The cause of the blaze, which was 60 percent contained on Sunday, is under investigation. In a previous regulatory report, PG&E, which operates in the northern part of California, said it experienced an outage on a transmission line on the morning of Nov. 8 near the town of Pulga, near where the fire is thought to have started.
Authorities were still searching for signs of the 1,276 people listed as missing after the Camp Fire tore through the mountain town of Paradise. The remains of 76 people have been recovered so far in what is considered the state's deadliest-ever wildfire.
A CPUC spokesman confirmed that the agency received the second report on Friday, and said the incident would be incorporated into its investigation "to assess the compliance of electric facilities with applicable rules and regulations in fire impacted areas."
Investors are watching for clues about whether California's government will step in to save PG&E should it eventually be found responsible for the fire and should any potential liability exceed the utility's resources.
CPUC President Michael Picker told Reuters on Friday that utilities must be able to borrow money cheaply in order to properly serve ratepayers. Similar comments from Picker a day earlier caused PG&E's stock to surge in after-hours trading.
The company's stock had slumped more than 60 percent since the wildfire broke out, on fears that without help from California's government, the utility could go bankrupt should it eventually be found responsible.
