Business Combinations [Abstract]
Acquisitions	Acquisitions Merger of FPL and Gulf Power Company - On January 1, 2021, FPL and Gulf Power Company merged, with FPL as the surviving entity. However, FPL will continue to be regulated as two separate ratemaking entities until the FPSC approves consolidation of the FPL segment and Gulf Power rates and tariffs. The FPL segment and Gulf Power will continue to be separate operating segments of NEE as well as FPL through 2021. See Note 13. As a result of the merger, FPL acquired assets of approximately $6.7 billion, primarily relating to property, plant and equipment of approximately $4.9 billion and regulatory assets of $1.2 billion, and assumed liabilities of approximately $3.9 billion, including $1.8 billion of debt, primarily long-term debt, $729 million of deferred income taxes and $566 million of regulatory liabilities. Additionally, goodwill of approximately $2.7 billion and purchase accounting adjustments associated with the 2019 Gulf Power Company acquisition by NEE were transferred to FPL from NEE Corporate and Other. The assets acquired and liabilities assumed by FPL were at carrying amounts as the merger was between entities under common control. GridLiance - On March 31, 2021, a wholly owned subsidiary of NEET acquired GridLiance Holdco, LP and GridLiance GP, LLC (GridLiance), which owns and operates three FERC-regulated transmission utilities with approximately 700 miles of high-voltage transmission lines across six states, five in the Midwest and Nevada. The purchase price included approximately $502 million in cash consideration, and the assumption of approximately $175 million of debt, excluding post-closing adjustments. Under the acquisition method, the purchase price was allocated to the assets acquired and liabilities assumed based on their fair value. The approval by the FERC of GridLiance’s rates, which is intended to allow GridLiance to collect total revenues equal to GridLiance's costs for the development, financing, construction, operation and maintenance of GridLiance, including a reasonable rate of return on invested capital, is considered a fundamental input in measuring the fair value of GridLiance'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 $389 million, primarily relating to property, plant and equipment, and assumed liabilities of approximately $222 million, primarily relating to long-term debt. The acquisition agreements are subject to earn-out provisions for additional payments, valued at approximately $264 million at March 31, 2021, to be made upon the completion of capital expenditures for future development projects (see Note 3 - Contingent Consideration). The excess of the purchase price over the fair value of assets acquired and liabilities assumed resulted in approximately $599 million of goodwill which has been recognized on NEE's condensed consolidated balance sheet at March 31, 2021, of which approximately $597 million is expected to be deductible for tax purposes. Goodwill associated with the GridLiance acquisition is reflected within NEER and, for impairment testing, is included in the rate-regulated transmission reporting unit. The goodwill arising from the transaction represents expected benefits from continued expansion of NEE's regulated businesses. The valuation of the acquired net assets is subject to change as additional information related to the estimates is obtained during the measurement period.
