NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1 — Basis of Presentation

NRG Energy, Inc., or NRG or the Company, is an integrated wholesale power generation and retail electricity company that aspires to be a leader in the way the industry and consumers think about, use, produce and deliver energy and energy services in major competitive power markets in the United States. First, NRG is a wholesale power generator engaged in the ownership and operation of power generation facilities; the trading of energy, capacity and related products; and the transacting in and trading of fuel and transportation services. Second, NRG is a retail electricity company engaged in the supply of electricity, energy services, and cleaner energy products to retail electricity customers in deregulated markets through its Retail businesses, which include Reliant Energy, Green Mountain Energy and Energy Plus. Finally, NRG is focused on the deployment and commercialization of potential disruptive technologies, like electric vehicles, Distributed Solar and smart meter technology, which have the potential to change the nature of the power supply industry.

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with the Securities and Exchange Commission's, or SEC's, regulations for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the Company's financial statements in its Annual Report on Form 10-K for the year ended December 31, 2011, or 2011 Form 10-K. Interim results are not necessarily indicative of results for a full year.

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary to present fairly the Company's consolidated financial position as of June 30, 2012, and the results of operations, comprehensive income/(loss) and cash flows for the three and six months ended June 30, 2012, and 2011.

Use of Estimates

The preparation of consolidated financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during the reporting period. Actual results could be different from these estimates.

Note 2 — Summary of Significant Accounting Policies 

Other Cash Flow Information

NRG’s investing activities exclude capital expenditures of $844 million which were accrued and unpaid at June 30, 2012, primarily for solar projects under construction.

Noncontrolling Interests

The following table reflects the changes in NRG's noncontrolling interest balance:

 	(In millions)	
Balance as of December 31, 2011	$	183	
 	
Cash contributions	238	
 	
Comprehensive income attributable to noncontrolling interest	9	
 	
Balance as of June 30, 2012	$	430	

11

Tax Credits

NRG accounts for income taxes in accordance with Accounting Standards Codification, or ASC, 740, Income Taxes, or ASC 740, which requires that the Company use the asset and liability method of accounting for deferred income taxes and provide deferred income taxes for all significant temporary differences, as further described in Note 2,  Summary of Significant Accounting Policies , to the Company's 2011 Form 10-K. NRG reduces its current income tax expense in the consolidated statement of operations for any investment tax credits, or ITCs, that are not convertible into cash grants, as well as other tax credits, in the period the tax credit is generated. ITCs that are convertible into cash grants, as well as the deferred income tax benefit generated by the difference in the financial statement and tax bases of the related assets, are recorded as a reduction to the carrying value of the underlying property and subsequently amortized to earnings on a straight-line basis over the useful life of each underlying property.

Recent Accounting Developments

Effective January 1, 2012, the Company adopted the provisions of Accounting Standards Update, or ASU, No. 2011-05, Comprehensive Income (Topic 220) Presentation of Comprehensive Income , or ASU No. 2011-05, and began presenting the total of comprehensive income, the components of net income and the components of other comprehensive income in two separate but consecutive statements.  The provisions of ASU No. 2011-05 are required to be adopted retroactively.  As this guidance provides only presentation requirements, the adoption of this standard did not impact the Company's results of operations, cash flows or financial position.

Note 3 — Business Acquisitions and Dispositions 

2012 Dispositions

Agua Caliente
On January 18, 2012, the Company completed the sale of a 49% interest in NRG Solar AC Holdings LLC, the indirect owner of the Agua Caliente project, to MidAmerican Energy Holdings Company, or MidAmerican. A majority of the $122 million of cash consideration received at closing represented 49% of construction costs funded by NRG's equity contributions. The excess of the consideration over the carrying value of the divested interest was recorded to additional paid-in capital. MidAmerican will fund its proportionate share of future equity contributions and other credit support for the project. NRG continues to hold a majority interest in and consolidate the project.

Saale Energie GmbH
On July 17, 2012, the Company completed the sale of its 100% interest in Saale Energie GmbH, which holds a 41.9% interest in Kraftwerke Schkopau GbR and a 44.4% interest in Kraftwerke Schkopau Betriebsgesllschaft mbH, collectively, Schkopau.  Schkopau holds a fixed 400 MW participation in the 900 MW Schkopau Power Station located in Germany.  In connection with the sale of Schkopau, NRG entered into a foreign currency swap contract to hedge the impact of exchange rate fluctuations on the sale proceeds of €140 million. The Company received cash consideration, net of selling expenses, of $174 million, which included $4 million related to the settlement of the swap contract that was recorded as a gain within Other income, net in the third quarter.  The cash consideration approximated the book value of the net assets, including cash of $41 million, and liabilities, on the date of the sale.

Within the balance sheet as of June 30, 2012, the Company reclassified the Schkopau assets held for sale into Prepayments and other current assets and the liabilities held for sale into Accrued expenses and other current liabilities.

Pending Acquisition

On July 20, 2012, the Company entered into an agreement to acquire GenOn Energy, Inc., or GenOn. GenOn, a generator of wholesale electricity, has baseload, intermediate and peaking power generation facilities using coal, natural gas and oil, totaling approximately 22,700 MW. The Company will issue, as consideration for the acquisition, 0.1216 shares of NRG common stock for each outstanding share of GenOn, including restricted stock units outstanding, on the acquisition date, except for fractional shares which will be paid in cash. The acquisition is subject to customary conditions, including shareholder approval of the share issuance and regulatory approvals, and is expected to close by the first quarter of 2013.

12

2011 Acquisitions

The Company's acquisitions that are considered business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805,  Business Combinations , or ASC 805, with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair values on the acquisition date. The provisional amounts recognized are subject to revision until the evaluations are completed and to the extent that additional information is obtained about the facts and circumstances that existed as of the acquisition date, are required to be finalized within a measurement period not to exceed one year. The Company made several acquisitions in 2011, which were recorded as business combinations under ASC 805, for which the accounting was not finalized as of December 31, 2011. See Note 3,  Business Acquisitions and Dispositions  and Note 12,  Debt and Capital Leases , in the Company's 2011 Form 10-K, for additional information related to these acquisitions.

The accounting for the acquisitions of Energy Plus, California Valley Solar Ranch, or CVSR, Agua Caliente and Ivanpah were completed as of March 31, 2012, at which point the provisional fair values became final with no material changes.

Note 4 — Nuclear Innovation North America LLC, or NINA, Impairment Charge 

As discussed in detail in Note 4, Nuclear Innovation North America LLC Developments, including Impairment Charge, to the Company's 2011 Form 10-K, NRG deconsolidated NINA as of March 31, 2011, and recorded an impairment charge of $492 million for the six months ended June 30, 2011, including $481 million in the quarter ended March 31, 2011 for the full amount of its investment, and $11 million in the quarter ended June 30, 2011.

Note 5 — Fair Value of Financial Instruments 

This footnote should be read in conjunction with the complete description under Note 5, Fair Value of Financial Instruments , to the Company's 2011 Form 10-K.

For cash and cash equivalents, funds deposited by counterparties, restricted cash, cash collateral paid and received in support of energy risk management activities, and restricted cash supporting the funded letter of credit facility, the carrying amount approximates fair value because of the short-term maturity of those instruments. Debt securities, equity securities, trust fund investments, which are comprised of various U.S. debt and equity securities, and derivative assets and liabilities are carried at fair market value.
The estimated carrying values and fair values of NRG's recorded financial instruments not carried at fair market value are as follows:

 	As of June 30, 2012	 	As of December 31, 2011	
 	Carrying Amount	 	Fair Value	 	Carrying Amount	 	Fair Value	
 	(In millions)	
Assets:	 	 	 	 	 	 	 	
Notes receivable (a)	$	82	
 	 	$	82	
 	 	$	156	
 	 	$	161	
 	
Liabilities:	 	 	 	 	 	 	 	
Long-term debt, including current portion	10,556	
 	 	10,752	
 	 	9,729	
 	 	9,716	
 	
(a) June 30, 2012 excludes carrying amount of $109 million and fair value of $113 million related to Schkopau notes receivable reclassified to current assets held for sale.

The fair value of the Company's Level 1 publicly-traded long-term debt is based on quoted market prices. The fair value of the Company's Level 3 notes receivable, debt securities and non publicly-traded long-term debt are based on expected future cash flows discounted at market interest rates, or current interest rates for similar instruments with equivalent credit quality.

Recurring Fair Value Measurements

For cash and cash equivalents, funds deposited by counterparties, restricted cash, and cash collateral paid and received in support of energy risk management activities, the carrying amount approximates fair value because of the nature and short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy.

Derivative fair value measurements
 
The majority of NRG's contracts are exchange-traded contracts with readily available quoted market prices. A portion of NRG's contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations available through brokers or over-the-counter and on-line exchanges. For the majority of NRG markets, the Company receives quotes from multiple sources. To the extent that NRG receives multiple quotes, the Company's prices reflect the average of the bid-ask mid-point prices obtained from all sources that NRG believes provide the most liquid market for the commodity. If the Company receives one quote, then the mid-point of the bid-ask spread for that quote is used. The terms for which such price information is available vary by commodity, region and product. A significant portion of the fair value of the Company's derivative portfolio is based on price quotes from brokers in active markets who regularly facilitate those transactions and the Company believes such price quotes are executable. The Company does not use third party sources that derive price based on proprietary models or market surveys. The remainder of the assets and liabilities represent contracts for which external sources or observable market quotes are not available for the whole term or for certain delivery months or the contracts are retail and load following power contracts. These contracts are valued using various valuation techniques including but not limited to internal models that apply fundamental analysis of the market and corroboration with similar markets. Contracts valued with prices provided by models and other valuation techniques make up 19% of the total derivative assets and 16% of the total derivative liabilities.

The fair value of each contract is discounted using a risk free interest rate. In addition, the Company applies a credit reserve to reflect credit risk which is calculated based on published default probabilities. To the extent that NRG's net exposure under a specific master agreement is an asset, the Company uses the counterparty's default swap rate. If the exposure under a specific master agreement is a liability, the Company uses NRG's default swap rate. The credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume NRG's liabilities or that a market participant would be willing to pay for NRG's assets. As of June 30, 2012, the credit reserve resulted in a $9 million increase in fair value which is composed of a $6 million gain in Other Comprehensive Income, or OCI, and a $3 million gain in operating revenue and cost of operations. As of June 30, 2011, the credit reserve resulted in a $2 million decrease in fair value which is composed of a $2 million loss in operating revenue and cost of operations.

Concentration of Credit Risk

In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, to the Company's 2011 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company's contractual obligations. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, and retail customer credit risk through its retail load activities.

Counterparty Credit Risk

The Company monitors and manages counterparty credit risk through credit policies that include: (i) an established credit approval process; (ii) daily monitoring of counterparties' credit limits; (iii) the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting arrangements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risk surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty credit risk with a diversified portfolio of counterparties. The Company also has credit protection within various agreements to call on additional collateral support if and when necessary. Cash margin is collected and held at NRG to cover the credit risk of the counterparty until positions settle.

As of June 30, 2012, counterparty credit exposure to a portion of the Company's counterparties was $995 million and NRG held collateral (cash and letters of credit) against those positions of $141 million, resulting in a net exposure of $854 million. Counterparty credit exposure is valued through observable market quotes and discounted at the risk free rate. The following table highlights net counterparty credit exposure by industry sector and by counterparty credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for NRG with counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market and Normal Purchase Normal Sale, or NPNS, and non-derivative transactions. The exposure is shown net of collateral held, and includes amounts net of receivables or payables.

(b)	For non-rated counterparties, the majority are related to ISO and municipal public power entities, which are considered investment grade equivalent ratings based on NRG's internal credit ratings.	

NRG has counterparty credit risk exposure to certain counterparties representing more than 10% of total net exposure discussed above and the aggregate of such counterparties' exposure was $239 million. Approximately 87% of NRG's positions relating to this credit risk exposure roll-off by the end of 2013. Changes in hedge positions and market prices will affect credit exposure and counterparty concentration. Given the credit quality, diversification and term of the exposure in the portfolio, NRG does not anticipate a material impact on the Company's financial position or results of operations from nonperformance by any of NRG's counterparties.

Counterparty credit exposure described above excludes credit risk exposure under certain long term agreements, including California tolling agreements, South Central load obligations, and solar Power Purchase Agreements, or PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company valued these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. Based on these valuation techniques, as of June 30, 2012, credit risk exposure to these counterparties allocable to NRG's ownership interests was approximately $1.1 billion for the next five years. This amount excludes potential credit exposures for projects with long term PPAs that have not reached commercial operations. Many of these power contracts are with utilities or public power entities that have strong credit quality and specific public utility commission or other regulatory support. These factors significantly reduce the risk of loss.

Retail Customer Credit Risk

NRG is exposed to retail credit risk through the Company's retail electricity providers, which serve commercial, industrial and governmental/institutional, or C&I, customers and the residential and small business, or mass, market. Retail credit risk results when a customer fails to pay for services rendered. The losses may result from both nonpayment of customer accounts receivable and the loss of in-the-money forward value. NRG manages retail credit risk through the use of established credit policies that include monitoring of the portfolio, and the use of credit mitigation measures such as deposits or prepayment arrangements.

As of June 30, 2012, the Company's retail customer credit exposure was diversified across many customers and various industries, with a significant portion of the exposure with government entities.

Note 6 — Nuclear Decommissioning Trust Fund 

NRG's nuclear decommissioning trust fund assets, which are for its portion of the decommissioning of the South Texas Project, or STP Units 1 & 2, are comprised of securities classified as available-for-sale and recorded at fair value based on actively quoted market prices. NRG accounts for the nuclear decommissioning trust fund in accordance with ASC 980,  Regulated Operations , or ASC 980, because the Company's nuclear decommissioning activities are subject to approval by the Public Utility Commission of Texas, or PUCT, with regulated rates that are designed to recover all decommissioning costs and that can be charged to and collected from the ratepayers per PUCT mandate. Since the Company is in compliance with PUCT rules and regulations regarding decommissioning trusts and the cost of decommissioning is the responsibility of the Texas ratepayers, not NRG, all realized and unrealized gains or losses (including other-than-temporary impairments) related to the Nuclear Decommissioning Trust Fund are recorded to the Nuclear Decommissioning Trust Liability and are not included in net income or accumulated other comprehensive income, consistent with regulatory treatment.

The following table summarizes the aggregate fair values and unrealized gains and losses (including other-than-temporary impairments) for the securities held in the trust funds, as well as information about the contractual maturities of those securities.

Note 7 — Accounting for Derivative Instruments and Hedging Activities 

This footnote should be read in conjunction with the complete description under Note 6, Accounting for Derivative Instruments and Hedging Activities , to the Company's 2011 Form 10-K.

Energy-Related Commodities

As of June 30, 2012, NRG had energy-related derivative financial instruments extending through 2015, which are designated as cash flow hedges.

Interest Rate Swaps

NRG is exposed to changes in interest rates through the Company's issuance of variable and fixed rate debt. In order to manage the Company's interest rate risk, NRG enters into interest rate swap agreements. As of June 30, 2012, NRG had interest rate derivative instruments on recourse debt extending through 2013 and on non-recourse debt extending through 2029, the majority of which are designated as cash flow hedges.

Volumetric Underlying Derivative Transactions

The following table summarizes the net notional volume buy/(sell) of NRG's open derivative transactions broken out by commodity, excluding those derivatives that qualified for the NPNS exception as of June 30, 2012, and December 31, 2011. Option contracts are reflected using delta volume. Delta volume equals the notional volume of an option adjusted for the probability that the option will be in-the-money at its expiration date.

Amounts reclassified from accumulated OCI into income and amounts recognized in income from the ineffective portion of cash flow hedges are recorded to operating revenue for commodity contracts and interest expense for interest rate contracts.

Accounting guidelines require a high degree of correlation between the derivative and the hedged item throughout the period in order to qualify as a cash flow hedge. As of April 30, 2012, the Company's regression analysis for natural gas prices to ERCOT power prices, while positively correlated, did not meet the required threshold for cash flow hedge accounting for calendar year 2012. As a result, the Company de-designated its 2012 ERCOT cash flow hedges as of April 30, 2012, and prospectively marked these derivatives to market through the income statement.

Impact of Derivative Instruments on the Statement of Operations

Unrealized gains and losses associated with changes in the fair value of derivative instruments not accounted for as cash flow hedges and ineffectiveness of hedge derivatives are reflected in current period earnings.

The following table summarizes the pre-tax effects of economic hedges that have not been designated as cash flow hedges, ineffectiveness on cash flow hedges, and trading activity on the Company's statement of operations. The effect of commodity hedges is included within operating revenues and cost of operations and the effect of interest rate hedges is included in interest expense.

The reversal of loss positions acquired as part of the Reliant Energy and Green Mountain Energy acquisitions were valued based upon the forward prices on the acquisition dates. The roll off amounts were offset by realized losses at the settled prices and are reflected in the cost of operations during the same period.

For the six months ended June 30, 2012, the unrealized gain from open economic hedge positions was the result of an increase in ERCOT heat rates partially offset by decreases in forward natural gas, power and coal prices.

As of June 30, 2012, NRG had interest rate swaps designated as cash flow hedges on the Alpine solar project. The notional amount on the swaps exceeded the actual debt draws on the project. As such, NRG discontinued cash flow hedge accounting for these contracts and $4 million of loss previously deferred in OCI was recognized in earnings for the three and six months ended June 30, 2012.

For the six months ended June 30, 2011, the unrealized gain from open economic hedge positions was the result of an increase in value of forward purchases and sales of natural gas, electricity and fuel due to a decrease in forward power and gas prices.

Credit Risk Related Contingent Features

Certain of the Company's hedging agreements contain provisions that require the Company to post additional collateral if the counterparty determines that there has been deterioration in credit quality, generally termed “adequate assurance” under the agreements, or requires the Company to post additional collateral if there were a one notch downgrade in the Company's credit rating. The collateral required for contracts with adequate assurance clauses that are in a net liability position as of June 30, 2012, was $125 million. The collateral required for contracts with credit rating contingent features was $33 million. The Company is also a party to certain marginable agreements where NRG has a net liability position, but the counterparty has not called for the collateral due, which was approximately $94 million as of June 30, 2012.

See Note 5, Fair Value of Financial Instruments, to this Form 10-Q for discussion regarding concentration of credit risk.

NRG Repowering Holdings LLC

On January 25, 2012, NRG Repowering Holdings LLC, or NRG Repowering, terminated its revolving credit facility, repaid the $5 million then outstanding, and a supporting letter of credit issued by NRG was returned.

On January 25, 2012, NRG Repowering entered into a Credit and Reimbursement Agreement which provides for a $10 million working capital facility that can be used for general corporate purposes or to issue letters of credit, and an $80 million letter of credit facility. Interest on the letters of credit accrues at 3.5% and on loans under the working capital facility at the London Inter-Bank Offered Rate, or LIBOR, plus 3.50%. The facility is secured by NRG Repowering's investments in GenConn Energy LLC and South Trent Wind LLC, and matures January 25, 2015. As of June 30, 2012, NRG Repowering had issued a $10 million letter of credit under the working capital facility and $80 million in letters of credit under the letter of credit facility.

Alpine Financing
 
On March 16, 2012, NRG, through its wholly-owned subsidiary, NRG Solar Alpine LLC, or Alpine, entered into a credit agreement with a group of lenders, or the Alpine Financing Agreement, for a $166 million construction loan that will convert to a term loan upon completion of the project and a $68 million cash grant loan. The construction loan has an interest rate of LIBOR plus an applicable margin of 2.50% and the cash grant loan has an interest rate of LIBOR plus an applicable margin of 2.25%. The term loan has an interest rate of LIBOR plus an applicable margin of 2.50%, which escalates 0.25% on the fifth anniversary of the term conversion. The term loan, which is secured by all the assets of Alpine, matures on the 10 th  anniversary of the term conversion and amortizes based upon a predetermined schedule. The cash grant loan matures upon the earlier of the receipt of the cash grant or February 2013. The Alpine Financing Agreement also includes a letter of credit facility on behalf of Alpine of up to $37 million. Alpine pays an availability fee of 100% of the applicable margin on issued letters of credit. As of June 30, 2012, $2 million was outstanding under the construction loan, nothing was outstanding under the cash grant loans, and $18 million in letters of credit in support of the project were issued.
 
Also related to the Alpine Financing Agreement, on March 16, 2012, Alpine entered into a series of fixed for floating interest rate swaps for at least 85% of the outstanding term loan amount, intended to hedge the risks associated with floating interest rates. Alpine will pay its counterparty the equivalent of a 2.74% fixed interest payment on a predetermined notional value, and Alpine will receive quarterly the equivalent of a floating interest payment based on a one month LIBOR calculated on the same notional value through December 31, 2012 and based on a three month LIBOR from December 31, 2012 through the term loan maturity date. All interest rate swap payments by Alpine and its counterparty are made monthly through December 31, 2012, and quarterly thereafter and the LIBOR rate is determined in advance of each interest period. The notional amount of the swap, which became effective March 31, 2012, and matures on December 31, 2029, was $141 million as of June 30, 2012 and will increase and amortize in proportion to the loan.

Roadrunner Financing

On March 20, 2012, NRG, through its wholly-owned subsidiary, NRG Roadrunner LLC, or Roadrunner, received proceeds of $21 million under its cash grant application. These proceeds were used to repay Roadrunner's cash grant loan of $17 million plus accrued interest. The remaining cash was returned to NRG under the terms of the accounts agreement.

CVSR Financing
On March 9, 2012, NRG, through its wholly-owned subsidiary, High Plains Ranch II LLC, completed its first borrowing of $138 million under the CVSR Financing Agreement with the Federal Financing Bank. As of June 30, 2012, $277 million was outstanding under the loan.
NRG Energy, Inc. Tax-Exempt Bonds
On May 3, 2012, NRG executed a $54 million tax-exempt bond financing under Section 704 of the Heartland Disaster Tax Relief Act of 2008. The bonds were issued by the Fort Bend County Industrial Development Corporation and will be used for the construction of a peaking unit with one or more components of a carbon capture system at the W.A. Parish Generating Station in Thompsons, TX. The bonds initially bear weekly interest based on the Securities Industry and Financial Markets Association, or SIFMA, rate and have a maturity date of May 1, 2038. The proceeds drawn through June 30, 2012 were $1 million, and the remaining balance will be drawn over time as construction costs are paid.

Note 11 — Earnings Per Share 

Basic earnings per common share is computed by dividing net income less accumulated preferred stock dividends by the weighted average number of common shares outstanding. Shares issued and treasury shares repurchased during the year are weighted for the portion of the year that they were outstanding. Diluted earnings per share is computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares that were outstanding during the period.

The reconciliation of NRG's basic and diluted earnings per share is shown in the following table:

Note 13 — Income Taxes 
Effective Tax Rate
The income tax provision consisted of the following:

 	Three months ended June 30,	 	Six months ended June 30,	
(In millions except otherwise noted)	2012	 	2011	 	2012	 	2011	
Income/(loss) before income taxes	$	246	
 	 	$	(9	)	 	$	(80	)	 	$	(374	)	
Income tax benefit	(13	)	 	(630	)	 	(133	)	 	(735	)	
Effective tax rate	(5.3	)%	 	7,000.0	%	 	166.3	%	 	196.5	%	

For the three and six months ended June 30, 2012, NRG's overall effective tax rate was different than the statutory rate of 35% primarily due to the generation of ITCs from the Company's Agua Caliente solar project in Arizona and the settlement of the Green Mountain IRS audit as well as the reduction in the valuation allowance.

For the three and six months ended June 30, 2011, NRG's overall effective tax rate for both of these periods was different than the statutory rate of 35% primarily due to the recognition of previously uncertain tax benefits that were effectively settled upon audit in June 2011 and that were mainly composed of net operating losses of $536 million which had been classified as capital loss carryforwards for financial statement purposes. In addition, valuation allowance decreases of $40 million and $23 million for the three and six month periods, respectively, increased the effective tax rates.

Uncertain tax benefits

As of June 30, 2012, NRG has recorded a non-current tax liability of $65 million for uncertain tax benefits from positions taken on various state tax returns, including accrued interest. NRG has accrued interest related to these uncertain tax benefits of $1 million for the six months ended June 30, 2012, and has accrued $14 million of interest and penalties since adoption. The Company recognizes interest and penalties related to uncertain tax benefits in income tax expense.

The Company will continue to be under examination by various state and foreign tax jurisdictions for multiple years.

Tax Receivable and Payable

As of June 30, 2012, NRG recorded a current domestic tax receivable of $34 million, of which $18 million is related to property tax refunds as a result of the New York State Empire Zone program and $11 million relates to Federal income tax refunds for prior year tax return filings. As of June 30, 2012, NRG has a current tax payable of $13 million that represents a tax liability due for domestic state taxes of $11 million, as well as foreign taxes payable of $2 million. In addition, we have recorded a $52 million non-current asset for Empire Zone credits generated in 2010 through 2012 that are being deferred pursuant to New York State law.

Note 14 — Commitments and Contingencies 

Commitments
First Lien Structure
NRG has granted first liens to certain counterparties on substantially all of the Company's assets to reduce the amount of cash collateral and letters of credit that it would otherwise be required to post from time to time to support its obligations under out-of-the-money hedge agreements for forward sales of power or MWh equivalents. The Company's lien counterparties may have a claim on NRG's assets to the extent market prices exceed the hedged price. As of June 30, 2012, in aggregate, the hedge portfolio under the lien was in the money.

Contingencies
Set forth below is a description of the Company's material legal proceedings. The Company believes that it has valid defenses to these legal proceedings and intends to defend them vigorously. Pursuant to the requirements of ASC 450, Contingencies  and related guidance, NRG records reserves for estimated losses from contingencies when information available indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. In addition, legal costs are expensed as incurred. Management has assessed each of the following matters based on current information and made a judgment concerning its potential outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success. Unless specified below, the Company is unable to predict the outcome of these legal proceedings or reasonably estimate the scope or amount of any associated costs and potential liabilities. As additional information becomes available, management adjusts its assessment and estimates of such contingencies accordingly. Because litigation is subject to inherent uncertainties and unfavorable rulings or developments, it is possible that the ultimate resolution of the Company's liabilities and contingencies could be at amounts that are different from its currently recorded reserves and that such difference could be material.

In addition to the legal proceedings noted below, NRG and its subsidiaries are party to other litigation or legal proceedings arising in the ordinary course of business. In management's opinion, the disposition of these ordinary course matters will not materially adversely affect NRG's consolidated financial position, results of operations, or cash flows.

California Department of Water Resources
This matter concerns, among other contracts and other defendants, the California Department of Water Resources, or CDWR, and its wholesale power contract with subsidiaries of WCP (Generation) Holdings, Inc., or WCP. The case originated with a February 2002 complaint filed by the State of California alleging that many parties, including WCP subsidiaries, overcharged the State of California. For WCP, the alleged overcharges totaled approximately $940 million for 2001 and 2002. The complaint demanded that the Federal Energy Regulatory Commission, or FERC, abrogate the CDWR contract and sought refunds associated with revenues collected under the contract. In 2003, the FERC rejected this complaint, denied rehearing, and the case was appealed to the U.S. Court of Appeals for the Ninth Circuit where oral argument was held on December 8, 2004.

On December 19, 2006, the Ninth Circuit decided that in FERC's review of the contracts at issue, FERC could not rely on the  Mobile-Sierra  standard presumption of just and reasonable rates, where such contracts were not reviewed by the FERC with full knowledge of the then existing market conditions. WCP and others sought review by the U.S. Supreme Court. WCP's appeal was not selected, but instead held by the Supreme Court. In the appeal that was selected by the Supreme Court, on June 26, 2008, the Supreme Court ruled: (i) that the  Mobile-Sierra  public interest standard of review applied to contracts made under a seller's market-based rate authority; (ii) that the public interest “bar” required to set aside a contract remains a very high one to overcome; and (iii) that the  Mobile-Sierra  presumption of contract reasonableness applies when a contract is formed during a period of market dysfunction unless (a) such market conditions were caused by the illegal actions of one of the parties or (b) the contract negotiations were tainted by fraud or duress. In this related case, the U.S. Supreme Court affirmed the Ninth Circuit's decision agreeing that the case should be remanded to the FERC to clarify the FERC's 2003 reasoning regarding its rejection of the original complaint relating to the financial burdens under the contracts at issue and to alleged market manipulation at the time these contracts were formed. As a result, the U.S. Supreme Court then reversed and remanded the WCP CDWR case to the Ninth Circuit for treatment consistent with its June 26, 2008, decision in the related case. On October 20, 2008, the Ninth Circuit asked the parties in the remanded CDWR case, including WCP and the FERC, whether that Court should answer a question the U.S. Supreme Court did not address in its June 26, 2008, decision; whether the  Mobile-Sierra  doctrine applies to a third-party that was not a signatory to any of the wholesale power contracts, including the CDWR contract, at issue in that case. Without answering that reserved question, on December 4, 2008, the Ninth Circuit vacated its prior opinion and remanded the WCP CDWR case back to the FERC for proceedings consistent with the U.S. Supreme Court's June 26, 2008, decision. On December 15, 2008, WCP and the other seller-defendants filed with the FERC a Motion for Order Governing Proceedings on Remand. On January 14, 2009, the Public Utilities

30

Commission of the State of California, or CPUC, filed an Answer and Cross Motion for an Order Governing Procedures on Remand and on January 28, 2009, WCP and the other seller-defendants filed their reply. At this time, the FERC has not acted on remand.

On January 14, 2010, the U.S. Supreme Court issued its decision in an unrelated proceeding involving the Mobile-Sierra doctrine that will affect the standard of review applied to the CDWR contract on remand before the FERC. In  NRG Power Marketing v. Maine Public Utilities Commission , the Supreme Court held that the  Mobile-Sierra  presumption regarding the reasonableness of contract rates does not depend on the identity of the complainant who seeks a FERC investigation/refund.

As part of the 2006 acquisition of Dynegy's 50% ownership interest in WCP, WCP and NRG assumed responsibility for any risk of loss arising from this case, unless any such loss was deemed to have resulted from certain acts of gross negligence or willful misconduct on the part of Dynegy, in which case any such loss would be shared equally between WCP and Dynegy.

On March 22, 2012, NRG reached an agreement in principle with the CPUC to settle and resolve this matter, including all related claims, on behalf of NRG and on behalf of Dynegy. The agreement in principle was announced by the Company on March 23, 2012, as well as by the CPUC and by the California Governor's Office. The documented agreement was executed and submitted to FERC on April 27, 2012 for its approval. The settlement agreement contains three material elements to be fulfilled over a four to six year period, depending upon several factors. First, the settlement agreement includes a $20 million cash payment due 30 days after FERC approval. Second, it includes the construction and operation of a fee-based charging network, to be owned and operated by NRG subsidiary, eVgo, which will consist of at least 200 publicly available fast-charging electric vehicle stations installed at locations across California. Last, it calls for the wiring and associated work required to improve at least 10,000 individual parking spaces to allow for the charging of electric vehicles in at least 1,000 multi-family complexes, worksites, and public interest locations such as community colleges, public universities, and public or non-profit hospitals. Although these improved newly wired parking spaces will continue to be owned by the local property owner, eVgo will have an 18-month exclusive right to obtain customers from these locations starting from the date of each completed installation. The expected $20 million cash payment was accrued and expensed in the statement of operations for the three months ended March 31, 2012. In addition, the Company expects to spend approximately $100 million over the next four to six year period, during which the Company will fulfill the other elements of the settlement, and will capitalize a substantial majority of the costs as property, plant and equipment, representing the costs to construct the charging network and the wiring, which will be productive assets. The Company will expense the costs to operate the assets as incurred. FERC approval is expected in the third quarter of 2012. On May 24, 2012, ECOtality, Inc. filed a lawsuit against the CPUC challenging the settlement.

Louisiana Generating, LLC

On February 11, 2009, the U.S. Department of Justice, or U.S. DOJ, acting at the request of the U.S. Environmental Protection Agency, or U.S. EPA, commenced a lawsuit against Louisiana Generating, LLC, or LaGen, in federal district court in the Middle District of Louisiana alleging violations of the Clean Air Act, or CAA, at the Big Cajun II power plant. This is the same matter for which Notices of Violation, or NOVs, were issued to LaGen on February 15, 2005, and on December 8, 2006. Specifically, it is alleged that in the late 1990's, several years prior to NRG's acquisition of the Big Cajun II power plant from the Cajun Electric bankruptcy and several years prior to the NRG bankruptcy, modifications were made to Big Cajun II Units 1 and 2 by the prior owners without appropriate or adequate permits and without installing and employing the best available control technology, or BACT, to control emissions of nitrogen oxides and/or sulfur dioxides. The relief sought in the complaint includes a request for an injunction to: (i) preclude the operation of Units 1 and 2 except in accordance with the CAA; (ii) order the installation of BACT on Units 1 and 2 for each pollutant subject to regulation under the CAA; (iii) obtain all necessary permits for Units 1 and 2; (iv) order the surrender of emission allowances or credits; (v) conduct audits to determine if any additional modifications have been made which would require compliance with the CAA's Prevention of Significant Deterioration program; (vi) award to the U.S. DOJ its costs in prosecuting this litigation; and (vii) assess civil penalties of up to $27,500 per day for each CAA violation found to have occurred between January 31, 1997, and March 15, 2004, up to $32,500 for each CAA violation found to have occurred between March 15, 2004, and January 12, 2009, and up to $37,500 for each CAA violation found to have occurred after January 12, 2009.

On April 27, 2009, LaGen filed an objection in the Cajun Electric Cooperative Power, Inc.'s bankruptcy proceeding in the U.S. Bankruptcy Court for the Middle District of Louisiana to seek to prevent the bankruptcy from closing. LaGen also filed a complaint, or adversary proceeding, in the same bankruptcy proceeding, seeking a judgment that: (i) it did not assume liability from Cajun Electric for any claims or other liabilities under environmental laws with respect to Big Cajun II that arose, or are based on activities that were undertaken, prior to the closing date of the acquisition; (ii) it is not otherwise the successor to Cajun Electric with respect to environmental liabilities arising prior to the acquisition; and (iii) Cajun Electric and/or the Bankruptcy Trustee are exclusively liable for any of the violations alleged in the February 11, 2009 lawsuit to the extent that such claims are determined to have merit. On April 15, 2010, the bankruptcy court signed an order granting LaGen's stipulation of voluntary dismissal without prejudice of the adversary proceeding. The bankruptcy proceeding has since closed.

31

On August 24, 2009, LaGen filed a motion to dismiss this lawsuit, and on September 25, 2009, the U.S. DOJ filed its opposition to the motion. Thereafter, on February 18, 2010, the Louisiana Department of Environmental Quality, or LDEQ, filed a motion to intervene in the above lawsuit and a complaint against LaGen for alleged violations of Louisiana's Prevention of Significant Deterioration, or PSD, regulations and Louisiana's Title V operating permit program. LDEQ seeks substantially similar relief to that requested by the U.S. DOJ. On February 19, 2010, the district court granted LDEQ's motion to intervene. On April 26, 2010, LaGen filed a motion to dismiss the LDEQ complaint. On July 21, 2010, the motions to dismiss the U.S. DOJ and LDEQ complaints were argued to the district court. On August 20, 2010, the parties submitted proposed findings of fact and conclusions of law, and thereafter submitted additional briefing on emerging jurisprudence from other jurisdictions touching on the issues at stake in the lawsuit. Having not ruled on the motion to dismiss, on February 4, 2011, LaGen filed motions for summary judgment requesting that the court dismiss all of the U.S. DOJ's claims. Also on February 4, 2011, the U.S. DOJ filed three motions for partial summary judgment. Additional summary judgment briefing was filed by the parties on April 4, 2011. On November 2, 2011, the court heard oral argument on three motions for summary judgment. On December 1, 2011, the court issued an order denying two of LaGen's motions for summary judgment addressing potential legal defenses to CAA liability. In the same order, the court also granted, in part, the U.S. DOJ's motion for summary judgment on its successor liability theory. The court held that LaGen could be found to have assumed liability for alleged PSD violations under the terms of the agreement through which LaGen acquired Big Cajun II in 2000, but ruled that the facts necessary to determine whether any such liabilities were actually assumed must be determined at a liability-phase trial, if necessary. In its December 1, 2011 decision, the court also ruled that any potential civil penalties would not be available for the periods prior to the five year period preceding the filing of the lawsuit on February 11, 2009.

Three additional motions for summary judgment and multiple motions in limine, including motions that could result in dismissal of the government's claims before trial if resolved in LaGen's favor, remain pending before the court; some of these motions were argued on March 21 and 22, 2012. On May 14, 2012, the court denied the motions argued on March 21 and 22, 2012. On January 17, 2012, LaGen filed a demand for a jury trial. On January 20, 2012, the court scheduled a liability-phase trial for October 15, 2012, should the case proceed to that stage, and a remedy-phase trial set to occur at a later date to be determined in the event of an adverse decision in a liability-phase trial. Because of the inherent uncertainty of litigation, including the fact that no determination of liability has yet been made by the court, NRG cannot predict the impact, at this time, that this matter may have on the Company's business, results of operations, financial position, or cash flows.

In a related matter, soon after the filing of the above referenced U.S. DOJ lawsuit, LaGen sought insurance coverage from its insurance carrier, Illinois Union Insurance Company, or ILU. ILU denied coverage and thereafter LaGen filed a lawsuit (which was consolidated with a prior suit filed by ILU) seeking a declaration that ILU must provide coverage to LaGen for the defense costs incurred in defending the U.S. DOJ lawsuit.  LaGen and ILU both filed motions for summary judgment and on January 30, 2012, the court issued an order granting LaGen's motion finding that ILU has a duty to defend LaGen. The trial court certified the summary judgment for immediate interlocutory appeal, and on May 25, 2012, ILU filed a petition with the U.S. Circuit Court of Appeals for the Fifth Circuit seeking to appeal the trial court's summary judgment ruling. ILU filed a related notice of appeal with the trial court on June 14, 2012. On July 23, 2012, the trial court granted ILU's related notice of appeal thereby certifying the matter for appeal to the U.S. Circuit Court of Appeals for the Fifth Circuit.

Energy Plus Holdings, LLC Purported Class Actions

Energy Plus Holdings, LLC, or Energy Plus, is a defendant in three purported class action lawsuits, one in New York and two in New Jersey (Energy Plus Natural Gas LP is a defendant in the two New Jersey lawsuits and NRG Energy, Inc. is a defendant in one of the New Jersey lawsuits). The plaintiffs in those lawsuits generally allege that Energy Plus misrepresents that its rates are competitive in the market; fails to disclose that its rates are substantially higher than those in the market and that Energy Plus has engaged in deceptive practices in its marketing of energy services. Plaintiffs generally seek that these matters be certified as class actions, with treble damages, interest, costs, attorneys' fees, and any other relief that the court deems just and proper. We believe that these allegations are without merit and we are defending against these claims.

In addition, on July 26, 2012, the Connecticut Attorney General and Office of Consumer Counsel filed a petition with the Connecticut Public Utilities Regulatory Authority seeking to investigate Energy Plus' marketing practices. On August 7, 2012, Energy Plus Holdings LLC and Energy Plus Natural Gas LLC received a subpoena from the State of New York Office of Attorney General which generally seeks information and business records related to Energy Plus' sales, marketing and business practices.

Purported Class Actions related to July 22, 2012 Announcement of NRG/GenOn Merger Agreement

NRG Energy, Inc. has been named as a defendant in eight purported class actions pending in Texas and Delaware, related to its announcement of its agreement to acquire all outstanding shares of GenOn. The plaintiffs generally allege breach of fiduciary duties, as well as conspiracy, aiding and abetting breaches of fiduciary duties. Plaintiffs are generally seeking to: be certified as a class; enjoin the merger; direct the defendant to exercise their fiduciary duties; rescind the acquisition and be awarded attorneys' fees costs and other relief that the court deems appropriate. We believe that these allegations are without merit and we intend to cooperate with GenOn in the defense of these claims.

Note 15 — Regulatory Matters 

NRG operates in a highly regulated industry and is subject to regulation by various federal and state agencies. As such, NRG is affected by regulatory developments at both the federal and state levels and in the regions in which NRG operates. In addition, NRG is subject to the market rules, procedures, and protocols of the various Independent System Operator, or ISO, markets in which NRG participates. These power markets are subject to ongoing legislative and regulatory changes that may impact NRG's wholesale and retail businesses.

In addition to the regulatory proceedings noted below, NRG and its subsidiaries are a party to other regulatory proceedings arising in the ordinary course of business or have other regulatory exposure. In management's opinion, the disposition of these ordinary course matters will not materially adversely affect NRG's consolidated financial position, results of operations, or cash flows.

California — On May 4, 2010, in Southern California Edison Company v. FERC, the U.S. Court of Appeals for the D.C. Circuit vacated the FERC's acceptance of station power rules for the California Independent System Operator, or CAISO, market, and remanded the case for further proceedings at the FERC. On August 30, 2010, the FERC issued an Order on Remand effectively disclaiming jurisdiction over how the states impose retail station power charges. Due to reservation-of-rights language in the California utilities' state-jurisdictional station power tariffs, the FERC's ruling arguably requires California generators to pay state-imposed retail charges back to the date of enrollment by the facilities in the CAISO's station period program (February 1, 2009, for the Company's Encina and El Segundo facilities; March 1, 2009, for the Company's Long Beach facility). On February 28, 2011, the FERC issued an order denying rehearing. The Company, together with other generators, filed an appeal in the D.C. Circuit which is awaiting oral argument. On November 18, 2011, Southern California Edison Company filed with the CPUC, seeking authorization to begin charging generators station power charges, and to assess such charges retroactively, which the Company and other generators have challenged. The Company has filed a protest with the CPUC objecting to Southern California Edison's filing. That protest remains pending. The Company believes it has established an appropriate reserve.

Retail (Replacement Reserve)—On November 14, 2006, Constellation Energy Commodities Group, or Constellation, filed a complaint with the PUCT alleging that ERCOT misapplied the Replacement Reserve Settlement, or RPRS, Formula contained in the ERCOT protocols from April 10, 2006, through September 27, 2006.  Specifically, Constellation disputed approximately $4 million in under-scheduling charges for capacity insufficiency asserting that ERCOT applied the wrong protocol.  Retail Electric Providers, or REPS, other market participants, ERCOT, and PUCT staff opposed Constellation's complaint.  On January 25, 2008, the PUCT entered an order finding that ERCOT correctly settled the capacity insufficiency charges for the disputed dates in accordance with ERCOT protocols and denied Constellation's complaint.  On April 9, 2008, Constellation appealed the PUCT order to the Civil District Court of Travis County, Texas and on June 19, 2009, the court issued a judgment reversing the PUCT order, finding that the ERCOT protocols were in irreconcilable conflict with each other.  Under the PUCT ordered formula, Qualified Scheduling Entities, or QSEs, who under-scheduled capacity within any of ERCOT's four congestion zones were assessed under-scheduling charges which defrayed the costs incurred by ERCOT for RPRS that would otherwise be spread among all load-serving QSEs.  Under the Court's decision, all RPRS costs would be assigned to all load-serving QSEs based upon their load ratio share without assessing any separate charge to those QSEs who under-scheduled capacity.  If under-scheduling charges for capacity insufficient QSEs were not used to defray RPRS costs, REPS's share of the total RPRS costs allocated to QSEs would increase.  On July 20, 2009, REPS filed an appeal to the Third Court of Appeals in Travis County, Texas, thereby staying the effect of the trial court's decision.  On October 6, 2010, the parties argued the appeal before the Court of Appeals for the Third District in Austin, Texas.  On September 28, 2011, the Court of Appeals reversed the trial court decision, reinstating the PUCT's order, consistent with REPS' position.  On January 13, 2012, Constellation filed a Petition for Review in the Supreme Court of Texas asking the Court to grant review of and reverse the Court of Appeals decision. The Texas Supreme Court has requested that briefs on the merits be filed before deciding whether to hear the Petition for Review.  Constellation's brief is due September 5, 2012.  Responses to Constellation's brief are due September 25, 2012.

Retail (Midwest ISO SECA) — Green Mountain Energy previously provided competitive retail energy supply in the Midwest ISO region during the relevant period of January 1, 2002, to December 31, 2005. By order dated November 18, 2004, FERC eliminated certain regional through-and-out transmission rates charged by transmission owners in the regional electric grids operated by the Midwest Independent Transmission Systems Operator, Inc., or MISO, and PJM Interconnection, L.L.C., or PJM. In order to temporarily compensate the transmission owners for revenue lost as a result of the elimination of the through-and-out transmission rates, the FERC also ordered MISO, PJM and their respective transmission owners to provide for the recovery of certain Seams Elimination Charge/Cost Adjustments/Assignments, or SECA, charges effective December 1, 2004, through March 31, 2006, based on usage during 2002 and 2003. The tariff amendments filed by MISO and the MISO transmission owners allocated certain SECA charges to various zones and sub-zones within MISO, including a sub-zone called the Green Mountain Energy Company Sub-zone. Over the last several years, there has been extensive litigation before the FERC relating to these charges, seeking, among other things, to recover monies from Green Mountain Energy, and before the federal appellate courts. Green Mountain Energy has not paid any asserted SECA charges.

On May 21, 2010, the FERC issued two orders. In its Order on Rehearing, the FERC denied all requests for rehearing of its past orders directing and accepting the SECA compliance filings of MISO, PJM, and the transmission owners. In its Order on Initial Decision, FERC: (1) affirmed an order by the Administrative Law Judge granting Green Mountain Energy partial summary judgment and holding Green Mountain Energy not liable for SECA charges for January  -  March 2006; and (2) reversed an August 2006 determination by the Administrative Law Judge that Green Mountain Energy could be held directly liable for some amount of SECA charges. The Order on Initial Decision also directed that the two Regional Transmission Organizations, or RTOs, and their respective transmission owners submit further compliance filings, which were filed on August 19, 2010. The FERC has not yet ruled on those compliance filings.

With regard to the SECA charges that had been invoiced to Green Mountain Energy, the FERC determined that most of those charges, approximately $22 million plus interest, were owed not by Green Mountain Energy but rather by BP Energy —  one of Green Mountain Energy's suppliers during the period at issue. On August 19, 2010, the transmission owners and MISO made compliance filings in accordance with the FERC's Orders allocating SECA charges to a BP Energy Sub-zone, and making no allocation to a Green Mountain Energy sub-zone. BP Energy has not asserted any contractual claims against Green Mountain Energy. The Company believes it has established an appropriate reserve.

On September 30, 2011, the FERC issued orders denying BP Energy's request for rehearing of the May 2010 Order on Rehearing, denying all requests for rehearing of the Order on Initial Decision, and again determined that SECA charges were not owed by Green Mountain Energy. Numerous parties have sought judicial review of the FERC's Order on Initial Decision, and BP Energy has sought judicial review of the May 2010 Order on Rehearing. These appeals have been consolidated with previous appeals of orders relating to SECA before the U.S. Court of Appeals for the DC Circuit. Green Mountain Energy has been granted intervenor status in the consolidated appeals.

On May 10, 2012, the Court issued an order setting out a briefing schedule which provided for the submittal of petitioners' briefs on July 17, 2012. On July 5, 2012, BP Energy and three PJM transmission owners filed a motion asking the Court to suspend the briefing schedule. The movants stated that respondent FERC and all other petitioners either supported or did not oppose the motion. The movants further stated that they had reached a settlement resolving all SECA claims involving BP Energy, were filing the settlement agreement with the FERC that day, and desired a suspension of the briefing schedule to enable the FERC to act on the proposed settlement. The movants did in fact file the settlement agreement at the FERC that day. The agreement provided for BP Energy to pay a total of approximately $24 million to the three transmission owners signing the agreement, with another $1 million offered to the remaining PJM transmission owners, should they choose to join the settlement. On July 10, 2012, the D.C. Circuit issued an order granting the motion to vacate the briefing schedule and directing the remaining parties to submit a motion to govern further proceedings by September 17, 2012.

Note 16 — Environmental Matters 

NRG is subject to a wide range of environmental regulations across a broad number of jurisdictions in the development, ownership, construction and operation of domestic and international projects. These laws and regulations generally require that governmental permits and approvals be obtained before construction and during operation of power plants. Environmental regulations have become increasingly stringent and NRG expects this trend to continue. The electric generation industry is likely to face new requirements to address various emissions, including greenhouse gases, as well as combustion byproducts and water use. In general, future laws and regulations are expected to require the addition of emission controls or other environmental quality equipment or the imposition of certain restrictions on the operations of the Company's facilities. NRG expects that future liability under, or compliance with, environmental requirements could have a material effect on the Company's operations or competitive position.

Environmental Capital Expenditures
 
Based on current rules, technology and plans as well as preliminary plans based on proposed rules, NRG has estimated that environmental capital expenditures from 2012 through 2016 to meet NRG's regulatory environmental commitments will be approximately $553 million. These costs are primarily associated with mercury controls to satisfy the Mercury and Air Toxics Standards, or MATS, on the Company's Big Cajun II, W.A. Parish and Limestone facilities and a number of intake modification projects across the fleet under state or proposed federal 316(b) rules. NRG continues to explore cost effective compliance alternatives to reduce costs. While this estimate reflects anticipated schedules and controls related to the proposed 316(b) Rule, the full impact on the scope and timing of environmental retrofits from any new or revised regulations cannot be determined until these rules are final and any legal challenges are reviewed. However, NRG believes it is positioned to meet more stringent environmental regulations through its planned capital expenditures, existing controls, and increasing generation from renewable resources.
 
NRG's current contracts with the Company's rural electric cooperative customers in the South Central region allow for recovery of a portion of the region's environmental capital costs incurred as the result of complying with any change in environmental law. Cost recoveries begin once the environmental equipment becomes operational and include a capital return. The actual recoveries will depend, among other things, on the timing of the completion of the capital projects and the remaining duration of the contracts.

Northeast Region
 
In January 2006, NRG's Indian River Operations, Inc. received a letter of informal notification from Delaware Department of Natural Resources and Environmental Control, or DNREC, stating that it may be a potentially responsible party with respect to Burton Island Old Ash Landfill, a historic captive landfill located at the Indian River facility. On October 1, 2007, NRG signed an agreement with DNREC to investigate the site through the Voluntary Clean-up Program. On February 4, 2008, DNREC issued findings that no further action is required in relation to surface water and that a previously planned shoreline stabilization project would satisfactorily address shoreline erosion. The landfill itself will require a further Remedial Investigation and Feasibility Study to determine the type and scope of any additional work required. Until the Remedial Investigation and Feasibility Study is approved, the Company is unable to predict the impact of any required remediation. On May 29, 2008, DNREC requested that NRG's Indian River Operations, Inc. participate in the development and performance of a Natural Resource Damage Assessment, or NRDA, at the Burton Island Old Ash Landfill. NRG is currently working with DNREC and other trustees to close out the assessment phase.
  
South Central Region
 
On February 11, 2009, the U.S. DOJ acting at the request of the U.S. EPA commenced a lawsuit against LaGen in federal district court in the Middle District of Louisiana alleging violations of the CAA at the Big Cajun II power plant. This is the same matter for which NOVs were issued to LaGen on February 15, 2005, and on December 8, 2006. Further discussion on this matter can be found in Note 14,  Commitments and Contingencies  -  Louisiana Generating, LLC.

Executive Summary

Introduction and Overview

NRG Energy, Inc., or NRG or the Company, is an integrated wholesale power generation and retail electricity company that aspires to be a leader in the way the industry and consumers think about, use, produce and deliver energy and energy services in major competitive power markets in the United States. First, NRG is a wholesale power generator engaged in the ownership and operation of power generation facilities; the trading of energy, capacity and related products; and the transacting in and trading of fuel and transportation services. Second, NRG is a retail electricity company engaged in the supply of electricity, energy services, and cleaner energy products to retail electricity customers in deregulated markets through its Retail businesses. Finally, NRG is focused on the deployment and commercialization of potential disruptive technologies, like electric vehicles, Distributed Solar and smart meter technology, which have the potential to change the nature of the power supply industry.

NRG's Business Strategy

NRG's business strategy is intended to maximize stockholder value through the production and sale of safe, reliable and affordable power to its customers in the markets served by the Company, while aggressively positioning the Company to meet the market's increasing demand for sustainable and low carbon energy solutions. This strategy is designed to enhance the Company's core business of competitive power generation and mitigate the risk of declining power prices. The Company expects to become a leading provider of sustainable energy solutions that promotes national energy security, while utilizing the Company's Retail businesses to complement and advance both initiatives.

The Company's core business is focused on: (i) excellence in safety and operating performance of its existing assets; (ii) serving the energy needs of end-use residential, commercial and industrial customers in the Company's core markets with a retail energy product that is differentiated either by premium service (Reliant), sustainability (Green Mountain Energy) or loyalty/affinity programs (Energy Plus); (iii) optimal hedging of baseload generation and retail load operations, while retaining optionality on the Company's peaking facilities; (iv) repowering of power generation assets at premium sites; (v) investment in, and deployment of, alternative energy technologies both in its wholesale and, particularly, in and around its Retail businesses and their customers; (vi) pursuing selective acquisitions, joint ventures, divestitures and investments; and (vii) engaging in a proactive capital allocation plan focused on achieving the regular return of and on stockholder capital within the dictates of prudent balance sheet management.

Moreover, the Company believes that the American energy industry is going to be increasingly impacted by the long-term societal trend towards sustainability which is both generational and irreversible. This trend is further influenced by the information technology-driven revolution, which has enabled greater and easier personal choice in other sectors of the consumer economy and will do the same in the American energy sector over the years to come. As a result, energy consumers will have increasing personal control over from whom they buy their energy, how that energy is generated and used and what environmental impact these individual choices will have. The Company's initiatives in this area of future growth are focused on: (i) renewables, with a concentration in solar development; (ii) electric vehicle ecosystems; (iii) customer-facing energy products and services including smart grid services, nationwide retail green electricity, unique retail sales channels involving loyalty and affinity programs and custom design; and (iv) the construction of other forms of on-site clean power generation. The Company's advances in each of these areas are driven by select acquisitions, joint ventures, and investments that are more fully described in Item 1,  Business - New and On-going Company Initiatives and Development Projects  of the Company's 2011 Form 10-K, and this Form 10-Q.

Pending Acquisition

On July 20, 2012, the Company entered into an agreement, or the Merger Agreement, to acquire GenOn Energy, Inc., or GenOn.  GenOn, a generator of wholesale electricity, has baseload, intermediate and peaking power generation facilities using coal, natural gas and oil, totaling approximately 22,700 MW.  The Company will issue, as consideration for the acquisition, 0.1216 shares of NRG common stock for each outstanding share of GenOn, including restricted stock units outstanding, on the acquisition date, except for fractional shares which will be paid in cash.  The acquisition is expected to close by the first quarter of 2013.

The Merger Agreement contains customary representations, warranties and covenants of NRG and GenOn, including, among others, covenants (a) to conduct their respective businesses in the ordinary course during the interim period between the execution of the Merger Agreement and completion of the merger, (b) not to engage in certain material transactions during the interim period except with the consent of the other party, (c) that NRG will convene and hold a meeting of its stockholders to consider and vote upon the approval of the issuance of NRG common stock in the merger and the approval and adoption of the charter amendment to allow the size of NRG's Board of Directors to be increased to16 members in connection with the closing, (d) that GenOn will convene and hold a meeting of its stockholders to consider and vote upon the adoption of the Merger Agreement, and (e) that the parties use their respective reasonable best efforts to take all actions necessary to obtain all governmental and regulatory approvals and consents.

51

The combined company, which will retain the name NRG Energy, Inc., will become the largest competitive power generation company in the United States with approximately 47,000 MW of fossil fuel, nuclear, solar and wind capacity across the merit order in major competitive energy markets across the United States. In 2011, the combined fleet generated approximately 105 terawatt-hours of electricity. Expected synergies include cost and operational efficiency synergies, interest savings, reduced liquidity and collateral requirements, and a greater operational scale, which will enhance the combined company's ability to revitalize its generation fleet and optimize portfolio value.

Environmental Matters

Environmental Regulatory Landscape

In 2011, a number of U.S. EPA air regulations were finalized providing more clarity to the impact on electric generating units. A number of regulations with the potential for impact are still in development or under review by the U.S. EPA: New Source Performance Standards, or NSPS, for Greenhouse Gases, or GHGs, National Ambient Air Quality Standards, or NAAQS, revisions, coal combustion byproducts, and once-through cooling. While most of these regulations have been considered for some time, the outcomes and any resulting impact on NRG cannot be fully predicted until the rules are finalized. The timing and stringency of these regulations will contribute to a framework for the retrofit of existing fossil plants and deployment of new, cleaner technologies in the next decade. See discussion below for more detail.

Air — The U.S. EPA released the Cross-State Air Pollution Rule, or CSAPR, on July 7, 2011, with additional proposed updates on October 6, 2011. CSAPR was scheduled to replace the Clean Air Interstate Rule, or CAIR, on January 1, 2012. It was designed to bring states into attainment with PM 2.5 and ozone NAAQS, reducing SO 2  and NO x  emissions from power plants. The U.S. Court of Appeals for the District of Columbia Circuit stayed the rule on December 30, 2011, pending resolution of the numerous petitions for judicial review and leaving CAIR in effect during the stay. On February 8, 2012, the U.S. EPA finalized the incremental state allowance budgets and resulting company allocations proposed in October 2011 and added additional allowance in certain states under the Direct Final Rule. NRG benefited from both rounds of allocation increases. The Company is unable to predict the final outcome of the court proceeding. There is no material impact to NRG related to the stay.

On February 16, 2012, the U.S. EPA finalized MATS, to control emissions of hazardous air pollutants from coal and oil fired electric generating units. Requirements include meeting the standards for mercury, acid gases, and certain metals (such as particulate matter) by April 16, 2015 on a plant wide basis with the potential for a one year extension. In April 2012, the rule was challenged on a number of issues by some states and industrial representatives. The appeal will be heard before the D.C. Circuit. NRG does not anticipate any plant impairments or capital expenditures beyond the current environmental capital expenditures schedule.

The U.S. EPA published the proposed New Source Performance Standards, or NSPS, for GHGs on April 13, 2012. The new standard, 1,000 tons of CO 2  per MWh gross, applies only to new electric generating units greater than 25 MW and provides averaging options for new units expected to install carbon capture. An exclusion for existing units minimizes the impact to NRG's coal plants.

On July 3, 2012, the EPA finalized the continued use of modified trigger levels through 2016 for GHG emissions in the Tailoring Rule. This rule maintains the current level at which projects must be permitted. While most repowering projects still trigger the permitting, the higher limit provides relief to smaller projects like the installation of back-end controls to meet other regulations.

Regulatory Matters

As operators of power plants and participants in wholesale and retail energy markets, certain NRG entities are subject to regulation by various federal and state government agencies. These include the Commodities Futures Trading Commission, or CFTC, FERC, Nuclear Regulatory Commission, or NRC, and PUCT, as well as other public utility commissions in certain states where NRG's generating, thermal, or distributed generation assets are located. In addition, NRG is subject to the market rules, procedures and protocols of the various ISO markets in which it participates. Likewise, certain NRG entities participating in the retail markets are subject to rules and regulations established by the states in which NRG entities are licensed to sell at retail. NRG must also comply with the mandatory reliability requirements imposed by the North American Electric Reliability Corporation, or NERC, and the regional reliability entities in the regions where the Company operates.

NRG's operations within the ERCOT footprint are not subject to rate regulation by the FERC, as they are deemed to operate solely within the ERCOT market and not in interstate commerce. These operations are subject to regulation by PUCT, as well as to regulation by the NRC with respect to the Company's ownership interest in STP.

Texas Region

NRC Task Force Report — On March 11, 2012, the NRC issued Tier 1 requirements in response to the Near-Term Task Force report. Specifically, the NRC issued rules governing installation of spent fuel pool instrumentation and established mitigation strategies for beyond-design-basis external events. Additionally, the NRC issued requests for information regarding the re-evaluation of seismic and flooding hazards and the development of staffing strategies necessary for responding to an extended station blackout multi-unit event. The Company has submitted the required contingency plans and the NRC accepted the proposals. The Company anticipates being able to comply in a timely manner with all announced requirements.

ERCOT System-Wide Offer Caps —At its June 26, 2012, meeting, the PUCT approved an amendment to raise the ERCOT system-wide energy and ancillary service offer cap from $3,000 to $4,500 per MWh beginning August 1, 2012.  A second proposed PUCT rule change is pending that would raise the system-wide offer cap on June 1, 2013 to $5,000 per MWh, escalating to $9,000 per MWh on June 1, 2015. The PUCT is expected to take action on this second proposed rule at its September 28, 2012 meeting.  The ERCOT ISO is expected to shift the Power Balance Penalty Curve, or PBPC, to match these offer cap levels.  An increase in the cap on electricity prices could have a material impact on NRG's retail and wholesale operations. This is expected to be overall positive to NRG as it will potentially result in increased wholesale revenues. 

Over the past several months, ERCOT has implemented a number of measures intended to ensure that real-time energy prices accurately reflect supply scarcity conditions. Specific changes include requiring that energy from reliability services (such as responsive reserves and reliability unit commitments) be offered at the system-wide offer cap, implementing floor prices during the deployment of non-spinning reserve services, and shifting 500 MWs of non-spinning reserves to responsive reserves procurement by the ISO.

On June 1, 2012, the Brattle Group issued an ERCOT sponsored report on resource adequacy. The Brattle Report recommends the adoption of a $9,000 ERCOT system-wide offer cap, along with other broader market design recommendations designed to incent investment in ERCOT generation.  The PUCT has initiated a new proceeding to evaluate the recommendations.

ERCOT Voluntary Mitigation Plan —On June 18, 2012, NRG submitted a Voluntary Mitigation Plan, or VMP, which had been agreed to by PUCT Staff, and the ERCOT Independent Market Monitor. The VMP establishes a safe harbor for energy offers from NRG's units in ERCOT's real-time market.  The VMP was approved by the PUCT on July 13, 2012. 

Northeast Region

New England
Forward Capacity Market — On January 19, 2012, the FERC issued an order largely denying rehearing of its prior decision addressing proposed amendments submitted by ISO New England Inc., or ISO-NE, to its Forward Capacity Market, or FCM, design, as well as two pending complaints. On March 16, 2012, the Company and other generators with interests in New England appealed the FERC's decision to the DC Circuit Court of Appeals. Briefing is currently underway.

New York
New Financial Reporting Rules in New York —On March 23, 2012, the New York Public Service Commission, or NYPSC, issued an order addressing its policy of applying “lightened” regulation to wholesale generators. The order proposed to subject wholesale generators, which would include NRG entities operating in New York, to more stringent financial reporting rules, including a requirement for generators to make an annual submission of “receipts and expenditures” to the NYPSC. The NYPSC extended the date for comments on the proposed financial reporting forms to July 30, 2012.

Dunkirk Power LLC Reliability Service —On March 14, 2012, Dunkirk Power LLC, or Dunkirk Power, filed a notice with the New York Department of Public Service, or DPS, of its intent to mothball the Dunkirk Station no later than September 10, 2012.  The effects of the mothball on electric system reliability were reviewed by Niagara Mohawk Power Corporation, d/b/a National Grid, or NG.  As a result of those studies, NG determined that the mothball of the Dunkirk Station would have a negative impact on the reliability of the New York transmission system and that portions of the Dunkirk Station may be retained for reliability purposes via a non-market compensation arrangement.  On July 12, 2012, Dunkirk Power filed a Reliability Must Run, or RMR, agreement, with the FERC. On July 20, 2012, NG and Dunkirk Power agreed on the material terms for a bilateral reliability support services agreement and submitted those terms to the NYPSC for rate recovery in NG's rates. The parties have requested that the NYPSC approve the reliability services agreement at its next open meeting, currently scheduled for August 16, 2012. Pending approval of the reliability services agreement, Dunkirk Power has requested that the FERC defer consideration of its RMR agreement.

53

New York City Mitigation Order — On June 21, 2012, the FERC issued the first of two anticipated orders on the New York Independent System Operator's, or NYISO's, implementation of mitigation rules designed to prevent the exercise of buyer-side market power in the In-City capacity market. The order related primarily to the appropriate modeling assumptions that the NYISO should use in determining whether new entrants are subject to mitigation and, if so, what offer floor should apply to their capacity market bids. The FERC directed the NYISO to conduct its mitigation determinations using modeling parameters comparable to those used in the demand-curve reset process. The FERC also agreed with NRG and other generators that the NYISO needs to make its mitigation determination process more transparent and ordered appropriate changes. Finally, the FERC directed the NYISO IMM to provide a report on the effectiveness of the capacity market buyer-side market power mitigation program. The order did not rule on whether the NYISO had properly applied its mitigation rules to any specific market participant, instead deferring specific mitigation determinations to a future order in Docket No. EL11-50, which remains pending at the FERC.

Hudson Transfer Partners Capacity Market Mitigation Complaint — On August 3, 2012, Hudson Transfer Partners, or HTP, filed a complaint at FERC regarding the ability of its transmission cable from New Jersey to New York City to participate in the NYISO capacity markets.  HTP raises two primary allegations.  First, HTP alleges that the NYISO inappropriately determined that its capacity sales in the NYISO monthly spot capacity auction should be subject to a bid floor.  Second, HTP asserts that even if its mitigated bid does not clear the monthly spot auction, it should still receive separate reliability compensation because the emergency transfer capacity of its cable decreases the Statewide Installed Reserve Margin, providing the NYISO an alleged reliability benefit for which HTP believes it deserves compensation.  HTP's unmitigated entry into the NYISO market could have a material negative impact on NRG's existing fleet in New York City by decreasing capacity prices or by decreasing the locational capacity requirement in New York City. 

CFTC — Dodd-Frank Act Developments

On July 11, 2012, the CFTC voted to adopt final rules for the definition of a “swap” and for the end-user exemption under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act. The Company is reviewing these and other final and proposed rules that the CFTC, SEC and other federal regulators have issued or will issue under the Dodd-Frank Act, including, without limitation, position limit rules, margin rules and the definitions of “swap dealer” and “major swap participant.” The Company is also evaluating whether and how any of the rules may apply to its business. The Company does not expect that its commercial activity will result in its exceeding any position limits or its being designated as either a swap dealer or major swap participant. Major swap participants and swap dealers must comply with, among other things, margin, capital, reporting, business conduct and compliance requirements.

Management’s discussion of the results of operations for the three months ended June 30, 2012, and 2011

Income/(Loss) before income tax expense — The pre-tax income of $246 million for the three months ended June 30, 2012, compared to a pre-tax loss of $9 million for the three months ended June 30, 2011, primarily reflects:
 	 	
•	in the current year, a $52 million increase in Retail gross margin, a $36 million increase in Conventional Generation gross margin and a $25 million increase in Alternative Energy gross margin; and	

•	in the prior year, a $115 million loss on debt extinguishment of the 2016 Senior Notes.	
  
Net income — The decrease in net income of $362 million primarily reflects the drivers discussed above offset by an income tax benefit for the three months ended June 30, 2012, of $13 million, which reflects the impact of the ITC for Agua Caliente, compared with an income tax benefit of $630 million in the comparable period, which reflects the resolution of the federal tax audit in June 2011 and the related recognition of previously uncertain tax benefits.

Conventional Generation gross margin — increased by $36 million, including intercompany sales, during the three months ended June 30, 2012, compared to the same period in 2011, due to:

Increase in Texas region	$	25	
 	
Decrease in Northeast region	(16	)	
Decrease in South Central region	(3	)	
Increase in West region	10	
 	
Other (a)	20	
 	
 	$	36	

(a)	Other gross margin primarily represents revenues from the maintenance services business, which are eliminated in consolidation.	

The increase in gross margin in the Texas region was driven by:

Higher gross margin from a 9% increase in nuclear generation which related primarily to fewer outage hours in 2012 and includes business interruption proceeds received	$	23	
 	
Higher revenue due to additional bi-lateral contracts with load serving entities	13	
 	
Lower gross margin from a decrease in average realized energy prices	(6	)	
Lower gross margin from a decrease in coal generation driven by higher outages in 2012	(5	)	
 	$	25	

The decrease in gross margin in the Northeast region was driven by:

Lower gross margin from coal plants due to a 22% decrease in average realized energy prices	$	(10	)	
Lower gross margin from coal plants due to a 47% decrease in generation, resulting from the region's power generation switching from coal to gas plants	(4	)	
Higher gross margin from favorable pricing on certain load-serving contracts, as well as additional load contracts with our Retail businesses	9	
 	
Decrease in unrealized trading activities and other	(11	)	
 	$	(16	)	

The decrease in gross margin in the South Central region was driven by:

Higher gross margin from higher utilization of gas generation due to lower gas prices and higher overall sales volumes	$	52	
 	
Lower gross margin from a decrease in coal generation, as a result of lower gas prices	(18	)	
Lower gross margin from a decrease in average realized prices	(31	)	
Other	(6	)	
 	$	(3	)	

The increase in gross margin in the West region was driven by:

Higher gross margin from increased run time at Encina driven by competitor's plant outages in the region	$	6	
 	
Higher capacity margin due to the recognition of contingent rent for Long Beach	5

•	Retail gross margin — Retail gross margin increased $52 million for the three months ended June 30, 2012, compared to the same period in 2011, driven by:	

 	 	 	 	
Acquisition of Energy Plus in September 2011	$	35	
 	
Increase in usage and customer count	15	
 	
Increase from lower supply costs driven by lower natural gas prices, offset partially by lower revenues due to lower pricing on acquisitions and renewals consistent with competitive offers and lower rates on index-based customer	8	
 	
Unfavorable impact of lower volume from warmer weather in Texas in 2011	(6	)	
 	$	52	

 	 	
•	Trends — Customer counts increased by approximately 30,000 since March 31, 2012, which was primarily due to expansion into new territories and marketing efforts. While cooling and heating degree days in both periods resulted in higher than normal customer usage, weather in 2011 was warmer than in 2012. The weather resulted in higher customer usage of 8% and 11% in 2012 and 2011, respectively, when compared to ten-year normal weather. In addition, there were increases in Texas in Transmission and Distribution Service Provider rates that will remain in effect for several years. These costs are passed through to Retail customers.	

Alternative Energy gross margin

NRG's Alternative Energy business segment, which is comprised mainly of the solar and wind businesses, had gross margin of $39 million for the three months ended June 30, 2012, compared to gross margin of $14 million for the same period in 2011. The increase in gross margin primarily resulted in the addition of the Roadrunner facility, which began commercial operations in late 2011, the addition of the first six blocks of Agua Caliente, which reached commercial operations in the first six months of 2012, and an increase in gross margin from Distributed Solar.

Mark-to-market for Economic Hedging Activities
Mark-to-market for economic hedging activities includes asset-backed hedges that have not been designated as cash flow hedges and ineffectiveness on cash flow hedges. Total net mark-to-market results increased by $97 million during the three months ended June 30, 2012, compared to the same period in 2011.
The breakdown of gains and losses included in operating revenues and operating costs and expenses by region was as follows:

Mark-to-market results consist of unrealized gains and losses. The settlement of these transactions is reflected in the same caption as the items being hedged.

For the three months ended June 30, 2012, the net gains on open positions were due to increases in forward natural gas and power prices and increases in ERCOT heat rates.

For the three months ended June 30, 2011, the net losses on open positions were due to a decrease in forward power and gas prices. The reversal of loss positions acquired as part of the Reliant Energy and Green Mountain Energy acquisitions were valued using forward prices on the acquisition dates. The roll-off amounts were offset by realized losses at the settled prices and higher costs of physical power which are reflected in operating costs and expenses during the same period.

In accordance with ASC 815, the following table represents the results of the Company's financial and physical trading of energy commodities for the three months ended June 30, 2012, and 2011. The realized and unrealized financial and physical trading results are included in operating revenue. The Company's trading activities are subject to limits within the Company's Risk Management Policy.

Contract Amortization Revenue

Contract amortization represents the roll-off of in-market customer contracts valued under purchase accounting and the favorable change of $16 million as compared to the prior period in 2011 related primarily to lower contract amortization for Reliant Energy and Green Mountain Energy of $11 million and $5 million, respectively.

Other operating costs increased by $33 million for the three months ended June 30, 2012, compared to the same period in 2011, due to:

Increase in Texas region operations and maintenance expense	$	12	
 	
Increase in Retail operations and maintenance expense	6	
 	
Increase in South Central region operations and maintenance expense	7	
 	
Increase in property tax expense	13	
 	
Other	(5	)	
 	$	33	

 	 	
◦	Texas operations and maintenance— increased primarily due to maintenance spending and outage work in 2012 at S.R. Bertron to return two units to service.	
 	 	
◦	Retail operations and maintenance expense — increased primarily due to the acquisition of Energy Plus in September 2011 as well as increased customer billing costs from an increase in customer counts.	
 	 	
◦	South Central operations and maintenance expense— increased due to the 2012 spring outage at Big Cajun 2 which did not occur in 2011.	
 	 	
◦	Property tax expense— increased primarily for the Northeast region due to a reduction in property tax benefit from the New York State Empire Zone program. The reduction reflects the criteria in determining the amount of the tax credit and the annual reduction of 20% beginning in 2012 until the expiration of the program in 2016.	

Depreciation and Amortization Expense

Depreciation and amortization expense increased by $12 million for the three months ended June 30, 2012, compared to the same period in 2011. This was primarily due to additional depreciation related to solar facilities which commenced commercial operations in late 2011 and early 2012, as well as the amortization of the intangibles acquired in connection with the acquisition of Energy Plus.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased by $40 million for the three months ended June 30, 2012, compared to the same period in 2011, which was due primarily to the following:

◦Selling, general and administrative costs of $18 million for Energy Plus which was acquired in September 2011;
 	 	
◦	Increase in marketing costs of $12 million associated with customer growth efforts and new market expansion by corporate and the Retail businesses; and	

◦Increase in labor costs of $3 million for additional solar projects and acquired Distributed Solar businesses.

Equity in Earnings of Unconsolidated Affiliates

NRG's equity earnings from unconsolidated affiliates were $14 million for the three months ended June 30, 2012, compared to $12 million for the same period in 2011 primarily due to an increase in the earnings from GenConn, as the Middletown facility commenced commercial operations in June 2011.

Impairment Charge on Investment
 
As discussed in more detail in Note 4, Nuclear Innovation North America LLC Developments, Including Impairment Charge , of the Company's 2011 Form 10-K, the devastating March 2011 earthquake and tsunami in Japan, which in turn triggered a nuclear incident at the Fukushima Daiichi Nuclear Power Station, caused NRG to evaluate its investment in NINA for impairment. Consequently, NRG deconsolidated its investment in NINA and took an impairment charge in the first quarter of 2011 equal to the balance of its investment in NINA, or $481 million. To support NINA's ongoing work, NRG contributed an additional $11 million into NINA during the three months ended June 30, 2011, which NRG also expensed as an impairment charge.

Loss on Debt Extinguishment

A loss on debt extinguishment of the 2016 Senior Notes of $115 million was recorded in the three months ended June 30, 2011, which primarily consisted of the premiums paid on redemption and the write-off of previously deferred financing costs.

Interest Expense

NRG's interest expense was flat compared to the same period in 2011 due to the following:

Increase/(decrease) in interest expense	(In millions)	
Decrease for 2016 Senior Notes redeemed in May and June 2011	$	(30	)	
Decrease for capitalized interest	(28	)	
Increase for 2019 and 2021 Senior Notes issued in May 2011	22	
 	
Increase for project financings	14	
 	
Increase in derivative interest expense primarily for the Alpine interest rate swaps	14	
 	
Increase in amortization of deferred financing costs and other interest expense	8

Income Tax Benefit

For the three months ended June 30, 2012, NRG recorded an income tax benefit of $13 million on pre-tax income of $246 million. For the same period in 2011, NRG recorded an income tax benefit of $630 million on a pre-tax loss of $9 million. The effective tax rate was (5.3)% and 7000.0% for the three months ended June 30, 2012, and 2011, respectively.

For the three months ended June 30, 2012, NRG's overall effective tax rate was different than the statutory rate of 35% primarily due to the generation of ITCs from the Company's Agua Caliente solar project in Arizona, the settlement of the Green Mountain IRS audit as well as the reduction in the valuation allowance.

For the three months ended June 30, 2011, NRG's overall effective tax rate was different than the statutory rate of 35% primarily due to a benefit of $612 million resulting from the resolution of the federal tax audit. The benefit is predominantly due to the recognition of previously uncertain tax benefits that were effectively settled upon audit in June 2011 and that were mainly composed of net operating losses of $536 million which has been classified as capital loss carryforwards for financial statement purposes. In addition, a valuation allowance net decrease of $40 million increased the effective tax rate.

Management’s discussion of the results of operations for the six months ended June 30, 2012, and 2011

Loss before income tax expense —The pre-tax loss of $80 million for the six months ended June 30, 2012, compared to a pre-tax loss of $374 million for the six months ended June 30, 2011, primarily reflects:
 	 	
•	in the current year, a decrease in operating income of $356 million as compared to the prior year period, which reflects:	

◦	a decrease in net mark-to-market results for economic hedging activities of $201 million; and	

◦	a $37 million decrease in Conventional Generation gross margin driven primarily by planned and unplanned outages, lower gas prices and lower economic dispatch; and	

◦	increased operating costs of $206 million including operations and maintenance expense, depreciation and amortization and selling, general and administrative costs.	

•	offset in the prior year by:	

◦a $492 million loss on the impairment of NRG's investment in NINA, and

◦a $143 million loss on the extinguishment of the 2014 Senior Notes and the 2016 Senior Notes.
   
Net income — The decrease in net income of $308 million primarily reflects the drivers discussed above offset by an income tax benefit for the six months ended June 30, 2012, of $133 million, which reflects the impact of the ITC for Agua Caliente, compared with an income tax benefit of $735 million in the comparable period, which reflects the resolution of the federal tax audit in June 2011 and the related recognition of previously uncertain tax benefits.

Conventional Generation gross margin — decreased by $37 million, including intercompany sales, during the six months ended June 30, 2012, compared to the same period in 2011, due to:

Decrease in Texas region	$	(48	)	
Decrease in Northeast region	(27	)	
Decrease in South Central region	(4	)	
Increase in West region	9	
 	
Other (a)	33	
 	
 	$	(37	)	
 	 	
(a)	Other gross margin primarily represents revenues from the maintenance services business, which are eliminated in consolidation.	

The decrease in gross margin in the Texas region was driven by:

Lower gross margin from a decrease in coal generation driven by higher outage hours in 2012	$	(34	)	
Higher revenue due to additional bi-lateral contracts with load serving entities	27	
 	
Lower gross margin driven by lower average realized energy prices	(26	)	
Decrease in unrealized trading activities and other	(15	)	
 	$	(48	)	

The decrease in gross margin in the Northeast region was driven by:

Lower gross margin from coal plants due to a 19% decrease in realized energy prices	$	(16	)	
Lower gross margin from coal plants due to a 56% decrease in generation, resulting from the region's power generation switching from coal to gas plants	(15	)	
Lower capacity revenue due to 11% lower realized prices, due mainly to lower cleared auction prices in PJM, and slightly lower volumes.	(19	)	
Higher gross margin from favorable pricing on certain load-serving contracts, as well as additional load contracts with our Retail businesses	28	
 	
Other	(5	)	
 	$	(27	)	

The decrease in gross margin in the South Central region was driven by:

Higher gross margin from higher utilization of gas generation due to lower gas prices and higher overall sales volumes	$	91	
 	
Lower gross margin from a decrease in coal generation as a result of lower gas prices	(37	)	
Lower gross margin from a decrease in average realized merchant prices	(41	)	
Change in unrealized trading activities and other	(17	)	
 	$	(4	)	

The increase in gross margin in the West region was driven by:

Higher gross margin from increased run time at Encina driven by competitor's plant outages in the region	$	12	
 	
Higher capacity margin due to the recognition of contingent rent for Long Beach	5	
 	
Decrease in unrealized trading activities and other	(8	)

•	Retail gross margin — Retail gross margin increased $47 million for the six months ended June 30, 2012, compared to the same period in 2011, driven by:	

 	 	 	 	
Acquisition of Energy Plus in September 2011	$	64	
 	
Unfavorable impact of lower volume from mild winter weather in Texas in 2012, as well as increased risk management activities in the first quarter of 2012	(29	)	
Increase in usage and customer count	20	
 	
Decrease from lower revenues due to lower pricing on acquisitions and renewals consistent with competitive offers and lower rates on index-based customers, partially offset by lower supply costs due to lower natural gas prices	(8	)	
 	$	47	

•	Trends — Customer counts increased by approximately 61,000 since December 31, 2011, which was primarily due to expansion into new territories and marketing efforts. While cooling and heating degree days in both periods resulted in higher than normal customer usage, weather in 2012 was milder than in 2011. The weather resulted in higher customer usage of 5% and 12% in 2012 and 2011, respectively, when compared to ten-year normal weather. In addition, there were increases in Texas in Transmission and Distribution Service Provider rates that will remain in effect for several years. These costs are passed through to Retail customers.

Alternative Energy gross margin

NRG's Alternative Energy business segment, which is comprised mainly of the solar and wind businesses, had gross margin of $59 million for the six months ended June 30, 2012, compared to gross margin of $23 million for the same period in 2011. The increase in gross margin primarily resulted in the addition of the Roadrunner facility, which began commercial operations in late 2011, the addition of the first six blocks of Agua Caliente, which reached commercial operations in the first six months of 2012, and an increase in gross margin from Distributed Solar.

Mark-to-market for Economic Hedging Activities
Mark-to-market for economic hedging activities includes asset-backed hedges that have not been designated as cash flow hedges and ineffectiveness on cash flow hedges. Total net mark-to-market results decreased by $201 million during the six months ended June 30, 2012, compared to the same period in 2011.
The breakdown of gains and losses included in operating revenues and operating costs and expenses by region was as follows:

Mark-to-market results consist of unrealized gains and losses. The settlement of these transactions is reflected in the same caption as the items being hedged.

For the six months ended June 30, 2012, the net gains on open positions were due to an increase in ERCOT heat rates offset by decreases in forward natural gas, power and coal prices.

For the six months ended June 30, 2011, the net gains on open positions were due to a decrease in forward power and gas prices. The reversal of loss positions acquired as part of the Reliant Energy and Green Mountain Energy acquisitions were valued using forward prices on the acquisition dates. The roll-off amounts were offset by realized losses at the settled prices and higher costs of physical power which are reflected in operating costs and expenses during the same period.

In accordance with ASC 815, the following table represents the results of the Company's financial and physical trading of energy commodities for the six months ended June 30, 2012, and 2011. The realized and unrealized financial and physical trading results are included in operating revenue. The Company's trading activities are subject to limits within the Company's Risk Management Policy.

Contract Amortization Revenue

Contract amortization represents the roll-off of in-market customer contracts valued under purchase accounting and the favorable change of $32 million, as compared to the prior period in 2011, related primarily to lower contract amortization of $23 million and $10 million for Reliant Energy and Green Mountain Energy, respectively.

◦	Texas operations and maintenance— increased primarily due to maintenance spending and outage work in 2012 at S.R. Bertron to return two units to service, as well as timing of planned and unplanned outages in the region.	
 	 	
◦	Retail operations and maintenance expense — increased $8 million due to the acquisition of Energy Plus in September 2011 and increased due to additional customer billing costs from an increase in customer counts.	
 	 	
◦	South Central region operations and maintenance expense— increased due to the 2012 spring outage at Big Cajun 2 which did not occur in 2011.	
 	 	
◦	Northeast operations and maintenance expense— decreased in part because the prior year reflects incremental costs associated with headcount reductions.	
 	 	
◦	West operations and maintenance expense— decreased due to additional work in 2011 at Long Beach due to a compressor outage.	
 	 	
◦	Property tax expense— increased primarily for $11 million in the Northeast region due to a reduction in property tax benefit from the New York State Empire Zone program. The reduction reflects the criteria in determining the amount of the tax credit and the annual reduction of 20% beginning in 2012 until the expiration of the program in 2016.	

Depreciation and Amortization Expense

Depreciation and amortization expense increased by $37 million for the six months ended June 30, 2012, compared to the same period in 2011. This was primarily due to additional depreciation related to solar facilities which commenced commercial operations in late 2011 and early 2012, as well as the amortization of the intangibles acquired in connection with the acquisition of Energy Plus.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased by $118 million for the six months ended June 30, 2012, compared to the same period in 2011, which was due primarily to the following:

◦Selling, general and administrative costs of $38 million for Energy Plus which was acquired in September 2011;
◦Expected cash payment related to the CDWR settlement of $20 million expensed during the period;
◦Transaction costs of $9 million associated with the sale of 49% of Agua Caliente;
 	 	
◦	Increase in marketing costs of $23 million associated with customer growth efforts and new market expansion by corporate and the Retail businesses; and	
◦Increase in labor costs of $6 million for additional solar projects and acquired Distributed Solar businesses.

Equity in Earnings of Unconsolidated Affiliates

NRG's equity earnings from unconsolidated affiliates were $22 million for the six months ended June 30, 2012, compared to $10 million for the same period in 2011 primarily due to an increase in the earnings from Sherbino driven by favorable valuation of hedged positions and an increase in earnings from GenConn as the Middletown facility reached commercial operations in June 2011.

Impairment Charge on Investment
 
As discussed in more detail in Note 4, Nuclear Innovation North America LLC Developments, Including Impairment Charge , of the Company's 2011 Form 10-K, the March 2011 earthquake and tsunami in Japan, which in turn triggered a nuclear incident at the Fukushima Daiichi Nuclear Power Station, caused NRG to evaluate its investment in NINA for impairment. Consequently, NRG recorded an impairment charge of $492 million in the six months ended June 30, 2011.

Loss on Debt Extinguishment

A loss on debt extinguishment of the 2014 Senior Notes and the 2016 Senior Notes of $143 million was recorded in the six months ended June 30, 2011, which primarily consisted of the premiums paid on redemption and the write-off of previously deferred financing costs.

Interest Expense

NRG's interest expense decreased by $8 million for the six months ended June 30, 2012, compared to the same period in 2011 due to the following:

Increase/(decrease) in interest expense	(In millions)

Income Tax Benefit

For the six months ended June 30, 2012, NRG recorded an income tax benefit of $133 million on a pre-tax loss of $80 million. For the same period in 2011, NRG recorded an income tax benefit of $735 million on a pre-tax loss of $374 million. The effective tax rate was 166.3% and 196.5% for the six months ended June 30, 2012, and 2011, respectively.

For the six months ended June 30, 2012, NRG's overall effective tax rate was different than the statutory rate of 35% primarily due to the generation of ITCs from the Company's Agua Caliente solar project in Arizona.

For the six months ended June 30, 2011, NRG's overall effective tax rate was different than the statutory rate of 35% primarily due a benefit of $612 million resulting from the resolution of the federal tax audit. The benefit is predominantly due to the recognition of previously uncertain tax benefits that were effectively settled upon audit in June 2011 and that were mainly composed of net operating losses of $536 million which has been classified as capital loss carryforwards for financial statement purposes. In addition, a valuation allowance net decrease of $23 million increased the effective tax rate.

Liquidity and Capital Resources

Liquidity Position

As of June 30, 2012, and December 31, 2011, NRG's liquidity, excluding collateral received, was approximately $2.4 billion and $2.1 billion, respectively, comprised of the following:

(In millions)	June 30,
2012	 	December 31,
2011	
Cash and cash equivalents	$	1,149	
 	 	$	1,105

 	 	258	
 	
Restricted cash	208

Less: Funds deposited as collateral by hedge counterparties	(135	)	 	(258	)	
Total liquidity, excluding collateral received	$	2,406	
 	 	$	2,070	

For the six months ended June 30, 2012, total liquidity, excluding collateral received, increased by $336 million due to higher 2011 Revolving Credit Facility availability, offset by lower restricted cash balances. The increase in the 2011 Revolving Credit Facility availability was primarily due to a $304 million reduction in letters of credit due to the sale of a 49% interest in Agua Caliente in January 2012 to MidAmerican, and the addition of the NRG Repowering credit facility in January 2012 as discussed in Note 8,  Debt and Capital Leases , to this Form 10-Q. Changes in cash and cash equivalent balances are further discussed hereinafter under the heading  Cash Flow Discussion . Cash and cash equivalents and funds deposited by counterparties at June 30, 2012 were predominantly held in money market funds invested in treasury securities, treasury repurchase agreements or government agency debt.

Included in restricted cash is $75 million of cash and cash equivalents held in controlled accounts as collateral to support the Company's equity funding obligations for the Ivanpah, Agua Caliente, and CVSR projects, as required by the U.S. DOE, which guarantees the Agua Caliente, Ivanpah, and CVSR debt. This collateral can be replaced, at the Company's discretion, with a letter of credit in order to utilize such cash for other purposes. The Company's total liquidity excluding such amounts is $2.3 billion.

The line item "Funds deposited by counterparties" represents the amounts that are held by NRG as a result of collateral posting obligations from the Company's counterparties due to positions in the Company's hedging program. These amounts are segregated into separate accounts that are not contractually restricted but, based on the Company's intention, are not available for the payment of NRG's general corporate obligations. Depending on market fluctuation and the settlement of the underlying contracts, the Company will refund this collateral to the counterparties pursuant to the terms and conditions of the underlying trades. Since collateral requirements fluctuate daily and the Company cannot predict if any collateral will be held for more than 12 months, the funds deposited by counterparties are classified as a current asset on the Company's balance sheet, with an offsetting liability for this cash collateral received within current liabilities.

Management believes that the Company's liquidity position and cash flows from operations will be adequate to finance operating and maintenance capital expenditures, to fund dividends to NRG's preferred stockholders, and other liquidity commitments.

72

SOURCES OF LIQUIDITY

The principal sources of liquidity for NRG's future operating and capital expenditures are expected to be derived from new and existing financing arrangements, existing cash on hand and cash flows from operations. As described in Note 8,  Debt and Capital Leases , to this Form 10-Q and Note 12,  Debt and Capital Leases , to the Company's 2011 Form 10-K, the Company's financing arrangements consist mainly of the 2011 Senior Credit Facility, the Senior Notes, and project-related financings.

In addition, NRG has granted first liens to certain counterparties on substantially all of the Company's assets. NRG uses the first lien structure to reduce the amount of cash collateral and letters of credit that it would otherwise be required to post from time to time to support its obligations under out-of-the-money hedge agreements for forward sales of power or MWh equivalents. To the extent that the underlying hedge positions for a counterparty are in-the-money to NRG, the counterparty would have no claim under the lien program. The lien program limits the volume that can be hedged, not the value of underlying out-of-the-money positions. The first lien program does not require NRG to post collateral above any threshold amount of exposure. Within the first lien structure, the Company can hedge up to 80% of its baseload capacity and 10% of its non-baseload assets with these counterparties for the first 60 months and then declining thereafter. Net exposure to a counterparty on all trades must be positively correlated to the price of the relevant commodity for the first lien to be available to that counterparty. The first lien structure is not subject to unwind or termination upon a ratings downgrade of a counterparty and has no stated maturity date.

The Company's lien counterparties may have a claim on its assets to the extent market prices exceed the hedged prices. As of June 30, 2012, in aggregate, the hedge portfolio under the lien was in-the-money.

The following table summarizes the amount of MWs hedged against the Company's baseload assets and as a percentage relative to the Company's baseload capacity under the first lien structure as of June 30, 2012:

(b)	2012 MW value consists of August through December positions only.	
 	 	
(c)	Net baseload capacity under the first lien structure represents 80% of the Company’s total baseload assets.	

USES OF LIQUIDITY

The Company's requirements for liquidity and capital resources, other than for operating its facilities, can generally be categorized by the following: (i) commercial operations activities; (ii) debt service obligations; (iii) capital expenditures, including repowering and renewable development, and environmental; and (iv) corporate financial transactions including return of capital and dividend payments to stockholders.

Commercial Operations

NRG's commercial operations activities require a significant amount of liquidity and capital resources. These liquidity requirements are primarily driven by: (i) margin and collateral posted with counterparties; (ii) margin and collateral required to participate in physical markets and commodity exchanges; (iii) timing of disbursements and receipts (i.e. buying fuel before receiving energy revenues); (iv) initial collateral for large structured transactions; and (v) collateral for project development. As of June 30, 2012, commercial operations had total cash collateral outstanding of $71 million, and $758 million outstanding in letters of credit to third parties primarily to support its commercial activities for both wholesale and retail transactions (includes a $51 million letter of credit relating to deposits at the PUCT that cover outstanding customer deposits and residential advance payments). As of June 30, 2012, total collateral held from counterparties was $135 million in cash, and $16 million of letters of credit.

Future liquidity requirements may change based on the Company's hedging activities and structures, fuel purchases, and future market conditions, including forward prices for energy and fuel and market volatility. In addition, liquidity requirements are dependent on NRG's credit ratings and general perception of its creditworthiness.

•	Maintenance and Environmental capital expenditures — For the six months ended June 30, 2012, the Company's environmental capital expenditures included $22 million related to a project to install selective catalytic reduction systems, scrubbers and fabric filters on Indian River Unit 4. The system was operational at year-end 2011 and is undergoing performance testing.	

•	Growth Investments capital expenditures — For the six months ended June 30, 2012, the Company's growth investment expenditures included $1,875 million for solar projects and $110 million for the Company's El Segundo project. In 2012, NRG will be continuing its efforts on the solar and El Segundo projects.

Environmental Capital Expenditures

Based on current rules, technology and plans, as well as preliminary plans based on proposed rules, NRG has estimated that environmental capital expenditures from 2012 through 2016 to meet NRG's environmental commitments will be approximately $553 million. These costs are primarily associated with mercury controls to satisfy MATS on the Company's Big Cajun II, W.A. Parish and Limestone facilities and a number of intake modification projects across the fleet under state or proposed federal
316(b) rules. NRG continues to explore cost effective compliance alternatives to reduce costs. While this estimate reflects anticipated schedules and controls related to the proposed 316(b) Rule, the full impact on the scope and timing of environmental retrofits from any new or revised regulations cannot be determined until these rules are final and any legal challenges are reviewed. However, NRG believes it is positioned to meet more stringent requirements through its planned capital expenditures, existing controls, and increasing generation from renewable resources.

NRG's current contracts with the Company's rural electric cooperative customers in the South Central region allow for recovery of a portion of the region's environmental capital costs incurred as the result of complying with any change in environmental law. Cost recoveries begin once the environmental equipment becomes operational and include a capital return. The actual recoveries will depend, among other things, on the timing of the completion of the capital projects and the remaining duration of the contracts.

2012 Capital Allocation Program

On February 28, 2012, the Company announced its intention to initiate an annual common stock dividend of $0.36 per share. On July 22, 2012, NRG announced a quarterly dividend on the Company's common stock of $0.09 per share, payable August 15, 2012, to shareholders of record as of August 1, 2012. The Company also paid $72 million for open market repurchases of the Company's Senior Notes, due 2021, during the second quarter of 2012 at an average price of 98.58% of face value.

As part of the 2012 program, the Company plans to invest approximately $265 million in maintenance and environmental capital expenditures in existing assets, and approximately $470 million in solar and other projects under development.

Pending Acquisition

Under the terms of the Merger Agreement entered into on July 20, 2012, in connection with the pending acquisition, should NRG request it, GenOn will commence a “change of control” tender offer for specified GenOn debt, conditioned on the completion of the merger, or the Change in Control Offers. In addition, under the terms of the Merger Agreement, NRG may, at its election following consultation with GenOn, commence a tender offer for cash or an exchange offer for securities for all or any portion of specified GenOn debt, conditioned on the completion of the merger, which together with the Change in Control Offers, are referred to as the Debt Offers. NRG may, under the terms of the Merger Agreement, elect to also undertake a consent solicitation to alter the terms of specified GenOn debt outstanding after such tender or exchange offers. NRG intends to fund the Debt Offers and the related fees, commissions and expenses with a combination of funds available at each company (including funds available under existing credit facilities) and, to the extent necessary, new financing. NRG has obtained commitment letters from two financial institutions to fund up to $1.6 billion under a new senior secured term loan facility, to the extent such funds are necessary to consummate the Debt Offers. NRG has agreed to use reasonable best efforts to obtain the financing, to the extent required, and GenOn has agreed to use reasonable best efforts to cooperate in NRG's efforts to obtain the financing. There are no financing conditions to the merger and the merger is not conditioned upon the completion of the Debt Offers or the funding of the financing.

NOLs, Deferred Tax Assets and Uncertain Tax Position Implications, under ASC 740, Income Taxes, or ASC 740

For the six months ended June 30, 2012, the Company had a total domestic pre-tax book loss of $98 million and foreign pre-tax book income of $18 million. For the six months ended June 30, 2012, the Company generated net operating losses, or NOLs, of $64 million. As of June 30, 2012, the Company has cumulative domestic NOL carryforwards of $339 million for financial statement purposes. In addition, NRG has cumulative foreign NOL carryforwards of $314 million, of which $74 million will expire starting 2012 through 2019 and of which $240 million do not have an expiration date.

In addition to these amounts, the Company has $175 million of tax effected uncertain tax benefits. As a result of the Company's tax position, and based on current forecasts, NRG anticipates income tax payments, primarily due to foreign, state and local jurisdictions, of up to $40 million in 2012.

However, as the position remains uncertain for the $175 million of tax effected uncertain tax benefits, the Company has recorded a non-current tax liability of $65 million and may accrue the remaining balance as an increase to non-current liabilities until final resolution with the related taxing authority. The $65 million non-current tax liability for uncertain tax benefits is primarily from positions taken on various state returns, including accrued interest.

The Company continues to be under examination for various state and foreign jurisdictions for multiple years.

New and On-going Company Initiatives and Development Projects

NRG has a comprehensive set of initiatives and development projects that supports its strategy focused on: (i) excellence in safety and enhanced operating performance; (ii) earning a margin by selling electricity to end-use customers; (iii) development of new renewable and conventional power generation projects and repowering of power generation assets at existing sites; (iv) empowering retail customers with distinctive products and services; (v) engaging in a proactive capital allocation plan; and (vi) pursuing selective acquisitions, joint ventures, divestitures and investments in new and existing energy-related businesses and new technologies in order to enhance the Company's asset mix.

Renewable Development and Acquisitions

As part of its core strategy, NRG intends to continue to invest in the development and acquisition of renewable energy projects, primarily solar. NRG's renewable strategy is intended to capitalize on first mover advantage in a high growth segment of NRG's business, the Company's existing presence in regions with attractive renewable resources and the prevalence, in the Company's core markets, of state-mandated renewable portfolio standards. A brief description of the Company's development efforts with respect to solar renewable technology follows.

Solar

NRG has acquired and is developing a number of solar projects utilizing photovoltaic, or PV, as well as solar thermal technologies. The following table is a brief summary of the Company's major Utility Scale Solar projects as of June 30, 2012, that are under construction.

Below is a summary of recent developments related to solar projects:

Ivanpah — In 2011, NRG acquired 50.1% of the 392 MW Ivanpah solar project, or Ivanpah, in Ivanpah, CA. The first unit of the Ivanpah project is expected to be completed and producing power in early April of 2013. The second and third units are expected be completed in the third and fourth quarters of 2013. Power generated from Ivanpah will be sold to Southern California Edison and Pacific Gas and Electric, under multiple 20 to 25 year PPAs.

Agua Caliente— In 2011, NRG acquired 100% of the 290 MW Agua Caliente solar project, or Agua Caliente, in Yuma, AZ. On January 18, 2012, the Company completed the sale of a 49% interest in NRG Solar AC Holdings LLC, the indirect owner of Agua Caliente, to MidAmerican. Operations are scheduled to commence in phases through the first quarter of 2014, with 200 MW achieving commercial operations from January through July of 2012. On April 12, 2012, the Company received permission from the U.S. DOE to accelerate the block completion schedule. The impact of this decision will permit the Company to bring 228 MW on-line during 2012 and shortens the commercial operations date of the entire project by three months to March 2014. The acceleration will result in greater earnings earlier than originally anticipated, along with acceleration of payments under the Engineering, Procurement and Construction, or EPC, agreement which will be funded with earlier draw downs under the Agua Caliente Financing Agreement, as well as equity support by the partners. Power generated from Agua Caliente is being sold to Pacific Gas and Electric under a 25 year PPA.

CVSR— NRG owns 100% of the 250 MW CVSR project in eastern San Luis Obispo County, California. During the quarter, the Company met the conditions necessary to permit loan disbursements under the CVSR Financing Agreement, as discussed in Note 8,  Debt and Capital Leases , to this Form 10-Q. Operations are expected to commence in phases beginning in the third quarter of 2012 through the fourth quarter of 2013. Power generated from CVSR will be sold to Pacific Gas and Electric under a 25 year PPA.

Alpine — Alpine, located in Lancaster, CA, is a 66 MW facility utilizing First Solar thin film solar modules. The project, which is anticipated to reach commercial operations in the fourth quarter of 2012, obtained financing during the first quarter of 2012, as discussed in Note 8,  Debt and Capital Leases , to this Form 10-Q. Power generated from Alpine will be sold to Pacific Gas and Electric under a 20 year PPA.

Distributed Solar

NRG's installation of solar power generating systems at MetLife Stadium, Gillette Stadium and Patriot Place is continuing, with construction at MetLife and Gillette Stadium anticipated being complete by the end of the third quarter of 2012. Additionally, in February 2012, NRG announced that it will install a solar power generating system at Lincoln Financial Field, which is anticipated to be completed by the end of 2012. All of the Company's Distributed Solar projects in operation or under construction are supported by long-term PPAs.

Conventional Power Development

Projects Under Construction

The Company's El Segundo Energy Center LLC, or ESEC, is continuing construction at its El Segundo Power Generating Station, a 550 MW fast start, gas turbine combined cycle generating facility in El Segundo, California. The facility is being constructed pursuant to a 10 year, 550 MW PPA with Southern California Edison Company, or SCE.  The Company expects a commercial operation date of August 1, 2013.
 
Retail Growth Initiatives

The Company's Retail businesses are expanding in the Northeast through a combination of new sales channels, partner marketing programs, and new product offerings. NRG grew its Northeast customer base by 25% during the first half of 2012, and the Retail businesses are currently operating in 12 states.

Also, the Company continues to grow its renewable customer base. At the end of the first half of 2012, about 300,000 of its retail electricity customers were on a 100% “green” electric product. Plus, Green Mountain Energy gained an iconic commercial customer by being selected as the official green energy provider of Super Bowl XLVI and this year's Pro Bowl, with the Company offsetting the carbon emissions from each event. Green Mountain Energy also expanded in the Northeast by launching its Pennsylvania business, and celebrated its first commercial customer in New Jersey, Lord & Taylor, in June.

78

NRG also continues to expand its Reliant eSenseTM product offerings. eSense is a suite of technology solutions that uses the advanced meter system network (smart meters) that is being rolled out to customers in ERCOT.  Through June 30, 2012, Reliant had 650,000 customers using one of these products that provide customers with energy insights, choices and convenience solutions.

Reliant also continues to expand its Home SolutionsSM business with 315,000 customers utilizing home services products including protection products such as surge protection, in home power line protection, HVAC maintenance and energy efficiency products like air filter delivery and solar panel leasing.

Electric Vehicle Infrastructure Development

NRG, through its subsidiary eVgo, continues its build out of the Houston and Dallas/Fort Worth Metroplex, or DFW, EV ecosystems, and the Company is on track to be the first company to equip an entire major market with the privately funded infrastructure needed for successful EV adoption and integration. As of June 30, 2012, eVgo had 12 public fast charging Freedom Station sites operational in Houston, and 6 in DFW. In addition, eVgo had 8 sites in Houston and 12 sites in DFW under construction or in permitting. These two ecosystems are the largest privately-funded comprehensive direct current fast-charging networks in the nation. eVgo offers consumers a subscription-based plan that locks in all charging requirements for EVs at a competitive monthly fee. Based upon the successful launch of its subscription-based business model in Texas, eVgo has entered the Washington, DC/Baltimore market.

Additionally, eVgo has entered into an agreement with the CPUC to build at least 200 public fast charging Freedom Station sites and wiring and associated work to prepare 10,000 commercial and multi-family parking spaces for electric vehicle charging in California. The agreement is part of a legal settlement, as discussed in detail in Note 14,  Commitments and Contingencies , of this Form 10-Q, and is pending FERC approval.

W.A. Parish Peaking Unit and Post-combustion Carbon Capture Project

On May 3, 2012, NRG entered into a financing arrangement in the form of a $54 million tax-exempt bond financing, with the proceeds of the bonds to be used in the construction of a peaking unit at the W.A. Parish plant, with one or more components of a commercial scale carbon capture, utilization and storage system, or CCUS, which is sponsored in part by the U.S. DOE, as discussed in Note 8,  Debt and Capital Leases , of this Form 10-Q. In preparation for construction, NRG, through its wholly owned subsidiary, Petra Nova Power I LLC, acquired a gas turbine in late June 2012 and anticipates constructing the 75 MW peaking unit (prior to its use as a cogeneration facility dedicated to the CCUS) with a commercial operations date of May 1, 2013.

Construction of the CCUS is intended to allow NRG, through its wholly owned subsidiary Petra Nova LLC, or Petra Nova, to utilize the captured CO 2  in enhanced oil recovery operations in oil fields on the Texas Gulf Coast.  During the second quarter of 2012, Petra Nova completed surveying the pipeline route to the West Ranch oil field and submitted the draft Environmental Impact Statement to the U.S. DOE for review under the National Environmental Policy Act.

Off-Balance Sheet Arrangements

Obligations under Certain Guarantee Contracts

NRG and certain of its subsidiaries enter into guarantee arrangements in the normal course of business to facilitate commercial transactions with third parties. These arrangements include financial and performance guarantees, stand-by letters of credit, debt guarantees, surety bonds and indemnifications.

Retained or Contingent Interests

NRG does not have any material retained or contingent interests in assets transferred to an unconsolidated entity.

Derivative Instrument Obligations

The Company's 3.625% Preferred Stock includes a feature which is considered an embedded derivative per ASC 815. Although it is considered an embedded derivative, it is exempt from derivative accounting as it is excluded from the scope pursuant to ASC 815. As of June 30, 2012, based on the Company's stock price, the embedded derivative was out-of-the-money and had no redemption value.

79

Obligations Arising Out of a Variable Interest in an Unconsolidated Entity

Variable interest in equity investments — As of June 30, 2012, NRG has several investments with an ownership interest percentage of 50% or less in energy and energy-related entities that are accounted for under the equity method of accounting. Several of these investments are variable interest entities for which NRG is not the primary beneficiary. See also Note 9,  Variable Interest Entities, or VIEs,  to this Form 10-Q.

NRG's pro-rata share of non-recourse debt held by unconsolidated affiliates was approximately $239 million as of June 30, 2012. This indebtedness may restrict the ability of these subsidiaries to issue dividends or distributions to NRG. See also Note 16,  Investments Accounted for by the Equity Method and Variable Interest Entities,  to the Company's 2011 Form 10-K.

Contractual Obligations and Commercial Commitments

NRG has a variety of contractual obligations and other commercial commitments that represent prospective cash requirements in addition to the Company's capital expenditure programs, as disclosed in the Company's 2011 Form 10-K. See also Note 8,  Debt and Capital Leases , and Note 14,  Commitments and Contingencies , to this Form 10-Q for a discussion of new commitments and contingencies that also include contractual obligations and commercial commitments that occurred during the six months ended June 30, 2012.

Fair Value of Derivative Instruments

NRG may enter into long-term power purchase and sales contracts, fuel purchase contracts and other energy-related financial instruments to mitigate variability in earnings due to fluctuations in spot market prices and to hedge fuel requirements at generation facilities or retail load obligations. In addition, in order to mitigate interest rate risk associated with the issuance of the Company's variable rate and fixed rate debt, NRG enters into interest rate swap agreements. The following disclosures about fair value of derivative instruments provide an update to, and should be read in conjunction with,  Fair Value of Derivative Instruments  in Item 7 —  Management's Discussion and Analysis of Financial Condition and Results of Operations,  of the Company's 2011 Form 10‑K.

The tables below disclose the activities that include both exchange and non-exchange traded contracts accounted for at fair value in accordance with ASC 820,  Fair Value Measurements and Disclosures , or ASC 820. Specifically, these tables disaggregate realized and unrealized changes in fair value; disaggregate estimated fair values at June 30, 2012, based on their level within the fair value hierarchy defined in ASC 820; and indicate the maturities of contracts at June 30, 2012.

The Company has elected to disclose derivative assets and liabilities on a trade-by-trade basis and does not offset amounts at the counterparty master agreement level. Also, collateral received or paid on the Company's derivative assets or liabilities are recorded on a separate line item on the balance sheet. Consequently, the magnitude of the changes in individual current and non-current derivative assets or liabilities is higher than the underlying credit and market risk of the Company's portfolio. As discussed in Item 3  - Quantitative and Qualitative Disclosures About Market Risk, Commodity Price Risk , to this Form 10-Q, NRG measures the sensitivity of the Company's portfolio to potential changes in market prices using Value at Risk, or VaR, a statistical model which attempts to predict risk of loss based on market price and volatility. NRG's risk management policy places a limit on one-day holding period VaR, which limits the Company's net open position. As the Company's trade-by-trade derivative accounting results in a gross-up of the Company's derivative assets and liabilities, the net derivative assets and liability position is a better indicator of NRG's hedging activity. As of June 30, 2012, NRG's net derivative asset was $278 million, a decrease to total fair value of $173 million as compared to December 31, 2011. This decrease was primarily driven by the roll-off of trades that settled during the period in addition to losses in fair value due to the decreases in coal, gas and power prices and increases in ERCOT heat rates.

Based on a sensitivity analysis using simplified assumptions, the impact of a $.50 per MMBtu increase in natural gas prices across the term of the derivative contracts would result in a decrease of approximately $69 million in the net value of derivatives as of June 30, 2012. The impact of a $0.50 per MMBtu decrease in natural gas prices across the term of derivative contracts would result in an increase of approximately $37 million in net value of derivatives as of June 30, 2012.

Critical Accounting Policies and Estimates

NRG's discussion and analysis of the financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The preparation of these financial statements and related disclosures in compliance with U.S. GAAP requires the application of appropriate technical accounting rules and guidance as well as the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. The application of these policies necessarily involves judgments regarding future events, including the likelihood of success of particular projects, legal and regulatory challenges, and the fair value of certain assets and liabilities. These judgments, in and of themselves, could materially affect the financial statements and disclosures based on varying assumptions, which may be appropriate to use. In addition, the financial and operating environment may also have a significant effect, not only on the operation of the business, but on the results reported through the application of accounting measures used in preparing the financial statements and related disclosures, even if the nature of the accounting policies has not changed.

On an ongoing basis, NRG evaluates these estimates, utilizing historic experience, consultation with experts and other methods the Company considers reasonable. In any event, actual results may differ substantially from the Company's estimates. Any effects on the Company's business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the information that gives rise to the revision becomes known.

The Company identifies its most critical accounting policies as those that are the most pervasive and important to the portrayal of the Company's financial position and results of operations, and that require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain. NRG's critical accounting policies include derivative instruments, income taxes and valuation allowance for deferred tax assets, impairment of long lived assets, goodwill and other intangible assets, and contingencies.

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

NRG is exposed to several market risks in the Company's normal business activities. Market risk is the potential loss that may result from market changes associated with the Company's merchant power generation or with an existing or forecasted financial or commodity transaction. The types of market risks the Company is exposed to are commodity price risk, interest rate risk, liquidity risk, credit risk and currency exchange risk. The following disclosures about market risk provide an update to, and should be read in conjunction with, Item 7A — Quantitative and Qualitative Disclosures About Market Risk,  of the Company's 2011 Form 10-K.

Commodity Price Risk

Commodity price risks result from exposures to changes in spot prices, forward prices, volatilities, and correlations between various commodities, such as natural gas, electricity, coal, oil, and emissions credits. NRG manages the commodity price risk of the Company's merchant generation operations and load serving obligations by entering into various derivative or non-derivative instruments to hedge the variability in future cash flows from forecasted sales and purchases of electricity and fuel. NRG measures the risk of the Company's portfolio using several analytical methods, including sensitivity tests, scenario tests, stress tests, position reports, and Value at Risk, or VaR. NRG uses a Monte Carlo simulation based VaR model to estimate the potential loss in the fair value of the Company's energy assets and liabilities, which includes generation assets, load obligations, and bilateral physical and financial transactions.

As of June 30, 2012, the VaR for NRG's commodity portfolio, including generation assets, load obligations and bilateral physical and financial transactions calculated using the VaR model was $80 million.

The following table summarizes average, maximum and minimum VaR for NRG for the three months ended June 30, 2012, and 2011:

(In millions)	2012	 	2011	
VaR as of June 30	$	80	
 	 	$	65	
 	
Three months ended June 30:	 	 	
 	
Average	$	63	
 	 	$	56	
 	
Maximum	87	
 	 	65	
 	
Minimum	52	
 	 	47	
 	
Six months ended June 30:	 	 	 	
Average	$	48	
 	 	$	53	
 	
Maximum	87	
 	 	65	
 	
Minimum	24	
 	 	44	

In order to provide additional information for comparative purposes to NRG's peers, the Company also uses VaR to estimate the potential loss of derivative financial instruments that are subject to mark-to-market accounting. These derivative instruments include transactions that were entered into for both asset management and trading purposes. The VaR for the derivative financial instruments calculated using the diversified VaR model as of June 30, 2012, for the entire term of these instruments entered into for both asset management and trading, was $30 million primarily driven by asset-backed transactions.

Interest Rate Risk

NRG is exposed to fluctuations in interest rates through the Company's issuance of fixed rate and variable rate debt. Exposures to interest rate fluctuations may be mitigated by entering into derivative instruments known as interest rate swaps, caps, collars and put or call options. These contracts reduce exposure to interest rate volatility and result in primarily fixed rate debt obligations when taking into account the combination of the variable rate debt and the interest rate derivative instrument. NRG's risk management policies allow the Company to reduce interest rate exposure from variable rate debt obligations.

NRG entered into interest rate swaps, which became effective on April 1, 2011, and are intended to hedge the risks associated with floating interest rates. For the interest rate swaps, the Company will pay its counterparty the equivalent of a fixed interest payment on a predetermined notional value, and NRG receives the monthly equivalent of a floating interest payment based on the 1-month LIBOR calculated on the same notional value. All interest rate swap payments by NRG and its counterparties are made monthly and the LIBOR is determined in advance of each interest period. The total notional amount of the swaps, which mature on February 1, 2013, is $900 million.

82

In addition to those discussed above, the Company's project subsidiaries enter into interest rate swaps, intended to hedge the risks associated with interest rates on non-recourse project level debt. See Note 12,  Debt and Capital Leases,  of the Company's 2011 Form 10-K, as well as Note 8,  Debt and Capital Leases  of this Form 10-Q, for more information on the Company's interest rate swaps.

If all of the above swaps had been discontinued on June 30, 2012, the Company would have owed the counterparties $113 million. Based on the investment grade rating of the counterparties, NRG believes its exposure to credit risk due to nonperformance by counterparties to its hedge contracts to be insignificant.

As part of the CVSR financing, the Company entered into swaptions with a notional value of $686 million in order to hedge the project interest rate risk. If the swaptions were discontinued on June 30, 2012, the counterparty would have owed the Company approximately $9 million.

NRG has both long and short-term debt instruments that subject the Company to the risk of loss associated with movements in market interest rates. As of June 30, 2012, a 1% change in interest rates would result in an $11 million change in interest expense on a rolling twelve month basis.

As of June 30, 2012, the fair value of the Company's debt was $10.8 billion and the related carrying amount was $10.6 billion. NRG estimates that a 1% decrease in market interest rates would have increased the fair value of the Company's long-term debt by $822 million.

Liquidity Risk

Liquidity risk arises from the general funding needs of NRG's activities and in the management of the Company's assets and liabilities. The Company is currently exposed to additional collateral posting if natural gas prices decline primarily due to the long natural gas equivalent position at various exchanges used to hedge NRG's retail supply load obligations.

Based on a sensitivity analysis for power and gas positions under marginable contracts, a $0.50 per MMBtu change in natural gas prices across the term of the marginable contracts would cause a change in margin collateral posted of approximately $98 million as of June 30, 2012, and a 1 MMBtu/MWh change in heat rates for heat rate positions would result in a change in margin collateral posted of approximately $47 million as of June 30, 2012. This analysis uses simplified assumptions and is calculated based on portfolio composition and margin-related contract provisions as of June 30, 2012.

Credit Risk

Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, and retail customer credit risk through its retail load activities. See Note 5, Fair Value of Financial Instruments , to this Form 10-Q for discussions regarding counterparty credit risk and retail customer credit risk, and Note 7,  Accounting for Derivative Instruments and Hedging Activities , to this Form 10-Q for discussion regarding credit risk contingent features.

Currency Exchange Risk

In connection with the sale of Schkopau, as described in Note 3, Business Acquisitions and Dispositions to this Form 10-Q, NRG entered into a foreign currency swap contract to hedge the impact of exchange rate fluctuations on the sale proceeds of €140 million. As of June 30, 2012, NRG recognized approximately $1 million of losses related to the swap, which was recorded within Other income (loss), net in the statement of operations. The Company received cash consideration, net of selling expenses, of $174 million, which included $4 million related to the swap contract that was recorded as a gain within Other income (loss), net in the third quarter.
 
NRG's foreign earnings and investments may be subject to foreign currency exchange risk, which NRG generally does not hedge. As these earnings and investments are not material to NRG's consolidated results, the Company's foreign currency exposure is limited.

83

ITEM 4 — CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure ControlsandProcedures

Under the supervision and with the participation of NRG's management, including its principal executive officer, principal financial officer and principal accounting officer, NRG conducted an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures, as such term is defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Based on this evaluation, the Company's principal executive officer, principal financial officer and principal accounting officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report on Form 10-Q.

Changes in Internal Control over Financial Reporting

There were no changes in the Company's internal controls over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred in the second quarter of 2012 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

84

PART II — OTHER INFORMATION
ITEM 1 — LEGAL PROCEEDINGS

For a discussion of material legal proceedings in which NRG was involved through June 30, 2012, see Note 14, Commitments and Contingencies , to this Form 10-Q.

ITEM 1A — RISK FACTORS
Information regarding risk factors appears in Part I, Item 1A, RiskFactors Related to NRG Energy, Inc., in the Company's 2011 Form 10-K. The information presented below updates, and should be read in conjunction with, the risk factors and information disclosed in our 2011 Form 10-K. Except as presented below, there have been no material changes in our risk factors since those reported in our 2011 Form 10-K. Further information concerning the proposed merger with GenOn Energy, Inc. will be included in a joint proxy statement/prospectus contained in the registration statement on Form S-4 to be filed by NRG with the SEC.

Risks related to the proposed merger with GenOn Energy, Inc.

We may be unable to obtain the approvals required to complete the merger with GenOn Energy, Inc. or, in order to do so, the combined company may be required to comply with material restrictions or conditions.

On July 22, 2012, we announced the execution of a merger agreement with GenOn Energy, Inc., or GenOn. Before the merger may be completed, both NRG and GenOn will need to obtain stockholder approval in connection with the proposed transaction. In addition, various filings must be made with FERC and various regulatory, antitrust and other authorities in the United States. These governmental authorities may impose conditions on the completion, or require changes to the terms, of the merger, including restrictions or conditions on the business, operations or financial performance of the combined company following completion of the merger. These conditions or changes, including potential litigation brought in connection with the proposed merger, could have the effect of delaying completion of the merger or imposing additional costs on or limiting the revenues of the combined company following the merger, which could have a material adverse effect on the financial results of the combined company and/or cause either NRG or GenOn to abandon the merger.

If we are unable to complete the merger, we still will incur and will remain liable for significant transaction costs, including legal, accounting, filing, printing and other costs relating to the merger. Also, depending upon the reasons for not completing the merger, we may be required to pay GenOn a termination fee of $120 million.

If completed, our merger with GenOn may not achieve its intended results.

We entered into the merger agreement with the expectation that the merger would result in various benefits, including, among other things, cost savings and operating efficiencies. Achieving the anticipated benefits of the merger is subject to a number of uncertainties, including whether the businesses of NRG and GenOn are integrated in an efficient and effective manner. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues generated by the combined company and diversion of management's time and energy and could have an adverse effect on the combined company's business, financial results and prospects.

We will be subject to business uncertainties and contractual restrictions while the merger with GenOn is pending that could adversely affect our financial results.

Uncertainty about the effect of the merger with GenOn on employees, customers and suppliers may have an adverse effect on our business. Although we intend to take steps designed to reduce any adverse effects, these uncertainties may impair our ability to attract, retain and motivate key personnel until the merger is completed and for a period of time thereafter, and could cause customers, suppliers and others that deal with us to seek to change existing business relationships.

Employee retention and recruitment may be particularly challenging prior to the completion of the merger, as employees and prospective employees may experience uncertainty about their future roles with the combined company. If, despite our retention and recruiting efforts, key employees depart or fail to accept employment with us because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the combined company, our financial results could be affected.

85

The pursuit of the merger and the preparation for the integration of NRG and GenOn may place a significant burden on management and internal resources. The diversion of management attention away from ongoing business concerns and any difficulties encountered in the transition and integration process could affect our business, results of operations and financial condition.

In addition, we are restricted under the merger agreement, without GenOn's consent, from making certain acquisitions and taking other specified actions until the merger occurs or the merger agreement terminates. These restrictions may prevent us from pursuing otherwise attractive business opportunities and making other changes to our business prior to completion of the merger or termination of the merger agreement.

Risks related to proposed regulation under the Dodd-Frank Act

NRG cannot fully assess at this time the impact of the ongoing efforts by the CFTC and other federal regulators to implement the Dodd-Frank Act and to write rules and regulations that will increase the regulation of over-the-counter derivatives, including those related to energy commodities. The CFTC's rules and regulations will ultimately increase the number and types of derivatives that must be centrally cleared and increase the standardization of contracts and products, collateral and credit standards, and capital requirements. Such changes could negatively impact NRG's ability to hedge its portfolio and optimize its assets in an efficient, cost-effective manner by, among other things, limiting NRG's ability to utilize liens as collateral, increasing its transaction costs and decreasing liquidity in the forward commodity markets.
