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

Southern California Edison, a unit of utility Edison International , said on Monday preliminary analysis of data showed a "momentary and expected increase in current" on its energized lines in the Eaton Canyon corridor on Jan.

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.

Southern California Edison (SCE), a subsidiary of Edison International, said on Thursday that it was probing whether its equipment was associated with the ignition of two Los Angeles-area wildfires this year.
