Tierra Buena Energy Storage is a 5 MW battery energy storage system located in Sutter County, California. The plant began operating in 2022 and is owned and operated by VESI 10 LLC. It consists of two generators utilizing battery technology, with a total storage capacity of 2.5 MWh. The battery chemistry is lithium-ion (LIB), providing a storage duration of 1 hour.
The facility operates within the California Independent System Operator (CAISO) balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. Tierra Buena Energy Storage is ranked as the 227th largest power plant in California out of 300, and 990th nationally out of 1205 facilities. The plant's primary fuel source is electricity (MWH), indicating it charges from the grid and discharges during periods of high demand or grid instability.

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.

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.
