I can't even imagine what would be involved logistically to replace PG&E state-wide.
It still is. City of SC (silicon valley power) charges $0.13/kWh vs north of $0.4x/kWh from PGE. It's simply impractical to charge EV at home regardless of which plan you pick at PGE, due to aggressive tier limits and the intentionally crippled "EV plan". PGE is legalized robbery.
We squandered the opportunity presented by PG&E's bankruptcy.
After the fires a few years back and PG&E's subsequent bankruptcy, Newsom threatened just that if they couldn't get their act together.
