Southern California Edison says its equipment might have started the Silverado Fire.
Chris Abel with Edison tells KNX Edison sent a report about the fire to the California Public Utilities Commission.
"It appears that a lashing wire attached to a telecommunications line may have contacted SC's power line above it, possibly starting the fire," he said.
The purpose of telling the CPUC is so that the agency can conduct its own investigation into the fire and cause.
Edison turned off power yesterday to more than 18,000 customers in LA, Orange and San Bernardino Counties to try to prevent its equipment from starting wildfires.
They're called Public Safety Power Shutoffs.
