The nuke plant can charge you double... except if you can import power. At that point, the problem nuclear runs into is that coal/gas is more adapted to fluctuating demand. So nuclear has to face excess production from wind/solar exported by e.g. Germany at times, and can't make up for it when wind/sun is offline, because the germans then adapt with gas. That is kind of a bad situation if you optimize for co2. Also power walls are not a scalable solution. The raw ressource just isn't there for it to happen.
