The Desert Sunlight solar thin-film PV project, to be located near Desert Center in eastern Riverside County, California, will have a total capacity of 550 MW.
The other 250 MW portion of the solar PV thin-film project is already under contract to Southern California Edison.
Construction of the utility-scale solar thin-film PV facility is expected to start by the end of 2010 with completion around 2013.
First Solar's power purchase agreements with PG&E and SCE are subject to the approval of the California Public Utilities Commission.
