# California AB 1921 (20232024) — Energy: renewable electrical generation facilities: definition.

Existing law defines a "renewable electrical generation facility" as a facility that uses biomass, solar thermal, photovoltaic, wind, geothermal, fuel cells using renewable fuels, small hydroelectric generation of 30 megawatts or less, digester gas, municipal solid waste conversion, landfill gas, ocean wave, ocean thermal, or tidal current, and that meets other specified requirements. Existing law incorporates that definition into various programs, including the California Renewables Portfolio Standard Program, which requires the Public Utilities Commission to establish a renewables portfolio standard requiring all retail sellers, as defined, to procure a minimum quantity of electricity products from electrical generating facilities that meet the definition of "renewable electrical generation facility," and the net energy metering program, in which residential customers, small commercial customers, and commercial, industrial, or agricultural customers of an electrical utility, who use a renewable electrical generation facility, are eligible to participate, as specified.
