I don't think current costs for fusion are useful for modeling, or really anything, because there's nothing there yet. We don't even have prototypes.

But if there is not a clear and speedy path to get fusion to $30/MWh it's not going to make it. Batteries, solar wind, and geothermal are all busy deploying and getting cheaper every month, year, and decade. The grid system possible with 2035's solar and battery tech is going to be completely unimaginable to today's grid ops.
