The California Renewable Portfolio Standard Program (“RPS” or “RPS Program”) was established by Senate Bill (“SB”) 1078, and has been subsequently modified by SB 107, SB 1036, SB   2-1X, and SB 350 set forth new RPS requirements applicable to publicly owned utilities (“POU”).  VMUS, as a POU, must comply with the RPS Program.  

The RPS Program requires California’s electric utilities and other retail sellers to procure eligible renewable energy resources (“ERRs”) so that the amount of electricity generated from eligible renewable resources equals or exceeds a specified percentage of the total electricity sold to retail customers in California.

Fuel cells using renewable fuels

Ocean wave, ocean thermal, and tidal current





Hydroelectric incremental generation from efficiency improvements

Small hydroelectric (30 megawatts or less)

Conduit hydroelectric

Landfill gas
