Cal Fire released its findings on 12 more Northern California fires that started last October, implicating PG&E in all but one of the fires.
The one fire that was not attributed to PG&E was caused by a power line, although state fire regulators did not say who owned the line.
In response to Cal Fire's findings, PG&E released a statement pointing out a "new normal" and calling on Californians to "meet the challenge of climate change."
In addition to investigating these 12 fires, Cal Fire has also investigated four others, determining all four of those fires were caused by PG&E equipment.
