The Gas Utilization Facility, located in San Diego County, California, is a 6.1 MW hybrid power plant primarily fueled by other waste biomass (OBG). It began operating in 1985 and is owned and operated by the City of San Diego. The plant incorporates both conventional hydroelectric and other waste biomass technologies across its three generators.
The Gas Utilization Facility operates within the California Independent System Operator (CAISO) balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. In the most recent year of data, the plant generated 30,461 MWh, achieving a capacity factor of 57.0%. The plant holds a notable ranking as the 8th largest OBG-fueled plant in California out of 33 such plants, and ranks 13th nationally out of 74 plants using this fuel type.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
