The consortium was selected by 50Hertz in 2022 for the development of the two platforms and associated services. Allseas has been contracted to transport and install the substations, including the jackets, using its heavy-lift vessel Pioneering Spirit.
OSS Zingst and OSS Darß will collect electricity generated by Gennaker and transform it to 220 kV before the power is transmitted to the new Gnewitz substation onshore, approximately 70 to 90 kilometres away.
The two substations form the OST-6-1 grid connection for Gennaker East and Gennaker West. The transmission system has a capacity of up to 927 MW.
The Gennaker offshore wind farm is located approximately 15 kilometres north of the Fischland-Darß-Zingst peninsula in Mecklenburg-Western Pomerania, where 63 Siemens Gamesa wind turbines with a maximum capacity of 15.5 MW will be installed, resulting in a total Gennaker output of a maximum 976.5 MW.
Skyborn and 50Hertz signed an agreement in January that set out the framework for the two offshore platforms and cleared the way for the commissioning of the full grid connection system by mid-2028.
