SACRAMENTO, Calif. (AP) – California’s chief utility regulators and a Pacific Gas & Electric executive are testifying that the utility is behind on installing devices meant to ease the severity of power shut-offs during potential wildfires. They also said the utility hasn’t yet hired and trained emergency response specialists in each county. The testimony came during a hearing Thursday of the California Senate’s committee on utilities. It’s the latest setback for the bankrupt utility as it tries to modernize its infrastructure that has been blamed for causing deadly wildfires that killed more than 100 people in 2017 and 2018.
