Sorry for the bad calculations here, but 43,000 GWh/y means 4.9GW of new generation (this is assuming a capacity factor of 1), right? I’m just Googling around but I’ve seen capacity factor estimates at around 0.24 for CA utility-scale solar. Rounding, that’s about 20GW worth of name-plate installed utility solar capacity. I’m seeing estimates of $0.89 - $1.35/watt for building that solar. Which puts this cost around $17.8bn-$27bn in construction costs, which genuinely doesn’t seem that bad for a project as big as “electrifying all consumer transportation in a large state”? Obviously people will need to get used to charging their cars during the day, and this won’t be the only new power source.
I’m worried I missed a division and I’m off by a factor of 100x somewhere :)
