Storage is not there generically for seasonal power demand. But it's used in national grids for balancing, and short demand distribution already out competing the previous gold standard of natural gas peaking plants. The costs are dropping following a fairly predictable volume manufacturing expansion curve - and that ramp up is much more viable than the very specialized logistics support needed for expanded nuclear plant construction. While I'm very skeptical of fossil fuels with carbon capture being any sort of all-around solution, for seasonal use - nat gas storage with fuel cells or turbines with carbon captured outputs seem like a possible mid-line seasonal solution.
