(CNN) - California's Pacific Gas and Electric power company is responsible for the devastating 2018 Camp Fire — a blaze that killed 85 people and destroyed thousands of structures — according to investigators with the California Department of Forestry and Fire Protection.
CAL Fire said in a news release on Wednesday that electrical lines owned and operated by PG&E started the fire early November 8.
"The tinder dry vegetation and Red Flag conditions consisting of strong winds, low humidity and warm temperatures promoted this fire and caused extreme rates of spread, rapidly burning" through parts of California, CAL Fire said.
PG&E did not immediately respond to a request for comment. However, in April the company said it was "probable" that its equipment started the Camp Fire.
The power company has been in a state of transition for most of the year. It filed for bankruptcy in January as it came under pressure from billions of dollars in claims tied to deadly wildfires.
Last month, PG&E named William Johnson — previously the CEO of the Tennessee Valley Authority — as its CEO. It also appointed 10 new members to its board of directors, while seven members stepped down.
