No, it won't, because PG&E doesn't have the money to do this, and the company is already majority-owned by the PG&E Fire Victim Trust after emerging from bankruptcy.

There are no rich shareholders to foist the costs on. No investors are going to pay tens of billions of dollars, more profit than PG&E generated over several decades, to pay for 10% of the electric wires to be buried. If there were any investors on the hook for this, they would simply declare bankruptcy and walk away.

The only option here is that the costs are paid by ratepayers, or taxpayers. There is no other option available.
