grid technology to manage the electric system in order to maintain reliable service. In 2016, the company had about of power lines in Florida. In January 2021 Gulf Power Company was legally merged into FPL, extending FPL's service territory into Northwest Florida. Gulf Power will operate as a separate division within FPL through 2021. The two companies will be regulated as separate entities until the Florida Public Service Commission approves the consolidation of their tariffs. In consequence, FPL would also assume Gulf Power's share of the Scherer plant, as well as its share of the Daniel Generating Plant in Jackson County, Mississippi, which Gulf Power co-owned with its former sister company, Mississippi Power.

NextEra Energy and its other subsidiaries, particularly NextEra Energy Resources, have significantly different generation profiles. FPL Cape Canaveral Next Generation Energy Center An 800 MW dual fuel facility was built near Cape Canaveral in 1965 to supply power to the new Kennedy Space Center.

The FPL Cape Canaveral Next Generation Energy Center in Sharpes, Florida was completed and opened in April 2013. The 1,200 MW combined-cycle natural gas-fired facility was 33 percent more efficient than the plant it replaced and produced half the carbon dioxide emissions, 90 percent less pollutants, and had a 50 percent greater capacity. The plant cost $900 million to complete, which was about $140 million under the projected budget.
