LOS ANGELES (CNS)—The holiday heat wave is taking a toll on the Southern California power grid with more than 90,000 Southern California Edison and LA Department of Water and Power customers without power early Sept. 7 and electricity for some not expected to be restored until Sept. 8.

The DWP reported at 9 p.m. Sept. 6 that its crews had restored power to 77,000 customers since the extreme heat storm started causing problems on Sept. 5. But crews were working to restore power to some 70,000 customers by repairing overheated and overloaded distribution equipment.

Neighborhoods most affected by the power outages included Highland Park with 12,000 customers, Mid-Wilshire with 5,100, Sylmar with 4,500, and Studio City with 3,700. The DWP warned some customers might be without electricity for 24 to 48 hours.

By early Monday, Edison reported 402 outages on its website affecting 19,091 Los Angeles County customers, and 95 outages in Orange County affecting 4,055 customers.

There were 2,289 customers without power in unincorporated Los Angeles County, 1,690 in San Gabriel, 1,194 in South Gate, 1,075 in Whittier, and 710 in Pomona.

Newport Beach had the greatest number of Orange County outages with 636 customers affected, Mission Viejo had 194 and Lake Forest had 180. Edison said some customers might not have their power restored until Tuesday.

The DWP urged people to set air conditioners to 78-82 degrees and “skip laundry and heavy appliance use.

Those experiencing a power outage were urged to report it at www.ladwp.com/outages or by calling 1-800-DIAL-DWP (1-800-342-5397) using the automated system.

Meanwhile, Gov. Gavin Newsom highlighted a number of steps to free up energy capacity.

“California has always been the canary in the coal mine for climate change, and this weekend’s events only underscore that reality,” Newsom said. “Wildfires have caused system failures, while near record energy demand is predicted as a multi-state heat wave hits the West Coast for the second time in a matter of weeks.

“Californians are rising to the occasion to meet these unprecedented challenges for our energy grid, and I want to thank all of the businesses and individuals who are conserving energy. Californians should heed (California Independent System Operator’s) warnings and flex their power to shift energy consumption to earlier in the day.”

Newsom said the state has already taken the following actions to free up capacity:

-Working with large commercial and public energy consumers to shift their energy usage away from peak hours;

-Ramping up appeals to Californians to flex their power, pre-cool their homes before noon and conserve energy from 3 p.m. onward;

-Partnering with third party energy producers to bring back-up energy generation resources online, from the State Water Project to DWP and the state’s investor-owned utilities;

-Asking the Navy and commercial ports to use on-ship electrical generation instead of pulling resources away from the grid.

At about 6 p.m. Sept. 6, the California Independent System Operator, which oversees the state’s bulk electric power system and it utility companies, declared a Stage 2 Emergency, announcing its operators were “taking all the steps to protect the grid, manage transmission loss and avoid outages.”

A Stage 2 Emergency means “the CA ISO has taken all mitigating actions and is no longer able to provide its expected energy requirements. A Stage 2 warning requires ISO intervention in the market, such as ordering power plants online,” according to the agency’s website.

The Stage 2 Emergency was lifted just after 9 p.m. However, the flex alert will continue Sept. 7 from 3 p.m. through 9 p.m.

Temperatures set new records around Southern California Sept. 6, including 121 degrees at Pierce College in Woodland Hills, which broke a 2006 record of 119; Van Nuys hit 118 degrees, breaking a record of 117 set in 2018; and the high of 114 degrees at Burbank Airport tied a previous record set Sept. 5.

An excessive heat warning issued by the National Weather Service will be in effect until 8 p.m. Sept. 7 in the San Gabriel and Santa Monica mountains, Santa Catalina Island and the San Fernando, Santa Clarita, San Gabriel and Antelope valleys as well as Orange County.

Cooling centers will be open throughout the weekend in Los Angeles and Orange counties. The list can be found at https://ready.lacounty.gov/heat/ and www.211oc.org/resource-centers/extreme-heat-cooling-centers.
