RRI Energy Inc., a Houston-based electricity producer, cut output at a southern California power plant.
The company’s Mandalay Generating Station’s 215-megawatt Unit 1 was offline in an unplanned shutdown as of 3:15 p.m. local time today, the California Independent System Operator said in a report.
The unit was operating at full capacity at the same time yesterday, a previous report showed.
The plant’s 215.3-megawatt Unit 2 idled 65.3 megawatts, or 30 percent of capacity, for unplanned reasons for a second day, reports showed.
The power station, which burns natural gas, is located in Oxnard, California. It has three generating units with a total capacity of 560 megawatts, according to the company’s Web site.
One megawatt can power about 800 typical U.S. homes.
