The Hannover-Marienwerder wind power plant has been in operation in the Marienwerder district of Hanover since the end of November 2012 with an output of 1.5 megawatts. The system is a Vensys 77, with a total structure height of 138.5 m, 100 m of which is accounted for by the tower (the rest is accounted for by a rotor arm that is stretched vertically upwards). This makes it the first wind turbine in the world to use a wooden tower .

The wooden tower consists of 28 floors and has a stable octagonal outer wall of approx. 30 cm wall thickness made of plywood. About 1000 trees were felled to produce this tower (approx. 400 m³ of wood = approx. 200 t). The machine house and rotor of the wind power plant weigh around 100 t on the tower. About 70 wire tips protrude from the tower wall to divert lightning. A UV-stable PVC film forms the protective outer skin of the tower.
