Accounting Policies [Abstract] |
Summary of Significant Accounting and Reporting Policies | Summary of Significant Accounting and Reporting Policies Rate Regulation - In June 2019, the FPSC issued a final order in connection with its review of impacts associated with tax reform, which allows FPL to continue to operate under the 2016 rate agreement. The order confirms that FPL's actions to use available reserve amortization to offset nearly all of the expense associated with the write-off of the regulatory asset related to Hurricane Irma cost recovery were permitted under the terms of the 2016 rate agreement, that FPL is able to credit the reserve with tax savings resulting from tax reform and that FPL's rates remain just and reasonable. In July 2019, the State of Florida Office of Public Counsel filed a notice of appeal challenging the FPSC's order, which notice of appeal is pending before the Florida Supreme Court. Restricted Cash - At June 30, 2019 and December 31, 2018, NEE had approximately $684 million ($167 million for FPL) and $4,615 million ($142 million for FPL), respectively, of restricted cash, of which approximately $595 million ($77 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 of $220 million is netted against derivative liabilities at June 30, 2019 and $184 million is netted against derivative assets at December 31, 2018. See Note 4. Disposal of Businesses - In June 2019, subsidiaries of NEER completed the sale of 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 cash proceeds of approximately $1,020 million, plus working capital of $12 million (subject to post-closing working capital and other adjustments). A NEER affiliate will continue to operate the facilities included in the sale. In connection with the sale, a gain of approximately $351 million ($266 million after tax) was recorded in NEE's condensed consolidated statements of income for the three and six months ended June 30, 2019 and is included in gains on disposal of businesses/assets - net.
