The PPAs must still be approved by the California Public Utilities Commission (CPUC).

SCE's Vice President of Renewable and Alternative Power stated in FRV's press release, "Utility-scale solar is an important element in reaching California renewable energy goals....FRV will help SCE continue to be the largest purchaser of solar power in the United States and we're delighted to contract with FRV on these projects."

SCE executed three PPAs, totaling 711 MW, with SunPower. The associated projects are: Solar Star California XIII LLC, a 110-MW project sited in Los Banos, with a target to be operational by December 31, 2014; Solar Star California XIX LLC, a 325-MW project sited in Rosamond, with a target to be operational by October 31, 2016; and Solar Star California XX LLC, a 276-MW project sited in Rosamond, with a target to be operational by October 31, 2016.

SCE's four PPA's with FRV have a total generating capacity of 120 MW.
