SDG&E has an emergency center to monitor fire weather conditions around the clock using 220 weather stations with real-time data on wind, temperatures and humidity conditions, SDG&E said.
The state of California gives utility companies the ability to temporarily turn off power to specific areas to reduce the risk of wilfires caused by electric infrastructure.
According to the state, electric infrastructure has been responsible for less than 10% of reported wildfires but those attributed to power lines consist of about half of California’s most destructive fires.
“Weather conditions change, and we have our team of professionals watching closely. However, we wanted to let our customers know as early as possible that they could be impacted so they can make alternate holiday arrangements if needed,” SDG&E chief safety officer Kevin Geraghty said in a written statement.
“Once conditions come back to normal, they will have people walk the lines … physically looking and using drones to make sure nothing has blown into a power line before they turn it back on,” said SDG&E spokesperson Denice Menard.
