50Hertz and Skyborn have awarded platform orders for the OST-6-1 grid connection for the 927MW Gennaker offshore wind project in the German Baltic Sea.
The consortium consists of HSM Offshore Energy, Smulders and Iv-Offshore & Energy and will be responsible for the planning, procurement, construction, installation and commissioning of the substations and the foundations, the so-called jackets.
50Hertz is responsible for the entire grid connection project under the name grid connection OST-6-1 which will absorb the wind power fed into the two transformer platforms by Skyborn and transporting it further at the extra-high voltage level of 220 kV and feeding it into the onshore German electricity transmission grid.
Three submarine cable systems are to be built for transport to the coast.
The cable route to the new transformer station to be built on land in the Sanitz/Gnewitz/Dettmannsdorf/Stadt Marlow search area will be around 90 km long, of which more than 50 km will be submarine cables on the Baltic Sea floor.
The project grid connection OST-6-1 is being prepared for the planning approval procedure at the Ministry of Economic Affairs, Infrastructure, Tourism and Labour of the State of Mecklenburg-Western Pomerania.
The work will be carried out at shipyards in the Netherlands and Belgium.
A few weeks ago, the consortium was commissioned to build an offshore transformer platform for the Ostwind 3 project.
The grid connection project Ostwind 3 is to connect the Windanker offshore wind farm north-east of Rügen.
Stefan Kapferer, CEO of 50Hertz, said: “The grid connection for the Gennaker wind farm is one of our top projects in the next ten years, along with the grid connection projects northeast of Rügen and the german-Danish joint project Bornholm Energy Island.”
OWP Gennaker, a subsidiary of Skyborn, will build the Gennaker wind farm around 15 km north of the Fischland-Darß-Zingst peninsula.
The project area is located in a priority area for offshore wind energy in the territorial sea of Mecklenburg-Western Pomerania.
The Gennaker project has had a building permit since May 2019.
It will feature 103 offshore wind turbines from Siemens Gamesa.
In recent months, discussions have already been held with municipalities in the sense of early public participation and information has been obtained.
