EXPLANATORY NOTE

     This Form 8-K/A is being filed to update our previously filed pro forma financial statements to include the preliminary pricing and terms for the registration of unsecured debt securities, preferred stock and common stock, and the non-registered bank credit facility, the issuance of which are together referred to as the Financing Transactions. The preliminary pricing and terms include a more detailed disclosure of the expected tranches of the proposed unsecured debt securities, the expected weighted average annual interest rate and term.

     At the Company’s election, on a pro forma basis as of September 30, 2005, consideration with a fair value of $368 million, or the Other Consideration, may be comprised of either an additional 9,038,125 shares of common stock, additional cash, shares of a new series of NRG’s Cumulative Preferred Stock or a combination of the foregoing. This Form 8-K/A updates our previously filed pro forma financial statements as we are now assuming that the Other Consideration will be paid in cash only, instead of Cumulative Preferred Stock.

     This Form 8-K/A includes additional sensitivity analysis disclosures related to the new debt instruments, the pricing of common stock and the proposed preferred dividend for the Mandatorily Convertible Preferred Stock. This Form 8-K/A further updates the following footnotes related to the Financing Transactions: footnotes 9, 10, 11 and 14 to the Pro Forma Combined Condensed Balance Sheet as of September 30, 2005, footnotes 4, 9, and 16 to the Pro Forma Combined Statement of Operations for the Nine Months Ended September 30, 2005 and footnotes 4, 8 and 16 to the Pro Forma Combined Statement of Operations for the Year Ended December 31, 2004.

Item 8.01 Other Events

     NRG Energy, Inc., or NRG, has filed a registration statement on Form S-3 to register unsecured debt securities, preferred stock and common stock, and the non-registered bank credit facility, the issuance of which are together referred to as the Financing Transactions. The Financing Transactions will be entered into to finance the Acquisition (described below) and re-capitalize the Company. In connection with this registration statement, NRG is filing the unaudited pro forma analyses as set forth below.

     On September 30, 2005, NRG entered into an Acquisition Agreement (the “Acquisition Agreement”) with Texas Genco LLC, a Delaware limited liability company (“Texas Genco”), and each of the direct and indirect owners of Texas Genco (the “Sellers”). Pursuant to the Acquisition Agreement, upon the terms and subject to the conditions set forth therein, the Company agreed to purchase all of the outstanding equity interests in Texas Genco (the “Acquisition”). We expect to close this transaction during the first quarter of 2006.

     On a pro forma basis, we estimate that the total purchase price will be $6.121 billion. This amount is comprised of common stock, cash and capitalized expenses. The number of shares to be issued to the Sellers is 35,406,320, of this amount 19,346,788 are from treasury and 16,059,532 are newly issued shares, at a price of $45.37 which is the average NRG share price immediately before and after the pro forma date of closing, or September 30, 2005, with a total value of $1.6 billion for the shares. NRG will pay $4.399 billion in cash and will capitalize expenses of $116 million. The purchase includes the assumption by the Company of approximately $2.74 billion of Texas Genco indebtedness. As a result of the Acquisition, Texas Genco will become a wholly owned subsidiary of the Company.

     Of the pro forma $6.121 billion consideration to the Sellers upon consummation of the Acquisition, the Company is paying $4.399 billion in cash, and must issue a minimum of 35,406,320 shares of the Company’s common stock. At the Company’s election, the Other Consideration with a fair value of $368 million may be comprised of either an additional 9,038,125 shares of common stock, additional cash, shares of a new series of NRG’s Cumulative Preferred Stock or a combination of the foregoing. If issued, the aggregate liquidation preference of the Cumulative Preferred Stock will be equal to the average trading value of 9,038,125 shares of the Company’s common stock over a twenty trading day period prior to closing. If the Company elects to pay all or a portion of the remaining purchase price in cash, the amount payable in cash would be calculated in the same manner. On a pro forma basis we have assumed that the Other Consideration will be paid in cash.

     NRG expects to finance the cash requirements of the Acquisition through a combination of a new senior secured credit facility, an unsecured high yield notes offering and the sale of common and preferred equity securities in the public markets. We have received a commitment letter from Morgan Stanley Senior Funding, Inc. (“Morgan Stanley”), Citigroup Global Markets, Inc. (“Citigroup”) and other institutional lenders, to provide us with up to $5.2 billion in senior secured debt financing, including up to $3.2 billion under a senior first priority term loan facility, up to $1 billion under a senior first priority secured revolving credit facility and up to $1 billion

3

under a senior first priority secured synthetic letter of credit facility. We expect to increase the amount of the senior first priority term loan portion of the senior secured debt financing from $3.2 billion to $3.575 billion, as reflected in the pro forma financial information included in this Form 8-K/A. The commitment letter further provides for up to $5.1 billion in bridge financing to fund all necessary amounts not provided for under the senior secured debt financing. NRG does not intend to draw down on the bridge financing unless the contemplated high yield debt financing and preferred and common equity financings are for some reason unavailable at the time of the closing. The commitment letter is subject to customary conditions to consummation, including the absence of any event or circumstance that would have a material adverse effect on the business, assets, properties, liabilities, condition (financial or otherwise) or results of operations, taken as a whole, of Texas Genco, or Texas Genco and NRG combined, since June 30, 2005. We have agreed to pay Morgan Stanley and Citigroup $44.6 million in connection with the commitment letter, or the Bridge Loan Commitment Fee, and have agreed to indemnify Morgan Stanley and Citigroup against certain liabilities.

     The Financing Transactions will enable us to refinance our outstanding Second Priority Notes and Credit Facility. This Credit Facility includes a senior secured term loan, a revolving credit facility and funded letter of credit facility. In addition, the new financing will supply the source of funds to acquire Texas Genco and to repay their Term Loan Facility and Senior Notes. The following is a brief summary of the companies’ outstanding debt instruments that we expect to refinance with the new debt structure:

	Old Debt Structure
	As of September 30, 2005				New Debt		New Debt
(in millions)	NRG		Texas Genco		Structure		Term
Term loan – adjustable interest		447		1,614		3,575	7 years
Second Priority Notes		1,080		n/a		n/a		n/a
Unsecured senior notes – fixed rate		n/a		1,125		n/a		n/a
Unsecured senior notes – fixed rate		n/a		n/a		2,200	10 years
Unsecured senior notes – fixed rate		n/a		n/a		1,100	8 years
Unsecured senior notes – floating rate		n/a		n/a		300	8 years
Revolving credit facility		150		325		1,000	5 years
Funded letter of credit facility		350		694		n/a		n/a
Synthetic letter of credit facility		n/a		n/a		1,000	5 years

     Based on the preliminary pricing, we have assumed the following interest rates for the new debt instruments during the year ended December 31, 2004 and the nine months ended September 30, 2005:

	New Debt		New Debt	Assumed interest			Assumed interest
(in millions)	Structure		Term	rate during 2004			rate during 2005
Term loan – adjustable interest		3,575	7 years		6.734	%		6.621	%
Unsecured senior notes – fixed and floating rate*		3,600	8-10 years		7.500	%		7.500	%

* Pending final pricing of each tranche of unsecured senior notes, we have assumed a weighted average annual interest rate of 7.5%.

     On January 17, 2006 the Company entered into a number of forward interest rate swaps to effectively fix the interest rate for part of the new term loan, as described in the table below:

Period from		Weighted Average
initiation of swap	Hedged Principal	Swap Rate
1st year	$2.15 billion		4.774	%
2nd year	$2.03 billion		4.773	%
3rd year	$1.89 billion		4.777	%
4th year	$1.74 billion		4.783	%
5th year	$1.55 billion		4.786	%

     NRG will pay an annual fee of 0.5% for the new revolving credit facility, and when drawn upon, the adjustable interest rate would be the London Interbank Offering Rate plus 2%. On a pro forma basis, we have assumed an annual fee of 2% to have access to the synthetic letter of credit facility.

     On May 19, 2005, pursuant to the exercise of a right of first refusal by Texas Genco, subsequent to a third party offer to American Electric Power, or AEP, in early 2004, Texas Genco acquired from AEP an additional 13.2% undivided interest in South Texas Project, or STP. We refer to that acquisition as the “ROFR.” As a result, Texas Genco now owns a 44.0% undivided interest in STP. For pro forma purposes, NRG has accounted for the ROFR as a business acquisition and included the ROFR in our pro forma adjustments to the statements of operation.

     On December 8, 2005 NRG entered into an Asset Purchase and Sale Agreement to sell all the assets of NRG Audrain Generating LLC, or Audrain, to AmerenUE, a subsidiary of Ameren Corporation. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation. The purchase price is $115 million, subject to customary purchase price adjustments. The transaction is expected to close during the first half of 2006. The sale is subject to customary approvals, including Federal Energy Regulatory Commission, Missouri Public Utilities Commission, Illinois Commerce Commission, and Hart-Scott-Rodino review. We expect to record a gain of approximately $15 million at closing.

     On December 27, 2005, NRG entered into purchase and sale agreements for projects co-owned with Dynegy, Inc., or Dynegy, Under the agreements, NRG will acquire Dynegy’s 50% ownership interest in WCP (Generation) Holdings, Inc., or WCP, and become the sole owner of WCP’s 1,808 MW of generation in Southern California.In addition, NRG is selling to Dynegy its 50% ownership interest in Rocky Road Power LLC, or Rocky Road, a 330 MW gas-fueled, simple cycle peaking plant located in Dundee, Illinois. Both of these transactions are conditioned upon one another and NRG will pay Dynegy a net purchase price of $160 million at closing. NRG will fund the net purchase price with cash held by WCP. NRG anticipates closing both transactions during the first quarter 2006.

     WCP owns and operates 1,808 MW in Southern California as listed below.

Plant	MW		Primary Fuel	Status
El Segundo Power, LLC (El Segundo)		670	Gas	Tolling agreement through 12/31/05 and from May 1, 2006 through April 30, 2008
Cabrillo Power I LLC (Encina)		965	Gas	Reliability-Must-Run, or RMR, status for Units 1-3 and 5 through 12/31/2006.
Cabrillo Power II LLC (13 combustion    turbines in San Diego area)		173	Gas	RMR status through 12/31/2006
Long Beach Generation LLC (Long Beach)		N/A	N/A	Retired
Total		1,808

     We have determined that the fair value of our equity investment in Rocky Road is equal to the negotiated price of $45 million. The current carrying value of our investment in Rocky Road is $70.2 million and we therefore expect to record in the fourth quarter of 2005 an other than temporary impairment in our investment. On a pro forma basis the total impairment is in the amount of $25.2 million. As the tax basis of Rocky Road is higher than the consideration received and it is not probable that we can utilize any future benefit from this capital loss, there is no tax expense/(benefit) related to this transaction.

     The historical consolidated financial information and the unaudited pro forma combined financial information set forth below should be read in conjunction with (a) the consolidated financial statements of NRG Energy, Inc., the related notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operation included in NRG Energy, Inc.’s annual report on Form 10-K for the year ended December 31, 2004 as amended by the Current Report on Form 8-K filed on December 20, 2005, and quarterly report on Form 10-Q for the nine months ended September 30, 2005; (b) the consolidated financial statements of Texas Genco LLC and Texas Genco Holdings, Inc., the related notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operation for the year ended December 31, 2004 and for the nine months ended September 30, 2005 filed and incorporated herein by reference as Exhibits 99.01, 99.02 and 99.03 to this current report on Form 8-K/A, as filed with the current report on Form 8-K filed on December 21, 2005 and incorporated herein by reference; and (c) with the financial statements of West Coast Power LLC and the related notes thereto included in NRG Energy, Inc.’s annual report on Form 10-K as Exhibit 99.1 for the year ended December 31, 2004 and financial statements as of and for the nine months ended September 30, 2005 as found in Exhibit 99.06 to this current report on Form 8-K/A, as filed with the current report on Form 8-K/A filed on January 5, 2006 and incorporated herein by reference.

     The Acquisition will be accounted for using the purchase method of accounting and, accordingly, the purchase price will be allocated to the assets acquired and liabilities assumed based on the estimated fair value of such assets and liabilities at the date of acquisition. As it is difficult to estimate a pro forma allocation of purchase price without completed asset appraisals, we have made a preliminary allocation estimate based on the latest available information. For purposes of these pro forma statements we have assumed that the consideration paid in excess of the historical book value of net assets acquired is related to the step-up in fair value of Texas Genco’s emission credit inventory, a step-up in the value of Texas Genco’s fixed assets, and an increase in liabilities for assumed out-of-market contracts. Once the Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices, and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

     The following summarizes the estimated pro forma purchase price and allocation impact of the Acquisition on NRG’s financial statements at September 30, 2005:

	(in millions)
Cash paid to Sellers			$	4,399
NRG common stock issued to Sellers(1)				1,606
Fees and transaction costs
Fees for early repayment of existing Texas Genco debt		99
Investment banker fees		17
Total capitalized acquisition expenses				116
Total pro forma Purchase Price				6,121
Purchase price allocation:
Net book value of Texas Genco assets and liabilities acquired				773
Write-off of Texas Genco deferred financing fees				(109	)
Step-up in fixed assets				4,943
Step-up in emission credit inventory				1,309
Increase in out-of-market contracts(2)				(2,506	)
Elimination of Texas Genco goodwill				(791	)
Increase in current deferred tax assets				391
Increase in non-current deferred tax liabilities				(260	)
NRG goodwill				2,371
Total allocated			$	6,121

(1)

The Company will issue a minimum of 35,406,320 shares of its common stock. At the Company’s election, the remaining consideration may be comprised of either an additional 9,038,125 shares of common stock, additional cash, shares of a new series of NRG’s Cumulative Preferred Stock or a combination. The value of this remaining consideration will be equal to the average trading value of 9,038,125 shares of the Company’s common stock over a twenty day trading period prior to closing. On a pro forma basis we have assumed this amount has been paid in cash totaling $368 million.

(2)

Assuming the acquisition had occurred at September 30, 2005, a number of energy and gas sale contracts initiated by Texas Genco were considered to be out-of-the-money and consequently, NRG would have to recognize a liability for these contracts at Acquisition. The fair value of these contracts was assessed based on forecasted energy prices that were calculated as of the pro forma acquisition date. A number of these contracts have already been recorded as a liability by Texas Genco. At Acquisition, we will increase this liability by an additional $2.5 billion to a total fair value of $3.4 billion. The lives of these contracts extend until the end of 2010, however, approximately 91% of the value of these contracts extend until the end of 2008 only. The approximate amortization of these liabilities for the fiscal year of 2006 is $1.3 billion, for the fiscal year of 2007 is $1.1 billion and for the fiscal year of 2008 is $0.7 billion.

     The WCP Acquisition is a step acquisition as our original equity investment was initiated in a prior period. The purchase price of each acquisition is determined separately per the consideration given at the date of each transaction. Therefore, the purchase price allocation is determined separately based on the fair value for the percentage of net assets acquired at the date of each transaction. The WCP Acquisition will be accounted for using the purchase method of accounting and, accordingly, the purchase price will be allocated to the percentage of assets acquired and liabilities assumed based on the estimated fair value of such assets and liabilities at the date of the transaction. As it is difficult to estimate a pro forma allocation of purchase price without completed asset appraisals, we have made a preliminary allocation estimate based on the latest available information. For purposes of these pro forma statements we have assumed that the consideration paid below the historical book value of net assets acquired is related to the reduction in fair value of WCP’s fixed assets, with an offsetting increase in fair value in WCP’s land and an increase in the fair value of WCP’s emission credit inventory. Once the WCP Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices and analyses of the income tax effects of the acquisition.

     The following summarizes the estimated pro forma purchase price and allocation impact of the WCP Acquisition on NRG’s financial statements at September 30, 2005:

	(in millions)
Cash paid to Dynegy, Inc.	$	160
Fair value of NRG’s 50% investment in Rocky Road LLC		45
Total pro forma Purchase Price of WCP Acquisition		205
Purchase price allocation:
Net book value of 50% of WCP assets and liabilities acquired		318
Incremental reduction in value in 50% of WCP’s fixed assets		(120	)
Incremental increase in value in 50% of WCP’s land		24
Incremental increase in 50% of WCP’s emission credit inventory		19
Total allocation		241
Excess over cost, or Negative Goodwill	$	(36	)
Negative Goodwill is assigned proportionately to reduce the value of fixed assets		(13	)
Negative Goodwill is assigned proportionately to reduce the value of land		(16	)
Negative Goodwill is assigned proportionately to reduce the value of emission credit inventory		(7	)
Total amount allocated after assignment of Negative Goodwill	$	205

7

     Per our current valuation of WCP’s assets and liabilities, the transaction included an element of an excess over cost, or Negative Goodwill, which has been proportionately allocated to reduce the value of WCP’s acquired assets as noted in the table above. Following the proportionate allocation of Negative Goodwill, the incremental increase/(decrease) in value to the acquired assets is as follows:

Final incremental decrease in value in 50% of WCP’s fixed assets	(133	)
Final incremental increase in value in 50% of WCP’s land	8
Final incremental increase in value in 50% of WCP’s emission credit inventory	12

     We have not associated any deferred taxes to the WCP Acquisition as we believe that the value of the assets and liabilities acquired will be very similar for tax and financial reporting purposes, and any basis differences will only be generated after the closing once timing differences due to depreciation and amortization arise. On a pro forma basis, there are is no basis difference as of September 30, 2005.

Sensitivity Analysis for the preliminary pricing of our common stock, new debt instruments and Mandatorily Convertible Preferred Stock:

Common stock sensitivity analysis:

     Common stock issued to Sellers— To the extent NRG’s common stock price is different at the closing of the Acquisition the total value of the shares to be issued to the Sellers will change. The fair value of each share issued to the Sellers is $45.37. This fair value is based on the average NRG share price immediately before and after the pro forma date of closing, or September 30, 2005. A $1.00 change in the price per share of NRG’s common stock will impact the fair value of the common stock issued to the Sellers, and consequently the Acquisition purchase price, by approximately $35 million. Any change in our common stock price will also impact our pro forma shareholders equity by the same amount.

     Other Consideration— On a pro forma basis, the fair value of the Other Consideration is $368 million. This fair value is equal to the average trading value of 9,038,125 shares of the Company’s common stock over a twenty trading day period prior to closing. A $1.00 change in the average trading value of NRG’s common stock will impact the amount paid to the Sellers, and consequently the Acquisition purchase price, by approximately $9 million. We have assumed that the Other Consideration will be paid in cash and we intend to use our cash on hand to fund any portion of this cash amount in excess of $368 million.

     Common stock issued to the public— For purposes of the public offering of common stock, NRG plans to raise $1 billion and the amount of shares to be issued could vary based on the closing price. On a pro forma basis, based on a share price as of September 30, 2005 of $42.60, a total of 23,474,178 shares would be issued to the public. Based on NRG’s closing price of its traded common stock on January 18, 2006 of $49.21, only 20,321,073 shares would be issued to the public, a decrease of 3,153,105 shares. Assuming a sensitivity of an increase/(decrease) of $1 to NRG’s stock price, on a pro forma basis, Basic EPS and Diluted EPS for the year ended December 31, 2004 and for the nine months ended September 30, 2005 would change as follows:

			Year ended December 31, 2004				Nine months ended September 30, 2005
	Decrease to pro forma		Increase to pro		Increase to pro		Increase to pro		Increase to pro

Increase in non-current deferred tax liability		(259,983	)
Goodwill		2,371,026
Total	$	6,120,907

     Due to the lack of asset appraisals and a future closing date, it is very difficult to estimate a pro forma allocation of purchase price. However, for purposes of these pro forma statements, we have assumed that the consideration in excess of the net assets acquired is related to a step-up in the value of Texas Genco’s fixed assets, a step-up in the value of Texas Genco’s emission credit inventory and goodwill. Once the Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices, the purchase price and allocation to net assets acquired and liabilities assumed and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of

12

staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

III. Acquisition of WCP and Sale of Rocky Road:

(21) On December 27, 2005, NRG entered into purchase and sale agreements for projects co-owned with Dynegy. Under the agreements, NRG will acquire Dynegy’s 50% ownership interest in WCP, and become the sole owner of WCP’s 1,808 MW of generation in Southern California. In addition, NRG is selling to Dynegy its 50% ownership interest in Rocky Road, a 330 MW gas-fueled, simple cycle peaking plant located in Dundee, Illinois. Both of these transactions are conditioned upon one another and NRG will pay Dynegy a net purchase price of $160 million at closing. NRG will fund the net purchase price with cash held by the WCP partnership. NRG anticipates closing both transactions during the first quarter 2006.

(22) The total consideration for the WCP Acquisition is comprised of the following:

Cash paid to Dynegy, Inc.		160,000
Fair value of our 50% investment in Rocky Road		45,000
Total pro forma Purchase Price for the WCP Acquisition	$	205,000

The preliminary purchase price allocation is as follows:

Purchase price allocation:
Net book value of 50% of WCP assets and liabilities acquired		317,654
Incremental reduction in value in 50% of WCP’s fixed assets		(120,255	)
Incremental increase in value in 50% of WCP’s land		24,576
Incremental increase in value in 50% of WCP’s emission credit inventory		18,751
Total allocation		240,726
Excess over cost, or Negative Goodwill	$	(35,726	)
Negative Goodwill is assigned proportionately to reduce the value of fixed assets		(12,970	)
Negative Goodwill is assigned proportionately to reduce the value of land		(16,359	)
Negative Goodwill is assigned proportionately to reduce the value of emission credit inventory		(6,397	)
Total amount allocated after assignment of Negative Goodwill	$	205,000

     Per our current valuation of WCP’s assets and liabilities, the transaction included an element of an excess over cost, or Negative Goodwill, which has been proportionately allocated to reduce the value of WCP’s acquired assets as noted in the table above. Following the proportionate allocation of negative goodwill, the incremental increase/(decrease) in value to the acquired assets is as follows:

Final incremental decrease in value in 50% of WCP’s fixed assets	(133,225	)
Final incremental increase in value in 50% of WCP’s land	8,217
Final incremental increase in value in 50% of WCP’s emission credit inventory	12,354

     We have not associated any deferred taxes to the WCP Acquisition as we believe that the value of the assets and liabilities acquired will be equal for tax and financial reporting purposes.

     As it is difficult to estimate a pro forma allocation of purchase price without completed asset appraisals, we have made a preliminary allocation estimate based on the latest available information. For purposes of these pro forma statements we have assumed that the consideration paid below the historical book value of net assets acquired is related to the reduction in the fair value of WCP’s fixed assets, with an offsetting increase in fair value in WCP’s land and an increase in the fair value of WCP’s emission credit inventory. Once the WCP Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices and analyses of the income tax effects of the acquisition.

(23) The reduction in our equity investments reflects the sale of Rocky Road and consolidation of our WCP investment:

Equity investment in WCP	152,819
Total	223,066

The allocation of NRG’s equity investment’s carrying value for 50% of WCP is as follows:

Current carrying value of NRG’s 50% investment in WCP	152,819
Allocation of current carrying value:
Net book value of 50% of WCP’s assets and liabilities acquired	317,653
Incremental reduction in value in 50% of WCP’s fixed assets	(164,834	)
Total allocation	152,819

The total reduction in value of WCP’s fixed assets is as follows:

Current WCP Acquisition’s incremental decrease in value WCP’s fixed assets	(133,225	)
Current WCP Acquisition’s incremental increase in value of WCP’s land	8,217
Incremental reduction in value of WCP’s fixed assets as reflected in our 50% equity investment in WCP	(164,834	)
Total	(289,842	)

(24) We have determined that the fair value of our equity investment in Rocky Road is equal to the negotiated price of $45 million. The current carrying value of our investment in Rocky Road is $70.2 million and we therefore expect to record in the fourth quarter of 2005 an other than temporary impairment in our investment. On a pro forma basis the total impairment is in the amount of $25.2 million. As the tax basis of Rocky Road is higher than the consideration received and it is not probable that we can utilize any future benefit from this capital loss, there is no tax expense/(benefit) related to this transaction.

(25) Certain items from WCP’s balance sheet have been reclassified to match NRG’s balance sheet classifications. The amount of $10 million has been moved from “Prepayments and other current assets” to “Collateral on deposit in support of energy risk management activities”. We have also reduced inventory by $3.8 million to reflect the classification of emission credits as an intangible asset. We have also condensed the amount of $16.3 million from “Accounts payable affiliates” with “Accounts Payable”.

Footnotes to Pro Forma Combined Statement of Operations for the Nine Months Ended September 30, 2005

(1)	The Pro Forma Combined Texas Genco LLC Statement of Operations for the Nine Months Ended September 30, 2005 can be found in Exhibit 99.10.
(2)	On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with Ameren UE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation.
(3)	Reflects pro forma results of additional 13.2% interest in STP acquired in the ROFR for the period from January 1, 2005 until ROFR acquisition date on May 19, 2005.
(4)	Reflects the reversal of interest expense associated with NRG’s existing debt structure, prior to the acquisition of Texas Genco and the recording of interest expenses associated with the new debt structure:

Reversal of interest expense associated with NRG’s existing debt structure	$	108,782
Interest expense associated with the refinancing of NRG’s debt		(87,157	)
Total	$	21,625

(5)	Reflects the tax effect of both the pro forma adjustments (pro forma effective tax rate of 39.5%) and Texas Genco’s pass-through earnings (pro forma effective tax rate of 34.5% — the difference in tax rates is due to a 0% state corporate income tax rate for Texas Genco in the state of Texas), which will now generate taxable income for the combined entity.
(6)	Reflects the increase in revenue due to the amortization of the out-of-money contracts recorded for the Acquisition of Texas Genco(a).
(7)	Reflects the reversal of Management Fees of $7.5 million which will not be applicable following the Acquisition and the additional amortization expense for emission credits of $91.5 million based on the amount of credits used during this period by Texas Genco.
(8)	Reflects the increase in depreciation expense due to the step-up in the value of fixed assets at the Acquisition of Texas Genco(a).
(9)	Reflects the reversal of interest expense associated with Texas Genco’s existing debt structure and the recording of interest expenses associated with the acquisition financing:

Reversal of interest expense associated with Texas Genco existing debt structure		141,723
Interest expense associated with the acquisition financing		(284,808	)
Total	$	(143,085	)

(a) Due to the lack of asset appraisals and a future closing date, it is difficult to estimate a pro forma allocation of purchase price. However, for purposes of these pro forma statements we have assumed that the consideration in excess of the net assets acquired is related to a step-up in the value of Texas Genco’s fixed assets, a step-up in the value of Texas Genco’s emission credit inventory and Goodwill. Once the Acquisition is closed, the excess of the estimated purchase price may differ considerably from these assumptions based on the results of appraisals, finalization of the purchase price as a result of closing and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

On a pro forma basis we have made a number of assumptions per our best estimates. We have assumed an average remaining useful life of 25 years of the fixed assets acquired, rendering a significant incremental pro forma increase in depreciation expense. The amortization of the emission credit inventory is based on Texas Genco’s use of credits for the period. The amortization of the assumed liability for Texas Genco’s out-of-market contracts is mimicking the expected amortization for the nine month period which would begin on January 1, 2006. Actual results may differ considerably from these pro forma assumptions.

(10)	On December 27, 2005, NRG entered into purchase and sale agreements for projects co-owned with Dynegy. Under the agreements, NRG will acquire Dynegy’s 50 percent ownership interest in WCP, and become the sole owner of WCP’s 1,808 MW of generation in Southern California. In addition, NRG is selling to Dynegy its 50 percent ownership interest in Rocky Road, a 330 MW gas-fueled, simple cycle peaking plant located in Dundee, Illinois. Both of these transactions are conditioned upon one another and NRG will pay Dynegy a net purchase price of $160 million at closing. NRG will fund the net purchase price with cash held by the WCP partnership. NRG anticipates closing both transactions during the first quarter 2006.
(11)	Due to the step-up in value of emission credits pursuant to the WCP Acquisition, this amount reflects the additional amortization expense of emission credits of $1.3 million. This additional expense was derived from the actual amount of credits used during this period by WCP.
(12)	Reflects the decrease in depreciation expense due to the reduction in the value of fixed assets at the acquisition of WCP. This reduction in the value of fixed assets is due to the WCP Acquisition as well as the reduction in the value of fixed assets as reflected in NRG’s carrying value of it’s equity investment in WCP. Also see footnote 24 to the pro forma balance sheet as of September 30, 2005 for further discussion. We have assumed an average remaining useful life of 6 years of the fixed assets acquired, rendering a pro forma decrease in depreciation expense. The remaining useful life of 6 years is based on preliminary estimates based on the latest available information. This assumption may change based on the final appraisal of WCP.
(13)	Reflects the reduction in equity earnings in unconsolidated affiliates assuming WCP was a wholly owned subsidiary as of January 1, 2004 and that we no longer owned a 50% interest in Rocky Road. The reduction in equity earnings from these investments is as follows:

Equity earnings from our 50% investment in WCP	$	15,218
Equity earnings from our 50% investment in Rocky Road		7,174
Total	$	22,392

For the nine months ended September 30, 2005, our historical equity earnings from WCP have been higher than 50% of WCP’s reported net income. As described in Note 13 to our annual financial statements as of and for the year ended December 31, 2004 as amended in a current report on Form 8-K filed on December 20, 2005, our investment in WCP reflected an intangible asset with a one year remaining life, consisting of the value of WCP’s CDWR energy sales contract that expired on December 31, 2004 and a reduction in the value of WCP’s fixed assets that was established when we emerged from bankruptcy on December 6, 2003. The effect on equity earnings due to the intangible asset expired on December 31, 2004. However, NRG’s equity earnings were adjusted during the nine months ended September 30, 2004 by decreasing WCP’s depreciation expense by approximately $9 million to reflect the new basis of their fixed assets.

(14)	On a pro forma basis we have assumed the payment of cash to Dynegy of $160 million was paid as of January 1, 2004. This adjustment reflects the decrease in interest income due to a reduced cash balance based on an average annual interest rate of 3.2%.
(15)	Reflects the tax effect for both the total pro forma “Income from continuing operations before income tax” for the WCP Acquisition of $9.7 million and WCP’s pass-through earnings of $10.8 million, multiplied by an effective tax rate of 39.5%.
(16)	On a pro forma basis we have assumed that the reduction in cash due to the Refinancing and Acquisition of $269.2 million and $335.2 million, respectively (a total of $604.4 million), was paid as of January 1, 2004. This adjustment reflects the decrease in interest income due to a reduced cash balance based on an average annual interest rate of 3.2%.

Supplementary information:

Sensitivity analysis for adjustable rate financing— as part of the refinancing, part of the new term loan and unsecured notes in the amount of $300 million will be subject to an adjustable rate of interest. For the nine months ended September 30, 2005, on a pro forma basis, if the interest rate would increase or decrease by 1/8% for the entire period, income from continuing operations would increase or decrease by $0.6 million, respectively. Also see the sensitivity analysis discussion above – “Sensitivity Analysis for the preliminary pricing of our common stock, new debt instruments and Mandatorily Convertible Preferred Stock”.

Actual results may differ considerably from these pro forma assumptions.

(10) As described in Note 13 to our financial statements filed on Form 10-K for the year ended December 31, 2004, our investment in WCP reflected an intangible asset with a one year remaining life, consisting of the value of WCP’s CDWR energy sales contract that expired on December 31, 2004. This intangible asset was established when we emerged from bankruptcy on December 6, 2003. Assuming we would have purchased the remaining 50% in WCP as of January 1, 2004 we would have established an intangible asset for the entire CDWR energy sales contract of approximately $115.8 million. This intangible asset should be amortized and would reduce WCP’s revenue until the expiration of the CDWR energy sales contract that will occur on December 31, 2004. On a pro forma basis, the entire intangible asset has been amortized during the year ended December 31, 2004, reducing WCP’s revenue by $115.8 million.

(11)	Due to the step-up in value of emission credits pursuant to the WCP Acquisition, this amount reflects the additional amortization expense of emission credits of $1.8 million. This additional expense was derived from the actual amount of credits used during this period by WCP.
(12)	Reflects the decrease in depreciation expense due to the reduction in the value of fixed assets at the acquisition of WCP. This reduction in the value of fixed assets is due to the WCP Acquisition as well as the reduction in the value of fixed assets as reflected in NRG’s carrying value of it’s equity investment in WCP. Also see footnote 24 to the pro forma balance sheet as of September 30, 2005 for further discussion. We have assumed an average remaining useful life of 6 years of the fixed assets acquired, rendering a pro forma decrease in depreciation expense. The remaining useful life of 6 years is based on preliminary estimates based on the latest available information. This assumption may change based on the final appraisal of WCP.
(13)	Reflects the reduction in equity earnings in unconsolidated affiliates assuming WCP was a wholly owned subsidiary as of January 1, 2004 and that we no longer owned a 50% interest in Rocky Road. The reduction in equity earnings from these investments is as follows:

Equity earnings from our 50% investment in WCP	$	68,895
Equity earnings from our 50% investment in Rocky Road LLC		6,904

For the year ended December 31, 2004, our historical equity earnings from WCP have been lower than 50% of WCP’s reported net income. As described in Note 13 to our annual financial statements as of and for the year ended December 31, 2004 as amended in a current report on Form 8-K filed on December 20, 2005, our investment in WCP reflected an intangible asset with a one year remaining life, consisting of the value of WCP’s CDWR energy sales contract that expired on December 31, 2004 and a reduction in the value of WCP’s fixed assets that was established when we emerged from bankruptcy on December 6, 2003. NRG’s equity earnings were significantly decreased due to the amortization of this intangible asset in the amount of $115.8 million during the year ended December 31, 2004. This decrease was slightly offset by the reduction of WCP’s depreciation expense in the amount of $31.7 million to reflect the new basis of their fixed assets.

(14) On a pro forma basis we have assumed the payment of cash to Dynegy of $160 million was paid as of January 1, 2004. This adjustment reflects the decrease in interest income due to a reduced cash balance based on an average annual interest rate of 1.5%.

(15) Reflects the tax effect for both the total pro forma “Loss from continuing operations before income tax” for the WCP Acquisition of $146.1 million and WCP’s pass-through earnings of $305.9 million, multiplied by an effective tax rate of 39.5%.

(16) On a pro forma basis we have assumed that the reduction in cash due to the Refinancing and Acquisition of $269.2 million and $335.2 million, respectively (a total of $604.4 million), was paid as of January 1, 2004. This adjustment reflects the decrease in interest income due to a reduced cash balance based on an average annual interest rate of 1.5%.

Supplementary information:

Sensitivity analysis for adjustable rate financing— as part of the refinancing, part of the new term loan and unsecured notes in the amount of $300 million will be subject to adjustable rate of interest. For the year ended December 31, 2004, on a pro forma basis, if the interest rate would increase or decrease by 1/8% for the entire year, income from continuing operations would increase or decrease by $1.4 million, respectively. Also see the sensitivity analysis discussion above – “Sensitivity Analysis for the preliminary pricing of our common stock, new debt instruments and Mandatorily Convertible Preferred Stock”.

Footnotes to Pro Forma Combined Earnings per Share for the Nine Months Ended September 30, 2005

(1)	The Pro Forma Combined Texas Genco LLC Statement of Operations for the Nine Months Ended September 30, 2005 can be found in Exhibit 99.10.
(2)	On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with AmerenUE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation.
(3)	Reflects pro forma results of an additional 13.2% interest in STP acquired in the ROFR for the period from January 1, 2005 until ROFR acquisition date on May 19, 2005.
(4)	On a pro forma basis it is assumed that 6% Mandatorily Convertible Preferred Shares have been issued and outstanding as of January 1, 2004. As such, for the nine months ended September 30, 2005, there is an increase in dividends for preferred dividend of 22,500.

The 4% Convertible Perpetual Preferred Shares have been issued and outstanding for the entire nine month period ended September 30, 2005 and are already reflected in the historical NRG Earnings per Share calculation.

(5) This increase in the number of weighted average shares is for shares issued to the public, and for the shares issued to the Sellers:

Shares issued to the Sellers — new issuance	35,406
Shares issued to the public	23,474
Total increase in number of weighted average shares	58,880

It should be noted that for pro forma purposes we have assumed that all the shares issued to the Sellers are newly issued. Per the Acquisition Agreement 19,346,788 shares will be issued from treasury, however, on a pro forma basis that is not possible from January 1, 2004 as there were no shares in treasury. For this reason, the weighted average number of common shares outstanding for the nine months ended September 30, 2005 are also higher than what is expected after the closing of the Acquisition.

(6) This increase in the add back for preferred stock dividends is due to the following dilutive preferred stocks:

Dividend for 4% Convertible Perpetual Preferred Shares	12,600
Dividend for 6% Mandatorily Convertible Preferred Shares	22,500
Total Preferred Dividend	35,100

On a pro-forma basis, these items are dilutive.

On December 27, 2005, NRG entered into purchase and sale agreements for projects co-owned with Dynegy. Under the agreements, NRG will acquire Dynegy’s 50% ownership interest in WCP, and become the sole owner of WCP’s 1,808 MW of generation in Southern California. In addition, NRG is selling to Dynegy its 50% ownership interest in Rocky Road, a 330 MW gas-fueled, simple cycle peaking plant located in Dundee, Illinois. Both of these transactions are conditioned upon one another and NRG will pay Dynegy a net purchase price of $160 million at closing. NRG will fund the net purchase price with cash held by the WCP partnership. NRG anticipates closing both transactions during the first quarter 2006.
