Turkey Point Nuclear Generating Station is a nuclear and gas-fired power plant located on a site two miles east of Homestead, Florida, United States, next to Biscayne National Park located about south of Miami, Florida near the southernmost edge of Miami-Dade County. The facility is owned by Florida Power & Light. Including the two nuclear plants, Turkey Point operates three power-generating units. It comprises two retired 404 megawatt fuel oil/natural gas/used oil/propane-fired generation units (Units 1 and 2), two 802 MWe Westinghouse pressurized water reactors (Units 3 and 4), and a 1,150 MW combined-cycle gas-fired Unit 5. It serves the entire southern portion of Florida. With a combined operational capacity of 2754 MW, the site is the third largest generating station in Florida and the eleventh largest power plant in the United States. The US Nuclear Regulatory Commission has authorized its staff to issue combined licences for Florida Power and Light to build and operate two Westinghouse AP1000 reactors at its Turkey Point site. Construction The two pressurized water reactors were completed in 1972 and 1973. Expansion In 2002, the Nuclear Regulatory Commission (NRC) extended the operating licenses for both nuclear reactors from forty years to sixty years. In 2006, Florida Power & Light (FPL) informed the NRC that they planned to apply for new units to be built at Turkey Point. FPL filed an initial proposal for increased capacity with the Florida Public Service Commission in October 2007. The proposal was approved by the PSC in March 2008. FPL also planned to spend about $1.5 billion to increase the capacity of its existing four reactors at Turkey Point and the St. Lucie Nuclear Power Plant by a total of about 400 MW by 2012. On June 30, 2009, FPL submitted a Combined Construction and Operating License (COL) application for two 1,117-MWe Westinghouse AP1000 reactors (Units 6 and 7). FPL had considered building two 1,550-MWe GE ESBWR reactors. Construction was expected to begin in 2012, with the new units going online in 2017 and 2019. FPL estimated the total overnight costs of the power plants, including first fuel load, at $6.8–$9.9 billion, and the total project cost at $12.1–$17.8 billion. The COLs for units 6 and 7 were authorized by the NRC in April 2018. Criticism of expansion The expansion received criticism from some South Florida mayors over concerns about water usage, insufficient evacuation zones and increased risks from rising
