Massive energy storage system gets connected to California power grid


A 300MW/1,200MWh energy storage system located on-site at Vistra’s Moss Landing Power Plant has been connected to the power grid in California.

The Moss Landing energy storage facility is said to be the largest of its kind in the world.

The storage system has the capacity to power approximately 225,000 homes during peak electricity pricing periods.

Powered by lithium-ion battery storage system, the facility is expected to an addition of another 100MW/400MWh by August 2021.

Construction on the expansion of the energy storage facility in underway.

Upon completion of the second phase, the Moss Landing facility will have a total energy storage capacity of 400MW.

California State Senator John Laird said, “As the largest of its kind in the world, the Vistra Zero Moss Landing Energy Storage Facility will store renewable energy, releasing it when it is needed most. It is meaningful, ambitious projects like these that will help to pave the way to a 100% clean energy future for California and the rest of the world.”

The energy storage facility is supported by long-term resource adequacy contracts with Pacific Gas and Electric Company (PG&E) for both of its phases.

“A battery system of this size and scale has never been built before. As our country transitions to a clean energy future, batteries will play a pivotal role and the Vistra Moss Landing project will serve as the model for utility-scale battery storage for years to come,” said Curt Morgan, chief executive officer of Vistra.
