> Why not build the plant in LA? Is it more efficient to ship electricity instead of gas; or is it just more politically convenient to pollute Utah instead of LA?

Great question. It is easier to rely on existing transmission at Intermountain than it is to build a gas turbine in LA (along with whatever infra is needed to provide a reliable supply of fossil gas to the generator site). You can even add batteries, solar, wind etc in the future at that site; coal sites are being remediated and turned into battery storage colo in many situations to rely on that existing transmission infra.

(consider the fungibility of electricity vs other energy mediums)

I read somewhere that old coal plants would in theory be trivial to drop-in upgrade to nuclear: you just need to replace the heat source with a nuclear one, but the rest of the infrastructure can continue to be used.

The problem is that coal plants are sprinkled with a whole bunch of radioactive fly ash, and normal radiation level for a coal plant would violate the hell out of regulations for a nuclear plant.
