PG&E Corp's (PCG.N) 1,150-megawatt Diablo Canyon 2 nuclear power unit in California was at 77 percent power early Thursday, down from full power on Wednesday, the U.S. Nuclear Regulatory Commission said in its power reactor status report.

The unit, in Avila Beach, about 195 miles northwest of Los Angeles, had just returned to full power from a recent outage.

The adjacent 1,150-MW Unit 1 continued to operate at full power on Thursday, the NRC report said.

One MW powers about 700 homes in California.

PG&E, of San Francisco, owns and operates more than 6,200 MW of generating capacity, markets energy commodities, and transmits and distributes electricity to almost 5.3 million customers and natural gas to 4.2 million customers in California. (Reporting by Eileen Moustakis; editing by Jim Marshall)
