State officials confirmed on Tuesday that a tree coming into touch with lines maintained by the Pacific Gas and Electric power provider caused California's second-largest ever wildfire, which charred just under 100,000 acres last year.

The cause of the fire was discovered west of Cresta Dam, according to a notification from the California Department of Forestry and Fire Protection to the Butte County District Attorney's Office.

PG&E  did not respond to a request for comment right away.

On July 13, 2021, the Dixie fire broke out, destroying 1,329 structures and damaging 95 more.

PG&E announced in November that it had received a subpoena from the US attorney's office seeking documents relating to the Dixie Fire, and the Californian utility projected to lose $1.15 billion as a result.

The California Public Utilities Commission voted unanimously in April of last year to tighten oversight of PG&E, citing the utility's failure to perform required tree-trimming work near power lines in areas with the highest risk of wildfires.

In 2017, PG&E's equipment also contributed to a fatal fire in California. That resulted in the deaths of 46 people, the destruction of at least 245,000 acres, and the destruction of 8,900 dwellings.

In the year 2020, the corporation escaped from bankruptcy. After wildfires generated by its equipment in 2017 and 2018 pushed the utility's possible liabilities into the tens of billions of dollars, it sought protection from creditors.
