SAN FRANCISCO — California’s power grid operator pleaded for more energy conversation to overcome another large energy gap Tuesday and avoid rolling blackouts as Gov. Gavin Newsom declared an emergency over hundreds of wildfires burning throughout the state.
Steve Berberich, president and CEO of the California Independent System Operator, praised residents and businesses for astonishing conservation efforts that kept the power on Monday night.
He said operators were stunned by the “dramatic flattening” of consumption at 3 p.m. Monday after his office warned that as many as 3.3 million homes and businesses would be affected by rotating, two-hour outages. The order never was issued and the warning was canceled.
“It was stunning the conservation response that we got,” he said Tuesday. “I know it’s hot and I know it’s hard, but those same actions today can make all the difference in the world.”
The state is in a days-long heatwave that has stressed the electrical system and resulted in rolling blackouts over two nights last weekend. The strong ridge of high pressure responsible for the heat wave was expected to weaken, but excessive hot weather was forecast for the weekend as families stay at home because of the coronavirus pandemic.
Newsom declared a statewide emergency Tuesday, saying the extreme heat and lightning has sparked hundreds of wildfires. “We are deploying every resource available to keep communities safe as California battles fires across the state during these extreme conditions,” he said.
Evacuations were in effect or growing in the Napa County wine country north of San Francisco Bay, near Salinas in Monterey County, around Oroville Dam north of Sacramento and near the Nevada state line north of Lake Tahoe.
A fire in Napa County was burning close to remote grape-growing properties owned by Villa Del Lago Winery.
“Our vineyard workers had to evacuate very quickly. And we heard this morning that there was zero containment, so that’s scary. It’s very steep, so I know it’s hard for firefighters to get up there,” said Dawn Phillips, who works in customer service for the winery.
In Southern California, evacuations continued for a week-old fire in the mountains of northern Los Angeles County. Dynamic weather churned up thunderstorms bringing the double threat of more lightning-sparked fires and flash floods.
California ISO issued the first rolling blackouts in nearly 20 years on Friday, resulting in the state’s three biggest utilities — Pacific Gas & Electric, Southern California Edison and San Diego Gas & Electric — turning off power to more than 410,000 homes and businesses for about an hour at a time until the emergency declaration ended 3 1/2 hours later.
A second but shorter outage hit Saturday evening, affecting more than 200,000 customers.
Former Gov. Jerry Brown called the rolling blackouts “a kerfuffle, not a crisis,” adding that California’s bigger challenge will be boosting its renewable energy sources to handle the increased demand for electricity that will come due to climate change.
Berberich credited large power users, businesses and residential customers for their good work. He said the state may be short 2,700 megawatts around 7 p.m. Tuesday, which is smaller than the 4,400-megawatt shortage projected for Monday. The shortage of 4,400 megawatts equates to about 3.3 million homes and businesses.
Newsom signed a different emergency proclamation Sunday allowing some energy users and utilities to tap backup energy sources, which helped with Tuesday’s energy needs. He also demanded an investigation into Friday and Saturday blackouts.
Scorching weather has hit other Western states, making it harder for California to import extra power.
