Few months delay in the construction of converter Station in Bentwisch
Danish Energinet and German 50Hertz establish the world’s first offshore interconnection by using the national grid connections to offshore wind-farms in the Baltic Sea.
As eastern Denmark and Germany are two different synchronous areas, a frequency transformation is necessary. This will be done by two converters that convert the alternating current from the Nordic synchronous area into direct current and directly back to AC, now adapted to the European synchronous area. The so-called back-to-back converter is being installed in Bentwisch near Rostock, Germany.
The civil works and construction of the converter station have been delayed by a few months, which means that the interconnection is expected for launch in May 2019.
The delay that is primarily due to the overheated construction market in Germany, has occurred in the construction of the hall and the service building, which will house the converter. The specially designed converter with associated control systems and equipment for high-voltage connection was tested and is ready for installation as originally planned. All other milestones in the project have been achieved as planned. The offshore platform is installed and the cables are in place.

Tractebel is part of the Consortium that has been awarded a contract for the construction and installation of the Seamade offshore wind farms in the North Sea. The consortium will build the two high voltage substations, and their respective substructure, to be installed respectively in the Mermaid and the Seastar area.

The Kriegers Flak – Combined Grid Solution has reached another important milestone: Yesterday, German 50Hertz and Danish Energinet have successfully accomplished the 24 hours tests of both of the offshore cables connecting the Danish platform of the Kriegers Flak windpark with the German platform Baltic 2. One after another, the two cables „150-kV-line KFE-BaZ 155“ und „150-kV-line KFE-BaZ 156“ were energised and are now ready to transport the electricity.
Milestone reached by linking the Danish and the German transmission grids
