	SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
	Revenue—Revenue recognized for the three and six months ended June 30, 2014 and 2013, includes revenues from operations located outside of the U.S.  This revenue was approximately $19.0 million and $10.9 million for the three months ended June 30, 2014 and 2013, respectively, and $41.0 million and $17.7 million for the six months ended June 30, 2014 and 2013, respectively.
	In May 2014, the Financial Accounting Standards Board issued a new accounting standard which provides guidance on the recognition of revenue from contracts with customers and requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows from an entity's contracts with customers. The standard is effective for NEP beginning January 1, 2017.  NEP is currently evaluating the effect the adoption of this standard will have, if any, on its financial statements.
	Inventories— Spare parts inventories are stated at the lower of weighted average cost or market and are included in other current assets in NEP’s condensed combined balance sheets.  Spare parts inventory was $5.6 million and $4.3 million as of June 30, 2014 and December 31, 2013, respectively.
	Property, Plant and Equipment, net—Property, plant and equipment consists primarily of development, engineering and construction costs for the renewable energy assets, equipment, land, substations and transmission lines.  Property, plant and equipment, excluding land, is recorded at cost and depreciated on a straight-line basis over their estimated useful lives ranging from three to 30 years, commencing on the date the assets are placed in service.  Maintenance and repairs of property, plant and equipment are charged to operations and maintenance expenses, as incurred.
	Convertible Investment Tax Credits (CITCs) of $595.1 million and $445.1 million as of June 30, 2014 and December 31, 2013, respectively, are recorded as a reduction in property, plant and equipment, net in the condensed combined balance sheets and are amortized as a corresponding reduction to depreciation expense over the estimated life of the related asset. As of June 30, 2014, NEP had recorded a CITC receivable of $24.1 million associated with the Genesis project, which is included in accounts receivable on NEP's condensed combined balance sheets.
	Total net long-lived assets held by operations outside the U.S. amounted to approximately $753.0 million and $625.9 million, respectively, as of June 30, 2014 and December 31, 2013.
	Construction Work in Progress—Construction work in progress includes construction materials, turbine generators, solar panel assemblies and other equipment, third-party engineering costs, capitalized interest and other costs directly associated with the development and construction of the various projects.  Upon commencement of plant operations, costs associated with construction work in progress are transferred to property, plant and equipment, net.
	Construction work in progress decreased and property, plant and equipment, net and CITCs increased at June 30, 2014, primarily due to the second unit of the Genesis facility going into service in March 2014.

	On July 1, 2014, NEP completed its Offering by issuing 18,687,500 common units at a price to the public of $25 per common unit.  The proceeds from the Offering, net of underwriting discounts, commissions and structuring fees, were approximately $438.3 million, of which NEP used approximately $288.3 million to purchase 12,291,593 common units of NEP OpCo from NextEra Energy Equity Partners, LP (NEE Equity) and approximately $150 million to purchase 6,395,907 NEP OpCo common units from NEP OpCo, which will use the net proceeds for general corporate purposes, including to fund future acquisition opportunities.  After the application of the net proceeds from the Offering, NEP owns a 20.1% limited partnership interest in NEP OpCo.
	On July 1, 2014, NEP OpCo and its direct subsidiaries (Loan Parties) entered into a $250 million variable rate, senior secured revolving credit facility that expires in July 2019 (revolving credit facility). The revolving credit facility includes borrowing capacity for letters of credit and incremental commitments to increase the revolving credit facility to up to $1 billion in the aggregate, subject to certain conditions. Borrowings under the revolving credit facility can be used by the Loan Parties to fund working capital and expansion projects, to make acquisitions and for general business purposes. Loans outstanding in U.S. dollars under the revolving credit facility will bear interest at either (i) a base rate, which will be the highest of (x) the federal funds rate plus 0.50%, (y) the administrative agent’s prime rate or (z) the one-month London Interbank Offered Rate (LIBOR) plus 1.0%, in each case, plus an applicable margin; or (ii) one-, two-, three- or six-month LIBOR plus an applicable margin. Loans outstanding in Canadian dollars will bear interest at either (i) a Canadian prime rate, which will be the higher of (x) the Canadian prime rate of a Canadian branch of the administrative agent and (y) the one-month Canadian Dealer Offered Rate (CDOR) plus 1.0%, in each case, plus an applicable margin; or (ii) one-, two-, three- or six-month CDOR plus an applicable margin. The revolving credit facility will be subject to a facility fee ranging from 0.375% to 0.50% per annum depending on NEP OpCo’s leverage ratio (as defined in the revolving credit facility). The revolving credit facility is secured by liens on the assets of NEP OpCo, and certain other assets of, and the ownership interest in, one of its direct subsidiaries, including wind and solar generating facilities with a total generating capability of approximately 990 megawatts. The revolving credit facility contains default and related acceleration provisions relating to the failure to make required payments or to observe other covenants in the revolving credit facility and related documents. Additionally, NEP OpCo and one of its direct subsidiaries are required to comply with certain financial covenants on a quarterly basis and NEP OpCo's ability to pay cash distributions is subject to certain other restrictions. All borrowings under the revolving credit facility are guaranteed by NEP OpCo and NEP, and must be repaid by the end of the revolving credit term.

Long-Term Debt	'
	Long-Term Debt
	During the second quarter of 2014, subsidiaries of NEP issued approximately $280 million principal amount of 5.60% limited-recourse senior secured amortizing notes maturing in September 2038 related to the Genesis project.  The proceeds were used primarily to reimburse NEER for a portion of the costs associated with the construction of the solar thermal generating facility, and are included as noncash activity in NEP's condensed combined statements of cash flows..  The notes are secured by liens on the equity interests in Genesis Solar Funding, LLC and its wholly-owned subsidiary, which indirectly owns the Genesis Solar project, a 250 megawatt utility-scale concentrating solar thermal generating facility located in California.
	In June 2014, subsidiaries of NEP also entered into and borrowed approximately C$170 million (approximately $157 million) under a Canadian limited-recourse senior secured variable rate term loan agreement related to its Bluewater project that matures in 2032.  Interest on the loan is based on the applicable Canadian Dealer Offered Rate plus a specified margin and is payable quarterly.  Principal on the loan will be payable semi-annually.  In connection with the borrowing, Bluewater entered into an interest rate swap to hedge against interest rate movements with respect to substantially all interest payments on the loan. Substantially all of the loan proceeds were used to repay, in part, a loan from a Canadian subsidiary of NEER, and are included as noncash activity in NEP's condensed combined statements of cash flows.  The loan is secured by liens on the wind generating facility's assets and certain other assets of, and the ownership interest in, Bluewater, which owns the facility.
	Both debt agreements contain default and related acceleration provisions relating to the failure to make required payments or to observe other covenants in the loan agreement and related documents, actions by the NEP subsidiaries or by other parties under specified agreements relating to the generating facility or the debt agreements, the termination of certain of such specified agreements and certain bankruptcy-related events.

Derivative Instruments and Hedging Activity	'
	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITY
	NEP recognizes all derivative instruments, when required to be marked to market, on the balance sheet as either assets or liabilities and measures them at fair value each reporting period. In connection with its debt financings in September 2012 and June 2014, NEP entered into interest rate swap agreements to manage interest rate cash flow risk.  Under the interest rate swap agreements, NEP pays a fixed rate of interest and receives a floating rate of interest over the term of the agreements without the exchange of the underlying notional amounts.  These agreements allow NEP to offset the variability of its floating-rate loan interest cash flows with the variable interest cash flows received from the interest rate swap agreements.  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, which mature in 2030 and 2032.  As of June 30, 2014 and December 31, 2013, the combined notional amounts of the swap agreements were approximately $355.7 million and $211.8 million, respectively.  In order to apply hedge accounting, the transactions must be designated as hedges and must be highly effective in offsetting the hedged risk.  For interest rate swaps, generally NEP assesses a hedging instrument’s effectiveness by using non-statistical methods including dollar value comparisons of the change in the fair value of the derivative to the change in the fair value or cash flows of the hedged item.  Hedge effectiveness is tested at the inception of the hedge and on at least a quarterly basis throughout the hedge’s life.  The effective portion of changes in the fair value of derivatives accounted for as cash flow hedges are deferred and recorded as a component of accumulated other comprehensive income (AOCI).  The amounts deferred in AOCI are recognized in earnings when the hedged transactions occur.  Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss, is reported in current earnings.
	Approximately $5.1 million of net losses included in AOCI at June 30, 2014, is expected to be reclassified into interest expense within the next 12 months as interest payments are made.  Such amount assumes no change in interest rates.  Cash flows from these interest rate swap contracts are reported in cash flows from operating activities in NEP's condensed combined statements of cash flows.
	The fair values of NEP's derivative instruments designated as cash flow hedging instruments are included in NEP's condensed combined balance sheets as follows:

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 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 fair value measurement of its assets and liabilities and 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.  All transfers between fair value hierarchy levels occur at the beginning of the period in which the transfer occurred.
	Cash Equivalents and Restricted Cash — Cash equivalents and restricted cash consist of short-term, highly liquid investments with original maturities of three months or less.  NEP primarily holds these investments in money market funds.  The fair value of these funds is calculated using current market prices.
	Interest Rate Swaps — NEP estimates the fair value of its derivatives using a discounted cash flows valuation technique based on the net amount of estimated future cash inflows and outflows related to the swap agreements.  The primary inputs used in the fair value measurements include the contractual terms of the derivative agreements, current interest rates and credit spreads.
	NEP’s financial assets and liabilities and other fair value measurements made on a recurring basis by fair value hierarchy level are as follows:

	INCOME TAXES
	The effective tax rate for the three months ended June 30, 2014 and 2013, is 17.5% and 44.7%, respectively and for the six months ended June 30, 2014 and 2013 is 28.0% and 60.5%, respectively.  The effective tax rate is affected by recurring items, such as the relative amount of income earned in jurisdictions, the 50% tax basis reduction due to CITCs that are recognized when assets are placed into service, and valuation allowances on deferred tax assets.
	A reconciliation of income tax at the U.S. federal statutory rate to income tax expense is as follows:

Intangible Liabilities	'
	INTANGIBLE LIABILITIES
	NEP’s intangible liabilities are the result of an acquisition in 2012.  That acquisition resulted in the St. Clair project assuming liabilities for the acquired RESOP Contracts.  The acquired value represents the fair value of the RESOP Contracts, which were out-of-the-money contracts, at the acquisition date.  The recorded intangible liabilities are amortized to operating revenues over the term of the RESOP Contracts through February 2032, according to the cash flow benefits or detriments associated with the contracts as determined at acquisition.  The liabilities as of June 30, 2014 and December 31, 2013 were $8.1 million and $8.3 million, respectively and are included in other non-current liabilities in the accompanying condensed combined balance sheets.  NEP recorded $0.1 million and $0.1 million of amortization for the three months ended June 30, 2014 and 2013, respectively, and $0.2 million and $0.3 million for the six months ended June 30, 2014 and 2013, respectively.  Estimated amortization over the next five years is approximately $0.5 million in each year.

	COMMITMENTS AND CONTINGENCIES
	Land Use Commitments — The project owners are parties to various agreements that provide for payments to landowners for the right to use the land upon which the projects are located.  These leases and easements can typically be renewed by the Project Owners for numerous terms.  The annual fees range from minimum rent payments varying by lease to maximum rent payments of a certain percentage of gross revenues, varying by lease.  Total lease expense was $2.9 million and $1.6 million for the three months ended June 30, 2014 and 2013, respectively and $5.5 million and $4.3 million for the six months ended, respectively, and is classified as operations and maintenance expenses in NEP's accompanying condensed combined statements of operations and comprehensive income (loss).
	Genesis’ land leases include a right-of-way lease/grant that provides for payments to the U.S. Bureau of Land Management (BLM) for the right to use the public lands upon which the project is located.  The lease may be renewed at expiration at Genesis’ option and will be subject to the regulations existing at the time of renewal.  As required by the terms of this lease, Genesis obtained a surety bond in favor of BLM for $23 million.  The surety bond will remain in effect until the BLM is satisfied that there is no outstanding liability on the bond or satisfactory replacement bond coverage is obtained.
	As the base rent and the MW capacity fee payable to the BLM are both based on fair value, these payments are considered contingent rent and, therefore, expense is recognized as incurred.
	The total minimum rental commitments at June 30, 2014 under these land use agreements are as follows:
	Year Ending December 31,	Land Use
		Commitments
		(millions)
	2014 (Remaining)	$	1.9

	2017	4
	2018	4.1
	Thereafter	116.9
	Total minimum land use payments	$	134.8
	Development, Engineering, and Construction Commitments — Certain projects have several open engineering, procurement and construction (EPC) contracts procured to develop, engineer and construct the various solar- and wind-power generating facilities.  Those contracts have varying payment terms and some include performance obligations that allow the companies to receive liquidated damages if the contractor does not perform.  During the three months ended June 30, 2014, the projects purchased $27.2 million under these contracts, which costs have been capitalized in construction work in progress.  At June 30, 2014, Bluewater had several open EPC contracts related to the procurement of materials and services for the related projects.  As of June 30, 2014, total contract commitments were $222.6 million and the remaining commitment was $10.1 million.
	Letter of Credit Facility — Genesis entered into a letter of credit (LOC) facility (LOC facility), under which the LOC lender may issue standby letters of credit not to exceed $82.9 million, with a maturity date of August 15, 2017.
	The purpose and amounts of letters of credit outstanding as of June 30, 2014 are as follows:

Revenue	'
	Revenue—Revenue recognized for the three and six months ended June 30, 2014 and 2013, includes revenues from operations located outside of the U.S.
Inventory	'
	Inventories— Spare parts inventories are stated at the lower of weighted average cost or market and are included in other current assets in NEP’s condensed combined balance sheets.
Property, Plant and Equipment, net and Construction Work in Progress	'
	Property, Plant and Equipment, net—Property, plant and equipment consists primarily of development, engineering and construction costs for the renewable energy assets, equipment, land, substations and transmission lines.  Property, plant and equipment, excluding land, is recorded at cost and depreciated on a straight-line basis over their estimated useful lives ranging from three to 30 years, commencing on the date the assets are placed in service.  Maintenance and repairs of property, plant and equipment are charged to operations and maintenance expenses, as incurred.
	Construction Work in Progress—Construction work in progress includes construction materials, turbine generators, solar panel assemblies and other equipment, third-party engineering costs, capitalized interest and other costs directly associated with the development and construction of the various projects.  Upon commencement of plant operations, costs associated with construction work in progress are transferred to property, plant and equipment, net.
Convertible Investment Tax Credits	'
	Convertible Investment Tax Credits (CITCs) of $595.1 million and $445.1 million as of June 30, 2014 and December 31, 2013, respectively, are recorded as a reduction in property, plant and equipment, net in the condensed combined balance sheets and are amortized as a corresponding reduction to depreciation expense over the estimated life of the related asset.
Hedge Effectiveness	'
	In order to apply hedge accounting, the transactions must be designated as hedges and must be highly effective in offsetting the hedged risk.  For interest rate swaps, generally NEP assesses a hedging instrument’s effectiveness by using non-statistical methods including dollar value comparisons of the change in the fair value of the derivative to the change in the fair value or cash flows of the hedged item.  Hedge effectiveness is tested at the inception of the hedge and on at least a quarterly basis throughout the hedge’s life.  The effective portion of changes in the fair value of derivatives accounted for as cash flow hedges are deferred and recorded as a component of accumulated other comprehensive income (AOCI).  The amounts deferred in AOCI are recognized in earnings when the hedged transactions occur.  Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss, is reported in current earnings.
