50Hertz connects Arcadis Ost offshore substation to German grid

Germany: Transmission system operator 50Hertz has announced that the Arcadis Ost 1 offshore substation has been connected to the German extra-high voltage grid.

To do that, the 220 kV submarine cable required for this was pulled into place on the platform over the a couple of days earlier.

Final assembly and commissioning works will now follow.

“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 work on the cable follows last month’s installation of the substation at the project’s site located in the West of Arkona cluster.

Ostwind 2 is the project to connect the Baltic Sea wind farms Arcadis Ost 1 and Baltic Eagle to the German extra-high voltage grid. To transfer the power from the two wind farms, 50Hertz plans to build three submarine cable systems that will transmit a total of 750 MW of power.

The laying of the second cable system was completed in December 2021 by a consortium of NKT and Boskalis.
