That said, it doesn't make sense to have just a single place for the entire country, as there are multiple grids in the US (primarily East, West, and Texas), and with very long transmission you can get into phase issues.
Concentrating generation made sense when transmission was cheap in comparison.
But one effect of ever cheaper solar is that transmission costs start to dominate generation costs, because transmission is not getting cheaper.
Cheap solar and storage requires rethinking every aspect and all conventional wisdom about the grid. Storage in particular is a massive game changer on a scale that few in the industry understand.
