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, 2012 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, 2013 and 2012. 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 (with respect to Southern Company, Alabama Power, Georgia Power, Gulf Power, and Southern Power) and the Form 10-K/A (with respect to Mississippi Power) and details which have not changed significantly in amount or composition since the filings of the Form 10-K or the Form 10-K/A, as applicable, are generally omitted from this Quarterly Report on Form 10-Q unless specifically required by GAAP. Therefore, these Condensed Financial Statements should be read in conjunction with the financial statements and the notes thereto included in the Form 10-K (with respect to Southern Company, Alabama Power, Georgia Power, Gulf Power, and Southern Power) and the Form 10-K/A (with respect to Mississippi Power). 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. These reclassifications had no impact on the results of operations, financial position, or cash flows of any registrant.
Nuclear Decommissioning
See Note 1 to the financial statements of Southern Company and Alabama Power under "Nuclear Decommissioning" in Item 8 of the Form 10-K for additional information.
In September 2013, Alabama Power received a 2013 decommissioning cost site study for Plant Farley. Site study cost is the estimate to decommission a facility as of the site study year. The estimated costs of decommissioning based on the 2013 site study are as follows:
Decommissioning periods:
 
Beginning year
2037
Completion year
2076
 
(in millions)
Site study costs:
 
Radiated structures
$
1,362

Non-radiated structures
80

Total site study costs
$
1,442


The decommissioning cost estimates are based on prompt dismantlement and removal of the plant from service. The actual decommissioning costs may vary from the above estimates due to changes in the assumed date of decommissioning, changes in NRC requirements, or changes in the assumptions used in making these estimates.
For ratemaking purposes, Alabama Power's decommissioning costs are based on the site study. Significant assumptions used to determine these costs for ratemaking were an escalation rate of 4.5% and a trust earnings rate of 7.0%, net of fees and taxes. The next site study is expected to be conducted in 2018.
Amounts previously contributed to the external trust funds are currently projected to be adequate to meet the decommissioning obligations. Alabama Power will continue to provide site specific estimates of the decommissioning costs and related projections of funds in the external trust to the Alabama PSC and, if necessary, would seek the Alabama PSC's approval to address any changes in a manner consistent with the NRC and other applicable requirements.
Asset Retirement Obligations
See Note 1 to the financial statements of Southern Company and Alabama Power under "Asset Retirement Obligations and Other Costs of Removal" in Item 8 of the Form 10-K for additional information.
Asset retirement obligations (ARO) are computed as the present value of the ultimate costs for an asset's future retirement and are recorded in the period in which the liability is incurred. In September 2013, Alabama Power received a new ARO liability cost study for the decommissioning of Plant Farley based on the 2013 site study, which increased the estimated ARO liability by approximately $102 million.
As of September 30, 2013 and 2012, details of the ARO related to the decommissioning of Plant Farley included in Southern Company's and Alabama Power's Condensed Balance Sheets herein are as follows:
