Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Clearway Energy, Inc., together with its consolidated subsidiaries, or the Company, is a publicly-traded energy infrastructure investor in and owner of modern, sustainable and long-term contracted assets across North America. The Company is sponsored by GIP III Zephyr Acquisition Partners, L.P. through its portfolio company, CEG. GIP is an independent fund manager that invests in infrastructure assets in energy and transport sectors. The Company’s environmentally-sound asset portfolio includes over 6,201 MW of wind, solar and natural gas-fired power generation facilities. Through this diversified and contracted portfolio, the Company endeavors to provide its investors with stable and growing dividend income. Nearly all of these assets sell substantially all of their output pursuant to long-term offtake agreements with creditworthy counterparties. The weighted average remaining contract duration of these offtake agreements was approximately 13 years as of September 30, 2020 based on CAFD. The Company also owns thermal infrastructure assets with an aggregate steam and chilled water capacity of 1,456 net MWt and electric generation capacity of 39 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. The Company consolidates the results of Clearway Energy LLC through its controlling interest, with CEG's interest shown as noncontrolling interest in the financial statements. The holders of the Company's outstanding shares of Class A and Class C common stock are entitled to dividends as declared. CEG receives its distributions from Clearway Energy LLC through its ownership of Clearway Energy LLC Class B and Class D units. As a result of the Class C common stock issuance under the ATM Programs during the nine months ended September 30, 2020, the Company owns 57.58% of the economic interests of Clearway Energy LLC, with CEG retaining 42.42% of the economic interests of Clearway Energy LLC as of September 30, 2020. For further discussion, see Note 9, Changes in Capital Structure. The following table represents the structure of the Company as of September 30, 2020: 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 2019 Form 10-K. Interim results are not necessarily indicative of results for a full year. In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary to present fairly the Company's consolidated financial position as of September 30, 2020, and the results of operations, comprehensive income (loss) and cash flows for the nine months ended September 30, 2020 and 2019. PG&E Bankruptcy Update On July 1, 2020, PG&E emerged from bankruptcy and assumed the Company's contracts without modification. In addition, PG&E paid to the Company's applicable projects the portion of the invoices corresponding to the electricity delivered for the period between January 1 and January 28, 2019. These invoices related to the pre-petition period services and any payment therefore required the approval by the Bankruptcy Court. During the three months ended September 30, 2020, the Company entered into waiver agreements with the lenders to the respective financing agreements related to the PG&E Bankruptcy and all previously restricted distributions were paid out of distribution reserve accounts at the Company's subsidiaries affected by the PG&E Bankruptcy as of October 31, 2020. A description of changes to the financial statements resulting from PG&E's emergence from bankruptcy is noted below in Note 2, Summary of Significant Accounting Policies , Note 5, Fair Value of Financial Instruments and Note 7, Long-term Debt .

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, and the reported amounts of revenues and expenses during the reporting period. Actual results could be different from these estimates. Cash and 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 $176 million and $125 million as of September 30, 2020 and December 31, 2019, respectively. During October 2020, the last of the previously restricted cash of $34 million was paid out of a distribution reserve account at a subsidiary affected by the PG&E Bankruptcy to Clearway Energy Operating LLC. 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 statements of cash flows: September 30, 2020 December 31, 2019 (In millions) Cash and cash equivalents $ 359 $ 155 Restricted cash 178 262 Cash, cash equivalents and restricted cash shown in the statement of cash flows $ 537 $ 417 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, 2020, these restricted funds were comprised of $74 million designated to fund operating expenses, approximately $46 million designated for current debt service payments, and $28 million restricted for reserves including debt service, performance obligations and other reserves, as well as capital expenditures. The remaining $30 million is held in distribution reserve accounts.

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. 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 income statement. 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 which 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. Power Purchase Agreements The majority of the Company’s revenues are obtained through PPAs or other 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 leases. Previously ASC 840, and currently 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. Management's judgment is required 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 sales-type lease. Renewable Energy Credits Renewable energy credits, or RECs, are usually sold through long-term PPAs. 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. Disaggregated Revenues The following tables represent the Company’s disaggregation of revenue from contracts with customers along with the reportable segment for each category for the three and nine months ended September 30, 2020 and 2019 respectively: Three months ended September 30, 2020 (In millions) Conventional Generation Renewables Thermal Total Energy revenue (a) $ 3 $ 166 $ 27 $ 196 Capacity revenue (a) 119 — 24 143 Contract amortization (6) (15) (1) (22) Other revenue — 6 9 15 Total operating revenue 116 157 59 332 Less: Lease revenue (122) (153) — (275) Less: Contract amortization 6 15 1 22 Total revenue from contracts with customers $ — $ 19 $ 60 $ 79 (a) The following amounts of energy and capacity revenue relate to leases and are accounted for under ASC 842: (In millions) Conventional Generation Renewables Thermal Total Energy revenue $ 3 $ 153 $ — $ 156 Capacity revenue 119 — — 119 Total $ 122 $ 153 $ — $ 275 Nine months ended September 30, 2020 (In millions) Conventional Generation Renewables Thermal Total Energy revenue (a) $ 6 $ 486 $ 77 $ 569 Capacity revenue (a) 338 — 50 388 Contract amortization (18) (46) (2) (66) Other revenue — 12 24 36 Mark-to-market for economic hedges — (8) — (8) Total operating revenue 326 444 149 919 Less: Mark-to-market for economic hedges — 8 — 8 Less: Lease revenue (344) (449) (1) (794) Less: Contract amortization 18 46 2 66 Total revenue from contracts with customers $ — $ 49 $ 150 $ 199 (a) The following amounts of energy and capacity revenue relate to leases and are accounted for under ASC 842: (In millions) Conventional Generation Renewables Thermal Total Energy revenue $ 6 $ 449 $ 1 $ 456 Capacity revenue 338 — — 338 Total $ 344 $ 449 $ 1 $ 794 Three months ended September 30, 2019 (In millions) Conventional Generation Renewables Thermal Total Energy revenue (a) $ 2 $ 167 $ 33 $ 202 Capacity revenue (a) 89 — 14 103 Contract amortization (1) (16) (1) (18) Mark-to-market for economic hedges — (2) — (2) Other revenue — 2 9 11 Total operating revenue 90 151 55 296 Less: Mark-to-market for economic hedges — 2 — 2 Less: Lease revenue (91) (160) (1) (252) Less: Contract amortization 1 16 1 18 Total revenue from contracts with customers $ — $ 9 $ 55 $ 64 (a) The following amounts of energy and capacity revenue relate to leases and are accounted for under ASC 842: (In millions) Conventional Generation Renewables Thermal Total Energy revenue $ 2 $ 160 $ 1 $ 163 Capacity revenue 89 — — 89 Total $ 91 $ 160 $ 1 $ 252 Nine months ended September 30, 2019 (In millions) Conventional Generation Renewables Thermal Total Energy revenue (a) $ 4 $ 441 $ 91 $ 536 Capacity revenue (a) 253 — 41 294 Contract amortization (4) (46) (2) (52) Mark-to-market for economic hedges — (9) — (9) Other revenue — 6 22 28 Total operating revenue 253 392 152 797 Less: Mark-to-market for economic hedges — 9 — 9 Less: Lease revenue (257) (416) (2) (675) Less: Contract amortization 4 46 2 52 Total revenue from contracts with customers $ — $ 31 $ 152 $ 183 (a) The following amounts of energy and capacity revenue relate to leases and are accounted for under ASC 842: (In millions) Conventional Generation Renewables Thermal Total Energy revenue $ 4 $ 416 $ 2 $ 422 Capacity revenue 253 — — 253 Total $ 257 $ 416 $ 2 $ 675 Contract Amortization Assets and liabilities recognized from power sales agreements assumed through acquisitions related to the sale of electric capacity and energy in future periods for which the fair value has been determined to be significantly less (more) than market are amortized to revenue over the term of each underlying contract based on actual generation and/or contracted volumes or on a straight-line basis, where applicable.

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 is met. These amendments apply only to contracts that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company intends to apply the amendments to all its eligible contract modifications where applicable. Recently Issued Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The guidance is effective January 1, 2021, with early adoption permitted. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements. Reclassification Certain prior year amounts have been reclassified for comparative purposes.

Equity Method Investments and Joint Ventures [Abstract]
Investments Accounted for by the Equity Method and Variable Interest Entities	Investments Accounted for by the Equity Method and Variable Interest Entities Entities that are Consolidated The Company has a controlling financial interest in certain entities which have been identified as VIEs under ASC 810, Consolidations, or ASC 810. These arrangements are primarily related to tax equity arrangements entered into with third parties in order to monetize certain tax credits associated with wind and solar facilities, as further described in Note 5, Investments Accounted for by the Equity Method and Variable Interest Entities, to the consolidated financial statements included in the Company's 2019 Form 10-K. Summarized financial information for the Company's consolidated VIEs consisted of the following as of September 30, 2020: (In millions) Oahu Solar Partnership Kawailoa Partnership Elbow Creek TE Holdco Wildorado TE Holdco DGPV Holdco 3 Alta TE Holdco Spring Canyon Buckthorn Renewables LLC Other (a) Other current and non-current assets $ 25 $ 24 $ 10 $ 16 $ 61 $ 58 $ 3 $ 3 $ 5 Property, plant and equipment 182 142 102 244 329 363 82 209 8 Intangible assets — — 1 — 1 228 — — — Total assets 207 166 113 260 391 649 85 212 13 Current and non-current liabilities 125 116 27 12 276 44 5 7 3 Total liabilities 125 116 27 12 276 44 5 7 3 Noncontrolling interest 25 35 74 107 3 38 29 62 — Net assets less noncontrolling interests $ 57 $ 15 $ 12 $ 141 $ 112 $ 567 $ 51 $ 143 $ 10 (a) Other is comprised of Crosswinds and Hardin projects. The discussion below describes material changes to VIEs during the nine months ended September 30, 2020. DGPV Holdco 3 LLC DGPV Holdco 3 owns approximately 113 MW of distributed solar capacity, based on cash to be distributed, with a weighted average remaining contract life of approximately 21 years as of September 30, 2020. On May 29, 2020, the final construction projects for DGPV Holdco 3 were placed in service which resulted in a reconsideration event for consolidation of the entity. Upon the reconsideration event, the Company determined that it was the primary beneficiary of DGPV Holdco 3, as it is entitled to 99% of allocations of income and cash distributions from the entity. As such, effective on May 29, 2020, the Company consolidates DGPV Holdco 3, and shows the interest owned by CEG as noncontrolling interest. DGPV Holdco 3 owns an interest in two tax equity funds with tax equity investors, both of which are consolidated by DGPV Holdco 3, and the interests owned by the tax equity investors are shown as noncontrolling interests. The Company removed its investment in DGPV Holdco 3 of $155 million as of May 29, 2020 and recorded the difference between the net assets consolidated and the investment balance as a reduction to noncontrolling interests. The following table shows the balances that were consolidated effective on May 29, 2020: (In millions) May 29, 2020 Current assets $ 32 Property, plant and equipment 331 Intangible assets 1 Other non-current assets 37 Total assets $ 401 Debt 206 Other current and non-current liabilities 84 Total liabilities $ 290 Noncontrolling interests and redeemable noncontrolling interests 6 Net assets less noncontrolling interests $ 105 Prior to the reconsideration event described above, the Company invested $10 million of cash in DGPV Holdco 3 during the first half of 2020. DGPV Holdco Consolidation On November 2, 2020, the Company acquired the Class B membership interests in DGPV Holdco 1, DGPV Holdco 2 and DGPV Holdco 3, or DGPV Holdco Entities, from Renew DG Holdings LLC, a subsidiary of CEG, and an SREC contract for $44 million in cash consideration. The Company previously held the Class A membership interests in the DGPV Holdco Entities and accounted for its interests in DGPV Holdco 1 and DGPV Holdco 2 as equity method investments, while DGPV Holdco 3 was consolidated by the Company effective May 29, 2020 as described above. As further described in Note 7, Long-term Debt , subsequent to the acquisition of the remaining interests in the DGPV Holdco Entities, the Company transferred its interests to DG-CS Master Borrower LLC, and issued debt that was utilized to repay existing project-level debt outstanding and unwind interest rate swaps for certain of the tax equity arrangements related to the underlying project funds. Effective with the acquisition of the Class B membership interests of the DGPV Holdco Entities, the Company consolidates all of the DGPV Holdco Entities, including DG-CS Master Borrower LLC, and its subsidiaries, which consist of seven tax equity funds that collectively own approximately 172 distributed solar projects with a combined 286 MW of capacity. Each of the tax equity funds is a VIE, where the Company is the primary beneficiary and consolidates the fund, with the tax equity investor's interest shown as noncontrolling interest or redeemable noncontrolling interest. The acquired SREC contract, a contract to receive incremental cash flows related to renewable energy credits from certain of the underlying solar projects, will be considered a derivative financial instrument. Repowering Partnership II LLC On May 11, 2020, the Company acquired CEG's interest in Repowering Partnership II LLC, for cash consideration of $70 million. Repowering Partnership II LLC is no longer a VIE and subsequent to the acquisition, is a wholly-owned subsidiary of the Company. Repowering Partnership II LLC continues to own interests in two VIEs, Wildorado Repowering Tax Equity Holdco LLC, or Wildorado TE Holdco, and Elbow Creek Repowering Tax Equity Holdco LLC, or Elbow Creek TE Holdco. The Company removed the related noncontrolling interest balance of $8 million and recorded the difference between the cash paid and the noncontrolling interest balance removed as a reduction to noncontrolling interests. On February 7, 2020, a third party tax equity investor purchased 100% of the Class A membership interests in Wildorado TE Holdco, for $148 million. In addition, the Company contributed $112 million to Wildorado TE Holdco. The combined proceeds were used to repay construction debt under the Repowering Partnership Holdco credit agreement, as described in Note 7, Long-term Debt . The third party tax equity investor, or Wildorado Investor, will receive 99% of allocations of taxable income and other items until the Wildorado Investor obtains a specified return on its initial investment, or the last day of the PTC period, whichever occurs sooner. At such time, the allocations to the Wildorado Investor will change to 5%. Until such time, the Wildorado Investor will receive a variable percentage of cash distributions. Wildorado TE Holdco is a VIE and the Repowering Partnership II LLC is the primary beneficiary through its position as managing member. As a result, the Company consolidates Wildorado TE Holdco, with the Wildorado Investor's interest shown as noncontrolling interest. In connection with the Wildorado TE Holdco closing, the allocations of income at Repowering Partnership II LLC changed to 60.14% for Wind TE Holdco LLC (the Company member) and 39.86% for CWSP Wildorado Elbow Holding LLC (the CEG member). As noted above, CEG no longer has an interest in Repowering Partnership II LLC as of June 30, 2020. The Company utilizes the HLBV method to determine the net income or loss allocated to tax equity noncontrolling interest. The Company recorded a de minimis loss and a loss of $36 million attributable to the noncontrolling interest of Wildorado TE Holdco for the three and nine months ending September 30, 2020 and recorded a loss of $1 million and $9 million attributable to the noncontrolling interest of Elbow Creek TE Holdco for the three and nine months ending September 30, 2020, respectively. Entities that are not Consolidated The Company has interests in entities that are considered VIEs under ASC 810, but for which it is not considered the primary beneficiary. The Company accounts for its interests in these entities under the equity method of accounting, as further described in Note 5, Investments Accounted for by the Equity Method and Variable Interest Entities , to the consolidated financial statements included in the Company's 2019 Form 10-K. Mesquite Star Pledgor LLC On September 1, 2020, the Company, through its indirect subsidiary Mesquite Star HoldCo LLC, acquired the Class A membership interests in Mesquite Star Pledgor LLC from Clearway Renew LLC, a subsidiary of CEG, for $79 million in cash consideration. Mesquite Star Pledgor LLC is the primary beneficiary and consolidates its interest in a tax equity fund that owns the Mesquite Star wind project, a 419 MW utility scale wind project located in Fisher County, Texas. A majority of the project’s output is backed by contracts with investment grade counterparties with a 12 year weighted average contract life. The transaction is reflected in the Company's Renewables segment and was funded with cash on hand. Mesquite Star Pledgor LLC is a VIE and the Company is not the primary beneficiary. Accordingly, the Company recorded the acquired interest as an equity method investment. The membership interests acquired by the Company relate to interests under common control by GIP and were recorded at historical cost. The difference between the $79 million cash paid and the historical value of the Company's acquired interests of $83 million was recorded as an adjustment to noncontrolling interest. The Company's maximum exposure to loss as of September 30, 2020 is limited to its equity investment in the unconsolidated entities, as further summarized in the table below: Name Economic Interest Investment Balance (In millions) Utah Solar Portfolio (a) 50% $ 268 Desert Sunlight 25% 257 Agua Caliente Solar 16% 89 GenConn 50% 90 DGPV Holdco 1 LLC (a) 95% 81 DGPV Holdco 2 LLC (a) 95% 63 San Juan Mesa 75% 42 Elkhorn Ridge 66.7% 39 Avenal 50% (5) Mesquite Star (a) 50% 77 $ 1,001 ( a ) VIEs and tax equity structures and economic interest are based on cash to be distributed The following tables present summarized financial information for the Company's significant equity method investments: Three months ended September 30, Nine months ended September 30, (In millions) 2020 2019 2020 2019 Income Statement Data: DGPV Holdco 3 (a) Operating revenue $ — $ 9 $ 14 $ 22 Operating income — 6 6 11 Net income (loss) $ — $ 16 $ (12) $ 24 ( a) Year to date as of the reconsideration event on May 29, 2020 (In millions) As of September 30, 2020 As of December 31, 2019 Balance Sheet Data: DGPV Holdco 3 (a) Current assets $ — $ 39 Non-current assets — 371 Current liabilities — 61 Non-current liabilities — 216 Redeemable noncontrolling interest $ — $ (1) (a) DGPV Holdco 3 was no longer an equity method investment as of the reconsideration event on May 29, 2020

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, accounts receivable - affiliate, accounts payable, accounts payable - affiliate, accrued expenses and other 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 estimated carrying amounts and fair values of the Company’s recorded financial instruments not carried at fair market value are as follows: As of September 30, 2020 As of December 31, 2019 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Long-term debt, including current portion (a) $ 6,797 $ 6,873 $ 6,858 $ 6,957 (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 non-publicly traded long-term debt 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, 2020 and December 31, 2019: As of September 30, 2020 As of December 31, 2019 Level 2 Level 3 Level 2 Level 3 (In millions) Long-term debt, including current portion $ 1,874 $ 4,999 $ 1,736 $ 5,221 Recurring Fair Value Measurements The Company records its derivative assets and liabilities at fair value on its consolidated balance sheet. The following table presents assets and liabilities measured and recorded at fair value on the Company's consolidated balance sheets on a recurring basis and their level within the fair value hierarchy: As of September 30, 2020 As of December 31, 2019 Fair Value (a) Fair Value (a) (In millions) Level 2 Level 3 Level 2 Level 3 Derivative liabilities: Commodity contracts $ — $ 17 $ — $ 9 Interest rate contracts 169 — 83 — Total liabilities $ 169 $ 17 $ 83 $ 9 (a) There were no derivative assets classified as Level 1, Level 2 or Level 3 and no liabilities classified as Level 1 as of September 30, 2020 and as of December 31, 2019. The following table reconciles the beginning and ending balances for instruments that are recognized at fair value in the condensed consolidated financial statements using significant unobservable inputs: Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 (In millions) Fair Value Measurement Using Significant Unobservable Inputs (Level 3) Fair Value Measurement Using Significant Unobservable Inputs (Level 3) Beginning balance $ (17) $ (7) $ (9) $ — Total losses for the period included in earnings — (2) (8) (2) Purchases — — — (7) Ending balance $ (17) $ (9) $ (17) $ (9) Change in unrealized losses included in earnings for derivatives held as of September 30, 2020 $ — $ 8 Derivative Fair Value Measurements The Company's contracts are non-exchange-traded and valued using prices provided by external sources. For some of the Company’s energy contracts, management receives quotes from multiple sources. To the extent that multiple quotes are received, the prices reflect the average of the bid-ask mid-point prices obtained from all sources believed to provide the most liquid market for the commodity. The remainder of the assets and liabilities represent contracts for which external sources or observable market quotes are not available. These contracts are valued based on various valuation techniques including, but not limited to, internal models based on a fundamental analysis of the market and extrapolation of the observable market data with similar characteristics. As of September 30, 2020, contracts valued with prices provided by models and other valuation techniques make up 9% of derivative liabilities. The Company’s significant position classified as Level 3 includes physical power 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 and 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 tables quantify the significant unobservable inputs used in developing the fair value of the Company's Level 3 positions as of September 30, 2020: September 30, 2020 Fair Value Input/Range Assets Liabilities Valuation Technique Significant Unobservable Input Low High Weighted Average (In millions) Power Contracts $ — $ (17) Discounted Cash Flow Forward Market Price (per MWh) 9.21 37.46 16.32 The following table provides sensitivity of fair value measurements to increases/(decreases) in significant unobservable inputs as of September 30, 2020: Significant Observable Input Position Change In Input Impact on Fair Value Measurement Forward Market Price Power Buy Increase/(Decrease) Higher/(Lower) Forward Market Price Power Sell Increase/(Decrease) Lower/(Higher) 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, 2020, the non-performance reserve was a $10 million gain recorded primarily in interest expense in the consolidated statements of operations. 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 in Note 2, Summary of Significant Accounting Policies , to the consolidated financial statements included in the Company's 2019 Form 10-K, the following 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; (iii) 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. The majority of these power 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.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies This note should be read in conjunction with the complete description under Item 15 — Note 17, Commitments and Contingencies , to the Company's 2019 Form 10-K. Contingencies 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. Nebraska Public Power District Litigation On January 11, 2019, Nebraska Public Power District, or NPPD, sent written notice to certain of the Company’s subsidiaries which own the Laredo Ridge and Elkhorn Ridge wind projects alleging an event of default under each of the PPAs between NPPD and the projects. NPPD alleges that the Company moved forward with certain transactions without obtaining the consent of NPPD. NPPD threatened to terminate the applicable PPAs by February 11, 2019 if the alleged default was not cured. The Company filed a motion for a temporary restraining order and preliminary injunction in the U.S. District Court for the District of Nebraska relating to the Laredo Ridge project, and a similar motion in the District Court of Knox County, Nebraska for the Elkhorn Ridge project, to enjoin NPPD from taking any actions related to the PPAs. On February 19, 2019, the U.S. District Court in the Laredo Ridge matter approved a stipulation between the parties to provide for an injunction preventing NPPD from terminating the PPA pending disposition of the litigation. On February 26, 2019, the Knox County District Court approved a similar stipulation relating to the Elkhorn Ridge project. On April 13, 2020, the U.S. District Court granted the wind projects' motion for summary judgment and permanently enjoined NPPD from terminating the PPAs in reliance on the alleged events of default. The U.S. District Court decision was appealed by NPPD on May 11, 2020 and the case in the Knox County District Court remains pending, but has been stayed pending the outcome of the U.S. District Court case. The Company believes the allegations of NPPD are meritless and the Company is vigorously defending its rights under the PPAs. 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. Buckthorn Westex believes the allegations of Georgetown are meritless, and Buckthorn Westex is vigorously defending its rights under the PPA.

Leases [Abstract]
Leases	Leases Accounting for Leases The Company evaluates each arrangement at inception to determine if it contains a lease. All of the Company’s leases are operating leases as of September 30, 2020. Lessee The Company records its operating lease liabilities at the present value at lease commencement date of the lease payments over the lease term. Lease payments include fixed payment amounts, as well as variable rate payments based on an index initially measured at lease commencement date. Variable payments, including payments based on future performance and based on index changes, are recorded as the expense is incurred. The Company determines the relevant lease term by evaluating whether renewal and termination options are reasonably to certain to be exercised. The Company uses its incremental borrowing rate to calculate the present value of the lease payments, based on information available at the lease commencement date. The Company’s leases consist of land leases for numerous operating asset locations, real estate leases and equipment leases. The terms and conditions for these leases vary by the type of underlying asset. Lease expense was comprised of the following: Three months ended September 30, 2020 Three months ended September 30, 2019 Nine months ended September 30, 2020 Nine months ended September 30, 2019 (In millions) Operating lease cost - Fixed $ 5 $ 2 $ 14 $ 6 Operating lease cost - Variable 2 3 7 10 Total lease cost $ 7 $ 5 $ 21 $ 16 The Company lease liabilities as of September 30, 2020 and December 31, 2019 comprised of the following: September 30, 2020 December 31, 2019 (In millions, except term and rate) ROU Assets - operating leases, net $ 256 $ 223 Short-term lease liability - operating leases (a) 7 7 Long-term lease liability - operating leases 260 227 Total lease liability $ 267 $ 234 Weighted average remaining lease term 24 25 Weighted average discount rate 4.3 % 4.4 % Nine months ended September 30, 2020 Nine months ended September 30, 2019 Cash paid for operating leases $ 13 $ 7 (a) Short-term lease liability balances are included within the accrued expenses and other current liabilities line item of the consolidated balance sheets as of September 30, 2020 and December 31, 2019.

These leases are comprised of both fixed payments and variable payments contingent upon volumes or performance metrics. The terms of the leases are further described in Item 2 — MD&A, Introduction, Environmental, Regulatory of this Form 10-Q. Many of the leases have renewal options at the end of the lease term. Termination may be allowed under specific circumstances in the lease arrangements, such as under an event of default. All but one of the Company’s leases are operating leases. The remaining lease met the criteria of a s ales-type lease and the impact of this sales-type lease to the consolidated financial statements was immaterial.

Goodwill and Intangible Assets Disclosure [Abstract]
Asset Impairments	Asset ImpairmentsThe Company recorded an impairment loss of $19 million related to a facility in the Thermal segment during the second quarter of 2019. The fair value of the facility was determined using an income approach by applying a discounted cash flow methodology to the long-term budgets for each respective plant. The income approach utilized estimates of discounted future cash flows, which were Level 3 fair value measurement and include key inputs, such as forecasted power prices, operations and maintenance expense, and discount rates. The Company measured the impairment loss as the difference between the carrying amount and the fair value of the assets.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
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, and the reported amounts of revenues and expenses during the reporting period. 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. 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 income statement. 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 which 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. Power Purchase Agreements The majority of the Company’s revenues are obtained through PPAs or other 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 leases. Previously ASC 840, and currently 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. Management's judgment is required 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 sales-type lease. Renewable Energy Credits Renewable energy credits, or RECs, are usually sold through long-term PPAs. 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. Contract Amortization Assets and liabilities recognized from power sales agreements assumed through acquisitions related to the sale of electric capacity and energy in future periods for which the fair value has been determined to be significantly less (more) than market are amortized to revenue over the term of each underlying contract based on actual generation and/or contracted volumes or on a straight-line basis, where applicable.
Recently Issued Accounting Standards Not Yet Adopted	Recently Issued Accounting Standards Adopted in 2020 In March 2020, the FASB issued ASU 2020-4, 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 is met. These amendments apply only to contracts that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company intends to apply the amendments to all its eligible contract modifications where applicable. Recently Issued Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The guidance is effective January 1, 2021, with early adoption permitted. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements.
Reclassification	Reclassification Certain prior year amounts have been reclassified for comparative purposes.
Segment Reporting	The Company’s segment structure reflects how management currently operates and allocates resources. The Company's businesses are segregated based on conventional power generation, renewable businesses which consist of solar and wind, and the thermal and chilled water business. The Corporate segment reflects the Company's corporate costs. The Company's chief operating decision maker, its Chief Executive Officer, evaluates the performance of its segments based on operational measures including adjusted earnings before interest, taxes, depreciation and amortization, or Adjusted EBITDA, and CAFD, as well as economic gross margin and net income (loss).
