	ORGANIZATION AND NATURE OF BUSINESS
	NEP was formed as a Delaware limited partnership on March 6, 2014 as an indirect wholly-owned subsidiary of NEE, a Florida corporation.  NEP was formed to be a growth-oriented limited partnership that would own, operate and acquire clean and contracted generation assets with stable long-term cash flows.
	On July 1, 2014, NEP completed its initial public offering by issuing 18,687,500 common units at a price to the public of $25 per unit (offering).  The proceeds from the offering, net of underwriting discounts, commissions and structuring fees, were approximately $438 million, of which NEP used approximately $288 million to purchase 12,291,593 common units of NEP OpCo from NextEra Energy Equity Partners, LP (NEE Equity), a limited partnership formed under the laws of the State of Delaware and an indirect wholly-owned subsidiary of NEE, and approximately $150 million to purchase 6,395,907 NEP OpCo common units from NEP OpCo, which will use that amount for general partnership purposes, including to fund future acquisition opportunities.
	NEP OpCo is a limited partnership with general and limited partners.  As a result of the offering, NEP has consolidated the results of NEP OpCo and its subsidiaries because of its controlling interest in the general partner of NEP OpCo.  NEP owns a 20.1% limited partnership interest in NEP OpCo and NEE Equity owns a noncontrolling 79.9% limited partnership interest in NEP OpCo.
	In connection with the offering, NEP acquired the following portfolio of clean, contracted renewable energy assets (initial portfolio):

	For all periods prior to the offering, the accompanying unaudited condensed consolidated financial statements represent the combination of the assets that NEP acquired and were prepared using NEE’s historical basis in the assets and liabilities.  For all periods subsequent to the offering, the accompanying unaudited condensed consolidated financial statements represent the consolidated results of NEP.
	In October 2014, indirect subsidiaries of NEP OpCo entered into agreements to expand NEP's portfolio through two project acquisitions from NEER that are expected to close in the first quarter of 2015.
	The Palo Duro acquisition is for 100% of the membership interests of Palo Duro Wind Project Holdings, LLC, which immediately prior to the Palo Duro closing will own 100% of the Class A membership interests in Palo Duro Wind Energy, LLC, a project company owning the development rights and facilities under construction of an approximately 250 megawatt wind energy generating facility located in Hansford and Ochiltree Counties, Texas (the transaction), for approximately $227 million, subject to customary working capital and other adjustments.  Prior to the Palo Duro transaction, certain tax equity investors will make certain upfront capital contributions and acquire 100% of the Class B membership interests in Palo Duro Wind Energy, LLC.  The tax equity investors will also make ongoing deferred contingent capital contributions based on the production and sale of electricity that generates production tax credits under Section 45 of the Internal Revenue Code of 1986, as amended.  Immediately following the Palo Duro closing, Palo Duro Wind Project Holdings, LLC will hold 100% of the Class A membership interests in Palo Duro Wind Energy, LLC, and the tax equity investors will hold 100% of the Class B membership interests in Palo Duro Wind Energy, LLC.  The transaction is subject to customary closing conditions, consummation of the tax equity financing and the receipt of certain regulatory approvals.  The Palo Duro purchaser expects the transaction to close in January 2015, and intends to fund the purchase price through a combination of cash on hand and draws on the existing revolving credit facility.
	The Shafter acquisition is for 100% of the membership interests of Shafter Solar, LLC, which owns the development rights and facilities under construction of an approximately 20 megawatt solar generating facility located in Shafter, California for approximately $64 million, subject to customary working capital and other adjustments.  The Shafter purchaser expects the transaction to close in the first quarter of 2015, and intends to fund the purchase price through a combination of cash on hand and draws on the existing revolving credit facility.

Accounting Policies [Abstract]	'
Summary of Significant Accounting and Reporting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
	Revenue—Revenue recognized for the three and nine months ended September 30, 2014 and 2013, includes operating revenues from operations located outside of the U.S.  This revenue was approximately $20 million and $13 million for the three months ended September 30, 2014 and 2013, respectively, and $61 million and $31 million for the nine months ended September 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 consolidated balance sheets.  Spare parts inventory was approximately $6 million and $4 million as of September 30, 2014 and December 31, 2013, respectively.
	Property, Plant and Equipment—net and Construction Work in Progress—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 expense, as incurred.
	Convertible Investment Tax Credits (CITCs) of approximately $595 million and $445 million as of September 30, 2014 and December 31, 2013, respectively, are recorded as a reduction in property, plant and equipment—net in the condensed consolidated balance sheets and are amortized as a corresponding reduction to depreciation expense over the estimated life of the related asset.  As of September 30, 2014, NEP had recorded a CITC receivable of approximately $24 million associated with the Genesis Solar project which is included in accounts receivable on NEP's condensed consolidated balance sheets.
	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 September 30, 2014, primarily due to the second unit of the Genesis Solar project and the Bluewater project going into service in March 2014 and July 2014, respectively.
	Total net long-lived assets, including construction work in progress, held by operations outside the U.S. amounted to approximately $724 million and $626 million, respectively, as of September 30, 2014 and December 31, 2013.
	Immaterial Restatement—Subsequent to the issuance of NEP's combined financial statements as of December 31, 2013, it was determined that Income tax expense and Other comprehensive loss for the year ended December 31, 2013 were overstated by approximately $4 million and $1 million, respectively, and the Deferred tax liability balance as of December 31, 2013 was overstated by approximately $5 million.  The impact of this error had no impact on cash flows from operating, investing or financing activities. As a result, the prior periods in the accompanying financial statements have been corrected to appropriately reflect these balances in the condensed consolidated statements of income, condensed consolidated statements of comprehensive income, condensed consolidated balance sheets, condensed consolidated statements of cash flows, Note 2, Note 3 and Note 8.
	Noncontrolling Interests—After the completion of NEP's offering, NEP owns a controlling, non-economic general partner interest and a 20.1% limited partner interest in NEP OpCo and NEE Equity owns a noncontrolling 79.9% limited partner interest in NEP OpCo.  The following table reflects the changes in NEP's noncontrolling interest balance for the three and nine months ended September 30, 2014:
		Noncontrolling
		Interest
		(in millions)
	Noncontrolling interest at December 31, 2013 and June 30, 2014	$	—
	Contributions from noncontrolling interest, net of returns of capital	171
	Comprehensive income attributable to noncontrolling interest	14
	Noncontrolling interest at September 30, 2014	$	185
	The contributions from NEP's offering primarily reflect the value of the underlying net assets sold to third parties in NEP's offering.
	Cash Flows—Following the offering, NEP will present transactions with related parties where it does not directly receive the cash as cash transactions on its condensed consolidated statement of cash flows.

Income Taxes	'
	INCOME TAXES
	For periods ending prior to July 1, 2014, income taxes are calculated using the separate return method for each of the project entities that are structured as corporations or as limited liability companies electing to be taxed as corporations.  Income taxes are not included for entities that are structured as flow through entities (partnerships) electing to be taxed as partnerships.
	For periods ending after July 1, 2014, taxes are calculated for NEP as a single taxpaying entity for U.S. federal and state income tax purposes (based on its election to be taxed as a corporation).  Because NEP OpCo is a limited partnership electing to be taxed as a partnership for U.S. federal and state income tax purposes, NEP has only included its 20.1% proportionate share of U.S. income taxes.  The U.S. income taxes on the remaining 79.9% of NEP OpCo earnings were allocated to NEE Equity and are not included in NEP's condensed consolidated financial statements.  The Canadian subsidiaries are all Canadian taxpayers subject to Canadian income tax, and therefore all Canadian taxes are included in NEP's condensed consolidated financial statements.  NEE Equity's share of Canadian taxes is included in noncontrolling interest on NEP's condensed financial statements.
	The effective tax rate for the three months ended September 30, 2014 and 2013 was approximately 8% and (100%), respectively and for the nine months ended September 30, 2014 and 2013, approximately 20% and 56%, 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.  Additionally, in periods ending after July 1, 2014, the effective tax rate is affected by taxes attributable to the noncontrolling interest, and the taxation of Canadian income in both Canada and the U.S.
	A reconciliation of income tax at the U.S. federal statutory rate to income tax expense is as follows:
		Three Months Ended						Nine Months Ended
		September 30,						September 30,
		2014			2013			2014			2013

	Income tax expense	$	2		$	1		$	13		$	10
	____________________
	(a)	The changes in income tax expense resulting from CITCs and valuation allowances are primarily related to the Genesis Solar project.
	(b)	The Summerhaven and Conestogo project entities, as well as the Trillium entities, are Canadian limited partnerships, the partners of which are not predecessor entities and are therefore not included in the predecessor financial statements.  Because of their flow through nature, no income taxes have been provided with regard to these entities for periods ending prior to July 1, 2014.  Foreign tax differential is the difference in taxes calculated on Canadian income from Canadian projects (excluding flow through entities for periods ending prior to July 1, 2014) at Canadian statutory rates compared to the U.S. statutory rate.

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 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:

	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 September 30, 2014 and December 31, 2013, the combined notional amounts of the swap agreements were approximately $344 million and $212 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 million of net losses included in AOCI at September 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 consolidated statements of cash flows.
	The fair values of NEP's derivative instruments designated as cash flow hedging instruments are included in NEP's condensed consolidated balance sheets as follows:

Long-Term Debt	'
	DEBT
	During the second quarter of 2014, a NEP subsidiary issued $280 million principal amount of 5.60% limited-recourse senior secured amortizing notes maturing in September 2038 related to the Genesis Solar project.  The proceeds were used primarily to reimburse NEER for a portion of the costs associated with the construction of the Genesis Solar project, and are included as noncash activity in NEP's condensed consolidated 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.
	In June 2014, subsidiaries of NEP also entered into and borrowed C$170 million (approximately $157 million dollar equivalent as of the date of the borrowing) 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 (CDOR) 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 consolidated statements of cash flows. The loan is secured by liens on the Bluewater project's assets and certain other assets of, and the ownership interest in, the subsidiary 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.
	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.  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 higher 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 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 certain of the assets of NEP OpCo, and certain other assets of, and the ownership interest in, one of its direct subsidiaries.  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.  As of November 11, 2014, no amounts have been drawn under the revolving credit facility.

	Each project entered into operations and maintenance (O&M) and administrative services agreements with subsidiaries of NEER whereby the projects pay a certain annual fee plus actual costs incurred in connection with O&M and administrative services performed under these agreements.  NEP’s O&M expenses for the three months ended September 30, 2014 and 2013 include approximately $1 million and less than $1 million, respectively, and approximately $3 million and $1 million for the nine months ended September 30, 2014 and 2013, respectively, related to such services.  Additionally, Northern Colorado Wind Energy, LLC pays an affiliate for transmission services.  NEP’s transmission expense for the three and nine months ended September 30, 2014 and 2013 represents the fees paid for these services.
	Management Services Agreement (MSA) - Effective July 1, 2014, subsidiaries of NEP entered into a MSA with indirect wholly owned subsidiaries of NEE, under which operational, management and administrative services are provided to NEP, including managing NEP’s day to day affairs and providing individuals to act as NEP GP’s executive officers and directors, in addition to those services that are provided under the existing O&M agreements and administrative services agreements described above between NEER subsidiaries and NEP subsidiaries.  NEP OpCo will pay NEE an annual management fee equal to the greater of 1% of NEP OpCo’s EBITDA for the most recently ended fiscal year and $4 million (as adjusted for inflation beginning in 2016), which will be paid in quarterly installments of $1 million with an additional payment each January to the extent 1% of NEP OpCo’s annual EBITDA for the preceding fiscal year exceeds $4 million (as adjusted for inflation beginning in 2016).  NEP OpCo will also make certain payments to NEE based on the achievement by NEP OpCo of certain target quarterly distribution levels to its unitholders (incentive distribution rights, or IDRs).  NEP’s O&M expenses for the three and nine months ended September 30, 2014 include $1 million related to payments made under the MSA.  There was no expense for the three and nine months ended September 30, 2013 related to the MSA.
	Cash Sweep and Credit Support Agreement - Effective July 1, 2014, NEP OpCo entered into a cash sweep and credit support 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 interest expense for the three and nine months ended September 30, 2014 includes less than $1 million each related to payments made under the cash sweep and credit support agreement.  There was no expense for the three and nine months ended September 30, 2013 related to the credit support agreement.
	In addition, under this agreement, NEER and certain of its subsidiaries may withdraw funds received by NEP or its subsidiaries, including NEP OpCo, 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’ financings, the lenders will be entitled to draw on 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.  The cash sweep amounts held in accounts belonging to NEER or its subsidiaries as of September 30, 2014 and 2013, were approximately $182 million and $0, respectively, and are included in due from related parties in NEP’s condensed consolidated balance sheets.

	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 various periods.  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 approximately $3 million and $2 million for the three months ended September 30, 2014 and 2013, respectively, and approximately $8 million and $6 million for the nine months ended September 30, 2014 and 2013, respectively, and is classified as operations and maintenance expenses in NEP's accompanying condensed consolidated statements of operations and comprehensive income (loss).
	The Genesis Solar project's land lease includes 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 the Genesis Solar project's option and will be subject to the regulations existing at the time of renewal.  As required by the terms of this lease, the Genesis Solar project obtained a surety bond in favor of BLM for approximately $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 September 30, 2014 under these land use agreements are as follows:

Accounting Policies [Abstract]	'
Revenue	'
	Revenue—Revenue recognized for the three and nine months ended September 30, 2014 and 2013, includes operating revenues from operations located outside of the U.S.
New Accounting Pronouncements	'
	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.
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 consolidated balance sheets.
Property, Plant and Equipment, net and Construction Work in Progress	'
	Property, Plant and Equipment—net and Construction Work in Progress—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 expense, as incurred.
	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 approximately $595 million and $445 million as of September 30, 2014 and December 31, 2013, respectively, are recorded as a reduction in property, plant and equipment—net in the condensed consolidated 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.

[2]	Summerhaven and Conestogo project entities, as well as the Trillium entities, are Canadian limited partnerships, the partners of which are not predecessor entities and are therefore not included in the predecessor financial statements. Because of their flow through nature, no income taxes have been provided with regard to these entities for periods ending prior to July 1, 2014. Foreign tax differential is the difference in taxes calculated on Canadian income from Canadian projects (excluding flow through entities for periods ending prior to July 1, 2014) at Canadian statutory rates compared to the U.S. statutory rate.
