The patented hybrid tower combines a pre-cast concrete segmented tower with tubular steel sections on top. The lower tower sections, which require a diameter bigger than the 4.3m transport limit, are vertically divided into three or more slender segments made of high-quality pre-cast concrete. The segments can be easily transported via ordinary trucks. The installation of the entire tower takes less than a week and can be done under most weather conditions.

The ATS tower does not have a circular cross section, but is square or triangular, with rounded corners. The corner elements are all identical and are therefore made with one single mould. The flat elements are poured on a flat table with adjustable sides.

The cost of ATS hybrid towers are comparable to those of other tower concepts. ATS towers turn out to be commercially attractive for large wind turbines, but also for 'smaller' turbines (1.5-2 MW, 75-100m), especially in those countries where the transportation of steel towers is problematic and where the concrete segments can be produced locally instead.

The new tower concept offers:

Larger hub heights - more energy production
Transport flexibility and short installation time - low cost
Worldwide production by its proven concrete technology - local employment.
