Spain has 3x the emissions intensity of France. The Nordics (some of them) have energy that is cheap and clean like France. That's because they have base load that doesn't emit CO2 like France.

And the germanics have higher price than France, which can benefit from importing cheap spanish power (when not in outage) and reselling it at 5x to germanic countries.

Spain has better weather, more hydro, cheap African gas and still nuclear. And emissions are worse

And the French cannot seem to replicate the putatively low price they paid for their first nuclear rollout.
