Diablo produces electricity 24/7/365. Will have to have a lot of grid storage to make up for thatIt was set to close in 2025 but within recent months legislature has been pushing to keep it open five years longer. Diablo Canyon produces 2,250MW, nearly 9% of California's electricity last year and ~15% of the state's clean energy production.
But as mentioned a couple posts ago, most of this will be covered. The California Energy Commission is planning 2,000-5,000 MW of offshore wind by 2030 and 25GW by 2045. Aside from this, increasing amounts of utility scale and residential combined solar PV + grid battery storage will continue to roll out for many years to come.
