California's biggest problem is that they basically have gov run power utilities with how they regulate them. Price controls, complete oversight... and yet when there are issues the politicians and bureaucrats get zero blame. The government is so stupid that they have been trying to decommission Diablo Canyon Power Plant for years, their largest power plant which just happens to be nuclear. Most of the plants are natural gas and produce significantly less power. The state has focused on so called renewables which produce a minuscule amount compared to the two nuclear plants in the state.

As a consequence of these poor management decisions the power companies must import power from other states and pass that increased price along to consumers. Mind you, I mentioned price controls. This is one reason why PG&E for so long did a poor job of maintaining their infrastructure. They were forced to keep prices below market rates. Since the massive fires of a few years ago the commission allowed them to raise their rates over the next ten years and the prices are insane.

I think people have started to realize that they can't decommission the nuclear plant. Last I heard it was delayed again due to the dependence on its power. The whole thing is so absurd and an example of the failure of central planning.
