Optimized wind towers for new market conditions

Max Bögl Wind AG releases the next generation of its Hybrid Tower system – The result: A further optimized tower design that brings the new high-performance turbine generators up to the hub heights dictated by the market and makes hybrid tower construction even more cost-effective.
They are already higher and generally more efficient than alternative tower designs. The Hybrid Towers of Max Bögl Wind AG combine concrete and steel and allow hub heights of up to 190 meters. The company has now developed the 2.0 version of its Hybrid Tower, which requires less material while still ensuring the highest stability. The new system is even more cost-effective due to changes to the foundation and interior construction and the revised segmentation and geometry of the towers.


Innovative power for more cost efficiency

The new foundation design simplifies pre-tensioning at the input level of the wind turbine and thus streamlines operation. Higher fatigue strengths are achieved and stress peaks in the structure are further reduced. With the conical shape of Hybrid Towers mb 2.0, less tendons are necessary by optimizing the load transference. The interior will now be constructed using a new procedure patented by the Max Bögl Group in which the lift and ladder are mounted during concrete tower erection. Due to the parallel installation process, assembly time is significantly reduced. Company engineers also focused on logistics and transport: In the future almost no heavy lifting devices will be necessary to transport the individual tower segments. Any standard truck can be used, which means wind turbines can now be erected in a far more flexible, faster and safer way.


Hybrid Tower 2.0 paves the way to a successful energy transition

“The market demands more cost-effective wind turbines to meet the new challenges created by the Renewable Energy Sources Act (EEG 2017). Turbine technology is becoming more powerful and rotors are constantly getting bigger and heavier,” says Josef Knitl, CEO of the Max Bögl Wind AG. “Our Hybrid Tower 2.0 is capable of meeting both structural as well as economic requirements. This allows for the continued expansion of renewable energies under the new market conditions.” To this end Max Bögl AG is developing customer-specific tower designs based on the hybrid tower 2.0 for the next generation of turbine generators.
