SACRAMENTO, Calif — After nearly four days without electricity, PG&E has restored power to 100% of their customers impacted by the Public Safety Power Shutoff.

PG&E set a goal of having power restored to impacted customers by the end of Saturday and were able to reach it around 6 p.m. Saturday. The Public Safety Power Shutoff impacted about 738,000 customers.

The last group of counties to see power restored were Amador and Calaveras counties.

PG&E said it found 50 instances of damage to its power lines. An additional 100 instances are being investigated, and PG&E Vice President of Asset and Risk Management Sumeet Singh said each of these had the potential to cause a wildfire. 

He could not say if this damage mirrors what could be found during a typical "Indian summer" windstorm. 

During the news conference, PG&E CEO Bill Johnson defended his company's decision to shut off power, and said the risk of wildland fires was not keeping pace with government regulation for utility companies. 

"We recognize that PG&E has given little reason in recent years to trust us," he said. "Much of that lack of trust comes from events where PG&E did not keep people safe. As we endeavor to keep you all safe, and, live up to that commitment I just made, we want to earn back your trust." 

Johnson said Saturday afternoon's press briefing would be the last during this specific event.
