While that's an interesting proposition, that could at most reduce our rates by their profit rate, which is not nearly enough.
We need systematic changes to fundamentally lower costs to more reasonable rates, like what other smaller municipal utilities deliver in California, which are 1/3-1/2 the cost.
The problem is not profit, but how profit is established. PG&E takes a fixed rate of profit of the total cost, so they are incentivized to make everything as expensive as possible. This is in contrast to most market based systems, where a new competitor with lower costs gets to directly take the lowered cost as profit. We instead use regulatory boards, Public Utility Commissions, to determine which investments utilities can make and what prices they can charge customers. This is highly regulated, but the outcomes have been terrible. Even Arizona, whose equivalent of the PUC has been disastrously corrupt, or places like Ohio, which has sent state legislators to prison for their corruption on utility matters, have far lower rates than we do in California.
We have bad regulation in California. That's the fundamental problem. Gavin Newsom, and all the governors who came before, have failed us on our electrical grid. That said, clearly high electricity prices are not a huge problem for our economy, and the high cost of living from high housing costs is clearly a driver of expense for everything a utility does, but we fundamentally have not had the right controls on the grid to keep costs reasonable. We have not set up a system where PG&E profits from delivering lowered costs. Our regulation prevents us from achieving what Marx calls the "falling rate of profit" as we would usually see with a market. Something must change, but simply eliminating PG&E profits won't do it, it's not enough.
