The economic viability of a fossil fuel plant that's only used 4 months out of the year.

If the plant shuts down because it's no longer economically viable/doesn't cover operating costs, what happens next winter?

Ostensibly it gets replaced by a grid storage array and sufficient renewable inputs.
