France shows, how much effort it takes to generate a stable grid with electricity being produced mostly by nuclear power plants. Due to the limitations in regulating the power output, they have to operate the power plants not at the most efficient load but a lower one which gives them more regulation capability. Also, using up the electricity at night becomes a challenge. Belgium for example installed huge streetlights on their highways so they can increase the night load.
