Transmission system operator 50Hertz has announced that all electrical systems have been installed in the Arcadis East transformer platform. It will support electricity transmission from the Arcadis Ost 1 wind farm.

Arcadis Ost 1 wind farm will have a capacity of about 257 MW and is located in the Baltic Sea, 19 km north-east of the island of Rügen, within the 12 nautical mile zone of the Federal State Mecklenburg-Western Pomerania, Germany. Parkwind secured grid capacity for the project in the offshore wind auction in Germany back in 2018. Offshore installation works are expected to start works in 2022. It is expected to be operational in 2023, and will be capable of generating enough green electricity for the annual power consumption of more than 290,000 homes.

The energy generated by the wind turbines is transported to the transformer platform at a voltage level of 33 kilovolts. The task of the platform is initially to bundle the incoming electricity and raise it to a voltage level of 220 kilovolts using a transformer. The electricity is then sent via the substation using a submarine cable system in the direction of the coast to the Lubmin substation in Mecklenburg-Western Pomerania. Here, the electricity is transformed to 380 kilovolts and integrated into the 50Hertz high-voltage transmission grid.

The platform forms part of the Ostwind 2 grid connection project which aims to connect the
Arcadis Ost 1 and Baltic Eagle projects to the German high-voltage grid. The Arcadis Ost substation is a joint project of 50Hertz and Parkwind. Including the technical equipment, it weighs around 2,400 tons and is 30 meters high.

"We are pleased that the Ostwind 2 project is still well on schedule. This brings us a good deal closer to the goal of climate neutrality,"
said Dr. Gerrit Mulert, overall project manager for Ostwind 2 at 50Hertz.

"In the next few weeks, the transformer platform will be shipped to its place of use 19 kilometers east of Rügen. There the platform will be assembled with the other two components, the so-called transition piece and the so-called monopile. Then the 50Hertz submarine cables that have already been laid are connected to the platform. Before it is finally completed and can be put into operation, several test runs must be successfully completed,"
said Matthias Wilhelm, Project Manager for Ostwind 2 at 50Hertz.

"The part up to the substation on land can be imagined as a freeway entrance, so to speak, from the substation we are then on the highway with the green electricity in the direction of consumption centers,"
added Mulert.
