California’s power grid may issue Flex Alert as scorching temperatures hit California – San Francisco Chronicle


Scorching temperatures baking some parts of California may mean that state residents will be asked to voluntarily conserve energy, officials said Sunday.

A heat bulletin from the California Independent System Operator said officials might issue a flex alert and ask consumers “to reduce electricity use during critical times of stress on the [power] grid.”

“Potential for resource shortfalls are projected for Monday, but could be made up in the day-ahead market running today for tomorrow, and through voluntary consumer conservation,” the bulletin said. 

The announcement came as some of the Bay Area’s inland communities — including Cloverdale, Lake Berryessa, Pinnacles and Parkfield — anticipated temperatures in the 90s to low 100s this week. Southern California may see temperatures as much as 15 degrees above normal, the statement said.

California’s hot forecast comes as the Pacific Northwest is blasted by historic blistering heat, with Oregon and Washington looking at potential all-time highs on Monday.

California Independent System Operator officials said they will monitor conditions and provide public updates.

If a flex alert is issued, consumers may be asked to avoid using major appliances, unplug unused appliances, use fans when possible, among other measures.
