The company said in a one-paragraph summary filed Thursday with state utility regulators that it had experienced an outage on the line about 15 minutes before the fire started. The company said it later observed damage to a transmission tower on the line near the town of Paradise.

The fire has killed at least six people and destroyed hundreds of homes. Paradise is 180 miles northeast of San Francisco.

The filing was first reported by KQED News.

Fire officials have not determined a cause for the blaze.
