A Flex Alert has been issued by the California Independent System Operator Corporation (ISO) for Tuesday and Wednesday due to high temperatures across the region.
The alert calls for California residents and most of the western U.S to conserve electricity from 5 p.m. to 9 p.m. during these days.
Flex Alerts are issued when the electricity grid is overtaxed due to high temperatures, the ISO said.
In San Diego County, temperatures on Tuesday and Wednesday are expected to reach about 86 degrees, according to the National Weather Service.
Other factors such as limited natural gas supplies, high wildfire risks and fewer electricity imports also contribute to the current warning.
To help conserve electricity over the next few days, the ISO asks customers to set thermostats to 78 degrees or higher and using fans to cool homes.
They also advise homeowners use major appliances in the morning or late evening and turn off lights and appliances that aren’t necessary.
More information about Flex Alerts can be found on the California ISO’s website.
