SAN FRANCISCO (CBS SF) — With red flag warning conditions packing howling winds predicted for late Saturday, Pacific Gas & Electric officials went forward with the second planned power shutoff this week because of mounting fire danger conditions from the Bay Area to the Sierra.
Pacific Gas & Electric said the blackouts began around 2 p.m. Saturday in parts of 36 counties. About 940,000 customers — more than 2 million people — will be affected.READ MORE: Lockdown-Violating Underground Gatherings Investigated Over Recent Spate of San Jose Shootings

The utility referred to a “historic wind event” in a Friday news release, stating that models “indicate the weather event could be the most powerful in California in decades, with widespread dry Northeast winds between 45-60 miles per hour and peak gusts of 60-70 mph in the higher elevations.”

The utility said the outages were needed because of the threat of destructive and deadly wildfires. Currently, firefighters were battling a 25,000-acre plus wildfire near Geyserville that has destroyed 77 structures, forced thousands to evacuate and may have been sparked by PG&E transmission lines during a red flag warning event Wednesday night.
“We are preparing for what is likely going to be a widespread safety shutoff across our service territory to combat the risk of a catastrophic wildfire,” said PG&E executive Sumeet Singh.
PG&E officials said they’ve learned from this week’s outage after admitting they only shut off low-voltage lines and not high-voltage transmission lines prior to the Kincade Fire because winds weren’t strong enough.
“We have revisted and adjusted some of our standards and protocols to determining when we will deenergize a high voltage transmission line,” said PG&E president Andy Vesey.
He said if power lines are in areas with higher winds than forecast because of topography — for example, ridges that act as wind tunnels — those lines will likely now be shut off.
The outages may be widespread and so is anger and frustration among customers.

“One of the things that we’re committed to do as soon as we get through fire season and we can sit back is to really think about what additional sectionalizes we need to put in, how we might be able to reconfigure the system, so that areas that don’t typically see bad weather but are somehow connected through the system will not be impacted,” Vesey said.
