The California ISO’s market watchdog released a report last week detailing the market’s performance during the August 2020 blackouts there. The new report confirms many of the same conclusions in the joint report issued on November 24th by the CAISO, CPUC and CEC. These conclusions include the record west-wide extreme temperatures, inadequate reserve margins and overestimation of resources that count as resource adequacy (RA) capacity.

The report found that in-state hydro performed at about 91% of its RA obligation, almost twice the level of wind and solar resources. Hydropower is an essential part of reliable renewable energy in any region.
