PG&E shuts Calif. Gateway natgas unit

NEW YORK, June 1 (Reuters) - PG&E Corp (PCG.N) shut the 530-megawatt Gateway natural gas-fired power plant in California for planned reasons, the California Independent System Operator said in a report.

The Gateway station, which entered service in 2009, is located in Antioch in Contra Costa County about 45 miles east of San Francisco.

PG&E took over Gateway from Mirant Corp (MIR.N) as part of a settlement of overcharges for power sold during the 2000-01 Western power crisis. It was to be Unit 8 at Mirant's Contra Costa plant.

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 northern California.
