Revenue Recognition

Revenue Recognition	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue from Contracts with Customers FPL and NEER generate substantially all of NEE’s operating revenues, which primarily include revenues from contracts with customers, as well as derivative and lease transactions at NEER. For the vast majority of contracts with customers, NEE believes that the obligation to deliver energy, capacity or transmission is satisfied over time as the customer simultaneously receives and consumes benefits as NEE performs. For the three months ended March 31, 2019 and 2018 , NEE’s revenue from contracts with customers was approximately $3.8 billion ( $2.6 billion at FPL) and $3.6 billion ( $2.6 billion at FPL), respectively. NEE's and FPL's receivables are primarily associated with revenues earned from contracts with customers, as well as derivative and lease transactions at NEER, and consist of both billed and unbilled amounts, which are recorded in customer receivables and other receivables on NEE's and FPL's condensed consolidated balance sheets. Receivables represent unconditional rights to consideration and reflect the differences in timing of revenue recognition and cash collections. For substantially all of NEE's and FPL'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. FPL - FPL’s revenues are derived primarily from tariff-based sales that result from providing electricity to retail customers in Florida with no defined contractual term. Electricity sales to retail customers account for approximately 90% of FPL’s operating revenues, the majority of which are to residential customers. FPL’s retail customers receive a bill monthly based on the amount of monthly kWh usage with payment due monthly. For these types of sales, FPL recognizes revenue as electricity is delivered and billed to customers, as well as an estimate for electricity delivered and not yet billed. The billed and unbilled amounts represent the value of electricity delivered to the customer. At March 31, 2019 and December 31, 2018 , FPL's unbilled revenues amounted to approximately $442 million and $432 million , respectively, and are included in customer receivables on NEE's and FPL's condensed consolidated balance sheets. NEER - NEER’s revenue from contracts with customers is derived primarily from the sale of energy commodities, electric capacity and electric transmission. For these types of sales, NEER recognizes revenue as energy commodities are delivered and as electric capacity and electric transmission are made available, consistent with the amounts billed to customers based on rates stipulated in the respective contracts as well as an accrual for amounts earned but not yet billed. The amounts billed and accrued represent the value of energy or transmission delivered and/or the capacity of energy or transmission available to the customer. Revenues yet to be earned under these contracts, which have maturity dates ranging from 2019 to 2053 , will vary based on the volume of energy or transmission delivered and/or available. NEER’s customers typically receive bills monthly with payment due within 30 days. Certain contracts with customers contain a fixed price related primarily to electric capacity sales associated with ISO annual auctions through 2020 and certain power purchase agreements with maturity dates through 2034. At March 31, 2019 , NEER expects to record approximately $890 million of revenues related to the fixed price components of such contracts over the remaining terms of the related contracts as the capacity is provided.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
NEP	NEP NEP was deconsolidated from NEE for financial reporting purposes in January 2018 as a result of changes made to NEP's governance structure during 2017 that, among other things, enhanced NEP common unitholder governance rights. In connection with the deconsolidation, NEE recorded an initial investment in NEP of approximately $4.4 billion based on the fair value of NEP OpCo and NEP common units that were held by subsidiaries of NEE on the deconsolidation date, which investment is included in the investment in equity method investees on NEE's condensed consolidated balance sheets. The fair value was based on the market price of NEP common units as of January 1, 2018, which resulted in NEE recording a gain of approximately $3.9 billion ( $3.0 billion after tax) during the three months ended March 31, 2018 . NEER continues to operate the projects owned by NEP. NEER provides management, administrative and transportation and fuel management services to NEP and its subsidiaries under various agreements (service agreements). NEER is also party to a cash sweep and credit support (CSCS) agreement with a subsidiary of NEP. At March 31, 2019 and December 31, 2018 , the cash sweep amounts (due to NEP and its subsidiaries) held in accounts belonging to NEER or its subsidiaries was approximately $42 million and $66 million , respectively, and is included in accounts payable. Fee income totaling approximately $24 million and $24 million related to the CSCS agreement and the service agreements is included in operating revenues in NEE's condensed consolidated statements of income for the three months ended March 31, 2019 and 2018 , respectively. Amounts due from NEP of approximately $46 million and $45 million are included in other receivables and $58 million and $34 million are included in noncurrent other assets at March 31, 2019 and December 31, 2018 , respectively. Under the CSCS agreement, NEECH or NEER guaranteed or provided indemnifications, letters of credit or bonds totaling approximately $761 million at March 31, 2019 primarily related to obligations on behalf of NEP's subsidiaries with maturity dates ranging from 2019 to 2050 and included certain project performance obligations, obligations under financing and interconnection agreements and obligations related to the sale of differential membership interests. Payment guarantees and related contracts with respect to unconsolidated entities for which NEE or one of its subsidiaries are the guarantor are recorded on NEE’s condensed consolidated balance sheets at fair value. At March 31, 2019 , approximately $33 million related to the fair value of the credit support provided under the CSCS agreement is recorded as noncurrent other liabilities on NEE's condensed consolidated balance sheet. In March 2019, subsidiaries of NEER entered into an agreement to sell their ownership interests in certain wind and solar generation facilities to a NEP subsidiary.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments NEE and FPL use derivative instruments (primarily swaps, options, futures and forwards) to manage the physical and financial risks inherent in the purchase and sale of fuel and electricity, as well as interest rate and foreign currency exchange rate risk associated primarily with outstanding and expected future debt issuances and borrowings, and to optimize the value of NEER's power generation and gas infrastructure assets. NEE and FPL do not utilize hedge accounting for their cash flow and fair value hedges. With respect to commodities related to NEE's competitive energy business, NEER employs risk management procedures to conduct its activities related to optimizing the value of its power generation and gas infrastructure assets, providing full energy and capacity requirements services primarily to distribution utilities, and engaging in power and gas marketing and trading activities to take advantage of expected future favorable price movements and changes in the expected volatility of prices in the energy markets. These risk management activities involve the use of derivative instruments executed within prescribed limits to manage the risk associated with fluctuating commodity prices. Transactions in derivative instruments are executed on recognized exchanges or via the OTC markets, depending on the most favorable credit terms and market execution factors. For NEER's power generation and gas infrastructure assets, derivative instruments are used to hedge all or a portion of the expected output of these assets. These hedges are designed to reduce the effect of adverse changes in the wholesale forward commodity markets associated with NEER's power generation and gas infrastructure assets. With regard to full energy and capacity requirements services, NEER is required to vary the quantity of energy and related services based on the load demands of the customers served. For this type of transaction, derivative instruments are used to hedge the anticipated electricity quantities required to serve these customers and reduce the effect of unfavorable changes in the forward energy markets. Additionally, NEER takes positions in energy markets based on differences between actual forward market levels and management's view of fundamental market conditions, including supply/demand imbalances, changes in traditional flows of energy, changes in short- and long-term weather patterns and anticipated regulatory and legislative outcomes. NEER uses derivative instruments to realize value from these market dislocations, subject to strict risk management limits around market, operational and credit exposure. Derivative instruments, when required to be marked to market, are recorded on NEE's and FPL's condensed consolidated balance sheets as either an asset or liability measured at fair value. At FPL, substantially all changes in the derivatives' fair value are deferred as a regulatory asset or liability until the contracts are settled, and, upon settlement, any gains or losses are passed through the fuel clause. For NEE's non-rate regulated operations, predominantly NEER, essentially all changes in the derivatives' fair value for power purchases and sales, fuel sales and trading activities are recognized on a net basis in operating revenues and the equity method investees' related activity is recognized in equity in earnings of equity method investees in NEE's condensed consolidated statements of income. Settlement gains and losses are included within the line items in the condensed consolidated statements of income to which they relate. Transactions for which physical delivery is deemed not to have occurred are presented on a net basis in the condensed consolidated statements of income. For commodity derivatives, NEE believes that, where offsetting positions exist at the same location for the same time, the transactions are considered to have been netted and therefore physical delivery has been deemed not to have occurred for financial reporting purposes. Settlements related to derivative instruments are primarily recognized in net cash provided by operating activities in NEE's and FPL's condensed consolidated statements of cash flows. For interest rate and foreign currency derivative instruments, all changes in the derivatives' fair value, as well as the transaction gain or loss on foreign denominated debt, are recognized in interest expense and the equity method investees' related activity is recognized in equity in earnings of equity method investees in NEE's condensed consolidated statements of income. In addition, for the three months ended March 31, 2019 , NEE reclassified approximately $6 million ( $5 million after tax) from AOCI to interest expense primarily because it became probable that related future transactions being hedged would not occur. At March 31, 2019 , NEE's AOCI included amounts related to discontinued interest rate cash flow hedges with expiration dates through March 2035 and foreign currency cash flow hedges with expiration dates through September 2030 . Approximately $9 million of net losses included in AOCI at March 31, 2019 is expected to be reclassified into earnings within the next 12 months as the principal and/or interest payments are made. Such amounts assume no change in scheduled principal payments. Fair Value of Derivative Instruments - The tables below present NEE's and FPL's gross derivative positions at March 31, 2019 and December 31, 2018 , as required by disclosure rules. However, the majority of the underlying contracts are subject to master netting agreements and generally would not be contractually settled on a gross basis. Therefore, the tables below also present the derivative positions on a net basis, which reflect the offsetting of positions of certain transactions within the portfolio, the contractual ability to settle contracts under master netting arrangements and the netting of margin cash collateral (see Note 5 - Recurring Fair Value Measurements for netting information), as well as the location of the net derivative position on the condensed consolidated balance sheets.

(b) Reflects the netting of approximately $65 million in margin cash collateral received from counterparties. At March 31, 2019 and December 31, 2018 , NEE had approximately $13 million and $16 million (none at FPL), respectively, in margin cash collateral received from counterparties that was not offset against derivative assets in the above presentation. These amounts are included in current other liabilities on NEE's condensed consolidated balance sheets. Additionally, at March 31, 2019 and December 31, 2018 , NEE had approximately $263 million and $157 million (none at FPL), respectively, in margin cash collateral paid to counterparties that was not offset against derivative assets or liabilities in the above presentation. These amounts are included in current other assets on NEE's condensed consolidated balance sheets. Income Statement Impact of Derivative Instruments - Gains (losses) related to NEE's derivatives are recorded in NEE's condensed consolidated statements of income as follows: Three Months Ended March 31, 2019 2018 (millions) Commodity contracts (a) - operating revenues $ (4 ) $ 137 Foreign currency contracts - interest expense (19 ) 45 Interest rate contracts - interest expense (326 ) 59 Losses reclassified from AOCI to interest expense: Interest rate contracts (12 ) (9 ) Foreign currency contracts (1 ) (1 ) Total $ (362 ) $ 231 ——————————————— (a) For the three months ended March 31, 2019 and 2018, FPL recorded gains of approximately $2 million and $4 million , respectively, related to commodity contracts as regulatory liabilities on its condensed consolidated balance sheets. Notional Volumes of Derivative Instruments - The following table represents net notional volumes associated with derivative instruments that are required to be reported at fair value in NEE's and FPL's condensed consolidated financial statements. The table includes significant volumes of transactions that have minimal exposure to commodity price changes because they are variably priced agreements. These volumes are only an indication of the commodity exposure that is managed through the use of derivatives. They do not represent net physical asset positions or non-derivative positions and their hedges, nor do they represent NEE’s and FPL’s net economic exposure, but only the net notional derivative positions that fully or partially hedge the related asset positions. NEE and FPL had derivative commodity contracts for the following net notional volumes: March 31, 2019 December 31, 2018 Commodity Type NEE FPL NEE FPL (millions) Power (94 ) MWh 1 MWh (100 ) MWh 1 MWh Natural gas (1,114 ) MMBtu 334 MMBtu (491 ) MMBtu 231 MMBtu Oil (25 ) barrels — (30 ) barrels — At March 31, 2019 and December 31, 2018 , NEE had interest rate contracts with notional amounts totaling approximately $17.5 billion and $18.2 billion , respectively, and foreign currency contracts with notional amounts totaling approximately $656 million and $656 million , respectively. In April 2019, NEECH terminated a forward starting interest rate swap agreement with a notional amount of $5.2 billion . Credit - Risk - Related Contingent Features - Certain derivative instruments contain credit-risk-related contingent features including, among other things, the requirement to maintain an investment grade credit rating from specified credit rating agencies and certain financial ratios, as well as credit-related cross-default and material adverse change triggers. At March 31, 2019 and December 31, 2018 , the aggregate fair value of NEE's derivative instruments with credit-risk-related contingent features that were in a liability position was approximately $1.8 billion ( $20 million for FPL) and $1.8 billion ( $34 million for FPL), respectively. If the credit-risk-related contingent features underlying these derivative agreements were triggered, certain subsidiaries of NEE, including FPL, could be required to post collateral or settle contracts according to contractual terms which generally allow netting of contracts in offsetting positions. Certain derivative contracts contain multiple types of credit-related triggers. To the extent these contracts contain a credit ratings downgrade trigger, the maximum exposure is included in the following credit ratings collateral posting requirements. If FPL's and NEECH's credit ratings were downgraded to BBB/Baa2 (a two level downgrade for FPL and a one level downgrade for NEECH from the current lowest applicable rating), applicable NEE subsidiaries would be required to post collateral such that the total posted collateral would be approximately $110 million ( none at FPL ) at March 31, 2019 and $270 million ( none at FPL) at December 31, 2018 . If FPL's and NEECH's credit ratings were downgraded to below investment grade, applicable NEE subsidiaries would be required to post additional collateral such that the total posted collateral would be approximately $1.1 billion ( $30 million at FPL) at March 31, 2019 and $1.5 billion ( $45 million at FPL) at December 31, 2018 . Some derivative contracts do not contain credit ratings downgrade triggers, but do contain provisions that require certain financial measures be maintained and/or have credit-related cross-default triggers. In the event these provisions were triggered, applicable NEE subsidiaries could be required to post additional collateral of up to approximately $800 million ( $100 million at FPL) at March 31, 2019 and $610 million ( $145 million at FPL) at December 31, 2018 . Collateral related to derivatives may be posted in the form of cash or credit support in the normal course of business. At March 31, 2019 and December 31, 2018 , applicable NEE subsidiaries have posted approximately $2 million ( none at FPL) and $2 million ( none at FPL), respectively, in cash and $6 million ( none at FPL) and $88 million ( none at FPL), respectively, in the form of letters of credit, each of which could be applied toward the collateral requirements described above. FPL and NEECH have capacity under their credit facilities generally in excess of the collateral requirements described above that would be available to support, among other things, derivative activities. Under the terms of the credit facilities, maintenance of a specific credit rating is not a condition to drawing on these credit facilities, although there are other conditions to drawing on these credit facilities. Additionally, some contracts contain certain adequate assurance provisions whereby a counterparty may demand additional collateral based on subjective events and/or conditions. Due to the subjective nature of these provisions, NEE and FPL are unable to determine an exact value for these items and they are not included in any of the quantitative disclosures above.

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2019
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. NEE and FPL use 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. NEE's and FPL's assessment of the significance of any particular input to the fair value measurement requires judgment and may affect placement 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. Cash Equivalents and Restricted Cash Equivalents - NEE and FPL hold investments in money market funds. The fair value of these funds is estimated using a market approach based on current observable market prices. Special Use Funds and Other Investments - NEE and FPL hold primarily debt and equity securities directly, as well as indirectly through commingled funds. Substantially all directly held equity securities are valued at their quoted market prices. For directly held debt securities, multiple prices and price types are obtained from pricing vendors whenever possible, which enables cross-provider validations. A primary price source is identified based on asset type, class or issue of each security. Commingled funds, which are similar to mutual funds, are maintained by banks or investment companies and hold certain investments in accordance with a stated set of objectives. The fair value of commingled funds is primarily derived from the quoted prices in active markets of the underlying securities. Because the fund shares are offered to a limited group of investors, they are not considered to be traded in an active market. Derivative Instruments - NEE and FPL measure the fair value of commodity contracts using a combination of market and income approaches utilizing prices observed on commodities exchanges and in the OTC markets, or through the use of industry-standard valuation techniques, such as option modeling or discounted cash flows techniques, incorporating both observable and unobservable valuation inputs. The resulting measurements are the best estimate of fair value as represented by the transfer of the asset or liability through an orderly transaction in the marketplace at the measurement date. Most exchange-traded derivative assets and liabilities are valued directly using unadjusted quoted prices. For exchange-traded derivative assets and liabilities where the principal market is deemed to be inactive based on average daily volumes and open interest, the measurement is established using settlement prices from the exchanges, and therefore considered to be valued using other observable inputs. NEE, through its subsidiaries, including FPL, also enters into OTC commodity contract derivatives. The majority of these contracts are transacted at liquid trading points, and the prices for these contracts are verified using quoted prices in active markets from exchanges, brokers or pricing services for similar contracts. NEE, through NEER, also enters into full requirements contracts, which, in most cases, meet the definition of derivatives and are measured at fair value. These contracts typically have one or more inputs that are not observable and are significant to the valuation of the contract. In addition, certain exchange and non-exchange traded derivative options at NEE have one or more significant inputs that are not observable, and are valued using industry-standard option models. In all cases where NEE and FPL use significant unobservable inputs for the valuation of a commodity contract, consideration is given to the assumptions that market participants would use in valuing the asset or liability. The primary input to the valuation models for commodity contracts is the forward commodity curve for the respective instruments. Other inputs include, but are not limited to, assumptions about market liquidity, volatility, correlation and contract duration as more fully described below in Significant Unobservable Inputs Used in Recurring Fair Value Measurements. In instances where the reference markets are deemed to be inactive or do not have transactions for a similar contract, the derivative assets and liabilities may be valued using significant other observable inputs and potentially significant unobservable inputs. In such instances, the valuation for these contracts is established using techniques including extrapolation from or interpolation between actively traded contracts, or estimated basis adjustments from liquid trading points. NEE and FPL regularly evaluate and validate the inputs used to determine fair value by a number of methods, consisting of various market price verification procedures, including the use of pricing services and multiple broker quotes to support the market price of the various commodities. In all cases where there are assumptions and models used to generate inputs for valuing derivative assets and liabilities, the review and verification of the assumptions, models and changes to the models are undertaken by individuals that are independent of those responsible for estimating fair value. NEE uses interest rate contracts and foreign currency contracts to mitigate and adjust interest rate and foreign currency exchange exposure related primarily to certain outstanding and expected future debt issuances and borrowings when deemed appropriate based on market conditions or when required by financing agreements. NEE estimates the fair value of these 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.

(f) See Note 4 - Fair Value of Derivative Instruments for a reconciliation of net derivatives to NEE's and FPL's condensed consolidated balance sheets. Significant Unobservable Inputs Used in Recurring Fair Value Measurements - The valuation of certain commodity contracts requires the use of significant unobservable inputs. All forward price, implied volatility, implied correlation and interest rate inputs used in the valuation of such contracts are directly based on third-party market data, such as broker quotes and exchange settlements, when that data is available. If third-party market data is not available, then industry standard methodologies are used to develop inputs that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. Observable inputs, including some forward prices, implied volatilities and interest rates used for determining fair value are updated daily to reflect the best available market information. Unobservable inputs which are related to observable inputs, such as illiquid portions of forward price or volatility curves, are updated daily as well, using industry standard techniques such as interpolation and extrapolation, combining observable forward inputs supplemented by historical market and other relevant data. Other unobservable inputs, such as implied correlations, customer migration rates from full requirements contracts and some implied volatility curves, are modeled using proprietary models based on historical data and industry standard techniques. All price, volatility, correlation and customer migration inputs used in valuation are subject to validation by the Trading Risk Management group. The Trading Risk Management group performs a risk management function responsible for assessing credit, market and operational risk impact, reviewing valuation methodology and modeling, confirming transactions, monitoring approval processes and developing and monitoring trading limits. The Trading Risk Management group is separate from the transacting group. For markets where independent third-party data is readily available, validation is conducted daily by directly reviewing this market data against inputs utilized by the transacting group, and indirectly by reviewing daily risk reports. For markets where independent third-party data is not readily available, additional analytical reviews are performed on at least a quarterly basis. These analytical reviews are designed to ensure that all price and volatility curves used for fair valuing transactions are adequately validated each quarter, and are reviewed and approved by the Trading Risk Management group. In addition, other valuation assumptions such as implied correlations and customer migration rates are reviewed and approved by the Trading Risk Management group on a periodic basis. Newly created models used in the valuation process are also subject to testing and approval by the Trading Risk Management group prior to use and established models are reviewed annually, or more often as needed, by the Trading Risk Management group. On a monthly basis, the Exposure Management Committee (EMC), which is comprised of certain members of senior management, meets with representatives from the Trading Risk Management group and the transacting group to discuss NEE's and FPL's energy risk profile and operations, to review risk reports and to discuss fair value issues as necessary. The EMC develops guidelines required for an appropriate risk management control infrastructure, which includes implementation and monitoring of compliance with Trading Risk Management policy. The EMC executes its risk management responsibilities through direct oversight and delegation of its responsibilities to the Trading Risk Management group, as well as to other corporate and business unit personnel. The significant unobservable inputs used in the valuation of NEE's commodity contracts categorized as Level 3 of the fair value hierarchy at March 31, 2019 are as follows: Fair Value at Valuation Significant Transaction Type March 31, 2019 Technique(s) Unobservable Inputs Range Assets Liabilities (millions) Forward contracts - power $ 828 $ 180 Discounted cash flow Forward price (per MWh) $(17) — $167 Forward contracts - gas 81 22 Discounted cash flow Forward price (per MMBtu) $1 — $7 Forward contracts - other commodity related 4 3 Discounted cash flow Forward price (various) $1 — $64 Options - power 37 4 Option models Implied correlations 1% — 100% Implied volatilities 8% — 169% Options - primarily gas 105 111 Option models Implied correlations 1% — 100% Implied volatilities 1% — 135% Full requirements and unit contingent contracts 288 32 Discounted cash flow Forward price (per MWh) $(50) — $862 Customer migration rate (a) —% — 20% Total $ 1,343 $ 352 ——————————————— (a) Applies only to full requirements contracts. The sensitivity of NEE's fair value measurements to increases (decreases) in the significant unobservable inputs is as follows: Significant Unobservable Input Position Impact on Fair Value Measurement Forward price Purchase power/gas Increase (decrease) Sell power/gas Decrease (increase) Implied correlations Purchase option Decrease (increase) Sell option Increase (decrease) Implied volatilities Purchase option Increase (decrease) Sell option Decrease (increase) Customer migration rate Sell power (a) Decrease (increase) ——————————————— (a) Assumes the contract is in a gain position. In addition, the fair value measurement of interest rate contract net liabilities related to the solar projects in Spain of approximately $147 million at March 31, 2019 includes a significant credit valuation adjustment. The credit valuation adjustment, considered an unobservable input, reflects management's assessment of non-performance risk of the subsidiaries related to the solar projects in Spain that are party to the contracts. The reconciliation of changes in the fair value of derivatives that are based on significant unobservable inputs is as follows: Three Months Ended March 31, 2019 2018 NEE FPL NEE FPL (millions) Fair value of net derivatives based on significant unobservable inputs at December 31 of prior period $ 647 $ (36 ) $ 566 $ — Realized and unrealized gains (losses): Included in earnings (a) 180 — 16 — Included in other comprehensive income (loss) (b) 3 — (3 ) — Included in regulatory assets and liabilities (2 ) (2 ) (1 ) (2 ) Purchases 24 — 42 — Settlements (39 ) 20 48 — Issuances (14 ) — (33 ) — Impact of adoption of revenue standard — — (30 ) — Transfers out (c) 45 2 22 — Fair value of net derivatives based on significant unobservable inputs at March 31 $ 844 $ (16 ) $ 627 $ (2 ) Gains (losses) included in earnings attributable to the change in unrealized gains (losses) relating to derivatives held at the reporting date (d) $ 116 $ — $ 19 $ — ——————————————— (a) For the three months ended March 31, 2019 and 2018 , realized and unrealized gains of approximately $194 million and $26 million , respectively, are included in the condensed consolidated statements of income in operating revenues and the balance is included in interest expense. (b) Included in net unrealized gains (losses) on foreign currency translation in the condensed consolidated statements of comprehensive income. (c) Transfers from Level 3 to Level 2 were a result of increased observability of market data. NEE's and FPL's policy is to recognize all transfers at the beginning of the reporting period. (d) For the three months ended March 31, 2019 and 2018 , unrealized gains of approximately $130 million and $29 million , respectively, are included in the condensed consolidated statements of income in operating revenues and the balance is included in interest expense. Fair Value of Financial Instruments Recorded at Other than Fair Value - The carrying amounts of commercial paper and other short-term debt approximate their fair values. The carrying amounts and estimated fair values of other financial instruments recorded at other than fair value are as follows: March 31, 2019 December 31, 2018 Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value (millions) NEE: Special use funds (a) $ 930 $ 929 $ 884 $ 883 Other investments (b) $ 39 $ 39 $ 54 $ 54 Long-term debt, including current portion $ 32,497 (c) $ 34,165 (c)(d) $ 29,498 $ 30,043 (d) FPL: Special use funds (a) $ 759 $ 758 $ 693 $ 692 Long-term debt, including current portion $ 12,379 $ 13,756 (d) $ 11,783 $ 12,613 (d) ——————————————— (a) Primarily represents investments accounted for under the equity method and loans not measured at fair value on a recurring basis (Level 2).

(c) Excludes debt totaling approximately $876 million reflected in liabilities associated with assets held for sale on NEE's condensed consolidated balance sheets for which the carrying amount approximates fair value. See Note 11 - Assets and Liabilities Associated with Assets Held for Sale. (d) At March 31, 2019 and December 31, 2018 , substantially all is Level 2 for NEE and all is Level 2 for FPL. Special Use Funds - The special use funds noted above and those carried at fair value (see Recurring Fair Value Measurements above) consist of NEE's nuclear decommissioning fund assets of approximately $6,291 million and $5,818 million at March 31, 2019 and December 31, 2018 , respectively, ( $4,298 million and $3,987 million , respectively, for FPL) and FPL's storm fund assets of $69 million and $68 million at March 31, 2019 and December 31, 2018 , respectively. The investments held in the special use funds consist of equity securities and available for sale debt securities which are primarily carried at estimated fair value. The amortized cost of debt securities is approximately $1,980 million and $1,994 million at March 31, 2019 and December 31, 2018 , respectively, ( $1,485 million and $1,542 million , respectively, for FPL). For FPL's special use funds, consistent with regulatory treatment, changes in fair value, including any other than temporary impairment losses, result in a corresponding adjustment to the related regulatory asset or liability accounts. For NEE's non-rate regulated operations, changes in fair value of debt securities result in a corresponding adjustment to OCI, except for unrealized losses considered to be other than temporary, including any credit losses, which are recognized in other - net in NEE's condensed consolidated statements of income. For NEE's non-rate regulated operations, changes in fair value of equity securities are recorded in change in unrealized gains (losses) on equity securities held in NEER's nuclear decommissioning funds - net in NEE’s condensed consolidated statements of income. The unrealized gains (losses) recognized during the three months ended March 31, 2019 and 2018 on equity securities held at March 31, 2019 and March 31, 2018 were $367 million and $(20) million , respectively ( $234 million for the three months ended March 31, 2019 for FPL). Debt securities included in the nuclear decommissioning funds have a weighted-average maturity at March 31, 2019 of approximately eight years at both NEE and FPL. FPL's storm fund primarily consists of debt securities with a weighted-average maturity at March 31, 2019 of approximately one year. The cost of securities sold is determined using the specific identification method. Realized gains and losses and proceeds from the sale or maturity of available for sale securities are as follows: NEE FPL Three Months Ended March 31, Three Months Ended March 31, 2019 2018 2019 2018 (millions) Realized gains $ 9 $ 8 $ 5 $ 5 Realized losses $ 9 $ 14 $ 4 $ 9 Proceeds from sale or maturity of securities $ 687 $ 595 $ 543 $ 389 The unrealized gains and unrealized losses on available for sale debt securities and the fair value of available for sale debt securities in an unrealized loss position are as follows: NEE FPL March 31, 2019 December 31, 2018 March 31, 2019 December 31, 2018 (millions) Unrealized gains $ 37 $ 14 $ 28 $ 11 Unrealized losses (a) $ 18 $ 52 $ 14 $ 41 Fair value $ 676 $ 1,273 $ 508 $ 961 ——————————————— (a) Unrealized losses on available for sale debt securities in an unrealized loss position for greater than twelve months at March 31, 2019 and December 31, 2018 were not material to NEE or FPL. Regulations issued by the FERC and the NRC provide general risk management guidelines to protect nuclear decommissioning funds and to allow such funds to earn a reasonable return. The FERC regulations prohibit, among other investments, investments in any securities of NEE or its subsidiaries, affiliates or associates, excluding investments tied to market indices or mutual funds. Similar restrictions applicable to the decommissioning funds for NEER's nuclear plants are included in the NRC operating licenses for those facilities or in NRC regulations applicable to NRC licensees not in cost-of-service environments. With respect to the decommissioning fund for Seabrook, decommissioning fund contributions and withdrawals are also regulated by the New Hampshire Nuclear Decommissioning Financing Committee pursuant to New Hampshire law. The nuclear decommissioning reserve funds are managed by investment managers who must comply with the guidelines of NEE and FPL and the rules of the applicable regulatory authorities. The funds' assets are invested giving consideration to taxes, liquidity, risk, diversification and other prudent investment objectives.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes NEE's effective income tax rates for the three months ended March 31, 2019 and 2018 were approximately 11% and 25% , respectively. The rates for both periods reflect state income taxes net of federal income tax benefits, the benefits of PTCs of approximately $14 million and $23 million , respectively, related to NEER's wind projects and ITCs of approximately $40 million and $36 million , respectively, related to solar and certain wind projects at NEER. During the three months ended March 31, 2019 and 2018 , NEE recorded income tax benefits of $33 million and $29 million related to the amortization of deferred regulatory credits, primarily at FPL. During the three months ended March 31, 2018, NEE recorded an income tax charge of approximately $ 125 million related to an adjustment to differential membership interests primarily as a result of the change in federal income tax rates effective January 1, 2018. NEE recognizes PTCs as wind energy is generated and sold based on a per kWh rate prescribed in applicable federal and state statutes, which may differ significantly from amounts computed, on a quarterly basis, using an overall effective income tax rate anticipated for the full year. NEE uses this method of recognizing PTCs for specific reasons, including that PTCs are an integral part of the financial viability of most wind projects and a fundamental component of such wind projects' results of operations. PTCs, as well as ITCs, can significantly affect NEE's effective income tax rate depending on the amount of pretax income. The amount of PTCs recognized can be significantly affected by wind generation and by the roll off of PTCs after ten years of production.

Acquisitions

Acquisitions	3 Months Ended

Business Combinations [Abstract]
Acquisitions	Acquisitions Gulf Power - On January 1, 2019, NEE acquired the outstanding common shares of Gulf Power, a rate-regulated electric utility under the jurisdiction of the FPSC. Gulf Power serves more than 460,000 customers in eight counties throughout northwest Florida, has approximately 9,400 miles of transmission and distribution lines and owns approximately 2,300 MW of net generating capacity. The purchase price included approximately $4.47 billion in cash consideration less estimated post-closing working capital adjustments of $104 million and the assumption of approximately $1.3 billion of Gulf Power debt. The cash purchase price was funded through $4.5 billion of borrowings by NEECH in December 2018 under certain short-term bi-lateral term loan agreements (see Note 10); the proceeds of which borrowings were restricted and included in noncurrent other assets on NEE's condensed consolidated balance sheet at December 31, 2018. Under the acquisition method, the purchase price was allocated to the assets acquired and liabilities assumed on January 1, 2019 based on their fair value. The approval by the FPSC of Gulf Power's rates, which is intended to allow Gulf Power to collect from retail customers total revenues equal to Gulf Power's costs of providing service, including a reasonable rate of return on invested capital, is considered a fundamental input in measuring the fair value of Gulf Power's assets and liabilities and, as such, NEE concluded that the carrying values of all assets and liabilities recoverable through rates are representative of their fair values. As a result, NEE acquired assets of approximately $5.3 billion , primarily relating to property, plant and equipment of $4.0 billion and regulatory assets of $490 million , and assumed liabilities of approximately $3.5 billion , including $1.3 billion of long-term debt, $640 million of regulatory liabilities and $590 million of deferred income taxes. The excess of the purchase price over the fair value of assets acquired and liabilities assumed resulted in approximately $2.6 billion of goodwill which has been recognized on NEE's condensed consolidated balance sheet at March 31, 2019 . Goodwill associated with the Gulf Power acquisition will be reflected within Corporate and Other and, for impairment testing, will be included in the Gulf Power reporting unit. The goodwill arising from the transaction represents expected benefits from continued expansion of NEE's regulated business mix and the indefinite life of Gulf Power's service territory franchise. In connection with the acquisition, operating right-of-use assets and lease liabilities were recorded primarily related to a purchased power agreement; such amounts each totaled approximately $248 million at March 31, 2019 . The operating leases have fixed payments with expiration dates ranging from late 2019 to 2023. At March 31, 2019 , expected lease payments over the remaining terms of the operating leases were approximately $260 million with no one year being material. Gulf Power's operating leases did not have a material impact to NEE's condensed consolidated statements of income or cash flows. Trans Bay Cable, LLC - In March 2019, a wholly owned subsidiary of NextEra Energy Transmission, LLC received FERC approval to acquire the outstanding membership interests of Trans Bay Cable, LLC for approximately $1.05 billion , including the assumption of debt. The acquisition is expected to close in 2019, pending approval of the California Public Utilities Commission.

Variable Interest Entities (VIE

Variable Interest Entities (VIEs)	3 Months Ended
	Mar. 31, 2019
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.

Accounting Policies [Abstract]
Summary of Significant Accounting and Reporting Policies	Summary of Significant Accounting and Reporting Policies Restricted Cash - At March 31, 2019 and December 31, 2018 , NEE had approximately $369 million ( $122 million for FPL) and $4,615 million ( $142 million for FPL), respectively, of restricted cash, of which approximately $307 million ( $61 million for FPL) and $89 million ( $81 million for FPL), respectively, is included in current other assets and the remaining balance is included in noncurrent other assets on NEE's and FPL's condensed consolidated balance sheets. Restricted cash is primarily related to debt service payments, bond proceeds held for construction at FPL and margin cash collateral requirements, and, at December 31, 2018, also related to cash restricted for the acquisition of Gulf Power (see Note 7 - Gulf Power). In addition, where offsetting positions exist, restricted cash related to margin cash collateral is netted against derivative instruments, which totaled $57 million and $184 million at March 31, 2019 and December 31, 2018 , respectively. See Note 4. Assets and Liabilities Associated with Assets Held for Sale - In March 2019, subsidiaries of NEER entered into an agreement to sell their ownership interests in three wind generation facilities and three solar generation facilities located in the Midwest and West regions of the U.S. with a total net generating capacity of 611 MW to a NEP subsidiary for a cash purchase price of approximately $1,020 million , subject to certain adjustments. A NEER affiliate will continue to operate the facilities included in the sale. The transaction is expected to close in the second quarter of 2019, pending the receipt of necessary regulatory approvals and satisfaction of other customary closing conditions. 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, 2019 primarily represent property, plant and equipment and the related long-term debt.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments - NEE and its subsidiaries have made commitments in connection with a portion of their projected capital expenditures. Capital expenditures at FPL and Gulf Power include, among other things, the cost for construction of additional facilities and equipment to meet customer demand, as well as capital improvements to and maintenance of existing facilities. At NEER, capital expenditures include, among other things, the cost, including capitalized interest, for construction and development of wind and solar projects and the procurement of nuclear fuel, as well as equity contributions to joint ventures for the development and construction of natural gas pipeline assets. Capital expenditures for Corporate and Other primarily include the cost to maintain existing transmission facilities at NEET. At March 31, 2019 , estimated capital expenditures for the remainder of 2019 through 2023 for which applicable internal approvals (and also, if required, regulatory approvals such as FPSC approvals for FPL and Gulf Power) have been received were as follows: Remainder of 2019 2020 2021 2022 2023 Total (millions) FPL: Generation: (a) New (b) $ 1,075 $ 1,410 $ 995 $ 1,000 $ 790 $ 5,270 Existing 985 700 895 760 810 4,150 Transmission and distribution (c) 2,205 3,170 3,135 3,530 3,895 15,935 Nuclear fuel 125 205 220 165 120 835 General and other 545 535 425 345 365 2,215 Total $ 4,935 $ 6,020 $ 5,670 $ 5,800 $ 5,980 $ 28,405 Gulf Power $ 605 $ 915 $ 740 $ 465 $ 270 $ 2,995 NEER: Wind (d) $ 1,580 $ 2,960 $ 130 $ 20 $ 20 $ 4,710 Solar (e) 570 230 160 — 5 965 Nuclear, including nuclear fuel 150 160 165 180 130 785 Natural gas pipelines (f) 570 310 15 20 — 915 Other 490 50 40 40 40 660 Total $ 3,360 $ 3,710 $ 510 $ 260 $ 195 $ 8,035 Corporate and Other $ 60 $ 30 $ 15 $ — $ — $ 105 ——————————————— (a) Includes AFUDC of approximately $40 million , $70 million , $85 million , $60 million and $35 million for the remainder of 2019 through 2023, respectively.

(c) Includes AFUDC of approximately $15 million , $45 million , $45 million , $55 million and $45 million for the remainder of 2019 through 2023, respectively. (d) Consists of capital expenditures for new wind projects, repowering of existing wind projects and related transmission totaling approximately 5,740 MW. (e) Includes capital expenditures for new solar projects and related transmission totaling approximately 930 MW. (f) Construction of a natural gas pipeline is subject to certain conditions, including FERC approval. In addition, completion of another natural gas pipeline is subject to final permitting. The above estimates are subject to continuing review and adjustment and actual capital expenditures may vary significantly from these estimates. Contracts - In addition to the commitments made in connection with the estimated capital expenditures included in the table in Commitments above, FPL has firm commitments under long-term contracts primarily for the transportation of natural gas and coal with expiration dates through 2042 . At March 31, 2019 , NEER has entered into contracts with expiration dates ranging from June 2019 through 2032 primarily for the purchase of wind turbines, wind towers and solar modules and related construction and development activities, as well as for the supply of uranium, and the conversion, enrichment and fabrication of nuclear fuel, and has made commitments for the construction of natural gas pipelines. Approximately $3.5 billion of related commitments are included in the estimated capital expenditures table in Commitments above. In addition, NEER has contracts primarily for the transportation and storage of natural gas with expiration dates ranging from late April 2019 through 2050 . The required capacity and/or minimum payments under contracts, including those discussed above, at March 31, 2019 were estimated as follows: Remainder of 2019 2020 2021 2022 2023 Thereafter (millions) FPL (a) $ 750 $ 995 $ 985 $ 975 $ 970 $ 11,500 NEER (b)(c) $ 2,315 $ 1,075 $ 175 $ 185 $ 110 $ 1,380 Corporate and Other (d) $ 40 $ 5 $ 5 $ — $ — $ — ——————————————— (a) Includes approximately $240 million , $385 million , $415 million , $415 million , $410 million and $7,175 million for the remainder of 2019 through 2023 and thereafter, respectively, of firm commitments related to the natural gas transportation agreements with Sabal Trail and Florida Southeast Connection. The charges associated with these agreements are recoverable through the fuel clause and totaled approximately $79 million and $73 million for the three months ended March 31, 2019 and 2018, respectively, of which $28 million and $22 million , respectively, were eliminated in consolidation at NEE. (b) Includes approximately $50 million , $65 million , $65 million , $65 million and $1,050 million for 2020 through 2023 and thereafter, respectively, of firm commitments related to a natural gas transportation agreement with a joint venture, in which NEER has a 31% equity investment, that is constructing a natural gas pipeline. These firm commitments are subject to the completion of construction of the pipeline. (c) Includes an approximately $55 million commitment to invest in clean power and technology businesses through 2022. (d) Excludes approximately $25 million , $20 million , $10 million , $10 million and $5 million for the remainder of 2019 through 2023, respectively, of joint obligations of NEECH and NEER which are included in the NEER amounts above. Insurance - Liability for accidents at nuclear power plants is governed by the Price-Anderson Act, which limits the liability of nuclear reactor owners to the amount of insurance available from both private sources and an industry retrospective payment plan. In accordance with this Act, NEE maintains $450 million of private liability insurance per site, which is the maximum obtainable, and participates in a secondary financial protection system, which provides up to $13.6 billion of liability insurance coverage per incident at any nuclear reactor in the U.S. Under the secondary financial protection system, NEE is subject to retrospective assessments of up to $1.1 billion ( $550 million for FPL), plus any applicable taxes, per incident at any nuclear reactor in the U.S., payable at a rate not to exceed $164 million ( $82 million for FPL) per incident per year. NEE and FPL are contractually entitled to recover a proportionate share of such assessments from the owners of minority interests in Seabrook, Duane Arnold and St. Lucie Unit No. 2, which approximates $16 million , $41 million and $20 million , plus any applicable taxes, per incident, respectively. NEE participates in a nuclear insurance mutual company that provides $2.75 billion of limited insurance coverage per occurrence per site for property damage, decontamination and premature decommissioning risks at its nuclear plants and a sublimit of $1.5 billion for non-nuclear perils, except for Duane Arnold which has a sublimit of $500 million . NEE participates in co-insurance of 10% of the first $400 million of losses per site per occurrence. The proceeds from such insurance, however, must first be used for reactor stabilization and site decontamination before they can be used for plant repair. NEE also participates in an insurance program that provides limited coverage for replacement power costs if a nuclear plant is out of service for an extended period of time because of an accident. In the event of an accident at one of NEE's or another participating insured's nuclear plants, NEE could be assessed up to $174 million ( $106 million for FPL), plus any applicable taxes, in retrospective premiums in a policy year. NEE and FPL are contractually entitled to recover a proportionate share of such assessments from the owners of minority interests in Seabrook, Duane Arnold and St. Lucie Unit No. 2, which approximates $3 million , $4 million and $4 million , plus any applicable taxes, respectively. Due to the high cost and limited coverage available from third-party insurers, NEE does not have property insurance coverage for a substantial portion of either its transmission and distribution property or natural gas pipeline assets. If either FPL's or Gulf Power's future storm restoration costs exceed their respective storm reserve, FPL and Gulf Power may recover their storm restoration costs, subject to prudence review by the FPSC, either through surcharges approved by the FPSC or through securitization provisions pursuant to Florida law. In the event of a loss, the amount of insurance available might not be adequate to cover property damage and other expenses incurred. Uninsured losses and other expenses, to the extent not recovered from customers in the case of FPL or Gulf Power, would be borne by NEE and either FPL or Gulf Power, and could have a material adverse effect on NEE's and FPL's financial condition, results of operations and liquidity.

Summary of Significant Accoun_2

Summary of Significant Accounting and Reporting Policies (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Derivative Instruments	NEE and FPL use derivative instruments (primarily swaps, options, futures and forwards) to manage the physical and financial risks inherent in the purchase and sale of fuel and electricity, as well as interest rate and foreign currency exchange rate risk associated primarily with outstanding and expected future debt issuances and borrowings, and to optimize the value of NEER's power generation and gas infrastructure assets. NEE and FPL do not utilize hedge accounting for their cash flow and fair value hedges. With respect to commodities related to NEE's competitive energy business, NEER employs risk management procedures to conduct its activities related to optimizing the value of its power generation and gas infrastructure assets, providing full energy and capacity requirements services primarily to distribution utilities, and engaging in power and gas marketing and trading activities to take advantage of expected future favorable price movements and changes in the expected volatility of prices in the energy markets. These risk management activities involve the use of derivative instruments executed within prescribed limits to manage the risk associated with fluctuating commodity prices. Transactions in derivative instruments are executed on recognized exchanges or via the OTC markets, depending on the most favorable credit terms and market execution factors. For NEER's power generation and gas infrastructure assets, derivative instruments are used to hedge all or a portion of the expected output of these assets. These hedges are designed to reduce the effect of adverse changes in the wholesale forward commodity markets associated with NEER's power generation and gas infrastructure assets. With regard to full energy and capacity requirements services, NEER is required to vary the quantity of energy and related services based on the load demands of the customers served. For this type of transaction, derivative instruments are used to hedge the anticipated electricity quantities required to serve these customers and reduce the effect of unfavorable changes in the forward energy markets. Additionally, NEER takes positions in energy markets based on differences between actual forward market levels and management's view of fundamental market conditions, including supply/demand imbalances, changes in traditional flows of energy, changes in short- and long-term weather patterns and anticipated regulatory and legislative outcomes. NEER uses derivative instruments to realize value from these market dislocations, subject to strict risk management limits around market, operational and credit exposure. Derivative instruments, when required to be marked to market, are recorded on NEE's and FPL's condensed consolidated balance sheets as either an asset or liability measured at fair value. At FPL, substantially all changes in the derivatives' fair value are deferred as a regulatory asset or liability until the contracts are settled, and, upon settlement, any gains or losses are passed through the fuel clause. For NEE's non-rate regulated operations, predominantly NEER, essentially all changes in the derivatives' fair value for power purchases and sales, fuel sales and trading activities are recognized on a net basis in operating revenues and the equity method investees' related activity is recognized in equity in earnings of equity method investees in NEE's condensed consolidated statements of income. Settlement gains and losses are included within the line items in the condensed consolidated statements of income to which they relate. Transactions for which physical delivery is deemed not to have occurred are presented on a net basis in the condensed consolidated statements of income. For commodity derivatives, NEE believes that, where offsetting positions exist at the same location for the same time, the transactions are considered to have been netted and therefore physical delivery has been deemed not to have occurred for financial reporting purposes. Settlements related to derivative instruments are primarily recognized in net cash provided by operating activities in NEE's and FPL's condensed consolidated statements of cash flows. For interest rate and foreign currency derivative instruments, all changes in the derivatives' fair value, as well as the transaction gain or loss on foreign denominated debt, are recognized in interest expense and the equity method investees' related activity is recognized in equity in earnings of equity method investees in NEE's condensed consolidated statements of income.
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. NEE and FPL use 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. NEE's and FPL's assessment of the significance of any particular input to the fair value measurement requires judgment and may affect placement 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. Cash Equivalents and Restricted Cash Equivalents - NEE and FPL hold investments in money market funds. The fair value of these funds is estimated using a market approach based on current observable market prices. Special Use Funds and Other Investments - NEE and FPL hold primarily debt and equity securities directly, as well as indirectly through commingled funds. Substantially all directly held equity securities are valued at their quoted market prices. For directly held debt securities, multiple prices and price types are obtained from pricing vendors whenever possible, which enables cross-provider validations. A primary price source is identified based on asset type, class or issue of each security. Commingled funds, which are similar to mutual funds, are maintained by banks or investment companies and hold certain investments in accordance with a stated set of objectives. The fair value of commingled funds is primarily derived from the quoted prices in active markets of the underlying securities. Because the fund shares are offered to a limited group of investors, they are not considered to be traded in an active market. Derivative Instruments - NEE and FPL measure the fair value of commodity contracts using a combination of market and income approaches utilizing prices observed on commodities exchanges and in the OTC markets, or through the use of industry-standard valuation techniques, such as option modeling or discounted cash flows techniques, incorporating both observable and unobservable valuation inputs. The resulting measurements are the best estimate of fair value as represented by the transfer of the asset or liability through an orderly transaction in the marketplace at the measurement date. Most exchange-traded derivative assets and liabilities are valued directly using unadjusted quoted prices. For exchange-traded derivative assets and liabilities where the principal market is deemed to be inactive based on average daily volumes and open interest, the measurement is established using settlement prices from the exchanges, and therefore considered to be valued using other observable inputs. NEE, through its subsidiaries, including FPL, also enters into OTC commodity contract derivatives. The majority of these contracts are transacted at liquid trading points, and the prices for these contracts are verified using quoted prices in active markets from exchanges, brokers or pricing services for similar contracts. NEE, through NEER, also enters into full requirements contracts, which, in most cases, meet the definition of derivatives and are measured at fair value. These contracts typically have one or more inputs that are not observable and are significant to the valuation of the contract. In addition, certain exchange and non-exchange traded derivative options at NEE have one or more significant inputs that are not observable, and are valued using industry-standard option models. In all cases where NEE and FPL use significant unobservable inputs for the valuation of a commodity contract, consideration is given to the assumptions that market participants would use in valuing the asset or liability. The primary input to the valuation models for commodity contracts is the forward commodity curve for the respective instruments. Other inputs include, but are not limited to, assumptions about market liquidity, volatility, correlation and contract duration as more fully described below in Significant Unobservable Inputs Used in Recurring Fair Value Measurements. In instances where the reference markets are deemed to be inactive or do not have transactions for a similar contract, the derivative assets and liabilities may be valued using significant other observable inputs and potentially significant unobservable inputs. In such instances, the valuation for these contracts is established using techniques including extrapolation from or interpolation between actively traded contracts, or estimated basis adjustments from liquid trading points. NEE and FPL regularly evaluate and validate the inputs used to determine fair value by a number of methods, consisting of various market price verification procedures, including the use of pricing services and multiple broker quotes to support the market price of the various commodities. In all cases where there are assumptions and models used to generate inputs for valuing derivative assets and liabilities, the review and verification of the assumptions, models and changes to the models are undertaken by individuals that are independent of those responsible for estimating fair value. NEE uses interest rate contracts and foreign currency contracts to mitigate and adjust interest rate and foreign currency exchange exposure related primarily to certain outstanding and expected future debt issuances and borrowings when deemed appropriate based on market conditions or when required by financing agreements. NEE estimates the fair value of these 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.
