The answer to that is simple: powerlines, wind, hydro... No idea why people think solar has to be local, wind requires powerlines and nuclear for some reason isn't neither...

Wind is still intermittent. Transmission and hydro expensive. The point still stands that marginal new power will become much more expensive before solar reaches anywhere close to sole source.
Who said anything about solar being single source??? And everything is expensive, the question is wether or not it is profitable. And politics aside, the financials have decided a long time ago on wind, solar and, sadly enough due to criminally underprized CO2 certificates, coal. New NPPs just barely replace capacity going offline, is always late and always above budget. And even if we ignore the net added capacity of new nuclear plants, the gross capacity being built pales in comparison to wind and solar.
Pushing nuclear power, for other than military or political reasons, is riding a dead horse.
