LAIST: Why the heat wave hasn't taken down the state's power grid [View all]

July has brought record-breaking heat for this time of year to much of the Southland, mostly inland. But we haven’t been hit with flex alerts or concerns about rolling power outages due to a boost in battery storage.

More battery storage: The state has nearly doubled its amount of battery storage in just the last two years. That’s kept the grid stable during hot evenings when solar power declines. Increased coordination and cooperation around the state and the West also helped. California has even had energy left over to share with other western states facing electricity shortages, helping avoid outages even when a power demand record was broken on the broader western energy grid.

The background: The last time we had flex alerts — calls to voluntarily conserve energy — was during a record-long heat wave in early September 2022. The state avoided rolling power outages because people heeded the call to conserve energy. And the last time we had rolling power outages was in 2020, when wildfires and heat put record strain on the power grid.
