SAN DIEGO (KGTV) - Californians are asked to conserve power this week during the hottest days of the heat wave.
The California Independent System Operator Corporation issued a statewide Flex Alert from 5 p.m. to 9 p.m. Tuesday and Wednesday.
Customers are asked to turn off unnecessary lights, avoid using major appliances, and set air conditioners to 78 degrees or higher.
The ISO said the high temperatures, along with reduced electricity imports, tight natural gas supplies, and high wildfire risk led to the Flex Alert demand.
All possible resources will be available to serve the demand but conservation is needed to avoid rotating power outage, ISO officials said.
