August 3, 2023: Energy firm Vistra announced on August 1 it had completed the expansion of its now 750MW/3,000MWh Moss Landing energy storage facility in California.
Vistra said the third phase expansion, which added 350MW/1,400MWh to the lithium ion facility’s capacity, had entered commercial operation on June 2 and is storing power and releasing it to California’s grid.
The third phase expansion comprises 122 individual containers that together house more than 110,000 battery modules.
Moss Landing Energy Storage Facility is co-located on the site of Vistra’s existing natural gas-fuelled power plant in Monterey County.
Texas-based Vistra opened Moss Landing in January 2021, hailing the then 300MW/1,200MWh system as the largest such facility in the world.
In addition to its California assets, Vistra owns and operates two solar facilities, one solar-plus-storage facility, and a 260MW storage facility, all in Texas.
Vistra says it also has a pipeline of projects, including four solar installations and 10 other storage and solar-plus-storage facilities, all in various stages of development in Illinois and Texas.
