Beacon BESS 1 is a battery energy storage system (BESS) located in Kern County, California. The plant has a total capacity of 20 MW and utilizes lithium-ion batteries (LIB) with a total storage capacity of 10 MWh, providing a duration of 0.5 hours. It began operating in 2018 and has one generator. The primary fuel type is listed as MWH, indicating it draws power from the grid to charge the batteries.
The facility is owned and operated by the Los Angeles Department of Water & Power (LADWP), which also serves as the balancing authority. It operates within the Western Electricity Coordinating Council (WECC) NERC region. Beacon BESS 1 ranks as the 184th largest power plant in California out of 300, and 683rd nationally out of 1205.

Capacity Factor
Positive values indicate net discharge (generation exceeds station load). Negative values indicate net charging. Pure battery storage plants are typically net negative due to round-trip efficiency losses.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
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.
