Variable Interest Entities [Abstract]
Variable Interest Entities (VIEs)	Variable Interest Entities (VIEs) At March 31, 2019, NEE had 31 VIEs which it consolidated and had interests in certain other VIEs which it did not consolidate. FPL - FPL is considered the primary beneficiary of, and therefore consolidates, a VIE that is a wholly owned bankruptcy remote special purpose subsidiary that it formed in 2007 for the sole purpose of issuing storm-recovery bonds pursuant to the securitization provisions of the Florida Statutes and a financing order of the FPSC. FPL is considered the primary beneficiary because FPL has the power to direct the significant activities of the VIE, and its equity investment, which is subordinate to the bondholder's interest in the VIE, is at risk. Storm restoration costs incurred by FPL during 2005 and 2004 exceeded the amount in FPL's funded storm and property insurance reserve, resulting in a storm reserve deficiency. In 2007, the VIE issued $652 million aggregate principal amount of senior secured bonds (storm-recovery bonds), primarily for the after-tax equivalent of the total of FPL's unrecovered balance of the 2004 storm restoration costs, the 2005 storm restoration costs and to reestablish FPL's storm and property insurance reserve. In connection with this financing, net proceeds, after debt issuance costs, to the VIE (approximately $644 million) were used to acquire the storm-recovery property, which includes the right to impose, collect and receive a storm-recovery charge from all customers receiving electric transmission or distribution service from FPL under rate schedules approved by the FPSC or under special contracts, certain other rights and interests that arise under the financing order issued by the FPSC and certain other collateral pledged by the VIE that issued the bonds. The storm-recovery bonds are payable only from and are secured by the storm-recovery property. The bondholders have no recourse to the general credit of FPL. The assets of the VIE were approximately $35 million and $77 million at March 31, 2019 and December 31, 2018, respectively, and consisted primarily of storm-recovery property, which are included in current regulatory assets on NEE's and FPL's condensed consolidated balance sheets. The liabilities of the VIE were approximately $36 million and $76 million at March 31, 2019 and December 31, 2018, respectively, and consisted primarily of storm-recovery bonds, which are included in current portion of long-term debt on NEE's and FPL's condensed consolidated balance sheets. NEER - NEE consolidates 29 NEER VIEs. NEER is considered the primary beneficiary of these VIEs since NEER controls the most significant activities of these VIEs, including operations and maintenance, and has the obligation to absorb expected losses of these VIEs. NEER consolidates two VIEs, which own and operate natural gas/oil electric generation facilities with the capability of producing 1,450 MW. These entities sell their electric output under power sales contracts to third parties, with expiration dates in 2021 and 2031. The power sales contracts provide the offtaker the ability to dispatch the facilities and require the offtaker to absorb the cost of fuel. The assets and liabilities of these two VIEs were approximately $218 million and $18 million, respectively, at March 31, 2019. These two VIEs, together with a third VIE that consolidated two separate NEER entities, collectively had assets and liabilities that totaled $257 million and $21 million, respectively, at December 31, 2018. At March 31, 2019 and December 31, 2018, the assets of these consolidated VIEs consisted primarily of property, plant and equipment. Two indirect subsidiaries of NEER each contributed, to a NEP subsidiary, an approximately 50% ownership interest in three entities which own and operate solar PV facilities with the capability of producing a total of approximately 277 MW. Each of the two indirect subsidiaries of NEER is considered a VIE since the non-managing members have no substantive rights over the managing members, and is consolidated by NEER. These three entities sell their electric output to third parties under power sales contracts with expiration dates in 2035 and 2036. The three entities have third-party debt which is secured by liens against the assets of the entities. The debt holders have no recourse to the general credit of NEER for the repayment of debt. The assets and liabilities of these VIEs were approximately $492 million and $542 million, respectively, at March 31, 2019 and $529 million and $557 million, respectively, at December 31, 2018, and consisted primarily of property, plant and equipment and long-term debt. The other 25 NEER VIEs that are consolidated relate to certain subsidiaries which have sold differential membership interests in entities which own and operate wind electric generation and solar PV facilities with the capability of producing a total of approximately 7,081 MW and 473 MW, respectively. These entities sell their electric output either under power sales contracts to third parties with expiration dates ranging from 2019 through 2053 or in the spot market. These entities are considered VIEs because the holders of differential membership interests do not have substantive rights over the significant activities of these entities. Certain entities have third-party debt which is secured by liens against the generation facilities and the other assets of these entities or by pledges of NEER's ownership interest in these entities. The debt holders have no recourse to the general credit of NEER for the repayment of debt. The assets and liabilities of these VIEs consisted primarily of property, plant and equipment and long-term debt and totaled approximately $10.2 billion and $1.4 billion, respectively, at March 31, 2019, including amounts classified as held for sale (see Note 11 - Assets and Liabilities Associated with Assets Held for Sale), and $10.2 billion and $1.4 billion, respectively, at December 31, 2018. In February 2018, NEER sold a special purpose entity for net cash proceeds of approximately $71 million. In connection with the sale, a gain of approximately $50 million (approximately $37 million after tax) was recorded in gains on disposal of investments and other property - net in NEE's condensed consolidated statements of income during the three months ended March 31, 2018. Other - At March 31, 2019 and December 31, 2018, several NEE subsidiaries had investments totaling approximately $2,885 million ($2,396 million at FPL) and $2,668 million ($2,203 million at FPL), respectively, which are included in special use funds and noncurrent other assets on NEE's condensed consolidated balance sheets and in special use funds on FPL's condensed consolidated balance sheets. These investments represented primarily commingled funds and mortgage-backed securities. NEE subsidiaries, including FPL, are not the primary beneficiaries and therefore do not consolidate any of these entities because they do not control any of the ongoing activities of these entities, were not involved in the initial design of these entities and do not have a controlling financial interest in these entities. Certain subsidiaries of NEE have noncontrolling interests in entities accounted for under the equity method, including NEE's noncontrolling interest in NEP OpCo. These entities are limited partnerships or similar entity structures in which the limited partners or nonmanaging members do not have substantive rights, and therefore are considered VIEs. NEE is not the primary beneficiary because it does not have a controlling financial interest in these entities, and therefore does not consolidate any of these entities. NEE’s investment in these entities totaled approximately $4,504 million and $4,680 million at March 31, 2019 and December 31, 2018, respectively. Subsidiaries of NEE had committed to invest an additional approximately $55 million in three of these entities at both March 31, 2019 and December 31, 2018. Beginning in the first quarter of 2019, NEE consolidates a NEET subsidiary, which is considered a VIE since NEET is the primary beneficiary and controls the most significant activities during the period in which the subsidiary is constructing an approximately 275-mile electricity transmission line, including controlling the construction budget. Prior to the construction period, the entity was jointly controlled and was accounted for under the equity method. NEET is entitled to receive 50% of profits and losses of the entity. At March 31, 2019, the assets and liabilities of the VIE totaled $68 million and $7 million, respectively.
