There is no existing public market for the Old Notes or the Exchange Notes. We do not intend to list the Exchange Notes on any securities exchange or seek approval for quotation through any automated trading system.

         Neither the SEC nor any state securities commission has approved the notes to be distributed in the exchange offer, nor have any of these organizations determined that this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

         Each broker-dealer that receives Exchange Notes for its own account pursuant to this exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes. The letter of transmittal accompanying this prospectus states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act of 1933, as amended (the "Securities Act"). This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes where the Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, starting on the expiration date and ending on the close of business one year after the expiration date, we will make this prospectus available, as amended or supplemented, to any broker-dealer for use in connection with any such resale.

RISK FACTORS

        You should carefully consider the risk factors set forth below and the risk factors incorporated into this prospectus by reference to our 2017 Form 10-K as well as the other information contained in and incorporated by reference into this prospectus before deciding to participate in this exchange offer. The selected risks described below and the risks that are incorporated into this prospectus by reference to our 2017 Form 10-K are not our only risks. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial also may materially and adversely affect our business, financial condition or results of operations. Any of the following risks or any of the risks described in our 2017 Form 10-K could materially and adversely affect our business, financial condition, operating results or cash flow. In such a case, the trading price of the notes could decline, or we may not be able to make payments of interest and principal on the notes, and you may lose all or part of your original investment.

Risks related to the notes

Credit rating downgrades could adversely affect the trading price of the notes.

        The trading price for the notes may be affected by our credit rating. Credit ratings are continually revised. Any downgrade in our credit rating could adversely affect the trading prices of the notes or the trading markets for the notes to the extent the trading markets for the notes develop.

Despite current indebtedness levels, we may still be able to incur substantially more debt. This could increase the risks associated with our already substantial leverage.

        We may be able to incur substantial additional indebtedness in the future. The terms of the indenture governing the notes and other indentures relating to outstanding indebtedness restrict our ability to do so, but we retain the ability to incur material amounts of additional indebtedness. If new indebtedness is added to our current indebtedness levels, the related risks that we now face could increase. See "Description of Certain Other Indebtedness."

To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.

        Our ability to make payments on and to refinance our indebtedness, including these notes, and to fund planned capital expenditures depends on our ability to generate cash in the future. This, to a significant extent, is subject to general economic, financial, competitive, legislative, tax, regulatory, environmental and other factors that are beyond our control.

        Based on our current level of operations and anticipated cost savings and operating improvements, we believe our cash flow from operations, available cash and available borrowings under our Senior Credit Facility, will be adequate to meet our future liquidity needs for at least the next 12 months.

        We cannot assure you, however, that our business will generate sufficient cash flow from operations, that currently anticipated cost savings and operating improvements will be realized on schedule or at all or that future borrowings will be available to us under our Senior Credit Facility in an amount sufficient to enable us to pay our indebtedness, including the notes, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, including the notes on or before maturity. We cannot assure you that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

In the event of a bankruptcy or insolvency, holders of our secured indebtedness and other secured obligations will have a prior secured claim to any collateral securing such indebtedness or other obligations.

        Holders of our secured indebtedness and other secured obligations will have a prior secured claim to any collateral securing such indebtedness or other obligations. Holders of our secured indebtedness

and the secured indebtedness of the guarantors will have claims that are prior to your claims as holders of the notes to the extent of the value of the assets securing that other indebtedness. Our Senior Credit Facility is secured by first priority liens on substantially all of our assets and the assets of the guarantors. We have granted first and second priority liens on substantially all of our assets to secure our obligations under certain long-term power and gas hedges as well as interest rate hedges. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization, or other bankruptcy proceeding, holders of secured indebtedness will have prior claim to those of our assets that constitute their collateral. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of notes may receive less, ratably, than holders of secured indebtedness.

Your right to receive payments on these notes could be adversely affected if any of our non-guarantor subsidiaries declare bankruptcy, liquidate or reorganize.

        Some, but not all, of our subsidiaries will guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us. As of June 30, 2018, our non-guarantor subsidiaries had approximately $8 billion in aggregate principal amount of non-current liabilities and outstanding trade payables of approximately $230 million. In addition, the indenture governing the notes permits us, subject to certain covenant limitations, to provide credit support for the obligations of the non-guarantor subsidiaries and such credit support may be effectively senior to our obligations under the notes. Further, the indenture governing the notes allows us to transfer assets, including certain specified facilities, to the non-guarantor subsidiaries.

We may not have access to the cash flow and other assets of our subsidiaries that may be needed to make payment on the notes.

        Much of our business is conducted through our subsidiaries. Although certain of our subsidiaries will guarantee the notes, some of our subsidiaries will not become guarantors and thus will not be obligated to make funds available to us for payment on the notes. Our ability to make payments on the notes will be dependent on the earnings and the distribution of funds from subsidiaries, some of which are non-guarantors. Our subsidiaries are permitted under the terms of the indenture to incur additional indebtedness that may restrict or prohibit the making of distributions, the payment of dividends or the making of loans by such subsidiaries to us. We cannot assure you that the agreements governing the current and future indebtedness of our subsidiaries will permit our subsidiaries to provide us with sufficient dividends, distributions or loans to fund payments on the notes when due. Furthermore, certain of our subsidiaries and affiliates are already subject to project financing. Such entities will not guarantee our obligations on the notes. The debt agreements of these subsidiaries and project affiliates generally restrict their ability to pay dividends, make distributions or otherwise transfer funds to us.

We may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes.

        Upon the occurrence of certain specific kinds of change of control events, we will be required to offer to repurchase all outstanding notes at 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase. However, it is possible that we will not have sufficient funds at the time of a change of control to make the required repurchase of notes and/or restrictions in our Senior Credit Facility or other senior indebtedness will not allow such repurchases. In addition,

11

Table of Contents

certain important corporate events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a "Change of Control" under the indenture. See "Description of the Notes—Repurchase at the Option of Holders."

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors.

        Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee can be voided, or claims in respect of a guarantee can be subordinated to all other debts of that guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee:

•

received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee; and



•

was insolvent or rendered insolvent by reason of such incurrence; or



•

was engaged in a business or transaction for which the guarantor's remaining assets constituted unreasonably small capital; or



•

intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

        In addition, any payment by that guarantor pursuant to its guarantee can be voided and required to be returned to the guarantor, or to a fund for the benefit of the creditors of the guarantor.

        The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a guarantor will be considered insolvent if:

•

the sum of its debts, including contingent liabilities, are greater than the fair saleable value of all of its assets; or



•

the present fair saleable value of its assets are less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or



•

it cannot pay its debts as they become due.

        On the basis of historical financial information, recent operating history and other factors, we believe that each guarantor, after giving effect to its guarantee of these notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

Your ability to transfer the notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market will develop for the notes.

        The Exchange Notes will be registered under the Securities Act, but will constitute a new issue of securities for which there is no established trading market. We do not intend to have the notes listed on a national securities exchange or included in any automated quotation system.

        The liquidity of any market for the notes will depend upon the number of holders of the notes, our performance, the market for similar securities, the interest in securities dealers making a market in the notes and other factors. Therefore, we cannot assure you that an active market for the notes or

12

---

Table of Contents

exchange notes will develop or, if developed, that it will continue. If an active market does not develop or is not maintained, the price and liquidity of the notes will be adversely affected.

        Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. We cannot assure you that the market, if any, for the notes or Exchange Notes will be free from similar disruptions or that any such disruptions may not adversely affect the prices at which you may sell your notes. In addition, subsequent to their initial issuance, the notes or exchange notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our performance and other factors.

        We offered the Old Notes in reliance upon an exemption from registration under the Securities Act and applicable state securities laws. Therefore, the Old Notes may be transferred or resold only in a transaction registered under or exempt from the Securities Act and applicable state securities laws. We are conducting the exchange offer pursuant to an effective registration statement, whereby we are offering to exchange the Old Notes for nearly identical notes that you will be able to trade without registration under the Securities Act provided you are not one of our affiliates. We cannot assure you that this exchange offer will be conducted in a timely fashion. Moreover, we cannot assure you that an active or liquid trading market for the Exchange Notes will develop. See "Exchange Offer."

Risks related to the exchange offer

Holders of Old Notes who fail to exchange their Old Notes in the exchange offer will continue to be subject to restrictions on transfer.

        If you do not exchange your Old Notes for Exchange Notes in the exchange offer, you will continue to be subject to the restrictions on transfer applicable to the Old Notes. The restrictions on transfer of your Old Notes arise because we issued the Old Notes under exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws. In general, you may only offer or sell the Old Notes if they are registered under the Securities Act and applicable state securities laws, or offered and sold under an exemption from these requirements. We do not plan to register the Old Notes under the Securities Act. For further information regarding the consequences of tendering your Old Notes in the exchange offer, see the discussion under the caption "Exchange Offer—Consequences of failure to exchange."

You must comply with the exchange offer procedures to receive Exchange Notes.

        Delivery of Exchange Notes in exchange for Old Notes tendered and accepted for exchange pursuant to the exchange offer will be made only after timely receipt by the exchange agent of the following:

•

certificates for outstanding notes or a book-entry confirmation of a book-entry transfer of outstanding notes into the exchange agent's account at DTC, as depository, including an agent's message, as defined in this prospectus, if the tendering holder does not deliver a letter of transmittal;



•

a complete and signed letter of transmittal, or facsimile copy, with any required signature guarantees, or, in the case of a book-entry transfer, an agent's message in place of the letter of transmittal; and



•

any other documents required by the letter of transmittal.

        Therefore, holders of Old Notes who would like to tender Old Notes in exchange for Exchange Notes should allow enough time for the necessary documents to be timely received by the exchange agent. We are not required to notify you of defects or irregularities in tenders of Old Notes for

13

Table of Contents

exchange. Exchange Notes that are not tendered or that are tendered but we do not accept for exchange will, following consummation of the exchange offer, continue to be subject to the existing transfer restrictions under the Securities Act and, upon consummation of the exchange offer, certain registration and other rights under the Registration Rights Agreement will terminate. See "Exchange Offer—Procedures for tendering Old Notes through brokers and banks" and "Exchange Offer—Consequences of failure to exchange."

Some holders who exchange their Old Notes may be deemed to be underwriters, and these holders will be required to comply with the registration and prospectus delivery requirements in connection with any resale transaction.

        If you exchange your Old Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes, you may be deemed to have received restricted securities and, if so will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

An active trading market may not develop for the Exchange Notes.

        The Exchange Notes have no established trading market and will not be listed on any securities exchange. The initial purchasers are not obligated to make a market in the Exchange Notes. The liquidity of any market for the exchange notes will depend upon various factors, including:

•

the number of holders of the exchange notes;



•

the interest of securities dealers in making a market for the Exchange Notes;



•

the overall market for high yield securities;



•

our financial performance or prospects; and



•

the prospects for companies in our industry generally.

        Accordingly, we cannot assure you that a market or liquidity will develop for the Exchange Notes.

EXCHANGE OFFER

Purpose of the exchange offer

        The exchange offer is designed to provide holders of Old Notes with an opportunity to acquire Exchange Notes which, unlike the Old Notes, will be freely transferable at all times, subject to any restrictions on transfer imposed by state "blue sky" laws and provided that the holder is not our affiliate within the meaning of the Securities Act and represents that the Exchange Notes are being acquired in the ordinary course of the holder's business and the holder is not engaged in, and does not intend to engage in, a distribution of the Exchange Notes.

        The Old Notes were originally issued and sold on December 7, 2017, to the initial purchasers, pursuant to the purchase agreement dated November 30, 2017. The Old Notes were issued and sold in a transaction not registered under the Securities Act in reliance upon the exemption provided by Section 4(2) of the Securities Act. The concurrent resale of the Old Notes by the initial purchasers to investors was done in reliance upon the exemptions provided by Rule 144A and Regulation S promulgated under the Securities Act. The Old Notes may not be reoffered, resold or transferred other than (i) to us or our subsidiaries, (ii) to a qualified institutional buyer in compliance with Rule 144A promulgated under the Securities Act, (iii) outside the U.S. to a non-U.S. person in a transaction complying with Rule 903 or Rule 904 of Regulation S under the Securities Act, (iv) pursuant to the exemption from registration provided by Rule 144 promulgated under the Securities Act (if available), (v) in accordance with another exemption from the registration requirements of the Securities Act or (vi) pursuant to an effective registration statement under the Securities Act.

        In connection with the original issuance and sale of the Old Notes, we entered into the Registration Rights Agreement, pursuant to which we agreed to file with the SEC a registration statement covering the exchange by us of the Exchange Notes for the Old Notes, pursuant to the exchange offer. The Registration Rights Agreement provides that we will file with the SEC an exchange offer registration statement on an appropriate form under the Securities Act and offer to holders of Old Notes who are able to make certain representations the opportunity to exchange their Old Notes for Exchange Notes. Under some circumstances, holders of the Old Notes, including holders who are not permitted to participate in the exchange offer, may require us to file, and to cause to become effective, a shelf registration statement covering resales of Old Notes to these holders.

        Under existing interpretations by the Staff of the SEC as set forth in no-action letters issued to third parties in other transactions, the Exchange Notes would, in general, be freely transferable after the exchange offer without further registration under the Securities Act; provided, however, that in the case of broker-dealers participating in the exchange offer, a prospectus meeting the requirements of the Securities Act must be delivered by such broker-dealers in connection with resales of the Exchange Notes. We have agreed to furnish a prospectus meeting the requirements of the Securities Act to any such broker-dealer for use in connection with any resale of any Exchange Notes acquired in the exchange offer. A broker-dealer that delivers such a prospectus to purchasers in connection with such resales will be subject to certain of the civil liability provisions under the Securities Act and will be bound by the provisions of the Registration Rights Agreement (including certain indemnification rights and obligations).

        We do not intend to seek our own interpretation regarding the exchange offer, and we cannot assure you that the Staff of the SEC would make a similar determination with respect to the Exchange Notes as it has in other interpretations to third parties.

Terms of the exchange offer; period for tendering outstanding Old Notes

        Upon the terms and subject to the conditions set forth in this prospectus, we will accept any and all Old Notes that were acquired pursuant to Rule 144A or Regulation S validly tendered and not

withdrawn prior to 12:00 midnight, New York City time, on the expiration date of the exchange offer. We will issue $1,000 principal amount of Exchange Notes in exchange for each $1,000 principal amount of Old Notes accepted in the exchange offer. We will issue the Exchange Notes promptly after expiration of the exchange offer.

        Holders may tender some or all of their Old Notes pursuant to the exchange offer. However, Old Notes may be tendered only in minimum principal amounts of $2,000 and integral multiples of $1,000 in excess thereof.

        The form and terms of the Exchange Notes are the same as the form and terms of the outstanding Old Notes except that:

•

the Exchange Notes will be registered under the Securities Act and will not have legends restricting their transfer; and



•

the Exchange Notes will not contain the registration rights and liquidated damages provisions contained in the outstanding Old Notes.

        The Exchange Notes will evidence the same debt as the Old Notes and will be entitled to the benefits of the indenture governing the Old Notes.

        We intend to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act, and the rules and regulations of the SEC.

        We will be deemed to have accepted validly tendered Old Notes when, as and if we have given oral (promptly confirmed in writing) or written notice of our acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purpose of receiving the Exchange Notes from us.

        If any tendered Old Notes are not accepted for exchange because of an invalid tender or the occurrence of certain specified events set forth in this prospectus, the certificates for any unaccepted Old Notes will be promptly returned, without expense, to the tendering holder.

        Holders who tender Old Notes in the exchange offer will not be required to pay brokerage commissions or fees or transfer taxes with respect to the exchange of Old Notes pursuant to the exchange offer. We will pay all charges and expenses, other than transfer taxes in certain circumstances, in connection with the exchange offer. See "—Fees and expenses" and "—Transfer taxes" below.

        The exchange offer will remain open for at least 20 full business days. The term "expiration date" will mean 12:00 midnight, New York City time, on October 30, 2018, unless we extend the exchange offer, in which case the term "expiration date" will mean the latest date and time to which the exchange offer is extended.

        To extend the exchange offer, prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date, we will:

•

notify the exchange agent of any extension by oral notice (promptly confirmed in writing) or written notice, and



•

mail to the registered holders an announcement of any extension, and issue a notice by press release or other public announcement before such expiration date.

        We reserve the right:

•

if any of the conditions below under the heading "Conditions to the Exchange Offer" shall have not been satisfied, to delay accepting any Old Notes in connection with the extension of the exchange offer, to extend the exchange offer, or to terminate the exchange offer, or

•

to amend the terms of the exchange offer in any manner, provided however, that if we amend the exchange offer to make a material change, including the waiver of a material condition, we will extend the exchange offer, if necessary, to keep the exchange offer open for at least five business days after such amendment or waiver; provided further, that if we amend the exchange offer to change the percentage of Notes being exchanged or the consideration being offered, we will extend the exchange offer, if necessary, to keep the exchange offer open for at least ten business days after such amendment or waiver.

        Any delay in acceptance, extension, termination or amendment will be followed promptly by oral or written notice by us to the registered holders.

Required representations

        To participate in the exchange offer, we require that you represent to us, among other things, that:

•

you or any other person acquiring Exchange Notes in exchange for your Old Notes in the exchange offer is acquiring them in the ordinary course of business;



•

neither you nor any other person acquiring Exchange Notes for your Old Notes in the exchange offer is engaging in or intends to engage in (or entered into any arrangement or understanding with any person to participate in) a distribution of the Exchange Notes within the meaning of the federal securities laws;



•

neither you nor any other person acquiring Exchange Notes for your Old Notes in the exchange offer is our "affiliate" as defined under Rule 405 of the Securities Act;

•

the Old Notes to be exchanged for Exchange Notes were acquired as a result of market-making activities or other trading activities;

•

you are not acting on behalf of any person or entity that could not truthfully make those representations.

        BY TENDERING YOUR OLD NOTES YOU ARE DEEMED TO HAVE MADE THESE REPRESENTATIONS.

        Broker-dealers who cannot make the representations above cannot use this exchange offer prospectus in connection with resales of the Exchange Notes issued in the exchange offer.

Resale of Exchange Notes

        Based on interpretations of the SEC Staff set forth in no-action letters issued to unrelated third parties, we believe that Exchange Notes issued in the exchange offer in exchange for Old Notes may be

19

Table of Contents

offered for resale, resold and otherwise transferred by any Exchange Note holder without compliance with the registration and prospectus delivery provisions of the Securities Act, if:

•

such holder is not an "affiliate" of ours within the meaning of Rule 405 under the Securities Act;



•

such Exchange Notes are acquired in the ordinary course of the holder's business; and



•

the holder does not intend to participate in the distribution of such Exchange Notes.

        Any holder who tenders in the exchange offer with the intention of participating in any manner in a distribution of the Exchange Notes, who is an affiliate of ours or who is a broker or dealer who acquired Old Notes directly from us:

•

cannot rely on the position of the Staff of the SEC set forth in "Exxon Capital Holdings Corporation" or similar interpretive letters; and



•

must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

        If, as stated above, a holder cannot rely on the position of the Staff of the SEC set forth in "Exxon Capital Holdings Corporation" or similar interpretive letters, any effective registration statement used in connection with a secondary resale transaction must contain the selling security holder information required by Item 507 of Regulation S-K under the Securities Act.

        With regard to broker-dealers, only broker-dealers that acquired the Old Notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the Exchange Notes. See "Plan of Distribution."

        This prospectus may be used for an offer to resell, for the resale or for other retransfer of Exchange Notes only as specifically set forth in this prospectus.

        Please read the section captioned "Plan of Distribution" for more details regarding these procedures for the transfer of Exchange Notes.

Procedures for tendering Old Notes through brokers and banks

        Since the Old Notes are represented by global book-entry notes, DTC, as depositary, or its nominee is treated as the registered holder of the Old Notes and will be the only entity that can tender your Old Notes for Exchange Notes. Therefore, to tender Old Notes subject to this exchange offer and to obtain Exchange Notes, you must instruct the institution where you keep your Old Notes to tender your Old Notes on your behalf so that they are received on or prior to the expiration of this exchange offer.

        YOU SHOULD CONSULT YOUR ACCOUNT REPRESENTATIVE AT THE BROKER OR BANK WHERE YOU KEEP YOUR OLD NOTES TO DETERMINE THE PREFERRED PROCEDURE.

        IF YOU WISH TO ACCEPT THIS EXCHANGE OFFER, PLEASE INSTRUCT YOUR BROKER OR ACCOUNT REPRESENTATIVE IN TIME FOR YOUR OLD NOTES TO BE TENDERED BEFORE THE 12:00 MIDNIGHT (NEW YORK CITY TIME) DEADLINE ON OCTOBER 30, 2018.

        When you tender your outstanding Old Notes and we accept them, the tender will be a binding agreement between you and us as described in this prospectus.

20

---

Table of Contents

        The method of delivery of outstanding Old Notes and all other required documents to the exchange agent is at your election and risk.

        We will decide all questions about the validity, form, eligibility, acceptance and withdrawal of tendered Old Notes. We reserve the absolute right to:

•

reject any and all tenders of any particular Old Note not properly tendered;



•

refuse to accept any Old Note if, in our reasonable judgment or the judgment of our counsel, the acceptance would be unlawful; and



•

waive any defects or irregularities or conditions of the exchange offer as to any particular Old Notes before the expiration of the offer.

        Our interpretation of the terms and conditions of the exchange offer will be final and binding on all parties. You must cure any defects or irregularities in connection with tenders of Old Notes as we will reasonably determine. Neither us, the exchange agent nor any other person will incur any liability for failure to notify you of any defect or irregularity with respect to your tender of Old Notes. If we waive any terms or conditions with respect to a noteholder, we will extend the same waiver to all noteholders with respect to that term or condition being waived.

Procedures for brokers and custodian banks; DTC ATOP accounts

        In order to accept this exchange offer on behalf of a holder of Old Notes you must submit or cause your DTC participant to submit an Agent's Message as described below.

        The exchange agent, on our behalf, will seek to establish separate Automated Tender Offer Program ("ATOP") accounts with respect to each series of outstanding Old Notes at DTC promptly after the delivery of this prospectus. Any financial institution that is a DTC participant, including your broker or bank, may make book-entry tender of outstanding Old Notes by causing the book- entry transfer of such Old Notes into the relevant ATOP account in accordance with DTC's procedures for such transfers. Although delivery of the Old Notes may be effected through book-entry transfer into the exchange agent's account at DTC, unless an Agent's Message is received by the exchange agent in compliance with ATOP procedures, an appropriate letter of transmittal properly completed and duly executed with any required signature guarantee and all other required documents must in each case be transmitted to and received or confirmed by the exchange agent at its address set forth in this prospectus prior to 12:00 midnight, New York City time on to the expiration date. The confirmation of a book entry transfer into the ATOP account as described above is referred to herein as a "Book-Entry Confirmation."

        The term "Agent's Message" means a message transmitted by the DTC participants to DTC, and thereafter transmitted by DTC to the exchange agent, forming a part of the Book-Entry Confirmation which states that DTC has received an express acknowledgment from the participant in DTC described in such Agent's Message stating that such participant has received the letter of transmittal and this prospectus and agrees to be bound by the terms of the letter of transmittal and the exchange offer set forth in this prospectus and that we may enforce such agreement against the participant.

        Each Agent's Message must include the following information:

•

Name of the beneficial owner tendering such Old Notes;



•

Account number of the beneficial owner tendering such Old Notes;



•

Principal amount of Old Notes tendered by such beneficial owner; and



•

A confirmation that the beneficial holder of the Old Notes tendered has made the representations for our benefit set forth under "—Deemed representations."

        BY SENDING AN AGENT'S MESSAGE THE DTC PARTICIPANT IS DEEMED TO HAVE CERTIFIED THAT THE BENEFICIAL HOLDER FOR WHOM NOTES ARE BEING TENDERED HAS BEEN PROVIDED WITH A COPY OF THIS PROSPECTUS.

        The delivery of Old Notes through DTC, delivery of a letter of transmittal, and any transmission of an Agent's Message through ATOP, is at the election and risk of the person tendering Old Notes. We will ask the exchange agent to instruct DTC to promptly return those Old Notes, if any, that were tendered through ATOP but were not accepted by us, to the DTC participant that tendered such Old Notes on behalf of holders of the Old Notes.

        THE AGENT'S MESSAGE MUST BE TRANSMITTED TO THE EXCHANGE AGENT ON OR BEFORE 12:00 MIDNIGHT, NEW YORK CITY TIME, ON THE EXPIRATION DATE.

Acceptance of outstanding Old Notes for exchange; Delivery of Exchange Notes

        We will accept validly tendered Old Notes when the conditions to the exchange offer have been satisfied or we have waived them. We will have accepted your validly tendered Old Notes when we have given oral (promptly confirmed in writing) or written notice to the exchange agent. The exchange agent will act as agent for the tendering holders for the purpose of receiving the Exchange Notes from us. We will issue the Exchange Notes promptly after termination of the exchange offer. If we do not accept any tendered Old Notes for exchange by book-entry transfer because of an invalid tender or other valid reason, we will credit the Old Notes to an account maintained with DTC promptly after the exchange offer terminates or expires.

Guaranteed delivery procedures

        If you desire to tender Old Notes pursuant to the exchange offer and (1) time will not permit your letter of transmittal and all other required documents to reach the exchange agent on or prior to the expiration date, or (2) the procedures for book-entry transfer (including delivery of an agent's message) cannot be completed on or prior to the expiration date, you may nevertheless tender such Old Notes with the effect that such tender will be deemed to have been received on or prior to the expiration date if all the following conditions are satisfied:

•

you must effect your tender through an "eligible guarantor institution";



•

a properly completed and duly executed notice of guaranteed delivery, substantially in the form provided by us herewith, or an agent's message with respect to guaranteed delivery that is accepted by us, is received by the exchange agent on or prior to the expiration date as provided below; and



•

a book-entry confirmation of the transfer of such notes into the exchange agent account at DTC as described above, together with a letter of transmittal (or a manually signed facsimile of the letter of transmittal) properly completed and duly executed, with any signature guarantees and any other documents required by the letter of transmittal or a properly transmitted agent's message, are received by the exchange agent within three business days after the date of execution of the notice of guaranteed delivery.

        The notice of guaranteed delivery may be sent by hand delivery, facsimile transmission or mail to the exchange agent and must include a guarantee by an eligible guarantor institution in the form set forth in the notice of guaranteed delivery.

Withdrawal rights

        You may withdraw your tender of Old Notes at any time before 12:00 midnight, New York City time, on the expiration date.

22

Table of Contents

        For a withdrawal to be effective, you should contact your bank or broker where your Old Notes are held and have them send a telegram, telex, letter or facsimile transmission notice of withdrawal (or in the case of Old Notes transferred by book-entry transfer, an electronic ATOP transmission notice of withdrawal) so that it is received by the exchange agent before 12:00 midnight, New York City time, on the expiration date. Such notice of withdrawal must:

•

specify the name of the person that tendered the Old Notes to be withdrawn;



•

identify the Old Notes to be withdrawn, including the CUSIP number and principal amount at maturity of the Old Notes; specify the name and number of an account at the DTC to which your withdrawn Old Notes can be credited;



•

if applicable, be signed by the holder in the same manner as the original signature on the letter of transmittal by which such Old Notes were tendered, with any required signature guarantees, or be accompanied by documents of transfer sufficient to have the trustee with respect to the Old Notes register the transfer of such Old Notes into the name of the person withdrawing the tender; and



•

specify the name in which any such notes are to be registered, if different from that of the registered holder.

        We will decide all questions as to the validity, form and eligibility of the notices and our determination will be final and binding on all parties. Any tendered Old Notes that you withdraw will not be considered to have been validly tendered. We will promptly return any outstanding Old Notes that have been tendered but not exchanged, or credit them to the DTC account. You may re-tender properly withdrawn Old Notes by following one of the procedures described above before the expiration date.

Conditions to the exchange offer

        Notwithstanding any other provision of the exchange offer, or any extension of the exchange offer, we will not be required to accept for exchange, or to issue Exchange Notes in exchange for, any outstanding Old Notes and may terminate the exchange offer (whether or not any Old Notes have been accepted for exchange) or amend the exchange offer, if any of the following conditions has occurred or exists or has not been satisfied, or has not been waived by us, prior to the expiration date:

•

any statute, rule, regulation, order or injunction has been sought, proposed, introduced, enacted, promulgated or deemed applicable to the exchange offer or any of the transactions contemplated by the exchange offer by any governmental authority, domestic or foreign; or



•

any action has been taken, proposed or threatened, by any governmental authority, domestic or foreign, that would, directly or indirectly, result in any of the consequences referred to in the clauses above or would result in the holders of Exchange Notes having obligations with respect to resales and transfers of Exchange Notes which are greater than those described in the interpretation of the SEC referred to above;

•

any of the following has occurred:

•

there shall occur a change in the current interpretation by the Staff of the SEC which permits the Exchange Notes issued pursuant to the exchange offer in exchange for Old Notes to be offered for resale, resold and otherwise transferred by holders thereof (other than broker-dealers and any such holder which is our affiliate within the meaning of Rule 405 promulgated under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Exchange Notes are acquired in the ordinary course of such holders' business and such holders have no arrangement or understanding with any person to participate in the distribution of such Exchange Notes;



•

any law, statute, rule or regulation shall have been adopted or enacted which would impair our ability to proceed with the exchange offer;



•

a stop order shall have been issued by the SEC or any state securities authority suspending the effectiveness of the registration statement, or proceedings shall have been initiated or, to our knowledge, threatened for that purpose, or any governmental approval necessary for the consummation of the exchange offer as contemplated hereby has not been obtained; or



•

we have received an opinion of counsel experienced in such matters to the effect that there exists any actual or threatened legal impediment (including a default or prospective default under an agreement, indenture or other instrument or obligation to which we are a party or by which we are bound) to the consummation of the transactions contemplated by the exchange offer.

        If any of the foregoing events or conditions has occurred or exists or has not been satisfied, we may, subject to applicable law, terminate the exchange offer (whether or not any Old Notes have been accepted for exchange) or may waive any such condition or otherwise amend the terms of the exchange offer in any respect. If such waiver or amendment constitutes a material change to the exchange offer, we will promptly disclose such waiver or amendment by means of a prospectus supplement that will be distributed to the registered holders of the Old Notes and will extend the exchange offer to the extent required by Rule 14e-1 promulgated under the Exchange Act.

Table of Contents

        These conditions are for our sole benefit and we may assert them regardless of the circumstances giving rise to any of these conditions, or we may waive them, in whole or in part, provided that we will not waive any condition with respect to an individual holder of Old Notes unless we waive that condition for all such holders. Any reasonable determination made by us concerning an event, development or circumstance described or referred to above will be final and binding on all parties. Our failure at any time to exercise any of the foregoing rights will not be a waiver of our rights and each such right will be deemed an ongoing right which may be asserted at any time before the expiration of the exchange offer.

Exchange agent

        We have appointed Delaware Trust Company as the exchange agent for the exchange offer. You should direct questions, requests for assistance, and requests for additional copies of this prospectus and the letter of transmittal that may accompany this prospectus to the exchange agent addressed as follows:

DELAWARE TRUST COMPANY, EXCHANGE AGENT

Delivery to an address other than set forth above will not constitute a valid delivery.

Fees and expenses

        The principal solicitation is being made through DTC by Delaware Trust Company, as exchange agent on our behalf. We will pay the exchange agent customary fees for its services, reimburse the exchange agent for its reasonable costs and expenses (including reasonable fees, costs and expenses of its counsel) incurred in connection with the provisions of these services and pay other registration expenses, including registration and filing fees, fees and expenses of compliance with federal securities and state blue sky securities laws, printing expenses, messenger and delivery services and telephone, fees and disbursements to our counsel, application and filing fees and any fees and disbursements to our independent certified public accountants. We will not make any payment to brokers, dealers, or others soliciting acceptances of the exchange offer except for reimbursement of mailing expenses.

        Additional solicitations may be made by telephone, facsimile or in person by our and our affiliates' officers employees and by persons so engaged by the exchange agent.

Accounting treatment

        The Exchange Notes will be recorded at the same carrying value as the existing Old Notes, as reflected in our accounting records on the date of exchange. Accordingly, we will recognize no gain or loss for accounting purposes. The expenses of the exchange offer will be capitalized and expensed over the term of the Exchange Notes.

Transfer taxes

        If you tender outstanding Old Notes for exchange you will not be obligated to pay any transfer taxes. However, if you instruct us to register Exchange Notes in the name of, or request that your Old

25

---

Table of Contents

Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder, you will be responsible for paying any transfer tax owed.

        YOU MAY SUFFER ADVERSE CONSEQUENCES IF YOU FAIL TO EXCHANGE OUTSTANDING OLD NOTES.

        If you do not tender your outstanding Old Notes, you will not have any further registration rights, except for the rights described in the Registration Rights Agreement and described above, and your Old Notes will continue to be subject to the provisions of the respective indenture governing the Old Notes regarding transfer and exchange of the Old Notes and the restrictions on transfer of the Old Notes imposed by the Securities Act and states securities law when we complete the exchange offer. These transfer restrictions are required because the Old Notes were issued under an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. Accordingly, if you do not tender your Old Notes in the exchange offer, your ability to sell your Old Notes could be adversely affected. Once we have completed the exchange offer, holders who have not tendered notes will not continue to be entitled to any increase in interest rate that the indenture governing the Old Note provides for if we do not complete the exchange offer.

Consequences of failure to exchange

        The Old Notes that are not exchanged for Exchange Notes pursuant to the exchange offer will remain restricted securities. Accordingly, the Old Notes may be resold only:

•

to us upon redemption thereof or otherwise;



•

so long as the outstanding securities are eligible for resale pursuant to Rule 144A, to a person inside the U.S. who is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act in a transaction meeting the requirements of Rule 144A, in accordance with Rule 144 under the Securities Act, or pursuant to another exemption from the registration requirements of the Securities Act, which other exemption is based upon an opinion of counsel reasonably acceptable to us;



•

outside the U.S. to a foreign person in a transaction meeting the requirements of Rule 904 under the Securities Act; or



•

pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any state of the U.S.

        Under certain limited circumstances, the Registration Rights Agreement requires that we file a shelf registration statement if:

•

we are not permitted by applicable law or SEC policy to file a registration statement covering the exchange offer or to consummate the exchange offer; or



•

any holder of the Old Notes notifies the Issuer prior to the 20th calendar day following the consummation of the exchange offer that:



•

it is prohibited by law or SEC policy from participating in the exchange offer;



•

it may not resell the Exchange Notes acquired by it in the exchange offer to the public without delivering a prospectus and this prospectus is not appropriate or available for such resales; or



•

it is a broker-dealer and owns Old Notes acquired directly from the Issuer or an affiliate of the Issuer.

26

Table of Contents

        We will also register the Exchange Notes under the securities laws of jurisdictions that holders may request before offering or selling notes in a public offering. We do not intend to register Exchange Notes in any jurisdiction unless a holder requests that we do so.

        Old Notes may be subject to restrictions on transfer until:

•

a person other than a broker-dealer has exchanged the Old Notes in the exchange offer;



•

a broker-dealer has exchanged the Old Notes in the exchange offer and sells them to a purchaser that receives a prospectus from the broker, dealer on or before the sale;



•

the Old Notes are sold under an effective shelf registration statement that we have filed; or



•

the Old Notes are sold to the public under Rule 144 of the Securities Act.

USE OF PROCEEDS

        This exchange offer is intended to satisfy our obligations under the Registration Rights Agreement. We will not receive any cash proceeds, or otherwise, from the issuance of the Exchange Notes. The Old Notes properly tendered and exchanged for Exchange Notes will be retired and cancelled. Accordingly, no additional debt will result from the exchange. We have agreed to bear the expense of the exchange offer.

RATIO OF EARNINGS TO FIXED CHARGES

        The ratio of earnings to fixed charges for the periods indicated is stated below. For this purpose, "earnings" include pre-tax income (loss) before adjustments for noncontrolling interest in our consolidated subsidiaries and income or loss from equity investees, plus fixed charges and distributed income of equity investees, reduced by interest capitalized. "Fixed charges" include interest, whether expensed or capitalized, amortization of debt expense and the portion of rental expense that is representative of the interest factor in these rentals.

DESCRIPTION OF THE NOTES

In this description, "NRG" refers only to NRG Energy, Inc. and not to any of its subsidiaries.

        NRG issued the Old Notes under an indenture among NRG, the Guarantors named therein and Delaware Trust Company, as trustee (the "base indenture"), as supplemented by a supplemental indenture (the "supplemental indenture" and, together with the base indenture, the "indenture"). The terms of the Exchange Notes offered in exchange for the Old Notes will be substantially identical to the terms of the Old Notes, except that the Exchange Notes are registered under the Securities Act, and the transfer restrictions, registration rights and related additional interest terms applicable to the Old Notes (as described under "Exchange Offer—Purpose of the exchange offer") will not apply to the Exchange Notes. As a result, we refer to the Exchange Notes and the Old Notes collectively as the "notes" for purposes of the following summary.

        The statements under this caption relating to the indenture and the notes are summaries and are not a complete description thereof, and where reference is made to particular provisions, such provisions, including the definitions of certain terms, are qualified in their entirety by reference to all of the provisions of the indenture and the notes and those terms made part of the indenture by the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The definitions of certain capitalized terms used in the following summary are set forth under the caption "—Certain definitions." Certain defined terms used in this description but not defined below under "—Certain definitions" have the meanings assigned to them in the indenture and the registration rights agreement. Copies of the indenture are available upon request from the Company. We urge you to read these documents carefully because they, and not the following description, govern your rights as a holder.

        The registered holder of a note is treated as the owner of it for all purposes. Only registered holders of notes have rights under the indenture.

Brief Description of the Notes

        The notes:

•

will be general unsecured obligations of NRG;



•

will be pari passu in right of payment with all existing and future unsecured senior Indebtedness of NRG;



•

will be senior in right of payment to any future subordinated Indebtedness of NRG; and



•

will be unconditionally guaranteed on a joint and several basis by the Guarantors.

        However, the notes will be effectively subordinated to all borrowings under the Credit Agreement, which is secured by substantially all of the assets of NRG and the Guarantors, and any other secured Indebtedness (including any Hedging Obligations secured by liens on assets of NRG or its subsidiaries) of NRG or the Guarantors, in each case to the extent of the value of the assets that secure the Credit Agreement or other secured Indebtedness. See "Risk Factors—Risks Related to the Notes—In the event of a bankruptcy or insolvency, holders of our secured indebtedness and other secured obligations will have a prior secured claim to any collateral securing such indebtedness or other obligations."

The Subsidiary Guarantees

        The notes will initially be guaranteed by each Subsidiary of NRG that is a guarantor of any obligations under NRG's Credit Agreement. Each Subsidiary Guarantee of the notes:

•

will be a general unsecured obligation of the Guarantor;

29

---

Table of Contents

•

will be pari passu in right of payment with all unsecured senior Indebtedness of that Guarantor; and



•

will be senior in right of payment to any future subordinated Indebtedness of that Guarantor.

        However, each Guarantor's guarantee of the notes will be effectively subordinated to such Guarantor's guarantee under the Credit Agreement and any other secured Indebtedness of such Guarantor (including any Hedging Obligations secured by liens on assets of such Guarantor), in each case to the extent of the value of the assets of such Guarantor that secure the Credit Agreement or other secured Indebtedness.

        The operations of NRG are largely conducted through its subsidiaries and, therefore, NRG depends on the cash flow of its subsidiaries to meet its obligations, including its obligations under the notes. Not all of NRG's subsidiaries will guarantee the notes. The notes will be effectively subordinated in right of payment to all Indebtedness and other liabilities and commitments (including trade payables, lease obligations, indebtedness for borrowed money and Hedging Obligations) of these non-guarantor subsidiaries. Any right of NRG to receive assets of any of its subsidiaries upon the subsidiary's liquidation or reorganization (and the consequent right of the holders of notes to participate in those assets) will be effectively subordinated to the claims of that subsidiary's creditors, except to the extent that NRG is itself recognized as a creditor of the subsidiary, in which case its claims would still be subordinated in right of payment to any security in the assets of the subsidiary and any indebtedness of the subsidiary senior to that held by NRG. The Guarantors accounted for approximately 77% and 68% of NRG's revenues from wholly-owned operations for the six months ended June 30, 2018 and the year ended December 31, 2017, respectively. The Guarantors held approximately 39% of NRG's consolidated assets as of June 30, 2018. As of June 30, 2018, NRG's non-guarantor subsidiaries had approximately $8 billion in aggregate principal amount of non-current liabilities and outstanding trade payables of approximately $230 million.

Principal, Maturity and Interest

        NRG will issue notes in this offering having an aggregate principal amount of $870 million. NRG may issue additional notes of the same series under the indenture from time to time after this offering; provided that any such additional notes that are not fungible with the notes we are currently offering for U.S. federal income tax purposes will be issued with a different CUSIP Number than the CUSIP Number issued with respect to the notes we are currently offering. Any issuance of additional notes is subject to the covenants in the indenture. The notes offered hereby and any additional notes of the same series subsequently issued under the indenture will be treated as a single class for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. In addition, we may issue an unlimited amount of debt securities in one or more additional series under the indenture, subject to the covenants in the indenture. The notes will not be treated as a single class with any such other debt securities of different series for any purpose under the indenture.

        NRG will issue notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will mature on January 15, 2028.

        Interest will accrue at the rate of 5.75% per annum, and will be payable semi-annually in arrears on January 15 and July 15 of each year, commencing on July 15, 2018. NRG will make each interest payment to the holders of record on the immediately preceding January 1 and July 1.

Methods of Receiving Payments on the Notes

        If a holder of notes has given wire transfer instructions to NRG, NRG will pay or cause to be paid all principal, interest and premium on that holder's notes in accordance with those instructions. All other payments on notes will be made at the office or agency of the paying agent and registrar within

the City and State of New York unless NRG elects to make interest payments by check mailed to the holders of the notes at their addresses set forth in the register of holders.

Paying Agent and Registrar for the Notes

        The trustee will initially act as paying agent and registrar. NRG may change the paying agent or registrar without prior notice to the holders of the notes, and NRG or any of its Subsidiaries may act as paying agent or registrar.

Transfer and Exchange

        A holder may transfer or exchange notes in accordance with the provisions of the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders of the notes will be required to pay all taxes due on transfer. NRG is not required to transfer or exchange any note selected for redemption. Also, NRG is not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

Subsidiary Guarantees

        NRG's payment obligations under the notes will be guaranteed on an unconditional basis by each of the Guarantors. These Subsidiary Guarantees will be joint and several obligations of the Guarantors. The obligations of each Guarantor under its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law. See "Risk Factors—Risks Related to the Notes—Federal and state statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors."

        The Subsidiary Guarantee of a Guarantor of the notes will be released automatically:

        (1)   in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) NRG or a Subsidiary of NRG;

        (2)   in connection with any sale or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) NRG or a Subsidiary of NRG, if following such sale or other disposition, that Guarantor is not a direct or indirect Subsidiary of NRG;

        (3)   upon defeasance or satisfaction and discharge of the notes as provided below under the captions "—Legal Defeasance and Covenant Defeasance" and "—Satisfaction and Discharge";

        (4)   upon a dissolution of a Guarantor that is permitted under the indenture; or

        (5)   otherwise with respect to the Guarantee of any Guarantor:

        (a)   upon the prior consent of holders of at least a majority in aggregate principal amount of the notes then outstanding;

        (b)   if NRG has Indebtedness outstanding under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time) at that time, upon the consent of the requisite lenders under the Credit Agreement to the release of such Guarantor's Guarantee of all Obligations under the Credit Agreement, or, if there is no Indebtedness of NRG outstanding under the Credit Agreement at that time, upon the requisite consent of the holders of all other Indebtedness for borrowed money of NRG that is guaranteed by such Guarantor at that time outstanding to the release of such Guarantor's

31

Table of Contents

Guarantee of all Obligations with respect to all other Indebtedness for borrowed money that is guaranteed by such Guarantor at that time outstanding; or

        (c)   if NRG has Indebtedness outstanding under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time) at that time, upon the release of such Guarantor's Guarantee of all Obligations of NRG under the Credit Agreement, or, if there is no Indebtedness of NRG outstanding under the Credit Agreement at that time, upon the release of such Guarantor's Guarantee of all Obligations with respect to all other Indebtedness for borrowed money of NRG at that time outstanding.

Optional Redemption

        At any time prior to January 15, 2021, NRG may on any one or more occasions redeem up to 35% of the aggregate principal amount of the notes, upon not less than 15 nor more than 60 days' prior notice, at a redemption price equal to 105.750% of the principal amount of the notes redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount equal to the net cash proceeds of one or more equity offerings, subject to the rights of holders of the notes on the relevant record date to receive interest due on the relevant interest payment date; provided that:

        (1)   at least 65% of the aggregate principal amount of the notes issued in this offering (excluding notes held by NRG and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

        (2)   the redemption occurs within 180 days of the date of the closing of such equity offering.

        At any time prior to January 15, 2023, NRG may on any one or more occasions redeem all or a part of the notes, upon not less than 15 nor more than 60 days' prior notice, at a redemption price equal to 100% of the principal amount of notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the redemption date, subject to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date.

        Except pursuant to the preceding paragraphs, the notes will not be redeemable at NRG's option prior to January 15, 2023.

        On or after January 15, 2023, NRG may on any one or more occasions redeem all or a part of the notes upon not less than 15 nor more than 60 days' prior notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, on the notes redeemed, to the applicable redemption date, if redeemed during the 12-month period beginning on January 15 of the years indicated below, subject to the rights of holders of notes on the relevant record date to receive interest on the relevant interest payment date.

        NRG is not prohibited, however, from acquiring the notes in market transactions by means other than a redemption, whether pursuant to a tender offer or otherwise, assuming such action does not otherwise violate the indenture.

Mandatory Redemption

        NRG will not be required to make mandatory redemption or sinking fund payments with respect to the notes.

Repurchase at the Option of Holders

Change of Control Triggering Event

        If a Change of Control Triggering Event occurs, each holder of notes will have the right to require NRG to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder's notes pursuant to a Change of Control Offer on the terms set forth in the indenture.

        In the Change of Control Offer, NRG will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of the notes, plus accrued and unpaid interest, if any, on the notes to the date of purchase, subject to the rights of holders of the notes on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control Triggering Event, NRG will mail a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 15 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the indenture and described in such notice. NRG will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, NRG will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indenture by virtue of such compliance.

        On the Change of Control Payment Date, NRG will, to the extent lawful:

        (1)   accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer;

        (2)   deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and

        (3)   deliver or cause to be delivered to the trustee the notes properly accepted together with an officers' certificate stating the aggregate principal amount of notes or portions of notes being purchased by NRG.

        The paying agent will promptly distribute to each holder of notes properly tendered the Change of Control Payment for the notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. NRG will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

        The provisions described above that require NRG to make a Change of Control Offer following a Change of Control Triggering Event will be applicable whether or not any other provisions of the indenture are applicable.

        Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit the holders of the notes to require that NRG repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

        NRG will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by NRG and purchases all notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to the indenture as

33

Table of Contents

described above under the caption "—Optional Redemption," unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, with the obligation to pay and the timing of payment conditioned upon the occurrence of a Change of Control Triggering Event, if a definitive agreement to effect a Change of Control is in place at the time the Change of Control Offer is made.

        If holders of not less than 90.0% in aggregate principal amount of the outstanding notes validly tender and do not withdraw such notes in a Change of Control Offer and NRG, or any third party making a Change of Control Offer in lieu of NRG as described above, purchases all of the notes validly tendered and not withdrawn by such holders, NRG will have the right, upon not less than 15 nor more than 60 days' prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment, plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to the date of redemption.

        The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the properties or assets of NRG and its Subsidiaries taken as a whole. There is a limited body of case law interpreting the phrase "substantially all," and there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require NRG to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of NRG and its Subsidiaries taken as a whole to another Person or group may be uncertain.

Selection and Notice

        If less than all of the notes are to be redeemed at any time, the trustee for the notes will select notes for redemption on a pro rata basis unless otherwise required by law, applicable stock exchange requirements or depositary requirements.

        No notes of $2,000 or less can be redeemed in part. Notices of redemption will be mailed by first class mail at least 15 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture. Any redemption notice may, in NRG's discretion, be subject to the satisfaction of one or more conditions precedent.

        If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption.

Certain Covenants

Liens

        NRG will not, and will not permit any Guarantor, to create or permit to exist any Lien upon any Principal Property owned by NRG or any Guarantor or upon any Equity Interests issued by, or Indebtedness of, any direct or indirect Subsidiary of NRG, to secure any Indebtedness of NRG or any Guarantor without providing for the notes to be equally and ratably secured with (or prior to) any and all such Indebtedness and any other Indebtedness similarly entitled to be equally and ratably secured

34

Table of Contents

for so long as such Indebtedness is so secured; provided, however, that this restriction will not apply to, or prevent the creation or existence of:

        (1)   Liens securing Indebtedness of NRG or any Guarantor under one or more Credit Facilities in an aggregate principal amount, measured as of the date of creation of any such Lien and the date of incurrence of any such Indebtedness, not exceeding the greatest of (a) 30% of Total Assets, (b) $10.0 billion and (c) such amount as would not cause the Secured Leverage Ratio to exceed 3.5 to 1.0;

        (2)   Existing Liens;

        (3)   Liens securing Indebtedness of any Person that (a) is acquired by NRG or any of its Subsidiaries after the date of the indenture, (b) is merged or amalgamated with or into NRG or any of its Subsidiaries after the date of the indenture or (c) becomes consolidated in the financial statements of NRG or any of its Subsidiaries after the date of the indenture in accordance with GAAP; provided, however, that in each case contemplated by this clause (3), such Indebtedness was not incurred in contemplation of such acquisition, merger, amalgamation or consolidation and is only secured by Liens on the Equity Interests and assets of, the Person (and Subsidiaries of the Person) acquired by, or merged or amalgamated with or into, or consolidated in the financial statements of, NRG or any of its Subsidiaries;

        (4)   Liens securing Indebtedness of NRG or any Guarantor incurred to finance (whether prior to or within 365 days after) the acquisition, construction or improvement of assets (whether through the direct purchase of assets or through the purchase of the Equity Interests of any Person owning such assets or through an acquisition of any such Person by merger); provided, however, that such Indebtedness is only secured by Liens on the Equity Interests and assets acquired, constructed or improved in such financing (and related contracts, intangibles, and other assets that are incidental thereto or arise therefrom (including accessions thereto and replacements or proceeds thereof));

        (5)   Liens in favor of NRG or any of its Subsidiaries;

        (6)   Liens securing Hedging Obligations; provided that such agreements were not entered into for speculative purposes (as determined by NRG in its reasonable discretion acting in good faith);

        (7)   Liens relating to current or future escrow arrangements securing Indebtedness of NRG or any Guarantor;

        (8)   Liens to secure Environmental CapEx Debt or Necessary CapEx Debt that encumber only the assets purchased, installed or otherwise acquired with the proceeds of such Environmental CapEx Debt or Necessary CapEx Debt;

        (9)   Liens encumbering deposits made to secure obligations arising from statutory, regulatory, contractual or warranty requirements of NRG or any Guarantor, including rights of offset and set-off;

        (10) Refinancing Liens;

        (11) Liens on the stock or assets of Project Subsidiaries securing Project Debt or tax equity financing of one or more Project Subsidiaries; and

        (12) other Liens, in addition to those permitted in clauses (1) through (11) above, securing Indebtedness having an aggregate principal amount, measured as of the date of creation of any such Lien and the date of incurrence of any such Indebtedness, not to exceed the greater of (i) 3% of Total Assets and (ii) $750.0 million.

Table of Contents

        Liens securing Indebtedness under the Credit Agreement existing on the date of the indenture will be deemed to have been incurred on such date in reliance on the exception provided by clause (1) above.

        If NRG or any Guarantor proposes to create or permit to exist any Lien upon any Principal Property owned by NRG or any Guarantor or upon any Equity Interests or Indebtedness of any direct or indirect Subsidiary of NRG to secure any Indebtedness, other than as permitted by clauses (1) through (12) of the previous paragraph, NRG will give prior written notice thereof to the trustee, who will give notice to the holders of notes, and NRG will further agree, prior to or simultaneously with the creation of such Lien, effectively to secure all the notes equally and ratably with (or prior to) such other Indebtedness, for so long as such other Indebtedness is so secured.

Merger, Consolidation or Sale of Assets

        NRG may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not NRG is the surviving corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of NRG and its Subsidiaries taken as a whole, in one or more related transactions, to another Person; unless:

        (1)   either: (a) NRG is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than NRG) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, partnership or limited liability company organized or existing under the laws of the United States, any state of the United States or the District of Columbia; provided that if the Person is a partnership or limited liability company, then a corporation wholly-owned by such Person organized or existing under the laws of the United States, any state of the United States or the District of Columbia that does not and will not have any material assets or operations shall become a co-issuer of the notes pursuant to a supplemental indenture duly executed by the trustee;

        (2)   the Person formed by or surviving any such consolidation or merger (if other than NRG) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of NRG under the notes and the indenture pursuant to a supplemental indenture or other documents and agreements reasonably satisfactory to the trustee; and

        (3)   immediately after such transaction, no Default or Event of Default exists.

        In addition, NRG may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person.

        This "Merger, Consolidation or Sale of Assets" covenant will not apply to (1) a merger of NRG with an Affiliate solely for the purpose of reincorporating NRG in another jurisdiction or forming a direct or indirect holding company of NRG; and (2) any sale, transfer, assignment, conveyance, lease or other disposition of assets between or among NRG and its Subsidiaries, including by way of merger or consolidation.

Additional Subsidiary Guarantees

        If,

        (1)   NRG or any of its Subsidiaries acquires or creates another Subsidiary after the issue date and such Subsidiary Guarantees any Obligations of NRG under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time), or

        (2)   any Subsidiary that does not currently Guarantee any Obligations of NRG under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced

36

Table of Contents

from time to time) subsequently Guarantees any Obligations of NRG under the Credit Agreement, or

        (3)   if there is no Indebtedness of NRG outstanding under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time) at that time, any Subsidiary of NRG (including any newly acquired or created Subsidiary) Guarantees any Obligations with respect to any other Indebtedness for borrowed money of NRG,

then such newly acquired or created Subsidiary or Subsidiary that subsequently Guarantees obligations under the Credit Agreement or other Indebtedness for borrowed money of NRG, as the case may be, will become a Guarantor of the notes and execute a supplemental indenture and deliver an opinion of counsel satisfactory to the trustee within 60 business days of the date on which it was acquired or created or guaranteed other Indebtedness for borrowed money of NRG, as the case may be.

Reports

        Whether or not required by the Commission's rules and regulations, so long as any notes are outstanding, NRG will furnish to the holders of notes or cause the trustee to furnish to the holders of notes, within the time periods (including any extensions thereof) specified in the Commission's rules and regulations:

        (1)   all quarterly and annual reports that would be required to be filed with the Commission on Forms 10-Q and 10-K if NRG were required to file such reports; and

        (2)   all current reports that would be required to be filed with the Commission on Form 8-K if NRG were required to file such reports.

        All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on NRG's consolidated financial statements by NRG's independent registered public accounting firm. In addition, NRG will file a copy of each of the reports referred to in clauses (1) and (2) above with the Commission for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the Commission will not accept such a filing). To the extent such filings are made, the reports will be deemed to be furnished to the trustee and holders of notes.

        If NRG is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, NRG will nevertheless continue filing the reports specified in the preceding paragraph with the Commission within the time periods specified above unless the Commission will not accept such a filing. NRG agrees that it will not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the foregoing, the Commission will not accept NRG's filings for any reason, NRG will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if NRG were required to file those reports with the Commission.

        In addition, NRG and the Guarantors agree that, for so long as any notes remain outstanding, at any time they are not required to file the reports required by the preceding paragraphs with the Commission, they will furnish to the holders of the notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Events of Default and Remedies

        Each of the following is an Event of Default with respect to the notes:

        (1)   default for 30 days in the payment when due of interest on the notes;

        (2)   default in payment when due of the principal of, or premium, if any, on the notes;

37

Table of Contents

        (3)   failure by NRG or any Guarantor for 60 days after written notice given by the trustee or the holders of at least 25% in aggregate principal amount of the notes that are then outstanding, to comply with any of the other agreements in the indenture;

        (4)   default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by NRG or any Guarantor (or the payment of which is guaranteed by NRG or any Guarantor) whether such Indebtedness or guarantee now exists, or is created after the issue date, if that default:

        (a)   is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default"); or

        (b)   results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, exceeds the greater of (i) 1.5% of Total Assets and (ii) $375.0 million;

provided that this clause (4) shall not apply to (i) secured Indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such Indebtedness to a Person that is not an Affiliate of NRG; (ii) Non-Recourse Debt (except to the extent that NRG or any of the Guarantors that are not parties to such Non-Recourse Debt becomes directly or indirectly liable, including pursuant to any contingent obligation, for any such Non-Recourse Debt and such liability, individually or in the aggregate, exceeds the greater of (a) 1.5% of Total Assets and (b) $375.0 million), and (iii) to the extent constituting Indebtedness, any indemnification, guarantee or other credit support obligations of NRG or any of the Guarantors in connection with any tax equity financing entered into by a non-Guarantor Subsidiary;

        (5)   one or more judgments for the payment of money in an aggregate amount in excess of the greater of (i) 1.5% of Total Assets and (ii) $375.0 million (excluding therefrom any amount reasonably expected to be covered by insurance) shall be rendered against NRG or any Guarantor or Guarantors or any combination thereof and the same shall not have been paid, discharged or stayed for a period of 60 days after such judgment became final and non-appealable;

        (6)   except as permitted by the indenture, any Subsidiary Guarantee shall be held in any final and non-appealable judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor (or any group of Guarantors) that constitutes a Significant Subsidiary, or any Person acting on behalf of any Guarantor (or any group of Guarantors) that constitutes a Significant Subsidiary, shall deny or disaffirm its or their obligations under its or their Subsidiary Guarantee(s); and

        (7)   certain events of bankruptcy or insolvency described in the indenture with respect to NRG or any Guarantor that is a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary.

        In the case of an Event of Default with respect to the notes arising from certain events of bankruptcy or insolvency with respect to NRG, any Guarantor or any group of Guarantors that, taken together, would constitute a Significant Subsidiary, all such notes that are outstanding will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of such notes that are outstanding may declare all the notes to be due and payable immediately.

        Subject to certain limitations, holders of a majority in principal amount of the notes that are then outstanding may direct the trustee in its exercise of any trust or power. The trustee may withhold from

38

---

Table of Contents

holders of the notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest.

        Subject to the provisions of the indenture relating to the duties of the trustee, in case an Event of Default occurs and is continuing under the indenture, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any holders of the notes unless such holders have offered to the trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder of a note may pursue any remedy with respect to the indenture unless:

        (1)   such holder has previously given the trustee written notice that an Event of Default is continuing;

        (2)   holders of at least 25% in aggregate principal amount of the notes that are then outstanding make a written request the trustee to pursue the remedy;

        (3)   such holders have offered the trustee reasonable security or indemnity against any loss, liability or expense;

        (4)   the trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

        (5)   holders of a majority in aggregate principal amount of the notes that are then outstanding have not given the trustee a direction inconsistent with such request within such 60-day period.

        The holders of a majority in aggregate principal amount of the notes then outstanding by written notice to the trustee may, on behalf of the holders of all of the notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, such notes.

        NRG is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, NRG is required to deliver to the trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

        No director, officer, employee, incorporator or stockholder of NRG or any Guarantor, as such, will have any liability for any obligations of NRG or the Guarantors under the notes, the indenture or the Subsidiary Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

        NRG may, at its option and at any time, elect to have all of its obligations discharged with respect to the notes that are outstanding and all obligations of the Guarantors of such notes discharged with respect to their Subsidiary Guarantees ("Legal Defeasance") except for:

        (1)   the rights of holders of the notes that are then outstanding to receive payments in respect of the principal of, or interest or premium on such notes when such payments are due from the trust referred to below;

        (2)   NRG's obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;

39

Table of Contents

        In addition, NRG may, at its option and at any time, elect to have the obligations of NRG and the Guarantors released with respect to certain covenants (including its obligation to make Change of Control Offers) that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under "—Events of Default and Remedies" will no longer constitute an Event of Default with respect to the notes.

        In order to exercise either Legal Defeasance or Covenant Defeasance:

        (1)   NRG must irrevocably deposit with the trustee, in trust, for the benefit of the holders of the notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants to pay the principal of, or interest and premium on such notes that are then outstanding on the Stated Maturity or on the applicable redemption date, as the case may be, and NRG must specify whether such notes are being defeased to maturity or to a particular redemption date;

        (2)   in the case of Legal Defeasance, NRG has delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that (a) NRG has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the issue date, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such opinion of counsel will confirm that, the holders of the notes that are then outstanding will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

        (3)   in the case of Covenant Defeasance, NRG has delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that the holders of the notes that are then outstanding will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

        (4)   no Default or Event of Default with respect to the notes has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

        (5)   such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the indenture and the agreements governing other Indebtedness being defeased, discharged or replaced) to which NRG or any of its Subsidiaries is a party or by which NRG or any of its Subsidiaries is bound;

        (6)   NRG must deliver to the trustee an officers' certificate stating that the deposit was not made by NRG with the intent of preferring the holders of the notes over the other creditors of NRG with the intent of defeating, hindering, delaying or defrauding creditors of NRG or others; and

        (1)   to cure any ambiguity, mistake, defect or inconsistency;

        (2)   to provide for uncertificated notes in addition to or in place of certificated notes;

        (2)   in respect of subclause (b) of clause (1) above, no Default or Event of Default under the indenture has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which NRG or any Guarantor is a party or by which NRG or any Guarantor is bound;

Concerning the Trustee

        If the trustee becomes a creditor of NRG or any Guarantor, the indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; provided that if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue (if the indenture has been qualified under the Trust Indenture Act) or resign.

        The holders of a majority in principal amount of the notes that are outstanding will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to the provisions of the indenture, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of notes, unless such holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

BOOK-ENTRY, DELIVERY AND FORM

        The Exchange Notes will be initially represented by one or more global notes in fully registered form without interest coupons (the "Global Notes"). The Global Notes will be deposited with the trustee, as custodian for DTC, in New York, New York, and registered in the name of DTC or its nominee, in each case for the credit to an account of a direct or indirect participant in DTC as described below. We expect that, pursuant to procedures established by DTC, (i) upon the issuance of the Global Notes, DTC or its custodian will credit, on its internal system, the principal amount at maturity of the individual beneficial interests represented by such Global Notes to the respective accounts of persons who have accounts with such depositary ("participants") and (ii) ownership of beneficial interests in the Global Notes will be shown on, and the transfer of such ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Such accounts initially will be designated by or on behalf of the initial purchasers and ownership of beneficial interests in the Global Notes will be limited to participants or persons who hold interests through participants. Holders may hold their interests in the Global Notes directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system.

        So long as DTC or its nominee is the registered owner or holder of the notes, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Notes for all purposes under the indenture. No beneficial owner of an interest in the Global Notes will be able to transfer that interest except in accordance with DTC's procedures, in addition to those provided for under the indenture with respect to the notes.

        Payments of the principal of, premium (if any), and interest on, the Global Notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. None of the Issuer, the trustee or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

        We expect that DTC or its nominee, upon receipt of any payment of principal of, premium (if any), and interest on the Global Notes, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Notes as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the Global Notes held through such participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

        Transfers between participants in DTC will be effected in the ordinary way through DTC's same-day funds system in accordance with DTC rules and will be settled in same-day funds.

        DTC has advised us that it will take any action permitted to be taken by a holder of notes (including the presentation of notes for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the indenture governing the notes, DTC will exchange the global notes for Certificated Notes (as defined below), which it will distribute to its participants.

        DTC has advised us as follows: DTC is a limited-purpose trust company organized under New York banking law, a "banking organization" within the meaning of the New York banking law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York

Table of Contents

Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for issues of U.S. and non-U.S. equity, corporate and municipal debt issues that participants deposit with DTC. DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between participants' accounts. This eliminates the need for physical movement of securities certificates. Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to the DTC system is also available to indirect participants such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

        Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among participants of DTC, it is under no obligation to perform such procedures, and such procedures may be discontinued at any time. None of us, the trustee or any paying agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Certificated Securities

        A Global Note is exchangeable for certificated notes in fully registered form without interest coupons ("Certificated Securities") only in the following limited circumstances:

•

DTC notifies us that it is unwilling or unable to continue as depositary for the Global Notes and we fail to appoint a successor depositary within 90 days of such notice, or



•

there shall have occurred and be continuing an event of default with respect to the notes under the indenture and DTC shall have requested the issuance of Certificated Securities.

        The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer the notes is and will be limited to such extent.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

        The following is a summary of certain U.S. federal income tax considerations relating to the exchange of Old Notes for Exchange Notes in the exchange offer. It does not contain a complete analysis of all the potential tax considerations relating to the exchange. This summary is limited to holders of Old Notes who hold the Old Notes as "capital assets" (in general, assets held for investment). Special situations, such as the following, are not addressed:

•

tax consequences to holders who may be subject to special tax treatment, such as tax-exempt entities, dealers in securities or currencies, banks, other financial institutions, insurance companies, regulated investment companies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings or corporations that accumulate earnings to avoid U.S. federal income tax;



•

tax consequences to persons holding notes as part of a hedging, integrated, constructive sale or conversion transaction or a straddle or other risk reduction transaction;



•

tax consequences to holders whose "functional currency" is not the U.S. dollar;



•

tax consequences to persons who hold notes through a partnership or similar pass-through entity;



•

U.S. federal gift tax, estate tax or alternative minimum tax consequences, if any; or



•

any state, local or non-U.S. tax consequences.

        The discussion below is based upon the provisions of the U.S. Internal Revenue Code of 1986, as amended, existing and proposed Treasury regulations promulgated thereunder, and rulings, judicial decisions and administrative interpretations thereunder, as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below.

Consequences of Tendering Old Notes

        The exchange of your Old Notes for Exchange Notes in the exchange offer should not constitute an exchange for U.S. federal income tax purposes because the Exchange Notes should not be considered to differ materially in kind or extent from the Old Notes. Accordingly, the exchange offer should have no U.S. federal income tax consequences to you if you exchange your Old Notes for Exchange Notes. For example, there should be no change in your tax basis and your holding period should carry over to the Exchange Notes. In addition, the U.S. federal income tax consequences of holding and disposing of your Exchange Notes should be the same as those applicable to your Old Notes.

        The preceding discussion of certain U.S. federal income tax considerations of the exchange offer is for general information only and is not tax advice. Accordingly, each investor should consult its own tax advisor as to particular tax consequences to it of exchanging Old Notes for Exchange Notes, including the applicability and effect of any state, local or non-U.S. tax laws, and of any proposed changes in applicable laws.

PLAN OF DISTRIBUTION

        Each broker-dealer that receives Exchange Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker or dealer in connection with resales of Exchange Notes received in exchange for Old Notes if the Old Notes were acquired as a result of market-making activities or other trading activities.

        We have agreed to make this prospectus, as amended or supplemented, available to any broker-dealer to use in connection with any such resale for a period of at least one year after the expiration date. In addition, until (90 days after the date of this prospectus), all broker-dealers effecting transactions in the Exchange Notes may be required to deliver a prospectus.

        We will not receive any proceeds from any sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions:

•

in the over-the-counter market;



•

in negotiated transactions; or



•

through the writing of options on the Exchange Notes or a combination of such methods of resale.

        These resales may be made:

•

at market prices prevailing at the time of resale;



•

at prices related to such prevailing market prices; or



•

at negotiated prices.

        Any such resale may be made directly to purchasers or to or through brokers or dealers. Brokers or dealers may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Notes. Any broker or dealer that resells Exchange Notes that were received by it for its own account in the exchange offer or that participants in a distribution of the Exchange Notes may be deemed to be an underwriter within the meaning of the Securities Act.

        Any profit on any resale of Exchange Notes and any commissions or concessions received by any broker or dealer may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

        Furthermore, any broker-dealer that acquired any of its Old Notes directly from us and any broker or dealer that participates in a distribution of the Exchange Notes:

•

may not rely on the applicable interpretation of the Staff of the SEC's position contained in Exxon Capital Holdings Corp., SEC no-action letter (April 13, 1988), Morgan, Stanley & Co. Inc., SEC no-action letter (June 5, 1991) and Shearman & Sterling, SEC no-action letter (July 2, 1993) and therefore may not participate in the exchange offer; and



•

must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale of the Old Notes.

        For a period of one year after the expiration of the exchange offer we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests those documents in the letter of transmittal. We have agreed to pay all expenses incident to performance of our obligations in connection with the exchange offer, other than commissions or concessions of any brokers or dealers. We will indemnify the holders of the Exchange Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act, and will contribute to payments that they may be required to make in request thereof.
