PG&E's prices are not a function of what people will pay though, it's a function of what people expect.
CA wants green energy now (aggressive targets), needs to have fire hardened infrastructure (expensive upgrades), and wants full service to sprawling remote areas using modern infrastructure.
The combination of these is incredibly expensive.
If you don't believe me, buy PGE stock and get your dividend from their "greed". But honestly, the stock is an awful performer, because the actual problems facing them are real.
