When completed later this year, the Solar Star facility near Rosamond, Calif. will be the world's largest solar power plant, with 579MW of power capacity. However, it's unlikely to hold that title for long (see McCoy Solar Energy Project).
The plant is made up of two co-located generating facilities, Solar Star I and II. Combined, the Solar Star Plant contains more than 1.7 million photovoltaic panels covering about 4,700 acres across two counties.
Built by MidAmerican Solar and SunPower Corp., the plant will be owned and operated by BHE Solar, a subsidiary of Berkshire Hathaway Energy owned by Warren Buffet.
When fully online later this year, it will provide enough electricity to power 255,000 average California households. It will also be able to displace about 570,000 metric tons of carbon dioxide annually, which is the equivalent of taking more than 100,000 cars off the road.
