The Silverstrand Grid Energy Storage System is an 11 MW battery energy storage facility located in Ventura County, California. The plant, owned and operated by Silverstrand Grid, LLC, commenced operations in 2021. It is interconnected to the California Independent System Operator (CAISO) balancing authority within the Western Electricity Coordinating Council (WECC) region.
The facility utilizes batteries as its primary fuel source (MWH) and consists of a single generator. The battery energy storage system (BESS) has a total storage capacity of 44 MWh, providing a duration of 4 hours. The battery chemistry is lithium-ion (LIB). In California, the Silverstrand Grid Energy Storage System ranks as the 194th largest of 300 power plants in the state, and nationally it ranks 734th out of 1205 plants.

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.
