SunEdison, a unit of MEMC Electronic Materials, signed a new 25-year power purchase agreement (PPA) to deliver 20 MW to Riverside Public Utilities, the municipal electric utility of the city of Riverside, California.
Riverside is among the first of California's municipal utilities to enter into a utility-scale solar contract of this size. Under Senate Bill X 1-2, California extended its renewable portfolio standards (RPS) program goal to 33 percent and included publicly-owned utilities such as Riverside.
In addition to the contract from RPU, SunEdison also was awarded 3 PPAs totaling 48 MW by Southern California Edison (SCE) and one 18.5 MW PPA by San Diego Gas and Electric (SDG&E) under the Renewable Auction Mechanism program.
The California Public Utilities Commission (CPUC) approved the SCE contracts effective October 31, 2012 and is currently reviewing the SDG&E contract. The RAM program requires that projects start operating 24 months after CPUC approval.
