Does that comparison make sense? You're comparing investments into the national grid with energy prices set by international trade. Power is imported and exported all the time, and the lack of affordable fossil fuels abroad will put pressure on cheaper local prices.
I don't think going nuclear would've made a difference here. Someone is making a lot of money selling power locally for prices that only make sense in an international context. Whether that's done by wind farm operators or nuclear plants, the result will still be the same.
