California approved one of the the biggest installations of battery-based energy-storage systems in the U.S. as the state moves to add power resources to its grid after suffering from rolling blackouts.

The California Public Utilities Commission signed off on previously announced utility contracts for nearly 1.2 gigawatts of battery storage capacity that is expected to be in service by August of next year. The commission’s vote comes less than two weeks after California’s grid operator imposed power shutoffs that left millions in the dark during a record heat wave.
