latest news California Flex Alert will last even longer in the ongoing heat wave


As an unprecedented heatwave continues to strain California’s power grid, authorities have issued a ninth consecutive Flex Alert – this one is expected to last two hours longer than previous daily nationwide announcements. ‘state to limit power consumption.

Thursday’s flexible alert will begin at 3 p.m. and last until 10 p.m. due to changing conditions that power grid officials say could delay the supply of solar power. Flex Alert’s hours of operation for the past eight days have been from 4 p.m. to 9 p.m., during which the state narrowly avoided widespread power outages over several days.

“The main reason why we have extended [the alert is] largely due to some uncertainty about how much generation we will have from our renewable resources, primarily solar, in the mid-afternoon,” said Elliot Mainzer, President and Chief Executive Officer. General of the California Independent System Operator, which manages the state’s electrical grid. .

Smoke and cloud cover in northern California are expected to affect solar power supply, Mainzer said. A wildfire burning west of Lake Tahoe was sending smoke into the atmosphere.

He said California expects even higher power demands Thursday night compared to Wednesday, as temperatures across the state are expected to be a bit warmer. On Tuesday, California set an all-time energy record, with peak demand at 52,061 megawatts.

Cal ISO also released the first stage of its energy emergency alert for Thursday afternoon, which means “energy deficiencies are expected.”

Authorities are urging residents to pre-cool homes by 3 p.m., charge appliances and draw window blinds to block sunlight.

During the seven hours of the Flex Alert, Cal ISO officials are asking consumers to set thermostats to 78 degrees or higher, unplug unused appliances, turn off unnecessary lights and refrain from using major appliances.

“Last week was really, really, really tough, and I was so grateful and so impressed with how California electricity consumers came together,” Mainzer said. “They really stepped up…and really got us through what was an extraordinarily difficult time.”

Mainzer said he hopes the state is “on the verge of turning the corner” from the record-breaking heat wave and the strain on the power grid will soon ease.

The National Weather Service predicted that most extreme heat warnings across the state will expire by Saturday.
