Acquisitions	Acquisitions Gulf Power Company - On January 1, 2019, NEE acquired the outstanding common shares of Gulf Power Company (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 and has approximately 9,400 miles of transmission and distribution lines and 2,300 MW of electric generating capacity. The aggregate purchase price included approximately $4.47 billion in cash consideration, excluding post-closing working capital adjustments, 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 which mature in June 2019; the proceeds of which borrowings were restricted and included in noncurrent other assets on NEE's consolidated balance sheet at December 31, 2018. NEE incurred approximately $26 million in acquisition-related costs during the year ended December 31, 2018, which are reflected in merger-related expenses in NEE's consolidated statements of income. NEE is in the process of evaluating the purchase accounting considerations, including the initial purchase price allocation.

Upon closing, NEE transferred FCG to FPL. In December 2018, NEE acquired a 100% interest in an entity that indirectly owns Oleander Power Project, an approximately 791 MW natural gas-fired, simple-cycle combustion turbine electric generation facility located near Cocoa, Florida, and a 100% interest in an entity that owns a 65% interest in Stanton Energy Center Unit A, an approximately 660 MW combined-cycle electric generation facility located near Orlando, Florida for approximately $200 million in cash, subject to certain adjustments. Trans Bay Cable, LLC - In November 2018, a wholly owned subsidiary of NextEra Energy Transmission, LLC (NEET) entered into an agreement to acquire the outstanding membership interests of Trans Bay Cable, LLC (Trans Bay) for approximately $1.05 billion, including the assumption of debt, pending, among other things, approval of the California Public Utilities Commission and the FERC.
