Sempra Mexico Termoelectrica natgas unit shut

NEW YORK, Oct 21 (Reuters) - Sempra Energy's (SRE.N) 625-megawatt Termoelectrica de Mexicali natural gas-fired power station in Mexico shut by Monday afternoon for unplanned reasons, the California Independent System Operator said in a report.

The Termoelectrica de Mexicali combined-cycle station, which entered service in 2003, is located near Mexicali in Baja California, about 115 miles east of San Diego. It supplies the U.S. power market.

One MW powers about 700 homes in California.

Sempra owns and operates more than 3,000 MW of generating capacity, markets energy and other commodities around the world, and transmits and distributes electricity to 1.4 million and natural gas to 6.4 million customers in California. (Reporting by Scott DiSavino; Editing by John Picinich)
