50Hertz and wind farm operator Skyborn Renewables seek to jointly implement Gennaker, currently the largest offshore wind project in the German Baltic Sea at 927MW capacity.
With a total capacity of nearly 1GW, Gennaker will be the most powerful offshore wind farm in the German Baltic Sea to date.
A Dutch-Belgian consortium
To implement the project, 50Hertz has laid the foundations for the development of two substations by a Dutch-Belgian consortium and Skyborn has fulfilled requirements for a grid connection.
The consortium consists of the companies HSM Offshore Energy, Smulders (a steel construction company) and Iv-Offshore & Energy. They won the tender for the development of the platforms and connected services.
Together, the consortium will be responsible for the planning, engineering, procurement of components, construction, offshore installation and commissioning of the substations and of the foundations, the jacket.
The work is to be carried out on yards in the Netherlands and in Belgium.

“Offshore wind is an essential component to increase the share of renewable energies in the electricity supply to 80% by 2030. In this respect, the swift realisation of the Gennaker project is of elementary importance in order to achieve the climate targets in Germany and Europe,” said Achim Berge Olsen, CEO of Skyborn.
“Securing the grid connection is an important milestone for the Gennaker project. This puts further planning on a solid foundation. We are looking forward to implementing this ambitious project together with a reliable partner like 50Hertz,” Berge Olsen adds.
OWP Gennaker GmbH, a subsidiary of Skyborn, will realise the Gennaker wind farm around 15km north of the Fischland-Darß-Zingst peninsula. The project area is located in a priority area for offshore wind energy in the coastal sea of Mecklenburg-Western Pomerania.
The Gennaker project has had a building permit since May 2019. Around the Baltic 1 wind farm, which has already been in existence for more than ten years, 103 high-performance offshore wind turbines from Siemens-Gamesa are also to be grouped.
OST-6-1
The project is part of a larger grid connection being run by 50Hertz, the Grid Connection OST-6-1.
In the project, generated wind power will be collected on two offshore platforms and transported at the 220kV level. Tree submarine cable systems will be installed to transport the electricity to the mainland.
The cable route up to the new substation – to be built in the Sanitz/Gnewitz/Dettmannsdorf/Marlow survey area – will be around 90km in length, of which 50km as a submarine cable on the seabed.
OST-6-1 is currently being prepared for the planning approval procedure at the Ministry of Economics, Infrastructure, Tourism and Labour of Mecklenburg-Western Pomerania.
