As the heat wave continues through Southern California, another statewide Flex Alert has been issued for Monday, from 4 p.m. to 9 p.m. to help stabilize the state’s electric grid.

The California Independent System Operator also issued a Flex Alert over the weekend on Friday and Saturday.

The fast-moving Bootleg Fire tripped off transmission lines on Friday and again Saturday, limiting electricity flow from the Pacific Northwest to California and other states, the ISO said in a news release.

In addition, the ISO issued a Restricted Maintenance Operations (RMO) for Monday that requires generators to postpone any planned outages for routine equipment maintenance, ensuring that all available resources can be dispatched to the grid, the release said.

A Flex Alert is typically issued by the ISO when the electric grid is under stress because of generation or transmission outages, or from persistent hot temperatures.

It is a call to residents to conserve energy to avoid power disruptions and rolling blackouts, according to the ISO, which runs most of the state’s electric grid.

Consumers are encouraged to take these specific actions from 4 p.m. to 9 p.m. while the Flex Alert is in effect:

Precautions can also be taken prior to the start of the Flex Alert, according to the ISO. They suggest consumers can:

Statewide Flex Alert issued for Monday due to wildfires, heat

KSBY San Luis Obispo News 12 July, 2021 - 01:10pm

Wildfires and a heatwave on the West Coast is forecasted to impact California's electric grid at the beginning of this week.

The California Independent System Operator issued a another (ISO) statewide Flex Alert has been issued for Monday, July 12th from 4 p.m. to 9 p.m.

The fast-moving Bootleg Fire burning in Oregon knocked transmission lines Friday and Saturday which limited electricity for from the Pacific Northwest to California and other states, according to state operators.

Officials said the power supplies to the California service area, about 80% of the state, have been reduced by 3,500 megawatts due to the fire.

That combined with the excessive heat across the state is driving up demand for electricity.

People are asked to conserve as much electricity as possible between 4 p.m. and 9 p.m. to reduce stress on the grid during those peak hours.

Yesterday, Governor Gavin Newsom signed an executive order to quickly secure additional power that has helped maintain grid stability through the weekend. The executive order remains in place.

If electricity demand exceeds supple, the ISO said it could order utility companies to issue rotating power outages for a short duration.

Toasty temperatures prompted the Bay Area National Weather Service to issue an excessive heat warning and heat advisory for most of the Bay except the immediate East Bay Shoreline, the Coast and San Francisco.

Both weather alerts were in effect until Sunday at 11 p.m.

Today, some areas will pop 100+, and the Bay will see 70’s take over for good coverage.

For the work week, a new weather pattern will drive cooling systems from the Northwest.

Temps will slide all week and settle by Friday. There doesn’t appear another pop by the weekend, but a few 90’s well Inland will remain by next weekend.

The National Weather Service urges people to stay safe by keeping cool and hydrated.

CA Swelter Shatters Temperature Records Across The State

Patch.com 11 July, 2021 - 02:44pm

CALIFORNIA — Another sweltering heat wave rippled across the Golden State this weekend, raising record high temperatures as firefighters battled wildfires in searing conditions. The volatile combination of extreme weather and wildfires also threatened California's transmission lines and power grid, prompting the state to issue a second consecutive Flex Alert on Saturday.

And Californians could be asked to conserve energy yet again Monday as the heat wave continues.

Over the weekend, fire agencies remained on high alert amid elevated wildfire danger, and officials reminded Californians to drink plenty of water, stay cool and keep pets safe.

Some of the hottest temperatures were clocked in Palm Springs, Borrego and Desert Valley. In Palm Springs, a record high of 120 was recorded on Saturday and Borego reached 118 degrees. Temperatures topped 130 degrees in Death Valley on both Friday and Saturday, and temperatures were expected to hit 130 again on Sunday. The desert area is known for the Earth's hottest recorded temperature of 134 degrees in 1913.

On Saturday, more record highs were recorded across Central and Southern California:

On the Central Coast, the Paso Robles Airport hit a staggering 115 degrees on Saturday afternoon, breaking a 114 degrees record set 60 years ago, according to John Lindsey, a marine meteorologist for PG&E.

More record highs were recorded across Northern California:

In California's agricultural Central Valley, 100-degree temperatures blanketed the region, with Fresno reaching 111 degrees, just one degree short of the all-time high for the date. And while temperatures were elevated for coastal populations, many of those regions evaded extreme conditions.

On Saturday, circumstances intensified after officials learned that a rapidly spreading Bootleg Fire in Southern Oregon was threatening transmission lines used to power the Golden State.

Transmission lines were reportedly knocked out by the fire on Saturday, reducing power supplies by 5,500 megawatts over the weekend. But officials said grid conditions for Sunday were projected to be stable. CAISO maintained that a third consecutive Flex Alert would not be issued.

"Conservation efforts worked yesterday. California residents and businesses did it again. The California ISO thanks you for your conservation efforts," CAISO tweeted Sunday.

An excessive heat warning is in effect in the Antelope Valley through 9 p.m. Monday, with the NWS predicting "dangerously hot conditions with temperatures up to 113 expected."
