Got curious what the power rating of the blade pitch control system is. Couldn't find a size reference, but KEBA [1] sells motors and drivers at the 9 kW and 22 kW levels. Nidec [2] at 26 kW.
So just controlling the pitch (presumably of a more average turbine) uses the (peak) power of heating a house in Sweden. Noted that the duty cycle is low, but still.
