Max Bögl Wind is building four 178 meters hybrid towers, each with 3.4MW wind turbine capacity, as part of a pilot project in Gaildorf (Germany) from October 2017.
The idea behind combining two renewable energy sources in Gaildorf is that wherever concrete foundations are installed on a mountain, they can also be developed as water reservoirs. Thanks to the water storage facility in the tower foundation, added meters of hub height are obtained, thus leading to a higher wind yield. PE pressure pipes connect these upper reservoirs with a hydroelectric power station and the corresponding lower reservoir 200 meters below in the valley. The water battery reduces the need for chemical large-scale storage facilities and offers a natural alternative.
