Direct Energy is a leading retail provider of electricity, natural gas, and home and business energy related products and services in North America, with operations in all 50 U.S. states and 8 Canadian provinces.

Refer to Note 4, Acquisitions and Dispositions, for further discussion of the acquisition of Direct Energy.
The acquired operations of Direct Energy are integrated into the existing NRG segment structure.

The East segment will also include the deregulated customer and market operations of Canada. The West/Services/Other segment will also include activity related to the regulated operations in Alberta, Canada and the services businesses.

Segments
As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments from Retail and Generation to Texas, East and West/Other beginning in the first quarter of 2020. The Company's updated segment structure reflects how management currently makes financial decisions and allocates resources.
The Company's businesses are segregated as follows:
Texas, which includes all activity related to customer, plant and market operations in Texas;
East, which includes the remaining activity related to customer operations and all activity related to plant and market operations in the East;
West/Other, which includes the following assets and activities: (i) all activity related to plant and market operations in the West, (ii) activity related to the Cottonwood power plant that was sold to Cleco on February 4, 2019 and is being leased back until 2025, (iii) the remaining renewables activity, including the Company’s equity method investments in Ivanpah Master Holdings, LLC and Agua Caliente, the remaining Home Solar assets and the NFL stadium solar generating assets, and (iv) activity related to the Company’s equity method investment for the Gladstone power plant in Australia; and

All affected disclosures have been recast to reflect these changes for all periods presented. For further discussion of segment reporting, refer to Note 13, Segment Reporting.
COVID-19
In March 2020, the World Health Organization categorized COVID-19 as a pandemic and the President of the United States declared the COVID-19 outbreak a national emergency. Electricity was deemed a 'critical and essential business operation' under various state and federal governmental COVID-19 mandates. NRG had activated its Crisis Management Team ("CMT") in January 2020 to proactively manage the Company's response to the impacts of COVID-19.
NRG continues to remain focused on protecting the health and well-being of its employees, while supporting its customers and the communities in which it operates and assuring the continuity of its operations. During the second quarter of 2020, the Company began to evaluate and implement protocols for return to normal work operations.

14

The Company continues to maintain certain restrictions on business travel and face-to-face sales channels, remote work practices remain in place and there are enhanced cleaning and hygiene protocols in all of its facilities. In addition, select essential employees and contractors are continuing to report to plant and certain office locations. The Company also continues to require pre-entry screening, including temperature checks, separation of work crews, additional personal protective equipment for employees and contractors when social distancing cannot be maintained, and a ban on all non-essential visitors. The Company has not experienced any material disruptions in its ability to continue its business operations to date.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Reclassifications
Certain prior year amounts have been reclassified for comparative purposes. The reclassifications did not affect consolidated results from operations, net assets or consolidated cash flows.

Credit Losses
On January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, or ASU No. 2016-13, using the modified retrospective approach. Following the adoption of the new standard, the Company’s process of estimating expected credit losses remains materially consistent with its historical practice. Information prior to January 1, 2020, which was previously referred to as the allowance and provision for bad debt, has not been restated and continues to be reported under the accounting standards in effect for that period.
Retail trade receivables are reported on the balance sheet net of the allowance for credit losses. The Company accrues an allowancea provision for current expected credit losses based on (i) estimates of uncollectible revenues by analyzing accounts receivable aging and current and reasonable forecasts of expected economic factors including, but not limited to, unemployment rates and weather-related events, (ii) historical collections and delinquencies, and (iii) counterparty credit ratings for commercial and industrial customers.
The following table represents the activity in the allowance for credit losses for the three and six months ended June 30, 2020:March 31, 2021:

15

The increase in the provision for credit losses during the three months ended March 31, 2021, compared to the same period in 2020 was primarily due to the impacts of Winter Storm Uri on bilateral finance hedging risk of $393 million, counterparty credit risk of $109 million and ERCOT default shortfall payments of $83 million, as well as the acquisition of Direct Energy.
Restricted Cash
The following table provides a reconciliation of cash and cash equivalents, restricted cash and funds deposited by counterparties reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the statements of cash flows:
(In millions)June 30, 2020December 31, 2019

Funds deposited by counterparties55 19 
Restricted cash18 
Cash and cash equivalents, funds deposited by counterparties and restricted cash shown in the statement of cash flows$574 $3,930 
Funds deposited by counterparties consist of cash held by the Company as a result of collateral posting obligations from its counterparties. Some amounts are segregated into separate accounts that are not contractually restricted but, based on the Company's intention, are not available for the payment of general corporate obligations. Depending on market fluctuations and the settlement of the underlying contracts, the Company will refund this collateral to the hedge counterparties pursuant to the terms and conditions of the underlying trades. Since collateral requirements fluctuate daily and the Company cannot predict if any collateral will be held for more than twelve months, the funds deposited by counterparties are classified as a current asset on the Company's balance sheet, with an offsetting liability for this cash collateral received within current liabilities.
Restricted cash consists primarily of funds held within the Company's projects that are restricted for specific uses.
Pension Plan Contributions
On March 27, 2020, the Senate passed the CARES Act to provide necessary emergency relief related to the COVID-19 pandemic. The CARES Act allows NRG and other pension plan sponsors to postpone 2020 contributions until January 1, 2021. As a result, NRG will consider deferring approximately $47 million in cash contributions previously planned to be made to the Company's pension plans in 2020. NRG’s pension and postretirement benefit plans are further described in Note 15, Benefit Plans and Other Postretirement Benefits, to the Company’s 2019 Form 10-K.

Note 4 — Acquisitions and Dispositions
Acquisitions
Direct Energy Acquisition
On January 5, 2021 (the "Acquisition Closing Date"), the Company acquired all of the issued and outstanding common shares of Direct Energy, a North American subsidiary of Centrica. Direct Energy is a leading retail provider of electricity, natural gas, and home and business energy related products and services in North America, with operations in all 50 U.S. states and 8 Canadian provinces. The acquisition increased NRG's retail portfolio by over 3 million customers and strengthens its integrated model. It also broadens the Company's presence in the Northeast and into states and locales where it did not previously operate, supporting NRG's objective to diversify its business.
The Company paid an aggregate purchase price of $3.625 billion in cash and an initial purchase price adjustment of $77 million. The Company funded the purchase price using a combination of $715 million of cash on hand, $166 million from a draw on its Revolving Credit Facility (of which $107 million was used to fund acquisition costs and financing fees that are not included in the aggregate purchase price above), as well as approximately $2.9 billion in secured and unsecured corporate debt issued in December 2020. The final purchase price adjustment resulted in a reduction of $38 million. The Company expects to receive this payment from Centrica during the second quarter of 2021. The Company also increased its collective liquidity and collateral facilities by $3.4 billion as of the Acquisition Closing Date to meet the additional liquidity requirements related to the acquisition, as detailed in the following table:

For further discussion see Note 9, Long-term Debt and Finance Leases, and alsoNote 13, Receivables Securitization and Repurchase Facility, to the Company's 2020 Form 10-K.
Acquisition costs were $22 million for the three months ended March 31, 2021 and are included in acquisition-related transaction and integration costs in the Company's consolidated statement of operations.
The acquisition has been recorded as a business combination under ASC 805 with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair values on the acquisition date. The initial accounting for the business combination is not complete because the evaluation necessary to assess the fair value of certain net assets acquired and the amount of goodwill to be recognized are still in process. The provisional amounts are subject to revision until the evaluations are completed to the extent that additional information is obtained about the facts and circumstances that existed as of the acquisition date.

Derivative Fair Value Measurements
A portion of NRG's contracts are exchange-traded contracts with readily available quoted market prices. A majority of NRG's contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations available through brokers or over-the-counter and on-line exchanges. 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 June 30, 2020,March 31, 2021, contracts valued with prices provided by models and other valuation techniques make up 38%9% of derivative assets and 31%4% of derivative liabilities.
NRG's significant positions classified as Level 3 include physical and financial natural gas and power contracts executed in illiquid markets, as well as FTRs. The significant unobservable inputs used in developing fair value include illiquid natural gas and power location pricing, which is derived as a basis to liquid locations. The basis spread is based on observable market

data when available or derived from historic prices and forward market prices from similar observable markets when not available. For FTRs, NRG uses the most recent auction prices to derive the fair value.
The following tables quantify the significant unobservable inputs used in developing the fair value of the Company's Level 3 positions as of June 30, 2020March 31, 2021 and December 31, 2019:2020:

The fair value of each contract is discounted using a risk-free interest rate. In addition, the Company applies a credit reserve to reflect credit risk, which is calculated based on published default probabilities. As of June 30,March 31, 2021, the credit reserve resulted in a $14 million decrease primarily within cost of operations. As of December 31, 2020, the credit reserve resulted in a $1$2 million decrease in operating revenue andincrease primarily within cost of operations. As of December 31, 2019, the credit reserve did not result in a significant change in fair value in operating revenue and cost of operations.
Concentration of Credit Risk
In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, to the Company's 20192020 Form 10-K, the following is a discussion of the concentration of credit risk for the Company's contractual obligations. 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. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, as well as retail customer credit risk through its retail load activities.
Counterparty Credit Risk
The Company's counterparty credit risk policies are disclosed in its 20192020 Form 10-K. As of June 30, 2020,March 31, 2021, counterparty credit exposure, excluding credit exposure from RTOs, ISOs, registered commodity exchanges and certain long-term agreements, was $339$811 million and NRG held collateral (cash and letters of credit) against those positions of $76$140 million, resulting in a net exposure of $263$752 million. NRG periodically receives collateral from counterparties in excess of their exposure. Collateral amounts shown include such excess while net exposure shown excludes excess collateral received.

22


Approximately 49%43% of the Company's exposure before collateral is expected to roll off by the end of 2021.2022. Counterparty credit exposure is valued through observable market quotes and discounted at a risk free interest rate. The following tables highlight net counterparty credit exposure by industry sector and by counterparty credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for NRG with counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market and NPNS, and non-derivative transactions. The exposure is shown net of collateral held and includes amounts net of receivables or payables.

During Winter Storm Uri, the credit quality, diversification and termCompany experienced nonperformance by a counterparty in one of its bilateral financial hedging transactions, resulting in exposure of $393 million. The Company is pursuing all means available to enforce its obligations under this transaction but, given the size of the exposure, incannot determine with certainty what the portfolio, NRG does not anticipateamount of its ultimate recovery will be. The full exposure was recorded as a material impact on its financial position or resultsprovision for credit losses as of operations from nonperformance by any of NRG's counterparties.March 31, 2021.
RTOs and ISOs
The Company participates in the organized markets of CAISO, ERCOT, AESO, IESO, ISO-NE, MISO, NYISO and PJM, known as RTOs or ISOs. Trading in the majority of these markets is approved by FERC, orwhereas in the case of ERCOT, it is approved by the PUCT, and includeswhereas in the case of AESO and IESO, both exist provincially with AESO primarily subject to Alberta Utilities Commission and the IESO to the Ontario Energy Board. These ISOs may include credit policies that, under certain circumstances, require that losses arising from the default of one member on spot market transactions be shared by the remaining participants. As a result, the counterparty credit risk to these markets is limited to NRG’s share of the overall market and are excluded from the above exposures.
Exchange Traded Transactions
The Company enters into commodity transactions on registered exchanges, notably ICE, NYMEX and Nodal. These clearinghouses act as the counterparty and transactions are subject to extensive collateral and margining requirements. As a result, these commodity transactions have limited counterparty credit risk.
Long-Term Contracts
Counterparty credit exposure described above excludes credit risk exposure under certain long-term contracts, primarily solar PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company values 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. Based on these valuation techniques, as of June 30, 2020,March 31, 2021, aggregate credit risk exposure managed by NRG to these counterparties was approximately $672$925 million for the next five years.

Retail Customer Credit Risk
The Company is exposed to retail credit risk through the Company's retail electricity and gas providers, which serve C&I customersHome and the Mass market.Business customers. Retail credit risk results in losses when a customer fails to pay for services rendered. The losses may result from both non-payment of customer accounts receivable and the loss of in-the-money forward value. The Company manages retail credit risk through the use of established credit policies that include monitoring of the portfolio and the use of credit mitigation measures such as deposits or prepayment arrangements.
As of June 30, 2020,March 31, 2021, the Company's retail customer credit exposure to C&IHome and MassBusiness customers was diversified across many customers and various industries, as well as government entities. TheAs a result of Winter Storm Uri, the Company is also subjectincurred additional credit losses from Business customers primarily due to risk with respecta segment of customers whose contracts included a pass through of wholesale power prices which were significantly escalated during the storm and from customers who failed to its residential solar customers. Current economic conditions may affect the Company's customers' ability to pay billsmeet their obligations in a timely manner, which could increase customer delinquencies and may lead to an increase in credit losses.ERCOT load curtailment programs.

Note 6 — Nuclear Decommissioning Trust Fund
NRG's Nuclear Decommissioning Trust Fund assets, which are for the decommissioning of its 44% interest in STP, are comprised of securities classified as available-for-sale and recorded at fair value based on actively quoted market prices. NRG accounts for the Nuclear Decommissioning Trust Fund in accordance with ASC 980, Regulated Operations, because the Company's nuclear decommissioning activities are subject to approval by the PUCT with regulated rates that are designed to recover all decommissioning costs and that can be charged to and collected from the ratepayers per PUCT mandate. Since the Company is in compliance with PUCT rules and regulations regarding decommissioning trusts and the cost of decommissioning is the responsibility of the Texas ratepayers, not NRG, all realized and unrealized gains or losses (including other-than-temporary impairments) related to the Nuclear Decommissioning Trust Fund are recorded to the Nuclear Decommissioning Trust liability and are not included in net income or accumulated OCI, consistent with regulatory treatment.
The following table summarizes the aggregate fair values and unrealized gains and losses for the securities held in the trust funds, as well as information about the contractual maturities of those securities.

Note 12 — Earnings Per Share
Basic income per common share is computed by dividing net income by the weighted average number of common shares outstanding. Shares issued and treasury shares repurchased during the year are weighted for the portion of the year that they were outstanding. Diluted income per share is computed in a manner consistent with that of basic income per share while giving effect to all potentially dilutive common shares that were outstanding during the period. The outstanding non-qualified stock options, non-vested restricted stock units, market stock units, and relative performance stock units are not considered outstanding for purposes of computing basic income per share. However, these instruments are included in the denominator for purposes of computing diluted income per share under the treasury stock method. The Convertible Senior Notes are convertible, under certain circumstances, into the Company’s common stock, cash or combination thereof (at NRG's option). There is no dilutive effect for the Convertible Senior Notes due to the Company’s expectation to settle the liability in cash.
The reconciliation of NRG's basic and diluted income per share is shown in the following table:

ForCompany's publicly-traded long-term debt is based on quoted market prices and is classified as Level 2 within the three and six months ended June 30, 2020, the effective tax rates were higher than the statutory rate of 21% due to state tax expense partially offset by an excess tax benefit related to share-based compensation. For the same periods in 2019, the effective tax rates were lower than the statutory rate of 21% primarily due to the tax benefit for the change in valuation allowance partially offset by state tax expense.

Uncertain Tax Benefits
As of June 30, 2020, NRG had a non-current tax liability of $18 million for uncertain tax benefits from positions taken on various state income tax returns and accrued interest. For the six months ended June 30, 2020, NRG accrued an immaterial amount of interest relating to the uncertain tax benefits. As of June 30, 2020, NRG had cumulative interest and penalties related to these uncertain tax benefits of $2 million. The Company recognizes interest and penalties related to uncertain tax benefits in income tax expense.
NRG is subject to examination by taxing authorities for income tax returns filed in the U.S. federal jurisdiction and various state and foreign jurisdictions including operations located in Australia and Canada. The Company is no longer subject to U.S. federal income tax examinations for years prior to 2016. With few exceptions, state and local income tax examinations are no longer open for years prior to 2011.

Derivative Fair Value Measurements
A portion of NRG's contracts are exchange-traded contracts with readily available quoted market prices. A majority of NRG's contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations available through brokers or over-the-counter and on-line exchanges. 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, 2021, contracts valued with prices provided by models and other valuation techniques make up 9% of derivative assets and 4% of derivative liabilities.
NRG's significant positions classified as Level 3 include physical and financial natural gas and power contracts executed in illiquid markets, as well as FTRs. The significant unobservable inputs used in developing fair value include illiquid natural gas and power location pricing, which is derived as a basis to liquid locations. The basis spread is based on observable market

data when available or derived from historic prices and forward market prices from similar observable markets when not available. For FTRs, NRG uses the most recent auction prices to derive the fair value.

The fair value of each contract is discounted using a risk-free interest rate. In addition, the Company applies a credit reserve to reflect credit risk, which is calculated based on published default probabilities. As of March 31, 2021, the credit reserve resulted in a $14 million decrease primarily within cost of operations. As of December 31, 2020, the credit reserve resulted in a $2 million increase primarily within cost of operations.
Concentration of Credit Risk
In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, to the Company's 2020 Form 10-K, the following is a discussion of the concentration of credit risk for the Company's contractual obligations. 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. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, as well as retail customer credit risk through its retail load activities.
Counterparty Credit Risk
The Company's counterparty credit risk policies are disclosed in its 2020 Form 10-K. As of March 31, 2021, counterparty credit exposure, excluding credit exposure from RTOs, ISOs, registered commodity exchanges and certain long-term agreements, was $811 million and NRG held collateral (cash and letters of credit) against those positions of $140 million, resulting in a net exposure of $752 million. NRG periodically receives collateral from counterparties in excess of their exposure. Collateral amounts shown include such excess while net exposure shown excludes excess collateral received.

22


Approximately 43% of the Company's exposure before collateral is expected to roll off by the end of 2022. Counterparty credit exposure is valued through observable market quotes and discounted at a risk free interest rate. The following tables highlight net counterparty credit exposure by industry sector and by counterparty credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for NRG with counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market and NPNS, and non-derivative transactions. The exposure is shown net of collateral held and includes amounts net of receivables or payables.

(a)Counterparty credit exposure excludes uranium and coal transportation contracts because of the unavailability of market prices
(b)The figures in the tables above exclude potential counterparty credit exposure related to RTOs, ISOs, registered commodity exchanges and certain long-term contracts
The Company currently has no exposure to wholesale counterparties in excess of 10% of total net exposure discussed above as of March 31, 2021. Changes in hedge positions and market prices will affect credit exposure and counterparty concentration.
During Winter Storm Uri, the Company experienced nonperformance by a counterparty in one of its bilateral financial hedging transactions, resulting in exposure of $393 million. The Company is pursuing all means available to enforce its obligations under this transaction but, given the size of the exposure, cannot determine with certainty what the amount of its ultimate recovery will be. The full exposure was recorded as a provision for credit losses as of March 31, 2021.
RTOs and ISOs
The Company participates in the organized markets of CAISO, ERCOT, AESO, IESO, ISO-NE, MISO, NYISO and PJM, known as RTOs or ISOs. Trading in the majority of these markets is approved by FERC, whereas in the case of ERCOT, it is approved by the PUCT, and whereas in the case of AESO and IESO, both exist provincially with AESO primarily subject to Alberta Utilities Commission and the IESO to the Ontario Energy Board. These ISOs may include credit policies that, under certain circumstances, require that losses arising from the default of one member on spot market transactions be shared by the remaining participants. As a result, the counterparty credit risk to these markets is limited to NRG’s share of the overall market and are excluded from the above exposures.
Exchange Traded Transactions
The Company enters into commodity transactions on registered exchanges, notably ICE, NYMEX and Nodal. These clearinghouses act as the counterparty and transactions are subject to extensive collateral and margining requirements. As a result, these commodity transactions have limited counterparty credit risk.
Long-Term Contracts
Counterparty credit exposure described above excludes credit risk exposure under certain long-term contracts, primarily solar PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company values 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. Based on these valuation techniques, as of March 31, 2021, aggregate credit risk exposure managed by NRG to these counterparties was approximately $925 million for the next five years.

23


Retail Customer Credit Risk
The Company is exposed to retail credit risk through the Company's retail electricity and gas providers, which serve Home and Business customers. Retail credit risk results in losses when a customer fails to pay for services rendered. The losses may result from both non-payment of customer accounts receivable and the loss of in-the-money forward value. The Company manages retail credit risk through the use of established credit policies that include monitoring of the portfolio and the use of credit mitigation measures such as deposits or prepayment arrangements.
As of March 31, 2021, the Company's retail customer credit exposure to Home and Business customers was diversified across many customers and various industries, as well as government entities. As a result of Winter Storm Uri, the Company incurred additional credit losses from Business customers primarily due to a segment of customers whose contracts included a pass through of wholesale power prices which were significantly escalated during the storm and from customers who failed to meet their obligations in ERCOT load curtailment programs.

Since the Company is in compliance with PUCT rules and regulations regarding decommissioning trusts and the cost of NRG's costsdecommissioning is the responsibility of operating the plants. Certain agreements also include fees for administrative service, a base monthly fee, profit margin and/Texas ratepayers, not NRG, all realized and unrealized gains or annual incentive bonus.losses (including other-than-temporary impairments) related to the Nuclear Decommissioning Trust Fund are recorded to the Nuclear Decommissioning Trust liability and are not included in net income or accumulated OCI, consistent with regulatory treatment.

The reversals of acquired loss positions were valued based upon the forward prices on the acquisition date. The roll-off amounts were offset by realized gains or losses at the settled prices and are reflected in operating revenue or cost of operations during the same period.
For the three months ended March 31, 2021, the $559 unrealized gain from open economic hedge positions was primarily the result of an increase in value of forward positions due to increases in ERCOT power prices and ERCOT heat rate expansion.
For the three months ended March 31, 2020, the $34 million unrealized gain from open economic hedge positions was primarily the result of an increase in value of forward power positions due to decrease in West/Other power prices, as well as an increase in value of ERCOT heat rate positions due to ERCOT hear rate expansion.
Credit Risk Related Contingent Features
Certain of the Company's hedging agreements contain provisions that require the Company to post additional collateral if the counterparty determines that there has been deterioration in credit quality, generally termed “adequate assurance” under the agreements, or require the Company to post additional collateral if there were a downgrade in the Company's credit rating. In addition, as a result of the acquisition of Direct Energy from Centrica, certain of the Company’s agreements as of March 31, 2021, were still supported by credit support posted by Centrica, and as a result, could require the Company to post additional collateral upon a deterioration or downgrade of Centrica. The collateral required for contracts with adequate assurance clauses that are in a net liability position as of March 31, 2021 was $642 million. The Company is also party to certain marginable agreements under which it has net liability position, but the counterparty has not called for the collateral due, which was $91 million as of March 31, 2021. If called for by the counterparty, $57 million of additional collateral would be required for all contracts with credit rating contingent features as of March 31, 2021.

The Company's Limestone facility historically burned lignite obtained from the Jewett mine, which was operated by TWCC. On or about March 15, 2019, the Jewett mine and related lignite supply agreement with NRG were acquired by Westmoreland Jewett Mining LLC ("Jewett Mining"), a subsidiary of Westmoreland Mining LLC pursuant to a plan of reorganization confirmed by the Texas Bankruptcy Court.

Note 1811Environmental MattersChanges in Capital Structure
NRG is subject to a wide rangeAs of environmental laws in the development, construction, ownershipMarch 31, 2021 and operation of projects. These laws generally require that governmental permits and approvals be obtained before construction and during operation of power plants. NRG is also subject to laws regarding the protection of wildlife, including migratory birds, eagles and threatened and endangered species. The electric generation industry has been facing requirements regarding GHGs, combustion byproducts, water discharge and use, and threatened and endangered species that have been put in place in recent years. However, under the current U.S. presidential administration, some of these rules are being reconsidered and reviewed. In general, future laws are expected to require the addition of emissions controls or other environmental controls or to impose certain restrictions on the operations of the Company's facilities, which could have a material effect on the Company's consolidated financial position, results of operations, or cash flows. Federal and state environmental laws generally have become more stringent over time, although this trend could slow or pause in the near term with respect to federal laws under the current U.S. presidential administration.
Air
On July 8, 2019, EPA promulgated the ACE rule, which rescinded the CPP, which had sought to broadly regulate CO2 emissions from the power sector. The ACE rule requires states that have coal-fired EGUs to develop plans to seek heat rate improvements from coal-fired EGUs. Numerous parties have challenged the ACE rule in the D.C. Circuit and numerous parties have filed petitions for reconsideration with the EPA.
Water
Effluent Limitations Guidelines — In November 2015, the EPA revised the Effluent Limitations Guidelines for Steam Electric Generating Facilities, which would have imposed more stringent requirements (as individual permits were renewed) for wastewater streams from FGD, fly ash, bottom ash, and flue gas mercury control. On September 18, 2017, the EPA promulgated a final rule that, among other things, postpones the compliance dates to preserve the status quo for FGD wastewater and bottom ash transport water by two years to November 2020 until the EPA completes its next rulemaking. On April 12, 2019, the United States Court of Appeals for the Fifth Circuit addressed challenges to the rule brought by several environmental groups related to legacy wastewaters and coal ash leachate and remanded portions of the rule to the EPA. On November 22, 2019, the EPA proposed amending the 2015 ELG rule by: (x) decreasing the stringency of the selenium limit (but increasing the stringency of the nitrate and mercury limits) for FGD wastewater; (y) relaxing the zero-discharge requirement for bottom ash transport water; and (z) changing several deadlines. The Company has eliminated its estimate of the environmental capital expenditures that was anticipated. The Company will revisit these estimates after the rule is revised and as permits are renewed.
Byproducts, Wastes, Hazardous Materials and Contamination
In April 2015, the EPA finalized the rule regulating byproducts of coal combustion (e.g., ash and gypsum) as solid wastes under the RCRA. In September 2017, the EPA agreed to reconsider the rule. On July 30, 2018, the EPA promulgated a rule that amends the existing ash rule by extending some of the deadlines and providing more flexibility for compliance. On August 21, 2018, the D.C. Circuit found, among other things, that the EPA had not adequately regulated unlined ponds and legacy ponds. On August 14, 2019, the EPA proposed targeted changes to the April 2015 Rule including changes to address the August 2018 D.C. Circuit decision. On December 2, 2019, the EPA released for comment "Closure Part A Proposal" to revise the CCR Rule to address the D.C. Circuit's 2018 decision regarding the adequacy of clay-lined impoundments, obligations to close all unlined impoundments and related deadlines. On February 20,31, 2020, the EPA proposedCompany had 500,000,000 shares of common stock authorized. The following table reflects the framework for developingchanges in NRG's common stock issued and implementing a federal permit program for states that are not approved to administer the CCR rule. On March 3, 2020, the EPA proposed for comment "A Holistic Approach to Closure Part B," which proposes procedures for obtaining approval to operate existing impoundments with alternative liners. On July 29, 2020, the EPA released a prepublication (non-official) version of the final rule "A Holistic Approach to Closure Part A: Deadline to Initiate Closure," which when published in the Federal Register will amend the April 2015 Rule to address the August 2018 D.C. Circuit decision and extend some of the deadlines. The Company anticipates that the EPA will promulgate additional regulations to further amend the existing rule. The Company will update estimates of required environmental capital expenditures as the rule is revised.outstanding:

Acquisition costs were $22 million for the three months ended March 31, 2021 and are included in acquisition-related transaction and integration costs in the Company's consolidated statement of operations.
The acquisition has been recorded as a business combination under ASC 805 with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair values on the acquisition date. The initial accounting for the business combination is not complete because the evaluation necessary to assess the fair value of certain net assets acquired and the amount of goodwill to be recognized are still in process. The provisional amounts are subject to approval byrevision until the shareholders of Centrica, as well as customary closing conditions, consents and regulatory approvals, including the expiration or termination of the applicable waiting period under the HSR Act, and the receipt of approvals or expiration of applicable waiting periods under the Federal Power Act and the Canadian Competition Act.
The acquisition is targeted to close by December 31, 2020. Thereevaluations are no assurances that the conditionscompleted to the consummationextent that additional information is obtained about the facts and circumstances that existed as of the acquisition of Direct Energy will be satisfied, that Centrica will not seek or enter into an alternative transaction as discussed below, or that the acquisition of Direct Energy will be consummated on the terms agreed to, or at all.date.
Prior to the approval of the transaction by its shareholders, Centrica is permitted to respond to unsolicited acquisition proposals that constitute or are reasonably likely to lead to a superior proposal, and to engage in negotiations with, and provide information to, parties that submit these proposals. Centrica can terminate the Purchase Agreement to accept a superior proposal. In addition, the board of directors of Centrica can change its recommendation in favor of NRG's transaction if the failure to do so would be inconsistent with the fiduciary duties of the Centrica directors, in which case the Purchase Agreement would automatically terminate. In the event of a termination of the Purchase Agreement in connection with (i) Centrica's decision to accept a superior proposal, (ii) the failure to obtain Centrica shareholder approval, or (iii) a change of recommendation by the Centrica board, Centrica would be obligated to pay NRG a termination fee of approximately $30 million.
NRG will be required to pay Centrica a termination fee of $180 million if the Purchase Agreement is terminated (i) by either Centrica or NRG because the transaction has not been completed by July 24, 2021 (as such date may be extended for two separate three month periods if necessary to obtain required regulatory approvals, through January 24, 2022), and at the time of termination all of the mutual conditions to the obligations of NRG and Centrica to close the acquisition, and all the conditions to NRG's obligations to close the acquisition, have been satisfied other than receipt of the required antitrust and competition approvals, (ii) by either Centrica or NRG if a governmental entity has issued a judgment with respect to an antitrust or competition law that permanently prohibits the completion of the transaction and the judgment has become final and non-appealable, (iii) by NRG if a governmental entity has imposed a condition on its willingness to approve the acquisition on antitrust or competition grounds and the condition has a material adverse effect as described in the Purchase Agreement or (iv) by Centrica because NRG has breached its obligations under the Purchase Agreement to seek to obtain the antitrust and competition approvals required to complete the transaction.
Midwest Generation Lease Purchase

The Company intends to fund the purchase with borrowings under its Revolving Credit Facility in an amount equal to the existing operating lease liabilities of $148 million as of June 30, 2020 and the remainder from cash-on-hand. The closing is conditioned, among other items, on the receipt of regulatory approvals from FERC and under the HSR Act.

Derivative Fair Value Measurements
A portion of NRG's contracts are exchange-traded contracts with readily available quoted market prices. A majority of NRG's contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations available through brokers or over-the-counter and on-line exchanges. 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, 2021, contracts valued with prices provided by models and other valuation techniques make up 9% of derivative assets and 4% of derivative liabilities.
NRG's significant positions classified as Level 3 include physical and financial natural gas and power contracts executed in illiquid markets, as well as FTRs.

The fair value of each contract is discounted using a risk-free interest rate. In addition, the Company applies a credit reserve to reflect credit risk, which is calculated based on published default probabilities. As of March 31, 2021, the credit reserve resulted in a $14 million decrease primarily within cost of operations. As of December 31, 2020, the credit reserve resulted in a $2 million increase primarily within cost of operations.
Concentration of Credit Risk
In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, to the Company's 2020 Form 10-K, the following is a discussion of the concentration of credit risk for the Company's contractual obligations. 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. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, as well as retail customer credit risk through its retail load activities.
Counterparty Credit Risk
The Company's counterparty credit risk policies are disclosed in its 2020 Form 10-K. As of March 31, 2021, counterparty credit exposure, excluding credit exposure from RTOs, ISOs, registered commodity exchanges and certain long-term agreements, was $811 million and NRG held collateral (cash and letters of credit) against those positions of $140 million, resulting in a net exposure of $752 million. NRG periodically receives collateral from counterparties in excess of their exposure. Collateral amounts shown include such excess while net exposure shown excludes excess collateral received.

4122


Approximately 43% of the Company's exposure before collateral is expected to roll off by the end of 2022. Counterparty credit exposure is valued through observable market quotes and discounted at a risk free interest rate. The following tables highlight net counterparty credit exposure by industry sector and by counterparty credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for NRG conducts muchwith counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market and NPNS, and non-derivative transactions. The exposure is shown net of collateral held and includes amounts net of receivables or payables.

The Company currently has no exposure to wholesale counterparties in excess of 10% of total net exposure discussed above as of March 31, 2021. Changes in hedge positions and market prices will affect credit exposure and counterparty concentration.
During Winter Storm Uri, the Company experienced nonperformance by a counterparty in one of its business through and derives muchbilateral financial hedging transactions, resulting in exposure of $393 million. The Company is pursuing all means available to enforce its obligations under this transaction but, given the size of the exposure, cannot determine with certainty what the amount of its incomeultimate recovery will be. The full exposure was recorded as a provision for credit losses as of March 31, 2021.
RTOs and ISOs
The Company participates in the organized markets of CAISO, ERCOT, AESO, IESO, ISO-NE, MISO, NYISO and PJM, known as RTOs or ISOs. Trading in the majority of these markets is approved by FERC, whereas in the case of ERCOT, it is approved by the PUCT, and whereas in the case of AESO and IESO, both exist provincially with AESO primarily subject to Alberta Utilities Commission and the IESO to the Ontario Energy Board. These ISOs may include credit policies that, under certain circumstances, require that losses arising from its subsidiaries. Therefore, the Company's abilitydefault of one member on spot market transactions be shared by the remaining participants. As a result, the counterparty credit risk to make required payments with respectthese markets is limited to its indebtedness and other obligations depends on the financial results and condition of its subsidiaries and NRG's ability to receive funds from its subsidiaries. There are no restrictions on the ability of anyNRG’s share of the guarantor subsidiaries to transfer funds to NRG. However, there may be restrictions for certain non-guarantor subsidiaries.overall market and are excluded from the above exposures.
Exchange Traded Transactions
The following condensed consolidating financial information presentsCompany enters into commodity transactions on registered exchanges, notably ICE, NYMEX and Nodal. These clearinghouses act as the financial information of NRG Energy, Inc.,counterparty and transactions are subject to extensive collateral and margining requirements. As a result, these commodity transactions have limited counterparty credit risk.
Long-Term Contracts
Counterparty credit exposure described above excludes credit risk exposure under certain long-term contracts, primarily solar PPAs. As external sources or observable market quotes are not available to estimate such exposure, the guarantor subsidiaries and the non-guarantor subsidiaries in accordance with Rule 3-10 of Regulation S-XCompany values these contracts based on various techniques including, but not limited to, internal models based on a fundamental analysis of the Securities Act. The financial information may not necessarily be indicativemarket and extrapolation of resultsobservable market data with similar characteristics. Based on these valuation techniques, as of operations or financial position hadMarch 31, 2021, aggregate credit risk exposure managed by NRG to these counterparties was approximately $925 million for the guarantor subsidiaries or non-guarantor subsidiaries operated as independent entities.

Retail Customer Credit Risk
The Company is exposed to retail credit risk through the Company's retail electricity and gas providers, which serve Home and Business customers. Retail credit risk results in losses when a customer fails to pay for services rendered. The losses may result from both non-payment of customer accounts receivable and the loss of in-the-money forward value. The Company manages retail credit risk through the use of established credit policies that include monitoring of the portfolio and the use of credit mitigation measures such as deposits or prepayment arrangements.
As of March 31, 2021, the Company's retail customer credit exposure to Home and Business customers was diversified across many customers and various industries, as well as government entities. As a result of Winter Storm Uri, the Company incurred additional credit losses from Business customers primarily due to a segment of customers whose contracts included a pass through of wholesale power prices which were significantly escalated during the storm and from customers who failed to meet their obligations in ERCOT load curtailment programs.

Note 6 — Nuclear Decommissioning Trust Fund
NRG's Nuclear Decommissioning Trust Fund assets, which are for the decommissioning of its 44% interest in STP, are comprised of securities classified as available-for-sale and recorded at fair value based on actively quoted market prices. NRG accounts for the Nuclear Decommissioning Trust Fund in accordance with ASC 980, Regulated Operations, because the Company's nuclear decommissioning activities are subject to approval by the PUCT with regulated rates that are designed to recover all decommissioning costs and that can be charged to and collected from the ratepayers per PUCT mandate. Since the Company is in compliance with PUCT rules and regulations regarding decommissioning trusts and the cost of decommissioning is the responsibility of the Texas ratepayers, not NRG, all realized and unrealized gains or losses (including other-than-temporary impairments) related to the Nuclear Decommissioning Trust Fund are recorded to the Nuclear Decommissioning Trust liability and are not included in net income or accumulated OCI, consistent with regulatory treatment.
The following table summarizes the aggregate fair values and unrealized gains and losses for the securities held in the trust funds, as well as information about the contractual maturities of those securities.

The reversals of acquired loss positions were valued based upon the forward prices on the acquisition date. The roll-off amounts were offset by realized gains or losses at the settled prices and are reflected in operating revenue or cost of operations during the same period.
For the three months ended June 30,March 31, 2021, the $559 unrealized gain from open economic hedge positions was primarily the result of an increase in value of forward positions due to increases in ERCOT power prices and ERCOT heat rate expansion.
For the three months ended March 31, 2020, the $34 million unrealized gain from open economic hedge positions was primarily the result of an increase in value of forward power positions due to decrease in West/Other power prices, as well as an increase in value of ERCOT heat rate positions due to ERCOT hear rate expansion.

Certain of the Company's hedging agreements contain provisions that require the Company to post additional collateral if the counterparty determines that there has been deterioration in credit quality, generally termed “adequate assurance” under the agreements, or require the Company to post additional collateral if there were a downgrade in the Company's credit rating. In addition, as a result of the acquisition of Direct Energy from Centrica, certain of the Company’s agreements as of March 31, 2021, were still supported by credit support posted by Centrica, and as a result, could require the Company to post additional collateral upon a deterioration or downgrade of Centrica. The collateral required for contracts with adequate assurance clauses that are in a net liability position as of March 31, 2021 was $642 million. The Company is also party to certain marginable agreements under which it has net liability position, but the counterparty has not called for the collateral due, which was $91 million as of March 31, 2021. If called for by the counterparty, $57 million of additional collateral would be required for all contracts with credit rating contingent features as of March 31, 2021.

Note 8 — Impairments
2020 Impairment Losses
Petra Nova Parish Holdings — During the first quarter of 2020, due to the decline in consolidationoil prices, NRG determined that the carrying amount of the Company’s equity method investment exceeded the fair value of the investment and that the decline is considered to be other-than-temporary. In determining the fair value, the Company utilized an income approach to estimate future project cash flows. The Company recorded an impairment loss of $18 million in the Texas segment, which included the anticipated drawdown of the $12 million letter of credit posted in September 2019 to cover certain project debt reserve requirements.

Recourse Debt
Revolving Credit Facility
During the third quarter of 2020, the Company amended its existing credit agreement to, among other things, (i) increase the existing revolving commitments in an aggregate amount of $802 million, and (ii) provide for a new tranche of revolving commitments in an aggregate amount of $273 million with a maturity date that is 30 months after the date of closing of the Direct Energy acquisition. The maturity date of the new revolving tranche of commitments may, upon request by the Company, and at the option of each applicable lender under the new tranche be extended by 12 months, but not beyond May 28, 2024, which is the maturity date of the existing and increased commitments. Other than with respect to the maturity date, the terms of all revolving commitments and loans made pursuant thereto are identical. The increase in the existing commitments, and the commitments with respect to the new tranche were effective on August 20, 2020 and became available upon January 5, 2021. As of March 31, 2021, total revolving commitments available, subject to usage, under the amended credit agreement was $3.7 billion. As of March 31, 2021, $750 million of borrowings were outstanding. As of May 6, 2021, there were $70 million of borrowings outstanding.
Non-Recourse Debt
Put Option Agreement for Senior Debt Issuance
As further discussed in Part IV, Item 15, Note 14, Long-term Debt and Finance Leases of the Company's 2020 Form 10-K, the Company entered into a Put Option Agreement for Senior Debt Issuances (the “P-Caps”). In connection with the issuance of the P-Caps, on December 11, 2020, NRG entered into an amended and restated facility agreement for the issuance of letters of credit (the “LC Agreement”) with Deutsche Bank Trust Company Americas as collateral agent (the “Collateral Agent”) and administrative agent pursuant to which certain financial institutions (the “LC Issuers”) have agreed to provide letters of credit in an aggregate amount not to exceed $874 million to support the operations of NRG and its subsidiaries and

4428


minority investments, including to replace certain letters of credit and other credit support issued for the account of entities acquired pursuant to the Direct Energy Acquisition. In addition, on December 11, 2020, the Trust entered into an amended and restated pledge and control agreement (the “Pledge Agreement”), among NRG, the Trust and the Collateral Agent for the LC Issuers, under which the Trust agreed to grant a pledge over the Eligible Treasury Assets in favor of the Collateral Agent for the benefit of the LC Issuers. Pursuant to the LC Agreement and the Pledge Agreement, the Collateral Agent is entitled to withdraw Eligible Treasury Assets from the Trust’s pledged account, following notice to NRG, in the event NRG has failed to reimburse amounts drawn under any letter of credit issued pursuant to the LC Agreement, and the LC Issuers have the right to instruct the Collateral Agent to enforce the pledge over the Eligible Treasury Assets upon the occurrence of any event of default under the LC Agreement (a “Collateral Enforcement Event”). The LC Agreement and the Pledge Agreement were available on January 5, 2021. As of March 31, 2021, $689 million of letters of credit were issued under the LC Agreement.

Note 10 — Investments Accounted for Using the Equity Method and Variable Interest Entities, or VIEs
Entities that are not Consolidated
NRG accounts for the Company's significant investments using the equity method of accounting. NRG's carrying value of equity investments can be impacted by a number of elements including impairments, unrealized gains and losses on derivatives and movements in foreign currency exchange rates. On February 3, 2021, the Company sold its 35% ownership in Agua Caliente to Clearway Energy, Inc. for $202 million as further described in Note 4, Acquisitions and Dispositions.
Variable Interest Entities that are Consolidated
The Company has a controlling financial interest that has been identified as a VIE under ASC 810 in NRG Receivables LLC, which has entered into financing transactions related to the Receivables Facility as further described in Note 13, Receivables Securitization and Repurchase Facility, to the Company’s 2020 Form 10-K.

Note 11 — Changes in Capital Structure
As of March 31, 2021 and December 31, 2020, the Company had 500,000,000 shares of common stock authorized. The following table reflects the changes in NRG's common stock issued and outstanding:

Employee Stock Purchase Plan
In March 2019, the Company reopened participation in the ESPP, which allows eligible employees to elect to withhold between 1% and 10% of their eligible compensation to purchase shares of NRG common stock at the lesser of 95% of its market value on the offering date or 95% of the fair market value on the exercise date. An offering date occurs each April 1 and October 1. An exercise date occurs each September 30 and March 31.
NRG ENERGY, INC. AND SUBSIDIARIESCommon Stock Dividends
CONDENSED CONSOLIDATING STATEMENTS OF COMPREHENSIVE INCOME/(LOSS)During the first quarter of 2021, NRG increased the annual dividend to $1.30 from $1.20 per share and expects to target an annual dividend growth rate of 7-9% per share in subsequent years. A quarterly dividend of $0.325 per share was paid on the Company's common stock during the three months ended March 31, 2021. On April 19, 2021, NRG declared a quarterly dividend on the Company's common stock of $0.325 per share, payable on May 17, 2021 to stockholders of record as of May 3, 2021.

29


The Company's common stock dividends are subject to available capital, market conditions, and compliance with associated laws, regulations and other contractual obligations.

Note 12 — (Loss)/Income Per Share
Basic (loss)/income per common share is computed by dividing net (loss)/income by the weighted average number of common shares outstanding. Shares issued and treasury shares repurchased during the year are weighted for the portion of the year that they were outstanding. Diluted (loss)/income per share is computed in a manner consistent with that of basic (loss)/income per share while giving effect to all potentially dilutive common shares that were outstanding during the period. The outstanding relative performance stock units, non-vested restricted stock units, market stock units, and non-qualified stock options are not considered outstanding for purposes of computing basic (loss)/income per share. However, these instruments are included in the denominator for purposes of computing diluted (loss)/income per share under the treasury stock method. The Convertible Senior Notes are convertible, under certain circumstances, into the Company’s common stock, cash or combination thereof (at NRG's option). There is no dilutive effect for the Convertible Senior Notes due to the Company’s expectation to settle the liability in cash.
The reconciliation of NRG's basic and diluted (loss)/income per share is shown in the following table:
Three months ended March 31,
(In millions, except per share data)20212020
Basic (loss)/income per share:
Net (loss)/income$(82)$121

 (Loss)/income per weighted average common share — diluted$(0.33)$0.49 

As of March 31, 2021, the Company had 1 million shares of outstanding equity instruments that are anti-dilutive and were not included in the computation of the Company’s diluted loss per share. As of March 31, 2020, the Company had an insignificant number of outstanding equity instruments that are anti-dilutive and were not included in the computation of the Company’s diluted income per share.

Note 13 — Segment Reporting
The Company’s segment structure reflects how management currently makes financial decisions and allocates resources. The Company manages its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus.
NRG’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, free cash flow and allocation of capital, as well as net income/(loss).

30


The acquired operations of Direct Energy are integrated into the existing NRG segment structure. Domestic customer and market operations are combined into the corresponding geographical segments of Texas, East and West/Services/Other. The East segment includes the deregulated customer and market operations of Canada. The West/Services/Other segment includes activity related to the regulated operations in Alberta, Canada and the services businesses.

the effective tax rate was lower than the statutory rate of 21% primarily due to an excess tax benefit related to share-based compensation, partially offset by state tax expense.
(a)All significant intercompanyUncertain Tax Benefits
As of March 31, 2021, NRG had a non-current tax liability of $23 million for uncertain tax benefits from positions taken on various federal and state income tax returns and accrued interest. For the three months ended March 31, 2021, NRG accrued an immaterial amount of interest relating to the uncertain tax benefits. As of March 31, 2021, NRG had cumulative interest and penalties related to these uncertain tax benefits of $2 million. The Company recognizes interest and penalties related to uncertain tax benefits in income tax expense.
NRG is subject to examination by taxing authorities for income tax returns filed in the U.S. federal jurisdiction and various state and foreign jurisdictions including operations located in Australia and Canada. The Company is no longer subject to U.S. federal income tax examinations for years prior to 2017. With few exceptions, state and local income tax examinations are no longer open for years prior to 2012.
Note 15 — Related Party Transactions
NRG provides services to some of its equity method investments under operations and maintenance agreements. Fees for the services under these agreements include recovery of NRG's costs of operating the plants. Certain agreements also include fees for administrative service, a base monthly fee, profit margin and/or annual incentive bonus.

First Lien Structure
NRG has granted first liens to certain counterparties on a substantial portion of property and assets owned by NRG and the guarantors of its senior debt. NRG uses the first lien structure to reduce the amount of cash collateral and letters of credit that it would otherwise be required to post from time to time to support its obligations under out-of-the-money hedges. To the extent that the underlying hedge positions for a counterparty are out-of-the-money to NRG, the counterparty may have a claim under the first lien program. As of March 31, 2021, all hedges under the first lien program were in-the-money for NRG on a counterparty aggregate basis.
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. NRG records accruals 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 accrual for the applicable legal matters, including regulatory and environmental matters as further discussed in Note 17, Regulatory Matters, and Note 18, Environmental Matters. In addition, legal costs are expensed as incurred. Management has assessed each of the following matters based on current information and made a judgment concerning its potential outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success. Unless specified below, the Company is unable to predict the outcome of these legal proceedings 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 their currently recorded accruals and that such differences could be material.

4532


In addition to the legal proceedings noted below, NRG ENERGY, INC. AND SUBSIDIARIESand 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 NRG's consolidated financial position, results of operations, or cash flows.

Environmental Lawsuits
(a)Sierra club et al. v. Midwest Generation LLCAll significant intercompany transactions — In 2012, several environmental groups filed a complaint against Midwest Generation with the Illinois Pollution Control Board ("IPCB") alleging violations of environmental law resulting in groundwater contamination. In June 2019, the IPCB found that Midwest Generation violated the law because it had improperly handled coal ash at 4 facilities in Illinois and caused or allowed coal ash constituents to impact groundwater. On September 9, 2019, Midwest Generation filed a Motion to Reconsider numerous issues, which the court granted in part and denied in part on February 6, 2020. The IPCB will hold hearings to determine the appropriate relief. Midwest Generation has been working with the Illinois EPA to address the groundwater issues since 2010.
Consumer Lawsuits
Similar to other energy service companies (“ESCOs”) operating in the industry, from time-to-time, the Company and/or its subsidiaries may be subject to consumer lawsuits in various jurisdictions where they sell natural gas and electricity.
Variable Price Cases — In the cases set forth below, referred to as the Variable Price Cases, such actions involve consumers alleging that one of the Company’s ESCOs promised that consumers would pay the same or less than they would have paid if they stayed with their default utility or previous energy supplier. The underlying claims of each case are similar and the Company continues to deny the allegations and is vigorously defending these matters.
XOOM Energy
XOOM Energy is a defendant in a putative class action lawsuit pending in New York. This case is in the discovery phase.
Direct Energy
There are 4 putative class actions pending against Direct Energy: (1) Linda Stanley v. Direct Energy (S.D.N.Y Apr. 2019) - The parties recently agreed to mediate this matter. In the interim, all written discovery is stayed. Direct Energy plans to depose the plaintiff in the next 60 days prior to mediation; (2) Martin Forte v. Direct Energy (N.D.N.Y. Mar. 2017) - Direct Energy’s Motion for Summary Judgment and Plaintiff’s Class Certification are fully briefed and awaiting a ruling; (3) Richard Schafer v. Direct Energy (W.D.N.Y. Dec. 2019; on appeal 2nd Cir. N.Y.) - The trial court dismissed this action. Plaintiff appealed to the Second Circuit Court of Appeals. Oral arguments took place in April 2021. Subsequently, the Second Circuit issued a summary opinion vacating the district court's dismissal of the case. The matter was remanded back to the district court; and (4) Julie and Richard Lane v. Direct Energy (S.D.Ill. Jun. 2019) - Plaintiff has amended her Complaint in response to the Court dismissing all claims except a claim under the Illinois Consumer Protection Act. Direct Energy’s Motion to Dismiss is pending the Court’s ruling.
Telephone Consumer Protection Act ("TCPA") Cases — In the cases set forth below, referred to as the TCPA Cases, such actions involve consumers alleging violations of the Telephone Consumer Protection Act of 1991, as amended, by receiving calls, texts or voicemails without consent in violation of the federal Telemarketing Sales Rule, and/or state counterpart legislation. The underlying claims of each case are similar. The Company continues to deny the allegations asserted by plaintiffs and intends to vigorously defend these matters.
There are 2 putative class actions pending against Direct Energy: (1) Brittany Burk v. Direct Energy (S.D. Tex. Feb. 2019) - Written discovery is complete, and fact and expert discovery is ongoing. The briefing on Direct Energy’s Motion to Dismiss and Plaintiff’s Class Certification is complete; and (2) Matthew Dickson v. Direct Energy (N.D.Ohio Jan. 2018) - Direct Energy has filed a Third-Party Petition against its vendor, Total Marketing Concepts, LLC, who placed voicemails without consent from Direct Energy and in violation of the parties’ agreement. This case is stayed pending the outcome of a Second Circuit appeal of the AAPC issue. In each case, Direct Energy has filed a Motion to Dismiss for lack of subject matter jurisdiction based on the Supreme Court’s 2020 AAPC decision invalidating the TCPA provision asserted in each case.
Winter Storm Uri Lawsuits
The Company has been named in certain property damage and wrongful death claims that have been eliminatedfiled in consolidationconnection with Winter Storm Uri. At this time, the Company is unable to determine the extent or impact of these various litigation matters due to their preliminary nature. The Company intends to vigorously defend these matters.

Indemnifications and Other Contractual Arrangements
Washington-St. Tammany and Claiborne Electric Cooperative v. LaGen — On June 28, 2017, plaintiffs Washington-St. Tammany Electric Cooperative, Inc. and Claiborne Electric Cooperative, Inc. filed a lawsuit against LaGen in the United States District Court for the Middle District of Louisiana. The plaintiffs claimed breach of contract against LaGen for allegedly improperly charging the plaintiffs for costs related to the installation and maintenance of certain pollution control technology. Plaintiffs sought damages for the alleged improper charges and a declaration as to which charges were proper under the contract. In February 2020, the court dismissed this lawsuit without prejudice for lack of subject matter jurisdiction. On March 17, 2020, plaintiffs filed a lawsuit in the Nineteenth Judicial District Court for the Parish of East Baton Rouge in Louisiana alleging substantially the same matters. On February 4, 2019, NRG sold the South Central Portfolio, including the entities subject to this litigation. However, NRG has agreed to indemnify the purchaser for certain losses suffered in connection therewith.

Note 17 — Regulatory Matters
Environmental regulatory matters are discussed within Note 18, Environmental Matters.
NRG operates in a highly regulated industry and is subject to regulation by various federal, state and provincial agencies. As such, NRG is affected by regulatory developments at the federal, state and provincial levels and in the regions in which NRG operates. In addition, NRG is subject to the market rules, procedures, and protocols of the various ISO and RTO markets in which NRG participates. These power markets are subject to ongoing legislative and regulatory changes that may impact NRG's wholesale and retail operations.
In addition to the regulatory proceedings noted below, NRG and its subsidiaries are parties to other regulatory proceedings arising in the ordinary course of business or have other regulatory exposure. In management's opinion, the disposition of these ordinary course matters will not materially adversely affect NRG's consolidated financial position, results of operations, or cash flows.
California Station Power — As the result of unfavorable final and non-appealable litigation, the Company accrued a liability associated with consumption of station power at the Company's Encina power plant facility in California after August 30, 2010. The Company has established an appropriate accrual pending potential regulatory action by San Diego Gas & Electric regarding the Company's Encina facility.
South Central — On August 4, 2016, NRG received a document hold notice from FERC regarding conduct in the MISO and PJM markets. FERC Office of Enforcement Staff investigated potential violations of MISO rules involving bidding for the Big Cajun 2 facility, as well as other aspects of NRG’s operations in MISO. On August 18, 2020, FERC Office of Enforcement presented NRG with its preliminary findings. NRG responded to the preliminary findings on January 15, 2021. FERC has the authority to require disgorgement of profits and to impose penalties and NRG retains any liability following the sale of the South Central Portfolio.

Note 18 — Environmental Matters
NRG is subject to a wide range of environmental laws in the development, construction, ownership and operation of power plants. These laws generally require that governmental permits and approvals be obtained before construction and maintained during operation of power plants. The electric generation industry has been facing increasingly stringent requirements regarding air quality, GHG emissions, combustion byproducts, water discharge and use, and threatened and endangered species. In general, future laws are expected to require the addition of emissions controls or other environmental controls or to impose additional restrictions on the operations of the Company's facilities, which could have a material effect on the Company's consolidated financial position, results of operations, or cash flows. The Company has elected to use a $1 million disclosure threshold, as permitted, for environmental proceedings to which the government is a party.
Air
On July 8, 2019, the EPA promulgated the ACE rule, which rescinded the CPP, which had sought to broadly regulate CO2 emissions from the power sector. The ACE rule requires states that have coal-fired EGUs to develop plans to seek heat rate improvements from coal-fired EGUs. On January 19, 2021, the D.C. Circuit vacated the ACE rule (but on February 22, 2021, at the EPA's request, stayed the issuance of the portion of the mandate that would vacate the repeal of the CPP). Accordingly, we expect the EPA to promulgate a new rule to regulate GHG emissions from power plants.

Water
(a)Effluent Limitations Guidelines All significant intercompany transactions have been eliminated— In November 2015, the EPA revised the Effluent Limitations Guidelines ("ELG") for Steam Electric Generating Facilities, which imposed more stringent requirements (as individual permits were renewed) for wastewater streams from FGD, fly ash, bottom ash, and flue gas mercury control. On September 18, 2017, the EPA promulgated a final rule that, among other things, postponed the compliance dates to preserve the status quo for FGD wastewater and bottom ash transport water by two years to November 2020 until the EPA amended the rule. On October 13, 2020, the EPA amended the 2015 ELG rule by: (i) altering the stringency of certain limits for FGD wastewater; (ii) relaxing the zero-discharge requirement for bottom ash transport water; and (iii) changing several deadlines. The Company is in consolidationthe process of estimating the environmental capital expenditures that will be required to comply. The capital expenditures required to comply will depend on elections regarding future operations of each coal-fired unit. NRG expects to make these elections for each unit in the fourth quarter of 2021, at which time the EPA will be notified as required. Accordingly, we do not expect to provide estimates of ELG compliance costs until early 2022.
Byproducts, Wastes, Hazardous Materials and Contamination
In April 2015, the EPA finalized the rule regulating byproducts of coal combustion (e.g., ash and gypsum) as solid wastes under the RCRA. In September 2017, the EPA agreed to reconsider the rule. On July 30, 2018, the EPA promulgated a rule that amends the existing ash rule by extending some of the deadlines and providing more flexibility for compliance. On August 21, 2018, the D.C. Circuit found, among other things, that the EPA had not adequately regulated unlined ponds and legacy ponds. In 2019 and 2020, the EPA proposed several changes to this rule. On August 28, 2020, the EPA finalized "A Holistic Approach to Close Part A: Deadline to Initiate Closure," which amended the April 2015 Rule to address the August 2018 D.C. Circuit decision and extend some of the deadlines. On November 12, 2020, the EPA finalized "A Holistic Approach to Closure Part B," which further amended the April 2015 Rule to, among other things, provide procedures for requesting approval to operate existing impoundments with an alternative liner. The Company has updated its estimates of required environmental capital expenditures.

Executive Summary
Introduction and Overview
NRG Energy, Inc., or NRG or the Company, is an integrated power company built on dynamic retail brands with diverse generation assets. NRG brings the power of energy to customers by producing and selling electricity and related products and services in major competitive power and gas markets in the U.S. and Canada in a manner that delivers value to all of NRG's stakeholders. NRG is a customer-driven business focused on perfecting the integrated model by balancing retail load with generation supply within its deregulated markets. The Company sells energy, services, and innovative, sustainable products and services directly to retail customers under the brand names NRG, Reliant, Direct Energy, Green Mountain Energy, Stream, and XOOM Energy, as well as other brand names owned by NRG, supported by approximately 23,000 MW of generation, including approximately 4,850 MW of fossil generation assets held for sale as of June 30, 2020. NRG was incorporated as a Delaware corporation on May 29, 1992.
As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments from Retail and Generation to Texas, East and West/Other beginning in the first quarter of 2020. The Company's updated segment structure reflects how management currently makes financial decisions and allocates resources.

COVID-19
In March 2020, the World Health Organization categorized COVID-19 as a pandemic and the President of the United States declaredAs the COVID-19 outbreak a national emergency. Electricity was deemed a ‘critical and essential business operation’ under various state and federal governmental COVID-19 mandates.
pandemic continues, NRG continues to remainremains focused on protecting the health and well-being of its employees, while supporting its customers and the communities in which it operates and assuring the continuity of its operations. In addition, during the second quarter ofDuring 2020, NRG committed $2 millionmigrated a substantial portion of its employees to a remote work environment. The first COVID-19 relief efforts, including funding for urgently needed safety equipment supporting first responders,vaccine became available in the United States in December 2020. Vaccines have become increasingly accessible since the initial rollout and all adults across the nation became eligible to receive a vaccine as well as funds that aided local communities and teachers.of April 19, 2021. The Company also allocated additional fundingis currently planning to begin returning certain employees to the NRG Employee Relief Fundoffices through a phased approach expected to assist employees adversely impactedbe completed by natural disasters and other extraordinary events.
NRG had activated its Crisis Management Team ("CMT") in January 2020, which proactively began managing the Company's response to the impactsend of COVID-19. The CMT implemented the business continuity plans for the Company and has taken a variety of measures to ensure the ongoing availability of the Company's services, while maintaining the Company's commitment to its core values of health and safety. Pursuant to the Company's Infectious Disease & Pandemic Policy, in March 2020, NRG implemented restrictions on business travel and face-to-face sales channels, instituted remote work practices and enhanced cleaning and hygiene protocols in all of its facilities. During the second quarter of 2020, the Company began to evaluate alternatives for return to normal work operations. In addition, in order to effectively serve the Company’s customers, select essential employees and contractors are continuing to report to plant and certain office locations. The Company requires pre-entry screening, including temperature checks, separation of work crews, additional personal protective equipment for employees and contractors when social distancing cannot be maintained, and a ban on all non-essential visitors. As a result of these business continuity measures, the Company has not experienced any material disruptions in its ability to continue its business operations to date.
The Company continues to utilize the communication protocol established in January 2020, including a central information hub on its intranet, telehealth services, and its Emergency Relief Fund for financially-impacted employees.summer..
While the pandemic may present newpresents risks to the Company's business, as further described in the Company’s 2020 Form 10-K in Part II, Item 1A Risk Factors of this Form 10-Q, to the Company’s business,, there was not a material adverse impact on the Company’s 2020 results of operations for the sixthree months ended June 30, 2020.March 31, 2021. NRG believes it has sufficient liquidity on hand to continue business operations.operations in light of current circumstances posed by the pandemic. As disclosed in the Liquidity and Capital Resources section, the Company has total available liquidity of $2.2$3.2 billion as of June 30, 2020,March 31, 2021, consisting of cash on hand, and its Revolving Credit Facility.Facility, and additional facilities.
Following the President's declaration of COVID-19 outbreak being a national emergency, the Governors of the majority of states in which the Company operates issued executive orders that every person should, except where necessary to provide or obtain essential services, minimize social gatherings and minimize in-person contact with people who are not in the same household. The impact of these orders closed schools, restaurants and bars, except in certain cases for takeout, and other non-essential businesses. As state restrictions have been eased or lifted, loads have begun to recover in those markets in which the Company operates. The rebound in demand has varied across the Company's market footprint, as restrictions vary regionally. The Company expects demand uncertainty to continue in the near future.
Specifically, in Texas, the PUCT adopted the COVID-19 Electricity Relief Program (“ERP”) to mitigate the impact of COVID-19 on Texas retail electric customers experiencing economic hardship as a result of the pandemic. The COVID-19 ERP

provides temporary disconnection protection for eligible customers and establishes funds to offset some of the costs incurred by retail electric providers to continue service to those customers. Consistent with the PUCT's orders, NRG is also offering deferred payment plans to all residential and small commercial customers while the declaration of emergency in Texas is in place.
The situation surrounding COVID-19 remains fluid and the potential for a material adverse impact on the Company increases the longerexists as long as the virus impacts the level of economic activity in the United States and globally. For this reason,abroad. While the Company expects the risk to decrease as vaccinations are administered, NRG cannot reasonably estimate with any degree of certainty the full impact COVID-19, andnor any resurgence of COVID-19, may have on the Company’s results of operations, financial position, and liquidity. The extent to which the COVID-19 pandemic may impact the Company’s business, operating results, financial condition, risk exposure or liquidity will depend on future developments, including the duration of the outbreak,pandemic, travel restrictions, business and workforce disruptions, any resurgence of the outbreakpandemic and the effectiveness of actions taken to contain, mitigate and treat the disease. See Part II, Item 1A Risk Factors of this Form 10-Q.

Strategy
NRG's strategy is to maximize stockholder value through the safe production and sale of reliable power and gas to its customers in the markets served by the Company,it serves, while positioning the Company to provide innovative solutions to the end-use energy or service consumer. This strategy is intended to enable the Company to optimize the integrated model to generate stable and predictable cash flow, significantly strengthen earnings and cost competitiveness, and lower risk and volatility.

To effectuate the Company’s strategy, NRG is focused on: (i) serving the energy needs of end-use residential, commercial and industrial, and wholesale customers in competitive markets through multiple brands and channels withchannels; (ii) offering a variety of retail energy products and services, including renewable energy solutions, that are differentiated by innovative features, premium service, sustainability, and loyalty/affinity programs; (ii) offering innovative and renewable energy solutions for customers; (iii) excellence in operating performance of its existing assets; (iv) optimal hedging of NRG's net retail and generation positions;portfolio; and (v) engaging in disciplined and transparent capital allocation.
Sustainability is an integral part of NRG's strategy and ties directly to business success, reduced risks and brand value. In 2019, NRG announced the acceleration of its science-based GHG emissions reduction goals to align with prevailing climate science, limitingwhich seeks to limit global warming in the post-industrial era to a 1.5 degree Celsius increase. Under its new GHG emissions reduction timeline,degrees Celsius. NRG is targeting to achieve a 50% reduction by 2025, from its current 2014 baseline, and net-zero emissions by 2050 from a 2014 baseline.2050. The Company is on track to meet its 2025 goal.

Energy Regulatory Matters
The Company’s regulatory matters are described in the Company’s 20192020 Form 10-K in Item 1, Business — Regulatory Matters. These matters have been updated below and in Note 17, Regulatory Matters, of this Form 10-Q.Matters.
As participants in wholesale and retail energy markets and owners and operators of power plants, certain NRG entities are subject to regulation by various federal and state government agencies. These include the CFTC, FERC, NRC and the PUCT, as well as other public utility commissions in certain states where NRG's generatinggeneration or distributed generation assets are located. In addition, NRG is subject to the market rules, procedures and protocols of the various ISO and RTO markets in which it participates. Likewise, certain NRG entities participating in the retail markets are subject to rules and regulations established by the states and provinces in which NRG entities are licensed to sell at retail. NRG must also comply with the mandatory reliability requirements imposed by NERC and the regional reliability entities in the regions where NRG operates.
In March 2021, President Biden announced a framework for his "Build Back Better" initiative. The announced framework includes ideas to address climate change across the whole of the federal government through tax policy and research and development, among other areas of focus. Relatedly, the U.S. House Energy and Commerce Committee released the Climate Leadership and Environmental Action for our Nation's ("CLEAN") Future Act, which is expected to influence legislative drafts of the "Build Back Better" initiative. The CLEAN Future Act proposes, among other things, a clean electricity standard that would require electricity suppliers to procure and retire clean energy credits offsetting, in aggregate, 80% of the energy sold by 2030 and 100% by 2035. It would establish an auction-based mechanism for these credits and award partial credits to certain carbon-emitting generation that have lower-than-average emissions rates. Although these proposals have not yet resulted in any new legislation being enacted or regulations promulgated, NRG is closely monitoring both legislative and executive agency action and expects to be an active participant as proposals evolve into legislation. On April 22, 2021, the President announced that the United States' Nationally Defined Contribution to the international Paris Climate Agreement will be an economy-wide reduction in greenhouse gas emissions of 50-52% by 2030, relative to 2005 levels. No methodology to achieve those targets was announced, but legislation encompassing the "Build Back Better" initiative is expected to be the bulk of the effort, with more details expected to be announced by the November 2021 Conference of the Parties 26 meeting in Glasgow, Scotland.
NRG's operations within the ERCOT footprint are not subject to rate regulation by FERC, as they are deemed to operate solely within the ERCOT market and not in interstate commerce. These operations are subject to regulation by the PUCT, as well as to regulation by the NRC with respect to NRG's ownership interest in STP.
Federal Energy Regulation
D.C. Circuit Ruling on FERC's Use of Tolling Orders — On June 30, 2020, the U.S. Court of Appeals for the D.C. Circuit issued a decision stating that FERC's ability to "toll" actions on rehearing beyond the statutory 30-day period is unlawful. Chairman ChatterjeeState and Commissioner Glick issued a joint statement asking Congress to give FERC a reasonable amount of time to make a decision on rehearing requests under the Natural Gas Act and the Federal Power Act. This decision impacts an array of appeals related to the PJM MOPR order and will impact how rehearings are decided and appeals filed.

East/West
PJM
FERC Changes to Capacity Markets — On March 23, 2021, the Commission held its first technical conference on Resource Adequacy in the Evolving Electricity Sector to discuss the role of capacity market constructs in PJM, ISO-NE and NYISO. The technical conference included the discussion of the implications of retaining the expanded minimum offer price rule ("Expanded MOPR") in the PJM capacity market, as well as prospective alternative approaches that could replace PJM's Expanded MOPR. On April 5, 2021, the Commission issued a notice inviting post-technical conference comments seeking comments on PJM's capacity market, the implications of Expanded MOPR and potential alternatives to Expanded MOPR in PJM. The Company filed comments on April 26, 2021. Any changes to the PJM capacity market construct may impact the outcome of the Base Residual Auction to be held in December 2021 for the 2023/2024 delivery year and future auctions.
On April 22, 2021, PJM published updated Planning Period Parameters for the 2022/2023 Base Residual Auction that indicated a significant portion of Dominion zone load, presumably the Dominion Energy Virginia utility, elected the Fixed Resource Requirements ("FRR") Alternative. PJM approved the plan and adjusted the reliability requirements downward for the RTO and the respective local delivery areas. Under the existing PJM rules, an FRR election has a minimum 5-year term. Removing capacity from the auctions could impact the auction results.
Independent Market Reforms FilingMonitor Market Seller Offer Cap Complaint On December 19,February 21, 2019, the Independent Market Monitor filed a complaint alleging that the current Market Seller Offer Cap is too high. A number of parties, including PJM, filed protests to the filing arguing that, among other things, the Market Monitor failed to support its claim that the expected number of performance hours used to calculate the cap is overstated. On March 18, 2021, finding that the calculation of the default Market Seller Offer Cap was unjust and unreasonable, the Order permitted the current PJM May 2021 capacity auction for the 2022/2023 delivery rule to continue under the existing rules and set a procedural schedule for parties to file briefs with possible solutions within 45 days. As a result of this proceeding, default market caps could be lower.
Indiana Municipal Power Agency and City of Lawrenceburg, Indiana Complaint on Station Power On September 17, 2020, FERC issued an order onin response to a complaint and request for declaratory judgement challenging the pending proposalsstation power wholesale netting provisions in PJM's tariff. FERC found that it does not have jurisdiction over the supply of station power and the provision of station power is a retail sale subject to reform the PJM market to mitigate subsidized resources in the capacity market. FERC directedstate jurisdiction. The order established a Section 206 proceeding and required PJM to applysubmit a filing to show why the Minimum Offer Price Rule, or MOPR, to newstation service netting provisions of its tariff are just and existing resources receiving state subsidiesreasonable. Lawrenceburg Power, LLC filed for rehearing, which was denied by operation of law on November 19, 2020 and subject them to default offer floor prices in their capacity bids. The Order provided for various category specific exemptionsthey subsequently appealed to the MOPR, as well as a unit specific exemption, which permits any resource that can justifyUnited States Court of Appeals for the District of Columbia Circuit. The matter is pending. On November 23, 2020, PJM submitted its station power compliance filing to FERC. In an offer lower than the default offer price floor to submit such capacity bids to PJM for review. As part of the December 19, 2019 FERCApril 27, 2021 Order, FERC gave PJM 90 days to make afound that PJM's Tariff regarding station power whole netting was unjust and unreasonable, but accepted in part and rejected in part PJM's compliance filing, and submit tariff language to reflect the requirements of the Order and directedrequired PJM to include in this filing a timetable for when it proposes to hold the previously postponed Base Residual Auctions for the 2022/2023 and 2023/2024 delivery years. Multiple parties filed for rehearing and clarification. FERC ruled on April 16, 2020 to largely uphold its December 2019 Order, after which, multiple parties, including NRG, filed for appeal at various circuit courts. On March 18, 2020, PJM made its compliance filing, which among other things, stated that it would hold its next capacity auction six and a half months after a ruling on the compliance filing. Comments to the compliance filing are extended until May 15, 2020. Pursuant to the April 16, 2020 Order, PJM was required to make an additional compliance filing within 4530 days of thatthe Order. PJM made that compliance filing on June 1, 2020 and proposed to (i) hold the previously postponed Base Residual Auction for the 2022/2023 deliver year six and a half months after FERC issues an Order to (ii) hold the additional outstanding auctions four and half months after the 2022/2023 auction is held. Subjecting subsidized resources to default offer floors in the capacity market should protect the market from further price suppression. The impact of these changes on capacity markets outcomes depends on, among other factors, bidding behavior, load forecast changes, new resource entry, and existing resource exit.
New Jersey Board of Public Utilities’ Investigation on Resource Adequacy Alternatives — On March 25, 2020, the NJBPU initiated a proceeding to investigate resource adequacy alternatives for New Jersey. NRG submitted initial comments on May 20, 2020, and subsequently filed reply comments on June 24, 2020. On September 18, 2020, the NJBPU will hold a technical conference. The proceeding is pending. Any actions taken by the NJBPUThis decision could affect market prices in PJM.the rates that plants pay for station power.
New England
ISO-NE Inventoried Energy Compensation Proposal — On March 25, 2019, ISO-NE proposed an interim measure to address near-term fuel security concerns. On August 6, 2019, FERC issued a notice stating that due to lack of quorum, ISO-NE's proposal became effective by operation of law. Multiple parties filed for rehearing. Those rehearings were denied. Subsequently, multiple parties filed an appeal of FERC's Order to the Court of Appeals for the D.C. Circuit. On April 14, 2020, FERC filed a motion for a voluntary remand. On April 21, 2020, the Court of Appeals for the D.C. Circuit remanded the case back to FERC. On June 18, 2020, FERC issued an order accepting the Inventoried Energy Compensation Proposal. ISO-NE's proposal will affect future capacity market prices and the compensation that fuel secure units receive.
ISO-NE Fuel Security Improvements Proposal — On April 15, 2020, ISO-NE filed a compliance filing proposing improvements to the wholesale market design to address winter fuel security issues as directed by FERC. Multiple parties filed comments and protests. The matter is pending at FERC. The outcome of the matter will affect market prices in ISO-NE.
Mystic's Complaint on Transmission Reliability Review — On June 10, 2020, Constellation Mystic Power LLC filed a complaint at FERC against ISO-NE alleging that ISO-NE violated its Tariff in its addition of language to its planning procedure and in its conduct in carrying out a competitive transmission REPrequest for proposal to address the retirements of Mystic Units 8 and 9. NRG, through its trade associations, filed comments on June 30, 2020. The outcome of this proceeding could affect the retirement of the Mystic Units 8 and 9, thereby affecting capacity prices in ISO-NE.
Paper Hearing on ISO-NE's New Entrant Rule On July 1,August 17, 2020, FERC issued an order establishingdenying the complaint. After a Section 206 hearing initiatedrehearing that was denied by FERC'soperation of law, on January 4, 2021, Constellation Mystic Power LLC filed an appeal to the D.C. Circuit. The ISO-NE auction for the 2024-2025 delivery year concluded on February 8, 2021. Subsequently, on February 18, 2021, Constellation Mystic Power LLC withdrew the appeal.
Texas
Legislative Activity Post-Winter Storm Uri — The Texas Legislature convened extensive fact-finding hearings the week after Winter Storm Uri, and subsequently has been highly engaged in policymaking in respect to the energy sector. The focuses of the legislation pertinent to the competitive power sector include the design and governance of the ERCOT wholesale market, the weatherization of sources of power and fuel supply and related infrastructure, retail customer protections for the limited number of residential customers exposed to real-time wholesale-price index products, communications protocols before and during power outage events, and the financial security of market participants and customers including a variety of securitization proposals. The legislative session concludes at the end of May, but may reconvene in special session. A significant number of legislative proposals would direct regulatory agencies, such as the PUCT, to engage in extensive rulemaking. Due to the preliminary finding thatnature of the "new entrant rules" may be unjustlegislation and unreasonable, specifically asrulemaking process, it is unclear what, if any, impact these proposals would have on the Company or the ERCOT wholesale market.

relates to the seven-year price-lock rule. This order is a result of the D.C. Circuit February 2, 2018 remand of a FERC order regarding how generators that previously received a seven-year "price lock" should be priced in future auctions. The price-lock mechanism permits qualified new resources that clear the auction to receive their first-year clearing price for seven years. Because several auctions have been held under the existing rules, any subsequent order from FERC could affect future capacity prices in ISO-NE, as well as affect the price that non-price locked resources could receive from prior capacity auctions.
New York
New York State Public Service Commission Retail Energy Market Proceedings — On February 23, 2016, the NYSPSC issued an order referred to as the Retail Reset Order. Among other things, the Retail Reset Order placed a price cap on energy supply offers and imposed burdensome new regulations on customers. Various parties have challenged the NYSPSC's authority to regulate prices charged by competitive suppliers. On May 9, 2019 the New York Court of Appeals, the state’s highest tribunal, issued a decision affirming the NYSPSC’s authority to regulate ESCO’s prices as a condition of access to the utilities’ infrastructure. In conjunction with the court challenge, the NYSPSC also noticed an evidentiary proceeding. On December 12, 2019, the NYSPSC issued an order adopting changes to the retail access energy market based on the record in the evidentiary proceeding. The Order limits ESCO offers to three compliant products: guaranteed savings from the utility default rate, a fixed term capped at 5% of the rolling 12-month average utility default rate, or NY-sourced renewable energy that is at least 50% greater than the prevailing NY Renewable Energy Standard for load serving entities. The Order also establishes new ESCO eligibility criteria and certification process, as well as re-certification of current ESCOs. The NYSPSC ordered compliance effective February 10, 2020. On January 13, 2020, multiple parties filed motions for rehearing and a stay of the Order. On March 2, 2020, the NYSPSC issued a notice seeking comments by April 13, 2020 on the petitions for rehearing. NRG has been granted multiple extensions, resulting in the current effective date of October 9, 2020 to meet the compliance requirements for its retail products. The limited offerings imposed by the Order, as issued, may negatively impact the Company's retail sales in New York.
New York State Public Service Commission Resource Adequacy Proceeding — On August 8, 2019, the NYSPSC established an investigation into New York's resource adequacy market design. On November 8, 2019, NRG filed comments and recommendations, specifically putting forth NRG's Forward Clean Energy Market Proposal, that would allow New York to maintain a reliable system while advancing its environmental goals. The NYSPSC has engaged The Brattle Group to evaluate the multiple alternative resource adequacy structures that were recommended by the parties in the proceeding. The NYSPSC held a technical conference on July 10, 2020. The proceeding is pending. Any actions taken by the NYSPSC could affect market design and market prices in New York.
New York Buyer Side Mitigation Proceedings — On February 20, 2020, FERC issued multiple orders pertaining to the NYISO capacity market. The orders narrowed certain exemptions to buyer side mitigation measures. Specifically, FERC stated that certain renewable and self-supply resources would be exempt from offer floor mitigation but rejected NYISO’s proposal of a 1,000 MW cap on renewable resources that could qualify for the exemption. FERC ordered NYISO to make a compliance filing narrowly tailoring its cap. On April 7, 2020, NYISO submitted its compliance filing proposing a formula that sets the Renewable Exemption Limit based generally on projected load growth and generator requirements. On April 28, 2020, the generator trade association filed comments seeking clarification related to the Renewable Exemption Limit formula. On July 16, 2020, FERC accepted a large part of NYISO's April compliance filing. FERC also rejected a complaint to exempt new electric storage resources. It also rejected a blanket exemption to demand response providers currently subject to mitigation but granted a request for new demand response to receive a blanket exemption from the buyer side mitigation measures. On June 18, 2020, the NYSPSC filed petitions for review with the D.C. Circuit regarding these buyer side mitigation orders. Implementation of buyer side mitigation measures to address price suppression provides more accurate capacity price signals in the competitive market.
Texas
ORDC Reforms — In January 2019, the PUCT directed ERCOT to implement changes to its scarcity pricing structure, known as the ORDC, which is designed to increase the likelihood of scarcity pricing to support existing generation and new investment. The PUCT directed ORDC reforms to be implemented in two phases of gradually increasing magnitude. The first phase became effective on March 1, 2019 and the second phase was put into effect on March 1, 2020. To date, the ORDC reforms have produced a noticeable improvement in scarcity pricing.
Public Utility Commission of Texas’ Actions Relatedwith Respect to COVID-19 — Winter Storm Uri
On March 26, 2020,February 15, 2021, the PUCT adoptedissued an emergency order that required the COVID-19 Electricity Relief Programenergy prices of the ERCOT market to reflect the "Value of Lost Load" so long as load was being involuntary curtailed during Energy Emergency Alert 3 ("ERP"EEA3") aimed to mitigateconditions, as directed by ERCOT. This action effectively set the impactprice of COVID-19 on residential customersenergy at $9,000 per megawatt-hour for the duration of the EEA3 event. Additionally, in the competitive retail electric market who are experiencing economic hardship as a resultsame order, the PUCT temporarily suspended the Low System Wide Offer Cap ("LCAP"), reasoning that if triggered it would have the unintended effect of raising the price cap of the pandemic. The COVID-19 ERP protects residential customers deemed eligible byERCOT market above $9,000 per megawatt-hour. On February 16, 2021, the PUCT’s third party administratorPUCT largely reaffirmed its judgement, but rescinded the retroactive applicability of its February 15, 2021 order to the early hours of February 15, 2021. Consequently, energy prices remained at $9,000/MWh from disconnection for nonpayment untillate February 15, 2021 to early February 19, 2021, when ERCOT declared the end of August 2020, unless extended by the PUCT. The COVID-19 ERP also establishes anEEA3 conditions terminated.
On February 21, 2021, citing a public emergency fund to allow Retail Electric Providers ("REPs") to recover a certain amount of credit losses incurred while continuing to serve these customers. REPs may recover from the fund a proxy for a portion of their costs (at a fixed rate of $0.04 per kWh) related to

59

eligible residential customers with an unpaid, past due electric bill subject to a disconnection for non-payment notice. On March 26, 2020,and imperative public necessity, the PUCT issued an order that required REPsdirecting retail electricity providers ("REP") to suspend charginglate fees and prohibiting REPs from disconnecting residential and small commercial customers for non-payment. Although the late feesfee suspension was ended by the PUCT by order dated March 3, 2021, the PUCT has yet to lift its prohibition against disconnection.
On March 4, 2021, after the PUCT lifted its temporary suspension of the LCAP, ERCOT transitioned from using the System Wide Offer Cap ("SWCAP") to the LCAP, which resulted in the offer cap being reduced from $9,000 per MWh to $2,000 per MWh, or 50 times the Katy fuel index price for the balance of the year, whichever is greater. ERCOT makes the transition from the SWCAP to LCAP after a hypothetical gas-fired peaker, using actual power prices, would have made $315,000 MW/year (achieved on February 16, 2021), which is equal to three times the assumed net cost of new entry. The PUCT has instituted a rulemaking to fix the LCAP value at $2,000 per MWh. This transition of the offer cap may reduce the balance of year 2021 power prices due to the lower offer cap.
Since Winter Storm Uri, all three then-sitting PUCT commissions have resigned. The Governor has appointed Will McAdams and Peter Lake to the PUCT, designating the latter to become Chairman upon taking office. Messrs. McAdams and Lake were confirmed by the Texas State Senate during the week of April 19, 2021.
Regulatory and Legislative Activity on ERCOT Pricing during Winter Storm Uri — The ERCOT Independent Market Monitor ("IMM") proposed that the PUCT reprice the market such that prices during 32 hours of February 18 and 19 would not automatically be fixed at $9,000/MWh, reasoning that ERCOT had recalled all directives to transmission and distribution utilities to shed load by the late evening of February 17, 2021. The PUCT rejected this proposal. Thereafter, the Texas Senate passed SB2142 which directs the PUCT as recommended by the IMM, by March 20, 2021, to reprice the market such that prices during 32 hours of February 18 and 19 would not automatically be fixed at $9,000/MWh. The Texas House has not referred the bill and House leadership has come out publicly against the repricing. It appears Legislative members are now focused on securitization as a way to address the financial issues from Winter Storm Uri.
A number of parties have either moved the PUCT to rehear its February 15 and 16 orders, arguing that they were adopted without due process and in violation of law, or have directly appealed those orders to state court. The PUCT had until April 12, 2021 to consider the pending motions for rehearing and, not having taken action, these requests were considered denied by operation of law. Certain parties consequently filed a petition for judicial review in Travis County District Court on April 22. Separately, a party has also challenged the February 15 and 16 PUCT orders before the Court of Appeals for the Third District. Briefing in that matter has been scheduled into the summer.
ERCOT Defaults and Securitization Legislation — A number of market participants defaulted on their ERCOT transactions following Winter Storm Uri. Defaulting parties result in ERCOT short-paying other market participants that are owed net payments in the market operator's settlement process. The cumulative short pay amount as of April 30, 2021 totaled $2.992 billion. Two electric co-operatives represent 84% of this amount, with Brazos Electric Co-operative constituting an overall majority of the sum ($1.879 billion). Brazos has filed for bankruptcy protection and ERCOT is an unsecured creditor in the proceeding.
ERCOT's market protocols provide for the short pay to be extinguished through a process of uplift, whereby the cost of defaults is allocated to all market participants, including retailers, generators, municipal and co-operative utilities, and financial traders. However, the total amount of this uplift is limited by ERCOT's current protocols to $2.5 million per month. Consequently, it would take approximately 96 years for the current net short-pay balance to be uplifted to the market under the current market rules. NRG's undiscounted share of the uplift based on its current market share is estimated to be approximately $185 million and has been short-paid $83 million. The remaining $102 million has been discounted based on the 96 year repayment term and the present value of $12 million was recorded as an additional liability.
The legislature is actively considering proposals to securitize these default balances. If enacted, the PUCT would either be required or allowed to issue a financing order that authorizes the issuance of bonds, the proceeds of which would resolve the existing short pay, backed by a property right to a stream of payments by market participants of an ERCOT surcharge associated with the bonds' principal and interest. Other securitization proposals also have been introduced that specifically

permit co-operatives to securitize debts, including their ERCOT defaults, and for costs associated with online reliability deployment price adders and ancillary services to be securitized. However, the details and the scope of any securitization legislation continue to be a matter of debate at the legislature.
California
California Resource Adequacy Proceedings — Since a summer 2020 heat storm that resulted in emergency load curtailments, the State of California and CAISO have embarked on numerous new regulatory activities while redirecting existing proceedings related to the topic of resource adequacy. On March 25, 2021, the CPUC directed the state's major investor-owned utilities to engage in up to 1.5 GW of emergency procurement for 2021 and 2022. In the same docket, the CPUC approved a new demand response program for use during emergency conditions. The CPUC is also considering longer term structural reforms of the resource adequacy policy in California.
Midway-Sunset Reliability Must Run Proceeding — San Joaquin Energy, LLC, a subsidiary of NRG, owns a 50%, non-controlling interest in the Midway-Sunset Cogeneration Company ("MSCC"). MSCC owns a cogeneration facility near Fellows, California and submitted mothball notices for the cogeneration facility to the CAISO in the latter half of 2020. On December 17, 2020, the CAISO Board effectively rejected the mothball notices by authorizing its staff to designate the MSCC facility as a reliability must-run ("RMR") resource conditioned on execution of a RMR contract. In a letter dated December 16, 2020 sent to the CAISO Board, MSCC indicated that it did not object to the RMR designation but noted certain permitting and maintenance requirements for RMR operation. On January 29, 2021, MSCC made its RMR filing at FERC. Multiple parties filed protests and on March 16, 2021, MSCC filed a response to those protests. On April 2, 2021, FERC accepted the RMR filing, suspended it to become effective February 1, 2021 subject to refund and established hearing and settlement judge proceedings. The parties are engaging in settlement proceedings.
Canada
Alberta Energy Market — In December 2020, prior to its acquisition by NRG, Direct Energy filed a Non-Energy Rate Application with the Alberta Utilities Commission ("AUC") to approve cost recovery for the 2020-2022 period. Major cost elements of this application relate to bad debt, corporate costs, and customer care and billing contracts. The Company engaged in a mediation and settlement process, and on April 20, 2021 an all-party settlement was executed, and was filed with the AUC on April 23, 2021. The Company expects an AUC decision approving the settlement agreement this year. Separately, the Company received approval from the AUC of a negotiated rate settlement for its electricity focused 2020-2022 Energy Price Setting Plan. The Company is also in the process of repaying the remainder of amounts advanced to it from the Balance Pool and the Alberta government as part of its 90 day utility bill deferral program. This program, effective March 18, 2020, was designed to assist residential, farms, and small business customers who were negatively affected by COVID-19 related economic circumstances by temporarily deferring their utility bill payments. The program was also designed to mitigate bad debt risks associated with the response to the Governor's disaster declaration relating to COVID-19. On April 17, 2020, the PUCT narrowed the scopeimplementation of the late fees waiver to just residential customers. The late fees waiver ended on May 15, 2020.
CAISO
Resource Adequacy Central Procurement Proceeding — On March 26, 2020, a CPUC Administrative Law Judge issued a proposed decision adopting implementation details for the central procurement of multi-year local resource adequacy capacity to begin for the 2023 compliance year for the PG&E and Southern California Edison ("SCE") service areas, under which PG&E and SCE would be the respective central procurement entities. The March 26, 2020 proposed decision declined to adopt a central procurement framework for the San Diego Gas and Electric service area and rejected a proposed settlement filed by various entities including NRG, which included the expansion of multi-year requirements to all categories of resource adequacy (system, flexible and local) and a residual procurement model for the central procurement entity. NRG submitted comments opposing the proposed decision on April 15, 2020. On June 11, 2020, the CPUC adopted the decision mandating the central procurement of multi-year local resource adequacy capacity to begin for the 2023 compliance year for PG&E and SCE service areas. The CPUC also rejected the proposed settlement filed by various entities, including NRG. The CPUC decision represents a retreat from market-based solutions ensuring reliable capacity in California.program.

Environmental Regulatory Matters
NRG is subject to numerous environmental laws in the development, construction, ownership and operation of power plants. These laws generally require that governmental permits and approvals be obtained before construction and maintained during operation of power plants. Federal and state environmental laws historically have become more stringent over time. Future laws may require the addition of emissions controls or other environmental controls or impose restrictions on the Company's operations. Complying with environmental laws often involves specialized human resources and significant capital and operating expenses, as well as occasionally curtailing operations. The COVID-19 pandemic may prevent the Company from complying with certain of its environmental requirements, which federal and state regulators have recognized. NRG decides to invest capital for environmental controls based on the relative certainty of the requirements, an evaluation of compliance options, and the expected economic returns on capital.
A number of regulations that may affect the Company are under reviewhave been revised recently by the EPA, including ash storage and disposal requirements, NAAQS revisions and implementation and effluent limitation guidelines. Some of these recent revisions may, in turn, be revised by the new U.S. presidential administration. NRG will evaluate the impact of these regulations as they are revised but cannot fully predict the impact of each until anticipated revisions and legal challenges are resolved. The Company’s environmental matters are described in the Company’s 20192020 Form 10-K in Item 1, Business - Environmental Matters and Item 1A, Risk Factors. These matters have been updated in Note 18, Environmental Matters, to the Condensed Consolidated Financial Statementscondensed consolidated financial statements of this Form 10-Q and as follows.
Air 
The CAA and the resulting regulations (as well as similar state and local requirements) have the potential to affect air emissions, operating practices and pollution control equipment required at power plants. Under the CAA, the EPA sets NAAQS for certain pollutants including SO2, ozone, and PM2.5. Many of the Company's facilities are located in or near areas that are

40


classified by the EPA as not achieving certain NAAQS (non-attainment areas). The relevant NAAQS havemay become more stringent. The Company maintains a comprehensive compliance strategy to address continuing and new requirements. Complying with increasingly stringent air regulations could require the installation of additional emissions control equipment at some NRG facilities or retiring of units if installing such controls is not economic. Significant changes to air regulatory programs affecting the Company are described below.
Clean Power PlanCPP/ACE Rules — The attention in recent years on GHG emissions has resulted in federal regulations and state legislative and regulatory action.regulations. In October 2015, the EPA finalizedpromulgated the CPP, addressing GHG emissions from existing EGUs. On February 9, 2016, the U.S. Supreme Court stayed the CPP. In July 2019, EPA promulgated the ACE rule, which rescinded the CPP, which had sought to broadly regulate CO2 emissions from the power sector. The ACE rule requires states that have coal-fired EGUs to develop plans to seek heat rate improvements from coal-fired EGUs. Texas, Illinois and Delaware have started working on plans to comply withOn January 19, 2021, the ACE rule. Numerous parties have challengedD.C. Circuit vacated the ACE rule in(but on February 22, 2021, at the D.C. Circuit and numerous parties have filed petitions for reconsideration withEPA's request, stayed the EPA.issuance of the portion of the mandate that would vacate the repeal of the CPP). Accordingly, we expect the EPA to promulgate a new rule to regulate GHG emissions from power plants.
 Byproducts, Wastes, Hazardous Materials and Contamination
In April 2015, the EPA finalized the rule regulating byproducts of coal combustion (e.g., ash and gypsum) as solid wastes under the RCRA. In September 2017, the EPA agreed to reconsider the rule. On July 30, 2018, the EPA promulgated a rule that amends the existing ash rule by extending some of the deadlines and providing more flexibility for compliance. On August 21, 2018, the D.C. Circuit found, among other things, that the EPA had not adequately regulated unlined ponds and legacy ponds.

60

On August 14, In 2019 the EPA proposed targeted changes to the April 2015 Rule including changes to address the August 2018 D.C. Circuit decision. On December 2, 2019, the EPA released for comment "Closure Part A Proposal" to revise the CCR Rule to address the D.C. Circuit's 2018 decision regarding the adequacy of clay-lined impoundments, obligations to close all unlined impoundments and related deadlines. On February 20, 2020, the EPA proposed the framework for developing and implementing a federal permit program for states that are not approvedseveral changes to administer the CCRthis rule. On March 3,August 28, 2020, the EPA proposed for comment "A Holistic Approach to Closure Part B," which proposes procedures for obtaining approval to operate existing impoundments with alternative liners. On July 29, 2020, the EPA released a prepublication (non-official) version of the final rulefinalized "A Holistic Approach to Closure Part A: Deadline to Initiate Closure," which when published in the Federal Register will amendamended the April 2015 Rule to address the August 2018 D.C. Circuit decision and extend some of the deadlines. On November 12, 2020, the EPA finalized "A Holistic Approach to Closure Part B: Alternative Demonstration for Unlined Surface Impoundments," which further amended the April 2015 Rule to, among other things, provide procedures for requesting approval to operate existing ash impoundments with an alternate liner. The Company anticipates that the EPA will promulgate additional regulations to further amend the existing rule. The Company will updatehas updated its estimates of required environmental capital expenditures as the rule is revised.to address this revised rule.
Domestic Site Remediation Matters
Under certain federal, state and local environmental laws, a current or previous owner or operator of a facility, including an electric generating facility, may be required to investigate and remediate releases or threatened releases of hazardous or toxic substances or petroleum products. NRG may be responsible for property damage, personal injury and investigation and remediation costs incurred by a party in connection with hazardous material releases or threatened releases. These laws impose liability without regard to whether the owner knew of or caused the presence of the hazardous substances, and the courts have interpreted liability under such laws to be strict (without fault) and joint and several. Cleanup obligations can often be triggered during the closure or decommissioning of a facility, in addition to spills during its operations. Further discussions of affected NRG sites can be found in Note 16, Commitments and Contingencies, to the Condensed Consolidated Financial Statements.condensed consolidated financial statements.
Nuclear Waste — The federal government's program to construct a nuclear waste repository at Yucca Mountain, Nevada was discontinued in 2010. Since 1998, the U.S. DOE has been in default of the federal government's obligations to begin accepting spent nuclear fuel, or SNF, and high-level radioactive waste, or HLW, under the Nuclear Waste Policy Act. Owners of nuclear plants, including the owners of STP, had been required to enter into contracts setting out the obligations of the owners and the U.S. DOE, including the fees to be paid by the owners for the U.S. DOE's services to license a spent fuel repository. Effective May 16, 2014, the U.S. DOE stopped collecting the fees.
On February 5, 2013, STPNOC entered into a settlement agreement with the U.S. DOE for payment of damages relating to the U.S. DOE's failure to accept SNF and HLW under the Nuclear Waste Policy Act through December 31, 2013, which has been extended twicethree times through addendums to cover payments through December 31, 2019. The Department of Justice has proposed to extend the existing settlement for three additional years through December 31, 2022. STPNOC has agreed to this proposal and steps to obtain approval of the settlement by the authorized representative of the Attorney General are in progress. There are no facilities for the reprocessing or permanent disposal of SNF currently in operation in the U.S., nor has the NRC licensed any such facilities. STPNOC currently stores all SNF generated by its nuclear generating facilities on-site. STPNOC plans to continue to assert claims against the U.S. DOE for damages relating to the U.S. DOE's failure to accept SNF and HLW.
Under the federal Low-Level Radioactive Waste Policy Act of 1980, as amended in 1985, the state of Texas is required to provide, either on its own or jointly with other states in a compact, for the disposal of all low-level radioactive waste generated within the state. Texas is currently in a compact with the state of Vermont, and the compact low-level waste facility located in Andrews County in Texas has been operational since 2012.
Water 
The Company is required under the CWA to comply with intake and discharge requirements, requirements for technological controls and operating practices. As with air quality regulations, federal and state water regulations have become more stringent and imposed new requirements.
Effluent Limitations Guidelines — In November 2015, the EPA revised the Effluent Limitations Guidelines for Steam Electric Generating Facilities, which would have imposed more stringent requirements (as individual permits were renewed) for wastewater

streams from FGD, fly ash, bottom ash, and flue gas mercury control. On September 18, 2017, the EPA promulgated a final rule that, among other things, postponespostponed the compliance dates to preserve the status quo for FGD wastewater and bottom ash transport water by two years to November 2020 until the EPA completes its next rulemaking.amended the rule. On April 12, 2019, the United States Court of Appeals for the Fifth circuit addressed challenges to the rule brought by several environmental groups related to legacy wastewaters and coal ash leachate and remanded portions of the rule to the EPA. On November 22, 2019,October 13, 2020, the EPA proposed amendingamended the 2015 ELG rule by: (x) decreasing(i) altering the stringency of the selenium limit (but increasing the stringency of the nitrate and mercury limits)certain limits for FGD wastewater; (y)(ii) relaxing the zero-discharge requirement for bottom ash transport water; and (z)(iii) changing several deadlines.

NRG expects to make these estimates afterelections for each unit in the fourth quarter of 2021 at which time the EPA revises the rule andwill be notified as permits are renewed.required. Accordingly, we do not expect to provide estimates of ELG compliance costs until early 2022.

Regional Environmental Developments
NY NOx — On December 31, 2019, the New York State Department of Environmental Conservation finalized a more stringent NOx regulation that will result in the retirement of the Company's combustion turbines in Astoria, New York in 2023.
Ash Regulation in Illinois — On July 30, 2019, Illinois enacted legislation that will requirerequires the state to promulgate regulations regarding coal ash at surface impoundments. On March 30, 2020,April 15, 2021, the state releasedpromulgated the implementing regulation, which became effective on April 21, 2021. The new regulation requires NRG to apply for initial operating permits for its proposed implementing regulations. The Company expects the state to promulgate the final implementing regulationscoal ash surface impoundments by October 31, 2021 and construction permits (for closure) starting in March 2021, at which time regulated entities will then prepare and submit permit applications.2022.

Significant Events
The following significant events have occurred during 20202021 as further described within this Management's Discussion and Analysis and the Condensed Consolidated Financial Statements:condensed consolidated financial statements:
Extreme Weather Event in Texas During February 2021
During February 2021, Texas experienced unprecedented cold temperatures for a prolonged duration, resulting in a power emergency, blackouts, and an estimated all-time peak demand of 77 GW (without load shed). Ahead of the event, NRG launched residential customer communications calling for conservation across all of its brands, and initiated residential and commercial and industrial demand response programs to curtail customer load. The Company maximized available generating capacity and brought in additional resources to supplement in-state staff with technical and operating experts from the rest of its U.S. fleet.
During the quarter ended March 31, 2021, Winter Storm Uri's financial impact to loss before income taxes was a loss of $967 million. A number of factors may mitigate or increase the financial impact, such as recently proposed regulatory securitization packages, finalizing meter and settlement data, potential customer and counterparty risk including ERCOT's shortfall payments and uplift charges, and one-time cost savings.
Direct Energy Acquisition
On July 24, 2020,January 5, 2021, the Company entered into a definitive purchase agreement with Centrica to acquireacquired Direct Energy, a North American subsidiary of Centrica (the "Purchase Agreement").Centrica. Direct Energy is a leading retail provider of electricity, natural gas, and home and business energy related products and services in North America, with operations in all 50 U.S. states and 68 Canadian provinces. The acquisition will addincreases NRG's retail portfolio by over 3 million customers to NRG's business and build on and complementcomplements its integrated model, enabling better matching of power generation with customer demand.model.

Sale of 4.8 GW of Fossil Generation Assets
On February 28, 2021, the Company entered into a definitive purchase agreement with Generation Bridge, an affiliate of ArcLight Capital Partners, to sell approximately 4,850 MW of fossil generating assets from its East and West regions of operations for total proceeds of $760 million, subject to standard purchase price adjustments and certain other indemnifications. As part of the transaction, NRG is entering into a tolling agreement for its 866 MW Arthur Kill plant in New York City through April 2025.
The acquisitiontransaction is expected to close in the fourth quarter of 2021, and is subject to approval by the shareholders of Centrica, as well as customaryvarious closing conditions, approvals and consents, including FERC, NYSPSC, and regulatory approvals, including the expiration or termination of the applicable waiting periodantitrust review under the HSR Act, and the receipt of approvals or expiration of applicable waiting periods under the Federal Power Act and the Canadian CompetitionHart-Scott-Rodino Act.
The acquisition is targeted to close by December 31, 2020. There are no assurances that the conditions to the consummation of the acquisition of Direct Energy will be satisfied, that Centrica will not seek or enter into an alternative transaction, or that the acquisition of Direct Energy will be consummated on the terms agreed to, or at all.
Share Repurchases
During the six months ended June 30, 2020, the Company completed $224 million of share repurchases at an average price of $33.05 per share, including $27 million of equivalent shares purchased in lieu of tax withholdings on equity compensation issuance.
Renewable Power Purchase Agreements
During 2019, NRG began execution of itsThe Company's strategy is to procure mid to long-term generation through renewable power purchase agreements. As of June 30, 2020,March 31, 2021, NRG has entered into PPAs totaling approximately 1,600 MWs2.2 GW with third-party project developers and other counterparties. The tenor of these agreements is an average of elevenbetween twelve and thirteen years. The Company expects to continue evaluating and executing similar agreements that support the needs of the business.

    Total gross margin(361)

    Total impact to loss before income taxes$(967)
A number of factors may mitigate or increase the financial impact, such as recently proposed regulatory securitization packages, finalizing meter and settlement data, potential customer and counterparty risk including ERCOT's shortfall payments and uplift charges, and one-time cost savings.
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, other costs of sales, 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 the sum of energy revenue, capacity revenue, retail revenue and other revenue, less cost of fuels and other cost of sales. Economic gross margin does not include mark-to-market gains or losses on economic hedging activities, contract amortization, emission credit amortization, or other operating costs.

Interest ExpenseGross Margin
Interest expense decreasedThe Company calculates gross margin in order to evaluate operating performance as operating revenues less cost of sales, which includes cost of fuel, other costs of sales, 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 $9 millionthe Company's chief operating decision maker. Economic gross margin is defined as the sum of energy revenue, capacity revenue, retail revenue and other revenue, less cost of fuels and other cost of sales. Economic gross margin does not include mark-to-market gains or losses on economic hedging activities, contract amortization, emission credit amortization, or other operating costs.

Mark-to-market results consist of unrealized gains and losses on contracts that are not yet settled. The settlement of these transactions is reflected in the same revenue or cost caption as the items being hedged.
For the three months ended March 31, 2021, the $32 million loss in operating revenues from economic hedge positions was driven primarily by the reversal of previously recognized unrealized gains on contracts that settled during the period as well as a decrease in the value of open positions as a result of increases in West power prices. The $753 million gain in operating costs and expenses from economic hedge positions was driven primarily by an increase in the value of open positions as a result of increases in ERCOT power prices and ERCOT heat rate expansion, as well as the reversal of acquired deals and previously recognized unrealized losses on contracts that settled during the period.
For the three months ended March 31, 2020, the $4 million loss in operating revenues from economic hedge positions was driven primarily by the reversal of previously recognized unrealized gains on contracts that settled during the period, largely offset by an increase in the value of open positions, as a result of gains on power positions due to declines in West/Services/Other power prices. The $48 million gain in operating costs and expenses from economic hedge positions was driven primarily by the reversal of previously recognized unrealized losses on contracts that settled during the period, as well as gains on ERCOT heat rate positions due to heat rate expansion.

Impairment losses on investments
Impairment losses on investments of $18 million were recorded during the three months ended March 31, 2020 related to the impairment of Petra Nova Parish Holdings, as further discussed in Note 8, Impairments.
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, other costs of sales, 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 the sum of energy revenue, capacity revenue, retail revenue and other revenue, less cost of fuels and other cost of sales. Economic gross margin does not include mark-to-market gains or losses on economic hedging activities, contract amortization, emission credit amortization, or other operating costs.

Mark-to-market results consist of unrealized gains and losses on contracts that are not yet settled. The settlement of these transactions is reflected in the same revenue or cost caption as the items being hedged.

As of December 31, 2019,2020, the Company had cumulative domestic Federal NOL carryforwards of $10.1 billion, which will begin expiring in 2031, and cumulative state NOL carryforwards of $5.5$5.4 billion for financial statement purposes. NRG also has cumulative foreign NOL carryforwards of $357$347 million, which do not have an expiration date. In addition to the above NOLs, NRG has a $14 million indefinite carryforward for interest deductions, as well as $384 million of tax credits to be utilized in future years. As a result of the Company's tax position, and based on current forecasts, NRG anticipates income tax payments, primarily to state and localforeign jurisdictions, of up to $18$60 million in 2020.2021.
TheAs of March 31, 2021, the Company has $23 million of tax-effected uncertain federal and state tax benefits, for which the Company has recorded a non-current tax liability of $18 million, inclusive(inclusive of accrued interest, for uncertain tax benefits taken on various state income tax positionsinterest) until final resolution is reached with the related taxing authority.
The Company is no longer subject to U.S. federal income tax examinations for years prior to 2016.2017. With few exceptions, state and local income tax examinations are no longer open for years prior to 2011.2012.
Deferred tax assets and valuation allowance
Net deferred tax balance As of both June 30, 2020March 31, 2021 and December 31, 2019,2020, NRG recorded a net deferred tax asset, excluding valuation allowance, of $3.4 billion.$2.9 billion and $3.3 billion, respectively. The Company believes certain state net operating losses may not be realizable under the more-likely-than-not measurement and as such, a valuation allowance was recorded as of June 30, 2020March 31, 2021 as discussed below.
Valuation allowanceNOL Carryforwards As of June 30, 2020March 31, 2021, the Company had a tax-effected cumulative U.S. NOLs consisting of carryforwards for federal and state income tax purposes of $2.1 billion and $456 million, respectively. The Company estimates it will need to generate future taxable income to fully realize the net federal deferred tax asset before the expiration of certain carryforwards commences in 2031. In addition, NRG has tax-effected cumulative foreign NOL carryforwards of $102 million with no expiration date.
Valuation Allowance – As of March 31, 2021 and December 31, 2019,2020, the Company'sCompany’s tax-effected valuation allowance was $241$266 million, and $242 million, respectively, consisting of state NOL carryforwards and foreign NOL carryforwards. The valuation allowance was recorded based on the assessment of cumulative and forecasted pre-tax book earnings and the future reversal of existing taxable temporary differences.

Off-Balance Sheet Arrangements
Obligations under Certain Guarantee Contracts
NRG and certain of its subsidiaries enter into guarantee arrangements in the normal course of business to facilitate market transactions with third parties. These arrangements include financial and performance guarantees, stand-by letters of credit, debt guarantees, surety bonds and indemnifications.
The Company disclosed its Guarantees in Note 28, Guarantees, to the Company's 2020 Form 10-K. As of March 31, 2021, NRG and its consolidated subsidiaries were contingently obligated for a total of $2.8 billion under letters of credit and surety bonds, compared to $1.2 billion as of December 31, 2020. The increase is primarily due to the acquisition of Direct Energy in January 2021. Most of these letters of credit and surety bonds are issued in support of the Company's obligations to perform under commodity agreements and obligations associated with future closure and maintenance of ash sites, as well as for financing or other arrangements. A majority of these letters of credit and surety bonds expire within one year of issuance, and it is typical for the Company to renew them on similar terms.

Retained or Contingent Interests
NRG 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 June 30, 2020,March 31, 2021, NRG has investments in energy and energy-related entities that are accounted for under the equity method of accounting. NRG’s investment in Ivanpah is a variable interest entity for which NRG is not the primary beneficiary. See also Note 10, Investments Accounted for Using the Equity Method and Variable Interest Entities, or VIEs to this Form 10-Q..

86

NRG's pro-rata share of non-recourse debt held by unconsolidated affiliates was approximately $859$567 million as of June 30, 2020.March 31, 2021. This indebtedness may restrict the ability of these subsidiaries to issue dividends or distributions to NRG. See also Note 15, Investments Accounted for by the Equity Method and Variable Interest Entities, to the Company's 20192020 Form 10-K.
Contractual Obligations and Market Commitments
NRG has a variety of contractual obligations and other market commitments that represent prospective cash requirements in addition to the Company's capital expenditure programs, as disclosed in the Company's 20192020 Form 10-K. See also Note 9, Long-term Debt and Finance Leases, and Note 16, Commitments and Contingencies, to this Form 10-Q for a discussion of new commitments and contingencies that also include contractual obligations and market commitments that occurred during the three and six months ended June 30, 2020.March 31, 2021.

Guarantor Financial Information
As of March 31, 2021, the Company had outstanding $5.9 billion of Senior Notes and Convertible Senior Notes due 2026 to 2048, outstanding $2.5 billion of Senior Secured First Lien Notes due from 2024 to 2029 and outstanding $466 million of tax-exempt bonds as shown in Note 9, Long-term Debt and Finance Leases. These Senior Notes, Senior Secured First Lien Notes and tax-exempt bonds are guaranteed by certain of NRG's current and future 100% owned domestic subsidiaries, or guarantor subsidiaries (the “Guarantors”). See Exhibit 22.1 for a listing of the Guarantors. These guarantees are both joint and several.
NRG conducts much of its business through and derives much of its income from its subsidiaries. Therefore, the Company's ability to make required payments with respect to its indebtedness and other obligations depends on the financial results and condition of its subsidiaries and NRG's ability to receive funds from its subsidiaries. There are no restrictions on the ability of any of the Guarantors to transfer funds to NRG. Other subsidiaries of the Company do not guarantee the registered debt securities of either NRG Energy, Inc or the Guarantors (such subsidiaries are referred to as the “Non-Guarantors”). The Non-Guarantors include all of NRG's foreign subsidiaries and certain domestic subsidiaries.
The tables below present summarized financial information of NRG Energy, Inc. and the Guarantors in accordance with Rule 3-10 under the SEC's Regulation S-X. The financial information may not necessarily be indicative of results of operations or financial position of NRG Energy, Inc. and the Guarantors in accordance with U.S. GAAP.

Fair Value of Derivative Instruments
NRG may enter into power purchase and sales contracts, fuel purchase contracts and other energy-related financial instruments to mitigate variability in earnings due to fluctuations in spot market prices and to hedge fuel requirements at power plants or retail load obligations. Historically,In addition, in order to mitigate interestforeign exchange rate risk associated with the issuancepurchase of USD denominated natural gas for the Company's variable rateCanadian business, NRG enters into foreign exchange contract agreements.
NRG's trading activities are subject to limits in accordance with the Company's Risk Management Policy. These contracts are recognized on the balance sheet at fair value and fixed rate debt, NRG entered into interest rate swap agreements. As of June 30, 2020, NRG had no interest rate derivative instruments. The following disclosures aboutchanges in the fair value of these derivative financial instruments provide an update to, and should be readare recognized in conjunction with, Fair Value of Derivative Instruments in Item 7 — Management's Discussion and Analysis of Financial Condition and Results of Operations, of the Company's 2019 Form 10-K.earnings.

The Company has elected to presentdisclose derivative assets and liabilities on a trade-by-trade basis and does not offset amounts at the counterparty master agreement level. Also, collateral received or paidposted on the Company's derivative assets or liabilities are recorded on a separate line item on the balance sheet. Consequently, the magnitude of the changes in individual current and non-current derivative assets or liabilities is higher than the underlying credit and market risk of the Company's portfolio. As discussed in Item 3, Quantitative and Qualitative Disclosures About Market Risk Commodity Price Risk, to this Form 10-Q, NRG measures the sensitivity of the Company's 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 Company's net open position. As the Company's trade-by-trade derivative accounting results in a gross-up of the Company's derivative assets and liabilities, the net derivative asset and liability position is a better indicator of NRG's hedging activity. As of June 30, 2020,March 31, 2021, NRG's net derivative asset was $203$384 million, an increase to total fair value of $136$447 million as compared to December 31, 2019.2020. This increase was primarily driven by gains in fair value as well asand roll-off of trades that settled during the period, partially offset by Direct Energy contracts acquired during the period.

Based on a sensitivity analysis using simplified assumptions, the impact of a $0.50 per MMBtu increase in natural gas prices across the term of the derivative contracts would result in an increase of approximately $166 million$1.309 billion in the net value of derivatives as of June 30, 2020. March 31, 2021.
The impact of a $0.50 per MMBtu decrease in natural gas prices across the term of derivative contracts would result in a decrease of approximately $167 million$1.337 billion in the net value of derivatives as of June 30, 2020.March 31, 2021.

Critical Accounting Policies and Estimates
NRG's discussion and analysis of the financial condition and results of operations are based upon the Condensed Consolidated Financial Statements,condensed 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 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 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, NRG 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 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 require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain. NRG's critical accounting policies include derivative instruments, income taxes and valuation allowance for deferred tax assets, impairment of long-lived assets and investments, goodwill and other intangible assets, and contingencies.
The Company's significant accounting policies are outlined in Note 2, Summary of Significant Accounting Policies, of this Form 10-Q, and in Note 2, Summary of Significant Accounting Policies, under Part IV, Item 15 of the Company's 20192020 Form 10-K. The Company's critical accounting estimates are described in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, in the Company's 20192020 Form 10-K. There have been no material changes to the Company's critical accounting policies and estimates since the 20192020 Form 10-K, except as noted below.
As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments to Texas, East and West/Other beginning in the first quarter of 2020, as further described in Note 1, Nature of Business. As a result, the Company identified its reporting units as Texas (included in the Texas segment), East Retail (included in the East segment) and Midwest Generation (included in the East segment). The Company performed a quantitative assessment, using primarily an income approach, for each of the Company's new reporting units as of January 1, 2020. Under the income approach, the Company estimated the fair value of each reporting unit's cash flow exceeded its carrying value and, as such, the Company concluded that goodwill associated with each of the reporting units was not impaired as of January 1, 2020 as a result of the change in reporting units.10-K.

ITEM 3 — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
NRG is exposed to several market risks in the Company's normal business activities. Market risk is the potential loss that may result from market changes associated with the Company's merchant power generation or with an existing or forecasted financial or commodity transaction.transactions. The types of market risks the Company is exposed to are commodity price risk, liquidity risk, credit risk, interest rate risk and currency exchange risk. The following disclosures about market risk provide an update to, and should be read in conjunction with, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, of the Company's 20192020 Form 10-K.
Commodity Price Risk
Commodity price risks result from exposures to changes in spot prices, forward prices, volatilities and correlations between various commodities, such as natural gas, electricity, coal, oil and emissions credits. NRG manages the commodity price risk of the Company's merchant generation operations and load serving obligations by entering into various derivative or non-derivative instruments to hedge the variability in future cash flows from forecasted sales and purchases of electricity and fuel. NRG measures the risk of the Company's portfolio using several analytical methods, including sensitivity tests, scenario tests, stress tests, position reports and VaR. NRG uses a Monte Carlo simulation based VaR model to estimate the potential loss in the fair value of its energy assets and liabilities, which includes generation assets, gas transportation and storage assets, load obligations and bilateral physical and financial transactions.transactions, based on historical and forward values for factors such as customer demand, weather and commodity prices. The Company's VaR model is based on a one-day holding period at a 95% confidence interval for the forward 36 months, not including the spot month. The VaR model is not a complete picture of all risks that may affect the Company's results. Certain events such as counterparty defaults, regulatory changes, and extreme weather and prices that deviate significantly from historically observed values are not reflected in the model.
The following table summarizes average, maximum and minimum VaR for NRG's commodity portfolio, including generation assets, load obligations and bilateral physical and financial transactions, calculated using the VaR model for the three and six months ending June 30, 2020March 31, 2021 and 2019:2020:

In order to provide additional information, the Company also uses VaR to estimate the potential loss of derivative financial instruments that are subject to mark-to-market accounting. These derivative instruments include transactions that were entered into for both asset management and trading purposes. The VaR for the derivative financial instruments calculated using the diversified VaR model for the entire term of these instruments entered into for both asset management and trading, was $15$94 million, as of June 30, 2020,March 31, 2021, primarily driven by asset-backed and hedging transactions. The increase in the VaR for derivative financial instruments was primarily due to the acquisition of Direct Energy.
Liquidity Risk
Liquidity risk arises from the general funding needs of the Company's activities and in the management of the Company's assets and liabilities. The Company is currently exposed to additional collateral posting if natural gas prices decline, primarily due to the long natural gas equivalent position at various exchanges used to hedge NRG's retail supply load obligations.
Based on a sensitivity analysis for power and gas positions under marginable contracts as of June 30, 2020,March 31, 2021, a $0.50 per MMBtu decrease in natural gas prices across the term of the marginable contracts would cause an increase in margin collateral posted of approximately $180$1,009 million and a 1.00 MMBtu/MWh decrease in heat rates for heat rate positions would result in an increase in margin collateral posted of approximately $46$345 million. This analysis uses simplified assumptions and is calculated based on portfolio composition and margin-related contract provisions as of June 30, 2020.March 31, 2021.

62


Credit Risk
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. NRG is exposed to counterparty credit risk through various activities including wholesale sales, fuel purchases and retail supply arrangements, and retail customer credit risk through its retail load activities. See Note 5, Fair Value of Financial Instruments, to this Form 10-Q for discussions regarding counterparty credit risk and retail customer credit risk, and Note 7, Accounting for Derivative Instruments and Hedging Activities, to this Form 10-Q for discussion regarding credit risk contingent features.

89

Interest Rate Risk
NRG was previously exposed to fluctuations in interest rates through its issuance of variable rate debt. Exposures to interest rate fluctuations may be mitigated by entering into derivative instruments known as interest rate swaps, caps, collars and put or call options. These contracts reduce exposure to interest rate volatility and result in primarily fixed rate debt obligations when taking into account the combination of the variable rate debt and the interest rate derivative instrument. NRG's risk management policies allow the Company to reduce interest rate exposure from variable rate debt obligations.
The Company previously entered into interest rate swaps. As of June 30, 2020, NRG had no interest rate derivative instruments.
As of June 30, 2020,March 31, 2021, the fair value and related carrying value of the Company's debt was $6.2$10 billion and $5.9$9.6 billion respectively. NRG estimates that a 1% decrease in market interest rates would have increased the fair value of the Company's long-term debt as of June 30, 2020March 31, 2021 by $510$718 million.
Currency Exchange Risk
NRG's foreign earnings and investments may beNRG is subject to transactional exchange rate risk from transactions with customers in countries outside of the United States, primarily within Canada, as well as from intercompany transactions between affiliates. Transactional exchange rate risk arises from the purchase and sale of goods and services in currencies other than our functional currency or the functional currency of an applicable subsidiary. NRG hedges a portion of its forecasted currency transactions with foreign exchange forward contracts. As of March 31, 2021, NRG is exposed to changes in foreign currency associated with the purchase of U.S.dollar denominated natural gas for its Canadian business and entered into foreign exchange contracts with notional amount of $158 million.
The Company is subject to translation exchange rate risk which NRG generally doesrelated to the translation of the financial statements of its foreign operations into U.S. dollars. Costs incurred and sales recorded by subsidiaries operating outside of the United States are translated into U.S. dollars using exchange rates effective during the respective period. As a result, the Company is exposed to movements in the exchange rates of various currencies against the U.S. dollar, primarily the Canadian and Australian dollars. A 10% depreciation or appreciation in major currencies relative to the U.S. dollar as of March 31, 2021 would not hedge. As these earnings and investments are nothave resulted in a material to NRG's consolidated results,difference within the Company's foreign currency exposure is limited.Consolidated Statement of Operations.

ITEM 1 — LEGAL PROCEEDINGS
For a discussion of material legal proceedings in which NRG was involved through June 30, 2020,March 31, 2021, see Note 16, Commitments and Contingencies, to this Form 10-Q.

ITEM 1A — RISK FACTORS
Except as set forth below, duringDuring the sixthree months ended June 30, 2020,March 31, 2021, there were no material changes to the Risk Factors disclosed in Part I, Item 1A, Risk Factors, of the Company's 20192020 Form 10-K.
Public health threats or outbreaks of communicable diseases could have a material adverse effect on the Company’s operations and financial results.
The Company may face risks related to public health threats or outbreaks of communicable diseases. A widespread healthcare crisis, such as an outbreak of a communicable disease, could adversely affect the global economy and the Company’s ability to conduct its business for an indefinite period of time. For example, the ongoing global COVID-19 pandemic has negatively impacted local and global economies, disrupted financial markets and international trade, resulted in increased unemployment levels and impacted local and global supply chains, all of which negatively impact the electricity industry and the Company’s business. In addition, federal, state, and local governments have implemented various mitigation measures, including travel restrictions, border closings, restrictions on public gatherings, shelter-in-place orders and limitations on business activities. Although the operations of the Company are considered an essential service, some of these measures have adversely impacted the ability of NRG employees, contractors, suppliers, customers, and other business partners to conduct business activities. This could have a material adverse effect on the Company’s results of operations, financial condition, risk exposure and liquidity.
In particular, the continued spread of COVID-19 and efforts to contain the virus could:
adversely impact demand for the Company’s electricity services and other products and services and the ability of customers to pay their bills;
cause an increase in costs for the Company as a result of emergency measures taken by state and local regulatory authorities in response to the COVID-19 crisis, including regulatory changes prohibiting customer disconnects and late fees;
impact the ability of the Company's partners or counterparties to perform their obligations under existing arrangements, including development projects, power purchase and sale arrangements, hedging arrangements or other commercial activities; and
cause other unpredicted events which may have an adverse impact on the Company’s results of operations, financial condition, risk exposure and liquidity.
The situation surrounding COVID-19 remains fluid and the potential for a material impact on the Company’s results of operations, financial condition, risk exposure and liquidity increases the longer the virus impacts the level of economic activity in the United States and globally. NRG cannot reasonably estimate with any degree of certainty the future impact of COVID-19, or any resurgence of COVID-19 or other pandemic may have on the Company’s results of operations, financial position, risk exposure and liquidity.
Risks related to the proposed acquisition of Direct Energy
The Company may be unable to consummate the acquisition of Direct Energy because it may not be able to obtain the approvals necessary to do so, or the combined company may be required to comply with material restrictions or conditions that might impact the parties' interests in consummating the transaction.
On July 24, 2020, the Company entered into a definitive purchase agreement with Centrica to acquire its North American retail business, Direct Energy (the "Purchase Agreement"). Before the acquisition may be completed, Centrica will need to obtain shareholder approval in connection with the proposed transaction. In addition, the completion of the acquisition is conditioned on certain customary closing conditions, including the expiration or termination of the applicable waiting period under the HSR Act, and the receipt of approvals or expiration of applicable waiting periods under the Federal Power Act and the Canadian Competition Act. These governmental authorities may impose conditions on the completion, or require changes to the terms, of the transaction, including conditions on or changes to the business, or operations of the combined company following completion of the acquisition. These conditions or changes could impose additional costs on or limit the revenues or income of the combined company following the acquisition, which could have a material adverse effect on the financial results of the combined company and/or cause either NRG or Centrica to abandon the acquisition. In addition, the regulatory review

92

processes to be pursued in connection with the transaction, and any litigation that may arise from these processes or otherwise, may materially delay the closing of the acquisition.
Furthermore, prior to the approval of the transaction by its shareholders, Centrica is permitted to respond to unsolicited acquisition proposals that constitute or are reasonably likely to lead to a superior proposal, and to engage in negotiations with, and provide information to, parties that submit these proposals. As a result, Centrica can terminate the Purchase Agreement to accept a superior proposal.In addition, theboard of directors of Centrica can change its recommendation for the NRG transaction if the failure to do so would be inconsistent with the fiduciary duties of the Centrica directors, in which case the Purchase Agreement would automatically terminate

If the Company is unable to complete the acquisition, it will still incur and will remain liable for significant transaction costs, including financing, legal, accounting, filing, and other costs relating to the transaction. Also, if the transaction is not completed due to the failure to obtain antitrust or competition approvals for the acquisition, or the Company decides to terminate the transaction in accordance with the purchase agreement due to conditions imposed or sought to be imposed in connection with obtaining these approvals, the Company will be required to pay Centrica a termination fee of $180 million.

If completed, the acquisition of Direct Energy may not achieve its intended results.
The Company entered into the Purchase Agreement with the expectation that the acquisition would result in various benefits, including, among other things, cost savings and operating efficiencies. Achieving the anticipated benefits of the acquisition is subject to a number of uncertainties, including whether the businesses of NRG and Direct Energy are integrated in an efficient and effective manner. Failure to achieve these anticipated benefits could result in increased costs, lower-than-expected revenues or income generated by the combined company and diversion of management's time and energy and could have an adverse effect on the Company's business, financial results and prospects.
The Company will be subject to business uncertainties and contractual restrictions while the acquisition of Direct Energy is pending that could adversely affect its financial results.
Uncertainty about the effects of the acquisition of Direct Energy on employees, customers and suppliers may have an adverse effect on NRG's business. Although the Company intends to take steps designed to reduce any adverse effects, these uncertainties may impair its ability to attract, retain and motivate key personnel until the acquisition is completed and for a period of time thereafter, and could cause customers, suppliers and others that deal with it to seek to change existing business relationships.
Employee retention and recruitment may be particularly challenging prior to the completion of the acquisition, as employees and prospective employees may experience uncertainty about their future roles with the combined company. If, despite the Company's retention and recruiting efforts, key employees depart or fail to accept employment with NRG because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the combined company, the Company's financial results could be affected.
The pursuit of the acquisition and the preparation for the integration of NRG and Direct Energy may place a significant burden on management and internal resources. The diversion of management attention away from ongoing business concerns and any difficulties encountered in the transition and integration process could affect the Company's business, results of operations and financial condition.
In addition, the Company is obligated under the Purchase Agreement to take all actions necessary to obtain antitrust and competition approvals for the acquisition, subject to its right not to take actions that would have a material adverse effect as described in the Purchase Agreement. If the antitrust and competition approvals required for the transaction are not obtained and either NRG or Centrica terminates the Purchase Agreement for this reason, the Company will be required to pay Centrica a termination fee of $180 million. In addition, the Company has agreed not to take any actions that would materially delay the satisfaction of any of the closing conditions to the transaction or prevent any of those conditions from being satisfied. This restriction on the Company's actions may prevent it from pursuing otherwise attractive business opportunities and making other changes to its business prior to completion of the acquisition or termination of the Purchase Agreement.
