PG&E, Vistra plan world’s largest battery storage unit

Renewables Now:

Texas-based Vistra Energy Corp will install a 300 MW/1,200 MWh battery storage facility in California, planned to be the largest one of its kind globally, under a deal with local utility Pacific Gas and Electric Co (PG&E).

Vistra Energy said on Friday it will develop the project under a 20-year resource adequacy contract with PG&E, which was filed last week for approval with the California Public Utilities Commission (CPUC). A decision on the application is expected to be issued within 90 days.

The proposed energy storage system will be located at the site of PG&E’s Moss Landing natural gas power station in California’s Monterey County. If CPUC approval is secured, Vistra expects to launch commercial operations at the facility by the closing quarter of 2020.

The storage facility will be interconnected through an existing link from mothballed units of the natural gas plant. The batteries, themselves, will be accommodated in an existing turbine building at the site.

The project was part of a larger solicitation for energy storage capacity under which PG&E selected a total of four projects with a combined capacity of 567.5 MW. PG&E expects all of the facilities to be commissioned by end-2020. The first one will be put on stream by the end of next year.
