Oakland Energy Storage Facility
Vistra is redeveloping its Oakland Power Plant into a 74 MW/294 MWh zero-emission energy storage facility.
The redevelopment project includes the decommissioning and demolition of the three existing fossil fuel-powered units to make room for the installation of a battery energy storage system, which will produce enough energy to power 60,000 homes for four hours.

Project milestones
Here is what is currently underway in Oakland.
2021
The two combustion turbines of Unit 2 that run on diesel fuel were decommissioned and demolished in 2021—making room on site for Phase 1 of the BESS project.
2022
Currently, the remaining Units 1 and 3 of three combustion turbines are required to operate under a Reliability Must Run (RMR) contract with CAISO, the state’s grid operator. Vistra is working with PG&E and CAISO to retire these units. Phase 2 of the BESS project may proceed once the existing units are retired and demolished.
2025
For Phase 1 of the project, we expect to have 43.25 MW/140MWh of clean energy completed by summer 2025. This part of the project will replace Unit 2.
Beyond 2025
For Phase 2 of the project, we expect to have 38.5MW/154MWh of clean energy with a completion date yet to be determined. This part of the project will replace Units 1 and 3.
