Transmission system operator 50hertz, part of Elia Group, announced that the
Arcadis Ost offshore platform is now connected to the German extra-high voltage grid. Final assembly and commissioning works will now follow.

The 220 kV submarine cable system required for this was pulled into place on the platform over the past few days. The approximately 100-metre-long submarine cable had already been positioned and wet-stored on the Baltic Sea seabed in front of the platform, in 42 metres of water depth, in September 2021. Work on the cable follows the installation of the substation at the site
last month (June 2022).

"We are very proud that this operation was carried out quickly and safely and that we remain on time and on budget for the wider project,"
said Simon Deplace, Technical Project Director for Ostwind 2 at 50Hertz. The electricity generated by the wind farm north of the island of Rügen will in future be fed into the grid at the Lubmin substation.

50hertz is also developing the Ostwind 2 grid connection project connect the
Arcadis Ost 1 and Baltic Eagle wind farms to the German high voltage grid. To transfer the power from the two wind farms, 50Hertz is building three submarine cable systems that will transmit a total of 750 MW to the German transmission network at the substation Lubmin (Mecklenburg-Vorpommern).

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.

Iberdrola's 476 MW
Baltic Eagle project is being developed off the island of Rügen, in the German waters of the Baltic Sea. The project, which will span a 40 km2 area, is expected to be completed in 2024 and will consist of 50 Vestas V174-9.5MW wind turbines. It is Iberdrola's second array to be built in the Baltic Sea; the first was Wikinger.
