In newly filed court documents this week, PG&E has again pressed its case that private power equipment outside of Calistoga may have caused the Tubbs fire, the most destructive and deadly of the 2017 North Bay wildfires.
The filing builds on an explanation PG&E first offered last year for the cause of the Tubbs fire, naming the landowner of the utility suspects responsible for causing the blaze and singling out a caretaker who PG&E said was not licensed for electrical work done on the property, including repairs to a power pole about eight months before the fire.
The new details, made public in a court filing Monday, are included in a PG&E report that outlines the utility’s investigation into 22 major Northern California wildfires from October two years ago.
State investigators remain at work on their report into the cause of the Tubbs fire, which killed 22 people and destroyed more than 5,600 structures in Sonoma and Napa counties, most of them homes.
