NEW YORK, June 1 FPL Group Inc's (FPL.N) 693-megawatt Unit 4 at the Turkey Point nuclear power station in Florida returned to full power by early Monday from 43 percent early Friday, the U.S. Nuclear Regulatory Commission said in a report.
The company reduced the unit to about 40 percent for planned testing, including turbine valve testing, and other maintenance last week.
The 2,196 MW Turkey Point station is located in Florida City in Miami-Dade County about 25 miles south of Miami.
There are several units at Turkey Point: the 398 MW oil/natural gas-fired Unit 1, the 400 MW oil/gas-fired Unit 2, two 693 MW nuclear units, 3 and 4, the 1,150 MW combined-cycle gas-fired Unit 5, and a handful of 2 MW and 3 MW oil-fired turbines.
Unit 1 entered service in 1967, Unit 2 in 1968, Unit 3 in 1972, Unit 4 in 1973 and Unit 5 in 2007. The NRC renewed the reactors original 40-year operating licenses in 2002 for another 20 years until 2036 and 2043.
Unit 3 continued to operate at full power.
One MW powers about 300 homes in Florida.
FPL plans to spend about $1.5 billion to add about 400 MW of capacity to the company's existing St. Lucie and Turkey Point reactors by 2012.
In 2009, FPL plans to file with the NRC to build two of Toshiba Corp (6502.T)/Shaw Group Inc's SGR.N Westinghouse Electric Co 1,100 MW AP1000 reactors at Turkey Point. FPL however has said it is also considering General Electric Co (GE.N)/Hitachi Ltd's (6501.T) 1,550 MW Economic Simplified Boiling Water Reactor technology.
If the company decides to go forward with the new reactors, it has said the new units, 6 and 7, could enter service in the 2018-2020 timeframe.
In filings with state regulators, FPL has said two AP1000 reactors and possible needed transmission upgrades could cost $12 billion-$18 billion while two of the larger GE reactors could cost $16.5 billion-$24.3 billion.
FPL, of Juno Beach, Florida, owns and operates about 38,000 MW of generating capacity across the United States, markets energy commodities, and transmits and distributes electricity to more than 4.5 million customers in Florida. (Reporting by Scott DiSavino; Editing by John Picinich)
