Edwards Sanborn E2 is a hybrid power plant located in Kern County, California. The plant, which came online in 2021, is owned and operated by Terra-Gen Operating Co-Hybrid. It has a total capacity of 257.8 MW and consists of two generators utilizing both solar photovoltaic and battery storage technologies. The battery energy storage system (BESS) has a capacity of 250 MWh and a duration of 2.08 hours, employing lithium-ion battery chemistry (LIB). The solar component uses dual-axis tracking.
The plant operates within the California Independent System Operator (CAISO) balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. In its latest year of operation, Edwards Sanborn E2 generated 300,808 MWh, resulting in a capacity factor of 13.3%. The plant is ranked as the 47th largest in California out of 112 plants and 190th nationally out of 514 plants. Financial data is available for the plant from LBNL, and it has been featured in 10 news articles, primarily covering industry and grid-related topics.

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.
