MidAmerican Energy Holdings, the electric utility owned by Warren Buffet's Berkshire Hathway group, announced today it had acquired a 579-megawatt solar development in Southern California.

The Antelope Valley Solar projects, which are actually two adjacent arrays in Kern and Los Angeles counties, will comprise the largest solar project in the world, according to the company's release, serving close to 1 million residents.

 

The previous record was held by NextEra's Mojave development with an operating capacity of 354 megawatts.
