In the era of solar power saturating the grid in daytime, the energy cost is far less of an issue - At least, I assume California has similar characteristics to Australia in this regard.

California is richest state in USA, it's is richer than many countries, it can afford such cost. Florida has more than double the desalination plants than California, and it is poorer than California.
