California may soon be able to eliminate entirely fossil gas peaker plants because a combination of batteries, hydro, and imports (which themselves are 58% WindWaterSolar and growing) provide the exact same service but at a much lower cost and faster ramp rate (and more cleanly and safely).
@mzjacobson.bsky.socialPhenomenal!
Fossil gas has supplied only 3-5.6% of CAISO electricity each of the last 6 days, all in summer, and only 13.6% of electricity in all of 2026, DOWN 62% versus 2023.
Meanwhile, solar is up 54.4%, wind is up 16%, and batteries are up 337% in '26 v '23.
