NEW YORK - Southern California Edison's 1,070-megawatt Unit 2 at San Onofre nuclear power station in California ramped up to 98 percent by early Friday from 60 percent early Thursday after exiting an outage, the U.S. Nuclear Regulatory Commission said in a report.
The company shut the unit by Sept. 14 to work on the cooling-water system.
It plans to shut the unit in late September for about three months for refueling and steam generator replacement.
The 2,150 MW San Onofre station is located in San Clemente in San Diego County, about 60 miles north of San Diego. There are two units at the station, the 1,070 MW Unit 2 and 1,080 MW Unit 3, which entered service in 1983 and 1984.
Unit 3 continued to operate at full power.
One MW powers about 700 homes in California.
So Cal Ed, a subsidiary of Edison International, operates the station for its owners: So Cal Ed (78.21 percent), Sempra Energy's (SRE.N) San Diego Gas & Electric subsidiary (20 percent) and the city of Riverside, California (1.79 percent).
Edison International, of Rosemead, California, owns and operates about 14,000 MW of generating capacity and transmits and distributes electricity to about 4.8 million customers in central and Southern California. (Reporting by Scott DiSavino; Editing by John Picinich)
