May 20 (Renewables Now) - US utility Pacific Gas and Electric Company (PG&E) is seeking regulatory consent to add 423 MW of energy storage capacity to enhance the reliability of California’s electric system.

The five projects were selected in a competitive round that the US utility held in February so as to address potential grid reliability issues that were previously identified by the California Public Utilities Commission (CPUC). The battery storage will facilitate the integration of more renewable energy capacity, PG&E said on Tuesday. The permission has to be issued by CPUC.

The following table contains more details on the five selected projects. All of them will feature lithium-ion battery energy storage systems (BESS) and will be brought online by August 2021.

Project name Developer Location Contracted capacity (MW) Term of contract (years) Co-location technology
Diablo Energy Storage Diablo Energy Storage LLC Contra Costa County 150 15 No
Vistra Energy MOSS100 Energy Storage Dynegy Marketing and Trade LLC Moss Landing, Monterey County 100 10 No
Gateway Energy Storage Gateway Energy Storage LLC San Diego 50 15 No
Blythe Energy Storage 110 NextEra Energy Resources Development LLC Blythe, Riverside County 63 15 Solar PV
Coso Battery Storage Coso Battery Storage LLC Little Lake, Inyo County 60 15 Geothermal

PG&E was authorised to procure at least 716.9 MW of system reliability resources that will be commissioned between August 1, 2021 and August 1, 2023. The overall capacity will be reached through a second competitive solicitation due to be issued this summer for facilities going online within the period from August 1, 2022 to August 1, 2023.
