(Sacramento, Calif., November 3, 2022) — A new report from the California Independent System Operator (CAISO) examines the events that threatened grid reliability in California during the unprecedented late-summer heat wave.

CAISO says its Summer Market Performance Report for September 2022 intends to identify factors that supported grid reliability during the emergency as well as areas of improvement needed in system operations.

Barry Moline, executive director of the California Municipal Utilities Association (CMUA), issued the following statement in response to the report's findings:

“California climate and clean energy policy is leading the world, and while collective action helped avoid rolling blackouts during the September heat storm, this incident brought us uncomfortably close to that possibility.
“Preparing for such an event this summer, publicly owned electric utilities and water agencies coordinated closely with the Governor’s Office, California Energy Commission, and the California Independent System Operator. We worked diligently to locate, confirm and generate firm power with every available back-up generator; facilitated customer conservation at key times; and pushed existing power supply to its limit. Only by working together did we avoid major disruption.
“Going forward, publicly owned electric utility and water and wastewater agencies will continue to coordinate closely with the Administration and CAISO to decarbonize while assuring that California has the infrastructure and power supply it needs to provide affordable and continuous power.” 

CAISO has scheduled a stakeholder call on November 17, 2022, to review details of the report's analysis and answer questions.
