Notes to Unaudited Condensed Financial Statements
~~September 30,~~March 31, 2011 and 2010 ~~and 2009~~

(A): General. The condensed financial statements included in this report have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, the information furnished in this report reflects all adjustments (which include only normal recurring adjustments) and estimates necessary to fairly state, in all material respects, the results for the ~~three- and nine-month~~three-month periods ended ~~September 30, 2010~~March 31, 2011 and ~~2009.~~2010. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make the information presented not misleading. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2009,~~2010, as filed with the SEC. The results of operations for the ~~three- and nine-month periods~~three-month period ended ~~September 30, 2010~~March 31, 2011 are not necessarily indicative of results to be expected for the full year. As noted in our ~~2009~~2010 Form 10-K, substantially all of our sales are to our 39 electric distribution cooperative members and, thus, the receivables on the accompanying balance sheets are principally from our members. (See "Notes to Financial Statements" in our ~~2009~~2010 Form 10-K.)
(B): Fair Value Measurements. Authoritative guidance regarding fair value measurements for financial and non-financial assets and liabilities defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements.

The guidance establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

•: Level 1. Quoted prices from active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Quoted prices in active markets provide the most reliable evidence of fair value and are used to measure fair value whenever available. Level 1 primarily consists of financial instruments that are exchange-traded.
•: Level 2. Pricing inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Level 2 primarily consists of financial instruments that are non-exchange-traded but have significant observable inputs.
•: Level 3. Pricing inputs that include significant inputs which are generally less observable from objective sources. These inputs may include internally developed methodologies that result in management's best estimate of fair value. Level 3 financial instruments are those whose fair value is based on significant unobservable inputs.

Table of Contents

As required by the guidance, assets and liabilities measured at fair value are based on one or more of the following three valuation techniques:

1. Market approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business) and deriving fair value based on these inputs.

2. Income approach. The income approach uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts.

3. Cost approach. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (often referred to as current replacement cost). This approach assumes that the fair value would not exceed what it would cost a market participant to acquire or construct a substitute asset or comparable utility, adjusted for obsolescence.

The tables below detail assets and liabilities measured at fair value on a recurring basis for the periods ended ~~September 30, 2010~~March 31, 2011 and December 31, ~~2009.~~2010.

The assets included in the "Long-term investments" column in each of the Level 3 tables above are auction rate securities. As a result of market conditions, including the failure of auctions for the auction rate securities in which we invested, the fair value of these auction rate securities was determined using an income approach based on a discounted cash flow model. The discounted cash flow model utilized projected cash flows at current rates, which was adjusted for illiquidity premiums based on discussions with market participants. At ~~September 30, 2010,~~March 31, 2011, we held auction rate securities with maturity dates ranging from ~~March 15, 2028~~November 1, 2044 to December 1, 2045.

At December 31, ~~2009,~~2010, we had a ~~total~~ temporary impairment ~~of $1,690,000~~ on our ~~investments in~~ auction rate ~~securities.~~securities of $1,029,000. Based on the fair value of ~~these~~the auction rate securities ~~as of September 30, 2010,~~held at March 31, 2011, we recorded a ~~reduction~~($37,000) incremental adjustment to the temporary ~~impairment of approximately $184,000.~~impairment. The temporary impairment is reflected in "Accumulated other comprehensive deficit" on the ~~condensed unaudited balance sheets.~~Condensed Balance Sheets. The various assumptions we ~~utilize~~utilized to determine the fair value of our auction rate securities investments will vary from period to period based on the prevailing economic conditions. If the market for our auction rate securities investments should deteriorate, we may need to increase the illiquidity premium used in preparing a discounted cash flow model for these securities. A 25 basis point increase in the illiquidity premium used to determine the fair value of these investments at ~~September 30, 2010,~~March 31, 2011, would have resulted in aan additional decrease in the fair value of our auction rate securities investments by approximately ~~$1,310,000.~~ $562,000.

These investments were rated ~~either~~ A3 ~~or Aaa~~ by Moody's Investors Service and AAA by ~~Standard and Poor's~~Fitch as of ~~September 30, 2010.~~March 31, 2011. Therefore, it is expected that the investments will not be settled at a price less than par value. Because we ~~have the ability and intent~~do not intend to ~~hold these investments until~~sell unless we can recover our ~~original investment value,~~cost basis in a relatively short period of time, and it is not more likely than not that we will be required to sell the securities, we considered the investments to be ~~only~~ temporarily impaired at ~~September 30, 2010.~~March 31, 2011.

(C): Disclosures about Derivative Instruments and Hedging Activities. Our ~~executive~~ risk management committee provides general oversight over all risk management activities, including but not limited to, commodity trading and investment portfolio management. We use commodity trading derivatives, which are designated as hedging instruments under authoritative guidance for Accounting for Derivatives and Hedging, ~~Activities,~~ to manage our exposure to fluctuations in the market price of natural gas. Consistent with our rate-making treatment for energy costs which are flowed-through to our members, unrealized gains or losses on the natural gas swaps are reflected as an unbilled receivable. Within our nuclear decommissioning trust fund, derivatives including options, swaps and credit default swaps which are non-speculative, are utilized to mitigate volatility associated with duration, default, yield curve and the interest rate risks of the portfolio. We do not hold or enter into derivative transactions for trading or speculative purposes. Consistent with our rate-making

Table of Contents

treatment, unrealized gains or losses from the decommissioning trust fund are recorded as an increase or decrease to the regulatory asset or liability.

Under the natural gas swap arrangements, we pay the counterparty a fixed price for specified natural gas quantities and receive a payment for such quantities based on a market price index. These payment obligations are netted, such that if the market price index is lower than the fixed price, we will make a net payment, and if the market price index is higher than the fixed price, we will receive a net payment.

At ~~September 30, 2010,~~March 31, 2011, the estimated fair value of our natural gas contracts was an unrealized loss of approximately ~~$4,724,000.~~$2,069,000. See Note B for further discussion on fair value measurements of financial instruments.

We are exposed to credit risk as a result of entering into these hedging arrangements. Credit risk is the potential loss resulting from a counterparty's nonperformance under an agreement. We manage credit risk with policies and procedures for, among other things, counterparty analysis, exposure measurement, and exposure monitoring and ~~mitigation.~~mitigation in our natural gas hedging portfolio.

It is possible that volatility in commodity prices could cause us to have credit risk exposures with one or more counterparties. If such counterparties fail to perform their obligations, we could suffer

~~Table of Contents~~

a financial loss. However, as of ~~September 30, 2010,~~March 31, 2011, all of the counterparties with transaction amounts outstanding in our hedging portfolio are rated above investment grade by the major rating agencies or have provided a guaranty from one of their affiliates that is rated above investment grade.

We have entered into International Swaps and Derivatives Association Agreements with our natural gas hedge counterparties that mitigate credit exposure by creating contractual rights relating to creditworthiness, collateral, termination and netting (which allows us to use the net value of affected transactions with the same counterparty in the event of default by the counterparty or early termination of the agreement).

Additionally, we have implemented procedures to monitor the creditworthiness of our counterparties and to evaluate nonperformance in valuing counterparty positions. We have contracted with a third party to assist in monitoring counterparties' credit standing, including those experiencing financial problems, significant swings in credit default swap rates, credit rating changes by external rating agencies, or changes in ownership. Net liability positions are generally not adjusted as we use derivative transactions as hedges and have the ability and intent to perform under each of our contracts. In the instance of net asset positions, we consider general market conditions and the observable financial health and outlook of specific counterparties, forward looking data such as credit default swaps, when available, and historical default probabilities from credit rating agencies in evaluating the potential impact of nonperformance risk to derivative positions.

The contractual agreements contain provisions that could require us or the counterparty to post collateral or credit support. The amount of collateral or credit support that could be required is calculated as the difference between the aggregate fair value of the hedges and pre-established credit thresholds. The credit thresholds are contingent upon each party's credit standing and credit ratings from the major credit rating agencies. The collateral and credit support requirements vary by contract and by counterparty. We may only post credit support in the form of a letter of credit due to provisions within our Rural Utilities Service Loan Contract; however, we may receive collateral in the form of cash or credit support. As of ~~September 30, 2010,~~March 31, 2011, neither we nor any counterparties were required to post credit support or collateral under any of these agreements. If the credit-risk-related contingent features underlying these agreements were triggered on ~~September 30, 2010~~March 31, 2011 due to our credit rating being downgraded below investment grade, we could have been required to post letters of credit totaling up to ~~$4,724,000~~$2,069,000 with our counterparties.

(D): Investments in Debt and Equity ~~Securities:~~Securities. Under Accounting for Certain Investments in Debt and Equity Securities, investment securities we hold are classified as either available-for-sale or held-to-maturity. Available-for-sale securities are carried at market value with unrealized gains and losses, net of any tax effect, added to or deducted from patronage capital. Unrealized gains and losses from investment securities held in the decommissioning fund, which are also classified as available-for-sale, are directly added to or deducted from deferred asset retirement obligations costs. Held-to-maturity securities are carried at cost. There were no held-to-maturity securities as of ~~September 30, 2010~~March 31, 2011 and December 31, ~~2009.~~2010. All realized and unrealized gains and losses were determined using the specific identification method. Approximately ~~25%~~68% of these gross unrealized losses were in effect for less than one year. ~~The total gross unrealized~~These losses were primarily due to investments in fixed income securities held in the nuclear decommissioning trust fund. Consistent with our ratemaking, unrealized gains and losses from the decommissioning trust fund are recorded as an increase or decrease to the regulatory asset.

(E): Recently Issued or Adopted Accounting Pronouncements. In January 2010, the Financial Accounting Standards Board (FASB) issued Fair Value Measurements and Disclosures—Improving Disclosures about Fair Value Measurements. ~~The new guidance provides for improved disclosure requirements about fair value measurements and requires a reporting entity to disclose separately~~Effective March 31, 2011, the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. The guidance also clarifies that fair value measurement disclosures are required for each asset class. In the reconciliation for fair value measurements using significant unobservable inputs (Level 3), the standard ~~also~~ requires a reporting entity to present separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than as one number) in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). We adopted this new guidance beginning with the quarter ended March 31, 2010 except that the requirement to present Level 3 activity separately is not effective for us until the quarter ending March 31, 2011. TheOur adoption of the standard did not have a material effect on our disclosures.
(F): Accumulated Comprehensive Deficit. The table below provides detail of the beginning and ending balance for each classification of accumulated other comprehensive deficit along with the amount of any reclassification adjustments included in margin for each of the periods presented in the Condensed Statements of Patronage Capital and Membership Fees and Accumulated Other Comprehensive Deficit. There were no material changes in the nature, timing or amounts of expected (gain) loss reclassified to net margin from the amounts disclosed in our ~~2009~~2010 Form 10-K.

(G): Environmental Matters. There are a number of environmental matters that could have an effect on our financial condition or results of operations. At this time, the resolution of these matters is uncertain, and we have made no accruals for such contingencies and cannot reasonably estimate the possible loss or range of loss with respect to these matters.

As is typical for electric utilities, we are subject to various federal, state and local air and water quality requirements which, among other things, regulate emissions of pollutants, such as particulate matter, sulfur dioxide, nitrogen oxides and mercury into the air and discharges of other pollutants, including heat, into waters of the United States. Beginning in 2011, we have become subject to climate change regulations that impose restrictions on emissions of greenhouse gases (including carbon dioxide), through the Prevention of Significant Deterioration preconstruction permitting program. As a result, we will have to evaluate any major modifications that we plan to undertake at our plants to determine whether they will need to undergo new source review permitting for greenhouse gases, and, if they do, whether any control technology will need to be added. We are also subject to federal, state and local waste disposal requirements that regulate the manner of transportation, storage and disposal of various types of waste. ~~In the future, we may become subject to greenhouse gas emission restrictions as a result of regulation aimed at responding to climate change.~~

~~Table of Contents~~

In general, environmental requirements are becoming increasingly stringent. New requirements may substantially increase the cost of electric service by requiring changes in the design or operation of existing facilities or changes or delays in the location, design, construction or operation of new facilities. See ~~"BUSINESS—~~"Item 1—BUSINESS—ENVIRONMENTAL AND OTHER REGULATION" in our ~~2009~~2010 Form 10-K for a more detailed discussion of current and potential future ~~regulations.~~regulation. Failure to comply with these requirements could result in the imposition of civil and criminal penalties as well as the complete shutdown of individual generating units not in compliance. Certain of our debt instruments and credit agreements require us to comply in all material respects with laws, rules, regulations and orders imposed by applicable governmental authorities, which include current or future environmental laws and regulations. Should we fail to be in compliance with these requirements, it would constitute a default under such debt instruments. Although it is our intent to comply with applicable current and future regulations, we cannot provide assurance that we will always be in compliance with such requirements.

(H): Restricted cash. The restricted cash balance at ~~September 30, 2010~~March 31, 2011 consisted of ~~$6,299,000~~$168,700,000 of pollution control revenue bond proceeds utilized on April 1, 2011 for the refunding of certain pollution control revenue bonds and $6,301,000 of clean renewable energy bond proceeds on deposit with CoBank to fund a clean renewable energy project at the Rocky Mountain Pumped Storage Hydroelectric facility.
(I): Restricted short-term investments. At ~~September 30, 2010,~~March 31, 2011, we had ~~$80,771,000~~$15,125,000 on deposit with the Rural Utilities Service in the Cushion of Credit Account. The restricted funds will be utilized for future Rural Utilities Service/Federal Financing Bank debt service payments. The deposit earns interest at a Rural Utilities Service guaranteed rate of 5% per annum.
(J): Regulatory Assets and Liabilities. We apply the accounting guidance for Regulated Operations. Regulatory assets represent certain costs that are probable of recovery from our members in future revenues through rates under the wholesale power contracts with our members extending through December 31, 2050. Future revenues are expected to provide for recovery of previously incurred costs and are not calculated to provide for expected levels of similar future costs. Regulatory liabilities represent certain items of income that we are retaining and that will be applied in the future to reduce revenues required to be recovered from members.

The following regulatory assets and liabilities are reflected on the accompanying condensed balance sheets as of March 31, 2011 and December 31, 2010.

(K): Member Power Bill Prepayments. ~~In December 2008, we instituted~~We have a power bill prepayment program pursuant to which members can prepay their power bills from us at a discount based on our avoided cost of borrowing. The prepayments are credited against the participating members' power bills in the month(s) agreed upon in advance. The discounts are credited ~~each and every month~~ against the power bills and are recorded on our books as a reduction to member revenues. At ~~September 30, 2010,~~March 31, 2011, member power bill prepayments as reflected on the condensed balance sheets, including unpaid discounts, were ~~$84,683,000,~~$98,322,000, of which, ~~$64,963,000~~$55,822,000 is classified as current liabilities and ~~$19,720,000~~$42,500,000 as deferred credits and other liabilities.

Bond Issuance. In March ~~2010,~~2011, the Development Authority of Appling County (Georgia), the Development Authority of Burke County (Georgia) and the Development Authority of Monroe County (Georgia) issued, on our behalf, ~~$133,550,000~~$180,380,000 in aggregate principal amount of tax-exempt pollution control revenue bonds for the purpose of refunding certain pollution control revenue bonds previously issued by the development authorities on our behalf. WeThe Series 2011 bonds are term rate bonds with a 2.5% interest rate which is fixed through February 28, 2013. $168,700,000 in proceeds of the 2011 bonds were used to refund a like amount of Series 2007 and 2008 pollution control revenue bonds that were subject to remarketing and interest rate reset on April 1, 2011. In conjunction with this refunding, we provided notice of optional redemption of the prior bonds in March 2011 and redeemed the ~~prior~~ bonds on April 1, ~~2010.~~2011. The remaining proceeds of the 2011 bond issue were used to refund $11,680,000 of commercial paper that was used to refund a like amount of pollution control revenue bonds that matured on January 1, 2011.

Subsequent Events. WeOn April 8, 2011, we completed the previously announced acquisition of KGen Murray I and II LLC, a wholly owned subsidiary of KGen Power Corporation, which owned the Murray Energy Facility located near Dalton, Georgia. This facility consists of two natural gas-fired combined cycle units that have ~~evaluated subsequent events up until the time that our financial statements were issued.~~an aggregate summer planning reserve generation capacity of approximately 1,220 megawatts. The purchase price was $529,485,000, including working capital and other closing adjustments.

~~On November 9, 2010, we issued $450,000,000 of taxable first mortgage bonds primarily~~The acquisition also includes an existing power purchase and sale agreement with Georgia Power Company for the ~~purpose~~entire output of ~~funding~~Murray I through May 31, 2012. Initially, both units are planned to be operated independently of the other generating facilities we own and operate but will be integrated into our system as needed.

In connection with this acquisition, we closed a $260,000,000 three-year term loan with three banks to provide a portion of the ~~cost~~interim financing for this acquisition. We financed the remaining $269,485,000 through the issuance of ~~constructing Plant Vogtle Units No. 3~~commercial paper and ~~No. 4. A substantial portion~~draws under existing credit facilities. We have submitted a loan application to the Rural Utilities Service for long-term financing for this acquisition. For any amounts not funded through the Rural Utilities Service, we intend to issue taxable bonds.

With the completion of this acquisition, we have cancelled the development of the ~~proceeds were used~~previously announced 605 megawatt combined cycle plant and have withdrawn the corresponding loan application submitted to ~~repay outstanding short-term borrowings in connection with payments previously made for construction of this facility.

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

General

We are a Georgia electric membership corporation (an EMC) incorporated in 1974 and headquartered in metropolitan Atlanta. We are owned by our 39 retail electric distribution cooperative members. Our members are consumer-owned distribution cooperatives providing retail electric service in Georgia on a not-for-profit basis. Our principal business is providing wholesale electric power to our members through a combination of our generation assets and to, a lesser extent, power purchased from power marketers and other suppliers. As with cooperatives generally, we operate on a not-for-profit basis.

Forward-Looking Statements and Associated Risks

This Quarterly Report on Form 10-Q contains forward-looking statements, including statements regarding, among other items, (i) anticipated financing transactions by us, (ii) our future capital expenditure requirements and funding sources and (iii) achievement of a margins for interest ratio at the minimum requirement contained in our first mortgage indenture and, in the case that our board of directors approves a budget for a particular fiscal year that seeks to achieve a higher margins for interest ratio, such higher board-approved margins for interest ratio. These forward-looking statements are based largely on our current expectations and are subject to a number of risks and uncertainties, some of which are beyond our control. For a discussion of some factors that could cause actual results to differ materially from those anticipated by these forward-looking statements, see ~~"Item 1A—~~"Item1A—RISK FACTORS" ~~contained~~ in our ~~Annual Report on~~2010 Form ~~10-K for the fiscal year ended December 31, 2009.~~10-K. In light of these risks and uncertainties, there can be no assurance that events anticipated by the forward-looking statements contained in this Quarterly Report on Form 10-Q will in fact transpire.

Results of Operations

For the Three ~~and Nine~~ Months Ended ~~September 30,~~March 31, 2011 and 2010 ~~and 2009~~

Net Margin

Throughout the year, we monitor our operating results and, with board approval, make budget adjustments when and as necessary to ensure our targeted margins for interest ratio is achieved. Under the first mortgage indenture, we are required to establish and collect rates that are reasonably expected, together with our other revenues, to yield at least a 1.10 margins for interest ratio in each fiscal year. However, to enhance margin coverage during this period of generation ~~facility construction and acquisition,~~expansion, our board of directors approved budgets for 2010 and 2011 to achieve a 1.14 margins for interest ratio. As our ~~construction~~generation expansion program evolves, our board of directors will continue to evaluate the level of margin coverage and may choose to change the targeted margins for interest ratio in the future, although not below the 1.10 margins for interest ratio required under our first mortgage indenture.

Our net margin for the ~~three- and nine-month periods~~three-month period ended ~~September 30, 2010~~March 31, 2011 was ~~$13.8 million and $35.9~~$16.1 million compared to ~~$11.4 million and $39.8~~$14.6 million for the same ~~periods~~period of ~~2009. Through September 30, 2010, we have collected 106% of our targeted~~2010. We expect a net margin of ~~$33.8~~$38.3 million for the year ending December 31, ~~2010. This is typical as our management generally budgets conservatively and makes adjustments to the budget throughout the year so that net margins~~2011, which will achieve, but not exceed, the targeted margins for interest ratio of 1.14.

Operating Revenues

Our operating revenues fluctuate from period to period based on several factors, including weather and other seasonal factors, load requirements in our members' service territories, operating costs, availability of electric generation resources, our decisions of whether to dispatch our owned or

This increase in capacity revenues primarily resulted from higher budgeted fixed operations and maintenance expenses and depreciation expenses. Energy revenues were 39.7% and 23.0% higher for the three- and nine-month periods ended September 30, 2010 compared to the same periods of 2009.2010. Our average energy revenue per megawatt-hour from sales to members was ~~17.2% and 9.9% higher~~6.1% lower for the ~~three- and nine-month periods~~three-month period ended ~~September 30, 2010~~March 31, 2011 as compared to the same periods of ~~2009.~~2010. The ~~increase~~decrease in total energy revenues was primarily due to the pass-through to our members of ~~higher~~lower fuel costs (primarily due to ~~higher coal-fired generation)~~lower coal- and gas-fired generation due to outages at Plant Scherer and the Chattahoochee Energy Facility). For a discussion of fuel costs, see "—Operating Expenses" below.

Operating Expenses

Operating expenses for the ~~three- and nine-month~~three-month periods ended ~~September 30, 2010 increased 24.5% and 15.0%~~March 31, 2011 decreased 14.4% compared to the same ~~periods~~period of ~~2009.~~2010. This ~~increase~~decrease in operating expenses was primarily due to ~~higher~~lower fuel ~~costs, higher production expenses and higher depreciation expenses, offset somewhat by~~costs. In addition, a decrease in purchased power costs contributed to lower operating expenses.

~~Table of Contents~~

thus, the ~~increase~~decrease in coal- and gas-fired generation was the primary contributor to the ~~increase~~decrease in average fuel costs per megawatt-hour of generation.

Production expenses increased 19.6% and 17.6% for the three- and nine-month periods ended September 30, 2010 compared to the same periods of 2009. This increase is partly attributable to increased general operations and maintenance expenses at the jointly owned plants (Plants Hatch, Vogtle, Wansley and Scherer) during the three- and nine-month periods ended September 30, 2010 and partly due to operations and maintenance expenses for the Hawk Road and Hartwell Energy Facilities incurred in 2010. We acquired these facilities in May and October of 2009, respectively.

Total purchased power costs decreased ~~44.3% and 41.7%~~33.6% for the ~~three- and nine-month periods~~three-month period ended ~~September 30, 2010~~March 31, 2011 compared to the same ~~periods~~period of ~~2009.~~2010.

The average cost per kilowatt-hour of purchased power energy increased 115.7% and 50.0% for the three- and nine-month periods ended September 30, 2010 compared to the same periods of 2009.2010. The decrease in purchased power capacity costs is primarily attributable to the Hartwell acquisition. As part of the acquisition, we acquired an existing power purchase agreement we had in place with the former owners of Hartwell. The decrease in purchased power energy costs resulted from ~~(i)~~ a decrease in megawatt-hours acquired under our energy replacement program, which replaces power from our owned generation facilities with lower price spot market purchased power energy ~~(ii)~~and from lower realized losses incurred for natural gas financial contracts utilized for managing exposure to fluctuations in the market prices of natural ~~gas and (iii) no power purchases under the Hartwell power purchase agreement in 2010 as a result of our acquisition of Hartwell in October 2009.~~

Depreciation and amortization expense increased 3.3% and 11.2% in the three- and nine-month periods ended September 30, 2010 as compared to the same periods of 2009. The increase was primarily due to increased depreciation expense for Plants Scherer and Wansley related to capital expenditures for environmental compliance projects, and to a lesser extent, depreciation expense related to Hawk Road and Hartwell, which were acquired in May and October of 2009, respectively.gas.

Balance Sheet Analysis as of ~~September 30, 2010~~March 31, 2011

Assets

Cash used for property additions for the ~~nine-month~~three-month period ended ~~September 30, 2010~~March 31, 2011 totaled ~~$524.3~~$208.5 million. Of this amount, approximately ~~$308~~$96 million was associated with the construction expenditures for Plant Vogtle Units No. 3 and No. 4. The remaining expenditures were primarily for environmental control systems being installed at Plant Scherer, normal additions and replacements to existing generation facilities and purchases of nuclear fuel.

Cash and cash equivalents decreased by ~~$146.3~~$131.3 million in the ~~nine-month~~three-month period ended ~~September 30, 2010 and can be largely~~March 31, 2011. The decrease was primarily attributed to capital expenditures of ~~approximately $524.3~~$208.5 million for property additions, which were partially offset by $77 million in advances received from the Rural Utilities Service for environmental and ~~a net application~~general improvements.

Other significant uses of cash include principal and interest payments and payments to Georgia Power Company for operation and maintenance costs at our facilities co-owned with Georgia Power. Short-term borrowings and long-term debt proceeds of $297.4 million and $222.6 million, respectively, were significant sources of cash during the nine-month period ended September 30, 2010.Contents

The ~~$6.3 million~~ restricted cash balance at ~~September 30, 2010~~March 31, 2011 consisted of ~~the remaining~~$168.7 million of pollution control revenue bond proceeds obtained from ~~the issuance of clean renewable energy bonds in December 2009.~~a March 2011 bond refinancing.

The increase in receivables was largely due to these credits being utilized by the members during 2010. The receivable for amounts billed or billable to the members for their monthly power bills also increased by approximately $1.7 million in September 2010 compared to December 2009. Receivables from Smarr EMC for costs incurred for operation of its facilities also increased by $2.5 million. These increases were partially offset by a $7.8 million decrease in the receivable from the members associated with natural gas derivatives.

Capital—~~Table of Contents~~Liquidity

~~Prepayments and other current assets increased by $4.4 million in the nine-month period ended September 30, 2010 primarily as a result of an increase in prepaid insurance balances.~~

~~The $9.5 million decrease in deferred amortization of capital leases for the nine-month period ended September 30, 2010 was primarily due to regular monthly amortization.~~

The deferred tax asset represents an offset to the liability recorded for unrecognized tax benefits due to an uncertain tax position. We are carrying forward significant regular tax and alternative minimum tax net operating losses. As a result, any regular tax liability in open tax years related to an uncertain tax position would be offset by regular net operating losses. At December 31, 2009, we had recognized a $24.0 million liability for an uncertain tax position and consequently an offsetting $24.0 million deferred asset. The uncertain tax position relates to the 2006 tax year for which the U.S. federal statute of limitations expired during the third quarter of 2010. Accordingly, this liability and the related deferred tax asset were each reduced by $24.0 million during the third quarter of 2010 to zero.

The $3.5 million decrease in the deferred asset associated with retirement obligations in the nine-month period ended September 30, 2010 was primarily due to decommissioning fund earnings. The deferred asset increases or decreases to the extent of timing differences between recognized accretion expense associated with nuclear decommissioning and the amounts recovered through decommissioning fund earnings. Nuclear decommissioning accretion and related expenses of approximately $11.3 million and decommissioning fund net earnings of approximately $16.3 million resulted in the deferred charge decreasing by $5.0 million in the nine-month period ended September 30, 2010. Partially offsetting this decrease was a $2.0 million decrease in the unrealized gains associated with the nuclear decommissioning fund. Consistent with our ratemaking policy, unrealized gains or losses from the nuclear decommissioning fund are deducted from or added to the deferred asset associated with retirement obligations. The decrease in the nuclear decommissioning fund unrealized gains therefore increased the deferred asset by $2.0 million." herein.

Equity and Liabilities

Long-term debt and capital leases due within one year increased ~~$28.7~~$153.9 million primarily as a result of ~~scheduled debt maturities~~the $180.4 million refinancing transaction that occurred in March 2011. The principal payments for the refinanced pollution control revenue bonds were made April 1, 2011 and the ~~consequent reclassification~~balances were classified as current as of ~~certain long-term debt.~~

~~The $297.4 million increase in short-term borrowings was primarily~~March 31, 2011. For information regarding the March 2011 bond refinancing, see Note L of Notes to ~~fund construction~~Unaudited Condensed Financial Statements and "—Capital Requirements and Liquidity and Sources of ~~Plant Vogtle Units No. 3 and No. 4.~~Capital—Bond Financings" herein.

Accounts payable increased ~~$72.9~~$19.0 million in the ~~nine-month~~three-month period ended ~~September 30, 2010~~March 31, 2011 primarily due to a ~~$69.8~~$22.2 million increase in the payable to Georgia Power for operation, maintenance and capital costs, primarily associated with construction costs for Plant Vogtle Units No. 3 and No. 4. In addition, there was a ~~$3.8~~$3.4 million ~~increase~~decrease in the payable for natural gas, primarily due to ~~increased generation~~an unplanned outage at ~~the natural gas fired plants in September 2010 compared with December 2009.~~Chattahoochee.

The ~~$13.5~~$30.2 million decrease in accrued interest ~~during~~for the ~~nine-month~~three-month period ended ~~September 30, 2010~~March 31, 2011 was due to the normal timing differences between interest payments and interest expense accruals.

Accrued and withheld taxes decreased $16.8 million for the three-month period ended March 31, 2011 as a result of payments made (when due) for 2010 property taxes, which exceeded normal 2011 property tax accruals.

Member power bill prepayments represent funds received from the members for prepayment of their monthly power bills. At ~~September 30, 2010, $65.0~~March 31, 2011, $55.8 million of member power bill prepayments was classified as a current liability and ~~$19.7~~$42.5 million of member power bill prepayments was classified as a long-term ~~deferred~~ liability. During the ~~nine-month~~three-month period ended ~~September 30, 2010,~~March 31, 2011, approximately ~~$66.4~~$10.6 million of prepayments ~~was~~were received from the members and approximately ~~$182.2~~$24.8 million was applied to the members' monthly power bills. The application of member prepayments received in the prior year to the current year's power bills significantly reduced net cash provided by operations. For information regarding the power bill prepayment program, see Note JK of Notes to Unaudited Condensed Financial Statements and see ~~"Financial Condition—~~"—Capital Requirements and Liquidity and Sources of Capital—Liquidity" herein.

Other current liabilities increased by $5.5 million during the three-month period ended March 31, 2011 primarily due to $9.5 million accrued for major maintenance at the Hawk Road Energy Facility. Partially offsetting the increase was a $3.7 million decrease in accrued payroll as a result of the payout of 2010 performance pay.

Table of Contents

Other current liabilities decreased by $10.7 million during nine-month period ended September 30, 2010, primarily due to a $6.2 million decrease in accruals for other miscellaneous payables. This decrease was largely due to the payment and true-up of estimated operation and maintenance costs. The liability associated with natural gas derivatives also decreased by $7.8 million primarily due to the settlement of certain natural gas contracts. Partially offsetting these increases was a $3.6 million liability established as a result of the receipt of certain grant monies relating to energy efficiency programs.

Primarily as a result of incurring approximately $6.4 million of removal costs for the retirement of certain assets, accumulated retirement costs for other obligations decreased by $5.2 million during the nine-month period ended September 30, 2010.

The long-term contingent liability represents a liability recorded for unrecognized tax benefits. The $24 million decrease was the result of the expiration of the statute of limitations for the 2006 tax year. See the deferred tax asset discussion above for more information.

The $12.5 million decrease in the power sale agreement, which we assumed as part of the acquisition of Heard County Power L.L.C. in May 2009, in the nine-month period ended September 30, 2010 was due to regular monthly amortization.

Other deferred credits and liabilities increased $42.3 million in the nine-month period ended September 30, 2010 partially due to a $19.7 million liability established in 2010 for long-term contract retention payables associated with the Plant Vogtle Units No. 3 and No. 4 construction. The increase was also partially due to a $10.5 million increase in the regulatory liability established to defer the effects on net margin that result from Hawk Road Energy Facility operations. Also contributing to the increase was a $7.5 million increase in funding received from the members for future debt payments related to the Talbot and Chattahoochee Energy Facilities, as well as a $4.2 million increase in funding for the future overhaul of the combustion turbine plants.

Future Power Resources

To meet the energy needs of our members, we ~~have embarked on~~are in a period of generation ~~expansion program. On October 26, 2010, we entered into a non-binding term sheet with a third party to acquire natural gas-fired generation facilities.~~expansion. In addition to ~~significantly greater generation~~acquiring 2,020 megawatts of capacity through the purchase price for the facilities is expected to be less than the cost projected for us to construct a previously disclosed 605-megawatt combined cycle plant. The proposed acquisition remains subject to the completion of our due diligence and approval process, including subscription by our members and approval by our members and our Board of Directors, as well as negotiation of definitive agreements with the third party and, as a result, may not result in a completed transaction. If we complete this acquisition, we anticipate that it will close in early 2011.

If we acquire these facilities, we would revise our plans to construct future generation resources to reflect this additional generation capacity and our members' projected power supply needs. Completing this acquisition would affect two generation projects currently under development, a 605-megawatt combined cycle plant and the 100-megawatt Warren County biomass plant, which are projected to cost us approximately $750 million and $477 million, including allowance for funds used during construction, respectively. Upon closing, we would cancel the combined cycle plant and indefinitely defer the Warren County biomass plant while we continue to monitor regulatory and legislative uncertainties related to biomass electricity generation. These actions would reduce our previously disclosed projected capital expenditures by approximately $250 million through 2012 and by a total of approximately $1.2 billion through 2015, exclusive of expenditures at closing related to the purchase price of the ~~target facilities. To date, the expenditures on the combined cycle~~Hawk Road, Hartwell and ~~biomass plant~~Murray Energy Facilities, members have ~~not been material. This acquisition would have no effect on our participation~~subscribed to a 30% interest in ~~the construction of~~ Plant Vogtle Units No. 3

Recent Events in Japan. On March 11, 2011, a major earthquake and tsunami struck Japan and caused substantial damage to the nuclear generating units at the Fukushima Daiichi generating plant. According to published reports, the owner of these units is working to stabilize these units following a loss of operation of the cooling systems for the ~~quarterly period ended June 30, 2010.~~units, which led to the release of radiation. Both Georgia Power, on behalf of the co-owners, and we continue to monitor this situation as it develops.

In response to the events in Japan, the Nuclear Regulatory Commission has formed a task force to review operational and safety requirements for nuclear facilities in the U.S. which could potentially impact future operations and capital requirements. Additionally, the Nuclear Regulatory Commission has also received two petitions to suspend its decision-making processes related to both the AP1000 design certification and new nuclear construction generally in order to evaluate further any lessons learned from these events. The Nuclear Regulatory Commission has not acted on these petitions. To date, Georgia Power has not identified any immediate impacts to the licensing and construction of Vogtle Units No. 3 and No. 4 or the operation of our existing nuclear generating units.

The events in Japan have also created broader economic uncertainties that may affect the availability of equipment from Japanese manufacturers and future operating costs, including fuel, for our nuclear and other generating facilities. The ultimate outcome of these events on both our existing generation resources and the development of Vogtle Units No. 3 and No. 4 cannot be determined at this time. See "Item 1A—RISK FACTORS" in our 2010 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.

Environmental Regulations

~~Several environmental regulation-related developments have occurred since~~Since our ~~Quarterly Report on~~2010 Form ~~10-Q was filed for the second quarter of 2010~~10-K was filed with the ~~SEC. The~~SEC, the Environmental Protection Agency has published final maximum achievable control technology emission limits for industrial, commercial and institutional boilers. At the same time, EPA announced its intention to reconsider certain aspects of these standards, and is now in the process of developing a notice of reconsideration that will request additional comment on certain issues embedded in the rule. Thus, while the final rule ~~issued on June 22, 2010 revising~~is more favorable than the ~~sulfur dioxide standard~~proposed rule as it would apply to the boiler that was planned for the Warren County Biomass Project, there is still uncertainty as to whether there will be further changes in the rule that would apply to the emissions from that boiler. In addition, EPA has now ~~been challenged. After EPA's proposal of the Transport Rule on August 2, 2010, EPA issued a Notice of Data Availability on September 1, 2010, updating~~published proposed maximum achievable control technology emission limits for certain analyses used to derive the emissions limitations in the Transport Rule and issued a second Notice of Data Availability on October 27, 2010. Also, EPA received approval from the U.S. Court of Appeals for the D.C. Circuit to delay the finalization of the proposed national emission standards for hazardous air pollutants (including mercury) for ~~industrial boilers proposed on June 4, 2010 for one month until January 16, 2011. This rule~~coal and oil-fired electric generating units. EPA has stated its intention to finalize this proposal later in 2011, after it has considered and responded to comments that are now being prepared in response to the ~~proposed Transport Rule could undergo substantial revision prior to finalization, at which time they too might be challenged.~~proposal. We cannot predict at this time whether any of these developments will ultimately result in the further regulation of emissions from our existing or future power plants, or the effects of any such regulation, including any resulting capital requirements.

Due to the significant amount of expenditures we are incurring relating to environmental compliance projects and acquisition and construction ~~or acquisition~~ of new generation facilities, we are currently funding our capital requirements through a combination of funds generated from operations and short-term and long-term borrowings. In particular, we are using commercial paper, ~~and short-term~~revolving credit facilities and term loans to provide interim financing for the environmental compliance expenditures, for the acquisition of generation facilities and for new generation construction until permanent financing for these projects is put in place. In ~~November 2010~~late 2011 we ~~issued $450~~plan to issue approximately $400 million of long-term first mortgage bonds to fund a portion of the cost of constructing ~~Plant~~ Vogtle Units No. 3 and No. 4 and ~~used a substantial portion of~~will use the bond proceeds to repay short-term borrowings that ~~were~~are providing interim funding for this same purpose.

For a more detailed discussion of our plans regarding financing of these facilities, see "—Financing Activities."

In order to further enhance our liquidity position during the peak years of ~~new~~our generation ~~construction,~~expansion program, we are currently ~~anticipate a~~in the process of restructuring and ~~related~~ upsizing of certain of our short-term credit facilities, including the $475 million commercial paper backup line of credit, the $50 million CoBank line of credit and a $136 million letter of credit facility ~~sometime in 2011. The exact timing, size and term of the restructured~~currently providing credit ~~facilities will be influenced by many factors, including the ultimate size~~enhancement on certain of our ~~construction program, the timing~~variable rate pollution control bonds. We expect to replace these facilities with a new

four year revolving credit facility of up to $1.3 billion that can be used to support commercial paper issuance, to advance funds for working capital purposes and to issue letters of credit thereunder. Bank of America will continue to serve as administrative agent under this restructured facility. A closing on this new ~~generation facilities~~facility is expected by June 2011. We also plan to renew and ~~overall market conditions.~~upsize our $50 million National Rural Utilities Cooperative Finance Corporation (CFC) line of credit later this year.

Under the commercial paper program, ~~we are~~our board of directors has authorized us to issue commercial paper in amounts that do not exceed the amount of any committed backup lines of credit in place, thereby providing 100% dedicated backup support for any paper outstanding. We periodically assess our needs in order to determine the appropriate amount of commercial paper backup to ~~maintain and currently~~maintain. In connection with the increase in the size of our main revolving credit facility to approximately $1.3 billion, we will be upsizing the size of our commercial paper program accordingly. Once all the restructured credit facilities have closed, we expect to have in place credit facilities in the aggregate totaling approximately $1.9 billion. We believe this amount of liquidity will be more than sufficient to cover our interim funding needs through the period of generation expansion and to provide a ~~$475 million committed backup credit facility provided by eight participant banks, with Bank of America serving as administrative agent for this facility.~~reasonable cushion to operate our business.

Along with the lines of credit from CoBank, ~~the National Rural Utilities Cooperative Finance Corporation (CFC)~~CFC and JPMorgan Chase Bank, funds may also be advanced under the commercial paper backup line of credit ~~supporting commercial paper~~ for general working capital purposes. In addition, under certain of our committed credit facilities we have the ability to issue letters of credit totaling $450 million in the aggregate, of which approximately ~~$180~~$336 million remained available at ~~September 30, 2010.~~March 31, 2011. However, any amounts related to issued letters of credit will reduce the amount available to draw as working capital under those facilities. Also, due to the requirement to have 100% dedicated backup for any commercial paper outstanding, any amounts drawn under the commercial paper backup line for working capital or related to issued letters of credit will reduce the amount of commercial paper that we can issue.

Under the $250 million line of credit with CFC, we have the option of converting any amounts outstanding under the line of credit to a term loan with a maturity no later than December 31, 2043. Any amounts drawn under the $250 million CFC line of credit, as well as any amounts converted to a term loan, will be secured under our first mortgage indenture.

Several of our line of credit facilities contain a similar financial covenant that requires us to maintain minimum levels of patronage capital. At ~~September 30, 2010,~~March 31, 2011, the required minimum level was ~~$544.8~~$570 million and our actual patronage capital was ~~$598.1~~$612 million. An additional covenant contained in several of our credit facilities limits our secured indebtedness and our unsecured indebtedness, both as defined by these credit facilities, to $8.5 billion and $4.0 billion, respectively. At ~~September 30, 2010,~~March 31, 2011, we had approximately ~~$4.5~~$5.2 billion of secured indebtedness and ~~$666~~$392 million of unsecured indebtedness outstanding, which was well within the covenant thresholds.

We also have a power bill prepayment program that provides us with an additional source of liquidity. Under the program, members can prepay their power bills from us at a discount for an agreed upon number of months in advance, after which the prepayments are credited against the participating members' monthly power bills. The discount is comparable to our avoided cost of borrowing. As of ~~September 30, 2010,~~March 31, 2011, the balance of member prepayments received but not yet credited to their power bills was ~~$84.7 million, which represented prepayments from sixteen members participating in the program.~~$98 million. We began applying the prepayments against participating members' power bills in 2009 and will continue doing so through May 2015, with the majority of the remaining balance scheduled to be applied in ~~2011.~~2011 and 2012. For more information regarding the power bill prepayment program, see Note JK of Notes to Unaudited Condensed Financial Statements.

At ~~September 30, 2010,~~March 31, 2011, current assets included ~~$81~~$15 million of restricted short-term investments pursuant to deposits made to a Rural Utilities Service Cushion of Credit Account.

We intend to put in place by year-end 2010 an indenture for unsecured debt securities to provide an additional financing alternative, most notably in connection with interim financing related to generation facility acquisitions and new generation construction.

Bond Financings. InOn March ~~2010,~~31, 2011, the Development Authority of Appling County (Georgia), the Development Authority of Burke County (Georgia) and the Development Authority of Monroe County (Georgia) issued, on our behalf, ~~$133.6~~$180.4 million in aggregate principal amount of tax-exempt pollution control revenue bonds for the purpose of refunding certain pollution control revenue bonds previously issued by the development authorities on our behalf to finance or refinance the costs of our undivided interests in certain air or water pollution control and sewage or solid waste disposal facilities. The bonds were issued as ~~variable~~two-year term rate ~~demand~~ bonds ~~backed by an irrevocable direct-pay letter of credit for each series of bonds issued by Bank of America.~~with a 2.5% interest rate fixed through February 28, 2013. The bonds are secured under our first mortgage indenture.

~~On November 9, 2010,~~In late 2011, we ~~issued $450~~plan to issue approximately $400 million of taxable first mortgage bonds primarily for the purpose of funding a portion of the cost of constructing Plant Vogtle Units No. 3 and No. 4. ~~A substantial portion of the~~The proceeds ~~were~~will be used to repay outstanding short-term borrowings in connection with payments ~~previously made~~due during 2011 for construction of ~~this facility.~~these units. The first mortgage bonds ~~were secured under our first mortgage indenture.~~

We are evaluating the potential for an issuance of a modest amount of new tax-exempt debt in connection with costs related to pollution control equipment being installed at coal-fired Plant Scherer, but the timing and exact amount of this new debt, if any, is uncertain at this time. If issued, this tax-exempt debt will be secured under our first mortgage indenture.

~~Table~~Interim Financing for the Murray Acquisition. In early April 2011, we closed a $260 million three-year term loan to provide funds for a portion of ~~Contents~~the cost of acquiring the Murray Energy Facility. The balance of the acquisition cost was funded with commercial paper and drawings under our existing short-term credit facilities.

Rural Utilities Service-Guaranteed Loans. We currently have five approved Rural Utilities Service-guaranteed loans, being funded through the Federal Financing Bank, totaling $1.2 billion that are in the process of being drawn down, with ~~$940~~$830 million remaining to be advanced. Two of these loans were approved in the third quarter of 2010, including a loan relating to the acquisition of the Hawk Road Energy Facility ($203.1 million) and a loan relating to the acquisition of the Hartwell Energy Facility ($170 million).

We also have three Rural Utilities Service-guaranteed loan applications pending, totaling ~~approximately $1.3~~$1.1 billion, including a loan ~~application~~applications related to the Warren County biomass plant, athe Murray Energy Facility and to general improvements at existing generation facilities. Actions on the Murray and general improvements loans are anticipated in 2011. The previously submitted loan application related to the 605 MWmegawatt gas-fired combined cycle plant, ~~and a loan application related to general improvements at existing generation facilities (action on this general improvements loan is anticipated~~which was cancelled in ~~2011).~~ connection with the Murray acquisition, has been withdrawn.

The ~~President's~~Federal budget ~~proposal~~ for fiscal year 2011 (which began on October 1, 2010) ~~has not yet been~~was adopted ~~but if adopted would prohibit~~in April 2011. Rural Utilities Service funding for fiscal year 2011 remains unchanged from that in fiscal year 2010. Additionally, the previously proposed restrictions to eligibility for funding in fiscal year 2011 were not included. However, the President's proposed budget for fiscal year 2012 does include a modest reduction to the overall funding level as well as prohibitions against funding for (i) improvements to ~~existing~~ fossil-fueled generation ~~facilities~~ unless the improvements are related to carbon-capture projects, except up to $2 billion may be used for environmental improvements that would reduce emissions, and (ii) construction of new fossil-fueled generation facilities. Nonetheless we have submitted a loan application for Murray, and should members subscribe to any additional fossil-fueled facilities, ~~including the gas-fired facilities that we may acquire,~~ we anticipate filing loan applications for those facilities as well to the extent Rural Utilities Service ~~regulations~~lending

authority in place at that time allow us to do so. ~~As such, should we complete the acquisition of the natural gas-fired facilities discussed above under "~~~~Future Power Resources,~~" we intend to submit a loan application to the Rural Utilities Service for long-term financing of the acquired facility, and at the same time would withdraw our loan application previously submitted to the Rural Utilities Service for the 605 MW gas-fired combined cycle plant. For any amounts not funded through the Rural Utilities Service, we would most likely issue taxable bonds secured under our first mortgage indenture. We are considering a variety of alternatives available to us for interim financing in connection with the potential acquisition of the gas-fired facilities including, but not limited to, using cash on hand, drawing down on our existing credit facilities or new unsecured credit facilities and issuing unsecured notes in transactions registered or exempt under the Securities Act of 1933, as amended (see "~~Our Indenture~~~~").~~

For a more detailed discussion regarding the Rural Utilities Service's current position on funding of generation facilities and a general discussion of the federal programs administered by it, see "BUSINESS—OGLETHORPE POWER CORPORATION—Relationship with Rural Utilities Service" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.bonds.

All of the approved Rural Utilities Service loans are expected to be funded through the Federal Financing Bank and guaranteed by the Rural Utilities Service, and the debt will be secured under our first mortgage indenture.

Department of Energy-Guaranteed Loans. We have ~~signed~~ a conditional term sheet with the Department of Energy that sets forth the general terms of a loan and related loan guarantee that would fund approximately 70% of the estimated $4.2 billion cost to construct our 30% undivided share of Plant Vogtle Units No. 3 and No. 4, not to exceed $3.057 billion. The loan structure would entail a loan that is expected to be funded by the Federal Financing Bank carrying a federal loan guarantee provided by the Department of Energy, with the debt secured under our first mortgage indenture.

We are working with the Department of Energy to finalize the loan guarantee. However, final approval and issuance of a loan guarantee by the Department of Energy is subject to receipt of the combined construction permits and operating licenses for Plant Vogtle Units No. 3 and No. 4 from the Nuclear Regulatory Commission, negotiation of definitive agreements, completion of due diligence by the Department of Energy and satisfaction of other conditions. Therefore, there can be no assurance that the Department of Energy will ultimately issue the loan guarantee to us. We anticipate that any Plant Vogtle costs not funded under the Department of Energy loan guarantee program would be financed through the issuance of taxable bonds.

~~Table of Contents~~

Of the approximately $1.2 billion of currently estimated project costs not expected to be funded under the Department of Energy loan guarantee program, we have already financed $850 million through the issuance of first mortgage bonds. WeAs discussed above, we expect to issue another approximately $400 million of first mortgage bonds for this purpose ~~sometime~~ in late 2011.
