Storage will replace 3 California gas plants as PG&E nabs approval for world's largest batteries

Approval of PG&E's landmark energy storage solicitation is the most significant example to date of batteries taking the place of fossil fuel generation on the power grid. 

Energy storage has helped decrease the California's reliance on gas for years, particularly since 2016, when regulators ordered accelerated battery procurements to counteract the closure of a natural gas storage facility outside Los Angeles. 

The PG&E projects, however, are the first time a utility and its regulators have sought to directly replace multiple major power plants with battery storage.
