Southern California Edison is looking into whether its equipment is tied to the Eaton and Hurst Fires, its parent company said, though the cause has not been officially determined.

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.

The losses from past California wildfires sent one of the nation’s biggest utility companies into bankruptcy. So lawmakers came up with a plan: They created a wildfire fund to act as an insurance policy for utility companies.
