SACRAMENTO, Calif. — 7:30 p.m. update:

Power is out in Davis for more 12,000 customers, according to PG&E.

Few details surrounding the outage have been released. However, PG&E says the outage is related to the weather. California is currently in the grips of an extreme heat wave.

The outage in Davis started around 5:10 p.m. It’s not known when power will be restored for all customers.

Power outages are impacting customers in communities in Placer and Nevada counties. 

The outages come as the state’s power grid operator warns of possible and imminent rotating outages to lessen strain on the power grid. However, the California Independent System Operator (ISO) has not called for those outages at this time.

According to PG&E, the outages in Nevada and Placer counties are still being investigated. For now, about 2,700 customers are without power in the Foresthill area of Placer County and more than 1,000 are impacted around Penn Valley and Rough and Ready in Nevada County.

The California Independent System Operator (ISO) declared an Energy Emergency Alert 3  and are anticipating a deficiency in supply. Cal ISO is able to order rotating power outages to lower demand and stabilize the system, however, they have not called for the option at this time. 

“Controlled power outages are now imminent or in process according to each utility’s emergency plan,” according to a news release from Cal ISO.

The ISO said customers can expect calls, texts or emails if they order rotating power outages.

The outage was not a result of the potential rolling blackouts other utilities have been warning about.

PG&E officials say they warned about 525,000 California customers to prepare for potential rotating power blackouts.

Though the California Independent System Operator (ISO) has not asked PG&E to carry out rotating blackouts, according to the company. However, more than 1,100 West Sacramento customers have been without power since about 3 p.m.

City officials said around 1,700 total utilities customers are facing blackouts because of extreme heat reaching unprecedented levels.

Initial determinations by PG&E also cite the weather as reason for the outages, and there is currently no estimated time of power restoration for West Sacramento customers.

Police also report signal lights are down in the area of Industrial Boulevard and Enterprise Drive.

Chances for rotating blackouts across California remain high Tuesday as the state’s Independent System Operator (ISO) is expected to declare a level 3 Energy Emergency Alert around 5:30 p.m., which could lead to rotating outages.

The state managed Monday to get through the first of multiple forecasted days of unprecedented heat that threatens the state’s power grid. According to ABC10 Chief Meteorologist Monica Woods, the hottest time of day typically falls between 3 p.m. and 5 p.m.

“A mixed bag of news with our weather pattern – the good news is we start seeing temperatures drop to the 90s by the weekend, and morning lows get back to the 60s. The bad news is we’re going to increase our fire risk as thunderstorms move into the forecast next week,” Woods said.

Statewide Flex Alerts are extended through Friday, and forecasts show peak energy demand at more than 52,000 megawatts—which would set a new record from the previous high of 50,270 megawatts in 2006.

“This is an extraordinary heat event we are experiencing, and the efforts by consumers to lean in and reduce their energy use after 4 p.m. are absolutely essential,” said California ISO president and CEO Elliot Mainzer.

The ISO declared an Energy Emergency Alert 2 for 4 p.m. to 9 p.m., which allows them to tap into emergency demand response programs that provide financial incentives for reducing energy use.

A Flex Alert is set for Tuesday after 4 p.m., according to the California ISO.
