Pacific Gas and Electric Company (PG&E) has requested California Public Utilities Commission (CPUC) to approve six battery energy storage projects. These projects totaling 387 MW of capacity will help in integrating clean energy while ensuring future reliability of the grid. They complete PG&E’s procurement requirements outlined in a November 2019 CPUC decision, which authorised PG&E to procure at least 716.9 MW of system reliability resources to come online between August 1, 2021 and August 1, 2023.

In May 2020, PG&E announced the results of its first round of procurement: 423 MW of battery energy storage capacity, scheduled to be online by August 2021. The project agreements resulted from a competitive request for offers PG&E launched in July 2020. The six new projects all feature lithium-ion battery energy storage technology, each with a four-hour discharge duration.

The AMCOR project, the Lancaster Battery Storage project, and the LeConte Energy Storage project with a total capacity of 194 MW, are scheduled to come online by August 2022. The North Central Valley Energy Storage project and both Daggett projects aggregating 193 MW are scheduled to be online by August 2023.

The AMCOR, Lancaster and LeConte projects—totaling 194 MW—are scheduled to come online by August 2022, whereas, the North Central Valley and both Daggett projects— totaling 193 MW—are scheduled to be online by August 2023.
