California declares power emergency during heatwave 7/25/23

FOLSOM, Calif. – The California Independent System Operator (ISO) declared an Energy Emergency Alert (EEA) Watch, effective at 7:26 p.m. through 11:59 p.m. today, July 25.

The EEA Watch was issued due to higher than anticipated loads and temperatures across the grid. When an EEA watch is in effect, entities are encouraged to offer available energy and ancillary service bids, and participating customers may be directed by utilities to use generators approved for emergencies, or to reduce load according to the protocols of each utility's program.

The EEA Watch remained in effect even as conditions on the grid improved and grid operators were monitoring the situation.

If grid conditions were to worsen, the ISO could declare an EEA 1, 2, or 3. For more details on the different designations, view the emergency notifications fact sheet on our News webpage.
