California has massive penetration of distributed solar to the point that solar supply exceeds total grid demand much of the time, making the marginal value of additional solar generation very low. Which is a pretty big difference when comparing viability of utility solar installations in California to anywhere else in the country. And I assume the particular California plant you are talking about is the big solar thermal/natural gas hybrid plant that was being built just as the big price drop in photovoltaics essentially made it obsolete, which barring unexpected breakthroughs on some competing technology, is a big difference from any not-already-obsolete system being considered now.
