The Chestnut power plant, located in Kings County, California, is a hybrid solar and battery energy storage system (BESS) facility with a total capacity of 285.6 MW. Operated by Castanea Project LLC, the plant began commercial operation in 2023 and ranks as the 42nd largest power plant in California (out of 112) and 175th nationally (out of 514). The facility utilizes both solar photovoltaic technology with single-axis tracking and lithium-ion battery storage. The BESS component has a storage capacity of 540 MWh and a duration of 4 hours. The plant's primary fuel type is listed as "MWH" in the data.
Chestnut 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, the plant generated 377,844 MWh, achieving a capacity factor of 15.1%. Financial data indicates that the plant has a power purchase agreement (PPA) price of $45.03 per MWh, according to data from Lawrence Berkeley National Laboratory (LBNL). The plant consists of 2 generators.

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.
