RRI Energy Stops Output at Etiwanda Unit in California

RRI Energy Inc., a Houston-based power producer, stopped output at a natural gas-fired electricity unit in California.

The 320-megawatt Etiwanda Generating Station Unit 4 was offline as of 3:15 p.m. local time today, the California Independent System Operator said in a status report.

The shutdown was because of a temporary operational constraint during a normal transition from one operating range to another, according to the report.

The unit was operating at full capacity at the same time yesterday, a previous report showed.

The generator is part of a 640-megawatt station that is located east of Los Angeles in Rancho Cucamonga.

One megawatt can power 800 typical U.S. homes.
