Affiliates of Credit Suisse Securities (USA) LLC, the underwriter in this offering, to whom we refer as the CS transaction counterparties, are collectively selling shares of our common stock, par value $0.01 per share, with an aggregate public offering price of up to $500,000,000 under this prospectus supplement through Credit Suisse Securities (USA) LLC, or CSS, in connection with their hedging of certain option-based transactions, which we refer to as the CS transactions, between the CS transaction counterparties and our wholly-owned subsidiaries NRG Common Stock Finance I LLC, which we refer to as NRG CSF I, and NRG Common Stock Finance II LLC, which we refer to as NRG CSF II. We collectively refer to NRG CSF I and NRG CSF II as the CSF subsidiaries. The CS transaction counterparties are offering the shares through Credit Suisse Securities (USA) LLC from time to time for sale in transactions, including block sales, on the New York Stock Exchange, in the over-the-counter market, in negotiated transactions or otherwise. These shares will be sold at market prices prevailing at the time of sale on the New York Stock Exchange or at negotiated prices. The CS transaction counterparties will borrow the shares to be sold under this prospectus supplement from one or more third-party share lenders. We will not receive any proceeds from the sale of shares of our common stock by the CS transaction counterparties.
 
The CSF subsidiaries intend to use up to $500,000,000 to purchase shares of our common stock in the open market or in privately negotiated transactions from time to time during the offering of common stock under this prospectus supplement, including on and prior to the dates on which shares are sold in this offering. To fund such purchases, the CSF subsidiaries will receive proceeds from the transactions from the CS transaction counterparties, as well as an equity contribution from NRG. In addition, over the same period that the shares offered by this prospectus supplement are sold, CSS or its affiliates expect to purchase additional shares of our common stock in the open market in connection with the hedging activities of the CS transaction counterparties. These purchases by the CSF subsidiaries and by CSS and its affiliates could have the effect of materially increasing the market price of our common stock above the price that would otherwise prevail. For more information, see “The CS Transactions.”
 
Our common stock is listed on the New York Stock Exchange under the symbol “NRG.” The last reported closing price of shares of our common stock on the New York Stock Exchange on August 4, 2006 was $47.00.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the prospectus to which it relates is truthful or complete. Any representation to the contrary is a criminal offense.

PROSPECTUS SUMMARY
 
This summary does not contain all of the information that you should consider before investing in our common stock. You should read the entire prospectus supplement and the accompanying prospectus carefully, including the matters discussed under the captions “Risk Factors” and the detailed information and financial statements included or incorporated by reference in this prospectus supplement and the accompanying prospectus. When used in this prospectus supplement, the terms “NRG,” “we,” “our” and “us,” except as otherwise indicated or as the context otherwise indicates, refer to NRG Energy, Inc. and its consolidated subsidiaries.
 
Company Overview
 
NRG Energy is a wholesale power generation company, primarily engaged in the ownership and operation of power generation facilities, the transacting in and trading of fuel and transportation services and the marketing and trading of energy, capacity and related products in the United States and internationally. We have a diverse portfolio of electric generation facilities in terms of geography, fuel type and dispatch levels. Our principal domestic generation assets consist of a diversified mix of natural gas-, coal-, oil-fired and nuclear facilities, representing approximately 45%, 34%, 16% and 5% of our total domestic generation capacity, respectively. In addition, 10% of our domestic generating facilities have dual or multiple fuel capacity, which allows plants to dispatch with the lowest cost fuel option.
 
Our Strategy
 
Our strategy is to optimize the value of our generation assets while using that asset base as a platform for enhanced financial performance which can be sustained and expanded upon in years to come. We plan to maintain and enhance our position as a leading wholesale power generation company in the United States in a cost effective and risk-mitigating manner in order to serve the bulk power requirements of our customer base and other entities that offer load, or otherwise consume wholesale electricity products and services in bulk. Our strategy includes the following elements:
 
Increase value from our existing assets.  We have a highly diversified portfolio of power generation assets in terms of region, fuel type and dispatch levels. We will continue to focus on extracting value from our portfolio by improving plant performance, reducing costs and harnessing our advantages of scale in the procurement of fuels, and in so doing to improve our return on invested capital, or ROIC: a strategy that we have branded “FORNRG,” or Focus on ROIC at NRG.
 
Pursue intrinsic growth opportunities at existing sites in our core regions.  We are favorably positioned to pursue growth opportunities through expansion of our existing generating capacity. We intend to invest in our existing assets through plant improvements, repowering and brownfield development to meet anticipated regional requirements for new capacity. We expect that these efforts will provide more efficient energy, lower our delivered cost, expand our electricity production capability and improve our ability to dispatch economically across all sections of the merit order, including baseload, intermediate and peaking generation.
 
Maintain financial strength and flexibility.  We remain focused on increasing cash flow and maintaining appropriate levels of liquidity, debt and equity in order to ensure continued access to capital for investment, enhancing risk-adjusted returns, and providing flexibility in executing our business strategy. We will continue our focus on maintaining operational and financial controls designed to ensure that our financial position remains strong.
 
Reduce the volatility of our cash flows through asset-based commodity hedging activities.  We will continue to execute asset-based risk management, hedging, marketing and trading strategies within well-defined risk and liquidity guidelines in order to manage the value of our physical and contractual assets. Our marketing and hedging philosophy is centered on generating stable returns from our base load portfolio of power generation assets while preserving the ability to capitalize on strong spot market conditions and to capture the extrinsic value of our intermediate, peaking and portions of our base load

fleet. We believe that we can successfully execute this strategy by taking advantage of our expertise in marketing power and ancillary services, our knowledge of markets, our balanced financial structure and our diverse portfolio of power generation assets.
 
Participate in continued industry consolidation.  We will continue to pursue selective acquisitions, joint ventures and divestitures to enhance our asset mix and competitive position in our core regions in order to meet the fuel and dispatch requirements in these regions. We intend to concentrate on opportunities that we believe will present attractive risk-adjusted returns. We will also opportunistically pursue other strategic transactions, including mergers, acquisitions or divestitures during the consolidation of the power generation industry in the United States.
 
We were incorporated as a Delaware corporation on May 29, 1992.

THE OFFERING
 
Common Stock the CS Transaction Counterparties are Offering Shares of our common stock with an aggregate public offering price of up to $500,000,000 that the CS transaction counterparties are offering through CSS from time to time for sale in transactions, including block sales, on the New York Stock Exchange, in the over the counter market, in negotiated transactions or otherwise. The CS transaction counterparties will borrow the shares to be sold under this prospectus supplement from one or more third-party share lenders.
 
Use of Proceeds We will not receive any proceeds from the sale of shares of our common stock by the CS transaction counterparties pursuant to this prospectus. The CSF subsidiaries will receive proceeds from the sale of the notes and preferred interests to the CS transaction counterparties in connection with the CS transactions, together with the proceeds of an equity contribution from NRG, each as described in “The CS Transactions.” The aggregate proceeds of the CS transactions and the equity contribution is expected to be approximately $500,000,000. The CSF subsidiaries will use those proceeds to purchase shares of our common stock in the open market or in privately negotiated transactions from time to time. Please see “Use of Proceeds” and “The CS Transactions.”

RISK FACTORS
 
Investing in our common stock involves a high degree of risk. In addition to the risk factors set forth below, please see the risk factors described in our Annual Report on Form 10-K for our most recent fiscal year, which are incorporated by reference into this prospectus. Such risks are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business operations. The risks described could affect our business, financial condition or results of operations. In such a case, you may lose all or part of your original investment. You should carefully consider the risks described in our Form 10-K, the risks described below as well as other information and data set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before making an investment decision with respect to the common stock.
 
Risks Related to this Offering
 
The price of our common stock may fluctuate significantly, which may make it difficult for you to resell the common stock when you want or at prices you find attractive.
 
The price of our common stock on the New York Stock Exchange constantly changes. We expect that the market price of our common stock will continue to fluctuate. Holders of our common stock will be subject to the risk of volatility and depressed prices.
 
Our common stock price can fluctuate as a result of a variety of factors, many of which are beyond our control. These factors include:
 
  •  new laws or regulations or new interpretations of existing laws or regulations applicable to our business;
 
  •  changes in accounting standards, policies, guidance, interpretations or principles;
 
  •  our ability to raise additional capital;
 
  •  sales of common stock by us or members of our management team;
 
  •  quarterly variations in our operating results;
 
  •  operating results that vary from the expectations of management, securities analysts and investors;
 
  •  changes in expectations as to our future financial performance, including financial estimates by securities analysts and investors;
 
  •  developments generally affecting our industry;
 
  •  market activities taken by the CS transaction counterparties and their affiliates after the conclusion of this offering;
 
  •  announcements by us or our competitors of significant contracts, acquisitions, joint marketing relationships, joint ventures or capital commitments;
 
  •  announcements by third parties of significant claims or proceedings against us;
 
  •  changes in our dividend policy;
 
  •  future sales of our equity or equity-linked securities; and
 
  •  general domestic and international economic conditions.
 
In addition, the stock market in general has experienced extreme volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations may adversely affect the market price of our common stock.

Our ability to pay dividends may be limited.
 
The terms of our senior secured credit facility and the indentures governing our senior notes restrict our ability to pay dividends to the holders of our common stock. In addition, under the terms of our outstanding preferred stock, we are restricted from paying any cash dividend on our common stock if we are not current in our dividend payments with respect to such preferred stock. In the future, we may agree to further restrictions on our ability to pay dividends. In addition, to maintain our credit ratings, we may be limited in our ability to pay dividends so that we can maintain an appropriate level of debt. Our future dividend policy depends on earnings, financial condition, liquidity, capital requirements and other factors. There is no guarantee that we will pay dividends on shares of our common stock.
 
Our corporate documents and Delaware law contain provisions that could discourage, delay or prevent a change in control of our company even if some stockholders might consider such a development favorable, which may adversely affect the price of our common stock.
 
Provisions in our amended and restated certificate of incorporation and amended and restated by-laws may discourage, delay or prevent a merger or acquisition involving us that our stockholders may consider favorable. For example, our amended and restated certificate of incorporation authorizes our board of directors to issue shares of preferred stock to which special rights are attached, including voting and dividend rights. With these rights, preferred stockholders could make it more difficult for a third party to acquire us. In addition, our amended and restated certificate of incorporation provides for a staggered board of directors, whereby directors serve for three-year terms, with approximately one third of the directors coming up for reelection each year. Having a staggered board of directors would make it more difficult for a third party to obtain control of our board of directors through a proxy contest, which may be a necessary step in an acquisition of us that is not favored by our board of directors.
 
We are also subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law. Under these provisions, if anyone becomes an “interested stockholder,” we may not enter into a “business combination” with that person for three years without special approval, which could discourage a third party from making a takeover offer and could delay or prevent a change of control. For purposes of Section 203, “interested stockholder” means, generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the past three years, subject to certain exceptions as described in Section 203.
 
Under our senior secured credit facility, a change of control is an event of default. Upon the occurrence of a change in control, the holders of our senior notes will have the right, subject to certain conditions, to require us to repurchase their notes at a price equal to 101% of their principal amount plus accrued and unpaid interest and liquidated damages, if any, to the date of repurchase.
 
Shares eligible for future issuance or sale may cause our common stock price to decline, which may negatively impact your investment.
 
Issuances or sales of substantial numbers of additional shares of our common stock, including in connection with future acquisitions, if any, or the perception that such issuances or sales could occur, may cause prevailing market prices for shares of our common stock to decline and may adversely affect our ability to raise additional capital in the financial markets at a time and price favorable to us. As of the date of this prospectus supplement, our amended and restated certificate of incorporation provides that we have authority to issue up to 500,000,000 shares of our common stock. As of August 2, 2006, 137,015,810 shares of our common stock were issued and outstanding and no shares of our common stock were issued and held in treasury. Also as of such date, there were 39,307,003 shares of our common stock reserved for issuance with respect to convertible preferred stock and under stock incentive plans or pursuant to individual option grants or stock awards. Future sales or a perception that such sales may occur could reduce the market price for our common stock.

The market price of our common stock may be higher than that which would otherwise prevail as a result of the purchases of our common stock by the CSF subsidiaries and by CSS and its affiliates.
 
The CSF subsidiaries intend to use up to $500,000,000 to purchase shares of our common stock in the open market or in privately negotiated transactions from time to time during the offering of common stock under this prospectus supplement, including on and prior to the dates on which shares are sold in this offering. To fund such purchases, the CSF subsidiaries will receive proceeds from the sale of the notes and preferred interests to the CS transaction counterparties in connection with the CS transactions, as well as an equity contribution from NRG. In addition, over the same period that the shares offered by those prospectus supplement are sold, CSS or its affiliates expect to purchase additional shares of our common stock in the open market in connection with the hedging activities of the CS transaction counterparties. These purchases by the CSF subsidiaries and by CSS and its affiliates could have the effect of materially increasing the market price of our common stock above the price that would otherwise prevail.

USE OF PROCEEDS
 
We will not receive any proceeds from the sale of shares of our common stock by the CS transaction counterparties pursuant to this prospectus supplement. Sales of our common stock through this prospectus supplement by the CS transaction counterparties are being made pursuant to a hedging program instituted in connection with their investment in the CSF subsidiaries pursuant to the CS transactions.
 
The CSF subsidiaries will receive proceeds from the sale of notes and preferred interests to the CS transaction counterparties in connection with the CS transactions, together with the proceeds of an equity contribution from NRG, each as described in “The CS Transactions.” The aggregate proceeds of the CS transactions and the equity contribution is expected to be approximately $500,000,000. The CSF subsidiaries will use those proceeds to purchase shares of our common stock in the open market or in privately negotiated transactions from time to time. We expect that the CSF subsidiaries will be consolidated in our financial statements. We also expect the proceeds to be received by the CSF subsidiaries from the CS transactions will be reflected as debt on our consolidated balance sheet. Our shares of common stock to be purchased by the CSF subsidiaries are expected to be reflected as treasury stock, at cost, reducing shareholders equity on our consolidated balance sheet and reducing the number of outstanding shares of our common stock. In addition, there will be a reduction to our weighted average number of shares outstanding as disclosed in our statement of operations. These purchases by the CSF subsidiaries could have the effect of materially increasing the market price of our common stock above the price that would otherwise prevail.

THE CS TRANSACTIONS
 
During a period beginning on the date of this prospectus supplement, the CSF subsidiaries will use up to $500,000,000 to purchase shares of our common stock in the open market or in privately negotiated transactions from time to time. That period of time, which we refer to as the reference period, is expected to be complete when the CSF subsidiaries have paid an aggregate of $500,000,000 in connection with such purchases. The CSF subsidiaries will make such purchases using the proceeds of the CS transactions, as well as an equity contribution from NRG, which is expected to be approximately $166,000,000. The CS transaction counterparties will make payments to the CSF subsidiaries pursuant to the CS transactions over the reference period as the CSF subsidiaries make purchases of our common stock. These purchases by the CSF subsidiaries, together with purchases by CSS and its affiliates, could have the effect of materially increasing the market price of our common stock above the price that would otherwise prevail.
 
We expect that the CSF subsidiaries will be consolidated in our financial statements. As such, we expect the proceeds from the CS transactions, which are expected to total approximately $334,000,000, will be reflected as debt on our consolidated balance sheet. Our shares of common stock held by the CSF subsidiaries are expected to be reflected as treasury stock on our consolidated balance sheet at cost and will reduce the number of outstanding shares. In addition, there will be a reduction to our weighted average number of shares outstanding as disclosed in our statement of operations.
 
The CS transactions entered into by NRG CSF I will have a term of approximately two years and the CS transactions entered into by NRG CSF II will have a term of approximately three years. At maturity of the CS transactions, the CSF subsidiaries will be obligated to pay the CS transaction counterparties a stated amount in cash. In addition, at maturity the CS transaction counterparties will have the right to exchange the preferred interests and notes they purchased in the CS transactions for an additional payment equal to the excess, if any, of the market value of our common stock owned by each CSF subsidiary over a threshold amount. A portion of the CS transactions entered into by each CSF subsidiary will be secured by all of the assets of that CSF subsidiary, consisting primarily in both cases of the shares of our common stock purchased by that CSF subsidiary during the reference period. The CS transactions are non-recourse to NRG. We will not guarantee or provide any form of credit support to the CSF subsidiaries, and we will not enter into any agreement, contract, arrangement or understanding with the CSF subsidiaries with respect thereto.
 
Upon an event of default or certain specified termination events, the fair value of the CS transactions (including the exchange right) will become due and payable by the CSF subsidiaries to the CS transaction counterparties. In addition, the CSF subsidiaries will have the right to unwind the CS transactions at their fair value at any time.
 
Although the obligations of the CSF subsidiaries to the CS transaction counterparties are non-recourse to NRG, it is anticipated that NRG will purchase the common stock held by the CSF subsidiaries at maturity for a price sufficient both to pay all amounts owing to the CS transaction counterparties at maturity and to enable the CSF subsidiaries to return all equity contributions received from NRG.
 
As a result of the exchange right described above, the CS transactions are option-based transactions. The CS transaction counterparties will sell shares of our common stock covered by this prospectus supplement in connection with hedging the equity price risk arising from the CS transactions. The documents relating to the CS transactions will contain customary anti-dilution adjustments and adjustments for payments of dividends on our common stock or certain increased costs to the CS transaction counterparties.
 
If the CSF subsidiaries do not complete the purchase of $500,000,000 of our common stock during the reference period, or if the CS transaction counterparties do not introduce the full number of shares underlying the CS transactions into the public markets pursuant to this prospectus supplement, the size of the CS transactions (including the payment amounts and the number of underlying shares for the CS transactions) will be reduced proportionally. The CSF subsidiaries are not obligated to complete any additional purchases of our common stock. As a result, we cannot assure you that any additional shares will be purchased by the CSF subsidiaries in the future.

MATERIAL UNITED STATES TAX CONSIDERATIONS TO NON-U.S. HOLDERS
 
The following is a general discussion of the material U.S. federal income and estate tax considerations applicable to non-U.S. holders with respect to their ownership and disposition of shares of our common stock. This discussion is for general information only and is not tax advice. Accordingly, all prospective non-U.S. holders of our common stock should consult their own tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the acquisition, ownership and disposition of our common stock. A “non-U.S. holder” means a beneficial owner of our common stock who is not for U.S. federal income tax purposes:
 
  •  an individual citizen or resident of the United States,
 
  •  a corporation, partnership, or any other organization taxable for U.S. federal income tax purposes as a corporation or partnership created or organized in the United States or under the laws of the United States, any state thereof, or the District of Columbia,
 
  •  an estate the income of which is included in gross income for U.S. federal income tax purposes regardless of its source, or
 
  •  a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) a valid election is in place to treat the trust as a U.S. person.
 
This discussion is based on current provisions of the United States Internal Revenue Code of 1986, as amended, existing and proposed United States Treasury Regulations promulgated thereunder, current administrative rulings and judicial decisions, all of which are in effect as of the date of this prospectus and all of which are subject to change, potentially with retroactive effect, or to differing interpretation. Any change, which may or may not be retroactive, could alter the tax consequences to non-U.S. holders described in this prospectus. We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset (generally property held for investment).
 
This discussion does not address all aspects of U.S. federal income and estate taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances nor does it address any aspects of U.S. state, local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, including but not limited to:
 
  •  banks, insurance companies, or other financial institutions;
 
  •  tax-exempt organizations;
 
  •  controlled foreign corporations or passive foreign investment companies;
 
  •  brokers or dealers in securities or currencies;
 
  •  pass-through entities (e.g. partnerships) or persons who hold our common stock through pass-through entities;
 
  •  regulated investment companies;
 
  •  pension plans;
 
  •  owners of more than 5% of our common stock;
 
  •  persons that hold our common stock as part of a straddle, hedge, conversion transaction, synthetic security or other integrated investment; and
 
  •  certain U.S. expatriates.
 
In addition, if a partnership holds our common stock, the tax treatment of a partner generally will depend on the status of the partner and upon the activities of the partnership. Accordingly, partnerships that are prospective investors in our common stock, and partners in such partnerships, should consult their tax advisors.

Table of Contents

There can be no assurance that the Internal Revenue Service, or the IRS, will not challenge one of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, an opinion of counsel with respect to the U.S. federal income or estate tax consequences to a non-U.S. holder of the purchase, ownership, or disposition of our common stock. We urge prospective investors to consult with their own tax advisors regarding the U.S. federal, state, local and non-U.S. income and other tax considerations of acquiring, holding and disposing of shares of our common stock.
 
The following does not attempt to characterize or discuss the tax issues and/or ramifications, if any, resulting from the CSF subsidiaries’ transactions outlined herein, including any disposition of shares of NRG common stock by the CSF subsidiaries.
 
Distributions on Our Common Stock
 
NRG has not declared or paid distributions on its common stock, although, subject to certain restrictions, we may do so in the future. In the event we do pay distributions on our common stock, these distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s tax basis in the common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below in “Gain on Sale or Other Disposition of Our Common Stock.”
 
Dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be provided by an applicable income tax treaty. If we determine, at a time reasonably close to the date of payment of a distribution on our common stock, that the distribution will not qualify as a dividend because we do not anticipate having current or accumulated earnings and profits, we intend not to withhold any U.S. federal income tax on the distribution as permitted by United States Treasury Regulations. If we or another withholding agent withholds tax on such a distribution, a non-U.S. holder may be entitled to a refund of the tax withheld which the non-U.S. holder may claim by filing a United States tax return with the IRS.
 
Dividends that are treated as “effectively connected” with a trade or business conducted by a non-U.S. holder within the United States (and, if an applicable income tax treaty so provides, are also attributable to a permanent establishment of such non-U.S. holder), known as “United States trade or business income,” are generally exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and other requirements. However, such United States trade or business income, net of specified deductions and credits, is taxed at the same graduated U.S. federal income tax rates applicable to United States persons and may be subject to state and local tax. Any United States trade or business income received by a non-U.S. holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as specified by an applicable income tax treaty.
 
A non-U.S. holder of our common stock who claims the benefit of an applicable income tax treaty generally will be required to satisfy applicable certification and other requirements. Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty and any potential impacts to state and local income taxes.
 
A non-U.S. holder that is eligible for a reduced rate of United States withholding tax or other exclusion from withholding under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim with the IRS.
 
Gain on Sale or Other Disposition of Our Common Stock
 
In general, a non-U.S. holder will not be subject to any U.S. federal income tax or withholding tax on any gain realized upon such holder’s sale or other disposition of shares of our common stock unless:
 
  •  the gain is United States trade or business income, in which case such holder (i) will be subject to tax on the net gain derived from the sale or disposition under the graduated United States federal


S-10


Table of Contents

  income tax rates applicable to United States persons and (ii) if a corporation, may be subject to the branch profits tax, both as described above in “Distributions on Our Common Stock;”
 
  •  the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and meets certain other requirements in which case the holder will be subject to a flat 30% tax on the amount by which the gain derived from the sale, and certain other United States source capital gains realized during such year exceed certain United States source capital losses realized during such year; or
 
  •  certain rules (described below) relating to “United States real property holding corporation” status apply to such sale or other disposition.
 
Gain recognized on a sale or other disposition of our common stock may be subject to U.S. federal income tax (and, in certain circumstances, to withholding tax) if (1) our common stock has ceased to be traded on an established securities market prior to the beginning of the calendar year in which the sale or disposition occurs and (2) we are, or have been, a United States real property holding corporation during the shorter of the five-year period ending on the date of such sale or other disposition or the period that the non-U.S. holder held our common stock. Generally, a corporation is a United States real property holding corporation if the fair market value of its “United States real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance, we do not believe that we are, or have been, a United States real property holding corporation, or that we are likely to become one in the future.
 
United States Federal Estate Tax
 
Shares of our common stock that are owned or treated as owned by an individual non-U.S. holder at the time of death will be included in the individual’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax or other treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.
 
Backup Withholding, Information Reporting and Other Reporting Requirements
 
We must report to the IRS and to each non-U.S. holder the gross amount of the dividends on our common stock paid to such holder and the tax withheld, if any, with respect to such dividends. Dividends paid to non-U.S. holders subject to the United States withholding tax, as described above in “Distributions on Our Common Stock,” generally will be exempt from United States backup withholding.
 
Information reporting and backup withholding (currently at a rate of 28%) will generally apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the United States office of a broker unless the holder certifies its status as a non-U.S. holder and satisfies certain other qualifications, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds where the transaction is effected outside the United States through a non-U.S. office of a non-U.S. broker. However, for information reporting purposes, certain brokers with substantial United States ownership or operations generally will be treated in a manner similar to United States brokers. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.
 
Copies of information returns may be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is incorporated.
 
Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder’s U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

PLAN OF DISTRIBUTION
 
The CS transaction counterparties are offering shares of our common stock with an aggregate public offering price of up to $500,000,000 under this prospectus supplement, which the CS transaction counterparties will borrow from one or more third-party share lenders and which will be sold by the CS transaction counterparties through Credit Suisse Securities (USA) LLC, the underwriter in this offering, in connection with their hedging of the CS transactions between the CS transaction counterparties and the CSF subsidiaries. The CS transaction counterparties, through Credit Suisse Securities (USA) LLC will sell, from time to time, these shares in transactions, including block sales, on the New York Stock Exchange, in the over the counter market, in negotiated transactions or otherwise. These shares will be sold at market prices prevailing at the time of sale or at negotiated prices. In connection with the sale of these shares, Credit Suisse Securities (USA) LLC may effect such transactions by selling the shares to or through dealers, and these dealers may receive compensation in the form of discounts, concessions or commissions from Credit Suisse Securities (USA) LLC and/or from purchasers of shares for whom the dealers may act as agents or to whom they may sell as principals. In addition, over the same period that shares are sold in this offering, CSS or its affiliates expect to purchase shares of our common stock in the open market. These purchases could also have a material effect on the market price of our common stock.
 
After the conclusion of the offering, the CS transaction counterparties and their affiliates may also buy or sell additional common stock or other securities or buy or sell options or futures contracts or enter into swaps or other derivatives in order to adjust their respective hedge positions with respect to the CS transactions, and these activities may be significant, particularly at or around the maturity of the transactions. The CS transaction counterparties and their affiliates may also be active in the market for our common stock other than in connection with hedging activities in relation to the CS transactions. The CS transaction counterparties and their affiliates will make their own determinations as to whether, when or in what manner any hedging or market activities in our securities will be conducted. Any of these market activities may affect the market price and volatility of shares of our common stock.
 
Our common stock is listed on the New York Stock Exchange under the symbol “NRG.”
 
We have agreed, with exceptions, not to sell or transfer any of our common stock for 60 days after each date that shares are sold pursuant to this prospectus supplement without first obtaining written consent of Credit Suisse Securities (USA) LLC.
 
We estimate that our portion of the total expenses of this offering will be approximately $110,000.
 
The underwriter and its affiliates have performed investment banking, banking and/or advisory services for us from time to time for which they have received customary fees and expenses. On August 11, 2005, an affiliate of the underwriter purchased 250,000 shares of our 3.625% Preferred Stock, with a liquidation preference of $1,000 per share, for a gross purchase price of $250 million. The underwriter and its affiliates may, from time to time, engage in other transactions with and perform other services for us in the ordinary course of business.
 
A prospectus in electronic format may be made available on the website maintained by the underwriter. In addition, shares may be sold by the underwriter to securities dealers who resell shares to online brokerage account holders.
 
We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriter may be required to make because of any of those liabilities.
 
Because more than 10% of the net proceeds of the offering of the initial hedge shares and the supplemental hedge shares will be paid to an affiliate of a member of the NASD who is participating in the offering, the offering of these shares is being conducted in compliance with Rule 2710(h) of the NASD. Pursuant to NASD Conduct Rules, the appointment of a qualified independent underwriter is not necessary in connection with this offering, as a bona fide independent market (as defined in the NASD Conduct Rules) exists in our common stock.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
 
This prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Such forward-looking statements are subject to certain risks, uncertainties and assumptions that include, but are not limited to, expected earnings and cash flows, future growth and financial performance and the expected synergies and other benefits of the acquisition of Texas Genco LLC described herein (including the documents incorporated herein by reference), and typically can be identified by the use of words such as “will,” “expect,” “estimate,” “anticipate,” “forecast,” “plan,” “believe” and similar terms. Although we believe that our expectations are reasonable, we can give no assurance that these expectations will prove to have been correct, and actual results may vary materially. Factors that could cause actual results to differ materially from those contemplated above include, among others:
 
  •  Risks and uncertainties related to the capital markets generally, including increases in interest rates and the availability of financing for the acquisition of Texas Genco LLC;
 
  •  NRG’s indebtedness and the additional indebtedness that it will incur in connection with the acquisition of Texas Genco LLC;
 
  •  NRG’s ability to successfully complete the acquisition of Texas Genco LLC, regulatory or other limitations that may be imposed as a result of the acquisition of Texas Genco LLC, and the success of the business following the acquisition of Texas Genco LLC;
 
  •  General economic conditions, changes in the wholesale power markets and fluctuations in the cost of fuel or other raw materials;
 
  •  Hazards customary to the power production industry and power generation operations such as fuel and electricity price volatility, unusual weather conditions, catastrophic weather-related or other damage to facilities, unscheduled generation outages, maintenance or repairs, unanticipated changes to fossil fuel supply costs or availability due to higher demand, shortages, transportation problems or other developments, environmental incidents, or electric transmission or gas pipeline system constraints and the possibility that we may not have adequate insurance to cover losses as a result of such hazards;
 
  •  NRG’s potential inability to enter into contracts to sell power and procure fuel on terms and prices acceptable to it;
 
  •  The liquidity and competitiveness of wholesale markets for energy commodities;
 
  •  Changes in government regulation, including possible changes of market rules, market structures and design, rates, tariffs, environmental laws and regulations and regulatory compliance requirements;

Table of Contents

  •  Price mitigation strategies and other market structures or designs employed by independent system operators, or ISOs, or regional transmission organizations, or RTOs, that result in a failure to adequately compensate our generation units for all of their costs;
 
  •  NRG’s ability to realize its significant deferred tax assets, including loss carry forwards;
 
  •  The effectiveness of NRG’s risk management policies and procedures and the ability of NRG’s counterparties to satisfy their financial commitments;
 
  •  Counterparties’ collateral demands and other factors affecting NRG’s liquidity position and financial condition;
 
  •  NRG’s ability to operate its businesses efficiently, manage capital expenditures and costs (including general and administrative expenses) tightly and generate earnings and cash flow from its asset-based businesses in relation to its debt and other obligations; and
 
  •  Significant operating and financial restrictions placed on NRG contained in the indenture governing its 8% second priority senior secured notes due 2013, its amended and restated credit facility as well as in debt and other agreements of certain of NRG’s subsidiaries and project affiliates generally.

NRG ENERGY, INC.
 
NRG Energy is a wholesale power generation company, primarily engaged in the ownership and operation of power generation facilities, the transacting in and trading of fuel and transportation services and the marketing and trading of energy, capacity and related products in the United States and internationally. We have a diverse portfolio of electric generation facilities in terms of geography, fuel type and dispatch levels. Our principal domestic generation assets (without giving effect to the acquisition of Texas Genco LLC) consist of a diversified mix of natural gas-, coal- and oil-fired facilities, representing approximately 40%, 30% and 30% of our total domestic generation capacity, respectively. In addition (without giving effect to the acquisition of Texas Genco LLC), approximately 15% of our domestic generating facilities have dual- or multiple-fuel capacity, which render the ability for plants to dispatch with the lowest cost fuel option.
 
Our two principal operating objectives are to optimize performance of our entire portfolio, and to protect and enhance the market value of our physical and contractual assets through the execution of risk management, marketing and trading strategies within well-defined risk and liquidity guidelines. We manage the assets in our core regions on a portfolio basis as integrated businesses in order to maximize profits and minimize risk. Our business involves the reinvestment of capital in our existing assets for reasons of repowering, expansion, pollution control, operating efficiency, reliability programs, greater fuel optionality, greater merit order diversity, and enhanced portfolio effect, among other reasons. Our business also may involve acquisitions intended to complement the asset portfolios in our core regions. From time to time we may also consider and undertake other merger and acquisition transactions that are consistent with our strategy, such as our pending acquisition of Texas Genco LLC.
 
On September 30, 2005, we entered into an acquisition agreement, or the Acquisition Agreement, with Texas Genco LLC and each of the direct and indirect owners of equity interests in Texas Genco LLC, or the Sellers. Pursuant to the Acquisition Agreement, we agreed to purchase all of the outstanding equity interests in Texas Genco LLC for a total purchase price of approximately $5.825 billion and the assumption by us of approximately $2.5 billion of indebtedness. The purchase price is subject to adjustment, and includes an equity component valued at $1.8 billion based on a price per share of $40.50 of NRG’s common stock. As a result of the Acquisition, Texas Genco LLC will become a wholly owned subsidiary of NRG and will nearly double our U.S. generation portfolio from approximately 12,005 Megawatts to 23,124 Megawatts.
 
We were incorporated as a Delaware corporation on May 29, 1992. Our common stock is listed on the New York Stock Exchange under the symbol “NRG”. Our headquarters and principal executive offices are located at 211 Carnegie Center, Princeton, New Jersey 08540. Our telephone number is (609) 524-4500.
 
You can get more information regarding our business by reading our Annual Report on Form 10-K for the fiscal year ended December 31, 2004, and the other reports we file with the Securities and Exchange Commission. See “Where You Can Find More Information.”

DESCRIPTION OF SECURITIES WE MAY OFFER
 
DEBT SECURITIES AND GUARANTEES
 
We may offer secured or unsecured debt securities, which may be convertible. Our debt securities and any related guarantees will be issued under an indenture to be entered into between us and Law Debenture Trust Company of New York. Holders of our indebtedness will be structurally subordinated to holders of any indebtedness (including trade payables) of any of our subsidiaries that do not guarantee our payment obligations under such indebtedness.
 
We have summarized certain general features of the debt securities from the indenture. A form of indenture is attached as an exhibit to the registration statement of which this prospectus forms a part. The following description of the terms of the debt securities and the guarantees sets forth certain general terms and provisions. The particular terms of the debt securities and guarantees offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities and guarantees will be described in the related prospectus supplement. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the related prospectus supplement and to the following description.

One or more series of debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. One or more series of debt securities may be variable rate debt securities that may be exchanged for fixed rate debt securities.
 
United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable prospectus supplement.
 
Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional United States federal income tax considerations will be set forth in the applicable prospectus supplement.
 
The term “debt securities” includes debt securities denominated in U.S. dollars or, if specified in the applicable prospectus supplement, in any other freely transferable currency or units based on or relating to foreign currencies.
 
We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 or $5,000 and any integral multiples thereof. Subject to the limitations provided in the indenture and in the prospectus supplement, debt securities that are issued in registered form may be

transferred or exchanged at the office of the trustee maintained in the Borough of Manhattan, The City of New York or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.
 
Guarantees
 
Any debt securities may be guaranteed by one or more of our direct or indirect subsidiaries. Each prospectus supplement will describe any guarantees for the benefit of the series of debt securities to which it relates, including required financial information of the subsidiary guarantors, as applicable.
 
Global Securities
 
The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary (the “depositary”) identified in the prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.
 
Governing Law
 
The indenture, the debt securities and the guarantees shall be construed in accordance with and governed by the laws of the State of New York, without giving effect to the principles thereof relating to conflicts of law.
 
PREFERRED STOCK
 
The following briefly summarizes the material terms of our preferred stock, other than pricing and related terms that will be disclosed in an accompanying prospectus supplement. You should read the particular terms of any series of preferred stock offered by us, which will be described in more detail in any prospectus supplement relating to such series, together with the more detailed provisions of our amended and restated certificate of incorporation and the certificate of designation relating to each particular series of preferred stock for provisions that may be important to you. The certificate of incorporation, as amended and restated, is incorporated by reference into the registration statement of which this prospectus forms a part. The certificate of designation relating to the particular series of preferred stock offered by an accompanying prospectus supplement and this prospectus will be filed as an exhibit to a document incorporated by reference in the registration statement. The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.
 
As of the date of this prospectus, we are authorized to issue up to 10,000,000 shares of preferred stock, par value $0.01 per share. As of December 16, 2005, 420,000 shares of 4% Convertible Perpetual Preferred Stock were outstanding and 250,000 shares of 3.625% Convertible Perpetual Preferred Stock were outstanding. Under our amended and restated certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series, and to establish from time to time a series of preferred stock with the following terms specified:
 
  •  the number of shares to be included in the series;
 
  •  the designation, powers, preferences and rights of the shares of the series; and
 
  •  the qualifications, limitations or restrictions of such series.

Table of Contents

 
Prior to the issuance of any series of preferred stock, our board of directors will adopt resolutions creating and designating the series as a series of preferred stock and the resolutions will be filed in a certificate of designation as an amendment to the amended and restated certificate of incorporation. The term “board of directors” includes any duly authorized committee.
 
The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future. Our board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our or our subsidiaries’ officers, directors and employees pursuant to benefit plans or otherwise. Shares of preferred stock we issue may have the effect of rendering more difficult or discouraging an acquisition of us deemed undesirable by our board of directors.
 
The preferred stock will be, when issued, fully paid and nonassessable. Holders of preferred stock will not have any preemptive or subscription rights to acquire more of our stock.
 
The transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock will be named in the prospectus supplement relating to such series.
 
Rank
 
Unless otherwise specified in the prospectus supplement relating to the shares of a series of preferred stock, such shares will rank on an equal basis with each other series of preferred stock and prior to the common stock as to dividends and distributions of assets.
 
Dividends
 
Holders of each series of preferred stock will be entitled to receive cash dividends when, as and if declared by our board of directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books or, if applicable, the records of the depositary referred to below on the record dates fixed by the board of directors. Dividends on a series of preferred stock may be cumulative or noncumulative.
 
We may not declare, pay or set apart for payment dividends on the preferred stock unless full dividends on other series of preferred stock that rank on an equal or senior basis have been paid or sufficient funds have been set apart for payment for
 
  •  all prior dividend periods of other series of preferred stock that pay dividends on a cumulative basis; or
 
  •  the immediately preceding dividend period of other series of preferred stock that pay dividends on a noncumulative basis.
 
Partial dividends declared on shares of preferred stock and each other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for each series of preferred stock.
 
Similarly, we may not declare, pay or set apart for payment non-stock dividends or make other payments on the common stock or any other of our stock ranking junior to the preferred stock until full dividends on the preferred stock have been paid or set apart for payment for
 
  •  all prior dividend periods if the preferred stock pays dividends on a cumulative basis; or
 
  •  the immediately preceding dividend period if the preferred stock pays dividends on a noncumulative basis.

Conversion and Exchange
 
The prospectus supplement for a series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for shares of our common stock, our preferred stock, our other securities or the debt or equity securities of one or more other entities.
 
Redemption and Sinking Fund
 
If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or the option of the holder thereof and may be mandatorily redeemed. Any partial redemptions of preferred stock will be made in a way that the board of directors decides is equitable.
 
Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.
 
No series of preferred stock will receive the benefit of a sinking fund except as set forth in the applicable prospectus supplement.
 
Liquidation Preference
 
Upon any voluntary or involuntary liquidation, dissolution or winding up, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Such distributions will be made before any distribution is made on any securities ranking junior relating to liquidation, including common stock.
 
If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of our available assets on a ratable basis in proportion to the full liquidation preferences. Holders of such series of preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.
 
Voting Rights
 
The holders of shares of preferred stock will have no voting rights, except:
 
  •  as otherwise stated in the prospectus supplement;
 
  •  as otherwise stated in the certificate of designation establishing such series; and
 
  •  as required by applicable law.
