In terms of a plant demonstratively making power yes, but in terms of being a substantial part of the grid not as much. Also, I don't think general fusions plant is practical, too extreme mechanically.

I feel the Tokamak's are going to the workhorses, but as we gain more access to the moon they will have more applications. Tokamak's that burn a tritium-deuterium fuel will need to be heavily shielded because they produce high energy neutrons and because they require a thermal cycle to make power. So even if the reactor itself isn't too large, the shielding and generating equipment will be.

When we have more moon access, a permanent presence and some industry there and can mine helium-3, then a whole new generation of reactors and applications will become practical because the resulting products are all charged particles which means they can produce electricity directly without thermal conversion and heavy shielding will not be required making much smaller reactors possible and applications like fusion powered flight, space craft, trucks, trains, etc, feasible.

One aspect of fusion, verses fission, because you don't have the danger of meltdowns, explosions, and radioactive waste you can site these things at the load, in the middle of a big city, etc.
