One of the world's biggest wind turbines with a hybrid tower is being built at the wind test site in Grevenbroich, Germany.
The tower combines a lower segment consisting of long, narrow pre-cast concrete components made by the Dutch company Advanced Tower Systems (ATS) and an upper segment made of conventional steel elements. Altogether the turbine will measure 180 meters with hub height at 133 meters. This tower enables a higher hub height to produce more energy at comparatively low overall cost. The various elements of the hybrid tower are designed to be easily transportable even to difficult locations The tower can also be installed quickly and can be combined with different brands of components (nacelles, rotors, etc.).
