Vistra completes phase III expansion of Moss Landing Energy Storage Facility

Texas-based power company Vistra Corp. on Tuesday announced the completion of phase III 350MW/1400MWh expansion of the Moss Landing Energy Storage Facility in California.The phase III expansion brings the total capacity of the Moss Landing Energy Storage facility to 750 MW/3,000 MWh – making it the largest energy storage facility in the world. 

While the phase III expansion achieved commercial operation on June 2, storing and releasing power to California grid, beginning August 1, the company will operate under a 15-year resource adequacy agreement with Pacific Gas and Electric Company (PG&E) functioning to strengthen California's grid.

"As we navigate this energy transition to cleaner fuel sources, the ability to balance that shift with both reliability and affordability is paramount," said Jim Burke, President and CEO of Vistra.

"Continued investment in energy storage, like our Moss Landing site, allows us to harness and store a substantial and growing amount of power from intermittent renewables and then deliver that electricity when customers need it most."

Phase III of the project is made up of 122 individual containers which house more than 110,000 battery modules and like few of the other energy storge projects by Vistra, the enormous lithium-ion battery storage project is co-located at a site previously being used for electricity production.

With the commissioning of the latest project, Vistra owns the second-most energy storage capacity in the US, the company claimed.

In addition to its California assets, Vistra owns and operates two solar facilities, one solar-plus-storage facility, and a 260-MW storage facility, all in Texas. Moreover, it several projects, in the pipeline including four solar installations and 10 other storage and solar-plus-storage facilities at various stages of development in Illinois and Texas.
