Well, California has some of the highest electricity rates in the US. IIRC the exceptions are Hawaii and Alaska.
That being said, last I looked, it was more like $0.21/kWh. Hadn't realized that it had gotten that high.
EDIT: Here's a per-state list for average residential prices for 2024:

That has California at an average of 29.49 cents/kWh, which is quite high as the US goes, but not nearly as high as yours. It does say that prices went up 11% since last year.
California has had a major problem where billing just happened per kWh, so that people who were using solar (or some other form of local generation) were basically dumping the cost of maintaining the grid connections onto people who weren't doing local generation, since the solar users were purchasing few kWhs. This was very politically controversial, especially since the latter group was generally poorer. IIRC, California is just or will be passing policy changes that will limit that, so the kWh cost from the grid should drop, though people getting most of their power from solar will have a higher overall bill than they had; there's a separate bill item for the grid connection and for the electricity provided over it.

Not sure when that enters or entered into force. However, it should depress per-kWh charges, though there'll be a fixed charge for the grid connection.
