LOS ANGELES (AP) — Miscommunication led utilities to mistakenly cut power to customers in several California cities during unprecedented demand on energy supplies, operators of the state’s electricity grid acknowledged Wednesday while warning the continuing extreme heat could prompt much larger rolling outages.

Confusion occurred Tuesday afternoon between several Northern California utilities and the California Independent System Operator as the grid was perilously close to running out of energy amid record-breaking temperatures, said Elliot Mainzer, president and CEO of Cal-ISO.

"That is certainly concerning to me," Mainzer said, adding that he was looking into what happened and how many customers were affected. “There was a lot happening on the grid for everybody last night. And so we’ll we’ll double down on the communication to make sure that doesn’t happen again.”

With record demand on power supplies across the West, California snapped its record energy use around 5 p.m. with 52,061 megawatts, far above the previous high of 50,270 megawatts set July 24, 2006.

As residents and businesses cranked air-conditioning to escape withering heat across the West and solar power supplies began to wane, Cal-ISO issued a stage 3 alert to prepare utilities to initiate outages if demand didn't decrease. The state’s legal marijuana regulatory agency urged businesses to turn off lights and reduce power or use backup generators.

With the state on the brink of outages, Gov. Gavin Newsom for the first time triggered a wireless emergency alert system at 5:45 p.m. that sent messages to 27 million cellphones urging them to turn off or reduce non-essential power.

Within moments, there was a reduction of more than 2,000 megawatts, bringing the state “back from the edge,” Mainzer said.

“It took a very loud signal," Mainzer said. “I think they now recognize that we’re not messing around. This is a real issue. And we need real response.”

Newsom, speaking in Beverly Hills, said he had debated pushing that button for the past four to five days. He ultimately decided to test it and concluded it was a game changer, though he's reluctant to use it too often because he fears weakening its effectiveness.

With residents and businesses under the eighth consecutive day of a “flex alert” requesting power conservation between 4 p.m. and 9 p.m., a similar response was needed Wednesday.

Western states are struggling through one of the hottest and longest September heat waves on record. Temperatures began soaring last week and the National Weather Service warned that dangerous heat could continue through Friday, despite some slight moderation.

California’s state capital of Sacramento hit an all-time high Tuesday of 116 degrees (46.7 C), breaking a 97-year-old record.

In state office buildings, thermostats were being set at 85 degrees (29 C) at 5 p.m. to conserve electricity.

Six places in the San Francisco Bay Area and central coast set all-time record maximum temperatures, including Santa Rosa in Sonoma County's wine country.

Salt Lake City and Reno, Nevada, broke records for the hottest temperatures ever recorded in September, according to the National Weather Service.

Scientists say climate change has made the West warmer and drier over the last three decades and will continue to make weather more extreme and wildfires more frequent and destructive. In the last five years, California has experienced the largest and most destructive fires in state history.

The latest wave of high temperatures has surpassed anything the state has seen, including a heat snap in August 2020 that led to two days of rotating power outages, Newsom said.

“We threw out all the old playbooks in terms of our scheduling (for) worst case scenarios,” Newsom said. “Even the worst of the worst case scenario never extended for a week like this."
