That’s not a lot of generating capacity. A large coal or nuclear plant is typically about 1,000 megawatts. A large single unit gas fired combustion turbine will produce 200+ megawatts.
I currently have a single 1.3GW (yes that's "G" as in Gigawatt) generator rotor from a California nuke plant in my shop in Virginia for a complete rewind, and dynamic testing . The plant has two units the same size. I had their spare rotor in the shop a year and a half ago, and the other unit several years ago when So Cal Edison had a grid shortfall and was doing rolling "brown-outs". We had half their needed generating capacity sitting on a lathe here in Richmond.
$200 is the base cost to fund the plant’s construction. The actually costs passed on to the consumer each month will be significantly higher then that
A solar plant with fixed panels can produce 100% power only one hour a day (during local apparent noon), and can effectively produce usable (80+ maximum) power only from 10:00 (AM) to 14:00 (PM) in the 3 winter months, and from 09:00 to 15:00 during the hottest 3 summer months.
At least - in the desert, and at that relatively far south latitude, and with that little pollen and rainfall, only dust will cause further efficiency losses. Then again, central southern AZ is a long way from a huge power demand as well.
Again, putting up this much money for a (heavily-taxpayer-subsidized) solar plant is merely a political stunt.
