Due to a persistent, record-breaking heat wave in California, the California Independent System Operator (CAISO) says customers should be prepared for the possibility of rotating power outages through at least Wednesday, August 19 during the late afternoon and evening hours. A statewide Flex Alert, which is a call for voluntary electricity conservation, has been issued through Wednesday, August 19 between 3:00 PM and 10:00 PM daily. If a large number of consumers conserve energy, it can reduce demand and strain on the power grid and help avoid or reduce power outages.
Reduce energy usage 3:00 PM to 10:00 PM
- Pre-cool homes at 72°F overnight and in the morning
- Close blinds to keep out the afternoon heat
- Turn your air conditioner to 78°F or higher between 3:00 PM to 10:00 PM
- Avoid major appliance use and unplug unused electrical devices between 3:00 PM to 10:00 PM
