Like fwir said, it’s difficult to determine what regulations are and aren’t needed. But one example: in the U.S., automatic load following equipment for nuclear power plants are prohibited, so load following needs to be done manually. Whereas in France, this equipment is allowed, and very important, given nuclear makes up a much larger proportion of their grid (and tends to load follow more).
