The California grid ran on 100% renewables with no blackouts or cost rises for a record 98 days

No blackouts occurred when renewable electricity supply exceeded 100% of demand on California's main grid for parts of 98 of 116 days.

The period occured in 2024 between late winter and early summer. "Compared to the same period in 2023, solar output in California is up 31%, wind power is up 8%, and batteries are up a staggering 105%."
