PG&E reduced further the number of Bay Area customers without power to 43,794 as of early Thursday, according to a company announcement.
This has been the most impactful storm PG&E has seen, in terms of customers out in the Bay Area, since 1995," the company said in a statement. "This is the thirteenth storm event in the past 75 days."
More than half of the total is still in the South Bay, where 22,415 are without power.
Elsewhere those without power include 14,006 customers on the Peninsula, 7,249 in the East Bay, 41 in the North Bay and 83 in San Francisco.
Some neighborhoods in Redwood City contained pockets still without power on Thursday morning, with restoration times estimated between Thursday evening and Friday.
On Tuesday afternoon, after high winds and rain knocked down trees and wires around the region, about 300,000 were without power.
