French generation is ~70% nuclear (10% wind/solar) and German is ~10% (~40% wind/solar). Yet their prices track each other closely. So I think this explanation is too simplistic.
Possibly there are large interconnects between the French and German grids levelling out wholesale prices, but my assumption is that they cannot carry enough power for this imagined scenario where nuclear makes a big difference.
