Strong Teamwork: The Wind Power Network
More than 2,800 wind turbines with a total capacity of 2,900 megawatt provide more than just wind in the energy supply of North Rhine-Westphalia. From modest beginnings in 1982 with the first 20-kW wind turbine to go on stream in Mettingen, and an energy resource has been developed and established within just less than 30 years with which 3.71 % of the net power consumption in North Rhine-Westphalia can be covered. Whereas until the end of the last millennium the windmill operators tended to regard their turbines or stakes in them as personal contribution to climate protection with an ecological return, with the erection of the first wind farm there was a shift in emphasis and it was considered more as a strategic capital investment. In terms of installed capacity, the State – despite its landlocked situation – is now one of the top five in Germany; 11 % of power from wind energy nationwide is generated here. And whereas the average output of a turbine was 115 kilowatt (kW) in 1993, today it is a little more than 1,000 kW.
