The reinforced concrete spread foundations are placed on an insulating expanded polystyrene layer. They redistribute the load over a doughnut-shaped surface, rather than sending them to the subsoil.

RWE described the turbines as “innovative”, and explained that they optimise the amount of concrete and steel used, making the project more cost-effective and environmentally more sustainable.
