FORWARD-LOOKING STATEMENTS

This report includes forward-looking statements within the meaning of the federal securities laws. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions, strategies, future events or performance (often, but not always, through the use of words or phrases such as result, are expected to, will continue, is anticipated, believe, will, could, should, would, estimated, may, plan, potential, future, projection, goals, target, outlook, predict and intend or words of similar meaning) are not statements of historical facts and may be forward looking. Forward-looking statements involve estimates, assumptions and uncertainties. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors (in addition to any assumptions and other factors referred to specifically in connection with such forward-looking statements) that could have a significant impact on NEP's operations and financial results, and could cause NEP's actual results to differ materially from those contained or implied in forward-looking statements made by or on behalf of NEP in this Form 10-Q, in presentations, on its website, in response to questions or otherwise.

Operational Risks

• NEP has a limited operating history and its projects include renewable energy projects that have a limited operating history. Such projects may not perform as expected.

• NEP's ability to make cash distributions to its unitholders is affected by wind and solar conditions at its renewable energy projects.

• NEP's business, financial condition, results of operations and prospects can be materially adversely affected by weather conditions, including, but not limited to, the impact of severe weather.

• Operation and maintenance of renewable energy projects involve significant risks that could result in unplanned power outages, reduced output, personal injury or loss of life.

• Natural gas gathering and transmission activities involve numerous risks that may result in accidents or otherwise affect the Texas pipelines’ operations.

• NEP depends on certain of the renewable energy projects and pipelines in its portfolio for a substantial portion of its anticipated cash flows.

• NEP is pursuing the expansion of natural gas pipelines in its portfolio that will require up-front capital expenditures and expose NEP to project development risks.

• NEP's ability to maximize the productivity of the Texas pipeline business and to complete potential pipeline expansion projects is dependent on the continued availability of natural gas production in the Texas pipelines’ areas of operation.

• Terrorist or similar attacks could impact NEP's projects, pipelines or surrounding areas and adversely affect its business.

• The ability of NEP to obtain insurance and the terms of any available insurance coverage could be materially adversely affected by international, national, state or local events and company-specific events, as well as the financial condition of insurers. NEP's insurance coverage does not insure against all potential risks and it may become subject to higher insurance premiums.

• Warranties provided by the suppliers of equipment for NEP's projects may be limited by the ability of a supplier to satisfy its warranty obligations, or by the terms of the warranty, so the warranties may be insufficient to compensate NEP for its losses.

• Supplier concentration at certain of NEP's projects may expose it to significant credit or performance risks.

• NEP relies on interconnection, transmission and other pipeline facilities of third parties to deliver energy from its renewable energy projects and to transport natural gas to and from the Texas pipelines. If these facilities become unavailable, NEP's projects and pipelines may not be able to operate, deliver energy or become partially or fully unavailable to transport natural gas.

• NEP's business is subject to liabilities and operating restrictions arising from environmental, health and safety laws and regulations, compliance with which may require significant capital expenditures, increase NEP's cost of operations and affect or limit its business plans.

• NEP's renewable energy projects may be adversely affected by legislative changes or a failure to comply with applicable energy regulations.

• A change in the jurisdictional characterization of some of the Texas pipeline entities' assets, or a change in law or regulatory policy, could result in increased regulation of these assets, which could have a material adverse effect on NEP's business, financial condition, results of operations and ability to make cash distributions to its unitholders.

• NEP may incur significant costs and liabilities as a result of pipeline integrity management program testing and any necessary pipeline repair or preventative or remedial measures.

• The Texas pipelines’ operations could incur significant costs if the Pipeline and Hazardous Materials Safety Administration or the Railroad Commission of Texas adopts more stringent regulations.

• Pemex may claim certain immunities under the Foreign Sovereign Immunities Act and Mexican law, and the Texas pipeline entities' ability to sue or recover from Pemex for breach of contract may be limited and may be exacerbated if there is a deterioration in the economic relationship between the U.S. and Mexico.

• NEP does not own all of the land on which the projects in its portfolio are located and its use and enjoyment of the property may be adversely affected to the extent that there are any lienholders or leaseholders that have rights that are superior to NEP's rights or the BLM suspends its federal rights-of-way grants.

• NEP is subject to risks associated with litigation or administrative proceedings that could materially impact its operations, including, but not limited to, proceedings related to projects it acquires in the future.

4

• NEP's cross-border operations require NEP to comply with anti-corruption laws and regulations of the U.S. government and non-U.S. jurisdictions.

• NEP is subject to risks associated with its ownership or acquisition of projects or pipelines that remain under construction, which could result in its inability to complete construction projects on time or at all, and make projects too expensive to complete or cause the return on an investment to be less than expected.

Contract Risks

• NEP relies on a limited number of customers and is exposed to the risk that they are unwilling or unable to fulfill their contractual obligations to NEP or that they otherwise terminate their agreements with NEP.

• NEP may not be able to extend, renew or replace expiring or terminated PPAs and natural gas transportation agreements at favorable rates or on a long-term basis.

• If the energy production by or availability of NEP's U.S. renewable energy projects is less than expected, they may not be able to satisfy minimum production or availability obligations under the U.S. Project Entities’ PPAs.

Risks Related to NEP's Acquisition Strategy and Future Growth

• NEP's growth strategy depends on locating and acquiring interests in additional projects consistent with its business strategy at favorable prices.

• NEP OpCo's partnership agreement requires that it distribute its available cash, which could limit NEP's ability to grow and make acquisitions.

• Lower prices for other fuel sources may reduce the demand for wind and solar energy.

• Reductions in demand for natural gas in the United States or Mexico and low market prices of natural gas could materially adversely affect the Texas pipelines’ operations and cash flows.

• Government laws, regulations and policies providing incentives and subsidies for clean energy could be changed, reduced or eliminated at any time and such changes may negatively impact NEP's growth strategy.

• NEP's growth strategy depends on the acquisition of projects developed by NEE and third parties, which face risks related to project siting, financing, construction, permitting, the environment, governmental approvals and the negotiation of project development agreements.

• Acquisitions of existing clean energy projects involve numerous risks.

• Renewable energy procurement is subject to U.S. state regulations, with relatively irregular, infrequent and often competitive procurement windows.

• NEP may continue to acquire other sources of clean energy and may expand to include other types of assets. Any further acquisition of non-renewable energy projects may present unforeseen challenges and result in a competitive disadvantage relative to NEP's more-established competitors.

• NEP faces substantial competition primarily from regulated utilities, developers, IPPs, pension funds and private equity funds for opportunities in North America.

• The natural gas pipeline industry is highly competitive, and increased competitive pressure could adversely affect NEP's business.

Risks Related to NEP's Financial Activities

• NEP may not be able to access sources of capital on commercially reasonable terms, which would have a material adverse effect on its ability to consummate future acquisitions.

• Restrictions in NEP's and its subsidiaries' financing agreements could adversely affect NEP's business, financial condition, results of operations and ability to make cash distributions to its unitholders.

• NEP's cash distributions to its unitholders may be reduced as a result of restrictions on NEP's subsidiaries’ cash distributions to NEP under the terms of their indebtedness.

• NEP's subsidiaries’ substantial amount of indebtedness may adversely affect NEP's ability to operate its business, and its failure to comply with the terms of its subsidiaries' indebtedness could have a material adverse effect on NEP's financial condition.

• Currency exchange rate fluctuations may affect NEP's operations.

• NEP is exposed to risks inherent in its use of interest rate swaps.

Risks Related to NEP's Relationship with NEE

• Under the CSCS agreement, NEP receives credit support from NEE and its affiliates. NEP's subsidiaries may default under contracts or become subject to cash sweeps if credit support is terminated, if NEE or its affiliates fail to honor their obligations under credit support arrangements, or if NEE or another credit support provider ceases to satisfy creditworthiness requirements, and NEP will be required in certain circumstances to reimburse NEE for draws that are made on credit support.

• NEER or one of its affiliates is permitted to borrow funds received by NEP's subsidiaries and is obligated to return these funds only as needed to cover project costs and distributions or as demanded by NEP OpCo.

• NEP's financial condition and ability to make distributions to its unitholders, as well as its ability to grow distributions in the future, is highly dependent on NEER’s performance of its obligations to return all or a portion of these funds.

• NEP may not be able to consummate future acquisitions.

• NEER's right of first refusal may adversely affect NEP's ability to consummate future sales or to obtain favorable sale terms.

• NEP GP and its affiliates may have conflicts of interest with NEP and have limited duties to NEP and its unitholders.

5

• NEP GP and its affiliates and the directors and officers of NEP are not restricted in their ability to compete with NEP, whose business is subject to certain restrictions.

• NEP may only terminate the MSA under certain specified conditions.

• If the agreements with NEE Management or NEER are terminated, NEP may be unable to contract with a substitute service provider on similar terms.

• NEP's arrangements with NEE limit NEE's potential liability, and NEP has agreed to indemnify NEE against claims that it may face in connection with such arrangements, which may lead NEE to assume greater risks when making decisions relating to NEP than it otherwise would if acting solely for its own account.

Risks Related to Ownership of NEP's Units

• NEP's ability to make distributions to its unitholders depends on the ability of NEP OpCo to make cash distributions to its limited partners.

• If NEP incurs material tax liabilities, NEP's distributions to its unitholders may be reduced, without any corresponding reduction in the amount of the IDR fee.

• Holders of NEP's units may be subject to voting restrictions.

• NEP's partnership agreement replaces the fiduciary duties that NEP GP and NEP's directors and officers might have to holders of its common units with contractual standards governing their duties.

• NEP's partnership agreement restricts the remedies available to holders of NEP's common units for actions taken by NEP's directors or NEP GP that might otherwise constitute breaches of fiduciary duties.

• Certain actions of NEP require the consent of NEP GP.

• Holders of NEP's common units and preferred units currently cannot remove NEP GP without NEE's consent.

• NEE's interest in NEP GP and the control of NEP GP may be transferred to a third party without unitholder consent.

• The IDR fee may be assigned to a third party without unitholder consent.

• NEP may issue additional units without unitholder approval, which would dilute common unitholder interests.

• Reimbursements and fees owed to NEP GP and its affiliates for services provided to NEP or on NEP's behalf will reduce cash distributions to or from NEP OpCo and from NEP to NEP's unitholders, and the amount and timing of such reimbursements and fees will be determined by NEP GP and there are no limits on the amount that NEP OpCo may be required to pay.

• Discretion in establishing cash reserves by NEP OpCo GP may reduce the amount of cash distributions to unitholders.

• NEP OpCo can borrow money to pay distributions, which would reduce the amount of credit available to operate NEP's business.

• Increases in interest rates could adversely impact the price of NEP's common units, NEP's ability to issue equity or incur debt for acquisitions or other purposes and NEP's ability to make cash distributions to its unitholders.

• The price of NEP's common units may fluctuate significantly and unitholders could lose all or part of their investment.

• The liability of holders of NEP's common units, which represent limited partnership interests in NEP, may not be limited if a court finds that unitholder action constitutes control of NEP's business.

• Unitholders may have liability to repay distributions that were wrongfully distributed to them.

• Provisions in NEP's partnership agreement may discourage or delay an acquisition of NEP that NEP unitholders may consider favorable, which could decrease the value of NEP's common units, and could make it more difficult for NEP unitholders to change the board.

• The board, a majority of which may be affiliated with NEE, decides whether to retain separate counsel, accountants or others to perform services for NEP.

• The New York Stock Exchange does not require a publicly traded limited partnership like NEP to comply with certain of its corporate governance requirements.

• Any issuance of preferred units will dilute common unitholders’ ownership in NEP and may decrease the amount of cash available for distribution for each common unit.

• The preferred units have rights, preferences and privileges that are not held by, and are preferential to the rights of, holders of the common units.

Taxation Risks

• NEP's future tax liability may be greater than expected if NEP does not generate NOLs sufficient to offset taxable income or if tax authorities challenge certain of NEP's tax positions.

• NEP's ability to use NOLs to offset future income may be limited.

• NEP will not have complete control over NEP's tax decisions.

• A valuation allowance may be required for NEP's deferred tax assets.

• Distributions to unitholders may be taxable as dividends.

These factors should be read together with the risk factors included in Part I, Item 1A. Risk Factors in the 2017 Form 10-K and investors should refer to that section of the 2017 Form 10-K. Any forward-looking statement speaks only as of the date on which such statement is made, and NEP undertakes no obligation to update any forward-looking statement to reflect events or circumstances, including, but not limited to, unanticipated events, after the date on which such statement is made, unless otherwise required by law. New factors emerge from time to time and it is not possible for management to predict all of such factors, nor can it assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained or implied in any forward-looking statement.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

The accompanying condensed consolidated financial statements should be read in conjunction with the 2017 Form 10-K. In the opinion of NEP management, all adjustments (consisting of normal recurring accruals) considered necessary for fair financial statement presentation have been made. Certain amounts included in the prior year's condensed consolidated financial statements have been reclassified to conform to the current year's presentation. The results of operations for an interim period generally will not give a true indication of results for the year.

1. Acquisitions

During 2017, a subsidiary of NEP completed acquisitions from NEER which were transfers of assets between entities under common control that were required to be accounted for as if the transfers occurred since the inception of common control, with prior periods retrospectively adjusted to furnish comparative information. Accordingly, the accompanying condensed consolidated financial statements have been retrospectively adjusted for the three and nine months ended September 30, 2017 to include the historical results and financial position of the common control acquisitions prior to their respective acquisition dates.

In August 2017, NEP and NEP GP implemented governance changes that, among other things, enhanced NEP unitholder governance rights. The new governance structure established a NEP board of directors whereby NEP unitholders have the ability to nominate and elect board members, subject to certain limitations and requirements. As a result of these governance changes, beginning in January 2018, acquisitions from NEER are no longer treated as common control acquisitions and NEP's financial statements will no longer be retrospectively adjusted for such acquisitions.

In August 2018, an indirect subsidiary of NEP entered into an agreement with indirect subsidiaries of NEER to acquire NEP Renewables, LLC (NEP Renewables) which owns 100% of the membership interests in each of:

• Breckinridge Wind Class A Holdings, LLC, which indirectly owns an approximately 98 MW wind generation facility located in Oklahoma;

• Carousel Wind Holdings, LLC, which indirectly owns an approximately 150 MW wind generation facility located in Colorado;

• Monarch Wind Holdings, LLC, which indirectly owns two wind generation facilities, Javelina II and Rush Springs Wind, with a combined generating capacity of approximately 450 MW, located in Texas and Oklahoma, respectively;

• Mountain View Solar Holdings, LLC, which indirectly owns a 20 MW solar generation facility located in Nevada;

• Pacific Plains Wind Class A Holdings, LLC, which indirectly owns three wind generation facilities, Bluff Point, Cottonwood and Golden Hills North, with a combined generating capacity of approximately 255 MW, located in Indiana, Nebraska and California, respectively; and

• Palomino Wind Holdings, LLC, which indirectly owns three wind generation facilities located in Kansas, Kingman I, Kingman II and Ninnescah, with a combined generating capacity of approximately 415 MW.

NEP expects to complete the acquisition before December 31, 2018, subject to customary closing conditions and the receipt of certain regulatory approvals, for a total consideration of approximately $1,275 million, subject to customary working capital and other adjustments, plus the assumption of approximately $930 million in existing noncontrolling interests related to differential membership investors and $38 million of existing debt.

2. Revenue

Effective January 1, 2018, NEP adopted an accounting standards update that provides guidance on the recognition of revenue from contracts with customers and requires additional disclosures regarding such contracts (new revenue standard). Under the new revenue standard, 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 adopted the new revenue standard using the modified retrospective approach applying it only to contracts that were not complete at January 1, 2018. NEP did not recognize a cumulative effect adjustment on January 1, 2018 because revenue recognized under the new accounting standard remained consistent with historical practice.

NEP's operating revenues are generated primarily from various non-affiliated parties under long-term power purchase agreements, FIT agreements and RESOP agreements (collectively, PPAs) and natural gas transportation agreements. 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. Substantially all of the PPAs are accounted for as operating leases and are not considered contracts with customers within the scope of the new revenue standard. Included in NEP’s operating revenues for the three months ended September 30, 2018 is approximately $11 million and $52 million and for the nine months ended September 30, 2018 is $40 million and $162 million of revenue from contracts with customers for

13

NEXTERA ENERGY PARTNERS, LP

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(unaudited)

renewable energy sales and natural gas transportation services, respectively. NEP's accounts receivable are primarily associated with revenues earned from contracts with customers as well as lease transactions. 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 2018 to 2035. At September 30, 2018, NEP expects to record approximately $1.9 billion of revenues over the remaining terms of the related contacts 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 2030 to 2035, will vary based on the volume of energy delivered.

3. Income Taxes

For periods through December 31, 2017, when NEP acquired a NEER project, income taxes were calculated on the predecessor method using the separate return method applied to the group of renewable energy projects acquired. As a result of the governance changes discussed in Note 1, beginning in January 2018, acquisitions from NEER are no longer treated as common control acquisitions, and income taxes are calculated on the successor method where 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). Because NEP OpCo is a limited partnership, NEP only recognizes in income its applicable ownership share of U.S. income taxes related to the U.S. projects and, prior to the sale of Canadian Holdings, the Canadian projects. NEP's former Canadian subsidiaries were all Canadian taxpayers, and therefore NEP recognized in income all of the Canadian taxes. Income taxes include NEP's applicable ownership share of U.S. taxes and 100% of Canadian taxes. Net income or loss attributable to noncontrolling interests includes no U.S. taxes and NEER's applicable ownership share of Canadian taxes. Net income attributable to NEP includes NEP's applicable ownership share of U.S. and Canadian taxes.

On December 22, 2017, the Tax Cuts and Jobs Act (tax reform) was signed into law which, among other things, reduced the federal corporate income tax rate from 35% to 21% effective January 1, 2018. As a result, NEP performed an analysis to preliminarily revalue its deferred income taxes and included an estimate of changes in the balances in NEP's December 31, 2017 financial statements. At December 31, 2017, the revaluation reduced NEP’s net deferred income tax assets by approximately $101 million, which decreased NEP’s 2017 net income and net income attributable to NEP. While NEP continues to believe that the provisional tax reform adjustment is a reasonable estimate of the effects on its existing deferred taxes, additional analysis and detailed reviews are still being performed to finalize the accounting for the remeasurement of deferred tax assets and liabilities as a result of the enactment of tax reform. NEP expects any final adjustments to the provisional amounts to be recorded in the fourth quarter of 2018 upon filing of all 2017 income tax returns.

The effective tax rates for the three months ended September 30, 2018 and 2017 were approximately 12% and 30%, respectively, and for the nine months ended September 30, 2018 and 2017 were approximately 3% and 24%, respectively. The effective tax rate is affected by recurring items, such as the relative amount of income earned in jurisdictions (earnings mix), valuation allowances on deferred tax assets, taxes attributable to the noncontrolling interests and the taxation of Canadian income in both Canada and the U.S. During the nine months ended September 30, 2018, the disposal of Canadian Holdings (see Note 10 - Disposal of Canadian Holdings) resulted in an overall tax benefit of approximately $47 million. The benefit resulted from the removal of the historical Canadian deferred tax liabilities of approximately $69 million offset by US tax expense of $22 million related to the gain. During the nine months ended September 30, 2018, NEP recorded an income tax charge of approximately $20 million related to the $231 million adjustment to differential membership interests as a result of the change in federal corporate income taxes due to tax reform that became effective January 1, 2018 (see Note 10 - Accounting for Partial Sales of Nonfinancial Assets).

4. 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

14

NEXTERA ENERGY PARTNERS, LP

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(unaudited)

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, restricted cash 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 and Foreign Currency 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, foreign currency exchange 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, 2018						December 31, 2017
	Level 1		Level 2		Total		Level 1		Level 2		Total
	(millions)
Assets:
Cash equivalents	$	45	$	—	$	45	$	61	$	—	$	61
Restricted cash equivalents(a)	24		—		24		31		—		31
Interest rate contracts	—		81		81		—		15		15
Total assets	$	69	$	81	$	150	$	92	$	15	$	107

____________________

(a) At September 30, 2018 and December 31, 2017, approximately $9 million and $7 million, respectively, of restricted cash equivalents are included in other non-current assets on NEP's condensed consolidated balance sheets.

Financial Instruments Recorded at Other than Fair Value - The carrying amount of short-term debt approximates its fair value. The carrying amounts and estimated fair values of other financial instruments recorded at other than fair value are as follows:

	September 30, 2018				December 31, 2017
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(millions)
Long-term debt, including current maturities(a)	$	3,555	$	3,512	$	4,317	$	4,456

____________________

(a) At September 30, 2018 and December 31, 2017, approximately $3,036 million and $3,552 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).

5. Derivative Instruments and Hedging Activity

NEP uses derivative instruments (primarily interest rate swaps) to manage the interest rate cash flow risk associated primarily 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 in 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. In general, the commencement and termination dates of the interest rate swap agreements and the related hedging relationship coincide with the corresponding dates of the underlying variable-rate debt instruments. At September 30, 2018 and December 31, 2017, the combined notional amounts of the interest rate contracts were approximately $8,222 million and $3,609 million, respectively.

At September 30, 2018, NEP's AOCI included amounts related to discontinued cash flow hedges, which have expiration dates through 2030. At September 30, 2018, less than $1 million of net unrealized losses are expected to be reclassified into interest expense within the next 12 months as interest payments are made. Such amount assumes no change in scheduled principal

(unaudited)

payments. Cash flows from these interest rate swap contracts are reported in cash flows from operating activities in the condensed consolidated statements of cash flows.

Prior to the sale of Canadian Holdings discussed in Note 10 - Disposal of Canadian Holdings, NEP entered into certain foreign currency exchange contracts to economically hedge its cash flows from foreign currency rate fluctuations. At December 31, 2017, the notional amount of the foreign currency contracts was approximately $62 million. During the three months ended September 30, 2018 and 2017, NEP recorded less than $1 million of losses and $2 million of losses, respectively, and $13 million of gains and $5 million of losses during the nine months ended September 30, 2018 and 2017, respectively, related to the foreign currency contracts in other - net in the condensed consolidated statements of income. In April 2018, NEP entered into a foreign exchange forward agreement with a notional amount of CAD $741 million to manage foreign currency exchange rate risk associated with the cash consideration NEP received upon closing of the sale of Canadian Holdings. In July 2018, the CAD $741 million hedge agreement was settled.

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, 2018 and December 31, 2017, 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.

Credit-Risk-Related Contingent Features - Certain of NEP's derivative instruments contain credit-related cross-default and material adverse change triggers, none of which contain requirements to maintain certain credit ratings or financial ratios. At September 30, 2018 and December 31, 2017, the aggregate fair value of NEP's derivative instruments with contingent risk features that were in a liability position was approximately $57 million and $17 million, respectively.

6. Variable Interest Entities

NEP has identified NEP OpCo as a VIE. NEP OpCo is a limited partnership with a general partner and limited partners. 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, 2018, NEP owned an approximately 35.6% limited partner interest in NEP OpCo and NEE Equity owned a noncontrolling 64.4% 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, 2018, NEP OpCo consolidated seven VIEs related to certain subsidiaries that have sold differential membership interests in entities which own and operate ten 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 $2,775 million and $75 million, respectively, at September 30, 2018. The assets, primarily property, plant and equipment - net, and liabilities, primarily deferral related to differential membership interests, totaled approximately $2,840 million and $1,515 million, respectively, at December 31, 2017.

In April 2015, a subsidiary of NEP made an equity method investment in three NEER solar projects. 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 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. 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, 2018 and December 31, 2017, NEP's equity method investment related to the non-economic ownership interests is reflected as investments in non-economic ownership interests 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.

7. Capitalization

Equity - During the nine months ended September 30, 2018, NEP issued approximately 1.7 million common units under its $150 million at-the-market equity issuance program (ATM program) implemented in July 2018, which replaced its prior program, for gross proceeds of approximately $82 million. Fees related to the ATM program totaled approximately $1 million in 2018.

On October 22, 2018, the board of directors of NEP authorized a distribution of $0.45 per common unit payable on November 14, 2018 to its common unitholders of record on November 6, 2018.

In August 2018, NEP, NEP Renewables Holdings, LLC (NEP Renewables Holdings) and NEP Renewables entered into a membership interest purchase agreement (membership purchase agreement) with a third-party investor (Class B purchaser) for the purpose of financing the acquisition of NEP Renewables. The Class B purchaser has committed to pay approximately $750 million to NEP Renewables Holdings for 100% of the noncontrolling Class B interest in NEP Renewables, representing an approximately 59% investment in NEP Renewables, subject to certain conditions. NEP Renewables Holdings will retain 100% of the Class A interest, representing an approximately 41% investment in NEP Renewables. NEP will consolidate NEP Renewables which will be considered a VIE because the Class B purchaser does not have substantive rights over the significant activities of NEP Renewables.

Under the amended and restated limited liability company agreement for NEP Renewables (the LLC agreement) that will be entered into at funding, NEP will receive 85% of NEP Renewables’ cash distributions for the first three years after funding, and the Class B purchaser will receive 15%. After three years, NEP will receive 20% of NEP Renewables’ cash distributions and the Class B purchaser will receive 80%. From the third to the fourth anniversary after funding, NEP has the option (the buyout right), subject to certain limitations and extensions, to purchase 100% of the Class B purchaser’s interest in NEP Renewables at a buyout price that implies a 7.75% pre-tax return to the Class B purchaser (inclusive of all prior distributions). If exercised, NEP has the right to pay at least 70% of the buyout price in NEP non-voting common units, issued at the then-current market price of NEP common units, with the balance paid in cash, subject to certain limitations. Beginning January 1, 2025, NEP will give the Class B purchaser, under a

17

NEXTERA ENERGY PARTNERS, LP

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(unaudited)

registration rights agreement to be entered into at funding, certain rights to require NEP, under certain circumstances, to initiate underwritten offerings for the common units that are issuable if NEP exercises the buyout right.

NEP's limited partnership agreement will be amended and restated to establish the rights of the NEP non-voting common units. The NEP non-voting common units will have, among other terms, the right to receive pro rata quarterly cash distributions and rights, subject to certain limitations, to convert the NEP non-voting common units into NEP common units on a one-for-one basis.

Earnings Per Unit - Diluted earnings per unit are 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 per unit is as follows:

	(millions, except per unit amounts)

9. 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. Additionally, a NEP subsidiary pays an affiliate for transmission services which are reflected as operations and maintenance in the condensed consolidated statements of income. 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, 2018 include approximately $20 million and $57 million, respectively, and for the three and nine months ended September 30, 2017 include approximately $17 million and $49 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 subsidiaries may provide credit support in the form of letters of credit and guarantees to satisfy NEP’s subsidiaries’ contractual obligations. NEP OpCo will pay 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, 2018 include approximately $1 million and $3 million, respectively, and for the three and nine months ended September 30, 2017 include approximately $1 million and $3 million, respectively, related to the CSCS agreement.

NEER and certain of its subsidiaries 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 subsidiaries 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 subsidiaries 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 fails 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 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, 2018 and December 31, 2017, the cash sweep amounts held in accounts belonging to

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(unaudited)

NEER or its subsidiaries were approximately $807 million and $87 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 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, 2018, NEECH or NEER guaranteed or provided indemnifications, letters of credit or bonds totaling approximately $575 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, 2018, NEER guaranteed a total of approximately $59 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 - In connection with the Texas pipelines acquisition, 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. During the three and nine months ended September 30, 2018, NEP recognized less than $1 million and approximately $2 million, respectively, and for the three and nine months ended September 30, 2017 NEP recognized $2 million and $7 million, respectively, in revenues related to the transportation and fuel management agreements.

10. Summary of Significant Accounting and Reporting Policies

Restricted Cash - In the fourth quarter of 2017, NEP early adopted an accounting standards update which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. NEP adopted the standards update retrospectively, which adoption did not have a material impact to the condensed consolidated statements of cash flows.

Current restricted cash on NEP's condensed consolidated balance sheets and approximately $19 million and $19 million of other non-current assets on NEP's condensed consolidated balance sheets at September 30, 2018 and December 31, 2017, respectively, are held by certain subsidiaries to pay for certain capital or operating expenditures, as well as to fund required equity contributions pursuant to restrictions contained in the subsidiaries' debt agreements. Restricted cash reported as current assets are recorded as such based on the anticipated use of these funds.

Disposal of Canadian Holdings - In June 2018, a subsidiary of NEP completed the sale of Canadian Holdings for cash proceeds of approximately CAD $740 million (USD $563 million at June 29, 2018), subject to post-closing working capital adjustments. In addition, the purchaser assumed approximately $676 million of existing debt. Canadian Holdings owned four wind generation facilities and two solar generation facilities located in Ontario, Canada with a generating capacity totaling approximately 396 MW. NEP recognized a gain of approximately $158 million ($205 million after-tax). Income before income taxes associated with Canadian Holdings, excluding the financial statement impacts resulting from the sale in 2018, was approximately $8 million for the three months ended September 30, 2017 and $47 million and $47 million for the nine months ended September 30, 2018 and 2017, respectively.

Accounting for Partial Sales of Nonfinancial Assets - Effective January 1, 2018, NEP adopted an accounting standards update regarding the accounting for partial sales of nonfinancial assets using the modified retrospective approach. This standards update affects the accounting and related financial statement presentation for the sales of differential membership interests to third-party investors. The primary impact of adopting the standards update was an increase to noncontrolling interests which includes the reclassification of the $1,442 million liability reflected as deferral related to differential membership interests on NEP's condensed consolidated balance sheets at December 31, 2017. See the condensed consolidated statements of changes in equity. During the three and nine months ended September 30, 2018, approximately $28 million and $105 million, respectively, was recorded as net loss attributable to noncontrolling interests in NEP's condensed consolidated statements of income as the third-party investors received their portion of the economic attributes of the related facilities. Prior to the adoption, the income related to differential membership interests was being recognized in benefits associated with differential membership interests - net in NEP's condensed consolidated statements of income. Additionally, net loss attributable to noncontrolling interests for the nine months ended September 30, 2018 includes approximately $231 million (after-tax $211 million) related to the reduction of differential membership interests as a result of the change in federal corporate income tax rates effective January 1, 2018.

Noncontrolling Interests - At September 30, 2018 and December 31, 2017, NEP's limited partner interest in NEP OpCo was approximately 35.6% and 34.9%, respectively. At September 30, 2018, NEE's 64.4% noncontrolling interest in NEP OpCo, a non-affiliated party's 10% interest in one of the Texas pipelines and the interests related to differential membership interests discussed above are reflected as noncontrolling interests on the condensed consolidated balance sheets. Details of the activity in noncontrolling interests for the nine months ended September 30, 2018 is below:

____________________

(a) Represents the benefits associated with differential membership interests recognized as the third-party investors received their portion of the economic attributes of the related facilities. Approximately $219 million of the loss attributable to differential membership interests benefits NEE's noncontrolling interest and $117 million is reflected as net income attributable to NEP.

Leases - In February 2016, the Financial Accounting Standards Board (FASB) issued an accounting standards update which requires, among other things, that lessees recognize a lease liability, initially measured at the present value of the future lease payments, and a right-of-use asset for all leases (with the exception of short-term leases) (new lease standard). The new lease standard also requires new qualitative and quantitative disclosures for both lessees and lessors. The new lease standard will be effective for NEP beginning January 1, 2019. Early adoption is permitted. The new lease standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as an adjustment to retained earnings as of the date of initial application.

NEP is currently reviewing its portfolio of contracts and evaluating the proper application of the new lease standard to these contracts in order to determine the impact the adoption will have on its consolidated financial statements. NEP is implementing a number of system enhancements to facilitate the identification, tracking and reporting of leases based upon the requirements of the new lease standard. NEP is continuing to assess the transition options and practical expedients and monitoring industry implementation issues.

11. Commitments and Contingencies

Contracts - At September 30, 2018, NEP and its subsidiaries have entered into contracts with expiration dates ranging from 2018 through 2065 for the sale of differential membership interests related to certain wind generation facilities, engineering, procurement and construction contracts and agreements that provide for the right to use the land upon which certain projects are located.

At September 30, 2018, payments under these contracts were estimated as follows:

One of NEP’s solar project's land use agreements includes a right-of-way lease/grant that provides for payments to the BLM for the right to use the public lands upon which the project is located. The lease may be renewed at expiration at the solar project's option and will be subject to the regulations existing at the time of renewal. In connection with the terms of the lease, the solar project obtained a surety bond from a non-affiliated party in favor of the BLM for approximately $23 million. The surety bond remains in effect until the BLM is satisfied that there is no outstanding liability on the bond or satisfactory replacement bond coverage is furnished.

Letter of Credit Facilities - Two of NEP’s projects entered into letter of credit (LOC) facilities under which the LOC lenders may issue standby letters of credit not to exceed approximately $82 million in the aggregate. These LOC facilities have maturity dates of June 2022 and July 2022. At September 30, 2018, approximately $68 million of LOCs was outstanding primarily related to debt service reserves and as security for certain of the projects' agreements, including a PPA.

Acquisition Holdback - At December 31, 2016, the condensed consolidated balance sheets included an acquisition holdback related to the satisfaction of any indemnification obligations of the Texas pipelines sellers through April 2017 (indemnity holdback). During the nine months ended September 30, 2017 the indemnity holdback was released under the terms of the Texas pipelines acquisition agreement and approximately $200 million was paid to the sellers.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

NEP is a growth-oriented limited partnership formed to acquire, manage and own contracted clean energy projects with stable long-term cash flows. At September 30, 2018, NEP owned a controlling, non-economic general partner interest and an approximately 35.6% limited partner interest in NEP OpCo. Through NEP OpCo, NEP owns a portfolio of contracted renewable generation assets consisting of wind and solar projects and a portfolio of contracted natural gas pipeline assets.

This discussion should be read in conjunction with the Notes contained herein and Management's Discussion and Analysis of Financial Condition and Results of Operations appearing in the 2017 Form 10-K. The results of operations for an interim period generally will not give a true indication of results for the year. In the following discussions, all comparisons are with the corresponding items in the prior year period.

During 2017, a subsidiary of NEP completed acquisitions from NEER, which were transfers of assets between entities under common control that were required to be accounted for as if the transfers occurred since the inception of common control, with prior periods retrospectively adjusted to furnish comparative information. Accordingly, the accompanying condensed consolidated financial statements have been retrospectively adjusted for the three and nine months ended September 30, 2017 to include the historical results and financial position of the common control acquisitions prior to their respective acquisition dates. Beginning in January 2018, acquisitions from NEER are no longer treated as common control acquisitions and NEP's financial statements will no longer be retrospectively adjusted for such acquisitions. See Note 1.

In June 2018, a subsidiary of NEP completed the sale of Canadian Holdings which owns four wind generation facilities and two solar generation facilities located in Ontario, Canada with a generating capacity totaling approximately 396 MW. See Note 10 - Disposal of Canadian Holdings.

In August 2018, an indirect subsidiary of NEP entered into an agreement with indirect subsidiaries of NEER to acquire NEP Renewables which indirectly owns interests in ten wind generation facilities and one solar generation facility with generating capacity totaling approximately 1,388 MW. See Note 1.

Three Months Ended September 30, 2018 Compared to Three Months Ended September 30, 2017

Operating Revenues

Operating revenues primarily consist of income from the sale of energy under PPAs and services provided under natural gas transportation agreements. Renewable energy sales decreased approximately $17 million during the three months ended September 30, 2018. Of this amount, approximately $21 million is the result of the sale of Canadian Holdings at the end of the second quarter of 2018. This decrease was partially offset by net favorable wind and solar resource across the portfolio. Texas pipelines service revenues increased approximately $4 million over the same period primarily due to the recognition of revenue related to new contracts.

Operating Expenses

Operations and Maintenance

O&M expense includes interconnection costs, labor expenses, turbine servicing costs, royalty payments, insurance, materials, supplies, shared services and administrative expenses attributable to NEP's projects, and costs and expenses under the MSA, ASAs and O&M agreements. See Note 9. O&M expense also includes the cost of maintaining and replacing certain parts for the projects in the portfolio to maintain, over the long-term, operating income or operating capacity. O&M expense increased approximately $4 million during the three months ended September 30, 2018 primarily due to increases of $3 million in IDR fees related to growth in NEP's distributions to its common unitholders and $4 million primarily related to various project O&M expenses, partially offset by a decrease of approximately $3 million as a result of the sale of Canadian Holdings at the end of the second quarter of 2018.

Depreciation and Amortization

Depreciation and amortization expense reflects costs associated with depreciation and amortization of NEP's assets, based on depreciable asset lives and consistent depreciation methodologies. Depreciation and amortization expense also includes a provision for wind and solar facility dismantlement, asset removal costs and accretion related to asset retirement obligations and the amortization of finite-lived intangible assets.

Depreciation and amortization expense decreased approximately $7 million during the three months ended September 30, 2018 primarily as a result of the sale of Canadian Holdings at the end of the second quarter of 2018.

Other Income (Deductions)

Interest Expense

Interest expense primarily consists of interest on debt and mark-to-market gains and losses on interest rate contracts. Interest expense decreased approximately $81 million during the three months ended September 30, 2018 primarily due to favorable mark-to-market activity of $78 million and a decrease in interest costs of $3 million as a result of the sale of Canadian Holdings at the end of the second quarter of 2018.

Benefits Associated with Differential Membership Interests - net

For the three months ended September 30, 2017, benefits associated with differential membership interests - net reflect benefits recognized by NEP as third-party investors received their portion of the economic attributes, including income tax attributes, of the underlying wind projects net of associated costs. For the three months ended September 30, 2018, NEP recognized approximately $28 million as a loss attributable to noncontrolling interests on the condensed consolidated statements of income. Approximately $18 million of the loss attributable to differential membership interests benefits NEE's noncontrolling interest and $10 million is reflected as net income attributable to NEP.

Income Taxes

Income taxes include NEP's applicable ownership share of U.S. taxes and 100% of Canadian taxes. Net income or loss attributable to noncontrolling interest includes no U.S. taxes and NEER's applicable ownership share of Canadian taxes. Net income attributable to NEP includes NEP's applicable ownership share of U.S. and Canadian taxes.

For the three months ended September 30, 2018, NEP recorded income tax expense of approximately $15 million on income before income taxes of $125 million, resulting in an effective tax rate of 12%. The tax expense is comprised primarily of income tax expense of approximately $26 million at the statutory rate of 21%, partially offset by income tax benefit of $16 million of income tax attributable to noncontrolling interests.

For the three months ended September 30, 2017, NEP recorded income tax expense of approximately $21 million on income before income taxes of $71 million, resulting in an effective tax rate of 30%. The tax expense is comprised primarily of income tax expense of approximately $25 million at the statutory rate of 35%, partially offset by income tax benefit of $7 million of income tax attributable to noncontrolling interests.

25

Due to the transition from predecessor, prior to January 1, 2018, to successor method of accounting for income taxes, comparing current period results to the same period in the prior year does not provide meaningful information. See Note 3.

Net Income Attributable to Noncontrolling Interests

For the three months ended September 30, 2018 and 2017, net income attributable to noncontrolling interests reflects the net income attributable to NEE's noncontrolling interest in NEP OpCo and a non-affiliated party's 10% interest in one of the Texas pipelines. Additionally, for the three months ended September 30, 2018, net income attributable to noncontrolling interests reflects the loss allocated to differential membership interests investors. See Note 10 - Noncontrolling Interests. Net income attributable to noncontrolling interests increased $22 million during the three months ended September 30, 2018 primarily due to the allocation of NEP's net income based on the ownership share of the respective noncontrolling interests as well as the allocation of the differential membership interest loss.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017

Operating Revenues

Renewable energy sales decreased approximately $17 million during the nine months ended September 30, 2018. Of this amount, approximately $22 million is a result of the sale of Canadian Holdings at the end of the second quarter of 2018. This was partially offset by net favorable wind resource across the portfolio. Texas pipelines service revenues increased approximately $22 million over the same period primarily due to the recognition of revenue related to new contracts.

Operating Expenses

Operations and Maintenance

O&M expense increased approximately $9 million during the nine months ended September 30, 2018 primarily due to an increase of $8 million in IDR fees related to growth in NEP's distributions to its common unitholders and $5 million primarily related to various project O&M expenses, partially offset by $4 million as a result of the sale of Canadian Holdings at the end of the second quarter of 2018.

Depreciation and Amortization

Depreciation and amortization expense decreased approximately $17 million during the nine months ended September 30, 2018 as a result of the sale of Canadian Holdings at the end of the second quarter of 2018 and Canadian Holdings being held for sale during a portion of 2018 prior to the sale.

Gain on Disposal of Canadian Holdings

During the nine months ended September 30, 2018, a subsidiary of NEP completed the sale of Canadian Holdings and NEP recognized a pre-tax gain of approximately $158 million. See Note 10 - Disposal of Canadian Holdings.

Other Income (Deductions)

Interest Expense

Interest expense decreased approximately $61 million during the nine months ended September 30, 2018 primarily due to favorable mark-to-market activity of $69 million, partially offset by $10 million in higher interest cost and fees related to additional debt issuances during 2017, net of the repayment of certain term loans during 2017.

Benefits Associated with Differential Membership Interests - net

For the nine months ended September 30, 2017, benefits associated with differential membership interests - net reflect benefits recognized by NEP as third-party investors received their portion of the economic attributes, including income tax attributes, of the underlying wind projects net of associated costs. For the nine months ended September 30, 2018, NEP recognized approximately $336 million as a loss attributable to noncontrolling interests on the condensed consolidated statements of income, of which approximately $231 million related to the change in federal corporate income tax rates that became effective January 1, 2018. See Note 10 - Accounting for Partial Sales of Nonfinancial Assets. Approximately $219 million of the loss attributable to differential membership interests benefits NEE's noncontrolling interest and $117 million is reflected as net income attributable to NEP.

Equity in Earnings of Non-Economic Ownership Interests

Equity in earnings of non-economic ownership interests increased by approximately $13 million during the nine months ended September 30, 2018 primarily due to mark-to-market gains on certain interest rate derivative contracts recorded at the related projects.

Other - net

The increase in other - net for the nine months ended September 30, 2018 primarily reflects an approximately $15 million increase in gains related to foreign currency exchange contracts. See Note 5.

Income Taxes

For the nine months ended September 30, 2018, NEP recorded income tax expense of approximately $13 million on income before income taxes of $398 million, resulting in an effective tax rate of 3%. The tax expense is comprised primarily of income tax expense of approximately $84 million at the statutory rate of 21%, $20 million related to the adjustment to differential membership interests as a result of the change in federal corporate income tax rates due to tax reform (see Note 10 - Accounting for Partial Sales of Nonfinancial Assets) and $4 million of state income taxes, partially offset by income tax benefits of $69 million related to the removal of the historical Canadian deferred tax liabilities (see Note 3) and $33 million of income tax attributable to noncontrolling interests.

For the nine months ended September 30, 2017, NEP recorded income tax expense of approximately $52 million on income before income taxes of $219 million, resulting in an effective tax rate of 24%. The tax expense is comprised primarily of income tax expense of approximately $77 million at the statutory rate of 35%, partially offset by income tax benefits of $5 million related to foreign tax differential and $21 million of income tax attributable to noncontrolling interests.

Due to the transition from predecessor, prior to January 1, 2018, to successor method of accounting for income taxes, comparing current period results to the same period in the prior year does not provide meaningful information. See Note 3.

Net Income Attributable to Noncontrolling Interests

For the nine months ended September 30, 2018 and 2017, net income attributable to noncontrolling interests reflects the net income attributable to NEE's noncontrolling interest in NEP OpCo and a non-affiliated party's 10% interest in one of the Texas pipelines. Additionally, for the nine months ended September 30, 2018, net income attributable to noncontrolling interests reflects the loss allocated to differential membership interests investors. See Note 10 - Noncontrolling Interests. Net income attributable to noncontrolling interests increased $37 million during the nine months ended September 30, 2018 primarily due to the allocation of NEP's net income, including the gain on disposal of Canadian Holdings discussed above, based on the ownership share of the respective noncontrolling interests, partially offset by the allocation of the differential membership interest adjustment discussed above.

Liquidity and Capital Resources

NEP’s ongoing operations use cash to fund O&M expenses, maintenance capital expenditures, debt service payments and distributions to common and preferred unitholders. NEP expects to satisfy these requirements primarily with internally generated cash flow. In addition, as a growth-oriented limited partnership, NEP expects from time to time to make acquisitions and other investments. These acquisitions and investments are expected to be funded with borrowings under credit facilities or term loans, issuances of indebtedness, issuances of additional NEP common units or preferred units, other financing structures, cash on hand and cash generated from operations.

These sources of funds are expected to be adequate to provide for NEP's short-term and long-term liquidity and capital needs, although its ability to make future acquisitions, expand existing projects and increase its distributions to common unitholders will depend on its ability to access the capital markets on acceptable terms.

As a normal part of its business, depending on market conditions, NEP expects from time to time to consider opportunities to repay, redeem, repurchase or refinance its indebtedness. In addition, NEP expects from time to time to consider potential investments in new acquisitions. These events may cause NEP to seek additional debt or equity financing, which may not be available on acceptable terms or at all. Additional debt financing, if available, could impose operating restrictions, additional cash payment obligations and additional covenants.

NEP OpCo has agreed to allow NEER or one of its affiliates to withdraw funds received by NEP OpCo or its subsidiaries and to hold those funds in accounts of NEER or one of its affiliates to the extent the funds are not required to pay project costs or otherwise required to be maintained by NEP's subsidiaries, 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. NEP OpCo will have a claim for any funds that NEER fails to return:

• when required by its subsidiaries’ financings;

• when its subsidiaries’ financings otherwise permit distributions to be made to NEP OpCo;

• when funds are required to be returned to NEP OpCo; or

• when otherwise demanded by NEP OpCo.

In addition, NEER and certain of its subsidiaries may withdraw funds in connection with certain long-term debt agreements and hold those funds in accounts belonging to NEER or its subsidiaries and provide credit support in the amount of such withdrawn funds. If NEER fails 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 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.

Liquidity Position

At September 30, 2018 and December 31, 2017, NEP's liquidity position was approximately $1,647 million and $1,005 million, respectively. The table below provides the components of NEP’s liquidity position:

	September 30, 2018			December 31, 2017
	(millions)
Cash and cash equivalents	$	76		$	154
Amounts due under the CSCS agreement	807			87

____________________

(a) Excludes current restricted cash of approximately $15 million and $25 million at September 30, 2018 and December 31, 2017, respectively. See Note 2 - Restricted Cash.

Management believes that NEP's liquidity position and cash flows from operations will be adequate to finance O&M, capital expenditures, distributions to its unitholders and liquidity commitments. Management continues to regularly monitor NEP's financing needs consistent with prudent balance sheet management.

Equity

During the nine months ended September 30, 2018, NEP issued approximately 1.7 million common units under its ATM program. Approximately $68 million of common units remain available to be issued under NEP's ATM program at September 30, 2018.

In August 2018, NEP entered into a membership purchase agreement to sell 100% of the noncontrolling Class B interest in NEP Renewables for approximately $750 million. See Note 7 - Equity.

In July 2018, NEP filed a shelf registration statement with the SEC, which became effective upon filing, for an unspecified amount of securities, which shelf registration statement replaced a prior shelf registration statement that has expired. The amount of securities issuable by NEP is established from time to time by its board of directors. Securities that may be issued under the registration statement include common units, preferred units, warrants, rights, debt securities, equity purchase contracts and equity purchase units.

Contractual Obligations

NEP's contractual obligations as of September 30, 2018 were as follows:

Cash Distributions to Unitholders

During the nine months ended September 30, 2018, NEP distributed approximately $69 million to its common unitholders. On October 22, 2018, the board of directors of NEP authorized a distribution of $0.45 per common unit payable on November 14, 2018 to its common unitholders of record on November 6, 2018. During the nine months ended September 30, 2018, NEP distributed approximately $15 million to its preferred unitholders and accrued $6 million in preferred distributions to be paid in November 2018.

Cash Flows

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017

The following table reflects the changes in cash flows for the comparative periods:

	2018			2017(a)			Change
	(millions)
Nine Months Ended September 30,
Net cash provided by operating activities	$	269		$	293		$	(24	)
Net cash used in investing activities	$	(213	)	$	(808	)	$	595
Net cash provided by (used in) financing activities	$	(142	)	$	502		$	(644	)

_________________________

(a) Prior-period financial information has been retrospectively adjusted as discussed in Note 1 and Note 10 - Restricted Cash.

Net Cash Provided by Operating Activities

The decrease in net cash provided by operating activities was primarily driven by approximately $17 million for the timing of accounts payable and accrued expenses primarily related to the sale of Canadian Holdings and $18 million related to the timing of interest payments. This was partially offset by the absence of the $14 million portion of the acquisition holdback payment in 2017 reflected as cash flows from operating activities.

Net Cash Used in Investing Activities

	2018			2017
	(millions)
Nine Months Ended September 30,
Acquisition of membership interests in subsidiaries	$	—		$	(242	)
Capital expenditures	(10		)	(342		)
Proceeds from the sale of Canadian Holdings - net	517			—
Payments to related parties under CSCS agreement - net	(720		)	(301		)
Proceeds from CITCs	—			77
Net cash used in investing activities	$	(213	)	$	(808	)

The decrease in net cash used in investing activities was primarily driven by the proceeds from the sale of Canadian Holdings, the absence of capital expenditures related to construction activities as a result of the completion of two wind projects at the end of 2016 prior to the NEP acquisition date and the absence of the acquisition of membership interests in subsidiaries in May 2017. This was partially offset by higher cash sweeps under the CSCS agreement.

Net Cash Provided by (Used in) Financing Activities

	2018			2017
	(millions)
Nine Months Ended September 30,
Proceeds from issuance of common units - net	$	81		$	—
Issuances (retirements) of long-term debt - net	(74		)	709
Partners/Members' contributions	32			307
Partners/Members' distributions	(205		)	(232		)
Change in amounts due to related parties	(1		)	(78		)
Proceeds related to differential membership interests - net	40			15
Payment of acquisition holdback	—			(186		)
Other	(15		)	(33		)
Net cash provided by (used in) financing activities	$	(142	)	$	502

The increase in net cash used in financing activities primarily reflects the absence of pre-acquisition member contributions and the absence of the issuances of debt in 2018. This was partially offset by the absence of the payment of the acquisition holdback, the issuance of common units in 2018 and lower member distributions.

New Accounting Rules and Interpretations

Leases - In February 2016, the FASB issued an accounting standards update which requires, among other things, that lessees recognize a lease liability and a right-of-use asset for all leases. See Note 10 - Leases.

Quantitative and Qualitative Disclosures about Market Risk

NEP is exposed to several market risks in its normal business activities. Market risk is the potential loss that may result from market changes associated with its business. The types of market risks include interest rate, counterparty credit and foreign currency risks.

Interest Rate Risk

NEP is exposed to risk resulting from changes in interest rates associated with outstanding and expected future debt issuances and borrowings. NEP manages interest rate exposure by monitoring current interest rates, entering into interest rate swap contracts and using a combination of fixed rate and variable rate debt. Interest rate swaps are used to mitigate and adjust interest rate exposure when deemed appropriate based upon market conditions or when required by financing agreements (see Note 5).

NEP has long-term debt instruments that subject it to the risk of loss associated with movements in market interest rates. At September 30, 2018, approximately 6% of the long-term debt, including current maturities, was exposed to fluctuations in interest expense while the remaining balance was either fixed rate debt or financially hedged. At September 30, 2018, the estimated fair value of NEP's long-term debt was approximately $3.5 billion and the carrying value of the long-term debt was $3.6 billion. Based upon a hypothetical 10% decrease in interest rates, which is a reasonable near-term market change, the fair value of NEP's long-term debt would increase by approximately $98 million.

Counterparty Credit Risk

Risks surrounding counterparty performance and credit risk could ultimately impact the amount and timing of expected cash flows. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties under the terms of their contractual obligations. NEP monitors and manages credit risk through credit policies that include a credit approval process and the use of credit mitigation measures such as prepayment arrangements in certain circumstances. NEP also seeks to mitigate counterparty risk by having a diversified portfolio of counterparties.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

See Management's Discussion - Quantitative and Qualitative Disclosures About Market Risk.

Item 4.  Controls and Procedures

(a)    Evaluation of Disclosure Controls and Procedures

As of September 30, 2018, NEP had performed an evaluation, under the supervision and with the participation of its management, including the chief executive officer and the chief financial officer of NEP, of the effectiveness of the design and operation of NEP's disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)). Based upon that evaluation, the chief executive officer and the chief financial officer of NEP concluded that NEP's disclosure controls and procedures were effective as of September 30, 2018.

(b)    Changes in Internal Control Over Financial Reporting

NEP is continuously seeking to improve the efficiency and effectiveness of its operations and of its internal controls. This results in refinements to processes throughout NEP. However, there has been no change in NEP's internal control over financial reporting (as defined in the Securities Exchange Act of 1934 Rules 13a-15(f) and 15d-15(f)) that occurred during NEP's most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, NEP's internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1A. Risk Factors

There have been no material changes from the risk factors disclosed in the 2017 Form 10-K. The factors discussed in Part I, Item 1A. Risk Factors in the 2017 Form 10-K, as well as other information set forth in this report, which could materially adversely affect NEP's business, financial condition, results of operations, cash available for distribution and prospects should be carefully considered. The risks in the 2017 Form 10-K are not the only risks facing NEP. Additional risks and uncertainties not currently known to NEP, or that are currently deemed to be immaterial, also may materially adversely affect NEP's business, financial condition, results of operations, cash available for distribution and prospects.

Acquisitions

Acquisitions

During 2017, a subsidiary of NEP completed acquisitions from NEER which were transfers of assets between entities under common control that were required to be accounted for as if the transfers occurred since the inception of common control, with prior periods retrospectively adjusted to furnish comparative information. Accordingly, the accompanying condensed consolidated financial statements have been retrospectively adjusted for the three and nine months ended September 30, 2017 to include the historical results and financial position of the common control acquisitions prior to their respective acquisition dates.

In August 2017, NEP and NEP GP implemented governance changes that, among other things, enhanced NEP unitholder governance rights. The new governance structure established a NEP board of directors whereby NEP unitholders have the ability to nominate and elect board members, subject to certain limitations and requirements. As a result of these governance changes, beginning in January 2018, acquisitions from NEER are no longer treated as common control acquisitions and NEP's financial statements will no longer be retrospectively adjusted for such acquisitions.

In August 2018, an indirect subsidiary of NEP entered into an agreement with indirect subsidiaries of NEER to acquire NEP Renewables, LLC (NEP Renewables) which owns 100% of the membership interests in each of:

• Breckinridge Wind Class A Holdings, LLC, which indirectly owns an approximately 98 MW wind generation facility located in Oklahoma;

• Carousel Wind Holdings, LLC, which indirectly owns an approximately 150 MW wind generation facility located in Colorado;

• Monarch Wind Holdings, LLC, which indirectly owns two wind generation facilities, Javelina II and Rush Springs Wind, with a combined generating capacity of approximately 450 MW, located in Texas and Oklahoma, respectively;

• Mountain View Solar Holdings, LLC, which indirectly owns a 20 MW solar generation facility located in Nevada;

• Pacific Plains Wind Class A Holdings, LLC, which indirectly owns three wind generation facilities, Bluff Point, Cottonwood and Golden Hills North, with a combined generating capacity of approximately 255 MW, located in Indiana, Nebraska and California, respectively; and

• Palomino Wind Holdings, LLC, which indirectly owns three wind generation facilities located in Kansas, Kingman I, Kingman II and Ninnescah, with a combined generating capacity of approximately 415 MW.

NEP expects to complete the acquisition before December 31, 2018, subject to customary closing conditions and the receipt of certain regulatory approvals, for a total consideration of approximately $1,275 million, subject to customary working capital and other adjustments, plus the assumption of approximately $930 million in existing noncontrolling interests related to differential membership investors and $38 million of existing debt.

Revenue

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

Effective January 1, 2018, NEP adopted an accounting standards update that provides guidance on the recognition of revenue from contracts with customers and requires additional disclosures regarding such contracts (new revenue standard). Under the new revenue standard, 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 adopted the new revenue standard using the modified retrospective approach applying it only to contracts that were not complete at January 1, 2018. NEP did not recognize a cumulative effect adjustment on January 1, 2018 because revenue recognized under the new accounting standard remained consistent with historical practice.

NEP's operating revenues are generated primarily from various non-affiliated parties under long-term power purchase agreements, FIT agreements and RESOP agreements (collectively, PPAs) and natural gas transportation agreements. 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. Substantially all of the PPAs are accounted for as operating leases and are not considered contracts with customers within the scope of the new revenue standard. Included in NEP’s operating revenues for the three months ended September 30, 2018 is approximately $11 million and $52 million and for the nine months ended September 30, 2018 is $40 million and $162 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 as well as lease transactions. 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 2018 to 2035. At September 30, 2018, NEP expects to record approximately $1.9 billion of revenues over the remaining terms of the related contacts 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 2030 to 2035, will vary based on the volume of energy delivered.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

For periods through December 31, 2017, when NEP acquired a NEER project, income taxes were calculated on the predecessor method using the separate return method applied to the group of renewable energy projects acquired. As a result of the governance changes discussed in Note 1, beginning in January 2018, acquisitions from NEER are no longer treated as common control acquisitions, and income taxes are calculated on the successor method where 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). Because NEP OpCo is a limited partnership, NEP only recognizes in income its applicable ownership share of U.S. income taxes related to the U.S. projects and, prior to the sale of Canadian Holdings, the Canadian projects. NEP's former Canadian subsidiaries were all Canadian taxpayers, and therefore NEP recognized in income all of the Canadian taxes. Income taxes include NEP's applicable ownership share of U.S. taxes and 100% of Canadian taxes. Net income or loss attributable to noncontrolling interests includes no U.S. taxes and NEER's applicable ownership share of Canadian taxes. Net income attributable to NEP includes NEP's applicable ownership share of U.S. and Canadian taxes.

On December 22, 2017, the Tax Cuts and Jobs Act (tax reform) was signed into law which, among other things, reduced the federal corporate income tax rate from 35% to 21% effective January 1, 2018. As a result, NEP performed an analysis to preliminarily revalue its deferred income taxes and included an estimate of changes in the balances in NEP's December 31, 2017 financial statements. At December 31, 2017, the revaluation reduced NEP’s net deferred income tax assets by approximately $101 million, which decreased NEP’s 2017 net income and net income attributable to NEP. While NEP continues to believe that the provisional tax reform adjustment is a reasonable estimate of the effects on its existing deferred taxes, additional analysis and detailed reviews are still being performed to finalize the accounting for the remeasurement of deferred tax assets and liabilities as a result of the enactment of tax reform. NEP expects any final adjustments to the provisional amounts to be recorded in the fourth quarter of 2018 upon filing of all 2017 income tax returns.

The effective tax rates for the three months ended September 30, 2018 and 2017 were approximately 12% and 30%, respectively, and for the nine months ended September 30, 2018 and 2017 were approximately 3% and 24%, respectively. The effective tax rate is affected by recurring items, such as the relative amount of income earned in jurisdictions (earnings mix), valuation allowances on deferred tax assets, taxes attributable to the noncontrolling interests and the taxation of Canadian income in both Canada and the U.S. During the nine months ended September 30, 2018, the disposal of Canadian Holdings (see Note 10 - Disposal of Canadian Holdings) resulted in an overall tax benefit of approximately $47 million. The benefit resulted from the removal of the historical Canadian deferred tax liabilities of approximately $69 million offset by US tax expense of $22 million related to the gain. During the nine months ended September 30, 2018, NEP recorded an income tax charge of approximately $20 million related to the $231 million adjustment to differential membership interests as a result of the change in federal corporate income taxes due to tax reform that became effective January 1, 2018 (see Note 10 - Accounting for Partial Sales of Nonfinancial Assets).

Fair Value Measurements

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, restricted cash 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 and Foreign Currency 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, foreign currency exchange 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:

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 primarily 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 in 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. In general, the commencement and termination dates of the interest rate swap agreements and the related hedging relationship coincide with the corresponding dates of the underlying variable-rate debt instruments. At September 30, 2018 and December 31, 2017, the combined notional amounts of the interest rate contracts were approximately $8,222 million and $3,609 million, respectively.

At September 30, 2018, NEP's AOCI included amounts related to discontinued cash flow hedges, which have expiration dates through 2030. At September 30, 2018, less than $1 million of net unrealized losses are expected to be reclassified into interest expense within the next 12 months as interest payments are made. Such amount assumes no change in scheduled principal payments. Cash flows from these interest rate swap contracts are reported in cash flows from operating activities in the condensed consolidated statements of cash flows.

Prior to the sale of Canadian Holdings discussed in Note 10 - Disposal of Canadian Holdings, NEP entered into certain foreign currency exchange contracts to economically hedge its cash flows from foreign currency rate fluctuations. At December 31, 2017, the notional amount of the foreign currency contracts was approximately $62 million. During the three months ended September 30, 2018 and 2017, NEP recorded less than $1 million of losses and $2 million of losses, respectively, and $13 million of gains and $5 million of losses during the nine months ended September 30, 2018 and 2017, respectively, related to the foreign currency contracts in other - net in the condensed consolidated statements of income. In April 2018, NEP entered into a foreign exchange forward agreement with a notional amount of CAD $741 million to manage foreign currency exchange rate risk associated with the cash consideration NEP received upon closing of the sale of Canadian Holdings. In July 2018, the CAD $741 million hedge agreement was settled.

Credit-Risk-Related Contingent Features - Certain of NEP's derivative instruments contain credit-related cross-default and material adverse change triggers, none of which contain requirements to maintain certain credit ratings or financial ratios. At September 30, 2018 and December 31, 2017, the aggregate fair value of NEP's derivative instruments with contingent risk features that were in a liability position was approximately $57 million and $17 million, respectively.

Variable Interest Entities

Variable Interest Entities

NEP has identified NEP OpCo as a VIE. NEP OpCo is a limited partnership with a general partner and limited partners. 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, 2018, NEP owned an approximately 35.6% limited partner interest in NEP OpCo and NEE Equity owned a noncontrolling 64.4% 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, 2018, NEP OpCo consolidated seven VIEs related to certain subsidiaries that have sold differential membership interests in entities which own and operate ten 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 $2,775 million and $75 million, respectively, at September 30, 2018. The assets, primarily property, plant and equipment - net, and liabilities, primarily deferral related to differential membership interests, totaled approximately $2,840 million and $1,515 million, respectively, at December 31, 2017.

In April 2015, a subsidiary of NEP made an equity method investment in three NEER solar projects. 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 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. 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, 2018 and December 31, 2017, NEP's equity method investment related to the non-economic ownership interests is reflected as investments in non-economic ownership interests 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.

Capitalization

Equity - During the nine months ended September 30, 2018, NEP issued approximately 1.7 million common units under its $150 million at-the-market equity issuance program (ATM program) implemented in July 2018, which replaced its prior program, for gross proceeds of approximately $82 million. Fees related to the ATM program totaled approximately $1 million in 2018.

On October 22, 2018, the board of directors of NEP authorized a distribution of $0.45 per common unit payable on November 14, 2018 to its common unitholders of record on November 6, 2018.

In August 2018, NEP, NEP Renewables Holdings, LLC (NEP Renewables Holdings) and NEP Renewables entered into a membership interest purchase agreement (membership purchase agreement) with a third-party investor (Class B purchaser) for the purpose of financing the acquisition of NEP Renewables. The Class B purchaser has committed to pay approximately $750 million to NEP Renewables Holdings for 100% of the noncontrolling Class B interest in NEP Renewables, representing an approximately 59% investment in NEP Renewables, subject to certain conditions. NEP Renewables Holdings will retain 100% of the Class A interest, representing an approximately 41% investment in NEP Renewables. NEP will consolidate NEP Renewables which will be considered a VIE because the Class B purchaser does not have substantive rights over the significant activities of NEP Renewables.

Under the amended and restated limited liability company agreement for NEP Renewables (the LLC agreement) that will be entered into at funding, NEP will receive 85% of NEP Renewables’ cash distributions for the first three years after funding, and the Class B purchaser will receive 15%. After three years, NEP will receive 20% of NEP Renewables’ cash distributions and the Class B purchaser will receive 80%. From the third to the fourth anniversary after funding, NEP has the option (the buyout right), subject to certain limitations and extensions, to purchase 100% of the Class B purchaser’s interest in NEP Renewables at a buyout price that implies a 7.75% pre-tax return to the Class B purchaser (inclusive of all prior distributions). If exercised, NEP has the right to pay at least 70% of the buyout price in NEP non-voting common units, issued at the then-current market price of NEP common units, with the balance paid in cash, subject to certain limitations. Beginning January 1, 2025, NEP will give the Class B purchaser, under a registration rights agreement to be entered into at funding, certain rights to require NEP, under certain circumstances, to initiate underwritten offerings for the common units that are issuable if NEP exercises the buyout right.

NEP's limited partnership agreement will be amended and restated to establish the rights of the NEP non-voting common units. The NEP non-voting common units will have, among other terms, the right to receive pro rata quarterly cash distributions and rights, subject to certain limitations, to convert the NEP non-voting common units into NEP common units on a one-for-one basis.

Earnings Per Unit - Diluted earnings per unit are 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 per unit is as follows:

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. Additionally, a NEP subsidiary pays an affiliate for transmission services which are reflected as operations and maintenance in the condensed consolidated statements of income. 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, 2018 include approximately $20 million and $57 million, respectively, and for the three and nine months ended September 30, 2017 include approximately $17 million and $49 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 subsidiaries may provide credit support in the form of letters of credit and guarantees to satisfy NEP’s subsidiaries’ contractual obligations. NEP OpCo will pay 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, 2018 include approximately $1 million and $3 million, respectively, and for the three and nine months ended September 30, 2017 include approximately $1 million and $3 million, respectively, related to the CSCS agreement.

NEER and certain of its subsidiaries 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 subsidiaries 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 subsidiaries 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 fails 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 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, 2018 and December 31, 2017, the cash sweep amounts held in accounts belonging to NEER or its subsidiaries were approximately $807 million and $87 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 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, 2018, NEECH or NEER guaranteed or provided indemnifications, letters of credit or bonds totaling approximately $575 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, 2018, NEER guaranteed a total of approximately $59 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 - In connection with the Texas pipelines acquisition, 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. During the three and nine months ended September 30, 2018, NEP recognized less than $1 million and approximately $2 million, respectively, and for the three and nine months ended September 30, 2017 NEP recognized $2 million and $7 million, respectively, in revenues related to the transportation and fuel management agreements.

Accounting Policies [Abstract]

Summary of Significant Accounting and Reporting Policies

Summary of Significant Accounting and Reporting Policies

Restricted Cash - In the fourth quarter of 2017, NEP early adopted an accounting standards update which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. NEP adopted the standards update retrospectively, which adoption did not have a material impact to the condensed consolidated statements of cash flows.

Current restricted cash on NEP's condensed consolidated balance sheets and approximately $19 million and $19 million of other non-current assets on NEP's condensed consolidated balance sheets at September 30, 2018 and December 31, 2017, respectively, are held by certain subsidiaries to pay for certain capital or operating expenditures, as well as to fund required equity contributions pursuant to restrictions contained in the subsidiaries' debt agreements. Restricted cash reported as current assets are recorded as such based on the anticipated use of these funds.

Disposal of Canadian Holdings - In June 2018, a subsidiary of NEP completed the sale of Canadian Holdings for cash proceeds of approximately CAD $740 million (USD $563 million at June 29, 2018), subject to post-closing working capital adjustments. In addition, the purchaser assumed approximately $676 million of existing debt. Canadian Holdings owned four wind generation facilities and two solar generation facilities located in Ontario, Canada with a generating capacity totaling approximately 396 MW. NEP recognized a gain of approximately $158 million ($205 million after-tax). Income before income taxes associated with Canadian Holdings, excluding the financial statement impacts resulting from the sale in 2018, was approximately $8 million for the three months ended September 30, 2017 and $47 million and $47 million for the nine months ended September 30, 2018 and 2017, respectively.

Accounting for Partial Sales of Nonfinancial Assets - Effective January 1, 2018, NEP adopted an accounting standards update regarding the accounting for partial sales of nonfinancial assets using the modified retrospective approach. This standards update affects the accounting and related financial statement presentation for the sales of differential membership interests to third-party investors. The primary impact of adopting the standards update was an increase to noncontrolling interests which includes the reclassification of the $1,442 million liability reflected as deferral related to differential membership interests on NEP's condensed consolidated balance sheets at December 31, 2017. See the condensed consolidated statements of changes in equity. During the three and nine months ended September 30, 2018, approximately $28 million and $105 million, respectively, was recorded as net loss attributable to noncontrolling interests in NEP's condensed consolidated statements of income as the third-party investors received their portion of the economic attributes of the related facilities. Prior to the adoption, the income related to differential membership interests was being recognized in benefits associated with differential membership interests - net in NEP's condensed consolidated statements of income. Additionally, net loss attributable to noncontrolling interests for the nine months ended September 30, 2018 includes approximately $231 million (after-tax $211 million) related to the reduction of differential membership interests as a result of the change in federal corporate income tax rates effective January 1, 2018.

Noncontrolling Interests - At September 30, 2018 and December 31, 2017, NEP's limited partner interest in NEP OpCo was approximately 35.6% and 34.9%, respectively. At September 30, 2018, NEE's 64.4% noncontrolling interest in NEP OpCo, a non-affiliated party's 10% interest in one of the Texas pipelines and the interests related to differential membership interests discussed above are reflected as noncontrolling interests on the condensed consolidated balance sheets. Details of the activity in noncontrolling interests for the nine months ended September 30, 2018 is below:

	Differential Membership Interests				Noncontrolling Ownership Interests in NEP OpCo and Texas pipeline			Total Noncontrolling Interests

____________________

(a) Represents the benefits associated with differential membership interests recognized as the third-party investors received their portion of the economic attributes of the related facilities. Approximately $219 million of the loss attributable to differential membership interests benefits NEE's noncontrolling interest and $117 million is reflected as net income attributable to NEP.

Leases - In February 2016, the Financial Accounting Standards Board (FASB) issued an accounting standards update which requires, among other things, that lessees recognize a lease liability, initially measured at the present value of the future lease payments, and a right-of-use asset for all leases (with the exception of short-term leases) (new lease standard). The new lease standard also requires new qualitative and quantitative disclosures for both lessees and lessors. The new lease standard will be effective for NEP beginning January 1, 2019. Early adoption is permitted. The new lease standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as an adjustment to retained earnings as of the date of initial application.

NEP is currently reviewing its portfolio of contracts and evaluating the proper application of the new lease standard to these contracts in order to determine the impact the adoption will have on its consolidated financial statements. NEP is implementing a number of system enhancements to facilitate the identification, tracking and reporting of leases based upon the requirements of the new lease standard. NEP is continuing to assess the transition options and practical expedients and monitoring industry implementation issues.

Contracts - At September 30, 2018, NEP and its subsidiaries have entered into contracts with expiration dates ranging from 2018 through 2065 for the sale of differential membership interests related to certain wind generation facilities, engineering, procurement and construction contracts and agreements that provide for the right to use the land upon which certain projects are located.

At September 30, 2018, payments under these contracts were estimated as follows:

Year Ending December 31,	Commitments
	(millions)
Remainder of 2018	$	9
2019	32
2020	32
2021	32
2022	33
Thereafter	455
Total estimated payments	$	593

One of NEP’s solar project's land use agreements includes a right-of-way lease/grant that provides for payments to the BLM for the right to use the public lands upon which the project is located. The lease may be renewed at expiration at the solar project's option and will be subject to the regulations existing at the time of renewal. In connection with the terms of the lease, the solar project obtained a surety bond from a non-affiliated party in favor of the BLM for approximately $23 million. The surety bond remains in effect until the BLM is satisfied that there is no outstanding liability on the bond or satisfactory replacement bond coverage is furnished.

Letter of Credit Facilities - Two of NEP’s projects entered into letter of credit (LOC) facilities under which the LOC lenders may issue standby letters of credit not to exceed approximately $82 million in the aggregate. These LOC facilities have maturity dates of June 2022 and July 2022. At September 30, 2018, approximately $68 million of LOCs was outstanding primarily related to debt service reserves and as security for certain of the projects' agreements, including a PPA.

Acquisition Holdback - At December 31, 2016, the condensed consolidated balance sheets included an acquisition holdback related to the satisfaction of any indemnification obligations of the Texas pipelines sellers through April 2017 (indemnity holdback). During the nine months ended September 30, 2017 the indemnity holdback was released under the terms of the Texas pipelines acquisition agreement and approximately $200 million was paid to the sellers.

Summary of Significant Accounting and Reporting Policies (Policies)

Accounting Policies [Abstract]

Recently Issued Accounting Guidance

Effective January 1, 2018, NEP adopted an accounting standards update that provides guidance on the recognition of revenue from contracts with customers and requires additional disclosures regarding such contracts (new revenue standard). Under the new revenue standard, 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 adopted the new revenue standard using the modified retrospective approach applying it only to contracts that were not complete at January 1, 2018. NEP did not recognize a cumulative effect adjustment on January 1, 2018 because revenue recognized under the new accounting standard remained consistent with historical practice.

NEP's operating revenues are generated primarily from various non-affiliated parties under long-term power purchase agreements, FIT agreements and RESOP agreements (collectively, PPAs) and natural gas transportation agreements. 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. Substantially all of the PPAs are accounted for as operating leases and are not considered contracts with customers within the scope of the new revenue standard.

Leases - In February 2016, the Financial Accounting Standards Board (FASB) issued an accounting standards update which requires, among other things, that lessees recognize a lease liability, initially measured at the present value of the future lease payments, and a right-of-use asset for all leases (with the exception of short-term leases) (new lease standard). The new lease standard also requires new qualitative and quantitative disclosures for both lessees and lessors. The new lease standard will be effective for NEP beginning January 1, 2019. Early adoption is permitted. The new lease standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as an adjustment to retained earnings as of the date of initial application.

NEP is currently reviewing its portfolio of contracts and evaluating the proper application of the new lease standard to these contracts in order to determine the impact the adoption will have on its consolidated financial statements. NEP is implementing a number of system enhancements to facilitate the identification, tracking and reporting of leases based upon the requirements of the new lease standard. NEP is continuing to assess the transition options and practical expedients and monitoring industry implementation issues.

Restricted Cash - In the fourth quarter of 2017, NEP early adopted an accounting standards update which requires that restricted cash be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows. NEP adopted the standards update retrospectively, which adoption did not have a material impact to the condensed consolidated statements of cash flows.

Accounting for Partial Sales of Nonfinancial Assets - Effective January 1, 2018, NEP adopted an accounting standards update regarding the accounting for partial sales of nonfinancial assets using the modified retrospective approach. This standards update affects the accounting and related financial statement presentation for the sales of differential membership interests to third-party investors.
