Note 1 — Nature of Business

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

The Company was previously owned by NRG Energy, Inc., or NRG. On August 31, 2018, NRG transferred its full ownership interest in the Company to CEG, the holder of NRG's renewable energy development and operations platform, and subsequently sold 100% of its interest in CEG to GIP, referred to hereinafter as the GIP Transaction.

The Company’s environmentally-sound asset portfolio includes over 5,272 MW of wind, solar and natural gas-fired power generation facilities, as well as district energy systems. Through this diversified and contracted portfolio, the Company endeavors to provide its investors with stable and growing dividend income.Substantially all of the Company's generation assets are under long-term contractual arrangements for the output or capacity from these assets. The thermal assets are comprised of district energy systems and combined heat and power plants that produce steam, hot water and/or chilled water and, in some instances, electricity at a central plant. Certain district energy systems are subject to rate regulation by state public utility commissions (although they may negotiate certain rates) while the other district energy systems have rates determined by negotiated bilateral contracts. For the complete listing of the company's generation assets, refer to Item 2 - MD&A, Introduction, Environmental, Regulatory to this Form 10-Q.

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 Clearway Energy, Inc.'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. Clearway Energy, Inc. currently owns 55.8% of the economic interests of Clearway Energy LLC, with CEG retaining 44.2% of the economic interests of Clearway Energy LLC.

The following table represents the structure of the Company as of March 31, 2019:

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 2018 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 March 31, 2019 , and the results of operations, comprehensive income (loss) and cash flows for the three months ended March 31, 2019 and 2018.

PG&E Bankruptcy

On January 29, 2019, 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. Certain subsidiaries of the Company, 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 PPAs. The Company consolidates three of the solar facilities and Marsh Landing, and records its interest in the other solar facilities as equity method investments. As of March 31, 2019, the Company had $1.4 billion of property, plant and equipment, net, $352 million investments in unconsolidated affiliates and $1.3 billion of borrowings with final maturity dates ranging from 2023 - 2038 related to these facilities. The related subsidiaries of the Company 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 financing agreements, and as a result, the Company recorded $1.3 billion of principal, net of the related unamortized debt issuance costs, as short-term debt as of March 31, 2019. As of May 6, 2019, PG&E has neither assumed,

13

rejected, nor sought to renegotiate any of its contracts with the Company. The Company is actively seeking forbearance agreements with non-recourse project level lenders for each respective financing arrangement. For further discussion see Note 7, Long-term Debt.

Transition Services Agreement

As a result of the GIP Transaction, the Company entered into a Transition Services Agreement with NRG, or the NRG TSA, pursuant to which NRG or certain of its affiliates began providing certain services to the Company following the consummation of the GIP Transaction on August 31, 2018, in exchange for the payment of a fee in respect of such services. The agreement is effective until the earlier of June 30, 2019 or the date that all services are terminated by the Company. The Company may extend the term on a month-by-month basis no later than March 31, 2020 for a fixed monthly fee provided for in the agreement. Expenses related to the NRG TSA are recorded in transaction and integration costs in the consolidated statements of operations.

Note 2 — 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 $80 million and $109 million as of March 31, 2019 and December 31, 2018, 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 statements of cash flows.

	March 31,		December 31,
	2019		2018
	(in millions)
Cash and cash equivalents	$	115	$	407
Restricted cash	181		176
Cash, cash equivalents and restricted cash shown in the statement of cash flows	$	296	$	583

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 March 31, 2019, these restricted funds were comprised of $57 million designated to fund operating expenses, approximately $43 million designated for current debt service payments, and $39 million restricted for reserves including debt service, performance obligations and other reserves, as well as capital expenditures. The remaining $42 million is held in distributions reserve accounts, of which $36 million related to subsidiaries affected by the PG&E Bankruptcy as discussed in Note 1, Nature of Business, and may not be distributed during the pendency of the bankruptcy.

Accumulated Depreciation, Accumulated Amortization

The following table presents the accumulated depreciation included in the property, plant and equipment, net, and accumulated amortization included in intangible assets, net, respectively, as of March 31, 2019 and December 31, 2018:

	March 31, 2019		December 31, 2018
	(In millions)
Property, Plant and Equipment Accumulated Depreciation	$	1,674	$	1,590
Intangible Assets Accumulated Amortization	325		308

Revenue Recognition

Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance in ASC 606, Revenue from Contracts with Customers, orTopic 606, using the modified retrospective method applied to contracts which were not completed as of the adoption date, with no adjustment required to the financial statements upon adoption. Following the adoption of the new standard, the Company’s revenue recognition of its contracts with customers remains materially consistent with its historical practice. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. 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 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.

Power Purchase Agreements, or PPAs

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. ASC 840 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 capital lease.

15

Renewable Energy Credits, or RECs

As stated above, 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.

Sale of Emission Allowances

The Company records its bank of emission allowances as part of intangible assets. From time to time, management may authorize the transfer of emission allowances in excess of usage from the Company's emission bank to intangible assets held-for-sale for trading purposes. The Company records the sale of emission allowances on a net basis within operating revenue in the Company's consolidated statements of operations.

Disaggregated Revenues

The following tables represent the Company’s disaggregation of revenue from contracts with customers along with the reportable segment for each category:

	Three months ended March 31, 2019

Note 3 — Business Acquisitions

2018 Acquisitions

UPMC Thermal Project Asset Acquisition— On June 19, 2018, upon reaching substantial completion, the Company acquired from NRG the UPMC Thermal Project for cash consideration of $84 million, subject to working capital adjustments. The Company had a payable of $4 million to NRG as of December 31, 2018, $3 million of which was paid in January 2019 upon final completion of the project pursuant to the EPC agreement. The project added 73 MWt of thermal equivalent capacity and 7.5 MW of emergency backup thermal capacity to the Company's portfolio. The transaction is reflected in the Company's Thermal segment. The acquisition was funded with the proceeds from the sale of the Series E Notes and Series F Notes. The assets transferred to the Company relate to interests under common control by NRG and were recorded at book value in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the purchase price and book value of the assets was recorded as a distribution to NRG and decreased the balance of contributed capital. The acquisition was determined to be an asset acquisition and not a business combination, and therefore no recast of the historical financial information was deemed necessary.

17

Central CA Fuel Cell 1, LLC — On April 18, 2018, the Company acquired the Central CA Fuel Cell 1, LLC project in Tulare, California from FuelCell Energy Finance, Inc., for cash consideration of $11 million, subject to working capital adjustments. The project adds 2.8 MW of thermal capacity to the Company's portfolio, with a 20-year PPA contract with the City of Tulare. The transaction is reflected in the Company's Thermal segment.

Buckthorn Solar Drop Down Asset — On March 30, 2018, the Company acquired 100% of NRG's interests in Buckthorn Renewables, LLC, which owned a 154 MW construction-stage utility-scale solar generation project located in Texas, or the Buckthorn Solar Drop Down Asset, for cash consideration of $42 million. The Company also assumed non-recourse debt of $183 million and non-controlling interest of $19 million, as of the acquisition date, attributable to the Class A member. The Company converted $132 million of non-recourse debt to a term loan and the remainder of the outstanding debt was paid down with the contribution from the Class A member in the amount of $80 million upon the project reaching substantial completion in May 2018. The purchase price for the Buckthorn Solar Drop Down Asset was funded with cash on hand and borrowings from the Company's revolving credit facility. The assets and liabilities transferred to the Company related to interests under common control by NRG and were recorded at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the cash paid and historical value of the entities' equity was recorded as a distribution to NRG and decreased the balance of contributed capital. Since the transaction constituted a transfer of net assets under common control, the guidance requires retrospective combination of the entities for all periods presented as if the combination had been in effect since the inception of common control.

The project sells power under a 25-year PPA to the City of Georgetown, Texas, which commenced in July 2018.

Note 4 — 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 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 2018 Form 10-K.

Oahu Partnership — On August 31, 2018, the Company entered into an agreement with Clearway Renew, a subsidiary of CEG, to acquire the Class A membership interests in the Zephyr Oahu Partnership LLC, or Oahu Partnership, for $20 million in cash consideration. The purpose of the partnership is to own, finance, operate, and maintain the Oahu Solar projects, which consist of Lanikuhana and Waipio, utility-scale solar generation projects which represent 15 MW and 46 MW respectively, the indirect subsidiaries of the Oahu Partnership, which are being developed in Oahu, Hawaii. The Oahu Solar projects are contracted to sell power under long-term PPAs with Hawaiian Electric Company, Inc.

On March 8, 2019, the Company made an initial capital contribution in the amount of $4 million, which represents 20% of its total anticipated capital contributions. The Company also assumed non-recourse debt in the amount of $143 million, as further described in Note 7 — Long-term Debt and a non-controlling interest in the amount of $18 million attributable to a tax equity investor's initial contribution. The Company also recorded a payable in the amount of $16 million due to Clearway Renew in accounts payable — affiliate on the Company's consolidated balance sheets as of March 31, 2019. The payable represents the remaining 80% of the equity commitment and will be funded on the date the Oahu Solar LLC projects reaches substantial completion. The Company, as a Class A member, is the primary beneficiary through its position as managing member and consolidates Oahu Partnership. Allocations of income and taxable items are equal to the distributions of available cash, which is currently 95% to the Company and 5% to Clearway Renew.

The Company's acquisition of the Class A membership interests in the Oahu Partnership was accounted for as a transfer of assets under common control and was recorded at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the cash paid and payable recorded and the historical value of the assets was recorded as a contribution from CEG and increased the balance of its noncontrolling interest.

Repowering Partnership LLC — On August 30, 2018, Wind TE Holdco, an indirect subsidiary of the Company, entered into a partnership with Clearway Renew LLC, an indirect subsidiary of CEG, in order to facilitate the repowering of wind facilities of two of its indirect subsidiaries, Elbow Creek Wind Project LLC and Wildorado Wind LLC. Wind TE Holdco contributed its interests in the two facilities and Clearway Renew LLC contributed a turbine supply agreement, including title to certain components that qualify for production tax credits. Wind TE Holdco is the managing member of Repowering Partnership LLC and consolidates the entity, which is a VIE. Clearway Renew LLC is entitled to allocations of 21% of income, which is reflected in Wind TE Holdco’s noncontrolling interests.

18

Wind TE Holdco Buyout — On January 2, 2019, the Company bought out 100% of the Class A membership interests from the tax equity investor of Wind TE Holdco, for cash consideration of $19 million. The Company recorded the difference between the value of the interest bought and the cash received to equity and allocated it between non-controlling interest and additional paid in capital based on the economic ownership interest between CEG and public interest as of January 2, 2019.

Buckthorn Renewables, LLC — As described in Note 3, Business Acquisitions, on March 30, 2018, the Company acquired 100% of NRG’s interest in a 154 MW construction-stage utility-scale solar generation project, Buckthorn Renewables, LLC, which owns 100% interest in Buckthorn Solar Portfolio, LLC, which in turn owns 100% of the Class B membership interests in Buckthorn Holdings, LLC. Buckthorn Holdings, LLC is a tax equity fund, which is a variable interest entity that is consolidated by Buckthorn Solar Portfolio, LLC. The Company is the primary beneficiary, through its position as managing member, and indirectly consolidates Buckthorn Holdings, LLC through Buckthorn Solar Portfolio, LLC. The Class A member's interest in the tax equity fund is reflected as noncontrolling interest on the Company’s consolidated balance sheet. The Company utilizes the HLBV method to determine the net income or loss allocated to the tax equity investor noncontrolling interest.

Summarized financial information for the Company's consolidated VIEs consisted of the following as of March 31, 2019:

The Company owns approximately 59 MW of distributed solar capacity, based on cash to be distributed, with a weighted average remaining contract life of approximately 21 years as of March 31, 2019.

Note 5 — 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 payable, accounts payable — affiliates, 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 March 31, 2019				As of December 31, 2018
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
(In millions)
Liabilities:
Long-term debt — affiliate, including current portion	44		42		259		257
Long-term debt — external, including current portion (a)	$	5,842	$	5,825	$	5,779	$	5,681

^(a) Excludes deferred financing 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 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 March 31, 2019 and December 31, 2018:

	As of March 31, 2019				As of December 31, 2018
	Level 2		Level 3		Level 2		Level 3
	(In millions)
Long-term debt, including current portion	$	1,474	$	4,393	$	1,358	$	4,580

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 March 31, 2019						As of December 31, 2018
	Fair Value (a)						Fair Value (a)
(In millions)	Level 2		Level 3		Total		Level 2
Derivative assets:
Interest rate contracts	$	1	$	—	$	1	$	11
Total assets	1		—		1		11
Derivative liabilities:
Commodity contracts	—		7		7		—
Interest rate contracts	35		—		35		21
Total liabilities	$	35	$	7	$	42	$	21

^(a) There were no derivative assets or liabilities classified as Level 1 as of March 31, 2019, and no derivative assets or liabilities classified as Level 1 or Level 3 as of December 31, 2018.

The following table reconciles, for the three months ended March 31, 2019, the beginning and ending balances for instruments that are recognized at fair value in the condensed consolidated financial statements using significant unobservable inputs:

(In millions)	Fair Value Measurement Using Significant Unobservable Inputs (Level 3)
Beginning balance as of January 1, 2019	$	—
Purchases	(7		)
Ending balance as of March 31, 2019	$	(7	)

There were no gains or losses for the period included in earnings attributable to the change in unrealized gains or losses relating to assets or liabilities still held as of March 31, 2019.

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 March 31, 2019, contracts valued with prices provided by models and other valuation techniques make up 17% 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 March 31, 2019:

21

	March 31, 2019
	Fair Value						Input/Range
	Assets		Liabilities		Valuation Technique	Significant Unobservable Input	Low	High	Weighted Average
(In millions)
Power Contracts	$	—	$	7	Discounted Cash Flow	Forward Market Price (per MWh)	5	55	15

The following table provides sensitivity of fair value measurements to increases/(decreases) in significant unobservable inputs as of March 31, 2019:

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 March 31, 2019, the non-performance reserve was $2 million gain in cost of operations and interest expense. 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 2018 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, which the Company is unable to predict.

On January 29, 2019, PG&E filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Certain subsidiaries of the Company sell the output of their facilities to PG&E under long-term PPAs, including interests in 6 solar facilities totaling 480 MW and Marsh Landing with a capacity of 720 MW. The Company consolidates three of the solar facilities and Marsh Landing and records its interest in the other solar facilities as equity method investments. The Company had $17 million in accounts receivable due from PG&E for its consolidated projects, of which $5 million was reclassified to non-current assets as of March 31, 2019.

Impact of Derivative Instruments on the Statements of Operations

The Company has interest rate derivative instruments that are not designated as cash flow hedges. The effect of interest rate hedges is recorded to interest expense. For the three months ended March 31, 2019 and 2018, the impact to the consolidated statements of operations was a loss of $18 million and a gain of $24 million, respectively.

A portion of the Company’s derivative commodity contracts relates to its Thermal Business for the purchase of fuel commodities based on the forecasted usage of the thermal district energy centers. Realized gains and losses on these contracts are reflected in the fuel costs that are permitted to be billed to customers through the related customer contracts or tariffs and, accordingly, no gains or losses are reflected in the consolidated statements of operations for these contracts. During the three months ended March 31, 2019, Elbow Creek entered into a new long term power hedge, and the impact to the consolidated statements of operations was a $7 million loss for the period.

See Note 5, Fair Value of Financial Instruments, for a discussion regarding concentration of credit risk.

Note 11 — Contingencies

This note should be read in conjunction with the complete description under Note 14, Commitments and Contingencies, to the Company's 2018 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 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. The Company believes the allegations of NPPD are meritless and the Company is vigorously defending its rights under the PPAs.

Note 12— Leases

Adoption of Topic 842

The Company adopted ASU No. 2019-01, Leases (Topic 842), or Topic 842, on January 1, 2019 using the modified retrospective transition method and therefore, prior period financial information has not been adjusted and continues to be reflected in accordance with the Company’s historical accounting policy. Topic 842 requires the establishment of a lease liability and related right-of-use, or ROU, asset for all leases with a term longer than 12 months. The Company elected certain of the permitted practical expedients, including the expedient that permits the Company to retain its existing lease assessment and classification. The Company also elected to account for lease and non-lease components for specific asset classes as a single lease component.

The adoption of the standard resulted in the recording of operating lease liabilities of $174 million and related ROU assets of $168 million. There was no impact to the Company’s consolidated statement of operations or cash flows. The Company utilized its incremental borrowing rate at adoption date, ranging from 4.04% - 4.67%, to determine the amount of the lease liabilities.

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 March 31, 2019.

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 for the three months ended March 31, 2019 was comprised of the following:

(In millions)
Operating lease cost	$	2
Variable lease cost	4
Total lease cost	$	6

Operating lease information as of March 31, 2019 was as follows:

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 of the Company’s leases are operating leases. Certain of these leases have both lease and non-lease components, and the Company allocates the transaction price to the components based on standalone selling prices. As disclosed in Note 2, Summary of Significant Accounting Policies, the following amounts of energy and capacity revenue are related to the Company’s leases:

(In millions)	Conventional Generation		Renewables		Total

Significant Events

Pacific Gas and Electric Company Bankruptcy

• On January 29, 2019, 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.  Certain subsidiaries of the Company, 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 PPAs.  The Company consolidates three of the solar facilities and Marsh Landing and records its interest in the other solar facilities as equity method investments. As of March 31, 2019, the Company had $1.4 billion of property, plant and equipment, net, $352 million investments in unconsolidated affiliates and $1.3 billion of borrowings with final maturity dates ranging from 2023 - 2038 related to these facilities. The related subsidiaries of the Company 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 has triggered defaults under the PPAs with PG&E and such related financing agreements, as further discussed in Item 1 —Note 7, Long-Term Debt. As a result, the Company recorded approximately $1.3 billion of principal, net of the related unamortized debt issuance costs, with final maturity dates ranging from 2023 - 2038, as short-term debt. The Company continues to assess the potential future impacts of the PG&E bankruptcy filing as events occur.

Repayment of 2019 Convertible Notes

• In January 2019, Clearway Energy, Inc. repurchased an aggregate principal amount of $50 million of the 2019 Convertible Notes in open market transactions. The repurchases were funded through a partial repayment of the intercompany note between Clearway Operating LLC and Clearway Energy, Inc. The 2019 Convertible Notes matured on February 1, 2019 and the Company paid off the remaining balance of an aggregate principal amount of $170 million.

Carlsbad Project

• On February 6, 2018, the Company entered into an agreement with NRG to purchase 100% of the membership interests in Carlsbad Energy Holdings LLC, which indirectly owns the Carlsbad project, a 527 MW natural gas fired project in Carlsbad, CA, pursuant to the NRG ROFO Agreement. Following the COD of the project in December 2018, the Company elected to utilize the Carlsbad backstop facility provided by GIP; as such, GIP purchased 100% of the membership interest in Carlsbad Energy Holdings LLC on February 27, 2019. The purchase price for the transaction was $387 million in cash consideration, exclusive of working capital and other adjustments, as well as the assumption of non-recourse debt of $601 million at completion. The Company maintains the option to purchase Carlsbad from GIP at any time within 18 months after February 27, 2019 at the same economic terms at which it originally agreed to purchase the asset from NRG. Should the Company not acquire Carlsbad during such 18 months, the project will become a CEG ROFO Asset.

Distribution Reduction

• On February 12, 2019, and as a result of impacts related to the PG&E Bankruptcy, Clearway Energy, Inc.'s Board of Directors declared a quarterly dividend on its Class A and Class C common stock of $0.20 per share paid on March 15, 2019, to stockholders of record as of March 1, 2019. This dividend was reduced from the prior quarterly dividend paid in December 2018 of $0.331 per share. A similar decrease was made to the Company's distributions to its unitholders. Again on May 1, 2019, the Company's Board of Directors declared a quarterly dividend on Class A and Class C common stock of $0.20 per share, payable on June 15, 2019 to stockholders of record as of June 1, 2019. The Company will continue to assess the level of the distribution pending developments in the PG&E Bankruptcy, including the Company’s ability to receive unrestricted project distributions.

CEG ROFO Agreement Amendment

• On February 14, 2019, the CEG ROFO Agreement was amended to grant the Company a right of first offer for Hawaii Solar Phase II, which consists of the Mililani I and Waiawa solar and storage projects located in Oahu, Hawaii.

The purchase price for the Hawaii Solar Phase I ROFO Acquisition projects will be funded with existing liquidity. The projects are expected to be completed in summer 2019.

Wind TE Holdco Buyout

• On August 30, 2018, Wind TE Holdco entered into a partnership with CEG in order to facilitate the repowering of the Elbow Creek and Wildorado facilities. As part of the repowering partnership, the Company bought out an existing tax equity partner of Wind TE Holdco for $19 million on January 2, 2019. For further discussion, see Note 4, Investments Accounted for by the Equity Method and Variable Interest Entities.

Duquesne Thermal

• On May 1, 2019, the Company, through its indirect subsidiary ECP Uptown Campus LLC, acquired the Duquesne University district energy system, totaling 87 combined MWt, located in Pittsburgh, PA. The total investment for the project, including capital expenditures required to interconnect the project to the Company's existing system, is approximately $107 million. In connection with the transaction, ECP Uptown Campus LLC issued non-recourse project debt of $95 million. The Company used proceeds from debt, in combination with cash on hand to purchase the project from the University. As part of the acquisition, Duquesne University entered into a 40-year Energy Services Agreement through which ECP Uptown Campus LLC will fulfill the university’s electricity, chilled water and steam requirements in exchange for monthly capacity payments.

Management’s Discussion of the Results of Operations for the Three Months Ended March 31, 2019 and 2018

Gross Margin

The Company calculates gross margin in order to evaluate operating performance as operating revenues less cost of sales, which includes cost of fuel, contract and emission credit amortization and mark-to-market for economic hedging activities.

Economic Gross Margin

In addition to gross margin, the Company evaluates its operating performance using the measure of economic gross margin, which is not a GAAP measure and may not be comparable to other companies’ presentations or deemed more useful than the GAAP information provided elsewhere in this report.  Economic gross margin should be viewed as a supplement to and not a substitute for the Company's presentation of gross margin, which is the most directly comparable GAAP measure.  Economic gross margin is not intended to represent gross margin. The Company believes that economic gross margin is useful to investors as it is a key operational measure reviewed by the Company's chief operating decision maker. Economic gross margin is defined as energy and capacity revenue less cost of fuels. Economic gross margin excludes the following components from GAAP gross margin: contract amortization, mark-to-market results, emissions credit amortization and (losses) gains on economic hedging activities. Mark-to-market results consist of unrealized gains and losses on contracts that are not yet settled.

The below tables present the composition of gross margin, as well as the reconciliation to economic gross margin, for the three months ended March 31, 2019 and 2018:

(In millions)	Conventional Generation			Renewables			Thermal			Total
Three months ended March 31, 2019
Energy and capacity revenues	$	80		$	108		$	45		$	233
Other revenues	—			2			6			8

Gross margin decreased by $7 million during the three months ended March 31, 2019, compared to the same period in 2018 primarily due to a combination of the following:

Segment	Increase (Decrease)			Reason for Increase
(In millions)
Renewables:	$	(10	)	$7 million mark-to-market loss on the Elbow Creek forward power sale contract entered into during the first quarter of 2019, as well as a decrease of $3 million due to lower wind and solar resources, partially offset by revenue generated at the Buckthorn Solar facility which went COD in July 2018
Thermal:	2			Revenues generated at the UPMC Thermal Project, which was completed in the second quarter of 2018
Conventional:	1			Fewer outages in 2019 compared to 2018
	$	(7	)

Operations and Maintenance

Operations and maintenance expense decreased by $5 million during the three months ended March 31, 2019, compared to the same period in 2018, primarily due to reduced outages and general maintenance costs at El Segundo and Walnut Creek projects of the Conventional segment.

Development Costs

The Company incurred $1 million of development cost expense during the three months ended March 31, 2019, which primarily related to business development, personnel and benefits costs within the Company's Thermal segment.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates decreased by $1 million during the three months ended March 31, 2019, compared to the same period in 2018, primarily driven by lower income allocated to the Company's interests in DGPV Holdco entities partially offset by higher income allocated to the Company's interests in the Utah Solar Portfolio.

Interest Expense

Interest expense increased by $49 million during the three months ended March 31, 2019, compared to the same period in 2018, primarily due to the following:

(In millions)	Increase (Decrease)
Change in fair value of interest rate swaps	$	44
Issuance of Energy Center Minneapolis Series E, F, G, H Notes in June 2018 and additional interest expense for the Buckthorn Solar project-level debt	4
Issuance of the 2025 Senior Notes in October 2018, partially offset by lower interest expense due to lower outstanding balances on Clearway Energy Operating LLC's intercompany notes with Clearway Energy, Inc.	5
Normal amortization for project-level debt	(4		)
	$	49

Income Attributable to Noncontrolling Interests

For the three months ended March 31, 2019, the Company had a loss of $2 million attributable to CEG's economic interest in Repowering Partnership LLC and a loss of $4 million attributable to noncontrolling interests with respect to its tax equity financing arrangements and the application of the HLBV method. For the three months ended March 31, 2018, the Company had a loss of $37 million attributable to noncontrolling interests with respect to its tax equity financing arrangements and application of the HLBV method, which generally allocates more loss to the noncontrolling interest in the first several years after fund formation, reflecting the allocation of tax items such as production tax credits and tax depreciation to the fund investors.

52

Liquidity and Capital Resources

The Company's principal liquidity requirements are to meet its financial commitments, finance current operations, fund capital expenditures, including acquisitions from time to time, service debt and pay distributions. As a normal part of the Company's business, depending on market conditions, the Company will from time to time consider opportunities to repay, redeem, repurchase or refinance its indebtedness. Changes in the Company's operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause the Company to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions.

Liquidity Position

As of March 31, 2019, the Company had $454 million of available borrowings under its revolving credit facility. As of March 31, 2019 and December 31, 2018, the Company's liquidity was $750 million and $1,037 million, respectively, comprised of the following:

(In millions)	March 31, 2019		December 31, 2018
Cash and cash equivalents:
Clearway Energy LLC, excluding subsidiaries	$	35	$	298
Subsidiaries	80		109
Restricted cash:
Operating accounts	57		84
Reserves, including debt service, distributions, performance obligations and other reserves	124		92
Total cash, cash equivalents and restricted cash	$	296	$	583
Revolving credit facility availability	454		454
Total liquidity	$	750	$	1,037

The Company's liquidity includes $181 million and $176 million of restricted cash balances as of March 31, 2019 and December 31, 2018, respectively. Restricted cash consists primarily of funds to satisfy the requirements of certain debt arrangements and funds held within the Company's projects that are restricted in their use. As of March 31, 2019, these restricted funds were comprised of $57 million designated to fund operating expenses, $43 million designated for current debt service payments, and $39 million restricted for reserves including debt service, performance obligations and other reserves, as well as capital expenditures. The remaining $42 million is held in distribution reserve accounts, of which $36 million related to subsidiaries affected by the PG&E Bankruptcy as discussed further below and may not be distributed during the pendency of the PG&E Bankruptcy.

As of March 31, 2019, there were no outstanding borrowings and $41 million of letters of credit outstanding under the Company's revolving credit facility.

On January 29, 2019, PG&E filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code. The PG&E Bankruptcy had no effect on availability under the Company’s revolving credit facility. However, the Company has non-recourse project-level debt related to each of its subsidiaries that sell their output to PG&E under long-term PPAs. The PG&E Bankruptcy triggered defaults under the related financing agreements which caused uncertainty around the timing of when certain project-level cash distributions will be available to the Company.  As of March 31, 2019, all project level cash balances for these subsidiaries were classified as restricted cash.

Management believes that the Company's liquidity position, cash flows from operations and availability under its revolving credit facility will be adequate to meet the Company's financial commitments; debt service obligations; growth, operating and maintenance capital expenditures; and to fund distributions to Clearway Energy, Inc. and CEG.  Management continues to regularly monitor the Company's ability to finance the needs of its operating, financing and investing activity within the dictates of prudent balance sheet management.

Credit Ratings

Credit rating agencies rate a firm's public debt securities. These ratings are utilized by the debt markets in evaluating a firm's credit risk. Ratings influence the price paid to issue new debt securities by indicating to the market the Company's ability to pay principal, interest and preferred dividends. Rating agencies evaluate a firm's industry, cash flow, leverage, liquidity, and hedge profile, among other factors, in their credit analysis of a firm's credit risk.

53

The following table summarizes the credit ratings for the Company and its Senior Notes as of March 31, 2019:

	S&P	Moody's
Clearway Energy, Inc.	BB	Ba2
5.375% Senior Notes, due 2024	BB	Ba2
5.750% Senior Notes, due 2025	BB	Ba2
5.000% Senior Notes, due 2026	BB	Ba2

Sources of Liquidity

The Company's principal sources of liquidity include cash on hand, cash generated from operations, borrowings under new and existing financing arrangements and the issuance of additional equity and debt securities as appropriate given market conditions. As described inItem 1— Note 7, Long-term Debt, to this Form 10-Q and Note 10, Long-term Debt, to the consolidated financial statements included in the Company's 2018 Form 10-K, the Company's financing arrangements consist of corporate level debt, which includes Senior Notes, 2020 Convertible Notes, and the revolving credit facility; the ATM Program; and project-level financings for its various assets.

ATM Sales — Clearway Energy, Inc. did not sell any shares of Class C common stockduring the three months ended March 31, 2019. As of March 31, 2019, approximately $36 million of Class C common stock remains available for issuance under the ATM Program.

Uses of Liquidity

The Company's requirements for liquidity and capital resources, other than for operating its facilities, are categorized as: (i) debt service obligations, as described more fully in Item 1 — Note 7, Long-term Debt; (ii) capital expenditures; (iii) acquisitions and investments; and (iv) distributions.

Capital Expenditures

The Company's capital spending program is mainly focused on maintenance capital expenditures, consisting of costs to maintain the assets currently operating, such as costs to replace or refurbish assets, and growth capital expenditures consisting of costs to construct new assets, costs to complete the construction of assets where construction is in process, and capital expenditures related to acquiring additional thermal customers. For the three months ended March 31, 2019, the Company used approximately $16 million to fund capital expenditures, including growth expenditures of $12 million, primarily in the Renewables segment in connection with the Oahu Partnership entered by the Company on March 8, 2019, and to a lesser extent in the Thermal segment in connection with the Mylan development project. For the three months ended March 31, 2018, the Company used approximately $18 million to fund capital expenditures, of which$10 million related to growth expenditures in the Renewables segment paid by NRG in connection with the construction of Buckthorn Solar. The Company develops annual capital spending plans based on projected requirements for maintenance and growth capital. The Company estimates $30 million of maintenance expenditures for 2019. These estimates are subject to continuing review and adjustment and actual capital expenditures may vary from these estimates.

Acquisitions and Investments

The Company intends to acquire generation assets developed and constructed by CEG, as well as generation and thermal infrastructure assets from third parties, where the Company believes its knowledge of the market and operating expertise provides a competitive advantage, and to utilize such acquisitions as a means to grow its CAFD. 

Wind TE Holdco Buyout — On January 2, 2019, the Company bought out 100% of Class A membership interest from the TE Investor, for cash consideration of $19 million, as further described in Item 1 — Note 4, Investments Accounted for by the Equity Method and Variable Interest Entities.

OahuPartnership — On March 8, 2019,the Company entered into a partnership with Clearway Renew LLC, a subsidiary of CEG, to own, finance, operate, and maintain the Oahu Solar projects, which consist of Lanikuhana and Waipio, utility-scale solar generation projects which represent 15 MW and 46 MW respectively, in Oahu, Hawaii. The Company made an original capital contribution in the amount of $4 million and recorded a payable in the amount of $16 million due to Clearway Renew in accounts payable — affiliate on the Company's consolidated balance sheets as of March 31, 2019. For further discussion, see Note 4, Investments Accounted for by the Equity Method and Variable Interest Entities.

54

Duquesne Thermal — On May 1, 2019, the Company, through its indirect subsidiary ECP Uptown Campus LLC, acquired the Duquesne University district energy system, totaling 87 combined MWt, located in Pittsburgh, PA. The total investment for the project, including capital expenditures required to interconnect the project to the Company's existing system, is approximately $107 million. In connection with the transaction, ECP Uptown Campus LLC issued non-recourse project debt of $95 million. The Company used proceeds from debt, in combination with cash on hand to purchase the project from the University. As part of the acquisition, Duquesne University entered into a 40-year Energy Services Agreement through which ECP Uptown Campus LLC will fulfill the university’s electricity, chilled water and steam requirements in exchange for monthly capacity payments.

Investment Partnership with CEG

During the three months ended March 31, 2019, the Company invested $4 million in distributed generation partnerships with CEG.

Open Market Repurchases

In January 2019, Clearway Energy, Inc. repurchased an aggregate principal amount of $50 million of the 2019 Convertible Notes in open market transactions. The repurchases were funded through a partial repayment of the intercompany note between Clearway Operating LLC and Clearway Energy, Inc.

Cash Distributions to Clearway Energy, Inc. and CEG

The Company intends to distribute to its unit holders in the form of a quarterly distribution all of the CAFD it generates each quarter, less reserves for the prudent conduct of the business, including among others, maintenance capital expenditures to maintain the operating capacity of the assets. Distributions on the units are subject to available capital, market conditions, and compliance with associated laws, regulations and other contractual obligations. The Company expects that, based on current circumstances, comparable cash distributions will continue to be paid in the foreseeable future. The Company will continue to evaluate its capital allocation approach during the pendency of the PG&E Bankruptcy, including the Company’s ability to receive unrestricted project distributions.

The following table lists the distributions paid on the Company's Class A, B, C and D units during the three months ended March 31, 2019:

Off-Balance Sheet Arrangements

Obligations under Certain Guarantee Contracts

The Company may enter into guarantee arrangements in the normal course of business to facilitate commercial transactions with third parties.

Retained or Contingent Interests

The Company does not have any material retained or contingent interests in assets transferred to an unconsolidated entity.

Obligations Arising Out of a Variable Interest in an Unconsolidated Entity

Variable interest in equity investments — As of March 31, 2019, the Company has several investments with an ownership interest percentage of 50% or less in energy and energy-related entities that are accounted for under the equity method. Utah Solar Portfolio, GenConn, DGPV Holdco 1, RPV Holdco, DGPV Holdco 2, and DGPV Holdco 3 are variable interest entities for which the Company is not the primary beneficiary.

The Company's pro-rata share of non-recourse debt held by unconsolidated affiliates was approximately $926 million as of March 31, 2019. This indebtedness may restrict the ability of these subsidiaries to issue dividends or distributions to the Company.

Contractual Obligations and Commercial Commitments

The Company has a variety of contractual obligations and other commercial commitments that represent prospective cash requirements in addition to the Company's capital expenditure programs, as disclosed in the Company's 2018 Form 10-K. See also Note 3, Business Acquisitions to this Form 10-Q for a discussion of additional contingencies that occurred during 2018.

Fair Value of Derivative Instruments

The Company may enter into fuel purchase contracts and other energy-related derivative instruments to mitigate variability in earnings due to fluctuations in spot market prices and to hedge fuel requirements at certain generation facilities. In addition, in order to mitigate interest rate risk associated with the issuance of variable rate debt, the Company enters into interest rate swap agreements.

The tables below disclose the activities of non-exchange traded contracts accounted for at fair value in accordance with ASC 820. Specifically, these tables disaggregate realized and unrealized changes in fair value; disaggregate estimated fair values at March 31, 2019, based on their level within the fair value hierarchy defined in ASC 820; and indicate the maturities of contracts at March 31, 2019.

The Company has elected to disclose derivative assets and liabilities on a trade-by-trade basis and does not offset amounts at the counterparty master agreement level. As discussed below in Quantitative and Qualitative Disclosures about Market Risk - Commodity Price Risk, NRG, on behalf of the Company, measures the sensitivity of the portfolio to potential changes in market prices using VaR, a statistical model which attempts to predict risk of loss based on market price and volatility. NRG's risk management policy places a limit on one-day holding period VaR, which limits the net open position.

Critical Accounting Policies and Estimates

The Company's discussion and analysis of the financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements and related disclosures in compliance with GAAP requires the application of appropriate technical accounting rules and guidance as well as the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. The application of these policies necessarily involves judgments regarding future events, including the likelihood of success of particular projects, legal and regulatory challenges, and the fair value of certain assets and liabilities. These judgments, in and of themselves, could materially affect the financial statements and disclosures based on varying assumptions, which may be appropriate to use. In addition, the financial and operating environment may also have a significant effect, not only on the operation of the business, but on the results reported through the application of accounting measures used in preparing the financial statements and related disclosures, even if the nature of the accounting policies has not changed.

On an ongoing basis, the Company evaluates these estimates, utilizing historic experience, consultation with experts and other methods the Company considers reasonable. In any event, actual results may differ substantially from the Company's estimates. Any effects on the Company's business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the information that gives rise to the revision becomes known.

The Company identifies its most critical accounting policies as those that are the most pervasive and important to the portrayal of the Company's financial position and results of operations, and that require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain. The Company's critical accounting policies include income taxes and valuation allowance for deferred tax assets, impairment of long lived assets and other intangible assets and acquisition accounting.

ITEM 4 — Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure ControlsandProcedures

Under the supervision and with the participation of the Company's management, including its principal executive officer, principal financial officer and principal accounting officer, the Company conducted an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures, as such term is defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act. Based on this evaluation, the Company's principal executive officer, principal financial officer and principal accounting officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

In connection with the GIP Transaction, the Company entered into a TSA pursuant to which NRG Energy, Inc. provided information technology, systems, applications, and business processes to the Company.  Under the TSA with NRG Energy, Inc., the Company continues to review, document and evaluate the internal controls over financial reporting through March 31, 2019. There were no changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended March 31, 2019 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Nature of Business Disclosure [Abstract]

Nature of Business

Nature of Business

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

The Company was previously owned by NRG Energy, Inc., or NRG. On August 31, 2018, NRG transferred its full ownership interest in the Company to CEG, the holder of NRG's renewable energy development and operations platform, and subsequently sold 100% of its interest in CEG to GIP, referred to hereinafter as the GIP Transaction.

The Company’s environmentally-sound asset portfolio includes over 5,272 MW of wind, solar and natural gas-fired power generation facilities, as well as district energy systems. Through this diversified and contracted portfolio, the Company endeavors to provide its investors with stable and growing dividend income.Substantially all of the Company's generation assets are under long-term contractual arrangements for the output or capacity from these assets. The thermal assets are comprised of district energy systems and combined heat and power plants that produce steam, hot water and/or chilled water and, in some instances, electricity at a central plant. Certain district energy systems are subject to rate regulation by state public utility commissions (although they may negotiate certain rates) while the other district energy systems have rates determined by negotiated bilateral contracts. For the complete listing of the company's generation assets, refer to Item 2 - MD&A, Introduction, Environmental, Regulatory to this Form 10-Q.

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 Clearway Energy, Inc.'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. Clearway Energy, Inc. currently owns 55.8% of the economic interests of Clearway Energy LLC, with CEG retaining 44.2% of the economic interests of Clearway Energy LLC.

The following table represents the structure of the Company as of March 31, 2019:

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 2018 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 March 31, 2019 , and the results of operations, comprehensive income (loss) and cash flows for the three months ended March 31, 2019 and 2018.

PG&E Bankruptcy

On January 29, 2019, 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. Certain subsidiaries of the Company, 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 PPAs. The Company consolidates three of the solar facilities and Marsh Landing, and records its interest in the other solar facilities as equity method investments. As of March 31, 2019, the Company had $1.4 billion of property, plant and equipment, net, $352 million investments in unconsolidated affiliates and $1.3 billion of borrowings with final maturity dates ranging from 2023 - 2038 related to these facilities. The related subsidiaries of the Company 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 financing agreements, and as a result, the Company recorded $1.3 billion of principal, net of the related unamortized debt issuance costs, as short-term debt as of March 31, 2019. As of May 6, 2019, PG&E has neither assumed, rejected, nor sought to renegotiate any of its contracts with the Company. The Company is actively seeking forbearance agreements with non-recourse project level lenders for each respective financing arrangement. For further discussion see Note 7, Long-term Debt.

Transition Services Agreement

As a result of the GIP Transaction, the Company entered into a Transition Services Agreement with NRG, or the NRG TSA, pursuant to which NRG or certain of its affiliates began providing certain services to the Company following the consummation of the GIP Transaction on August 31, 2018, in exchange for the payment of a fee in respect of such services. The agreement is effective until the earlier of June 30, 2019 or the date that all services are terminated by the Company. The Company may extend the term on a month-by-month basis no later than March 31, 2020 for a fixed monthly fee provided for in the agreement. Expenses related to the NRG TSA are recorded in transaction and integration costs in the consolidated statements of operations.

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 $80 million and $109 million as of March 31, 2019 and December 31, 2018, 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 statements of cash flows.

	March 31,		December 31,
	2019		2018
	(in millions)
Cash and cash equivalents	$	115	$	407
Restricted cash	181		176
Cash, cash equivalents and restricted cash shown in the statement of cash flows	$	296	$	583

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 March 31, 2019, these restricted funds were comprised of $57 million designated to fund operating expenses, approximately $43 million designated for current debt service payments, and $39 million restricted for reserves including debt service, performance obligations and other reserves, as well as capital expenditures. The remaining $42 million is held in distributions reserve accounts, of which $36 million related to subsidiaries affected by the PG&E Bankruptcy as discussed in Note 1, Nature of Business, and may not be distributed during the pendency of the bankruptcy.

Accumulated Depreciation, Accumulated Amortization

The following table presents the accumulated depreciation included in the property, plant and equipment, net, and accumulated amortization included in intangible assets, net, respectively, as of March 31, 2019 and December 31, 2018:

	March 31, 2019		December 31, 2018
	(In millions)
Property, Plant and Equipment Accumulated Depreciation	$	1,674	$	1,590
Intangible Assets Accumulated Amortization	325		308

Noncontrolling Interests

Noncontrolling interests represent the equity associated with CEG's interest in Repowering Partnership LLC, as described in Note 4, Investments Accounted for by the Equity Method and Variable Interest Entities, and third-party interests in the net assets under certain tax equity arrangements, which are consolidated by the Company, that have been entered into to finance the cost of wind facilities eligible for tax credits.

Distributions

The following table lists the distributions paid on Clearway Energy LLC's Class A, B, C and D units during the three months ended March 31, 2019:

	First Quarter 2019
Distributions per Class A, B, C and D unit	$	0.20

On May 1, 2019, Clearway Energy LLC declared a distribution on its Class A, Class B, Class C and Class D units of $0.20 per unit payable on June 17, 2019 to unit holders of record as of June 3, 2019.

Revenue Recognition

Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance in ASC 606, Revenue from Contracts with Customers, orTopic 606, using the modified retrospective method applied to contracts which were not completed as of the adoption date, with no adjustment required to the financial statements upon adoption. Following the adoption of the new standard, the Company’s revenue recognition of its contracts with customers remains materially consistent with its historical practice. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. 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 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.

Power Purchase Agreements, or PPAs

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. ASC 840 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 capital lease.

Renewable Energy Credits, or RECs

As stated above, 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.

Sale of Emission Allowances

The Company records its bank of emission allowances as part of intangible assets. From time to time, management may authorize the transfer of emission allowances in excess of usage from the Company's emission bank to intangible assets held-for-sale for trading purposes. The Company records the sale of emission allowances on a net basis within operating revenue in the Company's consolidated statements of operations.

Disaggregated Revenues

The following tables represent the Company’s disaggregation of revenue from contracts with customers along with the reportable segment for each category:

Business Acquisitions

2018 Acquisitions

UPMC Thermal Project Asset Acquisition— On June 19, 2018, upon reaching substantial completion, the Company acquired from NRG the UPMC Thermal Project for cash consideration of $84 million, subject to working capital adjustments. The Company had a payable of $4 million to NRG as of December 31, 2018, $3 million of which was paid in January 2019 upon final completion of the project pursuant to the EPC agreement. The project added 73 MWt of thermal equivalent capacity and 7.5 MW of emergency backup thermal capacity to the Company's portfolio. The transaction is reflected in the Company's Thermal segment. The acquisition was funded with the proceeds from the sale of the Series E Notes and Series F Notes. The assets transferred to the Company relate to interests under common control by NRG and were recorded at book value in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the purchase price and book value of the assets was recorded as a distribution to NRG and decreased the balance of contributed capital. The acquisition was determined to be an asset acquisition and not a business combination, and therefore no recast of the historical financial information was deemed necessary.

Central CA Fuel Cell 1, LLC — On April 18, 2018, the Company acquired the Central CA Fuel Cell 1, LLC project in Tulare, California from FuelCell Energy Finance, Inc., for cash consideration of $11 million, subject to working capital adjustments. The project adds 2.8 MW of thermal capacity to the Company's portfolio, with a 20-year PPA contract with the City of Tulare. The transaction is reflected in the Company's Thermal segment.

Buckthorn Solar Drop Down Asset — On March 30, 2018, the Company acquired 100% of NRG's interests in Buckthorn Renewables, LLC, which owned a 154 MW construction-stage utility-scale solar generation project located in Texas, or the Buckthorn Solar Drop Down Asset, for cash consideration of $42 million. The Company also assumed non-recourse debt of $183 million and non-controlling interest of $19 million, as of the acquisition date, attributable to the Class A member. The Company converted $132 million of non-recourse debt to a term loan and the remainder of the outstanding debt was paid down with the contribution from the Class A member in the amount of $80 million upon the project reaching substantial completion in May 2018. The purchase price for the Buckthorn Solar Drop Down Asset was funded with cash on hand and borrowings from the Company's revolving credit facility. The assets and liabilities transferred to the Company related to interests under common control by NRG and were recorded at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the cash paid and historical value of the entities' equity was recorded as a distribution to NRG and decreased the balance of contributed capital. Since the transaction constituted a transfer of net assets under common control, the guidance requires retrospective combination of the entities for all periods presented as if the combination had been in effect since the inception of common control.

The project sells power under a 25-year PPA to the City of Georgetown, Texas, which commenced in July 2018.

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 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 2018 Form 10-K.

Oahu Partnership — On August 31, 2018, the Company entered into an agreement with Clearway Renew, a subsidiary of CEG, to acquire the Class A membership interests in the Zephyr Oahu Partnership LLC, or Oahu Partnership, for $20 million in cash consideration. The purpose of the partnership is to own, finance, operate, and maintain the Oahu Solar projects, which consist of Lanikuhana and Waipio, utility-scale solar generation projects which represent 15 MW and 46 MW respectively, the indirect subsidiaries of the Oahu Partnership, which are being developed in Oahu, Hawaii. The Oahu Solar projects are contracted to sell power under long-term PPAs with Hawaiian Electric Company, Inc.

On March 8, 2019, the Company made an initial capital contribution in the amount of $4 million, which represents 20% of its total anticipated capital contributions. The Company also assumed non-recourse debt in the amount of $143 million, as further described in Note 7 — Long-term Debt and a non-controlling interest in the amount of $18 million attributable to a tax equity investor's initial contribution. The Company also recorded a payable in the amount of $16 million due to Clearway Renew in accounts payable — affiliate on the Company's consolidated balance sheets as of March 31, 2019. The payable represents the remaining 80% of the equity commitment and will be funded on the date the Oahu Solar LLC projects reaches substantial completion. The Company, as a Class A member, is the primary beneficiary through its position as managing member and consolidates Oahu Partnership. Allocations of income and taxable items are equal to the distributions of available cash, which is currently 95% to the Company and 5% to Clearway Renew.

The Company's acquisition of the Class A membership interests in the Oahu Partnership was accounted for as a transfer of assets under common control and was recorded at historical cost in accordance with ASC 805-50, Business Combinations - Related Issues. The difference between the cash paid and payable recorded and the historical value of the assets was recorded as a contribution from CEG and increased the balance of its noncontrolling interest.

Repowering Partnership LLC — On August 30, 2018, Wind TE Holdco, an indirect subsidiary of the Company, entered into a partnership with Clearway Renew LLC, an indirect subsidiary of CEG, in order to facilitate the repowering of wind facilities of two of its indirect subsidiaries, Elbow Creek Wind Project LLC and Wildorado Wind LLC. Wind TE Holdco contributed its interests in the two facilities and Clearway Renew LLC contributed a turbine supply agreement, including title to certain components that qualify for production tax credits. Wind TE Holdco is the managing member of Repowering Partnership LLC and consolidates the entity, which is a VIE. Clearway Renew LLC is entitled to allocations of 21% of income, which is reflected in Wind TE Holdco’s noncontrolling interests.

Wind TE Holdco Buyout — On January 2, 2019, the Company bought out 100% of the Class A membership interests from the tax equity investor of Wind TE Holdco, for cash consideration of $19 million. The Company recorded the difference between the value of the interest bought and the cash received to equity and allocated it between non-controlling interest and additional paid in capital based on the economic ownership interest between CEG and public interest as of January 2, 2019.

Buckthorn Renewables, LLC — As described in Note 3, Business Acquisitions, on March 30, 2018, the Company acquired 100% of NRG’s interest in a 154 MW construction-stage utility-scale solar generation project, Buckthorn Renewables, LLC, which owns 100% interest in Buckthorn Solar Portfolio, LLC, which in turn owns 100% of the Class B membership interests in Buckthorn Holdings, LLC. Buckthorn Holdings, LLC is a tax equity fund, which is a variable interest entity that is consolidated by Buckthorn Solar Portfolio, LLC. The Company is the primary beneficiary, through its position as managing member, and indirectly consolidates Buckthorn Holdings, LLC through Buckthorn Solar Portfolio, LLC. The Class A member's interest in the tax equity fund is reflected as noncontrolling interest on the Company’s consolidated balance sheet. The Company utilizes the HLBV method to determine the net income or loss allocated to the tax equity investor noncontrolling interest.

Summarized financial information for the Company's consolidated VIEs consisted of the following as of March 31, 2019:

Fair Value of Financial Instruments

3 Months Ended

Mar. 31, 2019

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 payable, accounts payable — affiliates, 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 March 31, 2019				As of December 31, 2018
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
(In millions)
Liabilities:
Long-term debt — affiliate, including current portion	44		42		259		257
Long-term debt — external, including current portion (a)	$	5,842	$	5,825	$	5,779	$	5,681

^(a) Excludes deferred financing 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 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 March 31, 2019 and December 31, 2018:

	As of March 31, 2019				As of December 31, 2018
	Level 2		Level 3		Level 2		Level 3
	(In millions)
Long-term debt, including current portion	$	1,474	$	4,393	$	1,358	$	4,580

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 March 31, 2019						As of December 31, 2018

^(a) There were no derivative assets or liabilities classified as Level 1 as of March 31, 2019, and no derivative assets or liabilities classified as Level 1 or Level 3 as of December 31, 2018.

The following table reconciles, for the three months ended March 31, 2019, the beginning and ending balances for instruments that are recognized at fair value in the condensed consolidated financial statements using significant unobservable inputs:

(In millions)	Fair Value Measurement Using Significant Unobservable Inputs (Level 3)
Beginning balance as of January 1, 2019	$	—
Purchases	(7		)
Ending balance as of March 31, 2019	$	(7	)

There were no gains or losses for the period included in earnings attributable to the change in unrealized gains or losses relating to assets or liabilities still held as of March 31, 2019.

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 March 31, 2019, contracts valued with prices provided by models and other valuation techniques make up 17% 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 March 31, 2019:

	March 31, 2019
	Fair Value						Input/Range
	Assets		Liabilities		Valuation Technique	Significant Unobservable Input	Low	High	Weighted Average
(In millions)
Power Contracts	$	—	$	7	Discounted Cash Flow	Forward Market Price (per MWh)	5	55	15

The following table provides sensitivity of fair value measurements to increases/(decreases) in significant unobservable inputs as of March 31, 2019:

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 March 31, 2019, the non-performance reserve was $2 million gain in cost of operations and interest expense. 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 2018 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, which the Company is unable to predict.

On January 29, 2019, PG&E filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code.

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Contingencies

This note should be read in conjunction with the complete description under Note 14, Commitments and Contingencies, to the Company's 2018 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 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. The Company believes the allegations of NPPD are meritless and the Company is vigorously defending its rights under the PPAs.

Leases [Abstract]

Leases

Leases

Adoption of Topic 842

The Company adopted ASU No. 2019-01, Leases (Topic 842), or Topic 842, on January 1, 2019 using the modified retrospective transition method and therefore, prior period financial information has not been adjusted and continues to be reflected in accordance with the Company’s historical accounting policy. Topic 842 requires the establishment of a lease liability and related right-of-use, or ROU, asset for all leases with a term longer than 12 months. The Company elected certain of the permitted practical expedients, including the expedient that permits the Company to retain its existing lease assessment and classification. The Company also elected to account for lease and non-lease components for specific asset classes as a single lease component.

The adoption of the standard resulted in the recording of operating lease liabilities of $174 million and related ROU assets of $168 million. There was no impact to the Company’s consolidated statement of operations or cash flows. The Company utilized its incremental borrowing rate at adoption date, ranging from 4.04% - 4.67%, to determine the amount of the lease liabilities.

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 March 31, 2019.

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.

The majority of the Company’s revenue is obtained through PPAs or other contractual agreements that are accounted for as leases. 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 of the Company’s leases are operating leases. Certain of these leases have both lease and non-lease components, and the Company allocates the transaction price to the components based on standalone selling prices.

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).

Noncontrolling Interests

Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance in ASC 606, Revenue from Contracts with Customers, orTopic 606, using the modified retrospective method applied to contracts which were not completed as of the adoption date, with no adjustment required to the financial statements upon adoption. Following the adoption of the new standard, the Company’s revenue recognition of its contracts with customers remains materially consistent with its historical practice. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. 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 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.

Power Purchase Agreements, or PPAs

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. ASC 840 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 capital lease.

Renewable Energy Credits, or RECs

As stated above, 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.

Sale of Emission Allowances

The Company records its bank of emission allowances as part of intangible assets. From time to time, management may authorize the transfer of emission allowances in excess of usage from the Company's emission bank to intangible assets held-for-sale for trading purposes. The Company records the sale of emission allowances on a net basis within operating revenue in the Company's consolidated statements of operations.
