PART I. FINANCIAL INFORMATION.

Filing Format

This combined Form 10-Q is being filed separately by MGE Energy, Inc. (MGE Energy) and Madison Gas and Electric Company (MGE). MGE is a wholly owned subsidiary of MGE Energy and represents a substantial portion of its assets, liabilities, revenues, expenses, and operations. Thus, all information contained in this report relates to, and is filed by, MGE Energy. Information that is specifically identified in this report as relating solely to MGE Energy, such as its financial statements and information relating to its nonregulated business, does not relate to, and is not filed by, MGE. MGE makes no representation as to that information. The terms "we" and "our" as used in this report refer to MGE Energy and its consolidated subsidiaries, unless otherwise indicated.

Forward-Looking Statements

This report, and other documents filed by MGE Energy and MGE with the Securities and Exchange Commission (SEC) from time to time, contain forward-looking statements that reflect management's current assumptions and estimates regarding future performance and economic conditions--especially as they relate to future load growth, revenues, expenses, capital expenditures, financial resources, regulatory matters, and the scope and expense associated with future environmental regulation. These forward-looking statements are made pursuant to the provisions of the Private Securities Litigation Reform Act of 1995. Words such as "believe," "expect," "anticipate," "estimate," "could," "should," "intend," and other similar words generally identify forward-looking statements. Both MGE Energy and MGE caution investors that these forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual results to differ materially from those projected, expressed, or implied. Some of those risks and uncertainties include:

- Weather, which enters into the calculation of MGE's rates for service and which affects the demand for electricity and gas and the projected and actual need for electric generation capacity to serve customers.

- Economic and market conditions in MGE's service territory, which affect demand for electricity and gas and, consequently, our revenues and expenses as well as capital investment requirements to extend, improve, or reinforce the existing electricity and gas distribution systems.

- Magnitude and timing of capital expenditures, which affect capital needs, financing costs, and operating expenses.

- Regulatory environment in which we operate, which can affect the way in which we do business as well as the accounting treatment of expenses that we incur and our ability to continue carrying specified assets and liabilities on our books.

- Environmental regulation, which can affect the way in which we operate, our operating expenses, and our capital expenditures.

- Availability and cost of power supplies, which affect operating expenses and capital expenditure decisions with respect to sources of new generation.

Readers are cautioned not to place undue reliance on these forward-looking statements, which apply only as of the date of this report. MGE Energy and MGE undertake no obligation to publicly release any revision to these forward-looking statements to reflect events or circumstances after the date of this report.

MGE Energy, Inc., and Madison Gas and Electric Company Notes to Condensed Consolidated Financial Statements (unaudited)
June 30, 2005

1. Basis of Presentation - MGE Energy and MGE.

This report is a combined report of MGE Energy and MGE. References in this report to "MGE Energy" are to MGE Energy, Inc., and its subsidiaries. References in this report to "MGE" are to Madison Gas and Electric Company.

The accompanying condensed consolidated financial statements as of June 30, 2005, and for the three and six months then ended, are unaudited, but include all adjustments that MGE Energy and MGE management consider necessary for a fair statement of their respective financial statements. All adjustments are of a normal, recurring nature except as otherwise disclosed. The year-end consolidated balance sheet information was derived from the audited balance sheet appearing in MGE Energy's and MGE's annual reports on Form 10-K for the year ended December 31, 2004, but does not include all disclosures required by generally accepted accounting principles. These notes should be read in conjunction with the financial statements and the notes on pages 56 through 89 of the 2004 Form 10-K. Certain amounts in prior periods' financial statements and related notes have been reclassified to conform to the 2005 presentation.

2. Basis of Consolidation - MGE Energy and MGE.

MGE Power West Campus is not a subsidiary of MGE; however, it has been consolidated in the financial statements of MGE as of December 31, 2003, and subsequent periods due to the adoption of FIN 46R (see Footnote 9). MGE Power West Campus was created for the purpose of owning new generating assets including WCCF. These new generating assets are for the primary benefit of MGE's customers. The long-term lease arrangement between MGE and MGE Power West Campus creates a VIE relationship under FIN 46R. MGE is considered the primary beneficiary of this VIE because it will absorb a majority of the entity's expected losses, residual returns, or both.

The consolidation of MGE Power West Campus into MGE resulted in a significant increase to certain balance sheet accounts as shown in the following table:

(In thousands)	June 30, 2005	December 31, 2004
Nonutility plant	$106,509	-
Construction work in progress	-	$95,672
Cash	$1,317	$538
Long-term debt	$30,000	$30,000
Asset retirement obligation	$988	-
Minority interest (a)	$46,168	$40,377
Affiliate receivable (a)	$4,504	-
Affiliate payables (a)	$19,562	$19,350
(a) Amounts are eliminated in the MGE Energy consolidated financial statements.

On April 26, 2005, MGE began operation of its electric facility. Additionally, on April 26, 2005, the lease between MGE and MGE Power West Campus commenced. In accordance with the provisions of SFAS No. 13, Accounting for Leases, MGE, as the lessee, accounts for the aforementioned lease arrangement as a capital lease and MGE Power West Campus, as the lessor, accounts for the lease as a direct financing leasing arrangement prior to consolidation or on their individual general ledgers prior to consolidation.

3. Rate Matters - MGE Energy and MGE.

a. Rate proceedings.

On April 19, 2005, MGE filed an application with the PSCW to increase electric rates 5.19% and natural gas rates by 1.4% for 2006. These increases are intended to cover the costs of additional facilities needed to meet the rising electric and gas needs of our customers.

On December 21, 2004, the PSCW authorized MGE to increase 2005 electric revenues by $27.4 million and to decrease 2005 gas revenues by $4.2 million. The increase to electric revenues is intended to cover rising fuel costs, commercial operation of WCCF, and increased transmission expenses.

On January 14, 2004, the PSCW authorized MGE to increase 2004 gas and electric revenues by $12.8 million. The increase covered rising fuel costs for electric generation and addressed increased system demands.

b. Fuel Rules.

Actual electric fuel costs are subject to reconciliation to the amounts approved by the PSCW in MGE's rate order covering the applicable period. The reconciliation process can produce a fuel surcharge for MGE or require MGE to make a refund in the form of a credit, to the extent that the actual fuel costs are outside a 3.0% range higher or lower than the level authorized by the PSCW.

On April 18, 2005, the PSCW decided to reopen MGE's current rate order docket to commence a limited scope proceeding under the fuel rules to determine if a fuel credit is required for 2005. If a determination is made by the PSCW in this proceeding that a fuel credit is required, the time period for determining the credit begins on April 18, 2005. MGE is unable to estimate the future financial impact of these proceedings at this time. As of June 30, 2005, MGE was not outside of the 3.0% annual range and, therefore, no amounts have been accrued for a fuel rules credit as of June 30, 2005.

On August 10, 2004, the PSCW reopened MGE's rate docket for the limited purposes of determining whether a fuel credit was due for 2004 under the fuel rules. On September 30, 2004, MGE filed an application to decrease electric rates for 2004 by $0.0025 per kWh, reflecting its view of the credit due customers under the fuel rules. This amount was subsequently revised to $0.00275 per kWh. Based upon these filings, MGE recorded a reduction in electric revenues to reflect the fuel rules refund in the amount of $3.4 million for 2004, of which $1.8 million was refunded on customers' bills during 2004 and $1.6 million was refunded to customers in January 2005.

During 2003, MGE submitted an application for a fuel cost credit. On August 14, 2003, the PSCW approved an interim fuel credit of $0.00099 per kWh and also required a full review of the actual and forecasted costs for 2003, with MGE's fuel rates subject to refund. The fuel credit began in August 14, 2003, and ended on January 13, 2004. The fuel credit totaled $4.4 million, of which $1.2 million represents the interim fuel credit and $3.2 million is the additional fuel credit that resulted from PSCW review and was credited to customers in the first quarter of 2004. Of the $3.2 million in additional fuel credit, $0.4 million was refunded from January 1 through January 13, 2004.

4. Equity - MGE Energy.

a. Common Stock.

On August 15, 2003, MGE Energy entered into a Distribution Agreement (Agreement) with BOCM. Under the terms of this Agreement, MGE Energy may periodically offer and sell up to 1,600,000 shares of its common stock through BOCM as its sales agent or to BOCM as principal. The sales will be made pursuant to a shelf registration statement MGE Energy filed with the SEC.

MGE Energy did not sell any shares of common stock under the Agreement during the three and six months ended June 30, 2005. During the three and six months ended June 30, 2004, MGE Energy sold 44,000 and 124,000 shares, respectively, of its common stock. The sales resulted in net proceeds of $1.3 million and $3.8 million for the three and six months ended June 30, 2004.

MGE Energy also issues new shares of its common stock through the Stock Plan. For the six months ended June 30, 2005, MGE Energy issued 65,000 new shares of common stock under the Stock Plan for net proceeds of $2.3 million. No new shares were issued during the three months ended June 30, 2005. For the three and six months ended June 30, 2004, MGE Energy issued 181,000 and 326,000 new shares of common stock under the Stock Plan for net proceeds of $5.5 million and $10.0 million, respectively.

In March 2005, MGE Energy switched from issuing new shares of common stock for the Stock Plan to purchasing shares on the open market through a securities broker-dealer on behalf of the plan participants. At June 30, 2005, MGE Energy held $0.3 million of treasury stock that had been purchased on the open market and are intended to be re-issued under the Stock Plan. The cost basis of these shares is shown as a reduction to stockholders' equity on the MGE Energy condensed consolidated financial statements.

b. Preferred Stock - MGE Energy and MGE.

MGE has 1,175,000 shares of $25 par value redeemable preferred stock (cumulative) that is authorized but unissued at June 30, 2005.

c. Dilutive Shares Calculation - MGE Energy.

MGE Energy does not hold any dilutive securities.

d. Accumulated Other Comprehensive Income - MGE Energy and MGE.

The accumulated other comprehensive income balance at June 30, 2005, includes the unrealized gains and losses on available-for-sale securities. The following table illustrates the changes in Accumulated Other Comprehensive Income, net of taxes, from December 31, 2004, to June 30, 2005, for MGE Energy and MGE:

(In thousands)	MGE Energy	MGE
Balance, December 31, 2004	$ 686	$ 63
Decrease in unrealized gain on available for sale securities, net of tax benefit of $289 and $47, respectively	(431)	(70)
Balance, June 30, 2005	$ 255	$ (7)

5. Minority Interest - MGE.

MGE Power West Campus is not a subsidiary of MGE; however, it has been consolidated in the consolidated financial statements of MGE as of June 30, 2005 and 2004, due to the adoption of FIN 46R (see Footnote 9).

MGE Power West Campus is owned indirectly by MGE Energy. MGE Energy's proportionate share of the equity and net income (through its wholly owned subsidiary MGE Power) of MGE Power West Campus is classified within the MGE financial statements as minority interest. As of June 30, 2005 and 2004, MGE Energy (through its wholly owned subsidiary MGE Power) had invested $44.8 and $26.8 million, respectively, in MGE Power West Campus. For the six months ended June 30, 2005, MGE Energy (through its wholly owned subsidiary MGE Power) had earned $1.4 million, net of tax, from its interest in MGE Power West Campus. This amount is recorded as minority interest expense, net of tax, on MGE's consolidated statement of income.

6. Comprehensive Income - MGE Energy and MGE.

The reporting of other comprehensive income is required under the provisions of SFAS No. 130, Reporting Comprehensive Income. Total comprehensive income represents the change in equity during a period from transactions and other events and circumstances from nonowner sources. MGE Energy's and MGE's total comprehensive income are:

(In thousands)	Three Months Ended June 30,		Six Months Ended June 30,
MGE Energy	2005	2004	2005	2004
Net Income	$5,442	$5,827	$13,657	$19,618
Other comprehensive income	(154)	248	(431)	248
Total Comprehensive Income	$5,288	$6,075	$13,226	$19,866
MGE
Net Income	$3,814	$5,470	11,666	$18,552
Other comprehensive income	(27)	-	(70)	-
Total Comprehensive Income	$3,787	$5,470	$11,596	$18,552

7. Property, Plant, and Equipment - MGE Energy and MGE.

a. Capitalized interest.

MGE Energy, through its subsidiary MGE Power West Campus, calculates capitalized interest in accordance with SFAS No. 34, Capitalization of Interest Cost, on construction projects for periods where financing is provided by MGE Energy through interim debt. The interest rate capitalized is based upon the monthly short-term borrowing rate MGE Energy incurs for such funds and the interest rate related to MGE Power West Campus' long-term debt. For the six months ended June 30, 2005 and 2004, MGE Energy recorded $0.7 million and $1.1 million, respectively, in capitalized interest related to the cogeneration facility being constructed on the west campus of the UW. On April 26, 2005, when the electric facility began generating electricity, MGE Power West Campus discontinued the capitalization of interest, as the project was deemed to be substantially complete. The total interest capitalized in conjunction with this project is $4.1 million. This amount is included in the property, plant, and equipment balance at June 30, 2005.

b. Asset retirement obligations.

MGE and MGE Energy account for asset retirement obligations in accordance with SFAS No. 143, Accounting for Asset Retirement Obligations. SFAS No. 143 provides accounting requirements for retirement obligations associated with tangible long-lived assets. Retirement obligations associated with long-lived assets included within the scope of SFAS No. 143 are those for which there is a legal obligation under existing or enacted law, statute, written or oral contract, or by legal construction under the doctrine of promissory estoppel.

In April 2005, MGE Power West Campus recorded an obligation for the fair value of its legal liability for asset retirement obligations associated with the demolition and removal of the electric portion of the WCCF facility. Provisions for these demolition and removal costs are included in the facility lease agreement. At June 30, 2005, this liability is estimated at $1.0 million and is included in other deferred liabilities.

Additionally, effective January 1, 2003, MGE recorded an obligation for the fair value of its legal liability for asset retirement obligations associated with removing an electric substation, a combustion turbine generating unit, wind generating facilities, and photovoltaic generating facilities, all of which are located on property not owned by MGE. At June 30, 2005, this portion of the liability is estimated at $1.5 million and included in other deferred liabilities.

The following table shows costs as of December 31, 2003 and December 31, 2004, and changes to the asset retirement obligation and accumulated depreciation through June 30, 2005.

(In thousands)	(a) Original Asset Retirement Obligation	(b) Accumulated Accretion	(c) (a + b) Asset Retirement Obligation	(d) Accumulated Depreciation- Related Asset
Balance December 31, 2003	$ 686	$675	$1,361	$175
Changes through December 31, 2004	27	86	113	29
Balance, December 31, 2004	$ 713	$761	$1,474	$204
Changes through June 30, 2005	988	46	1,034	15
Balance, June 30, 2005	$1,701	$807	$2,508	$219

MGE has a regulatory asset for the total accumulated accretion and total accumulated depreciation related to its asset retirement obligation. MGE expects to recover this regulatory asset through rates charged to customers.

Accumulated previous collections of costs of removal that are non-SFAS No. 143 obligations are classified within the financial statements as regulatory liabilities. At June 30, 2005, and December 31, 2004, there were $18.0 million and $17.7 million, respectively, of these costs recorded as regulatory liabilities within the financial statements.

8. Pension and Postretirement Plans - MGE Energy and MGE.

MGE maintains qualified and nonqualified pension plans. MGE also provides health care and life insurance benefits for its retired employees. MGE has elected to recognize the cost of its transition obligation (the accumulated postretirement benefit obligation as of January 1, 1993) by amortizing it on a straight-line basis over 20 years.

a. Net Periodic Cost.

The following tables present the components of MGE's net periodic benefit costs recognized for the three and six months ended June 30, 2005 and 2004. A portion of the net periodic benefit cost is capitalized within the Condensed Consolidated Balance Sheets.

	Pension Benefits
	Three Months Ended June 30,		Six Months Ended June 30,
(In thousands)	2005	2004	2005	2004
Components of net periodic benefit cost:
Service cost	$ 944	$ 678	$1,977	$1,942
Interest cost	1,754	1,438	3,671	4,118

Interest cost	662	684	1,369	1,483
Expected return on assets	(210)	(182)	(434)	(391)
Amortization of:
Transition obligation	92	93	190	200
Prior service cost	47	41	98	87
Actuarial gain	156	200	323	441
Net periodic benefit cost	$1,177	$1,246	$2,435	$2,708

During the third quarter of 2004, MGE adopted the provisions of FSP 106-2, resulting in a remeasurement of its postretirement benefit plans' assets and APBO as of January 1, 2004. The effect of the subsidy on benefits attributable to past service was accounted for as an actuarial experience gain, resulting in a decrease in the APBO of $4.3 million. The annualized reduction in the net periodic postretirement benefit cost is estimated to be $0.7 million compared to the annual cost calculated without considering the effects of the Prescription Drug Act.

Previously reported financial information for the three and six months ended June 30, 2004, has been adjusted to reflect a reduction in net periodic postretirement benefit cost as if FSP 106-2 was adopted as of January 1, 2004. Amounts for these periods have been presented as such for comparative purposes. The following table presents MGE's net income and MGE Energy's net income and earnings per share for the three and six months ended June 30, 2004, as if FSP 106-2 was adopted as of January 1, 2004.

	Three Months Ended June 30, 2004		Six Months Ended June 30, 2004
(In thousands except per share amounts)	MGE Energy	MGE	MGE Energy	MGE
Net Income-as previously reported	$5,680	$5,323	$19,324	$18,258
Reduction in net periodic cost	147	147	294	294
Adjusted net income	$5,827	$5,470	$19,618	$18,552
Earnings per share-as previously reported	$0.30	NA	$1.04	NA
Earnings per share-as adjusted	$0.31	NA	$1.06	NA

b. Expected Cash Flows.

There were no required contributions for 2004. Additionally, there are no required contributions for 2005; however, MGE may elect to make discretionary deductible contributions depending upon its valuation results and cash flow from operations. MGE made a $4 million contribution during the six months ended June 30, 2005, related to the 2004 plan year. MGE expects to make a $3 million discretionary contribution in the first quarter of 2006, for the 2005 plan year. This contribution is solely at MGE's discretion and is not required by law or regulation.

9. Adoption of Accounting Principles and Recently Issued Accounting Pronouncements - MGE Energy and MGE.

a. FIN 46R.

In January 2003, the FASB issued FIN 46, Consolidation of Variable Interest Entities - An Interpretation of ARB No. 51. In December 2003, the FASB issued the updated and final interpretation FIN 46R. FIN 46R requires that an equity investor in a VIE have significant equity at risk (generally a minimum of 10%, which is an increase from 3% required under the previous guidance) and hold a controlling interest, evidenced by voting rights, and absorb a majority of the entity's expected losses, receive a majority of the entity's expected returns, or both. If the equity investor is unable to evidence these characteristics, the entity that retains these ownership characteristics will be required to consolidate the VIE as the primary beneficiary. FIN 46 was applicable immediately to VIEs created or obtained after January 31, 2003. FIN 46R was effective on December 31, 2003, for interests in entities that were previously considered special purpose entities under then existing authoritative guidance.

MGE Power West Campus is a VIE pursuant to FIN 46R, as the equity investment at December 31, 2003, was not sufficient to permit the entity to finance its activities without additional support. MGE concluded a VIE relationship exists due to the long-term lease arrangement between MGE and MGE Power West Campus. MGE Power West Campus will lease a major portion of its assets, a power plant, to MGE, pursuant to this leasing arrangement and MGE will absorb a majority of the expected losses, residual, or both. The VIE was consolidated into MGE as of December 31, 2003.

FIN 46R also requires MGE to assess whether the participants within its Shared Savings program constitute VIEs in which MGE might be considered to be the consolidating entity. As of June 30, 2005, MGE has reviewed 81% of the total current Shared Savings program balance and has determined that the provisions of FIN 46R are not applicable via the "business scope exception." For the remaining 19% of the total current Shared Savings program balance, MGE has not performed this assessment. These entities are not legally obligated to provide the financial information to MGE that is necessary to determine whether MGE must consolidate these entities. MGE will continue to attempt to obtain information from these customers in order to determine whether they should be consolidated by MGE.

b. FIN 47.

In March 2005, the FASB issued FIN 47, Accounting for Conditional Asset Retirement Obligations an Interpretation of FASB Statement No. 143. This Interpretation clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability's fair value can be reasonably estimated. Additionally, this Interpretation clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. FIN 47 is effective no later than the 2005 calendar year for calendar-year enterprises. Accordingly, MGE expects to adopt FIN 47 on December 31, 2005. MGE is currently reviewing this statement to determine its effect on its financial statements.

c. FSP 106-2.

On December 8, 2003, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 was signed into law authorizing Medicare to provide prescription drug benefits to retirees. FSP 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003, was issued on May 19, 2004. The FSP provides guidance on the accounting for the effects of the new Medicare prescription drug legislation by employers whose prescription drug benefits are actuarially equivalent to the drug benefit under Medicare Part D. MGE applied the provisions of this guidance in the third quarter of 2004. At that time, previously reported financial information for the three and six months ended June 30, 2004, were adjusted to reflect a reduction in net periodic postretirement benefit cost as if FSP 106-2 was adopted as of January 1, 2004. Amounts for these periods, when presented for comparative purposes, will be presented as such. See Footnote 8 for additional information.

d. FSP 109-1.

In December 2004, the FASB issued FSP 109-1, Application of FASB Statement No. 109, 'Application for Income Taxes,' to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004. The American Jobs Creation Act of 2004 (Act), signed into law on October 22, 2004, provided, generally, for a tax deduction effective for taxable years beginning after December 31, 2004, for domestic manufacturing activities of up to 9% (when fully phased-in) of the lesser of "qualified production activities income," as defined in the Act, or taxable income. FSP 109-1 clarified that the tax deduction for domestic manufacturing activities under the Act should be accounted for as a special deduction in accordance with SFAS No. 109, Accounting for Income Taxes. MGE estimates its tax deduction for 2005 to be $0.2 million. The benefit of this deduction will be passed on to ratepayers and will be recognized ratably throughout the year as a regulatory liability on the financial statements of both MGE Energy and MGE. As of June 30, 2005, MGE had recorded $0.1 million of this deduction as a regulatory liability.

e. EITF 03-01.

In March 2004, the EITF reached a consensus on, and the FASB ratified, EITF issue No. 03-01, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments. EITF 03-01 provides guidance for evaluating whether an investment is other-than-temporarily impaired. MGE and MGE Energy adopted the disclosure requirements of EITF 03-01 for investments accounted for under SFAS No. 115 for the six months ended June 30, 2005.

On September 30, 2004, the FASB issued EITF 03-01-01, Effective Date of Paragraphs 10-20 of EITF Issue No. 03-01, 'The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments, which delayed the effective date of the application guidance reconsidering the conclusions reached within EITF 03-01.

The FASB, at its June 29, 2005, Board meeting, withdrew its guidance on when an impairment is other than temporary. However, EITF 03-01's provisions regarding the measurement, disclosure, and post-impairment accounting guidance of debt securities, as well as the identification of impaired cost method investments remain intact. The FASB expects to issue a final FASB Staff Position in the third-quarter of 2005. Additionally, the existing guidance under SFAS No. 115 remains in effect.

f. SFAS No. 154.

In May 2005, the FASB issued SFAS No. 154, Accounting for Changes and Error Corrections, a replacement of APB (Accounting Principles Board) Opinion No. 20 and SFAS No. 3. Previously, APB Opinion No. 20, Accounting Changes, and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements, required the inclusion of the cumulative effect of changes in accounting principle in net income of the period of the change. SFAS No. 154 requires companies to recognize a change in accounting principle, including a change required by a new accounting pronouncement when the pronouncement does not include specific transition provisions, retrospectively to prior periods' financial statements. MGE and MGE Energy will assess the impact of a retrospective application of any change in accounting principle in accordance with SFAS No. 154 when such a change arises after the effective date of January 1, 2006.

10. West Campus Cogeneration Facility - MGE Energy and MGE.

a. Construction of the facility.

MGE Energy, through MGE Power, MGE Power West Campus, and MGE Construct, is building a natural gas-fired cogeneration facility on the UW campus. The facility has a capacity to produce 20,000 tons of chilled water, 500,000 pounds per hour of steam, and approximately 150 MW of electricity. The UW and MGE Power West Campus jointly own the facility. The UW owns a controlling interest in the chilled-water and steam plants, which will be used to meet the growing needs for air-conditioning and steam-heat capacity for the UW campus. MGE Power West Campus owns a controlling interest in the electric generation plant, which is used to provide electricity to MGE's customers.

MGE Construct is responsible for the construction of the facility. During the three and six months ended June 30, 2005, MGE Construct received service fees of $0.6 million and $1.3 million (pretax), respectively, from the State in relation to its role as EPC contractor for WCCF. The total fee of $5.0 million was recognized as services were rendered and was collected over a 22-month period. As of June 30, 2005, MGE Construct has recognized the entire $5.0 million service fee.

The total cost to construct WCCF is estimated to be $183.4 million, of which $104.7 million is MGE Power West Campus' estimated portion. As of June 30, 2005, MGE Power West Campus had incurred $102.4 million (excluding capitalized interest) of costs on the project, which is reflected in Property, Plant, and Equipment on MGE Energy and MGE's condensed consolidated balance sheets. Of this amount, $6.0 million has not yet been paid. MGE Power West Campus estimates an additional $2.3 million in capital expenditures for this project. These amounts have not yet been incurred or included in MGE Energy's or MGE's Property, Plant, and Equipment balance.

MGE Energy, MGE Power West Campus, and MGE Construct have contractually assumed certain risks related to the construction of WCCF. In the EPC Agreement, MGE Power West Campus is responsible for cost overruns and MGE Construct is responsible for the construction process of the entire facility, including paying liquidated damages relating to failure to achieve specified completion date guarantees and/or acceptance test capacity guarantees. In the second quarter, MGE Construct achieved mechanical completion prior to the guaranteed completion date for the electric, steam and chilled water portion of the facility. Also, the acceptance test guarantee was met for the electric portion of the facility. No liquidated damages were required to be paid for the completed guarantees on the electric portion of the asset. MGE Energy is the guarantor of MGE Construct's obligations under the EPC Agreement.

b. Lease Accounting.

MGE leases the assets owned by MGE Power West Campus and is responsible for operating the entire facility. On April 26, 2005, the facility lease between MGE and MGE Power West Campus commenced. The financial terms of the facility lease include a capital structure of 53% equity and 47% long-term debt, return on equity of 12.1%, and a lease term of 30 years. At the end of the lease term in 2035, MGE may, at its option, renew the facility lease for an additional term, purchase the generating facility at fair market value or allow the lease contract to end. In accordance with the provisions of SFAS No. 13, Accounting for Leases, MGE, as the lessee, accounts for the aforementioned lease arrangement as a capital lease and MGE Power West Campus, as the lessor, accounts for the lease as a direct financing leasing arrangement. Upon consolidation, certain accounts associated with the leasing transaction are eliminated.

On January 1, 2005, MGE began recovering in electric rates the costs associated with the lease payment for the West Campus Cogeneration plant. Recovery of these amounts was deferred until the lease term commenced. The deferred collections will be recognized into earnings ratably during 2005. At June 30, 2005, $2.5 million related to these collections was reflected as regulatory liabilities on MGE and MGE Energy's condensed consolidated balance sheets. As of June 30, 2005, MGE had recognized $0.8 million in revenues.

MGE received approval from the PSCW to collect approximately $12.1 million in carrying costs incurred by MGE Power West campus during construction of the facility. MGE is collecting these costs in rates over a period of 10 years. Of these costs, $4.1 million relates to the capitalized interest and the debt portion of the facility. These costs are recognized over the period in which the facility is being depreciated (40 years). The remaining amount of $8.0 million represents the equity portion and is recognized over the ten-year period for recovery in rates. As of June 30, 2005, $0.2 million had been recognized as revenue. These amounts are included in other nonregulated revenues on MGE Energy's and MGE's condensed consolidated statement of income. The difference between MGE's amortization of the costs for rate-making purposes over the ten-year recovery period and the recognition to revenue for the debt portion over 40 years is recorded as a liability on the condensed consolidated balance sheets.

11. ATC - MGE Energy and MGE.

As of June 30, 2005, MGE holds a 5% interest in ATC and accounts for the investment under the equity method of accounting due to its involvement with and ability to influence management activities. MGE has a seat on the board of directors and owns 20% of the voting stock of ATC Management, Inc., which manages and operates ATC. MGE records as equity in earnings of the investee its share of ATC's earnings as well as the amortization of the SFAS No. 109 regulatory liability and deferred investment tax credits related to the transmission assets transferred to ATC. For the three and six months ended June 30, 2005, MGE recorded equity earnings from its investment in ATC of $1.2 million and $2.3 million, respectively. MGE recorded transmission expense from ATC of $3.7 million and $7.5 million for the three and six months ended June 30, 2005, respectively.

On November 21, 2002, MGE and ATC entered into an interconnection agreement related to transmission system upgrades for WCCF. During the first quarter of 2005, MGE received its full payment from ATC for $13.0 million as reimbursement of its costs incurred to complete the upgrade.

In 2004, MGE made $3.5 million in additional capital contributions to ATC. No additional contributions have been made during the three or six months ended June 30, 2005. Dividend income received from ATC was $0.9 million and $1.7 million for the three and six months ended June 30, 2005, respectively.

12. Segment Information - MGE Energy and MGE.

MGE Energy operates in three business segments: electric utility operations conducted by MGE, gas utility operations conducted by MGE, and nonregulated energy operations. The electric utility business generates and distributes electricity and contracts for transmission service. The gas utility business purchases and distributes natural gas and contracts for the transportation of natural gas.

The nonregulated energy operations are conducted through subsidiaries of MGE Energy other than MGE. These subsidiaries have been formed to own and construct new electric generating capacity and have undertaken the construction of WCCF. The tables below show key information about all three segments, including the distribution of net assets, for the three and six months ended June 30, 2005 and 2004.

General corporate expenses include the cost of executive management, corporate accounting and finance, information technology, risk management, human resources and legal functions, and employee benefits that are allocated to electric and gas based on formulas prescribed by the PSCW. Identifiable assets are those used in MGE's operations in each segment. Assets not allocated consist primarily of cash and cash equivalents, restricted cash, investments, other receivables, and prepaid assets.

The following table shows segment information for MGE Energy's operations:

13. Commitments and Contingencies - MGE Energy and MGE.

a. Coal Contracts.

MGE has coal contracts related to the Blount plant. None of these contracts contain demand obligations. Fuel procurement for MGE's jointly owned Columbia plant is handled by Alliant, the operating company. If any minimum purchase obligations must be paid under these contracts, management believes such obligations would be considered costs of service and recoverable in rates.

b. Purchased Power Contracts.

MGE has several purchased power contracts to help meet future electric supply requirements. As of June 30, 2005, MGE's total commitments under its purchased power contracts for capacity are estimated to be $13.5 million in 2006, $10.5 million in 2007, $9.1 million in 2008 and 2009, and $9.2 million in 2010. Management expects to recover these costs in future customer rates.

MGE has negotiated firm transmission contracts related to the above purchased power contracts. As of June 30, 2005, MGE's total commitments for transmission are estimated to be $2.7 million in 2005 and $0.5 million in 2006. Management expects to recover these costs in future customer rates.

On November 18, 2004, a FERC order was issued which announced a new long-term transmission pricing structure as a result of the Midwest ISO and PJM markets. This order eliminates transmission charges on neighboring systems. Charges for network transmission services will be paid to ATC, the local transmission provider. This change will be effective on April 1, 2006.

On July 16, 2004, MGE signed a 20-year power purchase agreement for 40 MW of wind energy to be located near Waupun, Wisconsin. This agreement is not reflected in the purchased power commitment figures above as MGE is not currently able to estimate the related commitment as the site has not yet been constructed.

c. Natural Gas Supply, Transportation, and Storage Contracts.

MGE's natural gas supply, transportation and storage contracts require fixed monthly payments for firm supply, pipeline transportation, and storage capacity. The pricing components of the fixed monthly payments for the transportation and storage contracts are established by FERC but may be subject to change. As of June 30, 2005, these payments are estimated to be $14.6 million in 2006, $14.3 million in 2007, $14.1 million in 2008, $13.6 million in 2009, and $13.2 million in 2010. Management expects to recover these costs in future customer rates.

d. Environmental.

As a result of the Blount 69-kV transmission substation expansion, coal tar-contaminated soil and debris within the excavation zone has been removed and disposed of in accordance with a DNR approved "Removal Action Work Plan." MGE has paid $1.5 million in expenses to complete this cleanup and expects to recover cleanup costs in future gas rates. Carrying costs associated with the cleanup expenditures will not be recoverable. On June 23, 2005, the DNR issued a case closure letter related to the Blount 69 kV substation cleanup.

MGE is listed as a potentially responsible party for a site the EPA has placed on the national priorities Superfund list. The Lenz Oil site in Lemont, Illinois, was used for storing and processing waste oil for several years. This site requires clean up under the Comprehensive Environmental Response, Compensation and Liability Act. A group of companies, including MGE, is currently working on cleaning up the site. Management believes that its share of the final cleanup costs for the Lenz Oil site will not result in any materially adverse effects on MGE's operations, cash flows, or financial position. Insurance may cover a portion of the cleanup costs. Management believes that the cleanup costs not covered by insurance will be recovered in current and future rates. At June 30, 2005, a $0.1 million liability was accrued for this matter.

e. Chattel Paper Agreement and Other Guarantees - MGE and MGE Energy.

MGE makes available to qualifying customers a financing program for purchasing and installing energy-related equipment that will provide more efficient use of utility service at the customer's property. MGE is party to a chattel paper purchase agreement with a financial institution under which it can sell or finance an undivided interest, with recourse, in up to $10.0 million of the financing program receivables until August 31, 2005. At June 30, 2005, MGE had sold an outstanding $5.6 million interest in these receivables, which MGE accounted for as a sale under SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities - A Replacement of FASB Statement No. 125. MGE retains the servicing responsibility for these receivables.

MGE maintains responsibility for collecting and remitting loan payments from customers to the financial institution and does not retain any interest in the assets sold to the financial institution. As of June 30, 2005 and 2004, MGE has recorded a servicing asset of $0.2 million and $0.3 million, respectively. The loan assets are sold to the financial institution at cost, which approximates fair value in view of their market rates of interest. During the six months ended June 30, 2005 and 2004, MGE received approximately $0.1 million and $0.6 million, respectively, from the financial institution for the sale of loan assets. During those same periods, payments of $0.6 million and $1.3 million, respectively, were made by MGE to the financial institution.

MGE would be required to perform under its guarantee if a customer defaulted on its loan. The energy-related equipment installed at the customer sites is used to secure the customer loans. The length of the MGE guarantee to the financial institution varies from one to ten years depending on the term of the customer loan. Principal payments for the next five years on the loans are $0.8 million in 2006, $0.7 million in 2007, $0.9 million in 2008, $1.3 million in 2009, and $0.5 million in 2010.

MGE Energy has also guaranteed debt service payments on a development project. This guarantee begins in 2006.

f. WCCF Purchase Commitments - MGE Energy.

MGE and MGE Construct have entered into various contracts for the purchase of equipment and services related to the construction of WCCF. All contracts which were entered into by MGE have been assigned or are in the process of being assigned to MGE Construct. These contracts are summarized in the following table.

(In thousands)	Contract Total	Payments through June 30, 2005	Remaining Contract Amounts
Gas turbines	$ 30,296	$ 30,076	$ 220
Steam turbine	7,805	7,796	9
Heat-recovery steam generators	12,008	11,992	16
Chiller equipment	6,689	6,020	669
Prime contractors	53,432	50,971	2,461
Project management	8,846	8,846	-
Miscellaneous equipment	42,158	39,643	2,515
Total	$161,234	$155,344	$5,890*
* Amount represents remaining cash payments that are estimated per the terms of the contracts. Note that $4.0 million of this total amount has been incurred as of June 30, 2005. Consequently, this $4.0 million amount is accrued in the MGE and MGE Energy condensed consolidated balance sheets and reflected in the construction work in progress balance.

14. Regional Transmission Organizations.

On April 1, 2005, the MISO implemented its bid-based energy market. MISO is a FERC approved RTO that is required to provide real-time energy services and a market based mechanism for congestion management. MGE is a participant in this market. On April 1, 2005, MGE began offering substantially all of its generation on the MISO market and purchasing much of its load requirement from the MISO market in accordance with the MISO Tariff.

Additionally, on May 1, 2004, MGE became a member of PJM. PJM is a also an RTO. PJM is a neutral and independent party that coordinates and directs the operation of the region's transmission grid, administers a competitive wholesale electricity market, and plans regional transmission expansion improvements to maintain grid reliability and relieve congestion. MGE has three purchase power agreements, for a total of 115 MW, that are impacted by this market.

For transactions on the MISO and PJM market in which MGE buys and sells power within the same period to meet electric energy delivery requirements, these transactions are reported on the condensed consolidated income statement on a net basis. This treatment resulted in a $30.6 million and $31.6 million reduction to sales for resale and purchased power expense for the three and six months ended June 30, 2005, respectively.

15. Risk Management Activities.

As part of our regular operations, MGE enters into contracts including options, swaps, futures, forwards, and other contractual commitments to manage its exposure to interest rates, commodity prices, and gas margin. MGE evaluates its derivative contracts in accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended and interpreted. SFAS No. 133 requires MGE Energy and MGE to recognize all derivatives in the consolidated balance sheets at fair value, with changes in the fair value of derivative instruments to be recorded in current earnings or deferred in accumulated other comprehensive income (loss), depending on whether a derivative is designated as, and is effective as, a hedge and depending on the type of hedge transaction.

If the derivative qualifies for regulatory deferral subject to the provisions of SFAS No. 71, Accounting for the Effects of Certain Types of Regulation, the derivatives are marked to fair value pursuant to SFAS No. 133 and are offset with a corresponding regulatory asset or liability.

As a result of the firm transmission agreements that MGE holds on transmission paths in the MISO and PJM markets, MGE has been awarded FTRs. An FTR is a financial instrument that entitles the holder to a stream of revenues or charges based on the differences in hourly day ahead energy prices between two points on the transmission grid. FTRs are used by MGE to hedge the risk of increased congestion charges.

Due to the nature of these instruments, they qualify for regulatory deferral. As such, changes in the fair value of these instruments are recorded as regulatory assets or liabilities. At June 30, 2005, MGE had recorded a $0.1 million regulatory liability related to the FTRs held for the MISO and PJM markets.

MGE also utilizes future and basis swaps. These contracts stabilize the net position or price differential for gas injected into storage. These contracts also qualify for regulatory deferral. At June 30, 2005, MGE had recorded a $0.1 million regulatory liability related to these instruments.

16. Subsequent Events - MGE Energy and MGE.

a. Notice to Proceed.

On July 15, 2005, MGE Power Elm Road, LLC, received a notice to proceed from We Energies in conjunction with the Power the Future Generation Plan. MGE Power Elm Road, LLC, has 80 days from the receipt of the Notice to exercise its option to acquire an ownership interest in the proposed ERGS coal plants and has 40 days from that date to close the acquisition.

b. Rate Case.

On August 5, 2005, MGE filed additional information with the PSCW on its rate case application for 2006. MGE proposed an electric rate increase for ERGS carrying costs of $3.8 million (approximately 1.3%) for 2006 and $6.6 million (approximately 2.3%) for 2007, should it exercise its option to participate in ERGS. MGE also has requested to eliminate base rate case proceedings for 2007, but would propose to incorporate in the 2006 rate case an increase in 2007 electric rates to recover the 2007 ERGS carrying costs and an adjustment to reflect 2007 fuel rules costs.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.

General

MGE Energy is a holding company operating through subsidiaries in three business segments: electric utility operations, gas utility operations, and nonregulated energy operations. Our principal subsidiary is MGE, which conducts our electric utility and gas utility operations. MGE generates and distributes electricity to nearly 134,000 customers in Dane County, Wisconsin, including the city of Madison, and purchases and distributes natural gas to nearly 133,000 customers in the Wisconsin counties of Columbia, Crawford, Dane, Iowa, June au, Monroe, and Vernon. Other subsidiaries, which constitute our nonregulated energy operations, have been formed to own and construct new electric generating capacity.

We became the holding company for MGE on August 12, 2002, when MGE shareholders exchanged their shares of MGE common stock for shares of our common stock. The share exchange had no accounting effect on MGE's recorded assets, liabilities, revenues, or expenses.

MGE's electric and gas utility operations represent a substantial part of our assets, liabilities, revenues, and expenses. Our nonregulated operations relate principally to the construction and leasing of the cogeneration plant on the UW campus. The WCCF facility began producing electricity on April 26, 2005. The nonregulated operations relating to this cogeneration plant are included in MGE's consolidated financial statements as a result of FIN 46R (see Footnotes 2 and 9 of the Notes to the condensed consolidated financial statements for further information).

Executive Summary - MGE Energy and MGE

In the second quarter of 2005, our utility operations experienced an increase in electric retail sales of 6.3% and a 3.7% increase in retail gas deliveries as compared to the second quarter of 2004. Electric revenues increased $12.2 million for the three months ended June 30, 2005, as compared to the same period in 2004, due to warmer temperatures and the increase in rates effective in January 2005. Gas revenues increased $2.8 million due to higher costs of gas, slightly offset by a decrease in transportation volumes. Purchased power costs increased $6.0 million due to a planned and forced major outage at the Columbia plant and higher per-unit costs. Operations and maintenance expenses increased $1.9 million primarily due to higher maintenance expenses at the Columbia plant in conjunction with the aforementioned planned outage and higher transmission and production costs.

We anticipate relying on short- and long-term borrowings to support the remaining construction and capital expenditures for the cogeneration facility.

Our primary focus today and for the foreseeable future is our core utility customers at MGE. MGE continues to face the challenge of providing its customers with reliable power at competitive prices. MGE plans to meet this challenge by building more efficient generation projects and continuing its efforts to control operational costs. We believe it is critical to maintain a strong credit standing and financial strength in MGE as well as the parent company in order to accomplish these goals.

Rates. On December 21, 2004, the PSCW authorized MGE to increase 2005 electric revenues to cover rising fuel costs, commercial operation of WCCF, and increased transmission expenses. The PSCW also authorized increases in MGE's electric rates effective January 14, 2004, to cover rising fuel costs for electric generation and increased system demands.

During the six months ended June 30, 2004, a fuel credit in the amount of $3.2 million was refunded to customers. $2.8 million of the liability for this fuel credit was accrued during 2003 and $0.4 million was accrued in January 2004 as a decrease to other electric revenues.

Volume. During the three and six months ended June 30, 2005, there was a 6.3% and 2.8% increase, respectively, in total retail sales volumes. These increases are mainly due to warmer temperatures. Namely, cooling degree days for the three months ended June 30, 2005, were 248 compared to normal cooling days of 175.

Other Revenues. Other electric revenues for the three and six months ended June 30, 2005, decreased $0.4 million and $5.7 million, respectively, compared to the same period in the prior year. During the first and second quarters, MGE began recovering in electric rates the costs associated with the lease payments for the West Campus Cogeneration plant. These amounts were deferred on MGE's balance sheet and are now being recognized ratably over the lease term. For the six months ended June 30, 2005, a total reduction of $2.5 million was recorded to other revenues to defer these revenues. This amount is reflected as a regulatory liability on the condensed consolidated balance sheet.

The remaining decrease is attributable to the reversal of the 2003 fuel credit liability, which was refunded to customers in the first quarter of 2004. The actual fuel refund decreased retail revenues and is offset by an increase in other electric revenues. The fuel credit liability was previously recorded from August 2003 to January 2004 as a reduction in other electric revenues. These decreases are slightly offset by the recognition of deferred revenues due to the commencement of the WCCF lease term. On April 26, 2005, when the lease term commenced, MGE began recognizing into revenue amounts collected from the ratepayers for this leasing arrangement.

Sales for resale. For the three and six months ended June 30, 2005, sales for resale increased by $2.4 million and $2.5 million, respectively, when compared to the same periods in the prior year. Sales for resale include transactions conducted on the PJM and MISO markets since the establishment and our involvement in the PJM and MISO markets on May 1, 2004, and April 1, 2005, respectively. The increase in the sales for resale balance is a result of MGE's integration into the MISO market.

MGE has recorded transactions on the PJM and MISO markets in which we are buying and selling power within the same period to meet our electric energy delivery requirements on a net basis, resulting in a $30.6 million and $31.6 million reduction to sales for resale and purchased power expense for the three and six months ended June 30, 2005, respectively.

Electric fuel and purchased power

Fuel used for electric generation increased $2.8 and $1.7 million, or 23.4% and 7.2%, during the three and six months ended June 30, 2005, respectively, compared to the same periods in the prior year. These increases are due to an increase in the costs of internal generation, slightly offset by the outage at the Columbia plant. Due to this outage, MGE was required to rely more heavily on purchased power than on internal generation. The volume of internal generation decreased 12.4% during the six months ended June 30, 2005, as compared to the same period in the prior year.

Purchased power expense increased $6.0 million and $15.0 million during the three and six months ended June 30, 2005, respectively. These increased expenses reflect a 21.2% and 32.2% increase in purchased energy due to the aforementioned Columbia outage and a 23.9% and 22.9% increase in the per-unit cost of purchased power, respectively.

For the three and six months ended June 30, 2005, there were $30.6 million and $31.6 million reductions to purchased power expense, which resulted from the netting of transactions in the PJM and MISO markets in which we were buying and selling power within the same period to meet our electric energy delivery requirements.

Electric operating expenses

Electric operating expenses increased $1.6 million and $2.8 million during the three and six months ended June 30, 2005, respectively, compared to the same periods in 2004. These changes were the result of increases in production expenses, transmission expenses, and customer accounts, offset by decreases in administrative and general expenses.

Electric maintenance expense

For the three and six months ended June 30, 2005, electric maintenance expense increased $0.5 million and $0.8 million compared to the same periods in the prior year. These increases were due to increased maintenance expenses at the Columbia plant.

Gas Utility Operations

Gas deliveries and revenues

The following table compares MGE's gas retail revenues and gas delivered by customer class during each of the periods indicated:

Heating degree days (normal 4,349)				4,119	4,412	(6.6)

Gas revenues increased $2.8 million and $2.5 million for the three and six months ended June 30, 2005. These changes are related to the following factors:

(In millions)	Three Months Ended June 30, 2005	Six Months Ended June 30, 2005
Gas costs/rates	$2.1	3.7
Gas deliveries	0.8	(1.1)
Transportation and other effects	(0.1)	(0.1)
Total	$2.8	$2.5
Average rate per therm of residential customers

Gas costs/rates. The average rate per therm for the three and six months ended June 30, 2005, increased 7.5% and 3.9%, respectively, compared to the same periods in 2004. These increases are primarily a result of rising gas costs.

Retail gas deliveries. For the three months ended June 30, 2005, retail gas deliveries increased 3.7%. This increase is attributable to increased commercial and industrial use.

For the six months ended June 30, 2005, retail gas deliveries decreased 1.1%. This decrease was mainly a result of warmer temperatures reflected by a 6.6% decrease in the number of heating degree days during the period compared to the same period in the prior year. This decrease was slightly offset by an increase in volumes used by commercial and industrial customers.

Transportation and other revenues. Other revenues decreased a total of $0.1 million for the three and six months ended June 30, 2005, due to decreased income from the GCIM, offset by an increase in other revenues.

Natural gas purchased

For the three and six months ended June 30, 2005, natural gas purchased increased by $3.0 million and $5.1 million, respectively. The increases in the natural gas purchased were the result of a 17.9% and 9.0% increase in the market price of natural gas, which resulted in an increase of $2.5 million and $5.9 million. The increase for the three-month period ended June 30, 2005, was supplemented by an increase in the volume of gas purchased ($0.5 million). For the six months ended June 30, 2005, the increase was slightly offset by a decrease in the volume of gas purchased ($0.7 million).

Gas operating and maintenance expenses

Gas operating expenses decreased $0.2 million and $0.3 million, respectively, for the three and six months ended June 30, 2005, compared to the same periods a year ago. These decreases are attributable to decreases in gas distribution and customer service-related expenses.

Gas maintenance expenses increased $0.1 million and $0.4 million between the same periods. These increases are due to increased transmission related maintenance and increased general and administrative costs.

Other Nonregulated Operating Income - MGE Energy and MGE

For the three and six months ended June 30, 2005, MGE Construct received $0.6 million and $1.3 million from the State for services rendered in relation to its role as EPC contractor for the WCCF. For the three and six months ended June 30, 2004, MGE Construct received $0.7 million and $1.4 million, respectively, for these services. During the six months ended June 30, 2005, MGE Power West Campus recognized $0.2 million in nonregulated revenues for the recognition of a pro-ratable share of the carrying costs related to the facility. See Footnote 10 of the Notes to the condensed consolidated financial statements for further discussion.

Other operations and maintenance expense decreased $0.1 million for the three months ended June 30, 2005, compared to same period in the prior year. This decrease is primarily related to lower administrative and general expenses. Other operations and maintenance expense remained consistent for the six months ended June 30, 2005, compared to the same period in the prior year.

Depreciation expense

Depreciation expense increased $1.3 million and $1.8 million for the three and six months ended June 30, 2005, compared to the same periods in the prior year. These increases are due to an increase in electric and gas plant assets. For instance, during the second quarter of 2005, WCCF was put into service and MGE began depreciating the asset. For the six months ended June 30, 2005, electric depreciation expense was $10.1 million and gas depreciation expense was $3.9 million. This represents a $1.5 million and $0.3 million increase, respectively, in electric and gas depreciation expense from the same period in the prior year.

Other General Taxes - MGE Energy and MGE

The 5.6% increase in other general taxes for MGE Energy for the three and six months ended June 30, 2005, compared to the same periods in the prior year, is due to an increase in MGE's license fee tax. The annual license fee tax expense is based on adjusted operating revenues of the prior year. Tax rates have not increased.

Income Taxes - MGE Energy and MGE

MGE Energy's effective income tax rate of 38.4% for the six months ended June 30, 2005, is comparable to the effective income tax rate for the six months ended June 30, 2004 (38.7%).

Refer to Footnote 9 of the Notes to the condensed consolidated financial statements for discussion of the accounting for the tax deduction for qualified production activities provided by the American Jobs Creation Act of 2004.

Other Nonoperating Income - MGE Energy

Other nonoperating income for the three and six months ended June 30, 2005, decreased $0.1 million and $0.5 million when compared to the same periods in the prior year, respectively. For the three and six months ended June 30, 2005, this is comprised of equity earnings from ATC and other investments, and AFUDC-equity funds.

For the six months ended June 30, 2004, this balance includes $2.0 million in equity earnings from ATC, $0.3 million in AFUDC-equity funds, and $0.6 million from the gain on the sale of assets, offset by $0.2 million in other expenses.

Interest Expense - MGE Energy and MGE

For the three and six months ended June 30, 2005, interest expense decreased $0.5 million and $0.4 million, respectively, when compared to the same periods in the prior year. These decreases are a result of lower levels of short-term debt for much of the period, offset by a higher average interest rate on variable rate debt.

Minority Interest, Net of Tax

For the three and six months ended June 30, 2005, MGE Energy (through its wholly owned subsidiary MGE Power) had earned $1.4 million, net of tax, for its interest in MGE Power West Campus. This amount is recorded as minority interest expense, net of tax, on MGE's consolidated statement of income.

Contractual Obligations and Commercial Commitments - MGE Energy and MGE

As a result of a FERC order, there will be a change, effective April 1, 2006, to the Company's contractual obligations under the outstanding transmission contracts. See "Purchased Power Contracts" under Footnote 13 of the Notes to the condensed consolidated financial statements for further discussion.

There were no other material changes, other than from the normal course of business, to MGE Energy's and MGE's contractual obligations (representing cash obligations that are considered to be firm commitments) and commercial commitments (representing commitments triggered by future events) during the six months ended June 30, 2005. Further discussion of the contractual obligations and commercial commitments is included in MGE Energy's and MGE's annual reports on Form 10-K for the year ended December 31, 2004.

Liquidity and Capital Resources

Cash Flows

The following summarizes cash flows during the six months ended June 30, 2005 and 2004, respectively:

	MGE Energy		MGE
(In thousands)	2005	2004	2005	2004
Cash provided by/(used for):
Operating activities	$ 46,747	$ 54,932	$ 40,548	$ 48,578
Investing activities	(20,088)	(52,267)	(19,900)	(52,879)
Financing activities	(26,262)	(1,795)	(20,017)	4,693

Cash Provided by Operating Activities

Cash provided by MGE Energy's operating activities decreased $8.2 million, or 14.9%, for the first six months of 2005, compared to the same period last year. Current assets decreased $17.5 million during the six months ended June 30, 2005, primarily due to decreases in prepayments of $4.7 million, receivables of $4.0 million, and unbilled revenues of $9.0 million. Offsetting these decreases were increases in materials and supplies and other receivables. For the six months ended June 30, 2005, current liabilities decreased $2.5 million primarily due to decreases in accounts payable and other current liabilities, offset by an increase in accrued taxes and interest.

During the six months ended June 30, 2005, MGE began recovering in electric rates the costs associated with the lease payment for the West Campus Cogeneration plant. These amounts were deferred on MGE's balance sheet. These amounts are being recognized on a pro-rata basis over the 2005 lease year. At June 30, 2005, $2.5 million was collected from ratepayers and included in operating activities.

Also included in the operating section of MGE's cash flow statement is $1.4 million in minority interest, net of tax. As of June 30, 2005, MGE Energy (through its wholly owned subsidiary MGE Power) had earned $1.4 million in net income from its interest in MGE Power West Campus.

Cash Used for Investing Activities

Cash used for MGE Energy's investing activities decreased $32.2 million, or 61.6%, for the six months ended June 30, 2005, compared to the same period in the prior year. In March 2005, MGE collected $13.0 million from ATC for funds previously advanced to ATC in conjunction with the WCCF project. During the six months ended June 30, 2004, MGE had advanced ATC $2.0 million in conjunction with the WCCF project. There was a $1.6 million decrease in the amount of capital contributions made for the six months ended June 30, 2005, when compared to the same period in the prior year. This represents a $1.8 million decrease in the capital contributions made to ATC, offset by a $0.2 million increase in the capital contributions made to other investments. Additionally, capital expenditures decreased $16.4 million between the aforementioned periods. These decreases were offset by a decrease in cash provided by the sale of property ($0.6 million) and a decrease in cash provided by other investing activities ($0.2 million).

Cash used for MGE's investing activities decreased $33.0 million, or 62.4%, for the six months ended June 30, 2005, compared to the same period in the prior year. As mentioned above, in March 2005, MGE collected $13.0 million in funds previously advanced to ATC in conjunction with WCCF. Capital contributions made to ATC also decreased by $1.8 million for the period ended June 30, 2005, when compared to the same period in the prior year. Capital expenditures for the six months ended June 30, 2005, decreased $16.4 million when compared to the same period in the prior year. These decreases were offset by a decrease in the cash provided by other investing activities.

Cash Provided by Financing and Capital Resources

Cash used for MGE Energy's financing activities increased $24.5 million for the six months ended June 30, 2005, compared to the same period in the prior year primarily due to the net repayment of $13.2 million of short-term debt. Cash received as a repayment of the ATC advance (discussed above) was used to repay some of the outstanding short-term debt obligations. Cash dividends increased $1.4 million as the number of shares outstanding increased and the quarterly dividend increased from $0.338 for the three months ended March 31 and June 30, 2004, to $0.342 for the three months ended March 31 and June 30, 2005, respectively. Proceeds from the issuance of common stock decreased $11.3 million during the first six months of 2005, when compared to the same period last year. During the six months ended June 30, 2005, no shares were issued under the BOCM Agreement. Additionally, as of March 2005, shares to satisfy the Stock Plan were purchased on the open market, rather than new shares being issued. The aforementioned change resulted in a $0.3 million balance for the purchase of treasury stock. Cash used for other financing activities was $1.1 million for the six months ended June 30, 2005.

Cash used for MGE's financing activities increased $24.7 million for the six months ended June 30, 2005, compared to the same period last year. This increase is primarily due to the net repayment of short-term debt of $10.4 million. Cash dividends to the parent increased $0.5 million. Cash dividends from MGE to MGE Energy for the six months ended June 30, 2005, were $12.9 million, an increase of $0.5 million as compared to the same period during 2004. No equity contributions from the parent were received by MGE for the six months ended June 30, 2005. However, $4.4 million in equity contributions were received by MGE Power West Campus, which amounts are reflected as minority interest on the MGE consolidated balance sheet. Affiliate financing of WCCF decreased $1.0 million. For the six months ended June 30, 2005, MGE Power West Campus had made $0.6 million in repayments of affiliate financing, net. Cash used for other financing activities increased $0.5 million.

On March 29, 2005, MGE's $10 million line of credit expired. Bank lines of credit available to MGE and MGE Energy as of June 30, 2005, were $45 million and $105 million, respectively.

Capitalization Ratios

MGE Energy's capitalization ratios as of June 30, 2005, and December 31, 2004 were as follows:

	MGE Energy
	June 30, 2005	Dec. 31, 2004
Common shareholders' equity	58.3%	56.9%
Long-term debt	34.8%	34.1%
Short-term debt	6.9%	9.0%

MGE Energy's and MGE's Capital Requirements

MGE Energy's and MGE's liquidity is primarily affected by their capital requirements. During the six months ended June 30, 2005, capital expenditures for MGE Energy and MGE totaled $33.5 million, which included $10.8 million of capital expenditures for WCCF and $22.7 million of capital expenditures for utility operations.

As of June 30, 2005, MGE Energy's and MGE's remaining capital commitments related to WCCF are estimated to be $5.9 million. Of that amount, $4.0 million has been incurred as of June 30, 2005, and has been accrued on MGE Energy and MGE's condensed consolidated balance sheets and reflected in the Property, Plant, and Equipment balance.

MGE Energy anticipates that total 2005 capital expenditures will be approximately $60.1 million. MGE uses its internally generated funds and short-term debt to satisfy a majority of its capital requirements. Internally generated funds exceeded the funds used for construction during this year's first quarter. For larger capital investments, MGE would expect to finance these with additional long-term debt and capital contributions from MGE Energy.

During 2005, ATC solicited its investors for a 2005 voluntary capital contribution. In response to this request, MGE intends to make an estimated $1.4 million voluntary capital contribution in the fourth quarter of 2005. ATC, at its discretion, may ask for additional voluntary contributions for 2006. These amounts are not known at this time.

The following table shows MGE's current credit ratings. MGE Energy is not yet rated because it has not issued any debt securities.

	Standard & Poor's	Moody's
First Mortgage Bonds Unsecured Medium Term Notes Commercial Paper	AA AA- A1+	Aa2 Aa3 P1

MGE's access to the capital markets, including the commercial paper market and its financing costs in those markets, is dependent on its securities' ratings. None of MGE's borrowings are subject to default or prepayment due to downgrading of securities' ratings, although MGE's future interest expense may be affected by a change in those ratings.

WCCF

The cost to construct WCCF was expected to be approximately $183.4 million in total, of which MGE Power West Campus' portion is approximately $104.7 million. MGE Construct billed the State monthly for its share of the cost of WCCF in accordance with the EPC Agreement. As of June 30, 2005, MGE Power West Campus incurred $102.4 million (excluding capitalized interest) of costs on the project, which is reflected in Property, Plant, and Equipment on MGE Energy's and MGE's consolidated balance sheets. During the six months ended June 30, 2005, MGE Construct received a service fee of $1.3 million (pretax) from the State in relation to its role as EPC contractor for WCCF. The total fee of $5.0 million was recognized as services were rendered and was collected over a 22-month period. As of June 30, 2005, MGE Construct had recognized the entire $5.0 million in accordance with the EPC Agreement.

MGE received approval from the PSCW to collect approximately $12.1 million in carrying costs incurred by MGE Power West campus during construction of the facility. MGE is collecting these costs in rates over a period of ten years. Of these costs, $4.1 million relate to the capitalized interest and the debt portion of the facility. These costs are recognized over the period in which the facility is being depreciated (40 years). The remaining amount of $8.0 million represents the equity portion and is recognized over the ten-year period for recovery in rates. As of June 30, 2005, $0.2 million had been recognized as revenue.

During the six months ended June 30, 2005, MGE began recovering in electric rates the costs associated with the lease payments for the West Campus Cogeneration plant. These amounts have been deferred on MGE and MGE Energy's consolidated balance sheets. At June 30, 2005, $2.5 million related to these collections were reflected as regulatory liabilities on MGE and MGE Energy's consolidated balance sheets. These amounts will be reflected as revenues ratably over the period from the date of commercial operation through December 31, 2005. As of June 30, 2005, $0.8 million of these fees have been recognized.

MGE Energy, MGE Power West Campus, and MGE Construct have contractually assumed certain risks related to the construction of WCCF. In the EPC Agreement, MGE Power West Campus is responsible for cost overruns and MGE Construct is responsible for the construction process of the entire facility, paying liquidated damages relating to failure to achieve specified completion data guarantees and/or acceptance test capacity guarantees. As of June 30, 2005, MGE Construct achieved mechanical completion prior to the guaranteed completion date for the electric, steam and chilled water portion of the facility. Also, the acceptance test guarantee was met for the electric portion of the facility. No liquidated damages were required to be paid for these completed guarantees. MGE Energy is the guarantor of MGE Construct's obligations under the EPC Agreement.

Power the Future Generation

On February 23, 2001, MGE secured an option to own a portion of the advance technology, coal-fired base-load generation facilities proposed in We Energies' Power the Future Plan. Pursuant to an amended agreement reached on January 31, 2003. MGE has the option to acquire an undivided 8.33% (16.66% under certain conditions) ownership interest in each of the proposed coal plants or up to approximately 50 MW per unit. If the options on Units 1 and 2 are exercised, MGE Energy's share of capital costs for an 8.33% ownership interest in both units would be approximately $190 million.

The PSCW issued an order in November, 2003, approving We Energies' request for a CPCN for the two units. On November 29, 2004, the Dane County Circuit Court ruled on several lawsuits which challenged the PSCW's order authorizing We Energies to build these facilities on the site of their existing Oak Creek Power Plant. The Dane County Circuit Court vacated the PSCW order and remanded the order back to the PSCW for additional proceedings.

On June 28, 2005, the Supreme Court of Wisconsin reversed the Dane County Circuit Court's decision and upheld the PSCW's order in all respects. The CPCN granted by the PSCW was reinstated and is in full force and effect.

We have been informed by We Energies that they have received all the permits necessary to commence construction of the new units. Certain of these permits, however, continue to be contested, but remain in effect unless and until overturned by a reviewing body. Construction on this facility has begun.

On July 15, 2005, MGE Power Elm Road, LLC, received a notice to proceed from We Energies in conjunction with the Power the Future Generation Plan. MGE Power Elm Road, LLC, has 80 days from the receipt of the Notice to exercise its option to acquire an ownership interest in the proposed coal plants and has 40 days from that date to close the acquisition.

New Accounting Principles

See Footnote 9 of the Notes to the condensed consolidated financial statements for a discussion of new accounting pronouncements.

Regulatory Issues - Transmission

On April 1, 2005, the Midwest ISO implemented its bid-based energy market. Midwest ISO, a FERC approved RTO, is required to provide real-time energy services and a market-based mechanism for congestion management. This market-based platform for valuing transmission congestion is premised upon the LMP system that has been implemented in other states.

MGE received FTRs through the Midwest ISO allocation process. The Midwest ISO has also made available additional FTRs through an auction-based system run by the Midwest ISO. See Footnote 15 of the Notes to the condensed consolidated financial statements for further discussion.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

MGE Energy, through MGE, and MGE are potentially exposed to market risks associated with interest rates, commodity prices, weather, regulatory recovery, and equity returns. Neither MGE Energy nor MGE has any current exposure to foreign currency risk. MGE manages some risk exposure through risk management policies and uses derivative instruments.

Weather Risk

MGE's sales forecasts, used to establish rates, are set by the PSCW based upon estimated temperatures, which approximate 20-year averages. MGE's electric revenues are sensitive to the summer cooling season and, to some extent, to the winter heating season. A significant portion of MGE's gas system demand is driven by heating. MGE's gas margin (revenues less gas purchased) are collected under a combination of fixed and volumetric rates set by the PSCW based on "normal weather." As a result of weather-sensitive demand and volumetric rates, a portion of MGE's gas margin is at risk for warmer-than-normal weather. MGE may use weather derivatives, pursuant to its risk management program, to reduce the impact of weather volatility on its gas margins.

Interest Rate Risk

MGE Energy and MGE manage interest rate risk by limiting their variable rate exposure and by continually monitoring the effects of market changes on interest rates. MGE is not exposed to changes in interest rates on a substantial portion of its long-term debt until that debt matures and is refinanced at market rates. Borrowing levels under commercial paper arrangements vary from period to period depending upon capital investments and other factors.

Equity Price Risks - Pension-Related Assets

MGE currently funds its liabilities related to employee benefits through contributions to, and investment earnings on, trust funds. Changes in the market value of the assets held in the employee benefits trust funds affect MGE's expense and annuity payments. MGE intends to seek to mitigate some of its risk in this matter through future rate actions by the PSCW.

Commodity Price Risk

MGE has commodity price risk exposure with respect to the price of natural gas, electricity, coal, and oil. MGE employs established policies and procedures to reduce the market risks associated with changing commodity prices including the use of commodity and financial instruments. MGE's commodity risks are somewhat mitigated by the current ratemaking process in place for recovering electric fuel, purchased energy, and the cost of natural gas purchased for resale. MGE's electric fuel costs are subject to fuel rules established by the PSCW, which further mitigate commodity risk. Under the fuel rules, if electric fuel costs fall outside a 3.0% bandwidth set by the PSCW, MGE can apply for a fuel surcharge or may be required to issue a fuel credit to its customers. Under the PGA clause authorized by the PSCW, MGE passes through to customers the cost of gas, subject to certain limited incentives.

Under the fuel rules, MGE may include the costs and benefits of fuel price risk management tools implemented under a risk management plan approved by the PSCW. In 2004, the PSCW extended its conditional approval of MGE's Electric Procurement Risk Management Program through December 31, 2005.

Regulatory Recovery Risk

MGE burns natural gas in several of its peak electric generation facilities as a supplemental fuel, and in many cases, the cost of purchased power is tied to the cost of natural gas. MGE bears regulatory risk for the recovery from customers of such fuel and purchased power costs when they are higher than the base rate established in its current rate structure.

Credit Risks - Counterparty

Credit risk is the loss that may result from counterparty nonperformance. MGE Energy, through MGE, is exposed to credit risk primarily through its merchant energy business. MGE uses credit policies to manage its credit risk, which include utilizing an established credit approval process, monitoring counterparty limits, employing credit mitigation measures such as collateral or prepayment arrangements, and using netting agreements.

Item 4. Controls and Procedures.

MGE Energy

During the second quarter of 2005, MGE Energy's management, including the principal executive officer and principal financial officer, evaluated its disclosure controls and procedures related to the recording, processing, summarization, and reporting of information in its periodic reports that it files with the SEC. These disclosure controls and procedures have been designed to ensure that material information relating to MGE Energy, including its subsidiaries, is accumulated and made known to MGE Energy's management, including these officers, by other employees of MGE Energy and its subsidiaries as appropriate to allow timely decisions regarding required disclosure, and that this information is recorded, processed, summarized, evaluated, and reported, as applicable, within the time periods specified in the SEC's rules and forms. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision making can be faulty and breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. Also, MGE Energy does not control or manage certain of its unconsolidated entities and thus, its access and ability to apply its procedures to those entities is more limited than is the case for its consolidated subsidiaries.

As of June 30, 2005, these officers concluded that MGE Energy's disclosure controls and procedures were effective to accomplish their objectives. MGE Energy intends to continually strive to improve its disclosure controls and procedures to enhance the quality of its financial reporting.

During the quarter ended June 30, 2005, internal controls over financial reporting were implemented or modified in conjunction with MGE's participation in the MISO Day 2 Market. These internal controls primarily relate to revenue and cost recognition associated with power sales and purchases.

On April 26, 2005, WCCF's electric facilities began generating electricity. Additionally, on April 26, 2005, the lease arrangement between MGE and MGE Power West Campus commenced. Internal controls over financial reporting were implemented or modified in conjunction with these events.
