Reactive power control is also available to enable voltage control of the plant output, even at no load in some cases. The graph below shows that traditional variability of consumption in France can typically increase by 6.5 to 7.5 GW in one hour between 6:00 and 7:00 for a typical winter day, during which generation has to be ramped up accordingly. Other generation plants such as hydro and gas turbines can technically provide high ramp rates and can be made available to follow load.
