What is a Flex Alert in California?
A Flex Alert is a call to residents to voluntarily conserve energy when demand for power could outstrip supply — which generally occurs during heat waves — to avoid power disruptions and rolling blackouts, according to the California Independent System Operator, which runs most of the state's electric grid.

California’s electric grid operator urged residents to voluntarily conserve energy for a second straight evening as extreme heat and a fast-growing wildfire in southern Oregon strained the state’s power supply Saturday.
The California Independent System Operator issued its Flex Alert through 9 p.m., calling for cuts in an effort to keep the state’s electric grid stable and avoid the need for rolling power outages.
Officials with the California ISO said that conditions on the state’s electric grid were “already a challenge” on Friday when triple-digit temperatures were recorded across the state and demand for power was surging. Then on Friday afternoon, the Bootleg Fire, the blaze that is burning in southern Oregon, began threatening transmission lines that bring power to California.
In a media briefing Saturday afternoon, California ISO officials said that 5,500 megawatts of power was lost because lines leading to the California Oregon Intertie were taken offline. One megawatt typically powers a few hundred homes with California’s total demand projected to peak Saturday at about 40,000 megawatts, according to the California ISO.
As of Saturday afternoon, the Bootleg Fire had burned 76,897 acres.
Gov. Gavin Newsom on Saturday night signed an executive order to free up energy capacity for the state. The directive built upon a similar order signed Friday, which suspended permitting requirements to allow the use of back-up power generation, by allowing the use of auxiliary ship engines to augment the power grid.

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.
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.
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:
An excessive heat warning remained in effect on Sunday, according to the National Weather Service.
Triple digit temperatures are expected in parts of Southern California with the threat of fire danger in some areas, according o the NWS.
The NWS advise residents to take precautions during these high temperatures by drinking plenty of fluids, staying in an air-conditioned room and out of the sun, check up on relatives and neighbors and wear lightweight and loose fitting clothing when possible.
The #HEATWAVE will continue through Monday, with highs well into the 100's over interior areas. In addition, elevated to brief fire conditions will affect the interior. Use caution! #SoCal #CAwx #LAheat pic.twitter.com/k4P1oTeQ9C
With transmission lines from Oregon still unreliable due to #BootlegFire & continued high temperatures, the California ISO issued a statewide #FlexAlert for Monday, July 12, from 4-9 p.m. Consumers are urged to #conserveenergy to help stabilize the grid. https://t.co/PQHFuzyHyx pic.twitter.com/PZtz8SE4Xn

Police in Riverside are searching for the killer who fatally shot a father of three young children early Saturday at an apartment complex.
The victim, who was identified by family members as 23-year-old Raul Hernandez, was gunned down around 12:30 a.m. at his apartment complex on the 5400 block of Olivewood Avenue, the Riverside Police Department told KTLA.
Many young people took part in the afternoon protest in the capital, which disrupted traffic until police moved in after several hours and broke up the march when a few protesters threw rocks.
From afar, Marrs empathized with the Florida teams searching the debris that was once the 12-story Champlain Tower South condominium complex. The scenes in Surfside brought back memories of the urgent search for survivors after the Oklahoma City bombing, followed by the heartbreak of pulling out nothing but bodies, he said.

CALIFORNIA — The Golden State extended its Flex Alert Saturday and asked residents to conserve energy for a second consecutive day as a rapidly spreading wildfire in Southern Oregon threatened vital transmission lines used to power California.
The alert from the California Independent System Operator originally came down Friday and asked residents to conserve energy from 4 to 9 p.m. On Saturday, CAISO again asked residents to lower thermostats and continue to conserve power during the evening hours.
Rolling outages were possible for the state yet again on Saturday, but officials said conservation could save CAISO from having to pull the plug on residents as a last resort.
The news comes as a weekend swelter bears down on California. Triple-digit heat plagued much of the state on Friday, posing a significant challenge for the electric grid. Also on Friday, Death Valley National Park in California recorded a blazing high of 130 degrees and could reach the same high on Saturday and Sunday.
The 130-degree reading would be the hottest high recorded there since July 1913, when the same Furnace Creek desert area hit 134 F (57 C), considered the highest reliably measured temperature on Earth.
The National Weather Service warned the dangerous conditions could cause heat-related illnesses across the state. And while mounting heat contributed to the possibility of rolling blackouts for a second day, the Bootleg Fire burning in Southern Oregon proved to be a wildcard for grid operators Saturday.
"Conditions deteriorated quickly as the Bootleg Fire continued to grow and posed an imminent threat to transmission lines leading into the California Oregon Intertie," CAISO said.
The wind-fanned blaze, which has burned more than 76,000 acres, has forced evacuations and was not projected to be contained for another two weeks. The fire doubled in acreage burned in less than 24 hours, officials said.
Gov. Gavin Newsom issued an emergency proclamation on Friday suspending some rules to allow for more power capacity.
Californians are asked to voluntarily conserve electricity from 4 to 9 p.m.
When Flex Alerts were called in mid-June and during last summer in August and September, consumers significantly reduced energy use greatly limiting rotating power outages.

Triple digit temperatures across the Bay Area sent people searching for an air conditioner and shade.
The National Weather Service warned the dangerous conditions could cause heat-related illnesses, while California’s power grid operator issued a statewide Flex Alert from 4 p.m. to 9 p.m. Saturday to avoid disruptions and rolling blackouts.
The California Independent System Operator warned of potential power shortage, not only because of mounting heat, but because a wildfire in southern Oregon was threatening transmission lines that carry imported power to California.
Gov. Gavin Newsom issued an emergency proclamation on Friday suspending rules to allow for more power capacity, and the ISO requested emergency assistance from other states. On Saturday, Newsom issued another proclamation allowing the emergency use of auxiliary ship engines to relieve pressure on the electric grid.
After 9 p.m. Saturday, the California ISO tweeted that the state managed to avoid rolling blackouts after they issued a Flex Alert.
Meanwhile, the extreme heat ended up searing profits for many Bay Area businesses, especially in Brentwood where it was a whopping 108 degrees.
At La Costa Taqueria in Brentwood, with a temperature outside of 108 degrees, grilling is grueling.
Normally on a Saturday, there would be a line into the parking lot. Even though the restaurant fired up its mist machines, only few customers came in.
“With the heat everybody’s home right now,” said Jose Alberto manager of La Costa restaurant.
Saturdays are also usually one of the busiest days of the week at Harry’s Wine Depot and Tavern, this Saturday, the patio was empty and the tavern’s live entertainment cancelled because of the heat.
As the mercury rises, profits are dropping.
“It’s terrible it’s really bad usually on a Saturday we make several thousands of dollars and today we just had a couple hundred,” said Tammy Zickuhr, owner of Harry’s Wine Depot and Tavern.
Because of the heat, the tavern only had six customers all day. Instead of closing at 11 p.m. Saturday, they shut their doors for the day by 8 p.m.
Bilal Johnson and his son Leo were among the few people who ventured outside in downtown Brentwood Saturday, sweating through a bike ride.
“I would describe the heat as suffocating,” Bilal Johnson said.
But some managed to find relief from the scorching sun. Two people in Brentwood waged an epic water battle against each other a war where getting drenched is a victory.
According to Meteorologist Rob Mayeda, heat advisories and excessive heat warnings will continue through Sunday night.
