Business Combinations [Abstract]
Acquisitions	Acquisitions In June 2019, an indirect subsidiary of NEP completed the acquisition from NEER (June 2019 acquisition) of the following: • 100% of the membership interests in Ashtabula Wind II, LLC, a project company that owns a 120 MW wind generation facility located in North Dakota; • 100% of the membership interests in Garden Wind, LLC, a project company that owns a 150 MW wind generation facility (Story County II) located in Iowa; • 100% of the membership interests in White Oak Energy Holdings, LLC, which owns 100% of the membership interests of White Oak Energy LLC, which owns a 150 MW wind generation facility located in Illinois; • 100% of the Class C membership interests in Rosmar Holdings, LLC (Rosmar), which represent a 49.99% noncontrolling ownership interest in two solar generation facilities, Marshall and Roswell, with a total combined generating capacity of approximately 132 MW located in Minnesota and New Mexico, respectively; and • 49.99% of the membership interests, representing a controlling ownership interest, in Silver State South Solar, LLC (Silver State), which indirectly owns a 250 MW solar generation facility located in Nevada. NEER retained ownership interests in Rosmar and Silver State and remains the managing member of Rosmar. Thus, NEP's interest in Rosmar is reflected within investments in equity method investees on the condensed consolidated balance sheets. NEER's remaining interest in Silver State is reflected within noncontrolling interests on the condensed consolidated balance sheets (see Note 10 - Noncontrolling Interests). The purchase price included approximately $1,020 million in cash consideration, plus working capital of $12 million. Under the acquisition method, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair value. All fair value measurements of assets acquired and liabilities assumed were based on significant estimates and assumptions, including Level 3 (unobservable) inputs, which require judgment. Estimates and assumptions include the projected timing and amount of future cash flows, discount rates reflecting risk inherent in future cash flows and future market prices. The following table summarizes the final amounts recognized by NEP for the estimated fair value of assets acquired and liabilities assumed in the June 2019 acquisition: (millions) Total consideration transferred $ 1,032 Identifiable assets acquired and liabilities assumed Cash $ 4 Accounts receivable, other receivables and prepaid expenses 159 Property, plant and equipment – net 350 Intangible assets – PPAs 1,110 Goodwill 25 Other non-current assets 133 Accounts payable, accrued expenses and other current liabilities (132) Other non-current liabilities (155) Noncontrolling interest (462) Total net identifiable assets, at fair value $ 1,032 In November 2019, Meade Pipeline Investment, LLC (the Meade purchaser), an indirect subsidiary of NEP, acquired all of the ownership interests in Meade Pipeline Co LLC (Meade) which owns an approximately 39.2% aggregate ownership interest in the Central Penn Line (CPL), a 185-mile natural gas pipeline that operates in Pennsylvania and a 40% ownership interest in an expansion project (the expansion) of the gas pipeline. NEP's indirect ownership interest in Meade, including Meade's ownership interests in the CPL and the expansion, is reflected as investments in equity method investees.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue is recognized when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. NEP's operating revenues are generated primarily from various non-affiliated parties under PPAs and natural gas transportation agreements. NEP's operating revenues from contracts with customers are partly offset by the amortization of intangible assets - PPAs. Revenue is recognized as energy and any related renewable energy attributes are delivered, based on rates stipulated in the respective PPAs, or natural gas transportation services are performed. NEP believes that the obligation to deliver energy and provide the natural gas transportation services is satisfied over time as the customer simultaneously receives and consumes benefits provided by NEP. In addition, NEP believes that the obligation to deliver renewable energy attributes is satisfied at multiple points in time, with the control of the renewable energy attribute being transferred at the same time the related energy is delivered. Included in NEP’s operating revenues for the three months ended September 30, 2020 is $184 million and $53 million, for the nine months ended September 30, 2020 is $533 million and $157 million, for the three months ended September 30, 2019 is $213 million and $52 million, and for the nine months ended September 30, 2019 is $513 million and $155 million, of revenue from contracts with customers for renewable energy sales and natural gas transportation services, respectively. NEP's accounts receivable are primarily associated with revenues earned from contracts with customers. Receivables represent unconditional rights to consideration and reflect the differences in timing of revenue recognition and cash collections. For substantially all of NEP's receivables, regardless of the type of revenue transaction from which the receivable originated, customer and counterparty credit risk is managed in the same manner and the terms and conditions of payment are similar. NEP recognizes revenues as energy and any related renewable energy attributes are delivered or natural gas transportation services are performed, consistent with the amounts billed to customers based on rates stipulated in the respective PPAs. NEP considers the amount billed to represent the value of energy delivered or services provided to the customer. NEP’s customers typically receive bills monthly with payment due within 30 days. The contracts with customers related to pipeline service revenues contain a fixed price related to firm natural gas transportation capacity with maturity dates ranging from 2020 to 2035. At September 30, 2020, NEP expects to record approximately $2.0 billion of revenues over the remaining terms of the related contracts as the capacity is provided. Revenues yet to be earned under contracts with customers to deliver energy and any related energy attributes, which have maturity dates ranging from 2026 to 2046, will vary based on the volume of energy delivered. At September 30, 2020, NEP expects to record approximately $205 million of revenues related to the fixed price components of one PPA through 2039 as the energy is delivered.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income taxes are calculated for NEP as a single taxpaying corporation for U.S. federal and state income taxes (based on its election to be taxed as a corporation). NEP recognizes in income its applicable ownership share of U.S. income taxes due to the disregarded tax status of substantially all of the U.S. projects under NEP OpCo. Net income or loss attributable to noncontrolling interests includes minimal U.S. taxes. The effective tax rate for the three and nine months ended September 30, 2020 was approximately 11% and 9%, respectively, and for the three and nine months ended September 30, 2019 was approximately 7% and 7%, respectively, and was primarily affected by tax expense (benefit) attributable to noncontrolling interests of approximately $(28) million and $61 million for the three and nine months ended September 30, 2020, respectively, and $38 million and $80 million for the three and nine months ended September 30, 2019, respectively.

Fair Value Measurements

Fair Value Measurements	9 Months Ended
	Sep. 30, 2020
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value of assets and liabilities are determined using either unadjusted quoted prices in active markets (Level 1) or pricing inputs that are observable (Level 2) whenever that information is available and using unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available. NEP uses several different valuation techniques to measure the fair value of assets and liabilities relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those assets and liabilities that are measured at fair value on a recurring basis. Certain financial instruments may be valued using multiple inputs including discount rates, counterparty credit ratings and credit enhancements. NEP’s assessment of the significance of any particular input to the fair value measurement requires judgment and may affect the placement of those assets and liabilities within the fair value hierarchy levels. Non-performance risk, including the consideration of a credit valuation adjustment, is also considered in the determination of fair value for all assets and liabilities measured at fair value. Transfers between fair value hierarchy levels occur at the beginning of the period in which the transfer occurred. Cash Equivalents and Restricted Cash Equivalents - The fair value of money market funds that are included in cash and cash equivalents, other current assets and other non-current assets on the condensed consolidated balance sheets is estimated using a market approach based on current observable market prices. Interest Rate Contracts - NEP estimates the fair value of its derivatives using an income approach based on a discounted cash flows valuation technique utilizing the net amount of estimated future cash inflows and outflows related to the agreements. The primary inputs used in the fair value measurements include the contractual terms of the derivative agreements, current interest rates and credit profiles. The significant inputs for the resulting fair value measurement are market-observable inputs and the measurements are reported as Level 2 in the fair value hierarchy. NEP’s financial assets and liabilities and other fair value measurements made on a recurring basis by fair value hierarchy level are as follows: September 30, 2020 December 31, 2019 Level 1 Level 2 Total Level 1 Level 2 Total (millions) Assets: Cash equivalents $ 3 $ — $ 3 $ 16 $ — $ 16 Interest rate contracts — 53 53 — 9 9 Total assets $ 3 $ 53 $ 56 $ 16 $ 9 $ 25 Liabilities: Interest rate contracts $ — $ 1,073 $ 1,073 $ — $ 427 $ 427 Total liabilities $ — $ 1,073 $ 1,073 $ — $ 427 $ 427 Financial Instruments Recorded at Other than Fair Value - The carrying amounts and estimated fair values of other financial instruments recorded at other than fair value are as follows: September 30, 2020 December 31, 2019 Carrying Fair Carrying Fair (millions) Long-term debt, including current maturities (a) $ 3,903 $ 4,016 $ 4,144 $ 4,235 ____________________ (a) At September 30, 2020 and December 31, 2019, approximately $3,990 million and $4,211 million, respectively, of the fair value is estimated using a market approach based on quoted market prices for the same or similar issues (Level 2); the balance is estimated using an income approach utilizing a discounted cash flow valuation technique, considering the current credit profile of the debtor (Level 3).

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activity	Derivative Instruments and Hedging Activity NEP uses derivative instruments (primarily interest rate swaps) to manage the interest rate cash flow risk associated with outstanding and expected future debt issuances and borrowings. NEP records all derivative instruments that are required to be marked to market as either assets or liabilities on its condensed consolidated balance sheets and measures them at fair value each reporting period. NEP does not utilize hedge accounting for its derivative instruments. All changes in the derivatives' fair value are recognized in interest expense in the condensed consolidated statements of income (loss). At September 30, 2020 and December 31, 2019, the net notional amounts of the interest rate contracts were approximately $7,082 million and $6,859 million, respectively. During the nine months ended September 30, 2019, NEP reclassified approximately $6 million from AOCI to interest expense primarily because the related future transactions being hedged were no longer going to occur. At September 30, 2020, NEP's AOCI does not include any amounts related to cash flow hedges. Cash flows from the interest rate contracts are reported in cash flows from operating activities in the condensed consolidated statements of cash flows. Fair Value of Derivative Instruments - The tables below present NEP's gross derivative positions, based on the total fair value of each derivative instrument, at September 30, 2020 and December 31, 2019, as required by disclosure rules, as well as the location of the net derivative positions, based on the expected timing of future payments, on the condensed consolidated balance sheets.

At September 30, 2020 and December 31, 2019, the aggregate fair value of NEP's derivative instruments with contingent risk features that were in a liability position was approximately $971 million and $420 million, respectively.

Variable Interest Entities

Variable Interest Entities	9 Months Ended
	Sep. 30, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities NEP has identified NEP OpCo, a limited partnership with a general partner and limited partners, as a VIE. NEP has consolidated the results of NEP OpCo and its subsidiaries because of its controlling interest in the general partner of NEP OpCo. At September 30, 2020, NEP owned an approximately 41.8% limited partner interest in NEP OpCo and NEE Equity owned a noncontrolling 58.2% limited partner interest in NEP OpCo (NEE's noncontrolling interest). The assets and liabilities of NEP OpCo as well as the operations of NEP OpCo represent substantially all of NEP's assets and liabilities and its operations. In addition, at September 30, 2020, NEP OpCo consolidated 12 VIEs related to certain subsidiaries that have sold differential membership interests in entities which own and operate 20 wind electric generation facilities. These entities are considered VIEs because the holders of the differential membership interests do not have substantive rights over the significant activities of these entities. The assets, primarily property, plant and equipment - net, and liabilities, primarily asset retirement obligation and non- current due to related party, of the VIEs, totaled approximately $4,699 million and $127 million, respectively, at September 30, 2020 and $4,814 million and $122 million, respectively, at December 31, 2019. At September 30, 2020, NEP OpCo also consolidated four VIEs related to the sales of noncontrolling Class B interests in certain NEP subsidiaries. See Note 10 - Noncontrolling Interests. These entities are considered VIEs because the holders of the noncontrolling Class B interests do not have substantive rights over the significant activities of the entities. The assets, primarily property, plant and equipment - net and intangible assets - PPAs, and the liabilities, primarily long-term debt, other long-term liabilities and asset retirement obligation, of these VIEs totaled approximately $7,770 million and $1,586 million, respectively, at September 30, 2020 and $7,900 million and $1,448 million, respectively, at December 31, 2019. These VIEs include three other VIEs related to Rosmar, Silver State and Meade. See Note 1. In addition, certain of these VIEs contain entities which have sold differential membership interests and approximately $2,073 million and $2,122 million of assets and $56 million and $53 million of liabilities are also included in the disclosure of the VIEs related to differential membership interests at September 30, 2020 and December 31, 2019, respectively. NEP has an indirect equity method investment in three NEER solar projects with a total generating capacity of 277 MW. Through a series of transactions, a subsidiary of NEP issued 1,000,000 NEP OpCo Class B Units, Series 1 and 1,000,000 NEP OpCo Class B Units, Series 2, to NEER for approximately 50% of the ownership interests in the three solar projects (non-economic ownership interests). NEER, as holder of the NEP OpCo Class B Units, will retain 100% of the economic rights in the projects to which the respective Class B Units relate, including the right to all distributions paid by the project subsidiaries that own the projects to NEP OpCo. NEER has agreed to indemnify NEP against all risks relating to NEP’s ownership of the projects until NEER offers to sell economic interests to NEP and NEP accepts such offer, if NEP chooses to do so. NEER has also agreed to continue to manage the operation of the projects at its own cost, and to contribute to the projects any capital necessary for the operation of the projects, until NEER offers to sell economic interests to NEP and NEP accepts such offer. At September 30, 2020 and December 31, 2019, NEP's equity method investment related to the non-economic ownership interests of approximately $10 million and $11 million, respectively, is reflected as other non-current assets and $21 million and $7 million, respectively, is reflected as other non-current liabilities on the condensed consolidated balance sheets. All equity in earnings of the non-economic ownership interests is allocated to net income attributable to noncontrolling interests. NEP is not the primary beneficiary and therefore does not consolidate these entities because it does not control any of the ongoing activities of these entities, was not involved in the initial design of these entities and does not have a controlling interest in these entities.

(c) At September 30, 2020, approximately $836 million of borrowings were outstanding under the existing credit agreement of the Meade purchaser and Pipeline Investment Holdings, LLC (Meade credit agreement). In February 2020, NEP OpCo and its direct subsidiary (loan parties) entered into an amendment of their existing revolving credit facility. The amendments to the revolving credit facility include, among other things, an extension of the maturity from February 2024 to February 2025. NEP OpCo and its subsidiaries' secured long-term debt agreements are secured by liens on certain assets and contain provisions which, under certain conditions, could restrict the payment of distributions or related party fee payments. At September 30, 2020, NEP and its subsidiaries were in compliance with all financial debt covenants under their financings. Equity - On October 20, 2020, the board of directors of NEP authorized a distribution of $0.5950 per common unit payable on November 13, 2020 to its common unitholders of record on November 5, 2020. During the three and nine months ended September 30, 2020, NEP issued 1.8 million NEP common units upon the conversion of preferred units on a one-for-one basis and issued approximately 5.7 million NEP common units upon the conversion of $300 million of senior unsecured convertible notes (convertible notes). In October 2020, NEP received approximately $30 million in cash related to the unwinding of a capped call transaction that was entered into in connection with the issuance of the convertible notes and NEP issued approximately 1.2 million NEP common units upon the conversion of preferred units on a one-for-one basis. Earnings (Loss) Per Unit - Diluted earnings (loss) per unit is based on the weighted-average number of common units and potential common units outstanding during the period, including the dilutive effect of the convertible notes and preferred units. The dilutive effect of the convertible notes and preferred units is computed using the if-converted method. The reconciliation of NEP's basic and diluted earnings (loss) per unit for the three and nine months ended September 30, 2020 and 2019 is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (millions, except per unit amounts) Numerator: Net income (loss) attributable to NEP – basic $ 56 $ (72) $ (119) $ (122) Adjustments for convertible notes and preferred units (a) 2 — — — Net income (loss) attributable to NEP used to compute diluted earnings (loss) per unit $ 58 $ (72) $ (119) $ (122) Denominator: Weighted-average number of common units outstanding – basic 67.7 59.9 66.2 57.4 Effect of dilutive convertible notes and preferred units (a) 8.2 — — — Weighted-average number of common units outstanding and assumed conversions 75.9 59.9 66.2 57.4 Earnings (loss) per unit attributable to NEP: Basic $ 0.83 $ (1.21) $ (1.80) $ (2.12) Assuming dilution $ 0.76 $ (1.21) $ (1.80) $ (2.12) ———————————— (a) Due to the net losses incurred during the nine months ended September 30, 2020 and the three and nine months ended September 30, 2019, the weighted-average number of common units issuable pursuant to the convertible notes and preferred units totaling approximately 9.6 million, 15.9 million and 18.4 million, respectively, were not included in the calculation of diluted loss per unit due to their antidilutive effect.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Each project entered into O&M agreements and ASAs with subsidiaries of NEER whereby the projects pay a certain annual fee plus actual costs incurred in connection with certain O&M and administrative services performed under these agreements. These services are reflected as operations and maintenance in the condensed consolidated statements of income (loss). Additionally, a NEP subsidiary pays an affiliate for transmission services which are reflected as operations and maintenance in the condensed consolidated statements of income (loss). Certain projects have also entered into various types of agreements including those related to shared facilities and transmission lines, transmission line easements, technical support and construction coordination with subsidiaries of NEER whereby certain fees or cost reimbursements are paid to, or received by, certain subsidiaries of NEER. Management Services Agreement - Under the MSA, an indirect wholly owned subsidiary of NEE provides operational, management and administrative services to NEP, including managing NEP’s day-to-day affairs and providing individuals to act as NEP’s executive officers and directors, in addition to those services that are provided under the existing O&M agreements and ASAs described above between NEER subsidiaries and NEP subsidiaries. NEP OpCo pays NEE an annual management fee equal to the greater of 1% of the sum of NEP OpCo’s net income plus interest expense, income tax expense and depreciation and amortization expense less certain non-cash, non-recurring items for the most recently ended fiscal year and $4 million (as adjusted for inflation beginning in 2016), which is paid in quarterly installments with an additional payment each January to the extent 1% of the sum of NEP OpCo’s net income plus interest expense, income tax expense and depreciation and amortization expense less certain non-cash, non-recurring items for the preceding fiscal year exceeds $4 million (as adjusted for inflation beginning in 2016). NEP OpCo also makes certain payments to NEE based on the achievement by NEP OpCo of certain target quarterly distribution levels to its unitholders. NEP’s O&M expenses for the three and nine months ended September 30, 2020 include approximately $29 million and $82 million, respectively, and for the three and nine months ended September 30, 2019 include $24 million and $68 million, respectively, related to the MSA. Cash Sweep and Credit Support Agreement - NEP OpCo is a party to the CSCS agreement with NEER under which NEER and certain of its affiliates provide credit support in the form of letters of credit and guarantees to satisfy NEP’s subsidiaries’ contractual obligations. NEP OpCo pays NEER an annual credit support fee based on the level and cost of the credit support provided, payable in quarterly installments. NEP’s O&M expenses for the three and nine months ended September 30, 2020 include approximately $1 million and $4 million, respectively, and for the three and nine months ended September 30, 2019 include $1 million and $4 million, respectively, related to the CSCS agreement. NEER and certain of its affiliates may withdraw funds (Project Sweeps) received by NEP OpCo under the CSCS agreement, or its subsidiaries in connection with certain long-term debt agreements, and hold those funds in accounts belonging to NEER or its affiliates to the extent the funds are not required to pay project costs or otherwise required to be maintained by NEP's subsidiaries. NEER and its affiliates may keep the funds until the financing agreements permit distributions to be made, or, in the case of NEP OpCo, until such funds are required to make distributions or to pay expenses or other operating costs or NEP OpCo otherwise demands the return of such funds. If NEER or its affiliates fail to return withdrawn funds when required by NEP's subsidiaries’ financing agreements, the lenders will be entitled to draw on any credit support provided by NEER or its affiliates in the amount of such withdrawn funds. If NEER or one of its affiliates realizes any earnings on the withdrawn funds prior to the return of such funds, it will be permitted to retain those earnings. At September 30, 2020 and December 31, 2019, the cash sweep amounts held in accounts belonging to NEER or its affiliates were approximately $82 million and $12 million, respectively, and are included in due from related parties on the condensed consolidated balance sheets. Guarantees and Letters of Credit Entered into by Related Parties - Certain PPAs include requirements of the project entities to meet certain performance obligations. NEECH or NEER has provided letters of credit or guarantees for certain of these performance obligations and payment of any obligations from the transactions contemplated by the PPAs . In addition, certain financing agreements require cash and cash equivalents to be reserved for various purposes . In accordance with the terms of these financing agreements, guarantees from NEECH have been substituted in place of these cash and cash equivalents reserve requirements. Also, under certain financing agreements, indemnifications have been provided by NEECH. In addition, certain interconnection agreements and site certificates require letters of credit or a surety bond to secure certain payment or restoration obligations related to those agreements. NEECH also guarantees the Project Sweep amounts held in accounts belonging to NEER, as described above. At September 30, 2020, NEECH or NEER guaranteed or provided indemnifications, letters of credit or surety bonds totaling approximately $636 million related to these obligations. Agreements related to the sale of differential membership interests require NEER to guarantee payments due by the VIEs and the indemnifications to the VIEs' respective investors. At September 30, 2020, NEER guaranteed a total of approximately $11 million related to these obligations. Due to Related Party - Non-current amounts due to related party on the condensed consolidated balance sheets primarily represent amounts owed by certain of NEP's wind projects to NEER to refund NEER for certain transmission costs paid on behalf of the wind projects. Amounts will be paid to NEER as the wind projects receive payments from third parties for related notes receivable recorded in other non-current assets on the condensed consolidated balance sheets. Transportation and Fuel Management Agreements - A subsidiary of NEP assigned to a subsidiary of NEER certain gas commodity agreements in exchange for entering into transportation agreements and a fuel management agreement whereby the benefits of the gas commodity agreements (net of transportation paid to the NEP subsidiary) are passed back to the NEP subsidiary. NEP recognized revenues related to the transportation and fuel management agreements of approximately $2 million and $12 million during the three and nine months ended September 30, 2020, respectively, and $2 million and $5 million during the three and nine months ended September 30, 2019, respectively.

Accounting Policies [Abstract]
Summary of Significant Accounting and Reporting Policies	. Summary of Significant Accounting and Reporting Policies Restricted Cash - A t September 30, 2020 and December 31, 2019 , NEP had approximately $3 million and $3 million, respectively, of restricted cash included in other current assets on NEP's condensed consolidated balance sheets. Restricted cash at September 30, 2020 and December 31, 2019 is primarily related to collateral deposits from a counterparty. Restricted cash reported as current assets are recorded as such based on the anticipated use of these funds. Reference Rate Reform - In March 2020, the Financial Accounting Standards Board (FASB) issued an accounting standards update which provides certain options to apply GAAP guidance on contract modifications and hedge accounting as companies transition from the London Inter-Bank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates that are yet to be determined or finalized. NEP’s contracts that reference LIBOR or other interbank offered rates mainly relate to debt and derivative instruments. The standards update was effective upon issuance and can be applied prospectively through December 31, 2022. NEP is currently evaluating whether to apply the options provided by the standards update with regard to its contracts that reference LIBOR or other interbank offered rates as an interest rate benchmark. Noncontrolling Interests - At September 30, 2020, the Class B noncontrolling ownership interests (the Class B noncontrolling ownership interests in NEP Renewables sold in 2018 and NEP Renewables II, NEP Pipelines and STX Midstream sold in 2019), the differential membership interests, NEE's approximately 58.2% noncontrolling limited partner interest in NEP OpCo and NEER's approximately 50% noncontrolling ownership interest in Silver State, as well as a non-affiliated party's 10% interest in one of the Texas pipelines and the non-economic ownership interests are reflected as noncontrolling interests on the condensed consolidated balance sheets. The impact of the net income (loss) attributable to the differential membership interests and the Class B noncontrolling ownership interests are allocated to NEE's noncontrolling ownership interest and the net income attributable to NEP based on the respective ownership percentage of NEP OpCo.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Development, Engineering and Construction Commitments - At September 30, 2020, indirect subsidiaries of NEP had several engineering, procurement and construction contracts and a funding commitment related to the repowering of certain wind facilities and expansion projects at certain pipelines. Those contracts have varying payment terms and some include performance obligations that allow the NEP subsidiaries to receive liquidated damages if the contractor does not perform. As of September 30, 2020, the NEP subsidiaries had purchased approximately $274 million related to these projects, of which $50 million was purchased from NEER. Such costs primarily have been capitalized in property, plant and equipment - net on the condensed consolidated balance sheets. As of September 30, 2020, the NEP subsidiaries have remaining commitments under these contracts of approximately $97 million. PG&E Bankruptcy - The Genesis, Desert Sunlight and Shafter solar projects have PPAs with PG&E. On January 29, 2019, PG&E filed a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. PG&E’s Chapter 11 filing, or related events, caused events of default under the related financings which, among other things, blocked the distribution of cash generated by those projects. On July 1, 2020, PG&E emerged from bankruptcy, curing the related events of default that remained outstanding. On July 23, 2020, NEP received a distribution of approximately $65 million from Desert Sunlight. Coronavirus Pandemic - NEP is closely monitoring the global outbreak of the novel coronavirus (COVID-19) and is taking steps intended to mitigate the potential risks to NEP posed by COVID-19. NEP has implemented its pandemic plan, which includes various processes and procedures intended to limit the impact of COVID-19 on its business. These processes and procedures include the pandemic plan implemented by NEER related to services NEER provides to NEP. To date, there has been no material impact on NEP's operations, financial performance, or liquidity as a result of COVID-19; however, the ultimate severity or duration of the outbreak or its effects on the global, national or local economy, the capital and credit markets, the services NEER provides to NEP, or NEP's customers and suppliers is uncertain. NEP cannot predict whether COVID-19 will have a material impact on its business, financial condition, liquidity, results of operations and ability to make cash distributions to its unitholders.
