There are fundamental reasons why fusion, at least the DT variety, will be more expensive than fission. It has to do with inherently low volumetric power density of DT fusion reactors. ITER is 400x worse than a PWR; ARC is 40x worse. So, the reactor itself becomes much larger and, because it's also more complex, much much more expensive. The other putative advantages of fusion cannot make up for this. And fission itself is too expensive, so DT fusion loses to a loser. It's a double loser. If you want to see where energy will come from in a deregulated environment, look at Texas. New grid capacity there is solar and batteries. Even gas isn't being installed much; the Texas state government put down $7.2B to fund more gas capacity yet this money has been mostly spurned, I think < $400M has been taken. New nuclear is completely out of the picture there.
