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 (usually lower-price solar electricity during the daytime) for later use during periods of higher electricity demand (usually evening hours).
The battery energy storage facility at Moss Landing consists of two separate energy storage facilities. The first battery storage facility, known as the Vistra Energy Storage Facility is owned and operated by the Vistra Corp, and the second, known as the Elkhorn Battery Facility is owned and operated by California's PG&E utility company. The Elkhorn Battery Facility utilizes Tesla batteries to meet its energy storage needs.
The plant's two large 500′ tall stacks are local landmarks, visible throughout the Monterey Bay Area. Both the power generating plant and one of the battery storage facilities are owned and operated by the Irving, Texas based Vistra Corp. PG&E owns the second battery energy storage facility. The power generation plant currently has a capacity of 1020 MW (net) from its two combined cycle units. It was once the largest power plant in the state of California, with a generation capacity of 2560 MW, before its two large supercritical steam units were retired in 2016.
