Electricity is flowing into the 50Hertz transmission grid for the first time via the grid connection for the Arcadis Ost 1 offshore wind farm in the German Baltic Sea off the coast of Rügen. Several of 27 wind turbines were successfully connected to the joint offshore transformer platform of wind farm operator Parkwind and 50Hertz. The commissioning of the wind farm with a total transmission capacity of 247 megawatts (MW) is planned for autumn 2023. By then, the offshore platform for Iberdrola's Baltic Eagle wind farm should also be installed and start operating in 2024.
"With the feed-in of wind energy from the first wind turbines we have reached another milestone on time. Previously, all three 220 kV cable systems for connecting the two offshore platforms Arcadis Ost and Baltic Eagle had already been successfully laid on the seabed and connected to the Lubmin substation via a short land route," explains Dr. Gerrit Mulert, overall project manager for Ostwind 2 at 50Hertz.
The expansion of the Lubmin substation was also successfully completed. To protect people and nature, among other things, twelve noise barriers up to 8.6 metres high were installed around transformers and compensation reactors. In addition, extensive species protection measures, such as amphibian relocation and replacement habitats for passerine birds, have been implemented on the site of the transformer sub-station.
