The utility has noted multiple irregularities, but maintains there is no evidence its equipment sparked the destructive Eaton fire.

Southern California Edison said video evidence had led it to look more broadly at whether its equipment might have been the cause of the deadly blaze.

Edison International’s utility said it is looking at whether a decommissioned power line started the Eaton wildfire as part of a probe into the cause of the blaze that razed more than 9,000 structures near Los Angeles.

In a Jan. 27 letter to the regulators, Southern California Edison revealed new details regarding its electrical equipment before the Eaton Fire.
