A California Energy Commission (CEC) siting committee is recommending approval of the planned Imperial Valley Solar Project in Imperial County, Calif. The Imperial Valley Solar Project is being developed by Imperial Valley Solar LLC largely on public land managed by the federal Bureau of Land Management. The project site is located approximately 14 miles west of El Centro.

The primary equipment for the generating facility would include approximately 28,000 25 kW solar dish Stirling systems, or SunCatchers, consisting of a solar receiver heat exchanger and a closed-cycle, high-efficiency engine designed to convert solar power to rotary power and drive an electrical generator to produce electricity.
