Walting Wind Park: Citizen Wind Project for renewable energy

Recently, the Walting Wind Park was built in Eichstaett near Ingolstadt, Germany. The residents in this area can take shares in this special Citizen Wind Project.

The project consists of three wind towers with hub heights of 139 m and total heights of 199 m. The towers are equipped with General Electric Type G 04 wind turbines and have rotor diameters of 120 m. The nominal capacity of the 3 towers is 2.78 MW per tower per year.

Savings of 1.6 million litres of fuel oil per year

The new wind park will generate approx. 16 million kilowatt hours of electricity per year, which roughly equals savings of 1.6 million litres of fuel oil.

Hybrid towers consisting of concrete and steel

The wind towers are hybrid towers consisting of concrete and steel. The lower portions of the towers are concrete half shells to a height of approx. 80 m. After erecting the concrete elements, the segments were post-tensioned using external tendons that ensure the stability of the towers when subject to dynamic loads.

60 tendons in lengths of 76 m and with a total weight of approx. 96 t were installed inside the 3 towers. The installation of the tendons was carried out by tailor-made uncoiling devices from the top down using a crane.
