The Company is sponsored by GIP and TotalEnergies through the portfolio company, Clearway Energy Group LLC, or CEG, which became equally owned by GIP and TotalEnergies as of September 12, 2022, when TotalEnergies acquired, through its investment in an intermediate holding company, 50% of GIP’s interest in CEG. GIP is an independent infrastructure fund manager that makes equity and debt investments in infrastructure assets and businesses. TotalEnergies is a global multi-energy company. The Company is one of the largest renewable energy owners in the U.S. with over 5,500 net MW of installed wind and solar generation projects. The Company’s over 8,000 net MW of assets also includes approximately 2,500 net MW of environmentally-sound, highly efficient natural gas-fired generation facilities. Through this environmentally-sound, diversified and primarily contracted portfolio, the Company endeavors to increase distributions to its unit holders. Substantially all of the Company’s generation assets are under long-term contractual arrangements for the output or capacity from these assets. On May 1, 2022, the Company completed the sale of 100% of its interests in the Thermal Business to KKR. For further details of the Thermal Disposition, refer to Note 3, Acquisitions and Dispositions .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amounts of net earnings during the reporting periods. Actual results could be different from these estimates. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include highly liquid investments with an original maturity of three months or less at the time of purchase. Cash and cash equivalents held at project subsidiaries was $168 million and $146 million as of September 30, 2022 and December 31, 2021, respectively. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows: September 30, 2022 December 31, 2021 (In millions) Cash and cash equivalents $ 793 $ 179 Restricted cash 363 475 Cash, cash equivalents and restricted cash shown in the consolidated statements of cash flows $ 1,156 $ 654 Restricted cash consists primarily of funds held to satisfy the requirements of certain debt agreements and funds held within the Company’s projects that are restricted in their use. As of September 30, 2022, these restricted funds were comprised of $144 million designated to fund operating expenses, $66 million designated for current debt service payments and $124 million restricted for reserves including debt service, performance obligations and other reserves as well as capital expenditures. The remaining $29 million is held in distributions reserve accounts. In 2020, the members of the partnerships holding the Oahu Solar and Kawailoa Solar projects submitted applications to the state of Hawaii for refundable tax credits based on the cost of construction of the projects. In 2021, the members of the partnerships contributed their respective portions of the tax credits in the amount of $27 million to the Oahu Solar and $22 million to the Kawailoa Solar project companies, which were recorded to restricted cash on the Company’s consolidated balance sheet with an offsetting adjustment to noncontrolling interests. In accordance with the projects’ related agreements, the cash is held in a restricted account and utilized to offset invoiced amounts under the projects’ PPAs. On August 1, 2022, the Company sold its Class A interests in the Kawailoa Partnership, which consolidates the Kawailoa Solar project, to Clearway Renew LLC, as further described in Note 3, Acquisitions and Dispositions , resulting in the removal of $7 million that remained in restricted cash at the time of sale. As of September 30, 2022, $22 million of the $27 million previously contributed to the Oahu Solar projects has been utilized to offset invoiced amounts under the projects’ PPAs. Accumulated Depreciation and Accumulated Amortization The following table presents the accumulated depreciation included in property, plant and equipment, net, and accumulated amortization included in intangible assets, net as of September 30, 2022 and December 31, 2021: September 30, 2022 December 31, 2021 (In millions) Property, Plant and Equipment Accumulated Depreciation $ 3,124 $ 2,501 Intangible Assets Accumulated Amortization 728 605 Distributions The following table lists distributions paid on the Company's Class A, B, C and D units during the nine months ended September 30, 2022: Third Quarter 2022 Second Quarter 2022 First Quarter 2022 Distributions per Class A, B, C and D unit $ 0.3604 $ 0.3536 $ 0.3468 On November 2, 2022, the Company declared a distribution on its Class A, Class B, Class C and Class D units of $0.3672 per unit payable on December 15, 2022 to unit holders of record as of December 1, 2022. In addition to the quarterly distributions, the Company paid $19 million in additional distributions, $11 million of which was distributed to Clearway, Inc. and $8 million of which was distributed to CEG, during the third quarter of 2022 in order for Clearway, Inc. to make certain tax payments associated with the sale of the Thermal Business. Redeemable Noncontrolling Interests To the extent that a third party has the right to redeem their interests for cash or other assets, the Company has included the noncontrolling interest attributable to the third party as a component of temporary equity in the mezzanine section of the consolidated balance sheet. The following table reflects the changes in the Company’s redeemable noncontrolling interest balance for the nine months ended September 30, 2022: (In millions) Balances at December 31, 2021 $ — Cash distributions to redeemable noncontrolling interests (2) Comprehensive income attributable to redeemable noncontrolling interests 9 Balances at September 30, 2022 $ 7 Revenue Recognition Revenue from Contracts with Customers The Company applies the guidance in ASC 606, Revenue from Contracts with Customers, or Topic 606, when recognizing revenue associated with its contracts with customers. The Company’s policies with respect to its various revenue streams are detailed below. In general, the Company applies the invoicing practical expedient to recognize revenue for the revenue streams detailed below, except in circumstances where the invoiced amount does not represent the value transferred to the customer. Power Purchase Agreements, or PPAs The majority of the Company’s revenues are obtained through PPAs or similar contractual agreements. Energy, capacity and where applicable, renewable attributes, from the majority of the Company’s renewable energy assets and certain conventional energy plants is sold through long-term PPAs and tolling agreements to a single counterparty, which is often a utility or commercial customer. The majority of these PPAs are accounted for as operating leases as the Company retained its historical lease assessments and classification upon adoption of ASC 842, Leases . ASC 842 requires the minimum lease payments received to be amortized over the term of the lease and contingent rentals are recorded when the achievement of the contingency becomes probable. Judgment is required by management in determining the economic life of each generating facility, in evaluating whether certain lease provisions constitute minimum payments or represent contingent rent and other factors in determining whether a contract contains a lease and whether the lease is an operating lease or capital lease. Certain of these PPAs have no minimum lease payments and all of the lease revenue under these PPAs is recorded as contingent rent on an actual basis when the electricity is delivered. Renewable Energy Credits, or RECs Renewable energy credits, or RECs, are usually sold through long-term PPAs or through REC contracts with counterparties. Revenue from the sale of self-generated RECs is recognized when the related energy is generated and simultaneously delivered even in cases where there is a certification lag as it has been deemed to be perfunctory. In a bundled contract to sell energy, capacity and/or self-generated RECs, all performance obligations are deemed to be delivered at the same time and hence, timing of recognition of revenue for all performance obligations is the same and occurs over time. In such cases, it is often unnecessary to allocate transaction price to multiple performance obligations. Thermal Revenues Steam and chilled water revenue is recognized as the Company transfers the product to the customer, based on customer usage as determined by meter readings taken at month-end. Some locations read customer meters throughout the month and recognize estimated revenue for the period between meter read date and month-end. For thermal contracts, the Company’s performance obligation to deliver steam and chilled water is satisfied over time and revenue is recognized based on the invoiced amount. The Thermal Business subsidiaries collect, and remit state and local taxes associated with sales to their customers, as required by governmental authorities. These taxes are presented on a net basis in the consolidated statements of income. As contracts for steam and chilled water are long-term contracts, the Company has performance obligations under these contracts that have not yet been satisfied. These performance obligations have transaction prices that are both fixed and variable, and that vary based on the contract duration, customer type, inception date and other contract-specific factors. For the fixed price contracts, the Company cannot accurately estimate the amount of its unsatisfied performance obligations as it will vary based on customer usage, which will depend on factors such as weather and customer activity.

Lighthouse Renewable Holdco LLC is a partnership between the Company and a third-party investor. The third-party investor also contributed cash consideration of $12 million, which was utilized to acquire their portion of the acquired entity. Waiawa BL Borrower Holdco LLC consolidates, as the direct owner of the primary beneficiary, a tax equity fund, Waiawa TE Holdco LLC, which directly holds the Waiawa solar project. Waiawa has a 20-year PPA with an investment-grade utility that commences when the project reaches commercial operations, as defined in the PPA. The acquisition was funded with existing sources of liquidity. Capistrano Wind Portfolio Acquisition — On August 22, 2022, the Company, through its wholly-owned indirect subsidiary, Capistrano Portfolio Holdco LLC, acquired the Capistrano Wind Portfolio from Capistrano Wind Partners LLC, an indirect subsidiary of CEG, for a base purchase price of approximately $255 million, less working capital adjustments in the net amount of approximately $16 million, representing total net consideration of approximately $239 million. Concurrent with the acquisition, the Company also entered into a development agreement with Clearway Renew LLC, whereby Clearway Renew LLC paid $10 million to the Company at acquisition date for an exclusive right to develop, construct and repower the projects in the Capistrano Wind Portfolio, which was utilized to partially fund the acquisition of the Capistrano Wind Portfolio. The Capistrano Wind Portfolio consists of five wind projects located in Texas, Nebraska and Wyoming with a combined capacity of 413 MW that reached commercial operations between 2008 and 2012. The assets within the portfolio sell power under PPAs with investment-grade counterparties that have a weighted average remaining contract duration of approximately 10 years. The Capistrano Wind Portfolio operations are reflected in the Company’s Renewables segment and the acquisition was funded with existing sources of liquidity. The acquisition was determined to be an asset acquisition and the Company consolidates the Capistrano Wind Portfolio on a prospective basis in its financial statements. The assets and liabilities transferred to the Company relate to interests under common control by GIP and were transferred at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues , which reflects GIP’s basis. The difference between the historical cost of the Company’s net assets acquired of $250 million, less the sum of the cash paid of $239 million and the $7 million in accumulated other comprehensive income transferred to the Company, was recorded as an adjustment to CEG’s contributed capital balance. The following is a summary of assets and liabilities transferred in connection with the acquisition as of August 22, 2022: (In millions) Capistrano Wind Portfolio Other current and non-current assets (a) $ 39 Property, plant and equipment, net 147 Intangible assets for power purchase agreements 237 Right-of-use-assets, net 27 Total assets acquired 450 Long-term debt 162 Long-term lease liabilities 28 Other current and non-current liabilities 10 Total liabilities assumed 200 Net assets acquired $ 250 (a) Includes cash of $12 million and restricted cash of $4 million.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair Value Accounting under ASC 820 ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows: • Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date. • Level 2—inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. • Level 3—unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date. In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement. For cash and cash equivalents, restricted cash, accounts receivable — trade, accounts payable — trade, accounts payable — affiliates and accrued expenses and other current liabilities, the carrying amounts approximate fair value because of the short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy. The carrying amounts and estimated fair values of the Company’s recorded financial instruments not carried at fair market value or that do not approximate fair value are as follows: As of September 30, 2022 As of December 31, 2021 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Long-term debt, including current portion — affiliate $ 5 $ 5 $ 1 $ 1 Long-term debt, including current portion — external (a) 7,077 6,297 7,782 7,997 (a) Excludes net debt issuance costs, which are recorded as a reduction to long-term debt on the Company’s consolidated balance sheets. The fair value of the Company’s publicly-traded long-term debt is based on quoted market prices and is classified as Level 2 within the fair value hierarchy. The fair value of debt securities, non-publicly traded long-term debt and certain notes receivable of the Company are based on expected future cash flows discounted at market interest rates, or current interest rates for similar instruments with equivalent credit quality and are classified as Level 3 within the fair value hierarchy. The following table presents the level within the fair value hierarchy for long-term debt, including current portion as of September 30, 2022 and December 31, 2021: As of September 30, 2022 As of December 31, 2021 Level 2 Level 3 Level 2 Level 3 (In millions) Long-term debt, including current portion $ 1,757 $ 4,545 $ 2,160 $ 5,838 Recurring Fair Value Measurements The Company records its derivative assets and liabilities at fair market value on its consolidated balance sheet.

The Company uses quoted observable forward prices to value its energy contracts. To the extent that observable forward prices are not available, the quoted prices reflect the average of the forward prices from the prior year, adjusted for inflation. As of September 30, 2022, contracts valued with prices provided by models and other valuation techniques make up 100% of derivative liabilities and other financial instruments. The Company’s significant positions classified as Level 3 include physical commodity contracts executed in illiquid markets. The significant unobservable inputs used in developing fair value include illiquid power tenors and location pricing, which is derived by extrapolating pricing as a basis to liquid locations. The tenor pricing and basis spread are based on observable market data when available or derived from historic prices and forward market prices from similar observable markets when not available. The following table quantifies the significant unobservable inputs used in developing the fair value of the Company’s Level 3 positions as of September 30, 2022: September 30, 2022 Fair Value Input/Range Assets Liabilities Valuation Technique Significant Unobservable Input Low High Weighted Average (In millions) Commodity Contracts $ — $ 370 Discounted Cash Flow Forward Market Price (per MWh) $ 23.33 $ 129.06 $ 41.69 Other Financial Instruments 21 — Discounted Cash Flow Forecast annual generation levels of certain DG solar facilities 58,539 MWh 117,078 MWh 114,223 MWh The following table provides the impact on the fair value measurements to increases/(decreases) in significant unobservable inputs as of September 30, 2022: Significant Unobservable Input Position Change In Input Impact on Fair Value Measurement Forward Market Price Power Sell Increase/(Decrease) Lower/(Higher) Forecast Generation Levels Sell Increase/(Decrease) Higher/(Lower) The fair value of each contract is discounted using a risk-free interest rate. In addition, a credit reserve is applied to reflect credit risk, which is, for interest rate swaps, calculated based on credit default swaps using the bilateral method. For commodities, to the extent that the Net Exposure under a specific master agreement is an asset, the Company uses the counterparty’s default swap rate. If the Net Exposure under a specific master agreement is a liability, the Company uses a proxy of its own default swap rate. For interest rate swaps and commodities, the credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the liabilities or that a market participant would be willing to pay for the assets. As of September 30, 2022, the non-performance reserve was a $48 million gain recorded primarily to total operating revenues in the consolidated statement of income. It is possible that future market prices could vary from those used in recording assets and liabilities and such variations could be material. Concentration of Credit Risk In addition to the credit risk discussion as disclosed under Item 15 — Note 2, Summary of Significant Accounting Policies , to the consolidated financial statements included in the Company’s 2021 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company’s financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) monitoring of counterparties' credit limits on an as needed basis; (iii) as applicable, the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties. Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. A significant portion of these commodity contracts are with utilities with strong credit quality and public utility commission or other regulatory support. However, such regulated utility counterparties can be impacted by changes in government regulations or adverse financial conditions, which the Company is unable to predict. Certain subsidiaries of the Company sell the output of their facilities to PG&E, a significant counterparty of the Company, under long-term PPAs, and PG&E’s credit rating is below investment-grade.

Storm, Langford and Mesquite Sky and gains or losses are recognized in operating revenues. During the nine months ended September 30, 2022, the commodity contract for Langford, which previously met the NPNS exception, no longer qualified for NPNS treatment and, accordingly, is accounted for as a derivative and marked to fair value through operating revenues. Prior to the Thermal Disposition, which is further described in Note 3, Acquisitions and Dispositions , a portion of the Company’s derivative commodity contracts were related to its Thermal Business for the purchase of fuel/electricity commodities based on the forecasted usage of the thermal district energy centers. Realized gains and losses on these contracts were reflected in the fuel costs that were permitted to be billed to customers through the related customer contracts or tariffs and, accordingly, no gains or losses were reflected in the consolidated statements of income for these contracts through the period that the Company owned the Thermal Business. See Note 5, Fair Value of Financial Instruments , for a discussion regarding concentration of credit risk.

The tax equity bridge loan will be repaid with the final proceeds received from the tax equity investor upon Mililani I reaching substantial completion, which is expected to occur in the fourth quarter of 2022, along with the $18 million that was contributed into escrow by the tax equity investor at acquisition date. Subsequent to the Mililani I acquisition, the Company borrowed an additional $27 million in construction loans. As of September 30, 2022, the Company had $43 million in outstanding construction loans in addition to the $60 million tax equity bridge loan referenced above. Viento Funding II, LLC On March 16, 2022, the Company, through its indirect subsidiary, Viento Funding II, LLC, entered into a financing agreement which included the issuance of a $190 million term loan as well as $35 million in letters of credit, supported by the Company’s interests in the Elkhorn Ridge, Laredo Ridge, San Juan Mesa and Taloga wind projects. The term loan bears annual interest at a rate of SOFR plus a spread of 0.10% and an applicable margin, which is 1.375% per annum through the fourth anniversary of the term loan and 1.50% per annum thereafter through the maturity date of March 16, 2029. The proceeds from the term loan were used to pay off the existing debt in the amount of $186 million related to Laredo Ridge, Tapestry Wind LLC and Viento Funding II, LLC and to pay related financing costs. The Company recorded a loss on debt extinguishment of $2 million to expense unamortized debt issuance costs.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies This note should be read in conjunction with the complete description under Item 15 — Note 14, Commitments and Contingencies , to the consolidated financial statements included in the Company’s 2021 Form 10-K. The Company’s material legal proceedings are described below. The Company believes that it has valid defenses to these legal proceedings and intends to defend them vigorously. The Company records reserves for estimated losses from contingencies when information available indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. As applicable, the Company has established an adequate reserve for the matters discussed below. In addition, legal costs are expensed as incurred. Management assesses such matters based on current information and makes a judgment concerning its potential outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success. The Company is unable to predict the outcome of the legal proceedings below or reasonably estimate the scope or amount of any associated costs and potential liabilities. As additional information becomes available, management adjusts its assessment and estimates of such contingencies accordingly. Because litigation is subject to inherent uncertainties and unfavorable rulings or developments, it is possible that the ultimate resolution of the Company’s liabilities and contingencies could be at amounts that are different from its currently recorded reserves and that such difference could be material. In addition to the legal proceedings noted below, the Company and its subsidiaries are party to other litigation or legal proceedings arising in the ordinary course of business. In management’s opinion, the disposition of these ordinary course matters will not materially adversely affect the Company’s consolidated financial position, results of operations, or cash flows. Buckthorn Solar Litigation On October 8, 2019, the City of Georgetown, Texas, or Georgetown, filed a petition in the District Court of Williamson County, Texas naming Buckthorn Westex, LLC, the Company’s subsidiary that owns the Buckthorn Westex solar project, as the defendant, alleging fraud by nondisclosure and breach of contract in connection with the project and the PPA, and seeking (i) rescission and/or cancellation of the PPA, (ii) declaratory judgment that the alleged breaches constitute an event of default under the PPA entitling Georgetown to terminate, and (iii) recovery of all damages, costs of court, and attorneys’ fees. On November 15, 2019, Buckthorn Westex filed an original answer and counterclaims (i) denying Georgetown’s claims, (ii) alleging Georgetown has breached its contracts with Buckthorn Westex by failing to pay amounts due, and (iii) seeking relief in the form of (x) declaratory judgment that Georgetown’s alleged failure to pay amounts due constitute breaches of and an event of default under the PPA and that Buckthorn did not commit any events of default under the PPA, (y) recovery of costs, expenses, interest, and attorneys’ fees, and (z) such other relief to which it is entitled at law or in equity. The case is currently in discovery and is expected to proceed to trial in June 2023. Buckthorn Westex believes the allegations of Georgetown are meritless, and Buckthorn Westex is vigorously defending its rights under the PPA.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the SEC’s regulations for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the consolidated financial statements included in the Company’s 2021 Form 10-K. Interim results are not necessarily indicative of results for a full year.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amounts of net earnings during the reporting periods. Actual results could be different from these estimates.
Revenue Recognition	Revenue Recognition Revenue from Contracts with Customers The Company applies the guidance in ASC 606, Revenue from Contracts with Customers, or Topic 606, when recognizing revenue associated with its contracts with customers. The Company’s policies with respect to its various revenue streams are detailed below. In general, the Company applies the invoicing practical expedient to recognize revenue for the revenue streams detailed below, except in circumstances where the invoiced amount does not represent the value transferred to the customer. Power Purchase Agreements, or PPAs The majority of the Company’s revenues are obtained through PPAs or similar contractual agreements. Energy, capacity and where applicable, renewable attributes, from the majority of the Company’s renewable energy assets and certain conventional energy plants is sold through long-term PPAs and tolling agreements to a single counterparty, which is often a utility or commercial customer. The majority of these PPAs are accounted for as operating leases as the Company retained its historical lease assessments and classification upon adoption of ASC 842, Leases . ASC 842 requires the minimum lease payments received to be amortized over the term of the lease and contingent rentals are recorded when the achievement of the contingency becomes probable. Judgment is required by management in determining the economic life of each generating facility, in evaluating whether certain lease provisions constitute minimum payments or represent contingent rent and other factors in determining whether a contract contains a lease and whether the lease is an operating lease or capital lease. Certain of these PPAs have no minimum lease payments and all of the lease revenue under these PPAs is recorded as contingent rent on an actual basis when the electricity is delivered. Renewable Energy Credits, or RECs Renewable energy credits, or RECs, are usually sold through long-term PPAs or through REC contracts with counterparties. Revenue from the sale of self-generated RECs is recognized when the related energy is generated and simultaneously delivered even in cases where there is a certification lag as it has been deemed to be perfunctory. In a bundled contract to sell energy, capacity and/or self-generated RECs, all performance obligations are deemed to be delivered at the same time and hence, timing of recognition of revenue for all performance obligations is the same and occurs over time. In such cases, it is often unnecessary to allocate transaction price to multiple performance obligations. Thermal Revenues Steam and chilled water revenue is recognized as the Company transfers the product to the customer, based on customer usage as determined by meter readings taken at month-end. Some locations read customer meters throughout the month and recognize estimated revenue for the period between meter read date and month-end. For thermal contracts, the Company’s performance obligation to deliver steam and chilled water is satisfied over time and revenue is recognized based on the invoiced amount. The Thermal Business subsidiaries collect, and remit state and local taxes associated with sales to their customers, as required by governmental authorities. These taxes are presented on a net basis in the consolidated statements of income. As contracts for steam and chilled water are long-term contracts, the Company has performance obligations under these contracts that have not yet been satisfied. These performance obligations have transaction prices that are both fixed and variable, and that vary based on the contract duration, customer type, inception date and other contract-specific factors. For the fixed price contracts, the Company cannot accurately estimate the amount of its unsatisfied performance obligations as it will vary based on customer usage, which will depend on factors such as weather and customer activity. On May 1, 2022, the Company completed the sale of 100% of its interests in the Thermal Business to KKR. For further details of the Thermal Disposition, refer to Note 3, Acquisitions and Dispositions .
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2020, the FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments provide for optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. These amendments apply only to contracts that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform, which affects certain of the Company’s debt and interest rate swap agreements. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. As of September 30, 2022, the Company has applied the amendments to all of its eligible contract modifications, where applicable, during the reference rate reform period. Additionally, the Company has not elected any optional expedients provided in the standard.
Concentration of Credit Risk	Concentration of Credit Risk In addition to the credit risk discussion as disclosed under Item 15 — Note 2, Summary of Significant Accounting Policies , to the consolidated financial statements included in the Company’s 2021 Form 10-K, the following item is a discussion of the concentration of credit risk for the Company’s financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) monitoring of counterparties' credit limits on an as needed basis; (iii) as applicable, the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties. Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. A significant portion of these commodity contracts are with utilities with strong credit quality and public utility commission or other regulatory support. However, such regulated utility counterparties can be impacted by changes in government regulations or adverse financial conditions, which the Company is unable to predict. Certain subsidiaries of the Company sell the output of their facilities to PG&E, a significant counterparty of the Company, under long-term PPAs, and PG&E’s credit rating is below investment-grade.
