(Bloomberg) – California's chief utility regulator said the state may never determine whether PG&E Corp.'s electrical equipment played a role in igniting the deadly blazes near San Francisco earlier this month.

Evidence destroyed?

The wildfires, which have killed at least 42 people and destroyed thousands of structures across California's iconic wine country, may have also burned the evidence necessary to find out what caused them, Michael Picker, chairman of the state's Public Utilities Commission, said in an interview Wednesday.

Utility owner PG&E has meanwhile lost more than $6 billion of its market value amid speculation that downed power lines may have contributed to igniting the fires.

"We still don't know whether the fires caused pole or line damage or the poles caused the fires," Picker said while attending a symposium organized by grid manager California Independent System Operator Corp. in Sacramento. "They may never sort it out."

Climate change's role

What is clear, he said, is that the state must consider climate change's role in how severe wildfires have become and enhance its safety programs. His remarks echoed ones made by PG&E's own chief executive officer, Geisha Williams, earlier this week. In an interview with the San Francisco Chronicle, she stressed the need to consider the right climate strategies as opposed to focusing on tree-trimming.
