Accounting Policies [Abstract]
NextEra Energy Partners, LP	NextEra Energy Partners, LP - In February and March 2016, NEP completed the sale of 11,155,000 common units representing limited partnership interests in NEP in a public offering for an aggregate purchase price of approximately $287 million, or $25.76 per common unit. This offering, together with issuances of additional common units under NEP's at-the-market equity issuance program during the three months ended March 31, 2016, resulted in a decrease of NEE’s interest in NEP's operating projects to approximately 70.8% at March 31, 2016.
Leases	Leases - In February 2016, the 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). The standards update will be effective for NEE and FPL beginning January 1, 2019. Early adoption is permitted. Lessees and lessors must apply a modified retrospective approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. NEE and FPL are currently evaluating the effect the adoption of this standards update will have on their consolidated financial statements.
Stock-Based Compensation	Stock-Based Compensation - In March 2016, the FASB issued an accounting standards update related to the accounting for employee share-based payment awards including simplification in areas such as (i) income tax consequences; (ii) classification of awards as either equity or liabilities; and (iii) classification on the statement of cash flows. The standards update will be effective for NEE and FPL beginning January 1, 2017. Early adoption is permitted and each provision has specific adoption methods required within the standards update. NEE and FPL are currently evaluating the effect the adoption of this standards update will have on their consolidated financial statements.
Assets and Liabilities Associated with Assets Held for Sale	Assets and Liabilities Associated with Assets Held for Sale - On April 4, 2016, a subsidiary of NEER completed the sale of its ownership interest in merchant natural gas generation facilities located in Texas with a total generating capacity of 2,884 MW for net cash proceeds of approximately $456 million, after transaction costs and working capital adjustments. A NEER affiliate will continue to operate the facilities included in the sale for an initial period of up to one year. In connection with the sale and the related consolidating state income tax effects, a gain of approximately $254 million ($107 million after tax) will be recorded in NEE's condensed consolidated statements of income during the three-months ended June 30, 2016. The carrying amounts of the major classes of assets and liabilities related to the facilities that were classified as held for sale on NEE's condensed consolidated balance sheets at March 31, 2016 and December 31, 2015 primarily represent property, plant and equipment and the long-term debt associated with the facilities.

Disclosure of accounting policy for leasing arrangements (both lessor and lessee). This disclosure may address (1) lease classification (that is, operating versus capital), (2) how the term of a lease is determined (for example, the circumstances in which a renewal option is considered part of the lease term), (3) how rental revenue or expense is recognized for a lease that contains rent escalations, (4) an entity's accounting treatment for deferred rent, including that which arises from lease incentives, rent abatements, rent holidays, or tenant allowances (5) an entity's accounting treatment for contingent rental payments and (6) an entity's policy for reviewing, at least annually, the residual values of sales-type and direct-finance leases. The disclosure also may indicate how the entity accounts for its capital leases, leveraged leases or sale-leaseback transactions.
