The Moss Landing Power Plant is a natural gas powered electricity generation plant as well as a battery energy storage facility, located in Moss Landing, California, United States, at the midpoint of Monterey Bay. As of 2025, the site's battery storage facility is one of the largest in the world, at 630 MW (power) and 2,500 MWh (energy). The energy storage facility stores excess electricity for later use during periods of higher electricity demand.
Read more on WikipediaThe Dynegy Moss Landing Power Plant Hybrid is a 2148 MW hybrid power plant located in Monterey County, California. The plant, owned by Vistra and operated by Dynegy-Moss Landing LLC, began operating in 2002 and utilizes both natural gas-fired combined cycle technology and battery storage. The facility has 9 generators and is fueled primarily by natural gas (NG). It is the largest power plant out of 76 in California, and ranks 25th out of 945 nationally.
The plant includes a battery energy storage system (BESS) with a total storage capacity of 1200 MWh and a duration of 4 hours. The BESS uses lithium-ion battery (LIB) chemistry. The Dynegy Moss Landing Power Plant Hybrid operates within the California Independent System Operator (CAISO) balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. The latest annual generation data indicates an output of 2,068,002 MWh, resulting in a capacity factor of 11.0%.

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.
