PG&E proposes four energy storage projects, including world’s biggest battery
PG&E (PCG -0.4%) asks for approval to build four new energy storage projects totaling nearly 570 MW, including a 300 MW battery installation at a natural gas-fired power plant owned by Vistra Energy (NYSE:VST), joining a growing list of power companies investing in storing electricity.
VST says the battery project – which it would own – would be the largest of its kind in the world and would be capable of running for four hours while putting out the same amount of power as a small natural gas plant.
PG&E also is seeking approval for a 182.5 MW system built by Tesla, which would be owned by PG&E, as well two smaller projects.
Cost estimates for the projects are not provided.
If approved by the California Public Utilities Commission, PG&E says the first of its proposed projects should come on-line by the end of 2019, with the other projects scheduled to be ready by year-end 2020.
