I blame the CPUC for basically everything regarding the crappiness of being a grid customer in California. PG&E is exactly the result you'd expect to get in our regulatory environment.
Our regulators rubber stamp every tariff plan the company puts forth, and lets them get a larger profit margin on capex vs opex. So of course the optimal strategy is to run all equipment to failure and replace it with maximally expensive everything as frequently as possible.
At that price of 37.4 cente per kWh and up I'm quite serious when I say that if I suddenly found myself owning a California house, I'd buy enough solar to meet my load needs, install a shitload of telecom grade 4000 cycle rated lifepo4 batteries (4.9kWh is about $1700 per module), charging setup, inverters etc and go off grid.
Maybe keep the grid link attached to a meter and 100A panel hooked up to nothing if needed for municipal compliance reasons.
That's pretty much what I'm doing, and for that reason.
I don't have a great explanation for why it isn't happening faster, but I predict a substantial exodus from the California grid. Especially so in places with gas bans or among folks who electrify of their own accord.
