If someone takes it near the power plant, and all the infrastructure is there for it. You don't build a (large) nuclear power plant just for these customers though. Generally, with a high amount of renewable but fluctuating supply, we have to get away from the base load model, towards a residual load model.
The burden of buffering the fluctuation is on those creating the fluctuation, not on those not doing so.
Says who? We can design the markets like that if we want to, but that won't help us reach our climate targets.
