Unless the context otherwise requires or as otherwise indicated, references in this prospectus to "we," "our," "us," "the Company" and "Clearway" refer to Clearway Energy Operating LLC, together with its consolidated subsidiaries and direct parent Clearway Energy LLC ("Clearway LLC"). As of June 30, 2019, Clearway Energy, Inc. ("Clearway Inc.") (NYSE: CWEN.A, CWEN) owned approximately 55.8% of the economic interests in and was the sole managing member of Clearway LLC.

Our Company

We are an energy infrastructure investor in and owner of modern, sustainable and long-term contracted assets across North America. We are indirectly owned by Global Infrastructure Partners III ("GIP"). Global Infrastructure Management, LLC is an independent fund manager of funds that invests in infrastructure assets in the energy and transport sectors, and GIP is its third equity fund. We are sponsored by GIP through GIP's portfolio company, Clearway Energy Group LLC ("CEG").

Our environmentally sound asset portfolio includes over 5,272 Megawatts ("MW") of wind, solar and natural gas-fired power generation facilities, as well as district energy systems. Through this diversified and contracted portfolio, we endeavor to provide our investors with stable and growing dividend income. Substantially all of our generation assets are under long-term contractual arrangements for the output or capacity from these assets. The weighted average remaining contract duration of these offtake agreements was approximately 14 years as of June 30, 2019 based on Cash Available for Distribution ("CAFD"). We also own thermal infrastructure assets with an aggregate steam and chilled water capacity of 1,385 net Megawatts Thermal Equivalent ("MWt") and electric generation capacity of 133 net MW. These thermal infrastructure assets provide steam, hot and/or chilled water, and in some instances, electricity to commercial businesses, universities, hospitals and governmental units in multiple locations, principally through long-term contracts or pursuant to rates regulated by state utility commissions.

GIP Transaction

On August 31, 2018, NRG Energy, Inc. ("NRG") transferred its full ownership interest in us to CEG, the holder of NRG's renewable energy development and operations platform, and NRG subsequently sold 100% of its interest in CEG to an affiliate of GIP (the "GIP Transaction"). As a result of the GIP Transaction, GIP indirectly acquired a 45.2% economic interest in Clearway LLC and a 55.0% voting interest in us.

In connection with the GIP Transaction, Clearway Inc. entered into a Consent and Indemnity Agreement with NRG and GIP setting forth key terms and conditions of Clearway Inc.'s consent to the GIP Transaction.

Also in connection with the GIP Transaction, Clearway Inc. entered into the following agreements on August 31, 2018:

CEG Master Services Agreements. We, along with Clearway Inc. and Clearway LLC, entered into Master Services Agreements with CEG, pursuant to which CEG and certain of its affiliates or third-party service providers began providing certain services to Clearway Inc. and certain of its subsidiaries,

Table of Contents

and Clearway Inc. and certain of its subsidiaries began providing certain services to CEG, in exchange for the payment of fees in respect of such services.

ROFO Agreements. Clearway Inc. entered into a ROFO Agreement with CEG (the "CEG ROFO Agreement"), and a Third Amended and Restated ROFO Agreement with NRG (the "NRG ROFO Agreement").

Voting and Governance Agreement. Clearway Inc. entered into a Voting and Governance Agreement with CEG relating to certain governance matters of Clearway Inc.

Limited Liability Agreement. Clearway Inc. entered into the Fourth Amended and Restated Limited Liability Company Agreement of Clearway LLC with CEG, which sets forth the rights and obligations of Clearway Inc., as managing member, and CEG, as member, of Clearway LLC.

Transition Services Agreement. As a result of the GIP Transaction, Clearway LLC entered into a Transition Services Agreement with NRG ("NRG TSA"), pursuant to which NRG or certain of its affiliates began providing certain services to Clearway LLC following the consummation of the GIP Transaction on August 31, 2018, in exchange for the payment of a fee in respect of such services. A material portion of these processes terminated during the second quarter of 2019 and such services were subsequently provided by both Clearway LLC and by CEG pursuant to the CEG Master Services Agreements. During the second quarter of 2019, Clearway LLC exercised its option to extend the term of the NRG TSA through April 30, 2020 for the remaining services, some of which will be billed at an hourly rate as agreed between the parties.

Pacific Gas and Electric Company Bankruptcy

On January 29, 2019, Pacific Gas & Electric Company ("PG&E") filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of California (the "PG&E Bankruptcy"). Certain of our subsidiaries, which hold interests in 6 solar facilities totaling 480 MW and Marsh Landing with capacity of 720 MW, sell the output of their facilities to PG&E under long-term power purchase agreements ("PPAs"). We consolidate three of the solar facilities and Marsh Landing and record our interest in the other solar facilities as equity method investments. As of June 30, 2019, we had $1.4 billion of property, plant and equipment, net, $357 million investments in unconsolidated affiliates and $1.3 billion of borrowings with final maturity dates ranging from 2023 - 2038 related to these facilities. Our related subsidiaries are parties to financing agreements consisting of non-recourse project-level debt and, in certain cases, non-recourse holding company debt. The PG&E Bankruptcy triggered defaults under the PPAs with PG&E and such related project-level financing agreements. As a result, we recorded $1.3 billion of principal, net of the related unamortized debt issuance costs, as short-term debt as of June 30, 2019. As of August 5, 2019, our contracts with PG&E have operated in the normal course and we currently expect these contracts to continue as such. As of August 5, 2019, we have entered into forbearance agreements for certain project-level financing arrangements and continue to seek forbearance agreements for our other project-level financing arrangements affected by the PG&E Bankruptcy.

SUMMARY OF THE EXCHANGE OFFER

On October 1, 2018, we sold, through a private placement exempt from the registration requirements of the Securities Act, $600,000,000 of our 5.750% Senior Notes due 2025, which are eligible to be exchanged for Exchange Notes. We refer to these notes as "Old Notes" in this prospectus.

Simultaneously with the private placement, we entered into a registration rights agreement with the initial purchasers of the Old Notes (the "Registration Rights Agreement"). Under the Registration Rights Agreement, we are required to use commercially reasonable efforts to register Exchange Notes with the SEC having substantially identical terms as the Old Notes (except for the provisions relating to the transfer restrictions and payment of additional interest) as part of an offer to exchange freely tradable exchange notes for the notes, and use commercially reasonable efforts to consummate the exchange offer within 365 days after the issue date of the Old Notes. If required under certain circumstances, Clearway Operating LLC and the guarantors will file a shelf registration statement with the SEC covering resales of the notes.

We refer to the notes to be registered under this exchange offer registration statement as "Exchange Notes" and collectively with the Old Notes, we refer to them as the "notes" in this prospectus. You may exchange your Old Notes for the applicable Exchange Notes in this exchange offer. You should read the discussion under the headings "—Summary of Terms of Exchange Notes," "Exchange Offer" and "Description of the Notes" for further information regarding the Exchange Notes.


Exchange Notes offered		$600,000,000 aggregate principal amount of 5.750% Senior Notes due 2025.
Exchange offer		We are offering to exchange the Old Notes for a like principal amount at maturity of the Exchange Notes. Old Notes may be exchanged only in minimum principal amounts of $2,000 and integral multiples of $1,000 in excess thereof. The exchange offer is being made pursuant to the Registration Rights Agreement which grants the initial purchasers and any subsequent holders of the Old Notes certain exchange and registration rights. This exchange offer is intended to satisfy those exchange and registration rights with respect to the Old Notes. After the exchange offer is complete, you will no longer be entitled to any exchange or registration rights with respect to your Old Notes.
Expiration date; withdrawal of tender		The exchange offer will expire at 12:00 midnight, New York City time, on October 2, 2019, or a later time if we choose to extend this exchange offer in our sole and absolute discretion. You may withdraw your tender of Old Notes at any time prior to 12:00 midnight, New York City time, on the expiration date. All outstanding Old Notes that are validly tendered and not validly withdrawn will be exchanged. We will issue the Exchange Notes promptly after the expiration of the exchange offer. Any Old Note not accepted by us for exchange for any reason will be returned to you at our expense promptly after the expiration or termination of the exchange offer.

Table of Contents


Resales		We believe that you can offer for resale, resell and otherwise transfer the Exchange Notes without complying with the registration and prospectus delivery requirements of the Securities Act so long as:
		• you acquire the Exchange Notes in the ordinary course of business;
		• you are not participating, do not intend to participate, and have no arrangement or understanding with any person to participate, in the distribution of the Exchange Notes;
		• you are not an affiliate of ours; and
		• you are not a broker-dealer.
		If any of these conditions is not satisfied and you transfer any Exchange Notes without delivering a proper prospectus or without qualifying for a registration exemption, you may incur liability under the Securities Act. We do not assume, or indemnify you against, any such liability.
Broker-Dealer		Each broker-dealer acquiring Exchange Notes issued for its own account in exchange for Old Notes, which it acquired through market-making activities or other trading activities, must acknowledge that it will deliver a proper prospectus when any Exchange Notes issued in the exchange offer are transferred. A broker-dealer may use this prospectus for an offer to resell, a resale or other retransfer of the Exchange Notes issued in the exchange offer. See "Plan of Distribution."
Conditions to the exchange offer		Our obligation to accept for exchange, or to issue the Exchange Notes in exchange for, any Old Notes is subject to certain customary conditions, including our determination that the exchange offer does not violate any law, statute, rule, regulation or interpretation by the Staff of the SEC or any regulatory authority or other foreign, federal, state or local government agency or court of competent jurisdiction, some of which may be waived by us. We currently expect that each of the conditions will be satisfied and that no waivers will be necessary. See "Exchange Offer—Conditions to the exchange offer."
Procedures for tendering Old Notes held in the form of book-entry interests		The Old Notes were issued as global securities and were deposited upon issuance with Delaware Trust Company, which issued uncertificated depositary interests in those outstanding Old Notes, which represent a 100% interest in those Old Notes, to The Depositary Trust Company ("DTC").
		Beneficial interests in the outstanding Old Notes, which are held by direct or indirect participants in DTC, are shown on, and transfers of the Old Notes can only be made through, records maintained in book-entry form by DTC.

Table of Contents


		You may tender your outstanding Old Notes by instructing your broker or bank where you keep the Old Notes to tender them for you. In some cases you may be asked to submit the letter of transmittal that may accompany this prospectus. By tendering your Old Notes you will be deemed to have acknowledged and agreed to be bound by the terms set forth under "Exchange Offer." Your outstanding Old Notes must be tendered in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.
		In order for your tender to be considered valid, the exchange agent must receive a confirmation of book-entry transfer of your outstanding Old Notes into the exchange agent's account at DTC, under the procedure described in this prospectus under the heading "Exchange Offer," on or before 12:00 midnight, New York City time, on the expiration date of the exchange offer.
Special procedures for beneficial owners		If you are the beneficial owner of book-entry interests and your name does not appear on a security position listing of DTC as the holder of the book-entry interests or if you are a beneficial owner of Old Notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender the book-entry interest or Old Notes in the exchange offer, you should contact the person in whose name your book- entry interests or Old Notes are registered promptly and instruct that person to tender on your behalf.
U.S. federal income tax considerations		The exchange offer should not result in any income, gain or loss to the holders of Old Notes or to us for U.S. federal income tax purposes. See "Certain U.S. Federal Income Tax Consequences."
Use of proceeds		We will not receive any proceeds from the issuance of the Exchange Notes in the exchange offer.
Exchange agent		Delaware Trust Company is serving as the exchange agent for the exchange offer.
Shelf registration statement		In limited circumstances, holders of Old Notes may require us to register their Old Notes under a shelf registration statement.

Table of Contents

CONSEQUENCES OF NOT EXCHANGING OLD NOTES

If you do not exchange your Old Notes in the exchange offer, your Old Notes will continue to be subject to the restrictions on transfer currently applicable to the Old Notes. In general, you may offer or sell your Old Notes only:

•: if they are registered under the Securities Act and applicable state securities laws;
•: if they are offered or sold under an exemption from registration under the Securities Act and applicable state securities laws; or
•: if they are offered or sold in a transaction not subject to the Securities Act and applicable state securities laws.

We do not currently intend to register the Old Notes under the Securities Act. Under some circumstances, however, holders of the Old Notes, including holders who are not permitted to participate in the exchange offer or who may not freely resell Exchange Notes received in the exchange offer, may require us to file, and to cause to become effective, a shelf registration statement covering resales of notes by these holders. For more information regarding the consequences of not tendering your Old Notes and our obligation to file a shelf registration statement, see "Exchange Offer—Consequences of failure to exchange."

SUMMARY OF TERMS OF EXCHANGE NOTES

The summary below describes the principal terms of the Exchange Notes, the guarantees and the related indenture. Certain of the terms and conditions described below are subject to important limitations and exceptions. The "Description of the Notes" section of this prospectus contains more detailed descriptions of the terms and conditions of the Exchange Notes and the related indenture.


Issuer		Clearway Energy Operating LLC
Securities offered		$600 million in aggregate principal amount of 5.750% Senior Notes due 2025. The Exchange Notes will evidence the same debt as the Old Notes.
Maturity date		The Exchange Notes will mature on October 15, 2025.
Interest rate		The Exchange Notes will accrue interest at the rate of 5.750% per annum.
Interest payment dates		Interest on the Exchange Notes will be payable on April 15 and October 15 of each year. The Exchange Notes will accrue interest from and including the last interest payment date on which interest has been paid on the Old Notes.
		No interest will be paid on either the Exchange Notes or the Old Notes at the time of exchange. Accordingly, the holders of Old Notes that are accepted for exchange will not receive accrued but unpaid interest on such Old Notes at the time of tender. Rather, that interest will be payable on the Exchange Notes delivered in exchange for the Old Notes on the first interest payment date following the expiration date of the exchange offer.
Ranking		The Exchange Notes will:
		• be general unsecured obligations of Clearway Operating LLC;
		• bepari passu in right of payment with all existing and future senior indebtedness of Clearway Operating LLC, including Clearway Operating LLC's indebtedness under the Revolving Credit Facility (as defined herein);
		• be senior in right of payment to any future subordinated indebtedness of Clearway Operating LLC; and
		• be guaranteed as described under "—Parent Guarantee" and "—Subsidiary Guarantees".

Table of Contents


		The Exchange Notes will be effectively subordinated to all borrowings under the Revolving Credit Facility, which is secured by substantially all of the assets of Clearway Operating LLC and the guarantors of the Exchange Notes, and any other secured indebtedness (including any secured hedging obligations) of Clearway Operating LLC or the guarantors of the notes, in each case to the extent of the value of the assets that secure the Revolving Credit Facility or such 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."
Parent Guarantee		The Exchange Notes will be guaranteed by Clearway LLC, Clearway Operating LLC's parent company (the "Parent Guarantor"). The parent guarantee of the Exchange Notes will:
		• be a general unsecured obligation of the Parent Guarantor;
		• bepari passu in right of payment with all existing and future senior indebtedness of the Parent Guarantor, including the Parent Guarantor's guarantee under the Revolving Credit Facility; and
		• be senior in right of payment to any future subordinated indebtedness of the Parent Guarantor.
		The Parent Guarantor's guarantee of the Exchange Notes will be effectively subordinated to the Parent Guarantor's guarantee under the Revolving Credit Facility and any other secured indebtedness of the Parent Guarantor (including any hedging obligations), in each case, to the extent of the value of the assets of the Parent Guarantor that secure the Revolving Credit Facility or such other secured indebtedness.
Subsidiary Guarantees		In addition to the guarantee by the Parent Guarantor, the Exchange Notes will be guaranteed on a joint and several basis by each wholly-owned subsidiary of Clearway Operating LLC that guarantees any obligations of Clearway Operating LLC under the Revolving Credit Facility or any other material indebtedness of Clearway Operating LLC, from time to time. Each subsidiary guarantee of the notes will:
		• be a general unsecured obligation of that subsidiary guarantor;
		• bepari passu in right of payment with all existing and future senior indebtedness of that subsidiary guarantor, including the subsidiary guarantor's guarantee under the Revolving Credit Facility; and
		• be senior in right of payment to any future subordinated indebtedness of that subsidiary guarantor.

Table of Contents


		Each subsidiary guarantor's guarantee of the Exchange Notes will be effectively subordinated to such subsidiary guarantor's guarantee under the Revolving Credit Facility and any other secured indebtedness of such subsidiary guarantor (including any hedging obligations), in each case, to the extent of the value of the assets of such subsidiary guarantor that secures the Revolving Credit Facility or such other secured indebtedness.
		Our operations are primarily conducted through our subsidiaries and, therefore, we will depend on the cash flow of our subsidiaries to meet our obligations under the notes. Not all of our subsidiaries will guarantee the Exchange Notes.
		The Exchange Notes will be structurally subordinated in right of payment to all indebtedness and other liabilities and commitments of our non- guarantor subsidiaries. The subsidiary guarantors accounted for approximately 1% of Clearway Operating LLC's revenues from operations for the fiscal year ended December 31, 2018 and the six months ended June 30, 2019, respectively. As of June 30, 2019, Clearway Operating LLC's non-guarantor subsidiaries had approximately $2,757 million in aggregate principal amount of non-current liabilities and outstanding trade payables of approximately $57 million. See "Risk Factors—Risks related to the notes—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."
Optional redemption		Prior to October 15, 2021, we may redeem up to 35% of the notes with an amount equal to the net cash proceeds of certain equity offerings at the redemption price listed in the "Description of the Notes—Optional Redemption" section of this prospectus, plus accrued and unpaid interest;provided at least 65% of the aggregate principal amount of the notes remain outstanding after the redemption and the redemption occurs within 180 days of such equity offering.
		We may redeem some or all of the notes at any time prior to October 15, 2021 at a price equal to 100% of the principal amount of the notes redeemed plus a "make-whole" premium and accrued and unpaid interest.
		On or after October 15, 2021, we may redeem some or all of the notes at the redemption prices listed in the "Description of the Notes—Optional Redemption" section of this prospectus, plus accrued and unpaid interest.
Change of control offer		If a change of control triggering event occurs, subject to certain conditions, we must offer to repurchase the notes at a price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest to the date of repurchase. See "Description of the Notes—Repurchase at the option of holders—Change of control triggering event."

Table of Contents


Covenants		We have agreed to certain restrictions on incurring liens to secure indebtedness and certain restrictions on consolidating, merging and transferring all or substantially all of our assets. See "Description of the Notes—Certain Covenants."
Events of default		For a discussion of events that will permit acceleration of the payment of the principal of and accrued interest on the Exchange Notes, see "Description of the Notes—Events of default and remedies."
No prior market		The Exchange Notes will be new securities for which there is currently no market. We cannot assure you as to the liquidity of markets that may develop for the Exchange Notes, your ability to sell the notes or the price at which you would be able to sell the notes. See "Risk Factors—Risks related to the notes—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 market will develop for the notes."
Listing		We do not intend to list the Exchange Notes on any securities exchange.
Use of proceeds		We will not receive any proceeds from the issuance of the Exchange Notes. See "Use of Proceeds."
Form and denomination		The Exchange Notes will be delivered in fully-registered form.

Beneficial interests in the global notes will be shown on, and any transfers will be effective only through records maintained by DTC and its participants. The Exchange Notes will be issued in denominations of $2,000 and integral multiples of $1,000.
Governing law		The Exchange Notes and the indenture governing the Exchange Notes will be governed by, and construed in accordance with, the laws of the State of New York.
Trustee		Delaware Trust Company.

The selected risks described below and the risks that are incorporated into this prospectus by reference to our 2018 Form 10-K, the First Quarter Form 10-Q and the Second Quarter Form 10-Q 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 2018 Form 10-K, the First Quarter Form 10-Q and the Second Quarter Form 10-Q 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 Revolving Credit Facility, will be adequate to meet our future liquidity needs for at least the next twelve 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 Revolving 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.

Table of Contents

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 Revolving 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 in our remaining assets 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 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, 2019, we had approximately $4,245 million of project-level debt which was incurred by our non-guarantor subsidiaries. In addition, our share of our unconsolidated affiliates' total indebtedness and letters of credit outstanding, as of June 30, 2019, totaled approximately $943 million and $80 million, respectively (calculated as our unconsolidated affiliates' total indebtedness as of such date multiplied by our percentage membership interest in such assets). We also had $491 million of letters of credit outstanding to support contracted obligations at our project-level entities as of June 30, 2019. 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.

Table of Contents

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 that restrictions in our Revolving Credit Facility or other senior indebtedness will not allow such repurchases. In addition, 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, is greater than the fair saleable value of all of its assets; or
•: if the present fair saleable value of its assets is 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 the 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.

Table of Contents

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 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 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.

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 in order to receive new, freely tradable 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;

Table of Contents

•: 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 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 October 1, 2018, to the initial purchasers, pursuant to the purchase agreement dated September 17, 2018. 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

Table of Contents

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 2, 2019, 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

Table of Contents

•: 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;

•

if you or another person acquiring Exchange Notes in exchange for Old Notes in the exchange offer is a broker dealer:

•: the Old Notes to be exchanged for Exchange Notes were acquired as a result of market-making activities or other trading activities;
•: neither you nor any other person acquiring Exchange Notes for your Old Notes in the exchange offer has entered into any arrangement or understanding with the Issuer or an affiliate of the Issuer to distribute the Exchange Notes; and
•: you or such other person acquiring Exchange Notes for your Old Notes in the exchange offer will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes (by so representing 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); and
•: 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

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 2, 2019.

You may tender some or all of your Old Notes in this exchange offer. However, your Old Notes may be tendered only in minimum principal amounts of $2,000 and integral multiples of $1,000 in excess thereof.

Table of Contents

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.

�� 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

Table of Contents

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

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.

Table of Contents

•

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 clauses (1), (2) or (3) 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:

any change, or any development involving a prospective change, has occurred or been threatened in our business, financial condition, operations or prospects and those of our subsidiaries taken as a whole that is or may be adverse to us, or we have become aware of facts that have or may have an adverse impact on the value of the Old Notes or the Exchange Notes;

•

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

Table of Contents

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.

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:

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.

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.

Table of Contents

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 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

Table of Contents

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

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.

DESCRIPTION OF THE NOTES

In this description, "Clearway Energy Operating LLC" refers only to Clearway Energy Operating LLC and not to any of its subsidiaries or parent entities.

Clearway Energy Operating LLC issued the Old Notes under an indenture (the "indenture") among Clearway Energy Operating LLC, the Guarantors named therein and Delaware Trust Company, as trustee. 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 Clearway Energy Operating LLC. 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 Clearway Energy Operating LLC;
•: will bepari passu in right of payment with all existing and future senior Indebtedness of Clearway Energy Operating LLC, including Clearway Energy Operating LLC's Indebtedness under the Credit Agreement;
•: will be senior in right of payment to any future subordinated Indebtedness of Clearway Energy Operating LLC; and
•: will be unconditionally guaranteed on a joint and several basis by the Guarantors.

The notes will be effectively subordinated to all borrowings under the Credit Agreement, which is secured by substantially all of the assets of Clearway Energy Operating LLC and the Guarantors, and any other secured Indebtedness (including any secured Hedging Obligations) of Clearway Energy Operating LLC or the Guarantors, in each case to the extent of the value of the assets that secure the Credit Agreement or such 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."

Table of Contents

The Parent Guarantor

The notes will be guaranteed by Clearway LLC (the "Parent Guarantor"). The Parent Guarantee of the notes:

•: will be a general unsecured obligation of the Parent Guarantor;
•: will bepari passu in right of payment with all existing and future senior Indebtedness of the Parent Guarantor, including the Parent Guarantor's guarantee under the Credit Agreement; and
•: will be senior in right of payment to any future subordinated Indebtedness of the Parent Guarantor.

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

The Subsidiary Guarantors

In addition to the Parent Guarantee, the notes will initially be guaranteed by each Wholly Owned Subsidiary of Clearway Energy Operating LLC that guarantees any obligations of Clearway Energy Operating LLC under the Credit Agreement of Clearway Energy Operating LLC. Each Subsidiary Guarantee of the notes:

•: will be a general unsecured obligation of the Subsidiary Guarantor;
•: will bepari passu in right of payment with all existing and future senior Indebtedness of that Subsidiary Guarantor, including such Subsidiary Guarantor's guarantee under the Credit Agreement; and
•: will be senior in right of payment to any future subordinated Indebtedness of that Subsidiary Guarantor.

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

The operations of Clearway Energy Operating LLC are primarily conducted through its subsidiaries and, therefore, Clearway Energy Operating LLC depends on the cash flow of its subsidiaries to meet its obligations, including its obligations under the notes. Not all of Clearway Energy Operating LLC'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, project financing and other indebtedness for borrowed money and Hedging Obligations) of these non-guarantor subsidiaries. Any right of Clearway Energy Operating LLC 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 Clearway Energy Operating LLC 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 Clearway Energy Operating LLC. The Subsidiary Guarantors accounted for approximately 1% of Clearway Energy Operating LLC's revenues from operations for the fiscal year ended December 31, 2018 and the six months ended June 30, 2019. The

Table of Contents

Subsidiary Guarantors held approximately 9% of Clearway Energy Operating LLC's consolidated assets as of June 30, 2019. As of June 30, 2019, Clearway Energy Operating LLC's non-guarantor subsidiaries had approximately $2,757 million in aggregate principal amount of non-current liabilities and outstanding trade payables of approximately $57 million.

Principal, Maturity and Interest

Clearway Energy Operating LLC will issue up to $600.0 million aggregate principal amount of Exchange Notes in this offering. Clearway Energy Operating LLC may issue additional notes of the same series under the indenture from time to time after this offering. Any issuance of additional notes is subject to all of the covenants in the indenture. The notes 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.

Clearway Energy Operating LLC will issue notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will mature on October 15, 2025.

Interest will accrue at the rate of 5.750% per annum, and will be payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2019. Clearway Energy Operating LLC will make each interest payment to the holders of record on the immediately preceding April 1 and October 1, respectively.

Interest on the notes will accrue from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Methods of Receiving Payments on the Notes

If a holder of notes has given wire transfer instructions to Clearway Energy Operating LLC, Clearway Energy Operating LLC 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 Clearway Energy Operating LLC elects to make interest payments by check mailed to the holders of the notes at their address set forth in the register of holders.

Paying Agent and Registrar for the Notes

The trustee will initially act as paying agent and registrar. Clearway Energy Operating LLC may change the paying agent or registrar without prior notice to the holders of the notes, and Clearway Energy Operating LLC or any of its Subsidiaries or parent entities 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. Clearway Energy Operating LLC is not required to transfer or exchange any note selected for redemption. Also, Clearway Energy Operating LLC is not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

Parent Guarantee

Clearway Energy Operating LLC's payment obligations under the notes will be guaranteed on a full and unconditional basis by the Parent Guarantor. The obligations of the Parent Guarantor under the Parent Guarantee will be limited as necessary to prevent the Parent Guarantee from constituting a

Table of Contents

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 holders of the notes to return payments received from guarantors."

Subsidiary Guarantees

Clearway Energy Operating LLC's payment obligations under the notes will be guaranteed on a full and unconditional basis by each of the Subsidiary Guarantors. These Subsidiary Guarantees will be joint and several obligations of the Subsidiary Guarantors. The obligations of each Subsidiary 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 Subsidiary Guarantor will be released automatically:

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

(2) in connection with any sale or other disposition of Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) Clearway Energy Operating LLC or a Subsidiary of Clearway Energy Operating LLC, if following such sale or other disposition, that Subsidiary Guarantor is no longer a direct or indirect Subsidiary of Clearway Energy Operating LLC;

(c) if Clearway Energy Operating LLC has Indebtedness outstanding under the Credit Agreement at that time, upon the release of such Subsidiary Guarantor's Guarantee of all Obligations of Clearway Energy Operating LLC under the Credit Agreement, or, if there is no Indebtedness of Clearway Energy Operating LLC outstanding under the Credit Agreement at that time, upon the release of such Subsidiary Guarantor's Guarantee of all Obligations with respect to all other Material Indebtedness of Clearway Energy Operating LLC at that time outstanding.

The provisions described above that require Clearway Energy Operating LLC 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 Clearway Energy Operating LLC repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

Clearway Energy Operating LLC 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 Clearway Energy Operating LLC 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 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,

Table of Contents

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 not withdraw such notes in a Change of Control Offer and Clearway Energy Operating, or any third party making a Change of Control Offer in lieu of Clearway Energy Operating as described above, purchases all of the notes validly tendered and not withdrawn by such holders, all of the Holders of the Notes will be deemed to have validly tendered their notes and not withdrawn and, accordingly, Clearway Energy Operating 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 Clearway Energy Operating LLC 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 Clearway Energy Operating LLC to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of Clearway Energy Operating LLC 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 or applicable stock exchange 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 Clearway Energy Operating LLC's discretion, be subject to the satisfaction of one or more conditions precedent. If a redemption notice is subject to satisfaction of one or more conditions precedent, such notice will state that, at Clearway Energy Operating LLC's discretion, the redemption date may be delayed until such time as any or all such conditions are satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions have not been satisfied by the redemption date, or by the redemption date so delayed.

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 so long as Clearway Energy Operating LLC has deposited with the paying agent funds sufficient to pay the principal of, plus accrued and unpaid interest and premium, if any, on, the notes to be redeemed.

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. For purposes of determining compliance with this "Liens" covenant, in the event that a proposed Lien meets the criteria of more than one of the categories of Liens described in clauses (1) through (13) above, Clearway Energy Operating LLC will be permitted to classify such Lien on the date of its incurrence, or later reclassify all or a portion of such Lien, in any manner that complies with this covenant.

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 the Parent Guarantor or Clearway Energy Operating LLC, as the case may be) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Parent Guarantor or Clearway Energy Operating LLC, as the case may be, under the notes and the indenture pursuant to a supplemental indenture or other documents and agreements reasonably satisfactory to the trustee; and

If,

(1) Clearway Energy Operating LLC or any of its Subsidiaries acquires or creates another Wholly Owned Subsidiary after the issue date and such Wholly Owned Subsidiary Guarantees any Obligations of Clearway Energy Operating LLC under the Credit Agreement, or

(2) any Wholly Owned Subsidiary of Clearway Energy Operating LLC that does not currently Guarantee any Obligations of Clearway Energy Operating LLC under the Credit Agreement subsequently Guarantees any Obligations of Clearway Energy Operating LLC under the Credit Agreement, or

(3) if there is no Indebtedness of Clearway Energy Operating LLC outstanding under the Credit Agreement at that time, any Wholly Owned Subsidiary of Clearway Energy Operating LLC (including any newly acquired or created Wholly Owned Subsidiary) Guarantees any Obligations with respect to any other Material Indebtedness of Clearway Energy Operating LLC, then such newly acquired or created Wholly Owned Subsidiary or Wholly Owned Subsidiary that subsequently fully and unconditionally Guarantees obligations under the Credit Agreement or other Material Indebtedness of Clearway Energy Operating LLC, 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 Material Indebtedness of Clearway Energy Operating LLC, as the case may be.

(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;

(3) failure by Clearway Energy Operating LLC 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 Clearway Energy Operating LLC or any Guarantor (or the payment of which is guaranteed by Clearway Energy Operating LLC 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) $100.0 million;

Table of Contents

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 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, if Subsidiaries of Clearway Energy Operating LLC, would constitute a Significant Subsidiary, or any Person acting on behalf of any Guarantor (or any group of Guarantors) that, if Subsidiaries of Clearway Energy Operating LLC, would constitute a Significant Subsidiary, shall deny or disaffirm its or their obligations under its or their Guarantee(s); and

(7) certain events of bankruptcy or insolvency described in the indenture with respect to Clearway Energy Operating LLC or any Guarantor that, if a Subsidiary of Clearway Energy Operating LLC, would constitute a Significant Subsidiary or any group of Guarantors that, if Subsidiaries of Clearway Energy Operating LLC, 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 Clearway Energy Operating LLC, any Guarantor or any group of Guarantors that, if subsidiaries of Clearway Energy Operating LLC, 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 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 have made a written request to 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 the notes, rescind an acceleration or waive any

Table of Contents

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.

Clearway Energy Operating LLC 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, Clearway Energy Operating LLC 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, stockholder, member or unitholder of Clearway Energy Operating LLC or any Guarantor, as such, will have any liability for any obligations of Clearway Energy Operating LLC or the Guarantors under the notes, the indenture or the 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

Clearway Energy Operating LLC 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 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) Clearway Energy Operating LLC'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;

(3) the rights, powers, trusts, duties and immunities of the trustee for the notes, and Clearway Energy Operating LLC's and the Guarantors' obligations in connection therewith; and

(4) the Legal Defeasance provisions of the indenture governing such notes.

In addition, Clearway Energy Operating LLC may, at its option and at any time, elect to have the obligations of Clearway Energy Operating LLC 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) Clearway Energy Operating LLC 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 Clearway Energy Operating LLC must specify whether such notes are being defeased to maturity or to a particular redemption date;

Table of Contents

(2) in the case of Legal Defeasance, Clearway Energy Operating LLC has delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that (a) Clearway Energy Operating LLC 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 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 federal income tax purposes as a result of such Legal Defeasance and will be subject to 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, Clearway Energy Operating LLC 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 federal income tax purposes as a result of such Covenant Defeasance and will be subject to 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 Clearway Energy Operating LLC or any of its Subsidiaries or the Parent Guarantor is a party or by which Clearway Energy Operating LLC or any of its Subsidiaries or the Parent Guarantor is bound;

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

(7) Clearway Energy Operating LLC must deliver to the trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, the indenture or the notes outstanding thereunder may be amended or supplemented with the consent of the holders of at least a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the notes), and any existing default or compliance with any provision of the indenture or the notes outstanding thereunder may be waived with the consent of the holders of a majority in principal amount of the notes that are then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the notes).

Without the consent of each holder of the notes affected thereby, an amendment or waiver may not (with respect to any such notes held by a non-consenting holder):

Table of Contents

(2) reduce the principal of or change the fixed maturity of any such note or alter the provisions with respect to the redemption of such notes (other than provisions relating to the covenants described above under the caption "—Repurchase at the Option of Holders" and provisions relating to the number of days of notice to be given in the event of a redemption);

(3) reduce the rate of or change the time for payment of interest on any such note;

Notwithstanding the preceding, without the consent of any holder of notes, Clearway Energy Operating LLC, the Guarantors and the trustee may amend or supplement the indenture or the notes:

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

(2) to provide for uncertificated notes in addition to or in place of certificated notes (provided, that the uncertificated notes are issued in registered form for purposes of Section 163(f) of the Code);

(3) to provide for the assumption of Clearway Energy Operating LLC's obligations to holders of notes in the case of a merger or consolidation or sale of all or substantially all of Clearway Energy Operating LLC's assets;

(4) to make any change that would provide any additional rights or benefits to the holders of notes or that does not adversely affect the legal rights under any indenture of any such holder;

(5) to comply with requirements of the Commission in order to effect or maintain the qualification of any indenture under the Trust Indenture Act;

(6) to conform the text of the indenture or the notes to any provision of this "Description of the Notes";

Table of Contents

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect as to all notes issued thereunder, when:

(1) either:

BOOK-ENTRY, DELIVERY AND FORM

The Exchange Notes initially will be 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.
