PG&E crews found damage to electrical equipment during pre-emptive power outages in Northern California earlier this month, according to a report sent to utility regulators on Friday.
PG&E cut power on June 8-9 to roughly 1,600 customers in areas around Lake Berryessa, northeast of Napa, and some 20,000 customers in or near the area devastated by last November's Camp Fire.
The public safety power shutoff was intended to reduce the risk of wildfires during a period of high winds, hot temperatures and low humidity. Most of the outages lasted from 12 to 18 hours, with the utility restoring power to customers after fire risk subsided and crews inspected equipment for damage.
The pre-emptive shutoffs were the first of 2019 and are part of PG&E's new state-mandated wildfire mitigation plan.
Friday's outage report was required by the California Public Utilities Commission and provides a detailed look at PG&E's reasoning for the shutoffs and how the utility communicated with customers and local officials about the event.
