This gives an explanation for what's happening and why:

"We told the California Public Utilities Commission of a 4,700-MW need through 2022 and that gap started in 2020. Despite all that, only 3,300 MW was authorized for procurement and none starting until 2021," Berberich said during a special telephone conference the Cal-ISO Board of Governors held Aug. 17, following a weekend during which the grid operator twice conducted rotating blackouts because of high demand and tightening reserves.
