PUB - Development of a transition piece for a self-erecting wind energy plant


For the construction of wind towers with large hub heights up to 200m, the FOSTA research project HYTOWER  investigated a concept for a self-erecting wind energy plant with steelsteel hybrid tower. A tubular steel tower is lifted inside a lattice tower using a strand lifting system. During this process the tubular steel tower is stabilized by hydraulic cylinders. A specially developed transition piece is used to accommodate the lifting system during the lifting process and to finally connect the two tower parts. In this paper, the erection process as well as the development of the transition piece is presented.

The European Union has set itself the goal of increasing the share of renewable energies in gross final energy consumption to at least 32 % by 2030. Furthermore, there is a plan to achieve climate neutrality in the EU by 2050. To support the EU's climate target plan, the Federal Republic of Germany has set its own national targets through the Erneuerbare-Energien-Gesetz (Renewable Energy Sources Act - EEG). According to these targets, renewable energies are to reach a share of 65 % of gross electricity consumption by 2030. By 2050, Germany's entire electricity consumption is to be covered in a greenhouse gas-neutral manner
