NEW YORK - Calpine Corp's 724-megawatt Pastoria natural gas-fired power station in California returned to service by Tuesday afternoon, the California Independent System Operator said in a report.

The unit shut for planned reasons by Sept. 14.

The 724-MW Pastoria combined cycle station is located in Lebec in Kern County about 30 miles south of Bakersfield, California, on property leased from Tejon Ranch Corp.

There are three 156-MW combustion turbines at the station and two heat recovery steam turbines rated at 169 MW and 87 MW.

One MW powers about 700 homes in California.

Calpine, of Houston, owns and operates nearly 24,000 MW of generating capacity in operation and under construction and markets energy commodities in North America. (Reporting by Scott DiSavino; Editing by John Picinich)
