Electricity customers frustrated by the recent round of PG&E Public Safety Power Shutoffs may want to brace for another round as soon as this week, the utility has warned.

Pacific Gas and Electric Co. has activated its Emergency Operations Center in San Francisco to monitor a potentially strong and dry offshore wind event that could impact portions of the North Bay, Sacramento Valley and the Sierra Foothills on Wednesday and Thursday, Oct. 23-24.

Due to those forecast weather conditions, combined with existing dry fuels, PG&E is considering implementing a Public Safety Power Shutoff across portions of those 17 counties. Although no power shutoff was called immediately, but PG&E said it will provide updates on that front several times a day for the next few days.

The status of PG&E’s seven-day PSPS Potential Forecast has moved to “PSPS Watch,” indicating that there is a “reasonable chance of executing a PSPS to reduce public safety risk in a given geographic zone due to a combination of adverse weather and dry fuel conditions.”

The counties that could be affected include Marin, Solano, Sonoma, Napa, Amador, Butte, Colusa, El Dorado, Lake, Mendocino, Nevada, Placer, Plumas, San Joaquin, Tehama, Yolo and Yuba.

PG&E said its meteorological and operations teams are monitoring the weather system that could impact portions of the Sierra Foothills and the North Bay, across portions of the 17 counties. The main wind event is expected to last about 18 to 24 hours, from Wednesday evening through mid-day Thursday.

Any potential power shutoff associated with this coming week’s wind event is expected to be significantly smaller, with lesser impacts, than the Oct. 9-12 power shutoff that left thousands of Bay Area energy customers in the dark.
