S&P Capital IQ ($):

Pacific Gas and Electric Co. has filed a request to add nine battery storage contracts totaling nearly 1,600 MW/6,400 MWh of capacity to come online by 2024, the PG&E Corp. operating arm announced Jan. 24.

The utility, known as PG&E, proposed the projects to the California Public Utilities Commission in response to the regulator’s landmark order for load-serving entities to add 11.5 GW of clean energy resources between 2023 and 2026 to help offset the retirement of several aging natural gas-fired power plants and PG&E’s Diablo Canyon nuclear power station, which is the Golden State’s largest source of electricity.

PG&E proposed 15-year contracts for the projects, which are all four-hour lithium-ion battery resources. The projects will participate in California ISO wholesale markets, supplying energy and ancillary services like operating reserve to help support grid reliability, according to PG&E.

The utility now has contracts for more than 3,300 MW of battery storage through 2024. The 2,240-MW Diablo Canyon plant is scheduled to retire in two phases in 2024 and 2025.
