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 individual commissioning steps ask for a little more time as well as testing of all components of the converter station, which means that the interconnection is expected for launch in Q2 2020.
