frequently exceed current assets because of the continued use of short-term debt as a funding source to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate significantly due to the seasonality of the business.

82

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

At September 30, 2012, Georgia Power had approximately $425 million of cash and cash equivalents. Committed credit arrangements with banks at September 30, 2012, including expiration dates, were as follows:

Expires										Executable Term Loans				Due Within One Year(a)
2012		2013		2014 and Beyond		Total		Unused		One Year		Two Years		Term Out		No Term Out
(in millions)						(in millions)				(in millions)				(in millions)
$	—	$	—	$	1,750	$	1,750	$	1,740	$	—	$	—	$	—	$	—

(a) Reflects facilities expiring on or before September 30, 2013.

See Note 6 to the financial statements of Georgia Power under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Most of these arrangements contain covenants that limit debt levels and typically contain cross default provisions that are restricted only to the indebtedness of Georgia Power. Georgia Power is currently in compliance with all such covenants. Georgia Power expects to renew its credit arrangements, as needed, prior to expiration. These credit arrangements provide liquidity support to Georgia Power's commercial paper borrowings and variable rate pollution control revenue bonds. The amount of variable rate pollution control revenue bonds outstanding requiring liquidity support as of September 30, 2012 was approximately $868 million.

Georgia Power may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell commercial paper at the request and for the benefit of Georgia Power and the other traditional operating companies. Proceeds from such issuances for the benefit of Georgia Power are loaned directly to Georgia Power. The obligations of each traditional operating company under these arrangements are several and there is no cross affiliate credit support.

During the three months ended September 30, 2012, Georgia Power had no commercial paper or other short-term debt outstanding.

Management believes that the need for working capital can be adequately met by utilizing commercial paper programs, lines of credit, and cash.

Credit Rating Risk

Georgia Power does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to BBB- and/or Baa3 or below. These contracts are for physical electricity purchases and sales, fuel purchases, fuel transportation and storage, energy price risk management, and construction of new generation. The maximum potential collateral requirements under these contracts at September 30, 2012 were as follows:

Credit Ratings	Maximum Potential Collateral Requirements
	(in millions)
At BBB- and/or Baa3	$	65
Below BBB- and/or Baa3	1,296

83

GEORGIA POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, any credit rating downgrade could impact Georgia Power's ability to access capital markets, particularly the short-term debt market.

Market Price Risk

Georgia Power's market risk exposure relative to interest rate changes for the third quarter 2012 has not changed materially compared with the December 31, 2011 reporting period. Since a significant portion of outstanding indebtedness is at fixed rates, Georgia Power is not aware of any facts or circumstances that would significantly affect exposures on existing indebtedness in the near term. However, the impact on future financing costs cannot now be determined.

Due to cost-based rate regulation and other various cost recovery mechanisms, Georgia Power continues to have limited exposure to market volatility in interest rates, commodity fuel prices, and prices of electricity. To mitigate residual risks relative to movements in electricity prices, Georgia Power enters into physical fixed-price contracts for the purchase and sale of electricity through the wholesale electricity market and, to a lesser extent, financial hedge contracts for natural gas purchases. Georgia Power continues to manage a fuel-hedging program implemented per the guidelines of the Georgia PSC. As such, Georgia Power had no material change in market risk exposure for the third quarter 2012 relative to fuel and electricity prices when compared with the December 31, 2011 reporting period.

The changes in fair value of energy-related derivative contracts, substantially all of which are composed of regulatory hedges, for the three and nine months ended September 30, 2012 were as follows: 

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(58	)	$	(82	)
Contracts realized or settled	18			63
Current period changes(a)	13			(8		)
Contracts outstanding at the end of the period, assets (liabilities), net	$	(27	)	$	(27	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

The changes in the fair value positions of the energy-related derivative contracts, which are substantially all attributable to both the volume and the price of natural gas, for the three and nine months ended September 30, 2012 were as follows: 

	Third Quarter 2012 Changes		Year-to-Date 2012 Changes

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The net hedge volumes of energy-related derivative contracts were as follows: 

	September 30, 2012	June 30, 2012	December 31, 2011
	mmBtu Volume
	(in millions)
Commodity – Natural gas swaps	17	23	29
Commodity – Natural gas options	90	73	44
Total hedge volume	107	96	73

The weighted average swap contract cost above market prices was approximately $0.88 per mmBtu as of September 30, 2012, $1.37 per mmBtu as of June 30, 2012, and $1.65 per mmBtu as of December 31, 2011. The change in option premiums is primarily attributable to the volatility of the market and the underlying change in the natural gas price. All natural gas hedge gains and losses are recovered through Georgia Power's fuel cost recovery mechanism.

Regulatory hedges relate to Georgia Power's fuel-hedging program where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through Georgia Power's fuel cost recovery mechanism.

Unrealized pre-tax gains and losses recognized in income for the three and nine months ended September 30, 2012 and 2011 for energy-related derivative contracts that are not hedges were not material.

Georgia Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows: 

	September 30, 2012 Fair Value Measurements
	Total			Maturity
	Fair Value			Year 1			Years 2&3
				(in millions)
Level 1	$	—		$	—		$	—
Level 2	(27		)	(22		)	(5		)
Level 3	—			—			—
Fair value of contracts outstanding at end of period	$	(27	)	$	(22	)	$	(5	)

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Georgia Power. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Georgia Power and its derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Georgia Power does not expect the impact of these rules to be material.

The net proceeds from the sale of the Series 2012B Senior Notes, together with the net proceeds from the sale of the Series 2012A Senior Notes, were used to repay a portion of Georgia Power's short-term debt and bank loans, for the redemption in July 2012 of $300 million aggregate principal amount of Georgia Power's Series 2007D 6.375% Senior Notes due July 15, 2047, and for general corporate purposes, including Georgia Power's continuous construction program.

In May 2012, the Development Authority of Monroe County issued $48.72 million aggregate principal amount of Pollution Control Revenue Bonds (Georgia Power Company Plant Scherer Project), First Series 2012 for the benefit of Georgia Power. The proceeds were used in June 2012 to redeem $48.72 million aggregate principal amount of Development Authority of Monroe County Pollution Control Revenue Bonds (Georgia Power Company Plant Scherer Project), First Series 2006.

In June 2012, the Development Authority of Burke County issued $85 million aggregate principal amount of Pollution Control Revenue Bonds (Georgia Power Company Plant Vogtle Project), First Series 2012 and $100 million aggregate principal amount of Pollution Control Revenue Bonds (Georgia Power Company Plant Vogtle Project), Second Series 2012 for the benefit of Georgia Power. The proceeds were used in July 2012 to redeem $85 million aggregate principal amount of Development Authority of Burke County (Georgia) Pollution Control Revenue Bonds (Georgia Power Company Plant Vogtle Project), First Series 2005 and $100 million aggregate principal amount of Development Authority of Burke County (Georgia) Pollution Control Revenue Bonds (Georgia Power Company Plant Vogtle Project), Second Series 2005.

In August 2012, Georgia Power issued $400 million aggregate principal amount of Series 2012C 0.75% Senior Notes due August 10, 2015.

Subsequent to September 30, 2012, Georgia Power announced the redemption that will occur in December 2012 of $100 million aggregate principal amount of its Series 2007F 6.05% Senior Monthly Notes due December 1, 2038.

In addition to any financings that may be necessary to meet capital requirements and contractual obligations, Georgia Power plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-cost capital if market conditions permit.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Gulf Power operates as a vertically integrated utility providing electricity to retail customers within its traditional service territory located in northwest Florida and to wholesale customers in the Southeast. Many factors affect the opportunities, challenges, and risks of Gulf Power's business of selling electricity. These factors include the ability to maintain a constructive regulatory environment, to maintain and grow energy sales given economic conditions, and to effectively manage and secure timely recovery of costs. These costs include those related to projected long-term demand growth, increasingly stringent environmental standards, reliability, fuel prices, and storm restoration following major storms. Appropriately balancing required costs and capital expenditures with customer prices will continue to challenge Gulf Power for the foreseeable future.

On March 12, 2012, the Florida PSC approved a permanent increase in retail base rates and charges of $64 million effective April 11, 2012. The amount of the permanent increase includes the previously approved $38.5 million interim retail rate increase implemented in September 2011. The Florida PSC's decision on the amount of the permanent increase also included a determination that none of the base rate revenues collected on an interim basis would be refunded. Gulf Power's authorized retail ROE is a range of 9.25% to 11.25% with new retail base rates set at the midpoint retail ROE of 10.25%. In addition, the Florida PSC also approved a step increase to Gulf Power's retail base rates and charges of $4 million to be effective in January 2013.

Gulf Power continues to focus on several key performance indicators. These indicators include customer satisfaction, plant availability, system reliability, and net income after dividends on preference stock. For additional information on these indicators, see MANAGEMENT'S DISCUSSION AND ANALYSIS – OVERVIEW – "Key Performance Indicators" of Gulf Power in Item 7 of the Form 10-K.

RESULTS OF OPERATIONS

Net Income

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$6.5	15.9	$17.1	19.9

Gulf Power's net income after dividends on preference stock for the third quarter 2012 was $47.7 million compared to $41.2 million for the corresponding period in 2011. The increase was primarily due to higher revenues due to increases in retail base rates, partially offset by milder weather in 2012 and a decrease in retail energy sales in 2012 due to a decrease in customer usage.

Gulf Power's net income after dividends on preference stock for year-to-date 2012 was $103.4 million compared to $86.3 million for the corresponding period in 2011. The increase was primarily due to higher revenues due to increases in retail base rates and higher wholesale capacity revenues from non-affiliates in 2012. These increases were partially offset by milder weather in 2012 and a decrease in retail energy sales in 2012 due to a decrease in customer usage.

(change in millions)	(% change)	(change in millions)	(% change)

In the third quarter 2012, retail revenues were $347.4 million compared to $362.1 million for the corresponding period in 2011. For year-to-date 2012, retail revenues were $880.8 million compared to $957.4 million for the corresponding period in 2011.

Details of the change to retail revenues were as follows:

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters" of Gulf Power in Item 7 and Note 1 to the financial statements of Gulf Power under "Revenues" and Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters" in Item 8 of the Form 10-K for additional information regarding Gulf Power's retail base rate case and cost recovery clauses, including Gulf Power's fuel cost recovery, purchased power capacity recovery, environmental cost recovery, and energy conservation cost recovery clauses.

Revenues associated with changes in rates and pricing increased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to higher revenues due to increases in retail base rates and revenues associated with higher recoverable costs under Gulf Power's energy conservation cost recovery clause, partially offset by a decrease in revenues associated with lower recoverable costs under Gulf Power's environmental cost recovery clause.

Revenues attributable to changes in sales decreased in the third quarter 2012 when compared to the corresponding period in 2011. Weather-adjusted KWH energy sales to residential and commercial customers decreased 2.1% and 0.3%, respectively, primarily due to lower use per customer. KWH energy sales to industrial customers decreased 4.2% primarily due to a billing adjustment recorded in July 2011, partially offset by an increase in sales due to decreased customer co-generation and changes in customer production levels.

Revenues attributable to changes in sales decreased year-to-date 2012 when compared to the corresponding period in 2011. Weather-adjusted KWH energy sales to residential and commercial customers decreased 1.9% and 1.3%, respectively, due to lower use per customer. KWH energy sales to industrial customers decreased 6.6% primarily due to increased customer co-generation due to the lower cost of natural gas in 2012 and changes in customer production levels.

Revenues attributable to changes in weather decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 due to milder weather in 2012.

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Fuel and other cost recovery revenues decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to lower costs due to lower natural gas prices and decreased KWH energy sales. Fuel and other cost recovery provisions include fuel expenses, the energy component of purchased power costs, purchased power capacity costs, and the difference between projected and actual costs and revenues related to energy conservation and environmental compliance. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Cost Recovery Clauses – Fuel Cost Recovery" herein for additional information.

Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy compared to the cost of Gulf Power's and the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation. Wholesale revenues from non-affiliates include unit power sales under long-term contracts to other utilities in Florida and Georgia. Wholesale revenues from these contracts have both capacity and energy components. Capacity revenues reflect the recovery of fixed costs and a return on investment under the contracts. Energy is generally sold at variable cost.

In the third quarter 2012, wholesale revenues from non-affiliates were $27.4 million compared to $33.9 million for the corresponding period in 2011. The decrease was primarily due to lower energy revenues related to a 43.1% decrease in KWH sales as a result of less energy scheduled by unit power customers due to their use of lower cost generation resources to serve their loads. The decrease was partially offset by an 8.0% increase in capacity revenues related to higher capacity rates resulting from change-in-law contract provisions that provide for recovery of costs related to the generating resource's compliance with new environmental requirements.

For year-to-date 2012, wholesale revenues from non-affiliates were $83.3 million compared to $103.8 million for the corresponding period in 2011. The decrease was primarily due to lower energy revenues related to a 51.3% decrease in KWH sales as a result of less energy scheduled by unit power customers due to their use of lower cost generation resources to serve their loads. The decrease was partially offset by a 12.4% increase in capacity revenues related to higher capacity rates resulting from change-in-law contract provisions that provide for recovery of costs related to the generating resource's compliance with new environmental requirements.

Wholesale revenues from sales to affiliated companies within the Southern Company system will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since the fuel revenue related to energy sales and the cost of energy purchases are both included in the determination of recoverable fuel costs and are generally offset by revenues collected in Gulf Power's fuel cost recovery clause.

In the third quarter 2012, wholesale revenues from affiliates were $30.1 million compared to $52.8 million for the corresponding period in 2011. The decrease was primarily due to lower energy revenues related to a 19.7% decrease in KWH sales to serve affiliate demand, primarily resulting from milder weather in the third quarter 2012 compared to the corresponding period in 2011, and a 29.0% decrease in the price of energy in the third quarter 2012.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For year-to-date 2012, wholesale revenues from affiliates were $95.2 million compared to $79.8 million for the corresponding period in 2011. The increase was primarily due to higher energy revenues related to a 99.1% increase in KWH sales resulting from the availability of Gulf Power's lower priced generation resources to serve affiliate demand. The increase was partially offset by a 40.1% decrease in the price of energy for year-to-date 2012.

In the third quarter 2012, total fuel and purchased power expenses were $189.9 million compared to $250.3 million for the corresponding period in 2011. The decrease in fuel and purchased power expenses was primarily due to a $29.3 million decrease in the average cost of fuel and purchased power and a $43.5 million decrease related to the volume of KWHs generated. The decrease was partially offset by a $12.4 million increase related to the volume of KWHs purchased.

For year-to-date 2012, total fuel and purchased power expenses were $483.3 million compared to $607.8 million for the corresponding period in 2011. The decrease in fuel and purchased power expenses was primarily due to a $136.0 million decrease in the average cost of fuel and purchased power and a $96.7 million decrease related to the volume of KWHs generated. The decrease was partially offset by a $108.2 million increase related to the volume of KWHs purchased.

Fuel and purchased power transactions do not have a significant impact on earnings since energy and capacity expenses are generally offset by energy and capacity revenues through Gulf Power's fuel cost and purchased power capacity recovery clauses. See FUTURE EARNINGS POTENTIAL – "PSC Matters – Cost Recovery Clauses – Fuel Cost Recovery" and "– Purchased Power Capacity Recovery" herein for additional information.

Fuel

In the third quarter 2012, fuel expense was $160.8 million compared to $220.3 million for the corresponding period in 2011. The decrease was primarily due to a higher utilization of lower cost natural gas-fired sources, a 0.7% decrease in the average cost of natural gas per KWH generated, and a 25.2% decrease in KWHs generated as a result of displacement of coal-fired generation by energy purchases and lower demand related to milder weather in 2012. These decreases were partially offset by a 15.2% increase in KWHs purchased.

For year-to-date 2012, fuel expense was $423.1 million compared to $530.8 million for the corresponding period in 2011. The decrease was primarily due to a higher utilization of lower cost natural gas-fired sources, a 6.3% decrease in the average cost of natural gas per KWH generated, and a 20.2% decrease in KWHs generated as a result of displacement of coal-fired generation by energy purchases and lower demand related to milder weather and decreased customer usage in 2012. These decreases were partially offset by a 71.3% increase in KWHs purchased.

In the third quarter and year-to-date 2012, the decrease in the average cost of fuel was a result of decreases in the average costs of natural gas and coal per KWH generated and a higher percentage of utilization of Gulf Power's lower cost natural gas-fired generation sources.

Purchased Power – Non-Affiliates

In the third quarter 2012, purchased power expense from non-affiliates was $18.3 million compared to $20.0 million for the corresponding period in 2011. The decrease was due to decreases of $1.5 million in energy costs and $0.2 million in capacity costs. The decrease in energy costs resulted from lower average cost per KWH purchased, partially offset by an increase in the volume of KWHs purchased.

For year-to-date 2012, purchased power expense from non-affiliates was $41.7 million compared to $37.9 million for the corresponding period in 2011. The increase was due to a $3.9 million increase in energy costs, partially offset by a $0.1 million decrease in capacity costs. The increase in energy costs was due to an increase in the volume of KWHs purchased, partially offset by lower average cost per KWH.

Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation.

Purchased Power – Affiliates

In the third quarter 2012, purchased power expense from affiliates was $10.8 million compared to $10.0 million for the corresponding period in 2011. The increase was due to increases of $0.6 million in energy costs and $0.2 million in capacity costs. The increase in energy costs was due to an increase in the volume of KWHs purchased, partially offset by a lower average cost per KWH purchased.

For year-to-date 2012, purchased power expense from affiliates was $18.5 million compared to $39.1 million for the corresponding period in 2011. The decrease was due to a decrease of $20.9 million in energy costs, partially offset by a $0.3 million increase in capacity costs. The decrease in energy costs was due to a decrease in the volume of KWHs purchased and a lower average cost per KWH purchased.

Energy purchases from affiliates will vary depending on demand and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other contractual agreements, all as approved by the FERC.

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Gulf Power's future earnings potential. The level of Gulf Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Gulf Power's business of selling electricity. These factors include Gulf Power's ability to maintain a constructive regulatory environment that continues to allow for the timely recovery of prudently incurred costs during a time of increasing costs. Future earnings in the near term will depend, in part, upon maintaining energy sales which is subject to a number of factors. These factors include weather, competition, new energy contracts with neighboring utilities, energy conservation practiced by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or decline in Gulf Power's service territory. Changes in economic conditions impact sales for Gulf Power, and the pace of the economic recovery remains uncertain. The timing and extent of the economic recovery will impact growth and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Gulf Power in Item 7 of the Form 10-K.

Environmental Matters

Compliance costs related to federal and state environmental statutes and regulations could affect earnings if such costs cannot continue to be fully recovered in rates on a timely basis. Environmental compliance spending over the next several years may differ materially from the amounts estimated. The timing, specific requirements, and estimated costs could change as environmental statutes and regulations are adopted or modified. Further, higher costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could negatively affect results of operations, cash flows, and financial condition.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – General" of Gulf Power in Item 7 of the Form 10-K for information regarding Gulf Power's estimated base level capital expenditures to comply with existing statutes and regulations for 2012 through 2014, as well as Gulf Power's preliminary estimates for potential incremental environmental compliance investments associated with complying with the EPA's final Mercury and Air Toxics Standards (MATS) rule (formerly referred to as the Utility Maximum Achievable Control Technology rule) and the EPA's proposed water and coal combustion byproducts rules.

99

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Gulf Power is continuing to develop its compliance strategy and to assess the potential costs of complying with the MATS rule and the EPA's proposed water and coal combustion byproducts rules. While the final MATS compliance plan is still being developed and the ultimate costs remain uncertain, compliance decisions made in 2012 have allowed Gulf Power to further develop its cost estimates for compliance with the MATS rule. As a result, estimated compliance costs for the MATS rule in the 2012 through 2014 period have been revised from up to $375 million to up to $205 million as follows: 

	2012	2013	2014
		(in millions)
MATS rule	—	Up to $55	Up to $150

In addition, Gulf Power has further developed its estimated capital expenditures and associated timing of these expenditures to comply with the proposed water and coal combustion byproducts rules, resulting in a reduction, due primarily to timing, in estimated compliance costs for 2012 through 2014. Potential incremental environmental compliance investments to comply with the proposed water and coal combustion byproducts rules have been revised from up to $105 million to up to $35 million over the 2012 through 2014 period, based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule. These potential incremental environmental compliance investments are estimated as follows: 

	2012	2013	2014
		(in millions)
Proposed water and coal combustion byproducts rules	—	Up to $10	Up to $25

While Gulf Power's ultimate costs of compliance with the MATS rule and the proposed water and coal combustion byproducts rules remain uncertain, Gulf Power estimates that compliance costs through 2021 (assuming that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) could be approximately $1.3 billion. Included in this amount is approximately $400 million that is also included in the 2012 through 2014 base level capital investment of Gulf Power described in the Form 10-K in anticipation of these rules.

Gulf Power's ultimate compliance strategy and actual future environmental capital expenditures are dependent on development of the final MATS compliance plan and will be affected by the final requirements of new or revised environmental regulations that are promulgated; the outcome of any legal challenges to the environmental rules; the cost, availability, and existing inventory of emissions allowances; and Gulf Power's fuel mix. Compliance costs may arise from retirement and replacement of existing units, installation of additional environmental controls, upgrades to the transmission system, and changing fuel sources for certain existing units. The ultimate outcome of these matters cannot be determined at this time.

Air Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality" of Gulf Power in Item 7 of the Form 10-K for additional information on the eight-hour ozone and fine particulate matter air quality standards, the MATS rule, the Cross-State Air Pollution Rule (CSAPR), and the Clean Air Visibility Rule (CAVR).

On May 21, 2012, the EPA published its final determination of nonattainment areas based on the 2008 eight-hour ozone air quality standards. None of the areas within Gulf Power's service territory were designated as nonattainment areas.

100

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

On June 14, 2012, the EPA proposed a rule that would increase the stringency of the fine particulate matter national ambient air quality standards. If adopted, the proposed standards could result in the designation of new nonattainment areas within Gulf Power's service territory. As part of a related settlement, the EPA has agreed to finalize the proposed rule by December 14, 2012. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Numerous petitions for administrative reconsideration of the MATS rule, including a petition by Southern Company and its subsidiaries, including Gulf Power, have been filed with the EPA. Challenges to the final rule have also been filed in the U.S. District Court for the District of Columbia by numerous states, environmental organizations, industry groups, and others. The impact of the MATS rule will depend on the outcome of these and any other legal challenges and, therefore, cannot be determined at this time.

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR in its entirety and directed the EPA to continue to administer the Clean Air Interstate Rule pending the EPA's development of a valid replacement. The vacatur of CSAPR creates additional uncertainty with respect to whether additional controls may be required for CAVR and best available retrofit technology compliance. On October 5, 2012, the EPA filed for review of the decision by the U.S. Court of Appeals for the District of Columbia Circuit. The ultimate outcome of this matter depends on the outcome of any legal challenges and further action by the EPA and cannot be determined at this time.

On August 29, 2012, the EPA published proposed revisions to the New Source Performance Standard (NSPS) for Stationary Combustion Turbines (CTs). If finalized, the revisions would apply the NSPS to all new, reconstructed, and modified CTs, including CTs at combined cycle units, during all periods of operation, including startup and shutdown, and alter the criteria for determining when an existing CT has been reconstructed. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Water Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Water Quality" of Gulf Power in Item 7 of the Form 10-K for additional information on the proposed rules regarding certain cooling water intake structures. The EPA has entered into an amended settlement agreement to extend the deadline for issuing a final rule until June 27, 2013. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Coal Combustion Byproducts

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Coal Combustion Byproducts" of Gulf Power in Item 7 of the Form 10-K for additional information. Environmental groups and other parties have filed lawsuits in the U.S. District Court for the District of Columbia seeking to require the EPA to complete its rulemaking process and issue final regulations pertaining to the regulation of coal combustion byproducts.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Gulf Power in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

PSC Matters

Retail Base Rate Case

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Retail Base Rate Case" of Gulf Power in Item 7 and Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Retail Base Rate Case" in Item 8 of the Form 10-K for additional information.

On March 12, 2012, the Florida PSC approved a permanent increase in retail base rates and charges of $64 million effective April 11, 2012. The amount of the permanent increase includes the previously approved $38.5 million interim retail rate increase implemented in September 2011. The Florida PSC's decision on the amount of the permanent increase also included a determination that none of the base rate revenues collected on an interim basis would be refunded. Gulf Power's authorized retail ROE is a range of 9.25% to 11.25% with new retail base rates set at the midpoint retail ROE of 10.25%. In addition, the Florida PSC also approved a step increase to Gulf Power's retail base rates and charges of $4 million to be effective in January 2013.

At December 31, 2011, the over recovered purchased power capacity costs totaled $8.0 million, which is included in other regulatory liabilities, current on Gulf Power's Condensed Balance Sheets herein.

Environmental Cost Recovery

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Environmental Cost Recovery" of Gulf Power in Item 7 and Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Environmental Cost Recovery" in Item 8 of the Form 10-K for additional information.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a flue gas desulfurization system (scrubber) on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court of Harrison County, Mississippi. These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, excluding AFUDC, and it is scheduled for completion in December 2015. Gulf Power's portion of the cost is expected to be recovered through the environmental cost recovery clause. The ultimate outcome of this matter cannot be determined at this time.

Over recovered environmental costs at September 30, 2012 totaled $6.9 million compared to $10.0 million at December 31, 2011. These amounts are included in other regulatory liabilities, current on Gulf Power's Condensed Balance Sheets herein.

Energy Conservation Cost Recovery

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Energy Conservation Cost Recovery" of Gulf Power in Item 7 and Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Energy Conservation Cost Recovery" in Item 8 of the Form 10-K for additional information.

Under recovered energy conservation costs at September 30, 2012 totaled $0.2 million compared to $3.1 million at December 31, 2011. These amounts are included in under recovered regulatory clause revenues on Gulf Power's Condensed Balance Sheets herein.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013), which will have a positive impact on the future cash flows of Gulf Power through 2013. Consequently, Gulf Power's positive cash flow benefit is estimated to be between $135 million and $150 million in 2012.

Other Matters

Gulf Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Gulf Power is subject to certain claims and legal actions arising in the ordinary course of business. Gulf Power's business activities are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Gulf Power cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Gulf Power in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Gulf Power's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Gulf Power prepares its financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Gulf Power in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Gulf Power's results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Gulf Power in Item 7 of the Form 10-K for a complete discussion of Gulf Power's critical accounting policies and estimates related to Electric Utility Regulation, Contingent Obligations, Unbilled Revenues, and Pension and Other Postretirement Benefits.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" of Gulf Power in Item 7 of the Form 10-K for additional information. Gulf Power's financial condition remained stable at September 30, 2012. Gulf Power intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities," and "Capital Requirements and Contractual Obligations" herein for additional information.

104

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Net cash provided from operating activities totaled $405.8 million for the first nine months of 2012 compared to $325.3 million for the corresponding period in 2011. The $80.5 million increase was primarily due to a $75.5 million increase in deferred income taxes primarily related to bonus depreciation. Net cash used for investing activities totaled $266.7 million in the first nine months of 2012 primarily due to property additions to utility plant and costs of removal. Net cash used for financing activities totaled $133.5 million for the first nine months of 2012. This was primarily due to short-term debt payments, long-term debt redemptions, and payment of common stock dividends, partially offset by common stock and long-term debt issuances. Fluctuations in cash flow from financing activities vary from year to year based on capital needs and the maturity or redemption of securities.

Significant balance sheet changes for the first nine months of 2012 include a net increase of $169.7 million in property, plant, and equipment, primarily due to the addition of environmental control projects, an increase of $157.1 million in accumulated deferred income taxes, primarily related to bonus depreciation, an increase of $60.0 million in securities due within one year, an increase in common stock, without par value due to the issuance of common stock to Southern Company for $40 million, and a decrease of $95.3 million in notes payable primarily reduced by funds from operating activities and long-term debt.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Gulf Power in Item 7 of the Form 10-K for a description of Gulf Power's capital requirements for its construction program, including estimated capital expenditures to comply with existing environmental regulations, scheduled maturities of long-term debt, as well as the related interest, leases, derivative obligations, preference stock dividends, purchase commitments, trust funding requirements, and unrecognized tax benefits. Approximately $60 million will be required through September 30, 2013 to fund maturities of long-term debt.

See FUTURE EARNINGS POTENTIAL – "Environmental Statutes and Regulations – General" herein for a description of Gulf Power's estimated capital expenditures to comply with the MATS rule and proposed water and coal combustion byproducts rules.

The construction program is subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; storm impacts; changes in environmental statutes and regulations; the outcome of any legal challenges to the environmental rules; changes in generating plants, including unit retirements and replacements and adding or changing fuel sources at existing units, to meet new regulatory requirements; changes in FERC rules and regulations; Florida PSC approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.

Sources of Capital

Gulf Power plans to obtain the funds required for construction and other purposes from sources similar to those used in the past, which were primarily from operating cash flows, short-term debt, security issuances, term loans, and equity contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend upon regulatory approval, prevailing market conditions, and other factors. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Gulf Power in Item 7 of the Form 10-K for additional information.

Gulf Power's current liabilities frequently exceed current assets because of the continued use of short-term debt as a funding source to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate significantly due to the seasonality of the business.

105

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

At September 30, 2012, Gulf Power had approximately $22.9 million of cash and cash equivalents. Committed credit arrangements with banks at September 30, 2012, including expiration dates, were as follows:

Expires										Executable Term Loans			Due Within One Year(a)
2012		2013		2014		Total		Unused		One     Year		Two     Years	Term     Out		No Term Out
(in millions)						(in millions)				(in millions)			(in millions)
$	20	$	60	$	195	$	275	$	275	$	45	—	$	45	$	35

(a) Reflects facilities expiring on or before September 30, 2013.

See Note 6 to the financial statements of Gulf Power under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Most of these arrangements contain covenants that limit debt levels and typically contain cross default provisions that are restricted only to the indebtedness of Gulf Power. Gulf Power is currently in compliance with all such covenants. Gulf Power expects to renew its credit arrangements, as needed, prior to expiration. These credit arrangements provide liquidity support to Gulf Power's commercial paper borrowings and variable rate pollution control revenue bonds. The amount of variable rate pollution control revenue bonds outstanding requiring liquidity support as of September 30, 2012 was approximately $69 million.

Gulf Power may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell commercial paper at the request and for the benefit of Gulf Power and the other traditional operating companies. Proceeds from such issuances for the benefit of Gulf Power are loaned directly to Gulf Power. The obligations of each traditional operating company under these arrangements are several and there is no cross affiliate credit support.

Details of short-term borrowings were as follows: 

	Short-term Debt at September 30, 2012				Short-term Debt During the Period(a)
	Amount Outstanding		Weighted Average Interest Rate		Average Outstanding		Weighted Average Interest Rate		Maximum Amount Outstanding
	(in millions)				(in millions)				(in millions)
Commercial paper	$	16	0.3	%	$	82	0.3	%	$	118

(a) Average and maximum amounts are based upon daily balances during the three month period ended September 30, 2012.

Management believes that the need for working capital can be adequately met by utilizing the commercial paper program, lines of credit, and cash.

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Credit Rating Risk

Gulf Power does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to BBB- and/or Baa3 or below. These contracts are for physical electricity purchases and sales, fuel transportation and storage, and energy price risk management. The maximum potential collateral requirements under these contracts at September 30, 2012 were as follows:

Credit Ratings	Maximum Potential Collateral Requirements
	(in millions)
At BBB- and/or Baa3	$	117
Below BBB- and/or Baa3	502

Included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, any credit rating downgrade could impact Gulf Power's ability to access capital markets, particularly the short-term debt market.

Market Price Risk

Gulf Power's market risk exposure relative to interest rate changes for the third quarter 2012 has not changed materially compared with the December 31, 2011 reporting period. Since a significant portion of outstanding indebtedness is at fixed rates, Gulf Power is not aware of any facts or circumstances that would significantly affect exposures on existing indebtedness in the near term. However, the impact on future financing costs cannot now be determined.

Due to cost-based rate regulation and other various cost recovery mechanisms, Gulf Power continues to have limited exposure to market volatility in interest rates, commodity fuel prices, and prices of electricity. Gulf Power continues to manage a financial hedging program for fuel purchased to operate its electric generating fleet implemented per the guidelines of the Florida PSC. As such, Gulf Power had no material change in market risk exposure for the third quarter 2012 when compared with the December 31, 2011 reporting period.

The changes in fair value of energy-related derivative contracts, substantially all of which are composed of regulatory hedges, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(37	)	$	(41	)
Contracts realized or settled	8			27
Current period changes(a)	16			1
Contracts outstanding at the end of the period, assets (liabilities), net	$	(13	)	$	(13	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

107

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The changes in the fair value positions of the energy-related derivative contracts, which are substantially all attributable to both the volume and the price of natural gas, for the three and nine months ended September 30, 2012 were as follows: 

	Third Quarter 2012 Changes		Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Natural gas swaps	$	23	$	27
Natural gas options	1		1
Total changes	$	24	$	28

The net hedge volumes of energy-related derivative contracts were as follows: 

	September 30, 2012	June 30, 2012	December 31, 2011
	mmBtu Volume
	(in millions)
Commodity – Natural gas swaps	62	50	35
Commodity – Natural gas options	1	1	3
Total hedge volume	63	51	38

The weighted average swap contract cost above market prices was approximately $0.20 per mmBtu as of September 30, 2012, $0.72 per mmBtu as of June 30, 2012, and $1.14 per mmBtu as of December 31, 2011. The change in option premiums is primarily attributable to the volatility of the market and the underlying change in the natural gas price. Natural gas settlements are recovered through Gulf Power's fuel cost recovery clause.

Regulatory hedges relate to Gulf Power's fuel-hedging program where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through Gulf Power's fuel cost recovery clause.

Unrealized pre-tax gains and losses recognized in income for the three and nine months ended September 30, 2012 and 2011 for energy-related derivative contracts that are not hedges were not material.

Gulf Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows:

	September 30, 2012     Fair Value Measurements
	Total			Maturity
	Fair Value			Year 1			Years 2&3			Years 4&5
	(in millions)
Level 1	$	—		$	—		$	—		$	—
Level 2	(13		)	(9		)	(5		)	1
Level 3	—			—			—			—
Fair value of contracts outstanding at end of period	$	(13	)	$	(9	)	$	(5	)	$	1

GULF POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Gulf Power. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Gulf Power and its derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Gulf Power does not expect the impact of these rules to be material.

For additional information, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" of Gulf Power in Item 7 and Note 1 under "Financial Instruments" and Note 10 to the financial statements of Gulf Power in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein.

Financing Activities

In January 2012, Gulf Power issued to Southern Company 400,000 shares of Gulf Power's common stock, without par value, and realized proceeds of $40 million. The proceeds were used to repay a portion of Gulf Power's short-term debt and for other general corporate purposes, including Gulf Power's continuous construction program.

In May 2012, Gulf Power issued $100 million aggregate principal amount of Series 2012A 3.10% Senior Notes due May 15, 2022. The proceeds from the sale of the Series 2012A Senior Notes were used by Gulf Power for the redemption in June 2012 of all of approximately $61 million aggregate principal amount of Gulf Power's Series F 5.60% Senior Insured Quarterly Notes due April 1, 2033 and $30 million aggregate principal amount of Gulf Power's Series H 5.25% Senior Notes due July 15, 2033, to repay a portion of its outstanding short-term indebtedness, and for general corporate purposes, including Gulf Power's continuous construction program.

In addition to any financings that may be necessary to meet capital requirements, contractual obligations, and storm-recovery, Gulf Power plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-cost capital if market conditions permit.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Mississippi Power operates as a vertically integrated utility providing electricity to retail customers within its traditional service territory located within the State of Mississippi and to wholesale customers in the Southeast. Many factors affect the opportunities, challenges, and risks of Mississippi Power's business of selling electricity. These factors include the ability to maintain a constructive regulatory environment, to maintain and grow energy sales given economic conditions, and to effectively manage and secure timely recovery of rising costs. These costs include those related to projected long-term demand growth, increasingly stringent environmental standards, reliability, fuel, capital expenditures, and restoration following major storms. In addition, Mississippi Power is currently constructing the Kemper IGCC. Mississippi Power has various regulatory mechanisms that operate to address cost recovery. Appropriately balancing required costs and capital expenditures with customer prices will continue to challenge Mississippi Power for the foreseeable future.

On June 22, 2012, the Mississippi PSC denied the proposed Certificated New Plant-A (CNP-A) rate schedule and the 2012 rate recovery filings submitted by Mississippi Power, pending a final ruling from the Mississippi Supreme Court regarding the motion for stay and notice of appeal filed by the Sierra Club on April 26, 2012 relating to the Mississippi PSC's issuance of the CPCN for the Kemper IGCC. On July 9, 2012, Mississippi Power appealed the Mississippi PSC's June 22, 2012 decision to the Mississippi Supreme Court and requested interim rates under bond of $55.3 million. On July 31, 2012, the Mississippi Supreme Court denied Mississippi Power's request for interim rates under bond while the Mississippi Supreme Court decides Mississippi Power's appeal of the Mississippi PSC's June 22, 2012 decision. On September 13, 2012, the Mississippi PSC filed the record in the appeal of the Mississippi PSC's June 22, 2012 decision with the Mississippi Supreme Court. If the Mississippi Supreme Court does not render a decision within 180 days of the filing of the record, the rates proposed on June 14, 2012 will go into effect, subject to refund by Mississippi Power. The ultimate outcome of this matter cannot be determined at this time.

Mississippi Power continues to focus on several key performance indicators. In recognition that Mississippi Power's long-term financial success is dependent upon how well it satisfies its customers' needs, Mississippi Power's retail base rate mechanism, PEP, includes performance indicators that directly tie customer service indicators to Mississippi Power's allowed return. In addition to the PEP performance indicators, Mississippi Power focuses on other performance measures, including broader measures of customer satisfaction, plant availability, system reliability, and net income after dividends on preferred stock. For additional information on these indicators, see MANAGEMENT'S DISCUSSION AND ANALYSIS – OVERVIEW – "Key Performance Indicators" of Mississippi Power in Item 7 of the Form 10-K.

RESULTS OF OPERATIONS

Net Income

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$16.6	43.7	$37.0	47.5

Mississippi Power's net income after dividends on preferred stock for the third quarter 2012 was $54.6 million compared to $38.0 million for the corresponding period in 2011. The increase in net income after dividends on preferred stock for the third quarter 2012 was the result of an increase in AFUDC equity primarily related to the construction of the Kemper IGCC, a decrease in operations and maintenance expenses, and an increase in territorial base revenues primarily due to a wholesale base rate increase effective April 1, 2012, partially offset by an increase in interest expense, net of amounts capitalized.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Mississippi Power's net income after dividends on preferred stock for year-to-date 2012 was $114.9 million compared to $77.9 million for the corresponding period in 2011. The increase in net income after dividends on preferred stock for year-to-date 2012 was primarily due to an increase in AFUDC equity primarily related to the construction of the Kemper IGCC, a decrease in operations and maintenance expenses, and an increase in territorial base revenues primarily due to a wholesale base rate increase effective April 1, 2012. These factors were partially offset by an increase in depreciation and amortization and an increase in interest expense, net of amounts capitalized.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Integrated Coal Gasification Combined Cycle" and Note (B) to the Condensed Financial Statements herein for additional information regarding the Kemper IGCC.

Retail Revenues

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(13.0)	(5.6)	$(42.1)	(6.8)

In the third quarter 2012, retail revenues were $220.3 million compared to $233.3 million for the corresponding period in 2011. For year-to-date 2012, retail revenues were $578.7 million compared to $620.8 million for the corresponding period in 2011.

Details of the change to retail revenues were as follows:

	Third Quarter 2012					Year-to-Date 2012
	(in millions)			(% change)		(in millions)			(% change)
Retail – prior year	$	233.3				$	620.8

Retail – current year	$	220.3		(5.6	)%	$	578.7		(6.8	)%

Revenues associated with changes in rates and pricing decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 due to decreases of $0.1 million and $1.9 million, respectively, related to the ECO Plan rate.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Environmental Compliance Overview Plan" of Mississippi Power in Item 7 of the Form 10-K and FUTURE EARNINGS POTENTIAL – "PSC Matters – Environmental Compliance Overview Plan" herein for additional information.

Revenues attributable to changes in sales increased in the third quarter 2012 when compared to the corresponding period in 2011. Weather-adjusted KWH energy sales to residential and commercial customers increased 2.2% and 1.8%, respectively, when compared to the corresponding period in 2011 due to a small increase in the number of residential customers and slightly improving economic conditions. KWH energy sales to industrial customers decreased 4.0% due to decreased production for several larger customers.

Revenues attributable to changes in sales increased for year-to-date 2012 when compared to the corresponding period in 2011 primarily due to an increase in sales to residential, commercial, and industrial customers. KWH energy sales to industrial customers increased 1.2% due to increased production for several larger customers.

116

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Weather-adjusted KWH energy sales to residential and commercial customers increased 2.3% and 1.5%, respectively, when compared to the corresponding period in 2011. The increase in residential and commercial sales was primarily due to a small increase in the number of residential customers and slightly improving economic conditions.

Revenues attributable to changes in weather decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily due to milder weather.

Fuel and other cost recovery revenues decreased in the third quarter and year-to-date 2012 when compared to the corresponding periods in 2011 primarily as a result of lower recoverable fuel costs, partially offset by an increase in revenues related to the retail portion of ad valorem taxes. Recoverable fuel costs include fuel and purchased power expenses reduced by the fuel portion of wholesale revenues from energy sold to customers outside Mississippi Power's service territory. Electric rates include provisions to adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these provisions, fuel revenues generally equal fuel expenses, including the energy component of purchased power costs, and do not affect net income. The retail portion of ad valorem tax expense is recoverable under Mississippi Power's ad valorem tax cost recovery clause and, therefore, does not affect net income.

Wholesale Revenues – Non-Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(1.1)	(1.4)	$(20.4)	(9.5)

Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy compared to the cost of Mississippi Power's and the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation. Increases and decreases in revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income.

In the third quarter 2012, wholesale revenues from non-affiliates were $77.0 million compared to $78.1 million for the corresponding period in 2011. The decrease was due to a $7.4 million decrease in energy revenues, of which $2.7 million was associated with a decrease in KWH sales due to lower demand primarily resulting from milder weather in the third quarter 2012 compared to the corresponding period in 2011 and $4.7 million was associated with lower fuel prices, partially offset by a $6.3 million increase in revenues primarily resulting from a wholesale base rate increase effective April 1, 2012.

For year-to-date 2012, wholesale revenues from non-affiliates were $195.4 million compared to $215.8 million for the corresponding period in 2011. The decrease was due to a $28.4 million decrease in energy revenues, of which $9.9 million was associated with a decrease in KWH sales due to lower demand primarily resulting from milder weather in 2012 compared to the corresponding period in 2011 and $18.5 million was associated with lower fuel prices, partially offset by an $8.0 million increase in revenues primarily resulting from a wholesale base rate increase effective April 1, 2012.

Wholesale Revenues – Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(5.6)	(56.8)	$(11.8)	(46.5)

Wholesale revenues from sales to affiliated companies within the Southern Company system will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since the energy is generally sold at marginal cost.

117

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In the third quarter 2012, wholesale revenues from affiliates were $4.2 million compared to $9.8 million for the corresponding period in 2011. The decrease was primarily due to a $1.0 million decrease in capacity revenues and a $4.6 million decrease in energy revenues, of which $2.3 million was associated with lower prices and $2.3 million was associated with a decrease in KWH sales.

For year-to-date 2012, wholesale revenues from affiliates were $13.6 million compared to $25.4 million for the corresponding period in 2011. The decrease was primarily due to a $1.4 million decrease in capacity revenues and a $10.4 million decrease in energy revenues, of which $8.5 million was associated with lower prices and $1.9 million was associated with a decrease in KWH sales.

Fuel and Purchased Power Expenses

	Third Quarter 2012 vs. Third Quarter 2011					Year-to-Date 2012 vs. Year-to-Date 2011

Purchased power – affiliates	7.2			84.4		(1.3		)	(3.6	)
Total fuel and purchased power expenses	$	(24.2	)			$	(82.6	)

In the third quarter 2012, total fuel and purchased power expenses were $144.6 million compared to $168.8 million for the corresponding period in 2011. The decrease was primarily due to a $12.7 million decrease in the cost of fuel and purchased power and an $11.5 million decrease in total KWHs generated and purchased.

For year-to-date 2012, total fuel and purchased power expenses were $361.5 million compared to $444.1 million for the corresponding period in 2011. The decrease was primarily due to a $56.6 million decrease in the cost of fuel and purchased power and a $26.0 million decrease in total KWHs generated and purchased.

Fuel and purchased power energy transactions do not have a significant impact on earnings since energy expenses are generally offset by energy revenues through Mississippi Power's fuel cost recovery clause. See FUTURE EARNINGS POTENTIAL – "PSC Matters" herein for additional information.

Details of Mississippi Power's generation and purchased power were as follows:

	Third Quarter 2012	Third Quarter 2011	Year-to-Date 2012	Year-to-Date 2011
Total generation (millions of KWHs)	3,534	3,990	9,875	10,579

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Fuel

In the third quarter 2012, fuel expense was $127.6 million compared to $158.0 million for the corresponding period in 2011. The decrease was primarily due to a 22.9% decrease in the average cost of natural gas per KWH generated primarily resulting from lower natural gas prices and a 12.9% decrease in generation from Mississippi Power's facilities resulting from lower energy demand in the third quarter 2012.

For year-to-date 2012, fuel expense was $321.7 million compared to $402.7 million for the corresponding period in 2011. The decrease was primarily due to a 26.2% decrease in the average cost of natural gas per KWH generated primarily resulting from lower natural gas prices and a 7.5% decrease in generation from Mississippi Power's facilities resulting from lower energy demand primarily due to milder weather in 2012.

Purchased Power – Non-Affiliates

In the third quarter 2012, purchased power expense from non-affiliates was $1.4 million compared to $2.3 million for the corresponding period in 2011. The decrease was primarily the result of a 62.1% decrease in the average cost of purchased power per KWH, partially offset by a 54.9% increase in the volume of KWHs purchased. The decrease in the average cost per KWH purchased was due to a lower marginal cost of fuel. The increase in the volume of KWHs purchased was due to a lower marginal cost of fuel compared to the cost of generation.

For year-to-date 2012, purchased power expense from non-affiliates was $4.4 million compared to $4.7 million for the corresponding period in 2011. The decrease was primarily the result of a 47.3% decrease in the average cost of purchased power per KWH, partially offset by an 80.5% increase in the volume of KWHs purchased. The decrease in the average cost per KWH purchased was due to a lower marginal cost of fuel. The increase in the volume of KWHs purchased was due to a lower market cost of available energy compared to the cost of generation.

Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the availability of the Southern Company system's generation.

Purchased Power – Affiliates

In the third quarter 2012, purchased power expense from affiliates was $15.7 million compared to $8.5 million for the corresponding period in 2011. The increase was primarily due to a 105.9% increase in the volume of KWHs purchased, partially offset by a 10.6% decrease in the average cost of purchased power per KWH.

For year-to-date 2012, purchased power expense from affiliates was $35.4 million compared to $36.7 million for the corresponding period in 2011. The decrease was primarily due to a 17.9% decrease in the average cost of purchased power per KWH, partially offset by a 17.3% increase in the volume of KWHs purchased.

Energy purchases from affiliates will vary depending on demand for energy and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC, as approved by the FERC.

Other Operations and Maintenance Expenses

In the third quarter 2012, other operations and maintenance expenses were $53.5 million compared to $65.9 million for the corresponding period in 2011. The decrease was primarily due to an $11.1 million decrease in rent expense and expenses under a long-term service agreement resulting from the expiration of an operating lease for Plant Daniel Units 3 and 4 in October 2011 and a $1.4 million decrease in transmission and distribution expenses primarily related to overhead line maintenance and vegetation management costs.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For year-to-date 2012, other operations and maintenance expenses were $168.9 million compared to $200.7 million for the corresponding period in 2011. The decrease was primarily due to a $31.6 million decrease in rent expense and expenses under a long-term service agreement resulting from the expiration of an operating lease for Plant Daniel Units 3 and 4 in October 2011 and a $3.6 million decrease in generation maintenance expenses. The decreases were partially offset by a $3.1 million increase in administrative and general expenses.

See Notes 1 and 7 to the financial statements of Mississippi Power under "Purchase of the Plant Daniel Combined Cycle Generating Units" and "Long-Term Service Agreements," respectively, in Item 8 of the Form 10-K for additional information.

(change in millions)	(% change)	(change in millions)	(% change)
$1.4	7.5	$6.2	10.5

In the third quarter 2012, depreciation and amortization was $21.1 million compared to $19.7 million for the corresponding period in 2011. The increase was primarily due to a $3.3 million increase in depreciation on additional plant in service and a $1.9 million increase in amortization resulting from the plant acquisition adjustment related to the purchase of Plant Daniel Units 3 and 4. These increases were partially offset by a $2.0 million decrease in amortization primarily resulting from a regulatory deferral associated with the purchase of Plant Daniel Units 3 and 4 and a $1.5 million decrease in ECO Plan amortization.

For year-to-date 2012, depreciation and amortization was $66.1 million compared to $59.9 million for the corresponding period in 2011. The increase was primarily due to a $10.0 million increase in depreciation on additional plant in service and a $5.8 million increase in amortization resulting from the plant acquisition adjustment related to the purchase of Plant Daniel Units 3 and 4. These increases were partially offset by a $6.4 million decrease in amortization primarily resulting from a regulatory deferral associated with the purchase of Plant Daniel Units 3 and 4, a $1.8 million decrease in amortization resulting from a regulatory deferral associated with operations and maintenance expenses that ended in 2011, and a $1.5 million decrease in ECO Plan amortization.

See Note 1 to the financial statements of Mississippi Power under "Purchase of the Plant Daniel Combined Cycle Generating Units" and "Depreciation and Amortization" in Item 8 of the Form 10-K for additional information.

(change in millions)	(% change)	(change in millions)	(% change)
$1.7	9.2	$7.3	13.7

In the third quarter 2012, taxes other than income taxes were $20.0 million compared to $18.3 million for the corresponding period in 2011. The increase was primarily due to a $2.5 million increase in ad valorem taxes resulting from the expiration of a tax exemption related to Plant Daniel Units 3 and 4, partially offset by a $0.4 million decrease in franchise taxes and a $0.4 million decrease in payroll taxes.

For year-to-date 2012, taxes other than income taxes were $60.3 million compared to $53.0 million for the corresponding period in 2011. The increase was primarily due to a $9.2 million increase in ad valorem taxes resulting from the expiration of a tax exemption related to Plant Daniel Units 3 and 4, partially offset by a $1.8 million decrease in franchise taxes.

The retail portion of ad valorem taxes is recoverable under Mississippi Power's ad valorem tax cost recovery clause and, therefore, does not affect net income.

In the third quarter 2012, interest expense, net of amounts capitalized was $9.7 million compared to $3.9 million for the corresponding period in 2011. Capitalized interest primarily resulting from AFUDC debt associated with the Kemper IGCC in the third quarter 2012 was $9.7 million compared to $2.6 million for the corresponding period in 2011. The increase in interest expense, net of amounts capitalized was primarily due to a $12.2 million increase in interest expense associated with the issuances of new long-term debt in October 2011, March 2012, and August 2012 and a $3.8 million increase in interest expense resulting from the receipt of a $150.0 million interest-bearing refundable deposit from SMEPA in March 2012 related to its pending purchase of an undivided interest in the Kemper IGCC. The increase was partially offset by a $7.1 million increase in capitalized interest primarily resulting from AFUDC debt associated with the Kemper IGCC and a $1.9 million decrease in interest expense resulting from the amortization of the fair value adjustment on the assumed debt related to the purchase of Plant Daniel Units 3 and 4 in October 2011.

For year-to-date 2012, interest expense, net of amounts capitalized was $30.6 million compared to $15.4 million for the corresponding period in 2011. Capitalized interest primarily resulting from AFUDC debt associated with the Kemper IGCC for year-to-date 2012 was $22.1 million compared to $5.1 million for the corresponding period in 2011. The increase in interest expense, net of amounts capitalized was primarily due to a $32.0 million increase in interest expense associated with the issuances of new long-term debt in October 2011, March 2012, and August 2012 and an $8.6 million increase in interest expense resulting from the receipt of a $150.0 million interest-bearing refundable deposit from SMEPA in March 2012 related to its pending purchase of an undivided interest in the Kemper IGCC. The increase was partially offset by a $17.0 million increase in capitalized interest primarily resulting from AFUDC debt associated with the Kemper IGCC, a $5.7 million decrease in interest expense

See Note 1 to the financial statements of Mississippi Power under "Purchase of the Plant Daniel Combined Cycle Generating Units" in Item 8 of the Form 10-K and FUTURE EARNINGS POTENTIAL – "Integrated Coal Gasification Combined Cycle" herein for additional information.

Income Taxes

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$3.1	16.8	$4.0	10.5

In the third quarter 2012, income taxes were $21.7 million compared to $18.6 million for the corresponding period in 2011. The increase was primarily due to a $7.9 million increase resulting from higher pre-tax earnings, partially offset by a $4.0 million decrease resulting from higher AFUDC equity, which is non-taxable, a $0.3 million decrease in unrecognized tax benefits, and a $0.5 million decrease due to the actualization of the 2011 tax return in the third quarter 2012.

For year-to-date 2012, income taxes were $42.3 million compared to $38.3 million for the corresponding period in 2011. The increase was primarily due to a $15.8 million increase resulting from higher pre-tax earnings and a $1.0 million increase due to lower State of Mississippi manufacturing investment tax credits, partially offset by a $10.7 million decrease resulting from higher AFUDC equity, which is non-taxable, a $1.5 million decrease in unrecognized tax benefits, and a $0.5 million decrease due to the actualization of the 2011 tax return in the third quarter 2012.

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Mississippi Power's future earnings potential. The level of Mississippi Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Mississippi Power's business of selling electricity. These factors include Mississippi Power's ability to maintain a constructive regulatory environment that continues to allow for the timely recovery of prudently incurred costs during a time of increasing costs. Future earnings in the near term will depend, in part, upon maintaining energy sales which is subject to a number of factors. These factors include weather, competition, new energy contracts with neighboring utilities, energy conservation practiced by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or decline in Mississippi Power's service territory. Changes in economic conditions impact sales for Mississippi Power and the pace of the economic recovery remains uncertain. The timing and extent of the economic recovery will impact growth and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Mississippi Power in Item 7 of the Form 10-K.

Environmental Matters

Compliance costs related to federal and state environmental statutes and regulations could affect earnings if such costs cannot continue to be fully recovered in rates on a timely basis. Environmental compliance spending over the next several years may differ materially from the amounts estimated. The timing, specific requirements, and estimated costs could change as environmental statutes and regulations are adopted or modified. Further, higher costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could negatively affect results of operations, cash flows, and financial condition. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" of Mississippi Power in Item 7 and Note 3 to the financial statements of Mississippi Power under "Environmental Matters" in Item 8 of the Form 10-K for additional information.

On October 8, 2012, the plaintiffs filed for review of the decision by the U.S. Court of Appeals for the Ninth Circuit. The ultimate outcome of this matter cannot be determined at this time.

Environmental Statutes and Regulations

General

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – General" of Mississippi Power in Item 7 of the Form 10-K for information regarding Mississippi Power's estimated base level capital expenditures to comply with existing statutes and regulations for 2012 through 2014, as well as Mississippi Power's preliminary estimates for potential incremental environmental compliance investments associated with complying with the EPA's final Mercury and Air Toxics Standards (MATS) rule (formerly referred to as the Utility Maximum Achievable Control Technology rule) and the EPA's proposed water and coal combustion byproducts rules.

Mississippi Power is continuing to develop its compliance strategy and to assess the potential costs of complying with the MATS rule and the EPA's proposed water and coal combustion byproducts rules. While the final MATS compliance plan is still being developed and the ultimate costs remain uncertain, compliance decisions made in 2012 have allowed Mississippi Power to further develop its cost estimates for compliance with the MATS rule. As a result, estimated compliance costs for the MATS rule in the 2012 through 2014 period have been revised from up to $430 million to approximately $55 million as follows: 

	2012		2013		2014
			(in millions)
MATS rule	$	—	$	5	$	50

123

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In addition, Mississippi Power has further developed its estimated capital expenditures and associated timing of these expenditures to comply with the proposed water and coal combustion byproducts rules, resulting in a reduction, due primarily to timing, in estimated compliance costs for 2012 through 2014. Potential incremental environmental compliance investments to comply with the proposed water and coal combustion byproducts rules have been revised from up to $121 million to approximately $40 million over the 2012 through 2014 period, based on the assumption that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule. These potential incremental environmental compliance investments are estimated as follows: 

	2012		2013		2014
			(in millions)
Proposed water and coal combustion byproducts rules	$	1	$	10	$	30

While Mississippi Power's ultimate costs of compliance with the MATS rule and the proposed water and coal combustion byproducts rules remain uncertain, Mississippi Power estimates that compliance costs through 2021 (assuming that coal combustion byproducts will continue to be regulated as non-hazardous solid waste under the proposed rule) will be at the low end of the $1 billion to $2 billion range provided in the Form 10-K. Included in this amount is approximately $354 million that is also included in the 2012 through 2014 base level capital investment of Mississippi Power described herein in anticipation of these rules. See FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" herein for additional information.

Mississippi Power's ultimate compliance strategy and actual future environmental capital expenditures are dependent on development of the final MATS compliance plan and will be affected by the final requirements of new or revised environmental regulations that are promulgated; the outcome of any legal challenges to the environmental rules; the cost, availability, and existing inventory of emissions allowances; and Mississippi Power's fuel mix. Compliance costs may arise from retirement and replacement of existing units, installation of additional environmental controls, upgrades to the transmission system, and changing fuel sources for certain existing units. The ultimate outcome of these matters cannot be determined at this time.

Air Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Air Quality" of Mississippi Power in Item 7 of the Form 10-K for additional information on the eight-hour ozone and fine particulate matter air quality standards, the MATS rule, the Cross-State Air Pollution Rule (CSAPR), and the Clean Air Visibility Rule (CAVR).

On May 21, 2012, the EPA published its final determination of nonattainment areas based on the 2008 eight-hour ozone air quality standards. None of the areas within Mississippi Power's service territory were designated as nonattainment areas.

On June 14, 2012, the EPA proposed a rule that would increase the stringency of the fine particulate matter national ambient air quality standards. If adopted, the proposed standards could result in the designation of new nonattainment areas within Mississippi Power's service territory. As part of a related settlement, the EPA has agreed to finalize the proposed rule by December 14, 2012. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Numerous petitions for administrative reconsideration of the MATS rule, including a petition by Southern Company and its subsidiaries, including Mississippi Power, have been filed with the EPA. Challenges to the final rule have also been filed in the U.S. District Court for the District of Columbia by numerous states, environmental organizations, industry groups, and others. The impact of the MATS rule will depend on the outcome of these and any other legal challenges and, therefore, cannot be determined at this time.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

On August 21, 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated CSAPR in its entirety and directed the EPA to continue to administer the Clean Air Interstate Rule pending the EPA's development of a valid replacement. The vacatur of CSAPR creates additional uncertainty with respect to whether additional controls may be required for CAVR and best available retrofit technology compliance. On October 5, 2012, the EPA filed for review of the decision by the U.S. Court of Appeals for the District of Columbia Circuit. The ultimate outcome of this matter depends on the outcome of any legal challenges and further action by the EPA and cannot be determined at this time.

On August 29, 2012, the EPA published proposed revisions to the New Source Performance Standard (NSPS) for Stationary Combustion Turbines (CTs). If finalized, the revisions would apply the NSPS to all new, reconstructed, and modified CTs, including CTs at combined cycle units, during all periods of operation, including startup and shutdown, and alter the criteria for determining when an existing CT has been reconstructed. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Water Quality

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Water Quality" of Mississippi Power in Item 7 of the Form 10-K for additional information on the proposed rules regarding certain cooling water intake structures. The EPA has entered into an amended settlement agreement to extend the deadline for issuing a final rule until June 27, 2013. The ultimate outcome of this rulemaking will depend on the final rule and the outcome of any legal challenges and cannot be determined at this time.

Coal Combustion Byproducts

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Statutes and Regulations – Coal Combustion Byproducts" of Mississippi Power in Item 7 of the Form 10-K for additional information. Environmental groups and other parties have filed lawsuits in the U.S. District Court for the District of Columbia seeking to require the EPA to complete its rulemaking process and issue final regulations pertaining to the regulation of coal combustion byproducts. The ultimate outcome of these matters cannot be determined at this time.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Mississippi Power in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

On January 20, 2012, Mississippi Power reached a settlement agreement with its wholesale customers, which was executed by all parties on March 9, 2012. The settlement agreement provides that base rates under the cost-based electric tariff will increase by approximately $22.6 million over a 12-month period with revised rates effective April 1, 2012. In 2012, the amount of base rate revenues to be received from the agreed upon increase will be approximately $17.0 million. On March 12, 2012, Mississippi Power filed an unopposed motion to place wholesale Municipal and Rural Associations (MRA) interim rates into effect pending approval of the settlement agreement between the parties by the FERC. On March 28, 2012, the FERC approved the motion to place interim rates into effect beginning in May 2012. On September 27, 2012, Mississippi Power, with its wholesale customers, filed a final settlement agreement with the FERC. On November 5, 2012, the settlement judge certified the settlement agreement to the FERC with the recommendation that it be approved. A decision by the FERC is expected by the end of 2012. The ultimate outcome of this matter cannot be determined at this time.

PSC Matters

General

On August 7, 2012, the Mississippi PSC issued an order for the purpose of investigating and reviewing for informational purposes only the ROE formulas used by Mississippi Power and all other regulated electric utilities in Mississippi. The ultimate outcome of this matter cannot be determined at this time.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

On February 14, 2012, Mississippi Power submitted its 2012 ECO Plan filing, which proposed a 0.3% increase in annual revenues for Mississippi Power. In compliance with the CPCN to construct a flue gas desulfurization system (scrubber) on Plant Daniel Units 1 and 2, Mississippi Power revised the 2012 ECO Plan filing to exclude scrubber expenditures from rate base, which resulted in a 0.16% decrease in annual revenues. On June 22, 2012, the 2012 ECO Plan filing, including the proposed rate decrease, was approved by the Mississippi PSC, effective on June 29, 2012.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a scrubber on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court of Harrison County, Mississippi (Chancery Court). These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, with Mississippi Power's portion being $330 million, excluding AFUDC. The project is scheduled for completion in December 2015. Mississippi Power's portion of the cost is expected to be recovered through the ECO Plan. As of September 30, 2012, total project expenditures were $118.4 million, with Mississippi Power's portion being $59.2 million. The ultimate outcome of this matter cannot be determined at this time.

Certificated New Plant

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Certificated New Plant" of Mississippi Power in Item 7 and Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "Integrated Coal Gasification Combined Cycle" herein for additional information.

On May 23, 2012, the Mississippi Public Utilities Staff signed a joint stipulation with Mississippi Power to establish a new rate schedule for CNP-A, a proposed cost recovery mechanism designed specifically to recover financing costs during the construction phase of the Kemper IGCC. An amended and restated stipulation was subsequently executed and filed on June 1, 2012. On June 14, 2012, Mississippi Power submitted to the Mississippi PSC a proposed supplemental compliance filing to establish the new CNP-A rate schedule and a stipulated rate increase based upon the revenue request of between $55.3 million and $58.6 million to recover financing costs over the remainder of 2012.

On June 22, 2012, the Mississippi PSC denied the proposed CNP-A rate schedule and the 2012 rate recovery filings submitted by Mississippi Power, pending a final ruling from the Mississippi Supreme Court regarding the motion for stay and notice of appeal filed by the Sierra Club on April 26, 2012 relating to the Mississippi PSC's issuance of the CPCN for the Kemper IGCC. On July 9, 2012, Mississippi Power appealed the Mississippi PSC's June 22, 2012 decision to the Mississippi Supreme Court and requested interim rates under bond of $55.3 million. On July 31, 2012, the Mississippi Supreme Court denied Mississippi Power's request for interim rates under bond while the Mississippi Supreme Court decides Mississippi Power's appeal of the Mississippi PSC's June 22, 2012 decision.

On September 13, 2012, the Mississippi PSC filed the record in the appeal of the Mississippi PSC's June 22, 2012 decision with the Mississippi Supreme Court. If the Mississippi Supreme Court does not render a decision within 180 days of the filing of the record, the rates proposed on June 14, 2012 will go into effect, subject to refund by Mississippi Power.

The ultimate outcome of this matter cannot be determined at this time.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Fuel Cost Recovery" of Mississippi Power in Item 7 and Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Fuel Cost Recovery" in Item 8 of the Form 10-K for information regarding Mississippi Power's fuel cost recovery.

127

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

At September 30, 2012, the amount of over recovered retail fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $52.8 million compared to $42.4 million at December 31, 2011. Mississippi Power also has wholesale MRA and Market Based (MB) fuel cost recovery factors. At September 30, 2012, the amount of over recovered wholesale MRA and MB fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $16.8 million and $2.1 million, respectively, compared to $14.3 million and $2.2 million, respectively, at December 31, 2011. In addition, at September 30, 2012, the amount of under recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $0.2 million. At December 31, 2011, the amount of over recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $1.7 million. Mississippi Power's operating revenues are adjusted for differences in actual recoverable fuel cost and amounts billed in accordance with the currently approved cost recovery rate. Accordingly, any changes in the billing factors will not have a significant effect on Mississippi Power's revenues or net income, but will affect annual cash flow.

Storm Damage Cost Recovery

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Storm Damage Cost Recovery" in Item 8 in the Form 10-K for information regarding Mississippi Power's storm damage cost recovery. In August 2012, Hurricane Isaac hit the Gulf Coast of the United States and caused damage within Mississippi Power's service area. The estimated total storm restoration costs relating to Hurricane Isaac through September 30, 2012 were $9.7 million. Mississippi Power maintains a reserve to cover the cost of damage from major storms to its transmission and distribution facilities and generally the cost of uninsured damage to its generation facilities and other property. At September 30, 2012, the balance in the storm reserve was $58.7 million.

Integrated Coal Gasification Combined Cycle

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Integrated Coal Gasification Combined Cycle" of Mississippi Power in Item 7 and Note 3 to the financial statements of Mississippi Power under "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K for information regarding Mississippi Power's construction of the Kemper IGCC.

In May 2010, Mississippi Power filed a motion with the Mississippi PSC accepting the conditions contained in the Mississippi PSC order confirming Mississippi Power's application for a CPCN authorizing the acquisition, construction, and operation of the Kemper IGCC. In June 2010, the Mississippi PSC issued the CPCN (2010 MPSC Order).

In June 2010, the Sierra Club filed an appeal of the Mississippi PSC's June 2010 decision to grant the CPCN for the Kemper IGCC with the Chancery Court. Subsequently, in July 2010, the Sierra Club also filed an appeal directly with the Mississippi Supreme Court. In October 2010, the Mississippi Supreme Court dismissed the Sierra Club's direct appeal. In February 2011, the Chancery Court issued a judgment affirming the 2010 MPSC Order and, in March 2011, the Sierra Club appealed the Chancery Court's decision to the Mississippi Supreme Court. On March 15, 2012, the Mississippi Supreme Court reversed the Chancery Court's decision and the 2010 MPSC Order and remanded the matter to the Mississippi PSC to correct the 2010 MPSC Order. The Mississippi Supreme Court concluded that the 2010 MPSC Order did not cite in sufficient detail substantial evidence upon which the Mississippi Supreme Court could determine the basis for the findings of the Mississippi PSC granting the CPCN.

On March 30, 2012, the Mississippi PSC issued temporary authorization for the continuation of construction of the Kemper IGCC. On April 24, 2012, the Mississippi PSC issued a detailed order on remand (2012 MPSC Order) confirming the CPCN for the Kemper IGCC subject to the same conditions set forth in the 2010 MPSC Order. On April 26, 2012, the Sierra Club filed a motion for stay and a notice of appeal of the 2012 MPSC Order with the Chancery Court. On May 18, 2012, Mississippi Power's motion to join the appeal was approved. On August 7, 2012, the Sierra Club withdrew its motion for stay.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The certificated cost estimate of the Kemper IGCC is $2.4 billion, net of $245.3 million of grants awarded to the project by the DOE under the Clean Coal Power Initiative Round 2 (CCPI2) and excluding the cost of the lignite mine and equipment and the carbon dioxide (CO₂) pipeline facilities. The 2012 MPSC Order, like the 2010 MPSC Order, (1) approved a construction cost cap of up to $2.88 billion (exemptions from the cost cap include the cost of the lignite mine and equipment, the CO₂ pipeline facilities, AFUDC, and certain general exceptions, including change of law, force majeure, and beneficial capital, which exists when Mississippi Power demonstrates that the purpose and effect of the construction cost increase is to produce efficiencies that will result in a neutral or favorable effect on the ratepayers, relative to the original proposal), (2) provided for the establishment of operational cost and revenue parameters based upon assumptions in Mississippi Power's proposal, and (3) approved financing cost recovery on CWIP balances not to exceed the certificated cost estimate, which provided for the accrual of AFUDC in 2010 and 2011 and provides for the current recovery of financing costs on 100% of CWIP in 2012, 2013, and through May 1, 2014 (provided that the amount of CWIP allowed is (i) reduced by the amount of state and federal government construction cost incentives received by Mississippi Power in excess of $296 million to the extent that such amount increases cash flow for the pertinent regulatory period and (ii) justified by a showing that such CWIP allowance will benefit customers over the life of the Kemper IGCC).

Mississippi Power's current cost estimate for the Kemper IGCC equals the $2.88 billion cost cap, including a $40 million to $50 million contingency. The Mississippi PSC and the Mississippi Public Utilities Staff have engaged their independent monitors to assess the current cost estimates and schedule projections for the Kemper IGCC. These consultants are issuing reports with their own opinions as to the likelihood that costs for the Kemper IGCC will remain under the $2.88 billion cost cap and as to the expected in-service date. While Mississippi Power continues to believe its cost estimate and schedule projection remain appropriate based on the current status of the project, it is possible that Mississippi Power will experience further cost increases and/or schedule delays with respect to the Kemper IGCC. Certain factors have caused and may continue to cause the costs for the Kemper IGCC to increase and/or schedule delays to occur including, but not limited to, costs and productivity of labor, adverse weather conditions, shortages and inconsistent quality of equipment, materials and labor, contractor or supplier delay or non-performance under construction or other agreements, and unforeseen engineering problems. To the extent that costs beyond any permitted exceptions to the cost cap exceed $2.88 billion or the Mississippi PSC disallows a portion of the costs relating to the Kemper IGCC, including financing costs, charges to expense may occur and these charges could be material.

The Kemper IGCC, expected to be in service in May 2014, will use locally mined lignite (an abundant, lower heating value coal) from a mine adjacent to the Kemper IGCC as fuel. The mine is scheduled to be placed into service in June 2013. In conjunction with the Kemper IGCC, Mississippi Power will own the lignite mine and equipment and has acquired and will continue to acquire mineral reserves located around the Kemper IGCC site in Kemper County. The estimated capital cost of the mine is approximately $245 million, of which $127 million has been incurred through September 30, 2012.

In May 2010, Mississippi Power executed a 40-year management fee contract with Liberty Fuels Company, LLC, a wholly-owned subsidiary of The North American Coal Corporation (Liberty Fuels), which will develop, construct, and manage the mining operations. Because Liberty Fuels conducts all of its activities on behalf of Mississippi Power, Liberty Fuels qualifies as a variable interest entity for which Mississippi Power is the primary beneficiary. The contract with Liberty Fuels is effective through the end of the mine reclamation. As the mining permit holder, Liberty Fuels has a legal obligation to perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities. Consistent with the requirements of consolidation accounting, Liberty Fuels is consolidated in the financial statements of Mississippi Power and accordingly the asset retirement cost and the ARO have been recorded in Mississippi Power's financial statements. In addition to the obligation to fund the reclamation activities, Mississippi Power currently provides working capital support to Liberty Fuels through cash advances for capital purchases, payroll, and other operating expenses.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In December 2011, the Mississippi Department of Environmental Quality (MDEQ) approved the surface coal mining and the water pollution control permits for the mining operations operated by Liberty Fuels. On January 12, 2012, two individuals each filed a notice of appeal and a request for evidentiary hearing with the MDEQ regarding the surface coal mining and water pollution control permits. On March 8, 2012, the MDEQ permit board affirmed its issuance of the surface coal mining and water pollution control permits.

In 2009, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $133 million of Internal Revenue Code Section 48A tax credits (Phase I) to Mississippi Power. In April 2011, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $279 million of Internal Revenue Code Section 48A tax credits (Phase II) to Mississippi Power. The utilization of Phase I and Phase II credits is dependent upon meeting the IRS certification requirements, including an in-service date no later than May 11, 2014 for the Phase I credits and April 19, 2016 for the Phase II credits. In order to remain eligible for the Phase II credits, Mississippi Power plans to capture and sequester (via enhanced oil recovery) at least 65% of the CO₂ produced by the Kemper IGCC during operations in accordance with the rules for Section 48A investment tax credits. Through September 30, 2012, Mississippi Power received or accrued tax benefits totaling $276.8 million for these tax credits, which will be amortized as a reduction to depreciation and amortization over the life of the Kemper IGCC. On October 15, 2012, Mississippi Power filed an application with the DOE for certification of the Kemper IGCC for additional tax credits under the Internal Revenue Code Section 48A (Phase III). A portion of the tax credits realized by Mississippi Power may be subject to recapture upon successful completion of SMEPA's purchase of an undivided interest in the Kemper IGCC. Based on current tax laws and regulations in effect, Mississippi Power expects to receive substantially all of the tax credits accrued through September 30, 2012 by September 30, 2013.

In July 2010, Mississippi Power and SMEPA entered into an asset purchase agreement whereby SMEPA agreed to purchase a 17.5% undivided interest in the Kemper IGCC. In December 2010, Mississippi Power and SMEPA filed a joint petition with the Mississippi PSC requesting regulatory approval of SMEPA's 17.5% undivided interest in the Kemper IGCC. On February 28, 2012, the Mississippi PSC approved the joint petition for the sale and transfer of 17.5% of the Kemper IGCC to SMEPA. On June 29, 2012, Mississippi Power and SMEPA signed an amendment to the asset purchase agreement whereby SMEPA extended its option to purchase until December 31, 2012 and reduced its purchase commitment percentage from a 17.5% to a 15% undivided interest in the Kemper IGCC, subject to approval by the Mississippi PSC. The closing of this transaction is conditioned upon execution of a joint ownership and operating agreement, receipt of all construction permits, appropriate regulatory approvals, financing, and other conditions. On September 27, 2012, SMEPA received a conditional loan commitment from Rural Utilities Service to provide funding for SMEPA's undivided interest in the Kemper IGCC.

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the purchase. While the expectation is that the amount will be applied to the purchase price at closing, Mississippi Power would be required to refund the deposit upon the termination of the asset purchase agreement, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies. Given the interest-bearing nature of the deposit and SMEPA's ability to request a refund, the deposit has been presented as a current liability in Mississippi Power's Condensed Balance Sheet herein and as financing proceeds in Mississippi Power's Condensed Statement of Cash Flows herein.

As of September 30, 2012, Mississippi Power had spent a total of $2.1 billion on the Kemper IGCC including the cost of the lignite mine and equipment, the CO₂ pipeline facilities, and regulatory filing costs. Of this total, $2.0 billion was included in CWIP (which is net of $245.3 million of CCPI2 grant funds), $30.2 million was recorded in other regulatory assets, $3.0 million was recorded in other deferred charges and assets, and $1.0 million was previously expensed.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Mississippi PSC order established periodic prudence reviews during the annual CWIP review process. Of the total costs of $51 million incurred through March 2009, $46 million has been reviewed and deemed prudent by the Mississippi PSC in the 2010 MPSC Order and again in the 2012 MPSC Order. A decision regarding the remaining $5 million has not been issued. The timing of the review of the remaining Kemper IGCC costs has not been determined.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "PSC Matters – Certificated New Plant" of Mississippi Power in Item 7 and Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "PSC Matters – Certificated New Plant" herein for information on the proposed rate schedules related to the Kemper IGCC.

The ultimate outcome of these matters cannot be determined at this time.

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013). Due to the significant amount of estimated bonus depreciation for 2012, the utilization of a portion of Mississippi Power's tax credits has been delayed. Mississippi Power expects to receive substantially all of the tax credits accrued through September 30, 2012 by September 30, 2013.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Integrated Coal Gasification Combined Cycle" herein for additional information.

Other Matters

Mississippi Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Mississippi Power is subject to certain claims and legal actions arising in the ordinary course of business. Mississippi Power's business activities are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Mississippi Power cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Mississippi Power in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Mississippi Power's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Mississippi Power prepares its financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Mississippi Power in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Mississippi Power's results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Mississippi Power in Item 7 of the Form 10-K for a complete discussion of Mississippi Power's critical accounting policies and estimates related to Electric Utility Regulation, Contingent Obligations, Unbilled Revenues, and Pension and Other Postretirement Benefits.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" of Mississippi Power in Item 7 of the Form 10-K for additional information. Mississippi Power's financial condition remained stable at September 30, 2012. Mississippi Power intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities," and "Capital Requirements and Contractual Obligations" herein for additional information.

Net cash provided from operating activities totaled $157.9 million for the first nine months of 2012, a decrease of $28.8 million as compared to the corresponding period in 2011. The decrease in cash provided from operating activities is primarily due to a decrease in deferred income taxes, a decrease in hedge settlements, an increase in fossil fuel stock, and a decrease in cash related to accounts payable and receivables. The decrease was partially offset by an increase in regulatory clause revenues primarily due to lower fuel costs, an increase in prepaid income taxes, and an increase in other current liabilities primarily due to accrued interest. Net cash used for investing activities totaled $1.1 billion for the first nine months of 2012 primarily due to gross property additions related to the Kemper IGCC. Net cash provided from financing activities totaled $925.5 million for the first nine months of 2012 primarily due to the issuances of senior notes and capital contributions from Southern Company. Fluctuations in cash flow from financing activities vary year to year based on capital needs and the maturity or redemption of securities. 

Significant balance sheet changes for the first nine months of 2012 include an increase in prepaid income taxes of $216.3 million and an increase in accumulated deferred investment tax credits of $176.3 million primarily due to the Kemper IGCC investment tax credit. Total property, plant, and equipment increased $1.2 billion primarily due to the increase in CWIP related to the Kemper IGCC. Interest-bearing refundable deposit related to an asset sale increased $150.0 million due to the receipt of the $150.0 million interest-bearing refundable deposit from SMEPA. Long-term debt increased $512.9 million primarily due to the issuance of $600.0 million of senior notes, partially offset by the redemption of $90.0 million of senior notes. Paid-in capital increased $432.5 million primarily due to $425.0 million of capital contributions from Southern Company.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Mississippi Power in Item 7 of the Form 10-K for a description of Mississippi Power's capital requirements for its construction program, including estimated capital expenditures to comply with existing environmental regulations, scheduled maturities of long-term debt, as well as related interest, leases, purchase commitments, derivative obligations, preferred stock dividends, trust funding requirements, and unrecognized tax benefits. Approximately $151 million will be required through September 30, 2013 to fund maturities of long-term debt.

See FUTURE EARNINGS POTENTIAL – "Environmental Statutes and Regulations – General" herein for a description of Mississippi Power's estimated capital expenditures to comply with the MATS rule and proposed water and coal combustion byproducts rules.

See Note 7 to the financial statements of Mississippi Power in Item 8 of the Form 10-K for information on Mississippi Power's construction program. The construction program of Mississippi Power is currently estimated to include a base level investment of $1.8 billion, $713 million, and $423 million for 2012, 2013, and 2014, respectively. Included in these estimated amounts are expenditures related to the Kemper IGCC of $1.6 billion, $473 million, and $145 million in 2012, 2013, and 2014, respectively, which include additional AFUDC due to the delay in the rate recovery and are net of SMEPA's 15% expected ownership share of the Kemper IGCC of approximately $470 million and $14 million in 2013 and 2014, respectively. See FUTURE EARNINGS POTENTIAL  – "PSC Matters – Certificated New Plant" and "Integrated Coal Gasification Combined Cycle" herein for additional information.

The construction program is subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; storm impacts; changes in environmental statutes and regulations; the outcome of any legal challenges to environmental rules; changes in generating plants, including unit retirements and replacements and adding or changing fuel sources at existing units, to meet new regulatory requirements; changes in FERC rules and regulations; Mississippi PSC approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered.

Sources of Capital

Except as described below with respect to potential DOE loan guarantees, Mississippi Power plans to obtain the funds required for construction and other purposes from sources similar to those used in the past, which were primarily funds from operating cash flows, security issuances, term loans, short-term debt, and equity contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend upon regulatory approval, prevailing market conditions, and other factors. During the first nine months of 2012, Mississippi Power received $425 million in capital contributions from Southern Company. On October 29, 2012, Mississippi Power received $150 million in additional capital contributions from Southern Company. On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA towards its pending purchase of an undivided interest in the Kemper IGCC. Until the acquisition is closed, the deposit bears interest at Mississippi Power's AFUDC rate adjusted for income taxes, which was 9.967% per annum at September 30, 2012. While the expectation is that the amount will be applied to the purchase price at closing, Mississippi Power would be required to refund the deposit upon the termination of the asset purchase agreement, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Mississippi Power in Item 7 of the Form 10-K for additional information.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Mississippi Power has applied to the DOE for federal loan guarantees to finance a portion of the eligible construction costs of the Kemper IGCC. Mississippi Power is in advanced due diligence with the DOE. There can be no assurance that the DOE will issue federal loan guarantees to Mississippi Power. In the event that the DOE does not issue a conditional commitment or a final definitive loan guarantee, Mississippi Power expects to finance the construction of the Kemper IGCC through traditional capital markets financings. Mississippi Power has received $245.3 million in DOE CCPI2 grant funds that were used for the construction of the Kemper IGCC. An additional $25 million in CCPI2 grant funds is expected to be received for the initial operation of the Kemper IGCC.

Mississippi Power's current liabilities sometimes exceed current assets because of the continued use of short-term debt as a funding source to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate significantly due to the seasonality of the business.

At September 30, 2012, Mississippi Power had approximately $216.7 million of cash and cash equivalents. Committed credit arrangements with banks at September 30, 2012, including expiration dates, were as follows: 

Expires										Executable Term Loans				Due Within One Year(a)
2012		2013		2014		Total		Unused		One     Year		Two     Years		Term     Out		No Term Out
(in millions)						(in millions)				(in millions)				(in millions)
$	16	$	120	$	165	$	301	$	301	$	25	$	41	$	66	$	70

(a) Reflects facilities expiring on or before September 30, 2013.

See Note 6 to the financial statements of Mississippi Power under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Most of these arrangements contain covenants that limit debt levels and typically contain cross default provisions that are restricted only to the indebtedness of Mississippi Power. Mississippi Power is currently in compliance with all such covenants. Mississippi Power expects to renew its credit arrangements, as needed, prior to expiration. These credit arrangements provide liquidity support to Mississippi Power's commercial paper borrowings and variable rate pollution control revenue bonds. The amount of variable rate pollution control revenue bonds outstanding requiring liquidity support as of September 30, 2012 was approximately $40 million.

Mississippi Power may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell commercial paper at the request and for the benefit of Mississippi Power and the other traditional operating companies. Proceeds from such issuances for the benefit of Mississippi Power are loaned directly to Mississippi Power. The obligations of each traditional operating company under these arrangements are several and there is no cross affiliate credit support.

During the three months ended September 30, 2012, Mississippi Power had no commercial paper or other short-term debt outstanding.

Management believes that the need for working capital can be adequately met by utilizing commercial paper, lines of credit, and cash.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Credit Rating Risk

Mississippi Power does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to below BBB- and/or Baa3. These contracts are for physical electricity sales, fuel purchases, fuel transportation and storage, emissions allowances, and energy price risk management. At September 30, 2012, the maximum potential collateral requirements under these contracts at a rating below BBB- and/or Baa3 were approximately $290 million. Included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash.

Mississippi Power also has entered into an asset purchase agreement with SMEPA for the pending purchase of an undivided interest in the Kemper IGCC that could require a refund of the $150 million deposit within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies. Additionally, any credit rating downgrade could impact Mississippi Power's ability to access capital markets, particularly the short-term debt market.

On July 3, 2012, Fitch downgraded the issuer default and unsecured long-term debt ratings of Mississippi Power to A- from A and to A from A+, respectively. Fitch also announced that it had downgraded the pollution control revenue bond ratings of Mississippi Power to A from A+ and the preferred stock ratings of Mississippi Power to BBB+ from A-. Fitch revised the ratings outlook for Mississippi Power to negative from stable.

On August 6, 2012, Moody's downgraded the senior unsecured debt and preferred stock ratings of Mississippi Power to A3 from A2 and to Baa2 from Baa1, respectively. Moody's revised the ratings outlook for Mississippi Power to negative from stable.

Market Price Risk

Mississippi Power's market risk exposure relative to interest rate changes for the third quarter 2012 has not changed materially compared with the December 31, 2011 reporting period. Since a significant portion of outstanding indebtedness is at fixed rates, Mississippi Power is not aware of any facts or circumstances that would significantly affect exposures on existing indebtedness in the near term. However, the impact on future financing costs cannot now be determined.

Due to cost-based rate regulation and other various cost recovery mechanisms, Mississippi Power continues to have limited exposure to market volatility in interest rates, foreign currency, commodity fuel prices, and prices of electricity. To mitigate residual risks relative to movements in electricity prices, Mississippi Power enters into physical fixed-price contracts for the purchase and sale of electricity through the wholesale electricity market. Mississippi Power continues to manage retail fuel-hedging programs implemented per the guidelines of the Mississippi PSC and wholesale fuel-hedging programs under agreements with wholesale customers. As such, Mississippi Power had no material change in market risk exposure for the third quarter 2012 when compared with the December 31, 2011 reporting period.

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The changes in fair value of energy-related derivative contracts, substantially all of which are composed of regulatory hedges, for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(37	)	$	(51	)
Contracts realized or settled	13			39
Current period changes(a)	9			(3		)
Contracts outstanding at the end of the period, assets (liabilities), net	$	(15	)	$	(15	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

The changes in the fair value positions of the energy-related derivative contracts, which are substantially all attributable to both the volume and the price of natural gas, for the three and nine months ended September 30, 2012 were as follows: 

	Third Quarter 2012 Changes		Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Natural gas swaps	$	18	$	29
Natural gas options	4		7
Total changes	$	22	$	36

The net hedge volumes of energy-related derivative contracts were as follows:

	September 30, 2012	June 30, 2012	December 31, 2011
	mmBtu Volume
	(in millions)
Commodity – Natural gas swaps	33	29	22
Commodity – Natural gas options	2	5	9
Total hedge volume	35	34	31

The weighted average swap contract cost above market prices was approximately $0.42 per mmBtu as of September 30, 2012, $1.08 per mmBtu as of June 30, 2012, and $1.98 per mmBtu as of December 31, 2011. The change in option premiums is primarily attributable to the volatility of the market and the underlying change in the natural gas price. The majority of the costs associated with natural gas hedges are recovered through Mississippi Power's energy cost management clause (ECM).

Regulatory hedges relate to Mississippi Power's fuel-hedging program where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through Mississippi Power's ECM.

Unrealized pre-tax gains and losses recognized in income for the three and nine months ended September 30, 2012 and 2011 for energy-related derivative contracts that are not hedges were not material.

136

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Mississippi Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows:

				September 30, 2012 Fair Value Measurements
	Total			Maturity
	Fair Value			Year 1			Years 2&3			Years 4&5
	(in millions)
Level 1	$	—		$	—		$	—		$	—
Level 2	(15		)	(11		)	(4		)	—
Level 3	—			—			—			—
Fair value of contracts outstanding at end of period	$	(15	)	$	(11	)	$	(4	)	$	—

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Mississippi Power. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Mississippi Power and its derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Mississippi Power does not expect the impact of these rules to be material.

For additional information, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" of Mississippi Power in Item 7 and Note 1 under "Financial Instruments" and Note 10 to the financial statements of Mississippi Power in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein.

Financing Activities

In March 2012, Mississippi Power issued $250 million aggregate principal amount of Series 2012A 4.25% Senior Notes due March 15, 2042 and an additional $150 million aggregate principal amount of Series 2011A 2.35% Senior Notes due October 15, 2016. The Series 2011A Senior Notes were of the same series of notes that were originally issued in October 2011 in the aggregate principal amount of $150 million. Upon completion of this offering, the aggregate principal amount of the outstanding Series 2011A Senior Notes was $300 million. The proceeds from the sales of the Series 2012A Senior Notes and the Series 2011A Senior Notes were used to repay a bank loan in an aggregate principal amount of $75 million and for general corporate purposes, including Mississippi Power's continuous construction program.

In March 2012, $300 million in interest rate swaps were settled, of which $250 million related to the Series 2012A Senior Notes at a loss of approximately $13.3 million, which will be amortized to interest expense, in earnings, over 10 years, and $50 million related to the Series 2011A Senior Notes at a loss of approximately $2.7 million, which will be amortized to interest expense, in earnings, over 10 years.

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the sale price for the pending sale of an undivided interest in the Kemper IGCC. Until the acquisition is closed, the deposit bears interest at Mississippi Power's AFUDC rate adjusted for income taxes, which was 9.967%per annum at September 30, 2012, and is refundable to SMEPA upon termination of the asset purchase agreement related to such purchase, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies.

In May 2012, Mississippi Power redeemed $90 million aggregate principal amount of Series E 5-5/8% Senior Notes due May 1, 2033.

137

MISSISSIPPI POWER COMPANY

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In August 2012, Mississippi Power issued an additional $200 million aggregate principal amount of Series 2012A 4.25% Senior Notes due March 15, 2042. The Series 2012A Senior Notes were of the same series of notes that were originally issued in March 2012 in the aggregate principal amount of $250 million. Upon completion of this offering, the aggregate principal amount of the outstanding Series 2012A Senior Notes is $450 million. The proceeds from this sale of the Series 2012A Senior Notes were used for general corporate purposes, including Mississippi Power's continuous construction program.

In August 2012, the Mississippi Business Finance Corporation entered into an agreement to issue up to $42.5 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012A (Mississippi Power Company Project), up to $21.25 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012B (Mississippi Power Company Project), and up to $21.25 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds, Series 2012C (Mississippi Power Company Project) for the benefit of Mississippi Power. In August 2012, the Mississippi Business Finance Corporation issued $4.36 million aggregate principal amount of Mississippi Business Finance Corporation Taxable Revenue Bonds (Mississippi Power Company Project), Series 2012B and $21.25 million aggregate principal amount of Revenue Bonds (Mississippi Power Company Project), Series 2012C for the benefit of Mississippi Power. The proceeds were used to reimburse Mississippi Power for the cost of the acquisition, construction, equipping, installation, and improvement of certain equipment and facilities for the lignite mining facility related to the Kemper IGCC. Any future issuances of these bonds will be used for this same purpose.

In September 2012, Mississippi Power paid at maturity a $40 million aggregate principal amount floating rate bank note.

In September 2012, Mississippi Power entered into a 366-day extension of a $125 million aggregate principal amount floating rate bank loan that bears interest based on one-month LIBOR.

In addition to any financings that may be necessary to meet capital requirements and contractual obligations, Mississippi Power plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-cost capital if market conditions permit.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER 2012 vs. THIRD QUARTER 2011

AND

YEAR-TO-DATE 2012 vs. YEAR-TO-DATE 2011

OVERVIEW

Southern Power and its subsidiaries construct, acquire, own, and manage generation assets, including renewable energy projects, and sell electricity at market-based prices in the wholesale market. Southern Power continues to execute its strategy through a combination of acquiring and constructing new power plants and by entering into PPAs primarily with investor owned utilities, independent power producers, municipalities, and electric cooperatives. In accordance with this overall growth strategy, the Nacogdoches Power, LLC (Nacogdoches) biomass plant began commercial operation on June 22, 2012. See FUTURE EARNINGS POTENTIAL – "Construction Projects" herein for additional information. In 2012, Southern Power and Turner Renewable Energy, Inc. (TRE), through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Apex Nevada Solar, LLC (Apex), Spectrum Nevada Solar, LLC (Spectrum), and Granville Solar, LLC (Granville). Upon completion of construction, these projects will add a total of 47 MWs of solar capacity to the Southern Power generation portfolio. The acquisitions are in accordance with Southern Power's overall growth strategy. See FUTURE EARNINGS POTENTIAL – "Acquisitions" herein for additional information.

To evaluate operating results and to ensure Southern Power's ability to meet its contractual commitments to customers, Southern Power focuses on several key performance indicators. These indicators include peak season equivalent forced outage rate (Peak Season EFOR), contract availability, and net income. Peak Season EFOR defines the hours during peak demand times when Southern Power's generating units are not available due to forced outages (the lower the better). Contract availability measures the percentage of scheduled hours that a unit was available. Net income is the primary measure of Southern Power's financial performance. For additional information on these indicators, see MANAGEMENT'S DISCUSSION AND ANALYSIS – OVERVIEW – "Key Performance Indicators" of Southern Power in Item 7 of the Form 10-K.

RESULTS OF OPERATIONS

Net Income

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$12.3	21.9	$5.9	4.2

Southern Power's net income for the third quarter 2012 was $68.4 million compared to $56.1 million for the corresponding period in 2011. The increase was primarily due to an increase in energy revenues from sales to affiliates under the IIC, an increase in capacity revenues due to an increase in total MWs of capacity under long-term contracts, lower fuel and purchased power expenses, and lower interest expense. The increase was partially offset by a decrease in energy revenues from non-affiliates and increased depreciation.

Southern Power's net income for year-to-date 2012 was $144.3 million compared to $138.4 million for the corresponding period in 2011. The increase was primarily due to an increase in energy revenues from sales to affiliates under the IIC, an increase in capacity revenues due to an increase in total MWs of capacity under long-term contracts, lower fuel and purchased power expenses, and lower interest expense. The increase was partially offset by a decrease in energy revenues from non-affiliates, an increase in other operations and maintenance expenses, and increased depreciation.

Wholesale Revenues–Non-Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$(35.1)	(12.8)	$(146.8)	(20.8)

Wholesale energy sales to non-affiliates will vary depending on the energy demand of those customers and their generation capacity, as well as the market prices of wholesale energy compared to the cost of Southern Power's energy. Increases and decreases in revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income.

Wholesale revenues from non-affiliates for the third quarter 2012 were $239.9 million compared to $275.0 million for the corresponding period in 2011. The decrease was primarily due to a $57.1 million decrease in energy sales, reflecting a 28.1% decrease in the average price of energy and a 5.4% decrease in KWH sales. The decrease in revenue from energy sales was partially offset by a $22.1 million increase in capacity revenue due to an increase in the total MWs of capacity under contract with non-affiliates.

Wholesale energy sales to non-affiliates for year-to-date 2012 were $558.3 million compared to $705.1 million for the corresponding period in 2011. The decrease was primarily due to a $178.4 million decrease in energy sales, reflecting a 36.4% decrease in the average price of energy and a 4.6% decrease in KWH sales. The decrease in revenue from energy sales was partially offset by a $31.6 million increase in capacity revenue due to an increase in the total MWs of capacity under contract with non-affiliates.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Power Sales Agreements" of Southern Power in Item 7 of the Form 10-K for additional information.

Wholesale Revenues–Affiliates

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$27.5	32.3	$91.4	38.2

Wholesale energy sales to affiliated companies within the Southern Company system will vary depending on demand and the availability and cost of generating resources at each company. Sales to affiliate companies that are not covered by PPAs are made in accordance with the IIC, as approved by the FERC.

Wholesale revenues from affiliates for the third quarter 2012 were $112.7 million compared to $85.2 million for the corresponding period in 2011. The increase was the result of a $27.5 million increase in energy sales under the IIC, reflecting a 121.1% increase in KWH sales resulting from the availability of Southern Power's lower priced natural gas resources to serve affiliate demand, partially offset by a 25.5% reduction in the average price of energy.

Wholesale revenues from affiliates for year-to-date 2012 were $330.4 million compared to $239.0 million for the corresponding period in 2011. The increase was primarily the result of a $114.7 million increase in energy sales under the IIC, reflecting a 252.7% increase in KWH sales resulting from the availability of Southern Power's lower priced natural gas resources to serve affiliate demand, partially offset by a 36.6% reduction in the average price of energy. The increase in revenue from energy sales was partially offset by a $20.6 million decrease in capacity revenue due to a decrease in total MWs of capacity under contract with affiliates.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Fuel and Purchased Power Expenses

	Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
	(change in millions)	(% change)	(change in millions)	(% change)
Fuel	$(15.9)	(11.2)	$(39.1)	(11.3)
Purchased power – non-affiliates	(1.3)	(5.1)	13.3	24.7
Purchased power – affiliates	(8.8)	(76.8)	(40.8)	(83.8)
Total fuel and purchased power expenses	$(26.0)		$(66.6)

Southern Power PPAs generally provide that the purchasers are responsible for substantially all of the cost of fuel. Consequently, any increase or decrease in fuel costs is generally accompanied by an increase or decrease in related fuel revenues and does not have a significant impact on net income. Southern Power is responsible for the cost of fuel for generating units that are not covered under PPAs. Power from these generating units is sold into the market or sold to affiliates under the IIC.

Purchased power expenses will vary depending on demand and the availability and cost of generating resources throughout the Southern Company system and other available contract resources. Load requirements are submitted to the Power Pool on an hourly basis and are fulfilled with the lowest cost alternative, whether that is generation owned by Southern Power, affiliate-owned generation, or external purchases.

In the third quarter 2012, total fuel and purchased power expenses were $152.6 million compared to $178.6 million for the corresponding period in 2011. Fuel and purchased power expenses decreased $48.0 million due to a 22.7% decrease in the average cost of fuel and a 24.9% decrease in the average cost of purchased power. The decrease was partially offset by a $22.1 million increase associated with a 12.2% net increase in the volume of KWHs generated and purchased.

For year-to-date 2012, total fuel and purchased power expenses were $381.7 million compared to $448.3 million for the corresponding period in 2011. Fuel and purchased power expenses decreased $192.8 million due to a 34.8% decrease in the average cost of fuel and a 25.7% decrease in the average cost of purchased power. The decrease was partially offset by a $126.2 million increase associated with a 29.4% net increase in the volume of KWHs generated and purchased.

In the third quarter 2012, fuel expense was $126.1 million compared to $142.0 million for the corresponding period in 2011. The decrease was due to a $39.2 million decrease associated with the cost of fuel, partially offset by a $23.3 million increase associated with the volume of KWHs generated.

For year-to-date 2012, fuel expense was $306.7 million compared to $345.8 million for the corresponding period in 2011. The decrease was due to a $167.0 million decrease associated with the cost of fuel, partially offset by a $127.9 million increase associated with the volume of KWHs generated.

In the third quarter 2012, purchased power expenses were $26.5 million compared to $36.6 million for the corresponding period in 2011. The decrease was due to an $8.8 million decrease associated with the cost of purchased power and a $1.2 million decrease associated with the volume of KWHs purchased.

For year-to-date 2012, purchased power expenses were $75.0 million compared to $102.5 million for the corresponding period in 2011. The decrease was due to a $25.8 million decrease associated with the cost of purchased power and a $1.7 million decrease associated with the volume of KWHs purchased.

(change in millions)	(% change)	(change in millions)	(% change)
$0.8	2.0	$6.6	5.4

In the third quarter 2012, other operations and maintenance expenses were $40.4 million compared to $39.6 million for the corresponding period in 2011. The change in operations and maintenance expense was not material.

For year-to-date 2012, other operations and maintenance expenses were $129.0 million compared to $122.4 million for the corresponding period in 2011. The increase was primarily due to a $5.4 million increase in administrative and general expenses due to increases in business development expenses and affiliate service company expense allocated based on load and fuel burn and a $1.5 million increase in transmission cost.

Depreciation and Amortization

Third Quarter 2012 vs. Third Quarter 2011		Year-to-Date 2012 vs. Year-to-Date 2011
(change in millions)	(% change)	(change in millions)	(% change)
$6.0	19.2	$11.0	11.9

In the third quarter 2012, depreciation and amortization was $37.6 million compared to $31.6 million for the corresponding period in 2011. The increase was primarily due to a $6.7 million increase in depreciation resulting from an increase in plant in service, including the addition of the Nacogdoches biomass plant and the Apex solar facility, and a $0.6 million increase due to higher depreciation rates from a depreciation study adopted in January 2012, partially offset by a $1.2 million decrease in depreciation related to asset retirements.

For year-to-date 2012, depreciation and amortization was $103.5 million compared to $92.5 million for the corresponding period in 2011. The increase was primarily due to a $9.3 million increase in depreciation resulting from an increase in plant in service, including the addition of the Nacogdoches biomass plant and the Apex solar facility, and a $2.3 million increase due to higher depreciation rates from a depreciation study adopted in January 2012, partially offset by a $0.6 million decrease in depreciation related to asset retirements.

Interest Expense, Net of Amounts Capitalized

(change in millions)	(% change)	(change in millions)	(% change)
$(2.7)	(13.5)	$(11.7)	(20.7)

In the third quarter 2012, interest expense, net of amounts capitalized was $17.2 million compared to $19.9 million for the corresponding period in 2011. The decrease was primarily due to a $2.6 million expense reduction associated with the refinancing of $575 million in long-term debt in 2011 and a $0.2 million increase in capitalized interest, as compared to amounts recognized in the corresponding period in 2011, associated with the construction of the Cleveland County combustion turbine generating plant and the Nacogdoches biomass plant.

For year-to-date 2012, interest expense, net of amounts capitalized was $44.8 million compared to $56.5 million for the corresponding period in 2011. The decrease was primarily due to a $7.0 million expense reduction associated with the refinancing of $575 million in long-term debt in 2011 and a $4.3 million increase in capitalized interest associated with the construction of the Cleveland County combustion turbine generating plant and the Nacogdoches biomass plant.

(change in millions)	(% change)	(change in millions)	(% change)
$0.5	1.6	$(1.8)	(2.3)

In the third quarter 2012, income taxes were $33.1 million compared to $32.6 million for the corresponding period in 2011. The increase was primarily due to a $4.7 million increase associated with higher pre-tax earnings, partially offset by a $3.2 million decrease related to an increase in investment tax credits (ITCs) recognized, primarily associated with the acquisition of Apex, and a $1.2 million decrease due to an increase in state ITCs as compared to the corresponding period in 2011.

For year-to-date 2012, income taxes were $75.8 million compared to $77.6 million for the corresponding period in 2011. The decrease was primarily due to a $2.2 million decrease due to the conclusion of prior year IRS audits and a $2.0 million decrease related to an increase in ITCs recognized, partially offset by a $0.5 million increase associated with higher pre-tax earnings and a $1.6 million increase in Alabama state income taxes due to a decrease in the state income tax deduction for federal income taxes paid.

FUTURE EARNINGS POTENTIAL

The results of operations discussed above are not necessarily indicative of Southern Power's future earnings potential. The level of Southern Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Southern Power's competitive wholesale business. These factors include: Southern Power's ability to achieve sales growth while containing costs; regulatory matters; creditworthiness of customers; total generating capacity available in Southern Power's target market areas; the successful remarketing of capacity as current contracts expire; and Southern Power's ability to execute its acquisition strategy and to construct generating facilities. Other factors that could influence future earnings include weather, demand, generation patterns, and operational limitations. General economic conditions have lowered demand and have negatively impacted capacity revenues under Southern Power's PPAs where the amounts purchased are based on demand. Southern Power is unable to predict whether demand under these PPAs will return to pre-recession levels. The timing and extent of the economic recovery is uncertain and may impact future earnings. For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL of Southern Power in Item 7 of the Form 10-K.

Environmental Matters

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" of Southern Power in Item 7 of the Form 10-K for information on the development by federal and state environmental regulatory agencies of additional control strategies for emissions of air pollution from industrial sources, including electric generating facilities. Compliance with possible additional federal or state legislation or regulations related to global climate change, air quality, or other environmental and health concerns could also significantly affect Southern Power. While Southern Power's PPAs generally contain provisions that permit charging the counterparty with some of the new costs incurred as a result of changes in environmental laws and regulations, the full impact of any such regulatory or legislative changes cannot be determined at this time.

Global Climate Issues

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters – Global Climate Issues" of Southern Power in Item 7 of the Form 10-K for additional information.

On April 13, 2012, the EPA published proposed regulations to establish standards of performance for greenhouse gas emissions from new fossil fuel steam electric generating units. As proposed, the standards would not apply to existing units. The EPA has delayed its plans to propose greenhouse gas emissions performance standards for modified sources and emissions guidelines for existing sources. The impact of this rulemaking will depend on the scope and specific requirements of the final rule and the outcome of any legal challenges and, therefore, cannot be determined at this time.

On June 26, 2012, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit unanimously rejected all challenges to four of the EPA's actions relating to the greenhouse gas permitting programs under the Clean Air Act. These rules may impact the amount of time it takes to obtain prevention of significant deterioration permits for new generation and major modifications to existing generating units and the requirements ultimately imposed by those permits. The ultimate impact of these rules cannot be determined at this time and will depend on the outcome of any other legal challenges.

Income Tax Matters

Bonus Depreciation

In December 2010, the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 (Tax Relief Act) was signed into law. Major tax incentives in the Tax Relief Act include 100% bonus depreciation for property placed in service after September 8, 2010 and through 2011 (and for certain long-term construction projects to be placed in service in 2012) and 50% bonus depreciation for property placed in service in 2012 (and for certain long-term construction projects to be placed in service in 2013), which will have a positive impact on the future cash flows of Southern Power through 2013. Consequently, Southern Power's positive cash flow benefit is estimated to be between $180 million and $210 million in 2012.

Acquisitions

Apex Nevada Solar, LLC Acquisition

On June 29, 2012, Southern Power and TRE, through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Apex from Sun Edison, LLC, the original developer of the project. Apex constructed and owns a 20-MW solar photovoltaic facility in North Las Vegas, Nevada. The solar facility began commercial operation on July 21, 2012. The output of the plant is contracted under a 25-year PPA with Nevada Power Company, a subsidiary of NV Energy, Inc., that began in July 2012. See Note (I) to the Condensed Financial Statements herein for additional information.

Spectrum Nevada Solar, LLC Acquisition

On September 28, 2012, Southern Power and TRE, through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Spectrum from Sun Edison, LLC, the original developer of the project. Spectrum is constructing a 30-MW solar photovoltaic facility in North Las Vegas, Nevada. The solar facility is expected to begin commercial operation in April 2013. The output of the plant is contracted under a 25-year PPA with Nevada Power Company, a subsidiary of NV Energy, Inc., that will begin in 2013. See Note (I) to the Condensed Financial Statements herein for additional information.

Granville Solar, LLC Acquisition

On October 16, 2012, Southern Power and TRE, through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Granville from Sun Edison, LLC, the original developer of the project. Granville constructed and owns a 2.5-MW solar photovoltaic facility in Oxford, North Carolina. Commercial operation of the solar facility was declared by Granville on October 28, 2012. The output of the plant is contracted under a 20-year PPA with Progress Energy Carolinas that began in October 2012. See Note (I) to the Condensed Financial Statements herein for additional information.

Construction Projects

Cleveland County Units 1-4

In 2008, Southern Power announced plans to build an electric generating plant in Cleveland County, North Carolina. The plant will consist of four combustion turbine natural gas generating units with a total generating capacity of 720 MWs. The units are expected to begin commercial operation in December 2012. Construction costs incurred through September 30, 2012 were $311.9 million. The total estimated cost of the project is expected to be between $330 million and $345 million.

Nacogdoches Biomass Plant

In 2009, Southern Power acquired all of the outstanding membership interests of Nacogdoches from American Renewables LLC, the original developer of the project. Nacogdoches constructed a biomass generating plant in Sacul, Texas with an estimated capacity of 100 MWs. The generating plant is fueled from wood waste. The plant began commercial operation on June 22, 2012. Project costs incurred through September 30, 2012 were $459.4 million. The final cost of the project is expected to be between $460 million and $465 million.

Power Sales Agreements

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Power Sales Agreements" of Southern Power in Item 7 of the Form 10-K for additional information regarding Southern Power's PPAs with investor-owned utilities, independent power purchasers, municipalities, and electric cooperatives.

In June 2011, Southern Power entered into three PPAs with Georgia Power subject to Georgia PSC and FERC approval. These PPAs were approved by the Georgia PSC on March 20, 2012 and are still subject to approval by the FERC. The ultimate outcome of this matter cannot be determined at this time.

On June 29, 2012, a subsidiary of Southern Power assumed the PPA with Nevada Power Company in connection with the acquisition of Apex. Commercial operation began on July 21, 2012.

On September 7, 2012, Southern Power entered into two PPAs with Jackson Electric Membership Corporation and Greystone Power Corporation to sell 65 MWs and 40 MWs, respectively, from January 2016 through December 2035 from Plant Franklin.

On September 28, 2012, a subsidiary of Southern Power assumed the PPA with Nevada Power Company in connection with the acquisition of Spectrum. The solar facility is expected to begin commercial operation in April 2013.

On October 16, 2012, a subsidiary of Southern Power assumed the PPA with Progress Energy Carolinas in connection with the acquisition of Granville. Commercial operation was declared by Granville on October 28, 2012.

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Other Matters

Southern Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In addition, Southern Power is subject to certain claims and legal actions arising in the ordinary course of business. Southern Power's business activities are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against Southern Power and its subsidiaries cannot be predicted at this time; however, for current proceedings not specifically reported in Note (B) herein or in Note 3 to the financial statements of Southern Power in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Southern Power's financial statements.

See the Notes to the Condensed Financial Statements herein for a discussion of various other contingencies and other matters being litigated which may affect future earnings potential.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

Southern Power prepares its consolidated financial statements in accordance with GAAP. Significant accounting policies are described in Note 1 to the financial statements of Southern Power in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on Southern Power's results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" of Southern Power in Item 7 of the Form 10-K for a complete discussion of Southern Power's critical accounting policies and estimates related to Revenue Recognition, Impairment of Long Lived Assets and Intangibles, Acquisition Accounting, Contingent Obligations, Depreciation, and Convertible Investment Tax Credits.

FINANCIAL CONDITION AND LIQUIDITY

Overview

Southern Power's financial condition remained stable at September 30, 2012. Southern Power intends to continue to monitor its access to short-term and long-term capital markets as well as its bank credit arrangements as needed to meet future capital and liquidity needs. See "Sources of Capital" herein for additional information on lines of credit.

Net cash provided from operating activities totaled $446.3 million for the first nine months of 2012, an increase of $118.1 million as compared to the first nine months of 2011. The increase in cash provided from operating activities was primarily due to an increase in deferred income taxes, partially offset by a decrease in cash received for ITCs. Net cash used for investing activities totaled $281.3 million for the first nine months of 2012 primarily due to the Apex and Spectrum acquisitions, gross property additions related to construction activities at Cleveland County, and payments pursuant to long-term service agreements. Net cash used for financing activities totaled $165.9 million for the first nine months of 2012 primarily due to payment of common stock dividends and a decrease in notes payable in 2012. Fluctuations in cash flow from financing activities vary year to year based on capital needs and the maturity or redemption of securities.

152

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Significant asset changes in the balance sheet for the first nine months of 2012 include: a $13.7 million increase in customer accounts receivable from non-affiliated companies and an $11.9 million increase in accounts receivable from affiliated companies primarily due to the seasonality in PPAs; a $37.6 million increase in prepaid service agreements–current due to the timing of plant outages; and a $122.4 million increase in total property, plant, and equipment primarily due to the acquisitions of Apex and Spectrum.

Significant liability and stockholder's equity changes in the balance sheet for the first nine months of 2012 include a $149.1 million increase in accumulated deferred income taxes primarily due to bonus depreciation.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" of Southern Power in Item 7 of the Form 10-K for a description of Southern Power's capital requirements for its construction program, scheduled maturities of long-term debt, interest, leases, derivative obligations, purchase commitments, and long-term service agreements. There are no requirements through September 30, 2013 to fund maturities of long-term debt.

The construction program is subject to periodic review and revision; these amounts include estimates for potential plant acquisitions and new construction as well as ongoing capital improvements and work to be performed under long-term service agreements. Planned expenditures for plant acquisitions may vary due to market opportunities and Southern Power's ability to execute its growth strategy. Actual construction costs may vary from these estimates because of changes in factors such as: business conditions; environmental statutes and regulations; FERC rules and regulations; load projections; legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; and the cost of capital.

Sources of Capital

Southern Power may use operating cash flows, external funds, or equity capital or loans from Southern Company to finance any new projects, acquisitions, and ongoing capital requirements. Southern Power expects to generate external funds from the issuance of unsecured senior debt and commercial paper or utilization of credit arrangements from banks. However, the amount, type, and timing of any future financings, if needed, will depend upon prevailing market conditions, regulatory approval, and other factors. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" of Southern Power in Item 7 of the Form 10-K for additional information.

Southern Power's current liabilities frequently exceed current assets due to the use of short-term debt as a funding source, as well as cash needs which can fluctuate significantly due to the seasonality of the business. To meet liquidity and capital resource requirements, Southern Power had at September 30, 2012 cash and cash equivalents of approximately $16.1 million and a committed credit facility of $500 million (Facility) expiring in 2016. The Facility contains a covenant that limits the ratio of debt to capitalization (each as defined in the Facility) to a maximum of 65% and contains a cross default provision that is restricted only to the indebtedness of Southern Power. Southern Power is currently in compliance with all such covenants. Proceeds from this Facility may be used for working capital and general corporate purposes as well as liquidity support for Southern Power's commercial paper program. See Note 6 to the financial statements of Southern Power under "Bank Credit Arrangements" in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.

Southern Power's commercial paper program is used to finance acquisition and construction costs related to electric generating facilities and for general corporate purposes.

153

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Details of short-term borrowings were as follows: 

	Short-term Debt at September 30, 2012				Short-term Debt During the Period (a)
	Amount Outstanding		Weighted Average Interest Rate		Average Outstanding		Weighted Average Interest Rate		Maximum Amount Outstanding
	(in millions)				(in millions)				(in millions)
Commercial paper	$	101	0.5	%	$	240	0.5	%	$	309

(a) Average and maximum amounts are based upon daily balances during the three month period ended September 30, 2012.

In addition, $0.9 million in anticipated prepayment of notes payable to TRE has been reclassified as short-term debt.

Management believes that the need for working capital can be adequately met by utilizing the commercial paper program, the Facility, and cash.

Credit Rating Risk

Southern Power does not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to BBB and Baa2, or BBB- and/or Baa3 or below. These contracts are for physical electricity purchases and sales, fuel transportation and storage, and energy price risk management.

The maximum potential collateral requirements under these contracts at September 30, 2012 were as follows:

Credit Ratings	Maximum Potential Collateral Requirements
	(in millions)
At BBB and Baa2	$	9
At BBB- and/or Baa3	478
Below BBB- and/or Baa3	1,229

Included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, any credit rating downgrade could impact Southern Power's ability to access capital markets, particularly the short-term debt market.

In addition, through the acquisition of Plant Rowan, Southern Power assumed a PPA with North Carolina Municipal Power Agency No. 1 that could require collateral, but not accelerated payment, in the event of a downgrade of Southern Power's credit. The PPA requires credit assurances without stating a specific credit rating. The amount of collateral required would depend upon actual losses, if any, resulting from a credit downgrade.

Market Price Risk

Southern Power is exposed to market risks, including changes in interest rates, certain energy-related commodity prices, and, occasionally, currency exchange rates. To manage the volatility attributable to these exposures, Southern Power takes advantage of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to Southern Power's policies in areas such as counterparty exposure and risk management practices. Southern Power's policy is that derivatives are to be used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress tests, and sensitivity analysis.

154

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Southern Power's market risk exposure relative to interest rate changes for the third quarter 2012 has not changed materially compared with the December 31, 2011 reporting period. Since a significant portion of outstanding indebtedness bears interest at fixed rates, Southern Power is not aware of any facts or circumstances that would significantly affect exposure on existing indebtedness in the near term. However, the impact on future financing costs cannot now be determined.

Because energy from Southern Power's facilities is primarily sold under long-term PPAs with tolling agreements and provisions shifting substantially all of the responsibility for fuel cost to the counterparties, Southern Power's exposure to market volatility in commodity fuel prices and prices of electricity is generally limited. However, Southern Power has been and may continue to be exposed to market volatility in energy-related commodity prices as a result of sales of uncontracted generating capacity.

The changes in fair value of energy-related derivative contracts for the three and nine months ended September 30, 2012 were as follows:

	Third Quarter 2012 Changes			Year-to-Date 2012 Changes
	Fair Value
	(in millions)
Contracts outstanding at the beginning of the period, assets (liabilities), net	$	(5.7	)	$	(9.2	)
Contracts realized or settled	4.9			14.1
Current period changes(a)	0.7			(5.0		)
Contracts outstanding at the end of the period, assets (liabilities), net	$	(0.1	)	$	(0.1	)

(a) Current period changes also include the changes in fair value of new contracts entered into during the period, if any.

The changes in the fair value positions of the energy-related derivative contracts for the three and nine months ended September 30, 2012 were an increase of $5.6 million and $9.1 million, respectively, which are due to both power and natural gas positions. The changes are attributable to both the volume and prices of power and natural gas as follows:

	September 30, 2012			June 30, 2012		December 31, 2011
Power – net purchased or (sold)
MWHs (in millions)	(0.1		)	—		0.1
Weighted average contract cost per MWH above (below) market prices (in dollars)	$	1.03		$	—	$	(1.04	)
Natural gas net purchased
Commodity – million mmBtu	9.1			18.3		8.3
Commodity – weighted average contract cost per mmBtu above (below) market prices (in dollars)	$	0.02		$	0.83	$	1.18

The fair value of energy-related derivative contracts by hedge designation reflected in the financial statements as assets (liabilities) consists of the following:

Asset (Liability) Derivatives	September 30, 2012			December 31, 2011
	(in millions)
Cash flow hedges	$	(0.6	)	$	(0.8	)
Not designated	0.5			(8.4		)
Total fair value	$	(0.1	)	$	(9.2	)

155

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Gains and losses on energy-related derivatives used by Southern Power to hedge anticipated purchases and sales are initially deferred in OCI before being recognized in income in the same period as the hedged transaction. Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

Total net unrealized pre-tax gains (losses) recognized in the statements of income for the three and nine months ended September 30, 2012 for energy-related derivative contracts that were not hedges were $5.1 million and $9.0 million, respectively, and will continue to be marked to market until the settlement date. These gains, which are associated with hedging fuel price risk of certain PPA customers, have no impact on net income, as the amounts are credited back to the customers. For the three and nine months ended September 30, 2011, the total net unrealized pre-tax gains (losses) recognized in the statements of income for energy-related derivative contracts that were not hedges were $(0.6) million and $(1.5) million, respectively. Included in these amounts are amounts reimbursable by third parties of $1.0 million and $1.2 million, respectively.

Southern Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market observable, and thus fall into Level 2. See Note (C) to the Condensed Financial Statements herein for further discussion on fair value measurements. The maturities of the energy-related derivative contracts and the level of the fair value hierarchy in which they fall at September 30, 2012 were as follows:

				September 30, 2012 Fair Value Measurements
	Total			Maturity
	Fair Value			Year 1			Years 2&3		Years 4&5
	(in millions)
Level 1	$	—		$	—		$	—	$	—
Level 2	(0.1		)	(0.5		)	0.1		0.3
Level 3	—			—			—		—
Fair value of contracts outstanding at end of period	$	(0.1	)	$	(0.5	)	$	0.1	$	0.3

The Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) enacted in July 2010 could impact the use of over-the-counter derivatives by Southern Power. Regulations to implement the Dodd-Frank Act will impose additional requirements on the use of over-the-counter derivatives for both Southern Power and its derivative counterparties, which could affect both the use and cost of over-the-counter derivatives. Although all relevant regulations have not been finalized, Southern Power does not expect the impact of these rules to be material.

For additional information, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" of Southern Power in Item 7 and Note 1 under "Financial Instruments" and Note 9 to the financial statements of Southern Power in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein.

Financing Activities

During the nine months ended September 30, 2012, Southern Power prepaid $0.6 million of long-term debt to TRE.

In June 2012, Southern Power issued a $3.6 million promissory note, due June 15, 2032, to TRE related to the financing of Apex. An additional $0.5 million was issued in September 2012 based on the completion of a project milestone.

156

SOUTHERN POWER COMPANY AND SUBSIDIARY COMPANIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

In September 2012, Southern Power issued a $0.9 million promissory note, due September 30, 2032, to TRE related to the financing of Spectrum.

Subsequent to September 30, 2012, Southern Power issued a $0.5 million promissory note, due October 31, 2032, to TRE related to the financing of Granville.

In addition to any financings that may be necessary to meet capital requirements and contractual obligations, Southern Power plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-cost capital if market conditions permit.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS:

(A) INTRODUCTION

The condensed quarterly financial statements of each registrant included herein have been prepared by such registrant, without audit, pursuant to the rules and regulations of the SEC. The Condensed Balance Sheets as of December 31, 2011 have been derived from the audited financial statements of each registrant. In the opinion of each registrant's management, the information regarding such registrant furnished herein reflects all adjustments, which, except as otherwise disclosed, are of a normal recurring nature, necessary to present fairly the results of operations for the periods ended September 30, 2012 and 2011. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although each registrant believes that the disclosures regarding such registrant are adequate to make the information presented not misleading. Disclosures which would substantially duplicate the disclosures in the Form 10-K and details which have not changed significantly in amount or composition since the filing of the Form 10-K are generally omitted from this Quarterly Report on Form 10-Q. Therefore, these Condensed Financial Statements should be read in conjunction with the financial statements and the notes thereto included in the Form 10-K. Due to the seasonal variations in the demand for energy, operating results for the periods presented are not necessarily indicative of the operating results to be expected for the full year.

Certain prior year data presented in the financial statements have been reclassified to conform to the current year presentation.

Investments in Leveraged Leases

See Note 1 to the financial statements of Southern Company under "Leveraged Leases" in Item 8 of the Form 10-K for additional information.

The recent financial and operational performance of one of Southern Company's lessees and the associated generation assets has raised potential concerns on the part of Southern Company as to the credit quality of the lessee and the residual value of the assets. Current projections indicate significant uncertainty as to whether the lessee will be able to pay the December 2012 semi-annual rent payment in full. Southern Company continues to be engaged in discussions with the lessee and the holders of the project's nonrecourse debt to restructure the debt payments and the related rental payments to allow additional capital investment in the project to be made to improve the operation of the generation assets and the financial viability of the lease transaction. Southern Company continues to believe there is a reasonable possibility that it will be able to reach an agreement with the lessee and the debtholders to restructure the project prior to the end of 2012. However, due to continued poor performance of the generation assets and the uncertainties surrounding the receipt of the December 2012 semi-annual rent payment and its ability to successfully restructure the project, Southern Company has placed the lease on nonaccrual status whereby, effective July 2012, income associated with this investment is not recognized in the financial statements. If the attempts at restructuring the project are unsuccessful and the project is ultimately abandoned, the potential impairment loss that would be incurred is approximately $90 million on an after-tax basis. If the restructuring is successfully completed prior to the end of 2012, Southern Company will be required to record a reduction in leveraged lease income of up to approximately $20 million in the fourth quarter 2012. The ultimate outcome of this matter cannot be determined at this time.

159

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

(B) CONTINGENCIES AND REGULATORY MATTERS

See Note 3 to the financial statements of the registrants in Item 8 of the Form 10-K for information relating to various lawsuits, other contingencies, and regulatory matters.

General Litigation Matters

Each registrant is subject to certain claims and legal actions arising in the ordinary course of business. In addition, business activities of Southern Company's subsidiaries are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against each registrant and any subsidiaries cannot be predicted at this time; however, for current proceedings not specifically reported herein or in Note 3 to the financial statements of each registrant in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on such registrant's financial statements.

Insurance Recovery

Mirant Corporation (Mirant) was an energy company with businesses that included independent power projects and energy trading and risk management companies in the U.S. and other countries. Mirant was a wholly-owned subsidiary of Southern Company until its initial public offering in 2000. In 2001, Southern Company completed a spin-off to its stockholders of its remaining ownership, and Mirant became an independent corporate entity.

In 2003, Mirant and certain of its affiliates filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. In 2005, Mirant, as a debtor in possession, and the unsecured creditors' committee filed a complaint against Southern Company. Later in 2005, this complaint was transferred to MC Asset Recovery, LLC (MC Asset Recovery) as part of Mirant's plan of reorganization. In 2009, Southern Company entered into a settlement agreement with MC Asset Recovery to resolve this action. The settlement included an agreement where Southern Company paid MC Asset Recovery $202 million. Southern Company filed an insurance claim in 2009 to recover a portion of this settlement and received a nontaxable $25 million payment from its insurance provider on June 14, 2012. Additionally, legal fees related to this insurance settlement totaled approximately $6 million. As a result, the net reduction to expense for this insurance settlement was approximately $19 million.

Environmental Matters

New Source Review Actions

In 1999, the EPA brought a civil action in the U.S. District Court for the Northern District of Georgia against certain Southern Company subsidiaries, including Alabama Power and Georgia Power, alleging that these subsidiaries had violated the NSR provisions of the Clean Air Act and related state laws at certain coal-fired generating facilities. The EPA alleged NSR violations at five coal-fired generating facilities operated by Alabama Power, including a unit co-owned by Mississippi Power, and three coal-fired generating facilities operated by Georgia Power, including a unit co-owned by Gulf Power. The civil action sought penalties and injunctive relief, including an order requiring installation of the best available control technology at the affected units. The case against Georgia Power (including claims related to the unit co-owned by Gulf Power) was administratively closed in 2001 and has not been reopened. After Alabama Power was dismissed from the original action, the EPA filed a separate action in 2001 against Alabama Power (including claims related to the unit co-owned by Mississippi Power) in the U.S. District Court for the Northern District of Alabama.

160

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

In 2006, the U.S. District Court for the Northern District of Alabama entered a consent decree, resolving claims relating to the alleged NSR violations at Plant Miller. In September 2010, the EPA dismissed five of its eight remaining claims against Alabama Power, leaving only three claims, including one relating to the unit co-owned by Mississippi Power. In March 2011, the U.S. District Court for the Northern District of Alabama granted Alabama Power summary judgment on all remaining claims and dismissed the case with prejudice. That judgment is on appeal to the U.S. Court of Appeals for the Eleventh Circuit. On February 23, 2012, the EPA filed a motion in the U.S. District Court for the Northern District of Alabama seeking vacatur of the judgment and recusal of the judge in the case involving Alabama Power (including claims related to a unit co-owned by Mississippi Power). The U.S. District Court for the Northern District of Alabama has not ruled on the EPA's motion seeking vacatur of the judgment.

Southern Company and each traditional operating company believe each such traditional operating company complied with applicable laws and regulations in effect at the time the work in question took place. The Clean Air Act authorizes maximum civil penalties of $25,000 to $37,500 per day, per violation, depending on the date of the alleged violation. An adverse outcome could require substantial capital expenditures that cannot be determined at this time and could possibly require payment of substantial penalties. Such expenditures could affect future results of operations, cash flows, and financial condition if such costs are not recovered through regulated rates. The ultimate outcome of these matters cannot be determined at this time.

Climate Change Litigation

Kivalina Case

In 2008, the Native Village of Kivalina and the City of Kivalina filed a lawsuit in the U.S. District Court for the Northern District of California against several electric utilities (including Southern Company), several oil companies, and a coal company. The plaintiffs allege that the village is being destroyed by erosion allegedly caused by global warming that the plaintiffs attribute to emissions of greenhouse gases by the defendants. The plaintiffs assert claims for public and private nuisance and contend that some of the defendants (including Southern Company) acted in concert and are therefore jointly and severally liable for the plaintiffs' damages. The suit seeks damages for lost property values and for the cost of relocating the village, which is alleged to be $95 million to $400 million. In 2009, the U.S. District Court for the Northern District of California granted the defendants' motions to dismiss the case. On September 21, 2012, the U.S. Court of Appeals for the Ninth Circuit upheld the U.S. District Court for the Northern District of California's dismissal of the case. On October 8, 2012, the plaintiffs filed for review of the decision by the U.S. Court of Appeals for the Ninth Circuit. Southern Company believes that these claims are without merit. While Southern Company believes the likelihood of loss is remote based on existing case law, it is not possible to predict with certainty whether Southern Company will incur any liability in connection with this matter. The ultimate outcome of this matter cannot be determined at this time.

Hurricane Katrina Case

In 2005, immediately following Hurricane Katrina, a lawsuit was filed in the U.S. District Court for the Southern District of Mississippi by Ned Comer on behalf of Mississippi residents seeking recovery for property damage and personal injuries caused by Hurricane Katrina. In 2006, the plaintiffs amended the complaint to include Southern Company and many other electric utilities, oil companies, chemical companies, and coal producers. The plaintiffs allege that the defendants contributed to climate change, which contributed to the intensity of Hurricane Katrina. In 2007, the U.S. District Court for the Southern District of Mississippi dismissed the case. On appeal to the U.S. Court of Appeals for the Fifth Circuit, a three-judge panel reversed the U.S. District Court for the Southern District of Mississippi, holding that the case could proceed, but, on rehearing, the full U.S. Court of Appeals for the Fifth Circuit dismissed the plaintiffs' appeal, resulting in reinstatement of the decision of the U.S. District Court for the Southern District of Mississippi in favor of the defendants. In May 2011, the plaintiffs filed an amended version of their class action complaint, arguing that the earlier dismissal was on procedural grounds and under Mississippi law

161

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

the plaintiffs have a right to re-file. The amended complaint was also filed against numerous chemical, coal, oil, and utility companies, including Alabama Power, Georgia Power, Gulf Power, and Southern Power. On March 20, 2012, the U.S. District Court for the Southern District of Mississippi dismissed the plaintiffs' amended complaint. On April 16, 2012, the plaintiffs appealed the case to the U.S. Court of Appeals for the Fifth Circuit. Each Southern Company entity named in the lawsuit believes that these claims are without merit. While each Southern Company entity named in the lawsuit believes the likelihood of loss is remote based on existing case law, it is not possible to predict with certainty whether any Southern Company entity named in the lawsuit will incur any liability in connection with this matter. The ultimate outcome of this matter cannot be determined at this time.

Environmental Remediation

The Southern Company system must comply with environmental laws and regulations that cover the handling and disposal of waste and releases of hazardous substances. Under these various laws and regulations, the Southern Company system could incur substantial costs to clean up properties. The traditional operating companies have each received authority from their respective state PSCs to recover approved environmental compliance costs through regulatory mechanisms. These rates are adjusted annually or as necessary within limits approved by the state PSCs.

Georgia Power's environmental remediation liability as of September 30, 2012 was $20 million. Georgia Power has been designated or identified as a potentially responsible party (PRP) at sites governed by the Georgia Hazardous Site Response Act and/or by the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), including a large site in Brunswick, Georgia on the CERCLA National Priorities List (NPL). The parties have completed the removal of wastes from the Brunswick site as ordered by the EPA. Additional cleanup and claims for recovery of natural resource damages at this site or for the assessment and potential cleanup of other sites on the Georgia Hazardous Sites Inventory and the CERCLA NPL are anticipated.

In 2008, the EPA advised Georgia Power that it has been designated as a PRP at the Ward Transformer Superfund site located in Raleigh, North Carolina. Numerous other entities have also received notices regarding this site from the EPA. In September 2011, the EPA issued a unilateral administrative order (UAO) to Georgia Power and 22 other parties, ordering specific remedial action of certain areas at the Ward Transformer Superfund site. Georgia Power does not believe it is a liable party under CERCLA based on its alleged connection to the site. As a result, in November 2011, Georgia Power filed a response with the EPA indicating that Georgia Power is not willing to undertake the work set forth in the UAO because Georgia Power has sufficient cause to believe it is not a liable party. In November 2011, the EPA sent Georgia Power a letter stating that the EPA does not consider Georgia Power to be in compliance with the UAO. The EPA also stated that it is considering enforcement options against Georgia Power and other UAO recipients who are not complying with the UAO. The EPA may seek to enforce the UAO in court pursuant to its enforcement authority under CERCLA and may seek recovery of its costs in undertaking the UAO work. If the court determines that a respondent failed to comply with the UAO without sufficient cause, the EPA may also seek civil penalties of up to $37,500 per day for the violation and punitive damages of up to three times the costs incurred by the EPA as a result of the party's failure to comply with the UAO.

In addition to the EPA's action at the Ward Transformer Superfund site, in 2009, Georgia Power, along with many other parties, was sued by several existing PRPs for cost recovery for a removal action that is currently taking place. Georgia Power and numerous other defendants moved for a dismissal of these lawsuits. The court denied the dismissal of the lawsuits in March 2010 but granted Georgia Power's motion regarding the dismissal of the claim pertaining to the plaintiffs' joint and several liability.

The ultimate outcome of the Brunswick CERCLA NPL and Ward Transformer Superfund site matters will depend upon the success of defenses asserted, the ultimate number of PRPs participating in the cleanup, and numerous other factors and cannot be determined at this time; however, as a result of the regulatory treatment described in Note 1 to the financial statements of Georgia Power under "Environmental Remediation" in Item 8 of the Form 10-K, they are not expected to have a material impact on Southern Company's or Georgia Power's financial statements.

162

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

Gulf Power's environmental remediation liability includes estimated costs of environmental remediation projects of approximately $61 million as of September 30, 2012. These estimated costs primarily relate to site closure criteria by the Florida Department of Environmental Protection (FDEP) for potential impacts to soil and groundwater from herbicide applications at Gulf Power substations. The schedule for completion of the remediation projects is subject to FDEP approval. The projects have been approved by the Florida PSC for recovery through Gulf Power's environmental cost recovery clause; therefore, there was no impact on net income as a result of these estimates.

In 2003, the Texas Commission on Environmental Quality (TCEQ) designated Mississippi Power as a PRP at a site in Texas. The site was owned by an electric transformer company that handled Mississippi Power's transformers as well as those of many other entities. The site owner is bankrupt and the State of Texas has entered into an agreement with Mississippi Power and several other utilities to investigate and remediate the site. The feasibility study/presumptive remedy document was originally filed with TCEQ in June 2011. TCEQ approved the feasibility study on September 17, 2012, but the ultimate remedy to be pursued remains under consideration by the agency. Amounts expensed and accrued related to this work were not material. Hundreds of entities have received notices from the TCEQ requesting their participation in the anticipated site remediation. The final impact of this matter on Mississippi Power will depend upon further environmental assessment and the ultimate number of potentially responsible parties. The remediation expenses incurred by Mississippi Power are expected to be recovered through the ECO Plan.

The final outcome of these matters cannot be determined at this time. However, based on the currently known conditions at these sites and the nature and extent of activities relating to these sites, management of Southern Company, Georgia Power, Gulf Power, and Mississippi Power does not believe that additional liabilities, if any, at these sites would be material to their respective financial statements.

Nuclear Fuel Disposal Cost Litigation

Alabama Power and Georgia Power have contracts with the U.S., acting through the DOE, that provide for the permanent disposal of spent nuclear fuel. The DOE failed to begin disposing of spent nuclear fuel in 1998 as required by the contracts, and Alabama Power and Georgia Power are pursuing legal remedies against the government for breach of contract.

In 2007, the U.S. Court of Federal Claims awarded Georgia Power approximately $30 million, based on its ownership interests, and awarded Alabama Power approximately $17 million, representing substantially all of the Southern Company system's direct costs of the expansion of spent nuclear fuel storage facilities at Plants Farley and Hatch and Plant Vogtle Units 1 and 2 from 1998 through 2004.

In 2008, the government filed an appeal and, in March 2011, the U.S. Court of Appeals for the Federal Circuit issued an order in which it affirmed the damage award to Alabama Power, but remanded the Georgia Power portion of the proceeding back to the U.S. Court of Federal Claims for reconsideration of the damages amount in light of the spent nuclear fuel acceptance rates adopted in a separate proceeding by the U.S. Court of Appeals for the Federal Circuit. In July 2011, the court entered final judgment in favor of Alabama Power and awarded Alabama Power approximately $17 million. In April 2012, the award was credited to cost of service for the benefit of Alabama Power customers.

On April 5, 2012, Georgia Power and the government entered into a stipulation to conclude this litigation, which provided for judgment in favor of Georgia Power and awarded Georgia Power approximately $27 million in damages, based on its ownership interests. On April 5, 2012, the stipulation was approved by the U.S. Court of Federal Claims. The proceeds were received and credited to the Georgia Power accounts where the original costs were charged and were used to reduce rate base, fuel, and cost of service for the benefit of Georgia Power customers.

163

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

In 2008, a second claim against the government was filed for damages incurred after December 31, 2004 (the court-mandated cut-off in the original claim) due to the government's alleged continuing breach of contract. The complaint does not contain any specific dollar amount for recovery of damages. Damages will continue to accumulate until the issue is resolved or the storage is provided. No amounts have been recognized in the financial statements as of September 30, 2012 for the second claim. The final outcome of this matter cannot be determined at this time.

Sufficient pool storage capacity for spent fuel is available at Plant Vogtle Units 1 and 2 to maintain full-core discharge capability for both units into 2014. Construction of an on-site dry storage facility at Plant Vogtle Units 1 and 2 has begun and is expected to be operational in sufficient time to maintain pool full-core discharge capability. At Plants Hatch and Farley, on-site dry spent fuel storage facilities are operational and can be expanded to accommodate spent fuel through the expected life of each plant.

FERC Matters

See Note 3 to the financial statements of Mississippi Power under "FERC Matters" in Item 8 of the Form 10-K for additional information regarding Mississippi Power's request for revised rates related to the wholesale Municipal and Rural Associations (MRA) cost-based electric tariff. See Note 3 to the financial statements of Southern Company and Mississippi Power under "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K for information regarding Mississippi Power's construction of the Kemper IGCC.

On January 20, 2012, Mississippi Power reached a settlement agreement with its wholesale customers, which was executed by all parties on March 9, 2012. The settlement agreement provides that base rates under the cost-based electric tariff will increase by approximately $22.6 million over a 12-month period with revised rates effective April 1, 2012. In 2012, the amount of base rate revenues to be received from the agreed upon increase will be approximately $17.0 million. On March 12, 2012, Mississippi Power filed an unopposed motion to place wholesale MRA interim rates into effect pending approval of the settlement agreement between the parties by the FERC. On March 28, 2012, the FERC approved the motion to place interim rates into effect beginning in May 2012. On September 27, 2012, Mississippi Power, with its wholesale customers, filed a final settlement agreement with the FERC. On November 5, 2012, the settlement judge certified the settlement agreement to the FERC with the recommendation that it be approved. A decision by the FERC is expected by the end of 2012. The ultimate outcome of this matter cannot be determined at this time.

Georgia Power

Rate Plans

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Rate Plans" and "Retail Regulatory Matters – Rate Plans," respectively, in Item 8 of the Form 10-K for additional information on Georgia Power's 2010 ARP.

In accordance with the terms of the 2010 ARP, on November 1, 2012, Georgia Power filed the following tariff adjustments with the Georgia PSC to become effective on January 1, 2013:

• Increase the DSM tariffs by approximately $16 million;

• Increase the traditional base tariffs by approximately $58 million to recover the revenue requirements for Plant McDonough-Atkinson Units 4, 5, and 6 for the period through December 31, 2013, which also reflects a separate settlement agreement associated with the June 30, 2011 quarterly construction monitoring report for Plant McDonough-Atkinson (see Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Other Construction" and "Construction – Other Construction," respectively, in Item 8 of the Form 10-K for additional information); and

• Increase the MFF tariff, consistent with the adjustments above, as well as those related to the IFR and NCCR tariff adjustments described under "Fuel Cost Recovery" and "Nuclear Construction," respectively, herein.

Fuel Cost Recovery

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Fuel Cost Recovery" and "Retail Regulatory Matters – Fuel Cost Recovery," respectively, in Item 8 of the Form 10-K for additional information.

On June 21, 2012, the Georgia PSC approved a 19% decrease in Georgia Power's fuel cost recovery rates, which reduced annual billings by $567 million effective June 1, 2012. The decrease in fuel costs resulted from lower natural gas prices as a result of increased natural gas supplies.

165

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

As of September 30, 2012, Georgia Power's fuel cost over recovery balance totaled $199 million. This balance is slightly below the $200 million required to automatically trigger the Georgia PSC's approved IFR adjustment mechanism. On November 1, 2012, Georgia Power filed a request with the Georgia PSC to reduce fuel cost recovery rates, effective January 1, 2013, using the IFR process. The requested reduction would reduce annual billings by approximately $122 million. In accordance with the IFR process, the Georgia PSC will have 30 days to consider Georgia Power's request. The ultimate outcome of this matter cannot be determined at this time.

The over recovered fuel costs at September 30, 2012 are included in current liabilities and other deferred credits and liabilities on Southern Company's and Georgia Power's Condensed Balance Sheets herein. At December 31, 2011, Georgia Power's under recovered fuel balance totaled $137 million and is included in current assets on Southern Company's and Georgia Power's Condensed Balance Sheets herein. Fuel cost recovery revenues as recorded on the financial statements are adjusted for differences in actual recoverable fuel costs and amounts billed in current regulated rates. Accordingly, any changes in the billing factor will not have a significant effect on Southern Company's or Georgia Power's revenues or net income, but will affect cash flow.

2011 Integrated Resource Plan Update

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – 2011 Integrated Resource Plan Update" and "Retail Regulatory Matters – 2011 Integrated Resource Plan Update," respectively, in Item 8 of the Form 10-K for additional information.

On March 20, 2012, the Georgia PSC approved Georgia Power's request to decertify and retire two coal-fired generation units at Plant Branch as of October 31, 2013 and December 31, 2013 and an oil-fired unit at Plant Mitchell as of March 26, 2012, which was included in Georgia Power's 2011 IRP Update. The Georgia PSC also approved three PPAs totaling 998 MWs with Southern Power for capacity and energy that will commence in 2015 and end in 2030. The PPAs remain subject to FERC approval. The ultimate outcome of this matter cannot be determined at this time.

Separately, on October 16, 2012, the Georgia PSC approved a 50 MW PPA with a Qualifying Facility for capacity and energy that will commence in 2015 and end in 2035. This PPA is expected to result in contractual obligations of approximately $13 million in 2015, $16 million in 2016, and $376 million in total thereafter.

Advanced Solar Initiative

Georgia Power filed a new solar initiative with the Georgia PSC on September 26, 2012. If approved, Georgia Power may acquire up to 210 MWs of additional solar capacity over a three-year period through long-term contracts. The ultimate outcome of this matter cannot be determined at this time.

Nuclear Construction

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Nuclear Construction" and "Construction – Nuclear," respectively, in Item 8 of the Form 10-K for additional information regarding Georgia Power's construction of Plant Vogtle Units 3 and 4.

On February 16, 2012, a group of petitioners who had intervened in the NRC's combined construction and operating licenses (COLs) proceedings for Plant Vogtle Units 3 and 4 filed a petition in the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review and a stay of the NRC's issuance of the COLs. In addition, on February 16, 2012, another group of petitioners filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review of the NRC's certification of the Westinghouse Design Control Document, as amended (DCD). On April 3, 2012, the U.S. Court of Appeals for the District of Columbia Circuit granted a motion filed by these two groups of petitioners to consolidate their challenges. On April 18, 2012, another group of petitioners filed a motion to stay the effectiveness of the order issuing the COLs for Plant Vogtle Units 3 and 4 with the U.S. District Court for the District of Columbia. On July 11, 2012, the U.S. Court of Appeals for the District of Columbia Circuit denied the petitioners' motion to stay the effectiveness of the COLs. Georgia Power has intervened in and intends to vigorously contest these petitions.

166

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4. In addition, the Georgia PSC voted to approve inclusion of the related CWIP accounts in rate base. Also in 2009, the Governor of the State of Georgia signed into law the Georgia Nuclear Energy Financing Act that allows Georgia Power to recover financing costs for nuclear construction projects by including the related CWIP accounts in rate base during the construction period. With respect to Plant Vogtle Units 3 and 4, this legislation allows Georgia Power to recover projected financing costs of approximately $1.7 billion during the construction period beginning in 2011, which reduces the projected in-service cost to approximately $4.4 billion. The Georgia PSC has ordered Georgia Power to report against this total certified cost of approximately $6.1 billion. On August 21, 2012, the Georgia PSC voted to approve Georgia Power's sixth semi-annual construction monitoring report including total costs of $2.0 billion for Plant Vogtle Units 3 and 4 incurred through December 31, 2011. Georgia Power will continue to file construction monitoring reports by February 28 and August 31 of each year during the construction period.

In addition, in December 2010, the Georgia PSC approved Georgia Power's NCCR tariff. The NCCR tariff became effective January 1, 2011 and adjustments are filed with the Georgia PSC on November 1 of each year to become effective on January 1 of the following year. On November 1, 2012, Georgia Power filed to increase the NCCR tariff by approximately $50 million effective January 1, 2013. Through the NCCR tariff, Georgia Power is collecting and amortizing to earnings approximately $91 million of financing costs, capitalized in 2009 and 2010, over the five-year period ending December 31, 2015, in addition to the ongoing financing costs. At September 30, 2012, approximately $59 million of these 2009 and 2010 costs remained in CWIP.

Georgia Power, Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and the City of Dalton, Georgia, an incorporated municipality in the State of Georgia acting by and through its Board of Water, Light, and Sinking Fund Commissioners (collectively, Owners) and Westinghouse and Stone & Webster, Inc. (collectively, Contractor) have established both informal and formal dispute resolution procedures in accordance with the engineering, procurement, and construction agreement for Plant Vogtle Units 3 and 4 (Vogtle 3 and 4 Agreement) in order to resolve issues arising during the course of constructing a project of this magnitude. The Contractor and Georgia Power (on behalf of the Owners) have successfully initiated both formal and informal claims through these procedures, including ongoing claims, to resolve disputes. When matters are not resolved through these procedures, the parties may proceed to litigation. The Contractor and the Owners are involved in litigation with respect to certain claims that have not been resolved through the formal dispute resolution process.

During the course of construction activities, issues have arisen that may impact the project budget and schedule. The most significant issues relate to costs associated with design changes to the DCD and costs associated with delays in the project schedule related to the timing of approval of the DCD and issuance of the COLs by the NRC. The Owners and the Contractor have begun negotiations regarding these issues, including the assertion by the Contractor that the Owners are responsible for these costs under the terms of the Vogtle 3 and 4 Agreement. Through correspondence sent to the Owners, the Contractor provided its proposed adjustment to the contract price and initiated the formal dispute resolution process. The Contractor's estimated adjustment attributable to Georgia Power (based on Georgia Power's ownership interest) is approximately $425 million (in 2008 dollars) with respect to these issues. Georgia Power has not agreed with the amount of these proposed adjustments or that the Owners have responsibility for any costs related to these issues. On November 1, 2012, Georgia Power and the other Owners filed suit against the Contractor in the U.S. District Court for the Southern District of Georgia, seeking a declaratory judgment that the Owners are not responsible for the costs related to these issues. Also on November 1, 2012, the Contractor filed suit against Georgia Power and the other Owners in the U.S. District Court for the District of Columbia, alleging the Owners are responsible for the costs related to these issues and seeking payment from the Owners of the full amount of these costs. While litigation has commenced, Georgia Power expects negotiations with the Contractor to continue with respect to cost and schedule during which time the parties will attempt to reach a mutually acceptable compromise of their positions. Georgia Power intends to vigorously defend its positions. If these costs ultimately are imposed upon the Owners, Georgia Power would seek

167

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

an amendment to the certified cost of Plant Vogtle Units 3 and 4, if necessary. In connection with these negotiations, the Owners are evaluating whether maintaining the currently scheduled commercial operation dates of 2016 and 2017 remains in the best interest of their customers. Additional claims by the Contractor or Georgia Power (on behalf of the Owners) are expected to arise throughout the construction of Plant Vogtle Units 3 and 4.

In addition, there are processes in place that are designed to assure compliance with the design requirements specified in the DCD and the COLs, including rigorous inspection by Southern Nuclear and the NRC that occurs throughout construction. During a routine inspection in April 2012, the NRC identified that certain details of the rebar construction in the Plant Vogtle Unit 3 nuclear island were not consistent with the DCD. In May 2012, Southern Nuclear received an official notice of violation relating to these findings from the NRC. The design changes were determined to have minimal safety significance and, on October 18, 2012, the NRC approved a license amendment request to clarify that the nuclear island concrete and rebar construction will conform to NRC requirements. Various inspection and other issues are expected to arise from time to time as construction proceeds,which may result in additional license amendments or require other resolution.

There are pending technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4, including legal challenges to the NRC issuance of the COLs and certification of the DCD. Similar additional challenges at the state and federal level are expected as construction proceeds.

The ultimate outcome of these matters cannot be determined at this time.

Other Construction

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Other Construction" and "Construction – Other Construction," respectively, in Item 8 of the Form 10-K for additional information.

Plant McDonough Unit 1 was retired on February 29, 2012. Georgia Power placed Plant McDonough-Atkinson Unit 5 into service on April 26, 2012 and Plant McDonough-Atkinson Unit 6 was placed into service on October 28, 2012.

Gulf Power

Retail Base Rate Case

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Retail Base Rate Case" in Item 8 of the Form 10-K for additional information.

On March 12, 2012, the Florida PSC approved a permanent increase in retail base rates and charges of $64 million effective April 11, 2012. The amount of the permanent increase includes the previously approved $38.5 million interim retail rate increase implemented in September 2011. The Florida PSC's decision on the amount of the permanent increase also included a determination that none of the base rate revenues collected on an interim basis would be refunded. Gulf Power's authorized retail ROE is a range of 9.25% to 11.25% with new retail base rates set at the midpoint retail ROE of 10.25%. In addition, the Florida PSC also approved a step increase to Gulf Power's retail base rates and charges of $4 million to be effective in January 2013.

Cost Recovery Clauses

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Cost Recovery Clauses" in Item 8 of the Form 10-K for additional information.

On November 5, 2012, the Florida PSC approved Gulf Power's annual rate clause requests for its fuel, purchased power capacity, conservation, and environmental compliance cost recovery factors for 2013. The net effect of the approved changes is a 1.9% rate increase for residential customers using 1,000 KWHs per month.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a flue gas desulfurization system (scrubber) on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court of Harrison County, Mississippi (Chancery Court). These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, excluding AFUDC, and it is scheduled for completion in December 2015. Gulf Power's portion of the cost is expected to be recovered through the environmental cost recovery clause. The ultimate outcome of this matter cannot be determined at this time.

Over recovered environmental costs at September 30, 2012 totaled $6.9 million compared to $10.0 million at December 31, 2011. These amounts are included in other regulatory liabilities, current on Gulf Power's Condensed Balance Sheets herein.

Energy Conservation Cost Recovery

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Energy Conservation Cost Recovery" in Item 8 of the Form 10-K for additional information.

Under recovered energy conservation costs at September 30, 2012 totaled $0.2 million compared to $3.1 million at December 31, 2011. These amounts are included in under recovered regulatory clause revenues on Gulf Power's Condensed Balance Sheets herein.

Performance Evaluation Plan

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Performance Evaluation Plan" in Item 8 of the Form 10-K for additional information regarding Mississippi Power's base rates.

On April 2, 2012, Mississippi Power filed a motion to suspend the 2011 PEP lookback filing. Unresolved matters related to certain costs included in the 2010 PEP lookback filing also impact the 2011 PEP lookback filing, making it impractical to determine Mississippi Power's actual retail return on investment for 2011 for purposes of the 2011 PEP lookback filing. An order granting the suspension of the 2011 PEP lookback was signed by the Mississippi PSC on May 8, 2012. While Mississippi Power does not expect the resolution of these unresolved matters to have a material impact on its financial statements, the ultimate outcome of these matters cannot be determined at this time.

System Restoration Rider

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – System Restoration Rider" in Item 8 of the Form 10-K for additional information.

On February 2, 2012, Mississippi Power submitted its 2012 System Restoration Rider (SRR) rate filing with the Mississippi PSC, which proposed that the 2012 SRR rate level remain at zero and Mississippi Power be allowed to accrue approximately $3.7 million to the property damage reserve in 2012. On April 3, 2012, the filing was approved by the Mississippi PSC.

Environmental Compliance Overview Plan

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Environmental Compliance Overview Plan" in Item 8 of the Form 10-K for information on Mississippi Power's annual environmental filing with the Mississippi PSC.

On February 14, 2012, Mississippi Power submitted its 2012 ECO Plan filing, which proposed a 0.3% increase in annual revenues for Mississippi Power. In compliance with the CPCN to construct a scrubber on Plant Daniel Units 1 and 2, Mississippi Power revised the 2012 ECO Plan filing to exclude scrubber expenditures from rate base, which resulted in a 0.16% decrease in annual revenues. On June 22, 2012, the 2012 ECO Plan filing, including the proposed rate decrease, was approved by the Mississippi PSC, effective on June 29, 2012.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a scrubber on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court. These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, with Mississippi Power's portion being $330 million, excluding AFUDC. The project is scheduled for completion in December 2015. Mississippi Power's portion of the cost is expected to be recovered through the ECO Plan. As of September 30, 2012, total project expenditures were $118.4 million, with Mississippi Power's portion being $59.2 million. The ultimate outcome of this matter cannot be determined at this time.

Certificated New Plant

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "Integrated Coal Gasification Combined Cycle" herein for additional information.

On May 23, 2012, the Mississippi Public Utilities Staff signed a joint stipulation with Mississippi Power to establish a new rate schedule for Certificated New Plant-A (CNP-A), a proposed cost recovery mechanism designed specifically to recover financing costs during the construction phase of the Kemper IGCC. An amended and restated stipulation was subsequently executed and filed on June 1, 2012. On June 14, 2012, Mississippi Power submitted to the Mississippi PSC a proposed supplemental compliance filing to establish the new CNP-A rate schedule and a stipulated rate increase based upon the revenue request of between $55.3 million and $58.6 million to recover financing costs over the remainder of 2012.

On June 22, 2012, the Mississippi PSC denied the proposed CNP-A rate schedule and the 2012 rate recovery filings submitted by Mississippi Power, pending a final ruling from the Mississippi Supreme Court regarding the motion for stay and notice of appeal filed by the Sierra Club on April 26, 2012 relating to the Mississippi PSC's issuance of the CPCN for the Kemper IGCC. On July 9, 2012, Mississippi Power appealed the Mississippi PSC's June 22, 2012 decision to the Mississippi Supreme Court and requested interim rates under bond of $55.3 million. On July 31, 2012, the Mississippi Supreme Court denied Mississippi Power's request for interim rates under bond while the Mississippi Supreme Court decides Mississippi Power's appeal of the Mississippi PSC's June 22, 2012 decision.

On September 13, 2012, the Mississippi PSC filed the record in the appeal of the Mississippi PSC's June 22, 2012 decision with the Mississippi Supreme Court. If the Mississippi Supreme Court does not render a decision within 180 days of the filing of the record, the rates proposed on June 14, 2012 will go into effect, subject to refund by Mississippi Power.

The ultimate outcome of this matter cannot be determined at this time.

Fuel Cost Recovery

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Fuel Cost Recovery" in Item 8 of the Form 10-K for information regarding Mississippi Power's fuel cost recovery.

At September 30, 2012, the amount of over recovered retail fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $52.8 million compared to $42.4 million at December 31, 2011. Mississippi Power also has wholesale MRA and Market Based (MB) fuel cost recovery factors. At September 30, 2012, the amount of over recovered wholesale MRA and MB fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $16.8 million and $2.1 million, respectively, compared to $14.3 million and $2.2 million, respectively, at December 31, 2011. In addition, at September 30, 2012, the amount of under recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $0.2 million. At December 31, 2011, the amount of over recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $1.7 million. Mississippi Power's operating revenues are adjusted for differences in actual recoverable fuel cost and amounts billed in accordance with the currently approved cost recovery rate. Accordingly, any changes in the billing factors will not have a significant effect on Mississippi Power's revenues or net income, but will affect annual cash flow.

Storm Damage Cost Recovery

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Storm Damage Cost Recovery" in Item 8 in the Form 10-K for information regarding Mississippi Power's storm damage cost recovery. In August 2012, Hurricane Isaac hit the Gulf Coast of the United States and caused damage within Mississippi Power's service area. The estimated total storm restoration costs relating to Hurricane Isaac through September 30, 2012 were $9.7 million. Mississippi Power maintains a reserve to cover the cost of damage from major storms to its transmission and distribution facilities and generally the cost of uninsured damage to its generation facilities and other property. At September 30, 2012, the balance in the storm reserve was $58.7 million.

Integrated Coal Gasification Combined Cycle

See Note 3 to the financial statements of Southern Company and Mississippi Power under "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K for information regarding Mississippi Power's construction of the Kemper IGCC.

In May 2010, Mississippi Power filed a motion with the Mississippi PSC accepting the conditions contained in the Mississippi PSC order confirming Mississippi Power's application for a CPCN authorizing the acquisition, construction, and operation of the Kemper IGCC. In June 2010, the Mississippi PSC issued the CPCN (2010 MPSC Order).

In June 2010, the Sierra Club filed an appeal of the Mississippi PSC's June 2010 decision to grant the CPCN for the Kemper IGCC with the Chancery Court. Subsequently, in July 2010, the Sierra Club also filed an appeal directly with the Mississippi Supreme Court. In October 2010, the Mississippi Supreme Court dismissed the Sierra Club's direct appeal. In February 2011, the Chancery Court issued a judgment affirming the 2010 MPSC Order and, in March 2011, the Sierra Club appealed the Chancery Court's decision to the Mississippi Supreme Court. On March 15, 2012, the Mississippi Supreme Court reversed the Chancery Court's decision and the 2010 MPSC Order and remanded the matter to the Mississippi PSC to correct the 2010 MPSC Order. The Mississippi Supreme Court concluded that the 2010 MPSC Order did not cite in sufficient detail substantial evidence upon which the Mississippi Supreme Court could determine the basis for the findings of the Mississippi PSC granting the CPCN.

On March 30, 2012, the Mississippi PSC issued temporary authorization for the continuation of construction of the Kemper IGCC. On April 24, 2012, the Mississippi PSC issued a detailed order on remand (2012 MPSC Order) confirming the CPCN for the Kemper IGCC subject to the same conditions set forth in the 2010 MPSC Order. On April 26, 2012, the Sierra Club filed a motion for stay and a notice of appeal of the 2012 MPSC Order with the Chancery Court. On May 18, 2012, Mississippi Power's motion to join the appeal was approved. On August 7, 2012, the Sierra Club withdrew its motion for stay.

The certificated cost estimate of the Kemper IGCC is $2.4 billion, net of $245.3 million of grants awarded to the project by the DOE under the Clean Coal Power Initiative Round 2 (CCPI2) and excluding the cost of the lignite mine and equipment and the carbon dioxide (CO₂) pipeline facilities. The 2012 MPSC Order, like the 2010 MPSC Order, (1) approved a construction cost cap of up to $2.88 billion (exemptions from the cost cap include the cost of the lignite mine and equipment, the CO₂ pipeline facilities, AFUDC, and certain general exceptions, including change of law, force majeure, and beneficial capital, which exists when Mississippi Power demonstrates that the purpose and effect of the construction cost increase is to produce efficiencies that will result in a neutral or favorable effect on the ratepayers, relative to the original proposal), (2) provided for the establishment of operational cost and revenue parameters based upon assumptions in Mississippi Power's proposal, and (3) approved financing cost recovery on CWIP balances not to exceed the certificated cost estimate, which provided for the accrual of AFUDC in 2010 and 2011 and provides for the current recovery of financing costs on 100% of CWIP in 2012, 2013, and through May 1, 2014 (provided that the amount of CWIP allowed is (i) reduced by the amount of state and federal government construction cost incentives received by Mississippi Power in excess of $296 million to the extent that such amount increases cash flow for the pertinent regulatory period and (ii) justified by a showing that such CWIP allowance will benefit customers over the life of the Kemper IGCC).

172

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

Mississippi Power's current cost estimate for the Kemper IGCC equals the $2.88 billion cost cap, including a $40 million to $50 million contingency. The Mississippi PSC and the Mississippi Public Utilities Staff have engaged their independent monitors to assess the current cost estimates and schedule projections for the Kemper IGCC. These consultants are issuing reports with their own opinions as to the likelihood that costs for the Kemper IGCC will remain under the $2.88 billion cost cap and as to the expected in-service date. While Mississippi Power continues to believe its cost estimate and schedule projection remain appropriate based on the current status of the project, it is possible that Mississippi Power will experience further cost increases and/or schedule delays with respect to the Kemper IGCC. Certain factors have caused and may continue to cause the costs for the Kemper IGCC to increase and/or schedule delays to occur including, but not limited to, costs and productivity of labor, adverse weather conditions, shortages and inconsistent quality of equipment, materials and labor, contractor or supplier delay or non-performance under construction or other agreements, and unforeseen engineering problems. To the extent that costs beyond any permitted exceptions to the cost cap exceed $2.88 billion or the Mississippi PSC disallows a portion of the costs relating to the Kemper IGCC, including financing costs, charges to expense may occur and these charges could be material.

The Kemper IGCC, expected to be in service in May 2014, will use locally mined lignite (an abundant, lower heating value coal) from a mine adjacent to the Kemper IGCC as fuel. The mine is scheduled to be placed into service in June 2013. In conjunction with the Kemper IGCC, Mississippi Power will own the lignite mine and equipment and has acquired and will continue to acquire mineral reserves located around the Kemper IGCC site in Kemper County. The estimated capital cost of the mine is approximately $245 million, of which $127 million has been incurred through September 30, 2012.

In May 2010, Mississippi Power executed a 40-year management fee contract with Liberty Fuels Company, LLC, a wholly-owned subsidiary of The North American Coal Corporation (Liberty Fuels), which will develop, construct, and manage the mining operations. Because Liberty Fuels conducts all of its activities on behalf of Mississippi Power, Liberty Fuels qualifies as a variable interest entity for which Mississippi Power is the primary beneficiary. The contract with Liberty Fuels is effective through the end of the mine reclamation. As the mining permit holder, Liberty Fuels has a legal obligation to perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities. Consistent with the requirements of consolidation accounting, Liberty Fuels is consolidated in the financial statements of Mississippi Power and accordingly the asset retirement cost and the ARO have been recorded in Mississippi Power's financial statements. In addition to the obligation to fund the reclamation activities, Mississippi Power currently provides working capital support to Liberty Fuels through cash advances for capital purchases, payroll, and other operating expenses.

In December 2011, the Mississippi Department of Environmental Quality (MDEQ) approved the surface coal mining and the water pollution control permits for the mining operations operated by Liberty Fuels. On January 12, 2012, two individuals each filed a notice of appeal and a request for evidentiary hearing with the MDEQ regarding the surface coal mining and water pollution control permits. On March 8, 2012, the MDEQ permit board affirmed its issuance of the surface coal mining and water pollution control permits.

In 2009, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $133 million of Internal Revenue Code Section 48A tax credits (Phase I) to Mississippi Power. In April 2011, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $279 million of Internal Revenue Code Section 48A tax credits (Phase II) to Mississippi Power. The utilization of Phase I and Phase II credits is dependent upon meeting the IRS certification requirements, including an in-service date no later than May 11, 2014 for the Phase I credits and April 19, 2016 for the Phase II credits. In order to remain eligible for the Phase II credits, Mississippi Power plans to capture and sequester (via enhanced oil recovery) at least 65% of the CO₂ produced by the Kemper IGCC during operations in accordance with the rules for Section 48A investment tax credits. Through September 30, 2012, Mississippi Power received or accrued tax benefits totaling $276.8 million for these tax credits, which will be amortized as a reduction to depreciation and amortization over the life of the Kemper IGCC. On October 15, 2012, Mississippi Power filed an application with the DOE for certification of the Kemper IGCC for additional tax credits under the Internal Revenue Code Section 48A (Phase III). A portion of the tax credits realized by Mississippi Power may be subject to recapture upon successful completion of SMEPA's

purchase of undivided interest in the Kemper IGCC. Based on current tax laws and regulations in effect, Mississippi Power expects to receive substantially all of the tax credits accrued through September 30, 2012 by September 30, 2013.

In July 2010, Mississippi Power and SMEPA entered into an asset purchase agreement whereby SMEPA agreed to purchase a 17.5% undivided interest in the Kemper IGCC. In December 2010, Mississippi Power and SMEPA filed a joint petition with the Mississippi PSC requesting regulatory approval of SMEPA's 17.5% undivided interest in the Kemper IGCC. On February 28, 2012, the Mississippi PSC approved the joint petition for the sale and transfer of 17.5% of the Kemper IGCC to SMEPA. On June 29, 2012, Mississippi Power and SMEPA signed an amendment to the asset purchase agreement whereby SMEPA extended its option to purchase until December 31, 2012 and reduced its purchase commitment percentage from a 17.5% to a 15% undivided interest in the Kemper IGCC, subject to approval by the Mississippi PSC. The closing of this transaction is conditioned upon execution of a joint ownership and operating agreement, receipt of all construction permits, appropriate regulatory approvals, financing, and other conditions. On September 27, 2012, SMEPA received a conditional loan commitment from Rural Utilities Service to provide funding for SMEPA's undivided interest in the Kemper IGCC.

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the purchase. While the expectation is that the amount will be applied to the purchase price at closing, Mississippi Power would be required to refund the deposit upon the termination of the asset purchase agreement, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies. Given the interest-bearing nature of the deposit and SMEPA's ability to request a refund, the deposit has been presented as a current liability in Mississippi Power's Condensed Balance Sheet herein and as financing proceeds in Mississippi Power's Condensed Statement of Cash Flows herein.

As of September 30, 2012, Mississippi Power had spent a total of $2.1 billion on the Kemper IGCC including the cost of the lignite mine and equipment, the CO₂ pipeline facilities, and regulatory filing costs. Of this total, $2.0 billion was included in CWIP (which is net of $245.3 million of CCPI2 grant funds), $30.2 million was recorded in other regulatory assets, $3.0 million was recorded in other deferred charges and assets, and $1.0 million was previously expensed.

The Mississippi PSC order established periodic prudence reviews during the annual CWIP review process. Of the total costs of $51 million incurred through March 2009, $46 million has been reviewed and deemed prudent by the Mississippi PSC in the 2010 MPSC Order and again in the 2012 MPSC Order. A decision regarding the remaining $5 million has not been issued. The timing of the review of the remaining Kemper IGCC costs has not been determined.

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "Retail Regulatory Matters – Certificated New Plant" herein for information on the proposed rate schedules related to the Kemper IGCC.

The ultimate outcome of these matters cannot be determined at this time.

Valuation Methodologies

The energy-related derivatives primarily consist of over-the-counter financial products for natural gas and physical power products including, from time to time, basis swaps. These are standard products used within the energy industry and are valued using the market approach. The inputs used are mainly from observable market sources, such as forward natural gas prices, power prices, implied volatility, and LIBOR interest rates. Interest rate and foreign currency derivatives are also standard over-the-counter financial products valued using the market approach. Inputs for interest rate derivatives include LIBOR interest rates, interest rate futures contracts, and occasionally implied volatility of interest rate options. Inputs for foreign currency derivatives are from observable market sources. See Note (H) herein for additional information on how these derivatives are used.

"Other investments" include investments in funds that are valued using the market approach and income approach. Securities that are traded in the open market are valued at the closing price on their principal exchange as of the measurement date. Discounts are applied in accordance with GAAP when certain trading restrictions exist. For investments that are not traded in the open market, the price paid will have been determined based on market factors including comparable multiples and the expectations regarding cash flows and business plan execution. As the investments mature or if market conditions change materially, further analysis of the fair market value of the investment is performed. This analysis is typically based on a metric, such as multiple of earnings, revenues, earnings before interest and income taxes, or earnings adjusted for certain cash changes. These multiples are based on comparable multiples for publicly traded companies or other relevant prior transactions.

For fair value measurements of investments within the nuclear decommissioning trusts and rabbi trust funds, specifically the fixed income assets using significant other observable inputs and unobservable inputs, the primary valuation technique used is the market approach. External pricing vendors are designated for each of the asset classes in the nuclear decommissioning trusts and rabbi trust funds with each security discriminately assigned a primary pricing source, based on similar characteristics.

A market price secured from the primary source vendor is then evaluated by management in its valuation of the assets within the trusts. As a general approach, market pricing vendors gather market data (including indices and market research reports) and integrate relative credit information, observed market movements, and sector news into proprietary pricing models, pricing systems, and mathematical tools. Dealer quotes and other market information including live trading levels and pricing analysts' judgment are also obtained when available.

The NRC requires licensees of commissioned nuclear power reactors to establish a plan for providing reasonable assurance of funds for future decommissioning. Alabama Power and Georgia Power have external trust funds (the Funds) to comply with the NRC's regulations. The commingled funds in the nuclear decommissioning trusts are invested primarily in a diversified portfolio of high grade money market instruments, including, but not limited to, commercial paper, notes, repurchase agreements, and other evidences of indebtedness with a maturity not exceeding 13 months from the date of purchase. The commingled funds will, however, maintain a dollar-weighted average portfolio maturity of 90 days or less. The assets may be longer term investment grade fixed income obligations having a maximum five-year final maturity with put features or floating rates with a reset date of 13 months or less. The primary objective for the commingled funds is a high level of current income consistent with stability of principal and liquidity. The corporate bonds - commingled funds represent the investment of cash collateral received under the Funds' managers' securities lending program that can only be sold upon the return of the loaned securities. See Note 1 to the financial statements of Southern Company and Georgia Power under "Nuclear Decommissioning" in Item 8 of the Form 10-K for additional information.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

Alabama Power's nuclear decommissioning trust includes investments in Trust-Owned Life Insurance (TOLI). The taxable nuclear decommissioning trust invests in the TOLI in order to minimize the impact of taxes on the portfolio and can draw on the value of the TOLI through death proceeds, loans against the cash surrender value, and/or the cash surrender value, subject to legal restrictions. The amounts reported in the table above reflect the fair value of investments the insurer has made in relation to the TOLI agreements. The nuclear decommissioning trust does not own the underlying investments, but the fair value of the investments approximates the cash surrender value of the TOLI policies. The investments made by the insurer are in commingled funds. The commingled funds primarily include investments in domestic and international equity securities and predominantly high-quality fixed income securities. These fixed income securities may include U.S. Treasury and government agency fixed income securities, non-U.S. government and agency fixed income securities, domestic and foreign corporate fixed income securities, and, to some degree, mortgage and asset backed securities.

(D) STOCKHOLDERS' EQUITY

Earnings per Share

For Southern Company, the only difference in computing basic and diluted earnings per share is attributable to awards outstanding under the stock option and performance share plans. See Note 8 to the financial statements of Southern Company in Item 8 of the Form 10-K for information on the stock option and performance share plans. The effects of both stock options and performance share award units were determined using the treasury stock method. Shares used to compute diluted earnings per share were as follows:

	Three Months Ended September 30, 2012	Three Months Ended September 30, 2011	Nine Months Ended September 30, 2012	Nine Months Ended September 30, 2011

(G) EFFECTIVE TAX RATE AND UNRECOGNIZED TAX BENEFITS

Effective Tax Rate

See Note 5 to the financial statements of each registrant in Item 8 of the Form 10-K for information on the effective income tax rate.

Southern Company

Southern Company's effective tax rate is typically lower than the statutory rate due to its employee stock plans' dividend deduction and non-taxable AFUDC equity.

Southern Company's effective tax rate was 35.3% for the nine months ended September 30, 2012 compared to 36.1% for the corresponding period in 2011. The decrease was primarily related to state income tax credits. See "Unrecognized Tax Benefits" herein for additional information.

Alabama Power

Alabama Power's effective tax rate was 38.8% for the nine months ended September 30, 2012 compared to 39.0% for the corresponding period in 2011. The decrease was primarily due to a decrease in Alabama state income taxes as a result of an increase in the state income tax deduction for federal income taxes paid.

183

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

Georgia Power

Georgia Power's effective tax rate was 35.8% for the nine months ended September 30, 2012 and for the corresponding period in 2011.

Gulf Power

Gulf Power's effective tax rate was 37.3% for the nine months ended September 30, 2012 compared to 36.6% for the corresponding period in 2011. The increase was primarily due to a decrease in non-taxable AFUDC equity.

Mississippi Power

Mississippi Power's effective tax rate was 26.7% for the nine months ended September 30, 2012 compared to 32.6% for the corresponding period in 2011. The decrease was primarily due to an increase in non-taxable AFUDC equity related to the Kemper IGCC construction.

Southern Power

Southern Power's effective tax rate was 34.4% for the nine months ended September 30, 2012 compared to 35.9% for the corresponding period in 2011. The decrease was primarily due to an increase in convertible investment tax credits and state tax credits.

Unrecognized Tax Benefits

Changes during 2012 for unrecognized tax benefits were as follows:

	Southern Company			Alabama Power			Georgia Power			Gulf Power			Mississippi Power		Southern Power
	(in millions)
Unrecognized tax benefits as of December 31, 2011	$	120		$	32		$	47		$	3		$	5	$	3
Tax positions from current periods	7			3			2			—			—		1
Tax positions from prior periods	(21		)	(4		)	(18		)	1			—		(2		)
Reductions due to settlements	(5		)	(2		)	(3		)	(1		)	—		1
Reductions due to expired statute of limitations	(3		)	—			(3		)	—			—		—
Balance as of September 30, 2012	$	98		$	29		$	25		$	3		$	5	$	3

The tax positions from current periods relate primarily to the tax accounting method change for repairs-generation assets. See "Tax Method of Accounting for Repairs" herein for additional information. The decreases in tax positions from prior periods primarily relate to state income tax credits. The reductions due to settlements relate to a settlement with the IRS of the calculation methodology for the production activities deduction.

184

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

The impact on the effective tax rate, if recognized, was as follows:

	As of September 30, 2012			As of December 31, 2011
		Southern Company
	(in millions)
Tax positions impacting the effective tax rate		$	38	$	69
Tax positions not impacting the effective tax rate		60		51
Balance of unrecognized tax benefits		$	98	$	120

The tax positions impacting the effective tax rate primarily relate to state income tax credits and a litigation settlement refund claim for Southern Company. See Note 5 to the financial statements of Southern Company under "Effective Tax Rate" in Item 8 of the Form 10-K for additional information. The tax positions not impacting the effective tax rate relate to the timing difference associated with the tax accounting method change for repairs-generation assets. See "Tax Method of Accounting for Repairs" herein for additional information. These amounts are presented on a gross basis without considering the related federal or state income tax impact.

Accrued interest for unrecognized tax benefits was as follows:

		Southern Company
	(in millions)
Interest accrued as of December 31, 2011		$	10
Interest reclassified due to settlements		(9		)
Interest accrued during the period		—
Balance as of September 30, 2012		$	1

All of the registrants classify interest on tax uncertainties as interest expense. The interest reclassified due to settlements is primarily associated with state income tax credits and a settlement with the IRS related to the calculation methodology for the production activities deduction.

None of the registrants accrued any penalties on uncertain tax positions.

It is reasonably possible that the amount of the unrecognized tax benefits associated with a majority of the registrants' unrecognized tax positions will significantly increase or decrease within the next 12 months. The resolution of the tax accounting method change for repairs-generation assets, as well as the conclusion or settlement of federal and state audits, could also impact the balances significantly. At this time, an estimate of the range of reasonably possible outcomes cannot be determined.

Tax Method of Accounting for Repairs

Southern Company submitted a tax accounting method change for repair costs associated with its subsidiaries' generation, transmission, and distribution systems with the filing of the 2009 federal income tax return in September 2010. In August 2011, the IRS issued a revenue procedure, which provides a safe harbor method of accounting that taxpayers may use to determine repair costs for transmission and distribution property. However, the IRS continues to work with the utility industry in an effort to resolve the repair costs for generation assets matter in a consistent manner for all utilities. In December 2011, the IRS published regulations on the deduction and capitalization of expenditures related to tangible property that generally apply for tax years beginning on or after January 1, 2012. The utility industry anticipates more detailed guidance concerning these regulations. Due to uncertainty regarding the ultimate resolution of the repair costs for generation assets, an unrecognized tax position has been recorded for the tax accounting method change for repairs-generation assets. The ultimate outcome of this matter cannot be determined at this time.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

(H) DERIVATIVES

Southern Company, the traditional operating companies, and Southern Power are exposed to market risks, primarily commodity price risk, interest rate risk, and occasionally foreign currency risk. To manage the volatility attributable to these exposures, each company nets its exposures, where possible, to take advantage of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to each company's policies in areas such as counterparty exposure and risk management practices. Each company's policy is that derivatives are to be used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress testing, and sensitivity analysis. Derivative instruments are recognized at fair value in the balance sheets as either assets or liabilities and are presented on a gross basis.

Energy-Related Derivatives

The traditional operating companies and Southern Power enter into energy-related derivatives to hedge exposures to electricity, gas, and other fuel price changes. However, due to cost-based rate regulations and other various cost recovery mechanisms, the traditional operating companies have limited exposure to market volatility in commodity fuel prices and prices of electricity. Each of the traditional operating companies manages fuel-hedging programs, implemented per the guidelines of their respective state PSCs, through the use of financial derivative contracts, which is expected to continue to mitigate price volatility. Southern Power has limited exposure to market volatility in commodity fuel prices and prices of electricity because its long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, Southern Power has been and may continue to be exposed to market volatility in energy-related commodity prices as a result of sales of uncontracted generating capacity.

To mitigate residual risks relative to movements in electricity prices, the traditional operating companies and Southern Power may enter into physical fixed-price or heat rate contracts for the purchase and sale of electricity through the wholesale electricity market. To mitigate residual risks relative to movements in gas prices, the traditional operating companies and Southern Power may enter into fixed-price contracts for natural gas purchases; however, a significant portion of contracts are priced at market.

Energy-related derivative contracts are accounted for under one of three methods:

• Regulatory Hedges — Energy-related derivative contracts which are designated as regulatory hedges relate primarily to the traditional operating companies' fuel hedging programs, where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as the underlying fuel is used in operations and ultimately recovered through the respective fuel cost recovery clauses.

• Cash Flow Hedges — Gains and losses on energy-related derivatives designated as cash flow hedges, which are mainly used to hedge anticipated purchases and sales and are initially deferred in OCI before being recognized in the statements of income in the same period as the hedged transactions, are reflected in earnings.

• Not Designated — Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

Some energy-related derivative contracts require physical delivery as opposed to financial settlement, and this type of derivative is both common and prevalent within the electric industry. When an energy-related derivative contract is settled physically, any cumulative unrealized gain or loss is reversed and the contract price is recognized in the respective line item representing the actual price of the underlying goods being delivered.

186

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

At September 30, 2012, the net volume of energy-related derivative contracts for natural gas positions for the Southern Company system, together with the longest hedge date over which the respective entity is hedging its exposure to the variability in future cash flows for forecasted transactions and the longest date for derivatives not designated as hedges, were as follows:

	Net Purchased mmBtu	Longest Hedge Date	Longest Non-Hedge Date
	(in millions)
Southern Company	270	2017	2017
Alabama Power	55	2017	—
Georgia Power	107	2017	—
Gulf Power	63	2017	—
Mississippi Power	36	2017	—
Southern Power	9	2012	2017

In addition to the volumes discussed in the above table, the traditional operating companies and Southern Power enter into physical natural gas supply contracts that provide the option to sell back excess gas due to operational constraints. The maximum expected volume of natural gas subject to such a feature is 7 million mmBtu for Southern Company, 1 million mmBtu for Alabama Power, 3 million mmBtu for Georgia Power, 1 million mmBtu for Gulf Power, 1 million mmBtu for Mississippi Power, and 1 million mmBtu for Southern Power.

For cash flow hedges, the amounts expected to be reclassified from OCI to revenue and fuel expense for the next 12-month period ending September 30, 2013 are immaterial for all registrants.

Interest Rate Derivatives

Southern Company and certain subsidiaries also enter into interest rate derivatives to hedge exposure to changes in interest rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness. Derivatives related to existing variable rate securities or forecasted transactions are accounted for as cash flow hedges where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings, with any ineffectiveness recorded directly to earnings. Derivatives related to existing fixed rate securities are accounted for as fair value hedges, where the derivatives' fair value gains or losses and hedged items' fair value gains or losses are both recorded directly to earnings, providing an offset with any difference representing ineffectiveness.

At September 30, 2012, the following interest rate derivatives were outstanding:

	Notional Amount		Interest Rate Received		Interest Rate Paid			Hedge Maturity Date	Fair Value Gain (Loss) September 30, 2012

Foreign Currency Derivatives

Southern Company and certain subsidiaries may enter into foreign currency derivatives to hedge exposure to changes in foreign currency exchange rates arising from purchases of equipment denominated in a currency other than U.S. dollars. Derivatives related to a firm commitment in a foreign currency transaction are accounted for as fair value hedges where the derivatives' fair value gains or losses and the hedged items' fair value gains or losses are both recorded directly to earnings. Derivatives related to a forecasted transaction are accounted for as a cash flow hedge where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings. Any ineffectiveness is typically recorded directly to earnings; however, Mississippi Power has regulatory approval allowing it to defer any ineffectiveness associated with firm commitments related to the Kemper IGCC to a regulatory asset. The derivatives employed as hedging instruments are structured to minimize ineffectiveness.

At September 30, 2012, the following foreign currency derivatives were outstanding:

	Notional Amount	Forward Rate		Hedge Maturity Date	Fair Value Gain (Loss) September 30, 2012(c)

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

For the three and nine months ended September 30, 2012, the pre-tax effects of foreign currency derivatives designated as fair value hedging instruments on Southern Company's and Mississippi Power's statements of income were immaterial. For the three and nine months ended September 30, 2011, the pre-tax losses of foreign currency derivatives designated as fair value hedging instruments on Southern Company's and Mississippi Power's statements of income were $(3) million and $(2) million, respectively. The pre-tax effects of foreign currency derivatives designated as fair value hedging instruments on both Southern Company's and Mississippi Power's statements of income were offset with changes in the fair value of the purchase commitment related to equipment purchases; therefore, there was no impact on Southern Company's or Mississippi Power's statements of income.

For the three months ended September 30, 2012 and 2011, the pre-tax effects of interest rate derivatives designated as cash flow hedging instruments on the statements of income were as follows:

NOTES TO THE CONDENSED FINANCIAL STATEMENTS: (Continued)

For the three and nine months ended September 30, 2012 and 2011, the pre-tax effects of energy-related derivatives designated as cash flow hedging instruments on the statements of income were immaterial for all registrants.

There was no material ineffectiveness recorded in earnings for any registrant for any period presented.

For Southern Power's energy-related derivatives not designated as hedging instruments, a substantial portion of the pre-tax realized and unrealized gains and losses is associated with hedging fuel price risk of certain PPA customers and has no impact on net income or on fuel expense as presented in Southern Company's and Southern Power's statements of income. As a result, for the three and nine months ended September 30, 2012 and 2011, the pre-tax effects of energy-related derivatives not designated as hedging instruments on Southern Company's and Southern Power's statements of income were immaterial.

For the three and nine months ended September 30, 2012, the pre-tax effects of foreign currency derivatives not designated as hedging instruments were recorded as regulatory assets and liabilities and were immaterial for Southern Company and Mississippi Power.

Contingent Features

The registrants do not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain derivatives that could require collateral, but not accelerated payment, in the event of various credit rating changes of certain Southern Company subsidiaries. At September 30, 2012, the fair value of derivative liabilities with contingent features, by registrant, was as follows:

	Southern Company		Alabama Power		Georgia Power		Gulf Power		Mississippi Power		Southern Power
					(in millions)
Derivative liabilities	$	10	$	2	$	4	$	2	$	2	$	—

At September 30, 2012, the registrants had no collateral posted with their derivative counterparties. If collateral is required, fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral are not offset against fair value amounts recognized for derivatives executed with the same counterparty under the same master netting arrangement. The maximum potential collateral requirements arising from the credit-risk-related contingent features, at a rating below BBB- and/or Baa3, is $10 million for each registrant. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. For the traditional operating companies and Southern Power, included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade.

Southern Company, the traditional operating companies, and Southern Power are exposed to losses related to financial instruments in the event of counterparties' nonperformance. Southern Company, the traditional operating companies, and Southern Power only enter into agreements and material transactions with counterparties that have investment grade credit ratings by Moody's and S&P or with counterparties who have posted collateral to cover potential credit exposure. Southern Company, the traditional operating companies, and Southern Power have also established risk management policies and controls to determine and monitor the creditworthiness of counterparties in order to mitigate Southern Company's, the traditional operating companies', and Southern Power's exposure to counterparty credit risk. Therefore, Southern Company, the traditional operating companies, and Southern Power do not anticipate a material adverse effect on the financial statements as a result of counterparty nonperformance.

(I) ACQUISITIONS

Apex Nevada Solar, LLC Acquisition

On June 29, 2012, Southern Power and Turner Renewable Energy, Inc. (TRE), through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Apex Nevada Solar, LLC (Apex) from Sun Edison, LLC, the original developer of the project. Apex constructed and owns a 20-MW solar photovoltaic facility in North Las Vegas, Nevada. The solar facility began commercial operation on July 21, 2012. The output of the plant is contracted under a 25-year PPA with Nevada Power Company, a subsidiary of NV Energy, Inc., that began in July 2012. This PPA is being accounted for as an operating lease. The acquisition is in accordance with Southern Power's overall growth strategy.

Southern Power's acquisition of Apex included cash consideration of $102 million, of which $86.5 million was paid at closing and an additional $9.5 million was paid on September 28, 2012 upon completion of a project milestone. The remaining $6 million is expected to be paid in November 2012 upon achievement of the final milestone. As of September 30, 2012, the allocation of the purchase price to individual assets has not been finalized. As of the acquisition date, the entire purchase price was recorded as CWIP. Revenues and earnings with respect to Apex for the period ended September 30, 2012 were immaterial.

Spectrum Nevada Solar, LLC Acquisition

On September 28, 2012, Southern Power and TRE, through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Spectrum Nevada Solar, LLC (Spectrum) from Sun Edison, LLC, the original developer of the project.

Southern Power's acquisition of Spectrum consisted of cash consideration of $17.6 million paid at closing. An additional $99.9 million will be paid to a subsidiary of Sun Edison, LLC to complete the construction of the solar facility. Due to the proximity of the closing date to September 30, 2012, there has not been sufficient time to complete the final allocation of the purchase price to individual assets. As of September 30, 2012, the $17.6 million purchase price was reflected in CWIP on Southern Power's Condensed Balance Sheet herein.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

INTRODUCTION

INTRODUCTION

The condensed quarterly financial statements of each registrant included herein have been prepared by such registrant, without audit, pursuant to the rules and regulations of the SEC. The Condensed Balance Sheets as of December 31, 2011 have been derived from the audited financial statements of each registrant. In the opinion of each registrant's management, the information regarding such registrant furnished herein reflects all adjustments, which, except as otherwise disclosed, are of a normal recurring nature, necessary to present fairly the results of operations for the periods ended September 30, 2012 and 2011. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although each registrant believes that the disclosures regarding such registrant are adequate to make the information presented not misleading. Disclosures which would substantially duplicate the disclosures in the Form 10-K and details which have not changed significantly in amount or composition since the filing of the Form 10-K are generally omitted from this Quarterly Report on Form 10-Q. Therefore, these Condensed Financial Statements should be read in conjunction with the financial statements and the notes thereto included in the Form 10-K. Due to the seasonal variations in the demand for energy, operating results for the periods presented are not necessarily indicative of the operating results to be expected for the full year.

Certain prior year data presented in the financial statements have been reclassified to conform to the current year presentation.

Investments in Leveraged Leases

See Note 1 to the financial statements of Southern Company under "Leveraged Leases" in Item 8 of the Form 10-K for additional information.

The recent financial and operational performance of one of Southern Company's lessees and the associated generation assets has raised potential concerns on the part of Southern Company as to the credit quality of the lessee and the residual value of the assets. Current projections indicate significant uncertainty as to whether the lessee will be able to pay the December 2012 semi-annual rent payment in full. Southern Company continues to be engaged in discussions with the lessee and the holders of the project's nonrecourse debt to restructure the debt payments and the related rental payments to allow additional capital investment in the project to be made to improve the operation of the generation assets and the financial viability of the lease transaction. Southern Company continues to believe there is a reasonable possibility that it will be able to reach an agreement with the lessee and the debtholders to restructure the project prior to the end of 2012. However, due to continued poor performance of the generation assets and the uncertainties surrounding the receipt of the December 2012 semi-annual rent payment and its ability to successfully restructure the project, Southern Company has placed the lease on nonaccrual status whereby, effective July 2012, income associated with this investment is not recognized in the financial statements. If the attempts at restructuring the project are unsuccessful and the project is ultimately abandoned, the potential impairment loss that would be incurred is approximately $90 million on an after-tax basis. If the restructuring is successfully completed prior to the end of 2012, Southern Company will be required to record a reduction in leveraged lease income of up to approximately $20 million in the fourth quarter 2012. The ultimate outcome of this matter cannot be determined at this time.

(TRE), through a jointly-owned subsidiary owned 90% by Southern Power, acquired all of the outstanding membership interests of Apex Nevada Solar, LLC (Apex) from Sun Edison, LLC, the original developer of the project. Apex constructed and owns a 20-MW solar photovoltaic facility in North Las Vegas, Nevada. The solar facility began commercial operation on July 21, 2012. The output of the plant is contracted under a 25-year PPA with Nevada Power Company, a subsidiary of NV Energy, Inc., that began in July 2012. This PPA is being accounted for as an operating lease. The acquisition is in accordance with Southern Power's overall growth strategy.

Southern Power's acquisition of Apex included cash consideration of $102 million, of which $86.5 million was paid at closing and an additional $9.5 million was paid on September 28, 2012 upon completion of a project milestone. The remaining $6 million is expected to be paid in November 2012 upon achievement of the final milestone. As of September 30, 2012, the allocation of the purchase price to individual assets has not been finalized. As of the acquisition date, the entire purchase price was recorded as CWIP.

STOCKHOLDER'S EQUITY

STOCKHOLDERS' EQUITY

Earnings per Share

For Southern Company, the only difference in computing basic and diluted earnings per share is attributable to awards outstanding under the stock option and performance share plans. See Note 8 to the financial statements of Southern Company in Item 8 of the Form 10-K for information on the stock option and performance share plans. The effects of both stock options and performance share award units were determined using the treasury stock method. Shares used to compute diluted earnings per share were as follows:

	Three Months Ended September 30, 2012	Three Months Ended September 30, 2011	Nine Months Ended September 30, 2012	Nine Months Ended September 30, 2011

Valuation Methodologies

The energy-related derivatives primarily consist of over-the-counter financial products for natural gas and physical power products including, from time to time, basis swaps. These are standard products used within the energy industry and are valued using the market approach. The inputs used are mainly from observable market sources, such as forward natural gas prices, power prices, implied volatility, and LIBOR interest rates. Interest rate and foreign currency derivatives are also standard over-the-counter financial products valued using the market approach. Inputs for interest rate derivatives include LIBOR interest rates, interest rate futures contracts, and occasionally implied volatility of interest rate options. Inputs for foreign currency derivatives are from observable market sources. See Note (H) herein for additional information on how these derivatives are used.

"Other investments" include investments in funds that are valued using the market approach and income approach. Securities that are traded in the open market are valued at the closing price on their principal exchange as of the measurement date. Discounts are applied in accordance with GAAP when certain trading restrictions exist. For investments that are not traded in the open market, the price paid will have been determined based on market factors including comparable multiples and the expectations regarding cash flows and business plan execution. As the investments mature or if market conditions change materially, further analysis of the fair market value of the investment is performed. This analysis is typically based on a metric, such as multiple of earnings, revenues, earnings before interest and income taxes, or earnings adjusted for certain cash changes. These multiples are based on comparable multiples for publicly traded companies or other relevant prior transactions.

For fair value measurements of investments within the nuclear decommissioning trusts and rabbi trust funds, specifically the fixed income assets using significant other observable inputs and unobservable inputs, the primary valuation technique used is the market approach. External pricing vendors are designated for each of the asset classes in the nuclear decommissioning trusts and rabbi trust funds with each security discriminately assigned a primary pricing source, based on similar characteristics.

A market price secured from the primary source vendor is then evaluated by management in its valuation of the assets within the trusts. As a general approach, market pricing vendors gather market data (including indices and market research reports) and integrate relative credit information, observed market movements, and sector news into proprietary pricing models, pricing systems, and mathematical tools. Dealer quotes and other market information including live trading levels and pricing analysts' judgment are also obtained when available.

As of September 30, 2012, the fair value measurements of investments calculated at net asset value per share (or its equivalent), as well as the nature and risks of those investments, were as follows:

The NRC requires licensees of commissioned nuclear power reactors to establish a plan for providing reasonable assurance of funds for future decommissioning. Alabama Power and Georgia Power have external trust funds (the Funds) to comply with the NRC's regulations. The commingled funds in the nuclear decommissioning trusts are invested primarily in a diversified portfolio of high grade money market instruments, including, but not limited to, commercial paper, notes, repurchase agreements, and other evidences of indebtedness with a maturity not exceeding 13 months from the date of purchase. The commingled funds will, however, maintain a dollar-weighted average portfolio maturity of 90 days or less. The assets may be longer term investment grade fixed income obligations having a maximum five-year final maturity with put features or floating rates with a reset date of 13 months or less. The primary objective for the commingled funds is a high level of current income consistent with stability of principal and liquidity. The corporate bonds - commingled funds represent the investment of cash collateral received under the Funds' managers' securities lending program that can only be sold upon the return of the loaned securities. See Note 1 to the financial statements of Southern Company and Georgia Power under "Nuclear Decommissioning" in Item 8 of the Form 10-K for additional information.

Alabama Power's nuclear decommissioning trust includes investments in Trust-Owned Life Insurance (TOLI). The taxable nuclear decommissioning trust invests in the TOLI in order to minimize the impact of taxes on the portfolio and can draw on the value of the TOLI through death proceeds, loans against the cash surrender value, and/or the cash surrender value, subject to legal restrictions. The amounts reported in the table above reflect the fair value of investments the insurer has made in relation to the TOLI agreements. The nuclear decommissioning trust does not own the underlying investments, but the fair value of the investments approximates the cash surrender value of the TOLI policies. The investments made by the insurer are in commingled funds. The commingled funds primarily include investments in domestic and international equity securities and predominantly high-quality fixed income securities. These fixed income securities may include U.S. Treasury and government agency fixed income securities, non-U.S. government and agency fixed income securities, domestic and foreign corporate fixed income securities, and, to some degree, mortgage and asset backed securities. The passively managed funds seek to replicate the performance of a related index. The actively managed funds seek to exceed the performance of a related index through security analysis and selection.

Southern Company, Alabama Power, and Georgia Power continue to elect the option to fair value investment securities held in the nuclear decommissioning trust funds. For the three and nine months ended September 30, 2012, the change in fair value of the funds, which includes reinvested interest and dividends and excludes the Funds' expenses, is recorded as a regulatory liability and was an increase of $53 million and $116 million, respectively, for Southern Company, an increase of $27 million and $60 million, respectively, for Alabama Power, and an increase of $26 million and $56 million, respectively, for Georgia Power.

The money market funds are short-term investments of excess funds in various money market mutual funds, which are portfolios of short-term debt securities. The money market funds are regulated by the SEC and typically receive the highest rating from credit rating agencies. Regulatory and rating agency requirements for money market funds include minimum credit ratings and maximum maturities for individual securities and a maximum weighted average portfolio maturity. Redemptions are available on a same day basis up to the full amount of the investment in the money market funds.

At September 30, 2012, other financial instruments for which the carrying amount did not equal fair value were as follows: 

	Carrying Amount		Fair Value
	(in millions)
Long-term debt:
Southern Company	$	21,310	$	23,517
Alabama Power	$	6,130	$	6,955
Georgia Power	$	9,524	$	10,408
Gulf Power	$	1,246	$	1,382
Mississippi Power	$	1,767	$	1,890
Southern Power	$	1,307	$	1,485

The fair values are primarily Level 2 and are based on quoted market prices for the same or similar issues or on the current rates offered to Southern Company, Alabama Power, Georgia Power, Gulf Power, Mississippi Power, and Southern Power.

EFFECTIVE TAX RATE AND UNRECOGNIZED TAX BENEFITS

EFFECTIVE TAX RATE AND UNRECOGNIZED TAX BENEFITS

Effective Tax Rate

See Note 5 to the financial statements of each registrant in Item 8 of the Form 10-K for information on the effective income tax rate.

Southern Company

Southern Company's effective tax rate is typically lower than the statutory rate due to its employee stock plans' dividend deduction and non-taxable AFUDC equity.

Southern Company's effective tax rate was 35.3% for the nine months ended September 30, 2012 compared to 36.1% for the corresponding period in 2011. The decrease was primarily related to state income tax credits. See "Unrecognized Tax Benefits" herein for additional information.

Alabama Power

Alabama Power's effective tax rate was 38.8% for the nine months ended September 30, 2012 compared to 39.0% for the corresponding period in 2011. The decrease was primarily due to a decrease in Alabama state income taxes as a result of an increase in the state income tax deduction for federal income taxes paid.

Georgia Power

Georgia Power's effective tax rate was 35.8% for the nine months ended September 30, 2012 and for the corresponding period in 2011.

Gulf Power

Gulf Power's effective tax rate was 37.3% for the nine months ended September 30, 2012 compared to 36.6% for the corresponding period in 2011. The increase was primarily due to a decrease in non-taxable AFUDC equity.

Mississippi Power

Mississippi Power's effective tax rate was 26.7% for the nine months ended September 30, 2012 compared to 32.6% for the corresponding period in 2011. The decrease was primarily due to an increase in non-taxable AFUDC equity related to the Kemper IGCC construction.

Southern Power

Southern Power's effective tax rate was 34.4% for the nine months ended September 30, 2012 compared to 35.9% for the corresponding period in 2011. The decrease was primarily due to an increase in convertible investment tax credits and state tax credits.

Unrecognized Tax Benefits

Changes during 2012 for unrecognized tax benefits were as follows:

	Southern Company			Alabama Power			Georgia Power			Gulf Power			Mississippi Power		Southern Power
	(in millions)
Unrecognized tax benefits as of December 31, 2011	$	120		$	32		$	47		$	3		$	5	$	3

Balance as of September 30, 2012	$	98		$	29		$	25		$	3		$	5	$	3

The tax positions from current periods relate primarily to the tax accounting method change for repairs-generation assets. See "Tax Method of Accounting for Repairs" herein for additional information. The decreases in tax positions from prior periods primarily relate to state income tax credits. The reductions due to settlements relate to a settlement with the IRS of the calculation methodology for the production activities deduction.

Tax positions impacting the effective tax rate		$	38	$	69
Tax positions not impacting the effective tax rate		60		51
Balance of unrecognized tax benefits		$	98	$	120

The tax positions impacting the effective tax rate primarily relate to state income tax credits and a litigation settlement refund claim for Southern Company. See Note 5 to the financial statements of Southern Company under "Effective Tax Rate" in Item 8 of the Form 10-K for additional information. The tax positions not impacting the effective tax rate relate to the timing difference associated with the tax accounting method change for repairs-generation assets. See "Tax Method of Accounting for Repairs" herein for additional information. These amounts are presented on a gross basis without considering the related federal or state income tax impact.

Accrued interest for unrecognized tax benefits was as follows:

		Southern Company
	(in millions)
Interest accrued as of December 31, 2011		$	10
Interest reclassified due to settlements		(9		)
Interest accrued during the period		—
Balance as of September 30, 2012		$	1

All of the registrants classify interest on tax uncertainties as interest expense. The interest reclassified due to settlements is primarily associated with state income tax credits and a settlement with the IRS related to the calculation methodology for the production activities deduction.

None of the registrants accrued any penalties on uncertain tax positions.

It is reasonably possible that the amount of the unrecognized tax benefits associated with a majority of the registrants' unrecognized tax positions will significantly increase or decrease within the next 12 months. The resolution of the tax accounting method change for repairs-generation assets, as well as the conclusion or settlement of federal and state audits, could also impact the balances significantly. At this time, an estimate of the range of reasonably possible outcomes cannot be determined.

Tax Method of Accounting for Repairs

Southern Company submitted a tax accounting method change for repair costs associated with its subsidiaries' generation, transmission, and distribution systems with the filing of the 2009 federal income tax return in September 2010. In August 2011, the IRS issued a revenue procedure, which provides a safe harbor method of accounting that taxpayers may use to determine repair costs for transmission and distribution property. However, the IRS continues to work with the utility industry in an effort to resolve the repair costs for generation assets matter in a consistent manner for all utilities. In December 2011, the IRS published regulations on the deduction and capitalization of expenditures related to tangible property that generally apply for tax years beginning on or after January 1, 2012. The utility industry anticipates more detailed guidance concerning these regulations. Due to uncertainty regarding the ultimate resolution of the repair costs for generation assets, an unrecognized tax position has been recorded for the tax accounting method change for repairs-generation assets. The ultimate outcome of this matter cannot be determined at this time.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES

DERIVATIVES

Southern Company, the traditional operating companies, and Southern Power are exposed to market risks, primarily commodity price risk, interest rate risk, and occasionally foreign currency risk. To manage the volatility attributable to these exposures, each company nets its exposures, where possible, to take advantage of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to each company's policies in areas such as counterparty exposure and risk management practices. Each company's policy is that derivatives are to be used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress testing, and sensitivity analysis. Derivative instruments are recognized at fair value in the balance sheets as either assets or liabilities and are presented on a gross basis.

Energy-Related Derivatives

The traditional operating companies and Southern Power enter into energy-related derivatives to hedge exposures to electricity, gas, and other fuel price changes. However, due to cost-based rate regulations and other various cost recovery mechanisms, the traditional operating companies have limited exposure to market volatility in commodity fuel prices and prices of electricity. Each of the traditional operating companies manages fuel-hedging programs, implemented per the guidelines of their respective state PSCs, through the use of financial derivative contracts, which is expected to continue to mitigate price volatility. Southern Power has limited exposure to market volatility in commodity fuel prices and prices of electricity because its long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, Southern Power has been and may continue to be exposed to market volatility in energy-related commodity prices as a result of sales of uncontracted generating capacity.

To mitigate residual risks relative to movements in electricity prices, the traditional operating companies and Southern Power may enter into physical fixed-price or heat rate contracts for the purchase and sale of electricity through the wholesale electricity market. To mitigate residual risks relative to movements in gas prices, the traditional operating companies and Southern Power may enter into fixed-price contracts for natural gas purchases; however, a significant portion of contracts are priced at market.

Energy-related derivative contracts are accounted for under one of three methods:

• Regulatory Hedges — Energy-related derivative contracts which are designated as regulatory hedges relate primarily to the traditional operating companies' fuel hedging programs, where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as the underlying fuel is used in operations and ultimately recovered through the respective fuel cost recovery clauses.

• Cash Flow Hedges — Gains and losses on energy-related derivatives designated as cash flow hedges, which are mainly used to hedge anticipated purchases and sales and are initially deferred in OCI before being recognized in the statements of income in the same period as the hedged transactions, are reflected in earnings.

• Not Designated — Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

Some energy-related derivative contracts require physical delivery as opposed to financial settlement, and this type of derivative is both common and prevalent within the electric industry. When an energy-related derivative contract is settled physically, any cumulative unrealized gain or loss is reversed and the contract price is recognized in the respective line item representing the actual price of the underlying goods being delivered.

At September 30, 2012, the net volume of energy-related derivative contracts for natural gas positions for the Southern Company system, together with the longest hedge date over which the respective entity is hedging its exposure to the variability in future cash flows for forecasted transactions and the longest date for derivatives not designated as hedges, were as follows:

	Net Purchased mmBtu	Longest Hedge Date	Longest Non-Hedge Date
	(in millions)
Southern Company	270	2017	2017
Alabama Power	55	2017	—
Georgia Power	107	2017	—
Gulf Power	63	2017	—
Mississippi Power	36	2017	—
Southern Power	9	2012	2017

In addition to the volumes discussed in the above table, the traditional operating companies and Southern Power enter into physical natural gas supply contracts that provide the option to sell back excess gas due to operational constraints. The maximum expected volume of natural gas subject to such a feature is 7 million mmBtu for Southern Company, 1 million mmBtu for Alabama Power, 3 million mmBtu for Georgia Power, 1 million mmBtu for Gulf Power, 1 million mmBtu for Mississippi Power, and 1 million mmBtu for Southern Power.

For cash flow hedges, the amounts expected to be reclassified from OCI to revenue and fuel expense for the next 12-month period ending September 30, 2013 are immaterial for all registrants.

Interest Rate Derivatives

Southern Company and certain subsidiaries also enter into interest rate derivatives to hedge exposure to changes in interest rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness. Derivatives related to existing variable rate securities or forecasted transactions are accounted for as cash flow hedges where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings, with any ineffectiveness recorded directly to earnings. Derivatives related to existing fixed rate securities are accounted for as fair value hedges, where the derivatives' fair value gains or losses and hedged items' fair value gains or losses are both recorded directly to earnings, providing an offset with any difference representing ineffectiveness.

At September 30, 2012, the following interest rate derivatives were outstanding:

	Notional Amount		Interest Rate Received		Interest Rate Paid			Hedge Maturity Date	Fair Value Gain (Loss) September 30, 2012
	(in millions)								(in millions)

The following table reflects the estimated pre-tax gains (losses) that will be reclassified from OCI to interest expense for the next 12-month period ending September 30, 2013, together with the longest date that total deferred gains and losses are expected to be amortized into earnings.

Foreign Currency Derivatives

Southern Company and certain subsidiaries may enter into foreign currency derivatives to hedge exposure to changes in foreign currency exchange rates arising from purchases of equipment denominated in a currency other than U.S. dollars. Derivatives related to a firm commitment in a foreign currency transaction are accounted for as fair value hedges where the derivatives' fair value gains or losses and the hedged items' fair value gains or losses are both recorded directly to earnings. Derivatives related to a forecasted transaction are accounted for as a cash flow hedge where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings. Any ineffectiveness is typically recorded directly to earnings; however, Mississippi Power has regulatory approval allowing it to defer any ineffectiveness associated with firm commitments related to the Kemper IGCC to a regulatory asset. The derivatives employed as hedging instruments are structured to minimize ineffectiveness.

At September 30, 2012, the following foreign currency derivatives were outstanding:

	Notional Amount	Forward Rate		Hedge Maturity Date	Fair Value Gain (Loss) September 30, 2012(c)
	(in millions)				(in millions)

For the three and nine months ended September 30, 2012 and September 30, 2011, the pre-tax effects of interest rate derivatives designated as fair value hedging instruments on Southern Company's statements of income were immaterial.

For the three and nine months ended September 30, 2012, the pre-tax effects of foreign currency derivatives designated as fair value hedging instruments on Southern Company's and Mississippi Power's statements of income were immaterial. For the three and nine months ended September 30, 2011, the pre-tax losses of foreign currency derivatives designated as fair value hedging instruments on Southern Company's and Mississippi Power's statements of income were $(3) million and $(2) million, respectively. The pre-tax effects of foreign currency derivatives designated as fair value hedging instruments on both Southern Company's and Mississippi Power's statements of income were offset with changes in the fair value of the purchase commitment related to equipment purchases; therefore, there was no impact on Southern Company's or Mississippi Power's statements of income.

For the three months ended September 30, 2012 and 2011, the pre-tax effects of interest rate derivatives designated as cash flow hedging instruments on the statements of income were as follows:

For the three and nine months ended September 30, 2012 and 2011, the pre-tax effects of energy-related derivatives designated as cash flow hedging instruments on the statements of income were immaterial for all registrants.

There was no material ineffectiveness recorded in earnings for any registrant for any period presented.

For Southern Power's energy-related derivatives not designated as hedging instruments, a substantial portion of the pre-tax realized and unrealized gains and losses is associated with hedging fuel price risk of certain PPA customers and has no impact on net income or on fuel expense as presented in Southern Company's and Southern Power's statements of income. As a result, for the three and nine months ended September 30, 2012 and 2011, the pre-tax effects of energy-related derivatives not designated as hedging instruments on Southern Company's and Southern Power's statements of income were immaterial.

For the three and nine months ended September 30, 2012, the pre-tax effects of foreign currency derivatives not designated as hedging instruments were recorded as regulatory assets and liabilities and were immaterial for Southern Company and Mississippi Power.

Contingent Features

The registrants do not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain derivatives that could require collateral, but not accelerated payment, in the event of various credit rating changes of certain Southern Company subsidiaries. At September 30, 2012, the fair value of derivative liabilities with contingent features, by registrant, was as follows:

	Southern Company		Alabama Power		Georgia Power		Gulf Power		Mississippi Power		Southern Power
					(in millions)
Derivative liabilities	$	10	$	2	$	4	$	2	$	2	$	—

At September 30, 2012, the registrants had no collateral posted with their derivative counterparties. If collateral is required, fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral are not offset against fair value amounts recognized for derivatives executed with the same counterparty under the same master netting arrangement. The maximum potential collateral requirements arising from the credit-risk-related contingent features, at a rating below BBB- and/or Baa3, is $10 million for each registrant. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. For the traditional operating companies and Southern Power, included in these amounts are certain agreements that could require collateral in the event that one or more Power Pool participant has a credit rating change to below investment grade.

Southern Company, the traditional operating companies, and Southern Power are exposed to losses related to financial instruments in the event of counterparties' nonperformance. Southern Company, the traditional operating companies, and Southern Power only enter into agreements and material transactions with counterparties that have investment grade credit ratings by Moody's and S&P or with counterparties who have posted collateral to cover potential credit exposure. Southern Company, the traditional operating companies, and Southern Power have also established risk management policies and controls to determine and monitor the creditworthiness of counterparties in order to mitigate Southern Company's, the traditional operating companies', and Southern Power's exposure to counterparty credit risk. Therefore, Southern Company, the traditional operating companies, and Southern Power do not anticipate a material adverse effect on the financial statements as a result of counterparty nonperformance.

However, due to cost-based rate regulations and other various cost recovery mechanisms, the traditional operating companies have limited exposure to market volatility in commodity fuel prices and prices of electricity. Each of the traditional operating companies manages fuel-hedging programs, implemented per the guidelines of their respective state PSCs, through the use of financial derivative contracts, which is expected to continue to mitigate price volatility. Southern Power has limited exposure to market volatility in commodity fuel prices and prices of electricity because its long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, Southern Power has been and may continue to be exposed to market volatility in energy-related commodity prices as a result of sales of uncontracted generating capacity.

To mitigate residual risks relative to movements in electricity prices, the traditional operating companies and Southern Power may enter into physical fixed-price or heat rate contracts for the purchase and sale of electricity through the wholesale electricity market. To mitigate residual risks relative to movements in gas prices, the traditional operating companies and Southern Power may enter into fixed-price contracts for natural gas purchases; however, a significant portion of contracts are priced at market.

Energy-related derivative contracts are accounted for under one of three methods:

• Regulatory Hedges — Energy-related derivative contracts which are designated as regulatory hedges relate primarily to the traditional operating companies' fuel hedging programs, where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as the underlying fuel is used in operations and ultimately recovered through the respective fuel cost recovery clauses.

• Cash Flow Hedges — Gains and losses on energy-related derivatives designated as cash flow hedges, which are mainly used to hedge anticipated purchases and sales and are initially deferred in OCI before being recognized in the statements of income in the same period as the hedged transactions, are reflected in earnings.

• Not Designated — Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

Some energy-related derivative contracts require physical delivery as opposed to financial settlement, and this type of derivative is both common and prevalent within the electric industry. When an energy-related derivative contract is settled physically, any cumulative unrealized gain or loss is reversed and the contract price is recognized in the respective line item representing the actual price of the underlying goods being delivered.

At September 30, 2012, the net volume of energy-related derivative contracts for natural gas positions for the Southern Company system, together with the longest hedge date over which the respective entity is hedging its exposure to the variability in future cash flows for forecasted transactions and the longest date for derivatives not designated as hedges, were as follows:

	Net Purchased mmBtu	Longest Hedge Date	Longest Non-Hedge Date
	(in millions)
Southern Company	270	2017	2017
Alabama Power	55	2017	—
Georgia Power	107	2017	—
Gulf Power	63	2017	—
Mississippi Power	36	2017	—
Southern Power	9	2012	2017

In addition to the volumes discussed in the above table, the traditional operating companies and Southern Power enter into physical natural gas supply contracts that provide the option to sell back excess gas due to operational constraints. The maximum expected volume of natural gas subject to such a feature is 7 million mmBtu for Southern Company, 1 million mmBtu for Alabama Power, 3 million mmBtu for Georgia Power, 1 million mmBtu for Gulf Power, 1 million mmBtu for Mississippi Power, and 1 million mmBtu for Southern Power.

For cash flow hedges, the amounts expected to be reclassified from OCI to revenue and fuel expense for the next 12-month period ending September 30, 2013 are immaterial for all registrants.

Interest Rate Derivatives

Southern Company and certain subsidiaries also enter into interest rate derivatives to hedge exposure to changes in interest rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness. Derivatives related to existing variable rate securities or forecasted transactions are accounted for as cash flow hedges where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings, with any ineffectiveness recorded directly to earnings. Derivatives related to existing fixed rate securities are accounted for as fair value hedges, where the derivatives' fair value gains or losses and hedged items' fair value gains or losses are both recorded directly to earnings, providing an offset with any difference representing ineffectiveness.

At September 30, 2012, the following interest rate derivatives were outstanding:

	Notional Amount		Interest Rate Received		Interest Rate Paid			Hedge Maturity Date	Fair Value Gain (Loss) September 30, 2012
	(in millions)								(in millions)
Cash flow hedges of forecasted transactions
Alabama Power	$	300	3-month LIBOR		2.90	%	(a)	December 2022	$	(32	)
Fair value hedges of existing debt
Southern Company	350		4.15	%	3-month LIBOR  + 1.96%		(a)	May 2014	13
Total	$	650							$	(19	)

(a) Weighted average

The following table reflects the estimated pre-tax gains (losses) that will be reclassified from OCI to interest expense for the next 12-month period ending September 30, 2013, together with the longest date that total deferred gains and losses are expected to be amortized into earnings.

Registrant	Estimated Gain (Loss) to be Reclassified for the 12 Months Ending September 30, 2013			Total Deferred Gains (Losses) Amortized  Through

Foreign Currency Derivatives

Foreign Currency Derivatives

Southern Company and certain subsidiaries may enter into foreign currency derivatives to hedge exposure to changes in foreign currency exchange rates arising from purchases of equipment denominated in a currency other than U.S. dollars. Derivatives related to a firm commitment in a foreign currency transaction are accounted for as fair value hedges where the derivatives' fair value gains or losses and the hedged items' fair value gains or losses are both recorded directly to earnings. Derivatives related to a forecasted transaction are accounted for as a cash flow hedge where the effective portion of the derivatives' fair value gains or losses is recorded in OCI and is reclassified into earnings at the same time the hedged transactions affect earnings. Any ineffectiveness is typically recorded directly to earnings; however, Mississippi Power has regulatory approval allowing it to defer any ineffectiveness associated with firm commitments related to the Kemper IGCC to a regulatory asset. The derivatives employed as hedging instruments are structured to minimize ineffectiveness.

Commitments and Contingencies Disclosure [Abstract]

CONTINGENCIES AND REGULATORY MATTERS

CONTINGENCIES AND REGULATORY MATTERS

See Note 3 to the financial statements of the registrants in Item 8 of the Form 10-K for information relating to various lawsuits, other contingencies, and regulatory matters.

General Litigation Matters

Each registrant is subject to certain claims and legal actions arising in the ordinary course of business. In addition, business activities of Southern Company's subsidiaries are subject to extensive governmental regulation related to public health and the environment, such as regulation of air emissions and water discharges. Litigation over environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental requirements such as air quality and water standards, has increased generally throughout the U.S. In particular, personal injury and other claims for damages caused by alleged exposure to hazardous materials, and common law nuisance claims for injunctive relief and property damage allegedly caused by greenhouse gas and other emissions, have become more frequent. The ultimate outcome of such pending or potential litigation against each registrant and any subsidiaries cannot be predicted at this time; however, for current proceedings not specifically reported herein or in Note 3 to the financial statements of each registrant in Item 8 of the Form 10-K, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on such registrant's financial statements.

Insurance Recovery

Mirant Corporation (Mirant) was an energy company with businesses that included independent power projects and energy trading and risk management companies in the U.S. and other countries. Mirant was a wholly-owned subsidiary of Southern Company until its initial public offering in 2000. In 2001, Southern Company completed a spin-off to its stockholders of its remaining ownership, and Mirant became an independent corporate entity.

In 2003, Mirant and certain of its affiliates filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. In 2005, Mirant, as a debtor in possession, and the unsecured creditors' committee filed a complaint against Southern Company. Later in 2005, this complaint was transferred to MC Asset Recovery, LLC (MC Asset Recovery) as part of Mirant's plan of reorganization. In 2009, Southern Company entered into a settlement agreement with MC Asset Recovery to resolve this action. The settlement included an agreement where Southern Company paid MC Asset Recovery $202 million. Southern Company filed an insurance claim in 2009 to recover a portion of this settlement and received a nontaxable $25 million payment from its insurance provider on June 14, 2012. Additionally, legal fees related to this insurance settlement totaled approximately $6 million. As a result, the net reduction to expense for this insurance settlement was approximately $19 million.

Environmental Matters

New Source Review Actions

In 1999, the EPA brought a civil action in the U.S. District Court for the Northern District of Georgia against certain Southern Company subsidiaries, including Alabama Power and Georgia Power, alleging that these subsidiaries had violated the NSR provisions of the Clean Air Act and related state laws at certain coal-fired generating facilities. The EPA alleged NSR violations at five coal-fired generating facilities operated by Alabama Power, including a unit co-owned by Mississippi Power, and three coal-fired generating facilities operated by Georgia Power, including a unit co-owned by Gulf Power. The civil action sought penalties and injunctive relief, including an order requiring installation of the best available control technology at the affected units. The case against Georgia Power (including claims related to the unit co-owned by Gulf Power) was administratively closed in 2001 and has not been reopened. After Alabama Power was dismissed from the original action, the EPA filed a separate action in 2001 against Alabama Power (including claims related to the unit co-owned by Mississippi Power) in the U.S. District Court for the Northern District of Alabama.

In 2006, the U.S. District Court for the Northern District of Alabama entered a consent decree, resolving claims relating to the alleged NSR violations at Plant Miller. In September 2010, the EPA dismissed five of its eight remaining claims against Alabama Power, leaving only three claims, including one relating to the unit co-owned by Mississippi Power. In March 2011, the U.S. District Court for the Northern District of Alabama granted Alabama Power summary judgment on all remaining claims and dismissed the case with prejudice. That judgment is on appeal to the U.S. Court of Appeals for the Eleventh Circuit. On February 23, 2012, the EPA filed a motion in the U.S. District Court for the Northern District of Alabama seeking vacatur of the judgment and recusal of the judge in the case involving Alabama Power (including claims related to a unit co-owned by Mississippi Power). The U.S. District Court for the Northern District of Alabama has not ruled on the EPA's motion seeking vacatur of the judgment.

Southern Company and each traditional operating company believe each such traditional operating company complied with applicable laws and regulations in effect at the time the work in question took place. The Clean Air Act authorizes maximum civil penalties of $25,000 to $37,500 per day, per violation, depending on the date of the alleged violation. An adverse outcome could require substantial capital expenditures that cannot be determined at this time and could possibly require payment of substantial penalties. Such expenditures could affect future results of operations, cash flows, and financial condition if such costs are not recovered through regulated rates. The ultimate outcome of these matters cannot be determined at this time.

Climate Change Litigation

Kivalina Case

In 2008, the Native Village of Kivalina and the City of Kivalina filed a lawsuit in the U.S. District Court for the Northern District of California against several electric utilities (including Southern Company), several oil companies, and a coal company. The plaintiffs allege that the village is being destroyed by erosion allegedly caused by global warming that the plaintiffs attribute to emissions of greenhouse gases by the defendants. The plaintiffs assert claims for public and private nuisance and contend that some of the defendants (including Southern Company) acted in concert and are therefore jointly and severally liable for the plaintiffs' damages. The suit seeks damages for lost property values and for the cost of relocating the village, which is alleged to be $95 million to $400 million. In 2009, the U.S. District Court for the Northern District of California granted the defendants' motions to dismiss the case. On September 21, 2012, the U.S. Court of Appeals for the Ninth Circuit upheld the U.S. District Court for the Northern District of California's dismissal of the case. On October 8, 2012, the plaintiffs filed for review of the decision by the U.S. Court of Appeals for the Ninth Circuit. Southern Company believes that these claims are without merit. While Southern Company believes the likelihood of loss is remote based on existing case law, it is not possible to predict with certainty whether Southern Company will incur any liability in connection with this matter. The ultimate outcome of this matter cannot be determined at this time.

Hurricane Katrina Case

In 2005, immediately following Hurricane Katrina, a lawsuit was filed in the U.S. District Court for the Southern District of Mississippi by Ned Comer on behalf of Mississippi residents seeking recovery for property damage and personal injuries caused by Hurricane Katrina. In 2006, the plaintiffs amended the complaint to include Southern Company and many other electric utilities, oil companies, chemical companies, and coal producers. The plaintiffs allege that the defendants contributed to climate change, which contributed to the intensity of Hurricane Katrina. In 2007, the U.S. District Court for the Southern District of Mississippi dismissed the case. On appeal to the U.S. Court of Appeals for the Fifth Circuit, a three-judge panel reversed the U.S. District Court for the Southern District of Mississippi, holding that the case could proceed, but, on rehearing, the full U.S. Court of Appeals for the Fifth Circuit dismissed the plaintiffs' appeal, resulting in reinstatement of the decision of the U.S. District Court for the Southern District of Mississippi in favor of the defendants. In May 2011, the plaintiffs filed an amended version of their class action complaint, arguing that the earlier dismissal was on procedural grounds and under Mississippi law

the plaintiffs have a right to re-file. The amended complaint was also filed against numerous chemical, coal, oil, and utility companies, including Alabama Power, Georgia Power, Gulf Power, and Southern Power. On March 20, 2012, the U.S. District Court for the Southern District of Mississippi dismissed the plaintiffs' amended complaint. On April 16, 2012, the plaintiffs appealed the case to the U.S. Court of Appeals for the Fifth Circuit. Each Southern Company entity named in the lawsuit believes that these claims are without merit. While each Southern Company entity named in the lawsuit believes the likelihood of loss is remote based on existing case law, it is not possible to predict with certainty whether any Southern Company entity named in the lawsuit will incur any liability in connection with this matter. The ultimate outcome of this matter cannot be determined at this time.

Environmental Remediation

The Southern Company system must comply with environmental laws and regulations that cover the handling and disposal of waste and releases of hazardous substances. Under these various laws and regulations, the Southern Company system could incur substantial costs to clean up properties. The traditional operating companies have each received authority from their respective state PSCs to recover approved environmental compliance costs through regulatory mechanisms. These rates are adjusted annually or as necessary within limits approved by the state PSCs.

Georgia Power's environmental remediation liability as of September 30, 2012 was $20 million. Georgia Power has been designated or identified as a potentially responsible party (PRP) at sites governed by the Georgia Hazardous Site Response Act and/or by the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), including a large site in Brunswick, Georgia on the CERCLA National Priorities List (NPL). The parties have completed the removal of wastes from the Brunswick site as ordered by the EPA. Additional cleanup and claims for recovery of natural resource damages at this site or for the assessment and potential cleanup of other sites on the Georgia Hazardous Sites Inventory and the CERCLA NPL are anticipated.

In 2008, the EPA advised Georgia Power that it has been designated as a PRP at the Ward Transformer Superfund site located in Raleigh, North Carolina. Numerous other entities have also received notices regarding this site from the EPA. In September 2011, the EPA issued a unilateral administrative order (UAO) to Georgia Power and 22 other parties, ordering specific remedial action of certain areas at the Ward Transformer Superfund site. Georgia Power does not believe it is a liable party under CERCLA based on its alleged connection to the site. As a result, in November 2011, Georgia Power filed a response with the EPA indicating that Georgia Power is not willing to undertake the work set forth in the UAO because Georgia Power has sufficient cause to believe it is not a liable party. In November 2011, the EPA sent Georgia Power a letter stating that the EPA does not consider Georgia Power to be in compliance with the UAO. The EPA also stated that it is considering enforcement options against Georgia Power and other UAO recipients who are not complying with the UAO. The EPA may seek to enforce the UAO in court pursuant to its enforcement authority under CERCLA and may seek recovery of its costs in undertaking the UAO work. If the court determines that a respondent failed to comply with the UAO without sufficient cause, the EPA may also seek civil penalties of up to $37,500 per day for the violation and punitive damages of up to three times the costs incurred by the EPA as a result of the party's failure to comply with the UAO.

In addition to the EPA's action at the Ward Transformer Superfund site, in 2009, Georgia Power, along with many other parties, was sued by several existing PRPs for cost recovery for a removal action that is currently taking place. Georgia Power and numerous other defendants moved for a dismissal of these lawsuits. The court denied the dismissal of the lawsuits in March 2010 but granted Georgia Power's motion regarding the dismissal of the claim pertaining to the plaintiffs' joint and several liability.

The ultimate outcome of the Brunswick CERCLA NPL and Ward Transformer Superfund site matters will depend upon the success of defenses asserted, the ultimate number of PRPs participating in the cleanup, and numerous other factors and cannot be determined at this time; however, as a result of the regulatory treatment described in Note 1 to the financial statements of Georgia Power under "Environmental Remediation" in Item 8 of the Form 10-K, they are not expected to have a material impact on Southern Company's or Georgia Power's financial statements.

Gulf Power's environmental remediation liability includes estimated costs of environmental remediation projects of approximately $61 million as of September 30, 2012. These estimated costs primarily relate to site closure criteria by the Florida Department of Environmental Protection (FDEP) for potential impacts to soil and groundwater from herbicide applications at Gulf Power substations. The schedule for completion of the remediation projects is subject to FDEP approval. The projects have been approved by the Florida PSC for recovery through Gulf Power's environmental cost recovery clause; therefore, there was no impact on net income as a result of these estimates.

In 2003, the Texas Commission on Environmental Quality (TCEQ) designated Mississippi Power as a PRP at a site in Texas. The site was owned by an electric transformer company that handled Mississippi Power's transformers as well as those of many other entities. The site owner is bankrupt and the State of Texas has entered into an agreement with Mississippi Power and several other utilities to investigate and remediate the site. The feasibility study/presumptive remedy document was originally filed with TCEQ in June 2011. TCEQ approved the feasibility study on September 17, 2012, but the ultimate remedy to be pursued remains under consideration by the agency. Amounts expensed and accrued related to this work were not material. Hundreds of entities have received notices from the TCEQ requesting their participation in the anticipated site remediation. The final impact of this matter on Mississippi Power will depend upon further environmental assessment and the ultimate number of potentially responsible parties. The remediation expenses incurred by Mississippi Power are expected to be recovered through the ECO Plan.

The final outcome of these matters cannot be determined at this time. However, based on the currently known conditions at these sites and the nature and extent of activities relating to these sites, management of Southern Company, Georgia Power, Gulf Power, and Mississippi Power does not believe that additional liabilities, if any, at these sites would be material to their respective financial statements.

Nuclear Fuel Disposal Cost Litigation

Alabama Power and Georgia Power have contracts with the U.S., acting through the DOE, that provide for the permanent disposal of spent nuclear fuel. The DOE failed to begin disposing of spent nuclear fuel in 1998 as required by the contracts, and Alabama Power and Georgia Power are pursuing legal remedies against the government for breach of contract.

In 2007, the U.S. Court of Federal Claims awarded Georgia Power approximately $30 million, based on its ownership interests, and awarded Alabama Power approximately $17 million, representing substantially all of the Southern Company system's direct costs of the expansion of spent nuclear fuel storage facilities at Plants Farley and Hatch and Plant Vogtle Units 1 and 2 from 1998 through 2004.

In 2008, the government filed an appeal and, in March 2011, the U.S. Court of Appeals for the Federal Circuit issued an order in which it affirmed the damage award to Alabama Power, but remanded the Georgia Power portion of the proceeding back to the U.S. Court of Federal Claims for reconsideration of the damages amount in light of the spent nuclear fuel acceptance rates adopted in a separate proceeding by the U.S. Court of Appeals for the Federal Circuit. In July 2011, the court entered final judgment in favor of Alabama Power and awarded Alabama Power approximately $17 million. In April 2012, the award was credited to cost of service for the benefit of Alabama Power customers.

On April 5, 2012, Georgia Power and the government entered into a stipulation to conclude this litigation, which provided for judgment in favor of Georgia Power and awarded Georgia Power approximately $27 million in damages, based on its ownership interests. On April 5, 2012, the stipulation was approved by the U.S. Court of Federal Claims. The proceeds were received and credited to the Georgia Power accounts where the original costs were charged and were used to reduce rate base, fuel, and cost of service for the benefit of Georgia Power customers.

In 2008, a second claim against the government was filed for damages incurred after December 31, 2004 (the court-mandated cut-off in the original claim) due to the government's alleged continuing breach of contract. The complaint does not contain any specific dollar amount for recovery of damages. Damages will continue to accumulate until the issue is resolved or the storage is provided. No amounts have been recognized in the financial statements as of September 30, 2012 for the second claim. The final outcome of this matter cannot be determined at this time.

Sufficient pool storage capacity for spent fuel is available at Plant Vogtle Units 1 and 2 to maintain full-core discharge capability for both units into 2014. Construction of an on-site dry storage facility at Plant Vogtle Units 1 and 2 has begun and is expected to be operational in sufficient time to maintain pool full-core discharge capability. At Plants Hatch and Farley, on-site dry spent fuel storage facilities are operational and can be expanded to accommodate spent fuel through the expected life of each plant.

FERC Matters

See Note 3 to the financial statements of Mississippi Power under "FERC Matters" in Item 8 of the Form 10-K for additional information regarding Mississippi Power's request for revised rates related to the wholesale Municipal and Rural Associations (MRA) cost-based electric tariff. See Note 3 to the financial statements of Southern Company and Mississippi Power under "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K for information regarding Mississippi Power's construction of the Kemper IGCC.

On January 20, 2012, Mississippi Power reached a settlement agreement with its wholesale customers, which was executed by all parties on March 9, 2012. The settlement agreement provides that base rates under the cost-based electric tariff will increase by approximately $22.6 million over a 12-month period with revised rates effective April 1, 2012. In 2012, the amount of base rate revenues to be received from the agreed upon increase will be approximately $17.0 million. On March 12, 2012, Mississippi Power filed an unopposed motion to place wholesale MRA interim rates into effect pending approval of the settlement agreement between the parties by the FERC. On March 28, 2012, the FERC approved the motion to place interim rates into effect beginning in May 2012. On September 27, 2012, Mississippi Power, with its wholesale customers, filed a final settlement agreement with the FERC. On November 5, 2012, the settlement judge certified the settlement agreement to the FERC with the recommendation that it be approved. A decision by the FERC is expected by the end of 2012. The ultimate outcome of this matter cannot be determined at this time.

In accordance with the terms of the 2010 ARP, on November 1, 2012, Georgia Power filed the following tariff adjustments with the Georgia PSC to become effective on January 1, 2013:

• Increase the DSM tariffs by approximately $16 million;

• Increase the traditional base tariffs by approximately $58 million to recover the revenue requirements for Plant McDonough-Atkinson Units 4, 5, and 6 for the period through December 31, 2013, which also reflects a separate settlement agreement associated with the June 30, 2011 quarterly construction monitoring report for Plant McDonough-Atkinson (see Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Other Construction" and "Construction – Other Construction," respectively, in Item 8 of the Form 10-K for additional information); and

• Increase the MFF tariff, consistent with the adjustments above, as well as those related to the IFR and NCCR tariff adjustments described under "Fuel Cost Recovery" and "Nuclear Construction," respectively, herein.

Fuel Cost Recovery

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Fuel Cost Recovery" and "Retail Regulatory Matters – Fuel Cost Recovery," respectively, in Item 8 of the Form 10-K for additional information.

On June 21, 2012, the Georgia PSC approved a 19% decrease in Georgia Power's fuel cost recovery rates, which reduced annual billings by $567 million effective June 1, 2012. The decrease in fuel costs resulted from lower natural gas prices as a result of increased natural gas supplies.

As of September 30, 2012, Georgia Power's fuel cost over recovery balance totaled $199 million. This balance is slightly below the $200 million required to automatically trigger the Georgia PSC's approved IFR adjustment mechanism. On November 1, 2012, Georgia Power filed a request with the Georgia PSC to reduce fuel cost recovery rates, effective January 1, 2013, using the IFR process. The requested reduction would reduce annual billings by approximately $122 million. In accordance with the IFR process, the Georgia PSC will have 30 days to consider Georgia Power's request. The ultimate outcome of this matter cannot be determined at this time.

The over recovered fuel costs at September 30, 2012 are included in current liabilities and other deferred credits and liabilities on Southern Company's and Georgia Power's Condensed Balance Sheets herein. At December 31, 2011, Georgia Power's under recovered fuel balance totaled $137 million and is included in current assets on Southern Company's and Georgia Power's Condensed Balance Sheets herein. Fuel cost recovery revenues as recorded on the financial statements are adjusted for differences in actual recoverable fuel costs and amounts billed in current regulated rates. Accordingly, any changes in the billing factor will not have a significant effect on Southern Company's or Georgia Power's revenues or net income, but will affect cash flow.

2011 Integrated Resource Plan Update

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – 2011 Integrated Resource Plan Update" and "Retail Regulatory Matters – 2011 Integrated Resource Plan Update," respectively, in Item 8 of the Form 10-K for additional information.

On March 20, 2012, the Georgia PSC approved Georgia Power's request to decertify and retire two coal-fired generation units at Plant Branch as of October 31, 2013 and December 31, 2013 and an oil-fired unit at Plant Mitchell as of March 26, 2012, which was included in Georgia Power's 2011 IRP Update. The Georgia PSC also approved three PPAs totaling 998 MWs with Southern Power for capacity and energy that will commence in 2015 and end in 2030. The PPAs remain subject to FERC approval. The ultimate outcome of this matter cannot be determined at this time.

Separately, on October 16, 2012, the Georgia PSC approved a 50 MW PPA with a Qualifying Facility for capacity and energy that will commence in 2015 and end in 2035. This PPA is expected to result in contractual obligations of approximately $13 million in 2015, $16 million in 2016, and $376 million in total thereafter.

Advanced Solar Initiative

Georgia Power filed a new solar initiative with the Georgia PSC on September 26, 2012. If approved, Georgia Power may acquire up to 210 MWs of additional solar capacity over a three-year period through long-term contracts. The ultimate outcome of this matter cannot be determined at this time.

Nuclear Construction

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Nuclear Construction" and "Construction – Nuclear," respectively, in Item 8 of the Form 10-K for additional information regarding Georgia Power's construction of Plant Vogtle Units 3 and 4.

On February 16, 2012, a group of petitioners who had intervened in the NRC's combined construction and operating licenses (COLs) proceedings for Plant Vogtle Units 3 and 4 filed a petition in the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review and a stay of the NRC's issuance of the COLs. In addition, on February 16, 2012, another group of petitioners filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit seeking judicial review of the NRC's certification of the Westinghouse Design Control Document, as amended (DCD). On April 3, 2012, the U.S. Court of Appeals for the District of Columbia Circuit granted a motion filed by these two groups of petitioners to consolidate their challenges. On April 18, 2012, another group of petitioners filed a motion to stay the effectiveness of the order issuing the COLs for Plant Vogtle Units 3 and 4 with the U.S. District Court for the District of Columbia. On July 11, 2012, the U.S. Court of Appeals for the District of Columbia Circuit denied the petitioners' motion to stay the effectiveness of the COLs. Georgia Power has intervened in and intends to vigorously contest these petitions.

In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4. In addition, the Georgia PSC voted to approve inclusion of the related CWIP accounts in rate base. Also in 2009, the Governor of the State of Georgia signed into law the Georgia Nuclear Energy Financing Act that allows Georgia Power to recover financing costs for nuclear construction projects by including the related CWIP accounts in rate base during the construction period. With respect to Plant Vogtle Units 3 and 4, this legislation allows Georgia Power to recover projected financing costs of approximately $1.7 billion during the construction period beginning in 2011, which reduces the projected in-service cost to approximately $4.4 billion. The Georgia PSC has ordered Georgia Power to report against this total certified cost of approximately $6.1 billion. On August 21, 2012, the Georgia PSC voted to approve Georgia Power's sixth semi-annual construction monitoring report including total costs of $2.0 billion for Plant Vogtle Units 3 and 4 incurred through December 31, 2011. Georgia Power will continue to file construction monitoring reports by February 28 and August 31 of each year during the construction period.

In addition, in December 2010, the Georgia PSC approved Georgia Power's NCCR tariff. The NCCR tariff became effective January 1, 2011 and adjustments are filed with the Georgia PSC on November 1 of each year to become effective on January 1 of the following year. On November 1, 2012, Georgia Power filed to increase the NCCR tariff by approximately $50 million effective January 1, 2013. Through the NCCR tariff, Georgia Power is collecting and amortizing to earnings approximately $91 million of financing costs, capitalized in 2009 and 2010, over the five-year period ending December 31, 2015, in addition to the ongoing financing costs. At September 30, 2012, approximately $59 million of these 2009 and 2010 costs remained in CWIP.

Georgia Power, Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and the City of Dalton, Georgia, an incorporated municipality in the State of Georgia acting by and through its Board of Water, Light, and Sinking Fund Commissioners (collectively, Owners) and Westinghouse and Stone & Webster, Inc. (collectively, Contractor) have established both informal and formal dispute resolution procedures in accordance with the engineering, procurement, and construction agreement for Plant Vogtle Units 3 and 4 (Vogtle 3 and 4 Agreement) in order to resolve issues arising during the course of constructing a project of this magnitude. The Contractor and Georgia Power (on behalf of the Owners) have successfully initiated both formal and informal claims through these procedures, including ongoing claims, to resolve disputes. When matters are not resolved through these procedures, the parties may proceed to litigation. The Contractor and the Owners are involved in litigation with respect to certain claims that have not been resolved through the formal dispute resolution process.

During the course of construction activities, issues have arisen that may impact the project budget and schedule. The most significant issues relate to costs associated with design changes to the DCD and costs associated with delays in the project schedule related to the timing of approval of the DCD and issuance of the COLs by the NRC. The Owners and the Contractor have begun negotiations regarding these issues, including the assertion by the Contractor that the Owners are responsible for these costs under the terms of the Vogtle 3 and 4 Agreement. Through correspondence sent to the Owners, the Contractor provided its proposed adjustment to the contract price and initiated the formal dispute resolution process. The Contractor's estimated adjustment attributable to Georgia Power (based on Georgia Power's ownership interest) is approximately $425 million (in 2008 dollars) with respect to these issues. Georgia Power has not agreed with the amount of these proposed adjustments or that the Owners have responsibility for any costs related to these issues. On November 1, 2012, Georgia Power and the other Owners filed suit against the Contractor in the U.S. District Court for the Southern District of Georgia, seeking a declaratory judgment that the Owners are not responsible for the costs related to these issues. Also on November 1, 2012, the Contractor filed suit against Georgia Power and the other Owners in the U.S. District Court for the District of Columbia, alleging the Owners are responsible for the costs related to these issues and seeking payment from the Owners of the full amount of these costs. While litigation has commenced, Georgia Power expects negotiations with the Contractor to continue with respect to cost and schedule during which time the parties will attempt to reach a mutually acceptable compromise of their positions. Georgia Power intends to vigorously defend its positions. If these costs ultimately are imposed upon the Owners, Georgia Power would seek

an amendment to the certified cost of Plant Vogtle Units 3 and 4, if necessary. In connection with these negotiations, the Owners are evaluating whether maintaining the currently scheduled commercial operation dates of 2016 and 2017 remains in the best interest of their customers. Additional claims by the Contractor or Georgia Power (on behalf of the Owners) are expected to arise throughout the construction of Plant Vogtle Units 3 and 4.

In addition, there are processes in place that are designed to assure compliance with the design requirements specified in the DCD and the COLs, including rigorous inspection by Southern Nuclear and the NRC that occurs throughout construction. During a routine inspection in April 2012, the NRC identified that certain details of the rebar construction in the Plant Vogtle Unit 3 nuclear island were not consistent with the DCD. In May 2012, Southern Nuclear received an official notice of violation relating to these findings from the NRC. The design changes were determined to have minimal safety significance and, on October 18, 2012, the NRC approved a license amendment request to clarify that the nuclear island concrete and rebar construction will conform to NRC requirements. Various inspection and other issues are expected to arise from time to time as construction proceeds,which may result in additional license amendments or require other resolution.

There are pending technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4, including legal challenges to the NRC issuance of the COLs and certification of the DCD. Similar additional challenges at the state and federal level are expected as construction proceeds.

The ultimate outcome of these matters cannot be determined at this time.

Other Construction

See Note 3 to the financial statements of Southern Company and Georgia Power under "Retail Regulatory Matters – Georgia Power – Other Construction" and "Construction – Other Construction," respectively, in Item 8 of the Form 10-K for additional information.

Plant McDonough Unit 1 was retired on February 29, 2012. Georgia Power placed Plant McDonough-Atkinson Unit 5 into service on April 26, 2012 and Plant McDonough-Atkinson Unit 6 was placed into service on October 28, 2012.

Retail Base Rate Case

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Retail Base Rate Case" in Item 8 of the Form 10-K for additional information.

On March 12, 2012, the Florida PSC approved a permanent increase in retail base rates and charges of $64 million effective April 11, 2012. The amount of the permanent increase includes the previously approved $38.5 million interim retail rate increase implemented in September 2011. The Florida PSC's decision on the amount of the permanent increase also included a determination that none of the base rate revenues collected on an interim basis would be refunded. Gulf Power's authorized retail ROE is a range of 9.25% to 11.25% with new retail base rates set at the midpoint retail ROE of 10.25%. In addition, the Florida PSC also approved a step increase to Gulf Power's retail base rates and charges of $4 million to be effective in January 2013.

Cost Recovery Clauses

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Cost Recovery Clauses" in Item 8 of the Form 10-K for additional information.

On November 5, 2012, the Florida PSC approved Gulf Power's annual rate clause requests for its fuel, purchased power capacity, conservation, and environmental compliance cost recovery factors for 2013. The net effect of the approved changes is a 1.9% rate increase for residential customers using 1,000 KWHs per month.

At December 31, 2011, the over recovered purchased power capacity costs totaled $8.0 million, which is included in other regulatory liabilities, current on Gulf Power's Condensed Balance Sheets herein.

Environmental Cost Recovery

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Environmental Cost Recovery" in Item 8 of the Form 10-K for additional information.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a flue gas desulfurization system (scrubber) on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court of Harrison County, Mississippi (Chancery Court). These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, excluding AFUDC, and it is scheduled for completion in December 2015. Gulf Power's portion of the cost is expected to be recovered through the environmental cost recovery clause. The ultimate outcome of this matter cannot be determined at this time.

Over recovered environmental costs at September 30, 2012 totaled $6.9 million compared to $10.0 million at December 31, 2011. These amounts are included in other regulatory liabilities, current on Gulf Power's Condensed Balance Sheets herein.

Energy Conservation Cost Recovery

See Note 3 to the financial statements of Gulf Power under "Retail Regulatory Matters – Energy Conservation Cost Recovery" in Item 8 of the Form 10-K for additional information.

Mississippi Power

Performance Evaluation Plan

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Performance Evaluation Plan" in Item 8 of the Form 10-K for additional information regarding Mississippi Power's base rates.

On April 2, 2012, Mississippi Power filed a motion to suspend the 2011 PEP lookback filing. Unresolved matters related to certain costs included in the 2010 PEP lookback filing also impact the 2011 PEP lookback filing, making it impractical to determine Mississippi Power's actual retail return on investment for 2011 for purposes of the 2011 PEP lookback filing. An order granting the suspension of the 2011 PEP lookback was signed by the Mississippi PSC on May 8, 2012. While Mississippi Power does not expect the resolution of these unresolved matters to have a material impact on its financial statements, the ultimate outcome of these matters cannot be determined at this time.

System Restoration Rider

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – System Restoration Rider" in Item 8 of the Form 10-K for additional information.

On February 2, 2012, Mississippi Power submitted its 2012 System Restoration Rider (SRR) rate filing with the Mississippi PSC, which proposed that the 2012 SRR rate level remain at zero and Mississippi Power be allowed to accrue approximately $3.7 million to the property damage reserve in 2012. On April 3, 2012, the filing was approved by the Mississippi PSC.

Environmental Compliance Overview Plan

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Environmental Compliance Overview Plan" in Item 8 of the Form 10-K for information on Mississippi Power's annual environmental filing with the Mississippi PSC.

On February 14, 2012, Mississippi Power submitted its 2012 ECO Plan filing, which proposed a 0.3% increase in annual revenues for Mississippi Power. In compliance with the CPCN to construct a scrubber on Plant Daniel Units 1 and 2, Mississippi Power revised the 2012 ECO Plan filing to exclude scrubber expenditures from rate base, which resulted in a 0.16% decrease in annual revenues. On June 22, 2012, the 2012 ECO Plan filing, including the proposed rate decrease, was approved by the Mississippi PSC, effective on June 29, 2012.

On April 3, 2012, the Mississippi PSC approved Mississippi Power's request for a CPCN to construct a scrubber on Plant Daniel Units 1 and 2. On May 3, 2012, the Sierra Club filed a notice of appeal of the order with the Chancery Court. These units are jointly owned by Mississippi Power and Gulf Power, with 50% ownership each. The estimated total cost of the project is approximately $660 million, with Mississippi Power's portion being $330 million, excluding AFUDC. The project is scheduled for completion in December 2015. Mississippi Power's portion of the cost is expected to be recovered through the ECO Plan. As of September 30, 2012, total project expenditures were $118.4 million, with Mississippi Power's portion being $59.2 million. The ultimate outcome of this matter cannot be determined at this time.

Certificated New Plant

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "Integrated Coal Gasification Combined Cycle" herein for additional information.

On May 23, 2012, the Mississippi Public Utilities Staff signed a joint stipulation with Mississippi Power to establish a new rate schedule for Certificated New Plant-A (CNP-A), a proposed cost recovery mechanism designed specifically to recover financing costs during the construction phase of the Kemper IGCC. An amended and restated stipulation was subsequently executed and filed on June 1, 2012. On June 14, 2012, Mississippi Power submitted to the Mississippi PSC a proposed supplemental compliance filing to establish the new CNP-A rate schedule and a stipulated rate increase based upon the revenue request of between $55.3 million and $58.6 million to recover financing costs over the remainder of 2012.

On June 22, 2012, the Mississippi PSC denied the proposed CNP-A rate schedule and the 2012 rate recovery filings submitted by Mississippi Power, pending a final ruling from the Mississippi Supreme Court regarding the motion for stay and notice of appeal filed by the Sierra Club on April 26, 2012 relating to the Mississippi PSC's issuance of the CPCN for the Kemper IGCC. On July 9, 2012, Mississippi Power appealed the Mississippi PSC's June 22, 2012 decision to the Mississippi Supreme Court and requested interim rates under bond of $55.3 million. On July 31, 2012, the Mississippi Supreme Court denied Mississippi Power's request for interim rates under bond while the Mississippi Supreme Court decides Mississippi Power's appeal of the Mississippi PSC's June 22, 2012 decision.

On September 13, 2012, the Mississippi PSC filed the record in the appeal of the Mississippi PSC's June 22, 2012 decision with the Mississippi Supreme Court. If the Mississippi Supreme Court does not render a decision within 180 days of the filing of the record, the rates proposed on June 14, 2012 will go into effect, subject to refund by Mississippi Power.

The ultimate outcome of this matter cannot be determined at this time.

Fuel Cost Recovery

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Fuel Cost Recovery" in Item 8 of the Form 10-K for information regarding Mississippi Power's fuel cost recovery.

At September 30, 2012, the amount of over recovered retail fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $52.8 million compared to $42.4 million at December 31, 2011. Mississippi Power also has wholesale MRA and Market Based (MB) fuel cost recovery factors. At September 30, 2012, the amount of over recovered wholesale MRA and MB fuel costs included in Mississippi Power's Condensed Balance Sheets herein was $16.8 million and $2.1 million, respectively, compared to $14.3 million and $2.2 million, respectively, at December 31, 2011. In addition, at September 30, 2012, the amount of under recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $0.2 million. At December 31, 2011, the amount of over recovered MRA emissions allowance cost included in Mississippi Power's Condensed Balance Sheets herein was $1.7 million. Mississippi Power's operating revenues are adjusted for differences in actual recoverable fuel cost and amounts billed in accordance with the currently approved cost recovery rate. Accordingly, any changes in the billing factors will not have a significant effect on Mississippi Power's revenues or net income, but will affect annual cash flow.

Storm Damage Cost Recovery

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Storm Damage Cost Recovery" in Item 8 in the Form 10-K for information regarding Mississippi Power's storm damage cost recovery. In August 2012, Hurricane Isaac hit the Gulf Coast of the United States and caused damage within Mississippi Power's service area. The estimated total storm restoration costs relating to Hurricane Isaac through September 30, 2012 were $9.7 million. Mississippi Power maintains a reserve to cover the cost of damage from major storms to its transmission and distribution facilities and generally the cost of uninsured damage to its generation facilities and other property. At September 30, 2012, the balance in the storm reserve was $58.7 million.

Integrated Coal Gasification Combined Cycle

See Note 3 to the financial statements of Southern Company and Mississippi Power under "Integrated Coal Gasification Combined Cycle" in Item 8 of the Form 10-K for information regarding Mississippi Power's construction of the Kemper IGCC.

In May 2010, Mississippi Power filed a motion with the Mississippi PSC accepting the conditions contained in the Mississippi PSC order confirming Mississippi Power's application for a CPCN authorizing the acquisition, construction, and operation of the Kemper IGCC. In June 2010, the Mississippi PSC issued the CPCN (2010 MPSC Order).

In June 2010, the Sierra Club filed an appeal of the Mississippi PSC's June 2010 decision to grant the CPCN for the Kemper IGCC with the Chancery Court. Subsequently, in July 2010, the Sierra Club also filed an appeal directly with the Mississippi Supreme Court. In October 2010, the Mississippi Supreme Court dismissed the Sierra Club's direct appeal. In February 2011, the Chancery Court issued a judgment affirming the 2010 MPSC Order and, in March 2011, the Sierra Club appealed the Chancery Court's decision to the Mississippi Supreme Court. On March 15, 2012, the Mississippi Supreme Court reversed the Chancery Court's decision and the 2010 MPSC Order and remanded the matter to the Mississippi PSC to correct the 2010 MPSC Order. The Mississippi Supreme Court concluded that the 2010 MPSC Order did not cite in sufficient detail substantial evidence upon which the Mississippi Supreme Court could determine the basis for the findings of the Mississippi PSC granting the CPCN.

On March 30, 2012, the Mississippi PSC issued temporary authorization for the continuation of construction of the Kemper IGCC. On April 24, 2012, the Mississippi PSC issued a detailed order on remand (2012 MPSC Order) confirming the CPCN for the Kemper IGCC subject to the same conditions set forth in the 2010 MPSC Order. On April 26, 2012, the Sierra Club filed a motion for stay and a notice of appeal of the 2012 MPSC Order with the Chancery Court. On May 18, 2012, Mississippi Power's motion to join the appeal was approved. On August 7, 2012, the Sierra Club withdrew its motion for stay.

The certificated cost estimate of the Kemper IGCC is $2.4 billion, net of $245.3 million of grants awarded to the project by the DOE under the Clean Coal Power Initiative Round 2 (CCPI2) and excluding the cost of the lignite mine and equipment and the carbon dioxide (CO₂) pipeline facilities. The 2012 MPSC Order, like the 2010 MPSC Order, (1) approved a construction cost cap of up to $2.88 billion (exemptions from the cost cap include the cost of the lignite mine and equipment, the CO₂ pipeline facilities, AFUDC, and certain general exceptions, including change of law, force majeure, and beneficial capital, which exists when Mississippi Power demonstrates that the purpose and effect of the construction cost increase is to produce efficiencies that will result in a neutral or favorable effect on the ratepayers, relative to the original proposal), (2) provided for the establishment of operational cost and revenue parameters based upon assumptions in Mississippi Power's proposal, and (3) approved financing cost recovery on CWIP balances not to exceed the certificated cost estimate, which provided for the accrual of AFUDC in 2010 and 2011 and provides for the current recovery of financing costs on 100% of CWIP in 2012, 2013, and through May 1, 2014 (provided that the amount of CWIP allowed is (i) reduced by the amount of state and federal government construction cost incentives received by Mississippi Power in excess of $296 million to the extent that such amount increases cash flow for the pertinent regulatory period and (ii) justified by a showing that such CWIP allowance will benefit customers over the life of the Kemper IGCC).

Mississippi Power's current cost estimate for the Kemper IGCC equals the $2.88 billion cost cap, including a $40 million to $50 million contingency. The Mississippi PSC and the Mississippi Public Utilities Staff have engaged their independent monitors to assess the current cost estimates and schedule projections for the Kemper IGCC. These consultants are issuing reports with their own opinions as to the likelihood that costs for the Kemper IGCC will remain under the $2.88 billion cost cap and as to the expected in-service date. While Mississippi Power continues to believe its cost estimate and schedule projection remain appropriate based on the current status of the project, it is possible that Mississippi Power will experience further cost increases and/or schedule delays with respect to the Kemper IGCC. Certain factors have caused and may continue to cause the costs for the Kemper IGCC to increase and/or schedule delays to occur including, but not limited to, costs and productivity of labor, adverse weather conditions, shortages and inconsistent quality of equipment, materials and labor, contractor or supplier delay or non-performance under construction or other agreements, and unforeseen engineering problems. To the extent that costs beyond any permitted exceptions to the cost cap exceed $2.88 billion or the Mississippi PSC disallows a portion of the costs relating to the Kemper IGCC, including financing costs, charges to expense may occur and these charges could be material.

The Kemper IGCC, expected to be in service in May 2014, will use locally mined lignite (an abundant, lower heating value coal) from a mine adjacent to the Kemper IGCC as fuel. The mine is scheduled to be placed into service in June 2013. In conjunction with the Kemper IGCC, Mississippi Power will own the lignite mine and equipment and has acquired and will continue to acquire mineral reserves located around the Kemper IGCC site in Kemper County. The estimated capital cost of the mine is approximately $245 million, of which $127 million has been incurred through September 30, 2012.

In May 2010, Mississippi Power executed a 40-year management fee contract with Liberty Fuels Company, LLC, a wholly-owned subsidiary of The North American Coal Corporation (Liberty Fuels), which will develop, construct, and manage the mining operations. Because Liberty Fuels conducts all of its activities on behalf of Mississippi Power, Liberty Fuels qualifies as a variable interest entity for which Mississippi Power is the primary beneficiary. The contract with Liberty Fuels is effective through the end of the mine reclamation. As the mining permit holder, Liberty Fuels has a legal obligation to perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities. Consistent with the requirements of consolidation accounting, Liberty Fuels is consolidated in the financial statements of Mississippi Power and accordingly the asset retirement cost and the ARO have been recorded in Mississippi Power's financial statements. In addition to the obligation to fund the reclamation activities, Mississippi Power currently provides working capital support to Liberty Fuels through cash advances for capital purchases, payroll, and other operating expenses.

In December 2011, the Mississippi Department of Environmental Quality (MDEQ) approved the surface coal mining and the water pollution control permits for the mining operations operated by Liberty Fuels. On January 12, 2012, two individuals each filed a notice of appeal and a request for evidentiary hearing with the MDEQ regarding the surface coal mining and water pollution control permits. On March 8, 2012, the MDEQ permit board affirmed its issuance of the surface coal mining and water pollution control permits.

In 2009, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $133 million of Internal Revenue Code Section 48A tax credits (Phase I) to Mississippi Power. In April 2011, Mississippi Power received notification from the IRS formally certifying that the IRS allocated $279 million of Internal Revenue Code Section 48A tax credits (Phase II) to Mississippi Power. The utilization of Phase I and Phase II credits is dependent upon meeting the IRS certification requirements, including an in-service date no later than May 11, 2014 for the Phase I credits and April 19, 2016 for the Phase II credits. In order to remain eligible for the Phase II credits, Mississippi Power plans to capture and sequester (via enhanced oil recovery) at least 65% of the CO₂ produced by the Kemper IGCC during operations in accordance with the rules for Section 48A investment tax credits. Through September 30, 2012, Mississippi Power received or accrued tax benefits totaling $276.8 million for these tax credits, which will be amortized as a reduction to depreciation and amortization over the life of the Kemper IGCC. On October 15, 2012, Mississippi Power filed an application with the DOE for certification of the Kemper IGCC for additional tax credits under the Internal Revenue Code Section 48A (Phase III). A portion of the tax credits realized by Mississippi Power may be subject to recapture upon successful completion of SMEPA's

purchase of undivided interest in the Kemper IGCC. Based on current tax laws and regulations in effect, Mississippi Power expects to receive substantially all of the tax credits accrued through September 30, 2012 by September 30, 2013.

In July 2010, Mississippi Power and SMEPA entered into an asset purchase agreement whereby SMEPA agreed to purchase a 17.5% undivided interest in the Kemper IGCC. In December 2010, Mississippi Power and SMEPA filed a joint petition with the Mississippi PSC requesting regulatory approval of SMEPA's 17.5% undivided interest in the Kemper IGCC. On February 28, 2012, the Mississippi PSC approved the joint petition for the sale and transfer of 17.5% of the Kemper IGCC to SMEPA. On June 29, 2012, Mississippi Power and SMEPA signed an amendment to the asset purchase agreement whereby SMEPA extended its option to purchase until December 31, 2012 and reduced its purchase commitment percentage from a 17.5% to a 15% undivided interest in the Kemper IGCC, subject to approval by the Mississippi PSC. The closing of this transaction is conditioned upon execution of a joint ownership and operating agreement, receipt of all construction permits, appropriate regulatory approvals, financing, and other conditions. On September 27, 2012, SMEPA received a conditional loan commitment from Rural Utilities Service to provide funding for SMEPA's undivided interest in the Kemper IGCC.

On March 6, 2012, Mississippi Power received a $150 million interest-bearing refundable deposit from SMEPA to be applied to the purchase. While the expectation is that the amount will be applied to the purchase price at closing, Mississippi Power would be required to refund the deposit upon the termination of the asset purchase agreement, within 60 days of a request by SMEPA for a full or partial refund, or within 15 days at SMEPA's discretion in the event that Mississippi Power is assigned a senior unsecured credit rating of BBB+ or lower by S&P or Baa1 or lower by Moody's or ceases to be rated by either of these rating agencies. Given the interest-bearing nature of the deposit and SMEPA's ability to request a refund, the deposit has been presented as a current liability in Mississippi Power's Condensed Balance Sheet herein and as financing proceeds in Mississippi Power's Condensed Statement of Cash Flows herein.

As of September 30, 2012, Mississippi Power had spent a total of $2.1 billion on the Kemper IGCC including the cost of the lignite mine and equipment, the CO₂ pipeline facilities, and regulatory filing costs. Of this total, $2.0 billion was included in CWIP (which is net of $245.3 million of CCPI2 grant funds), $30.2 million was recorded in other regulatory assets, $3.0 million was recorded in other deferred charges and assets, and $1.0 million was previously expensed.

The Mississippi PSC order established periodic prudence reviews during the annual CWIP review process. Of the total costs of $51 million incurred through March 2009, $46 million has been reviewed and deemed prudent by the Mississippi PSC in the 2010 MPSC Order and again in the 2012 MPSC Order. A decision regarding the remaining $5 million has not been issued. The timing of the review of the remaining Kemper IGCC costs has not been determined.

See Note 3 to the financial statements of Mississippi Power under "Retail Regulatory Matters – Certificated New Plant" in Item 8 of the Form 10-K and "Retail Regulatory Matters – Certificated New Plant" herein for information on the proposed rate schedules related to the Kemper IGCC.

The ultimate outcome of these matters cannot be determined at this time.
