SAN FRANCISCO (KGO) — Amid the extreme heat, PG&E is warning customers of a Public Safety Power Shutoff (PSPS) that could impact 172,000 customers in 22 California counties, including some in the Bay Area.

The warning for power outages are due to a forecast of an “offshore dry wind event,” the utility said Sunday morning. Residents in more than 20 counties were warned on Sunday and the agency says the potential PSPS event would not go into effect until Monday evening at 9 p.m.

Napa and Sonoma counties are included on both Monday and Tuesday because the areas are further subdivided in each region, PG&E officials say. The two counties include 23,000 customers and the utility intends to begin deenergization at 3 a.m.

PG&E’s in-house meteorologists, as well as its Wildfire Safety Operation Center and Emergency Operations Center, continue to monitor conditions closely and additional customer notifications will be shared.

Scott Strenfel, Meteorology Operations with PG&E says the “potentially severe weather event” will feature up to 20 to 30 mph winds with gusts up to 50 mph. The wind conditions during the heat wave pose potential fire danger.

Here's the timeline when PG&E plans to turn off power for each county on Sept. 7-9, 2020.

Customers can look up their address online to find out if their location is being monitored for the potential safety shutoff here.

PG&E says customers will be notified approximately 48 hours, 24 hours and prior to the potential shutoff. Officials say 48 hours is a “reasonal confidence” to give the footprint of a possible power shutoff.

47 Community Resource Centers will be open across 17 counties starting on Tuesday. The centers will be open from 8 a.m. to 10 p.m. and reflect COVID-19 heath guidelies. Customers can go to the center for device charging, up to date information and water and snacks. Find a center near you here.

VIDEO: What is a Flex Alert?

The PSPS follows a statewide Flex Alert amid heat wave, asking Californians to conserve power in an effort to avoid rolling blackouts over Labor Day weekend.

The Flex Alert is in effect Saturday through Monday, from 3 p.m. to 9 p.m. each day.

With record-high temperatures between 95 and 110 degrees around the Bay Area – and even hotter elsewhere in the state – there’s expected to be a greater demand for power, with everyone staying indoors and blasting the AC. Overnight temperatures are also supposed to be about 10 degrees higher than normal, according to California ISO, which doesn’t allow infrastructure the time it needs to fully cool down.

Governor Gavin Newsom even signed an emergency proclamation to free up additional energy capacity amid extreme temperatures across California. The proclamation permits power plants to generate more power by suspending certain permitting requirements, helping to alleviate the heat-induced demands on the state’s energy grid.

That’s why state officials and utility companies like PG&E are asking people to reduce energy use whenever possible during the peak afternoon and evening hours. If the projected power use exceeds the state’s power grid, PG&E may be forced to shut off power to neighborhoods using rolling blackouts, as was deemed necessary in the heat wave we saw in early August.

“As of Thursday morning, CAISO has given no indication of a need for rotating outages like those experienced by Californians last month,” said PG&E in a press release. That being said, heat-related power outages could still occur if equipment gets overheated, a spokesperson told ABC7 News.

PG&E spokesperson Deanna Contreras told ABC7 the focus right now is on conservation.

“Every little bit from 3 p.m. to 9 p.m. will help reduce the chances of CALISO preparing for those rolling outages,” said Contreras.

California ISO is asking people to reduce energy consumption by:

  • Setting the thermostat to 78 degrees
  • Turning off unnecessary lights
  • Using large appliances like washers and dryers during off-peak hours
  • Close blinds and drapes to keep rooms cool
  • “Pre-cool” homes overnight so they don’t need as much energy to cool during the day
  • Use fans instead of AC when possible
