Capacity classes


In 2018 there was, for the first time, a clear trend towards wind turbines with an output of more than 4 MW. Almost 16 percent of the wind turbines installed in 2018 had a corresponding capacity, which corresponds to a fivefold increase in the share from 2017 (almost 3 percent). The 3-4 MW power class has further expanded its market share, reaching almost 70 percent. It is to be expected that the maximum market share of this class has now been reached and will stagnate in the future or decrease again in the medium term in favour of wind turbines with a capacity of more than 4 MW. Only 14.5 percent of the wind turbines still had an output of less than 3 MW.

In the 4 - 5 MW power class, eight different types of turbines were installed in 2018, led by the Enercon E-141 EP4. Furthermore, the Enercon E126 with 7850 kW is the only installed system type with more than 5 MW capacity. The average rated capacity of the wind turbines installed in 2018 made a significant leap and was 3.34 MW, compared with 2.98 MW in the previous year. At the same time, 50 percent of the wind turbines had a narrow output range of 3 - 3.45 MW. Neglecting small wind turbines, the total range of installed rated output was between 750 kW and 7.6 MW.
