Europe’s energy future will never succeed without the close cooperation of European transmission system operators (TSOs) and not without the integration of the national transmission systems. This requires high capacity interconnectors, and an example of this is the Combined Grid Solution in the Baltic Sea. The first Danish-German offshore connection will link the German wind farm Baltic 2 with the planned Danish wind farm Kriegers Flak. The Project of Common Interest (PCI) is a joint venture by the two TSCNET shareholders Energinet, the Danish TSO, and 50Hertz, one of the four German TSOs.
After the gravity foundations for the two Kriegers Flak transformer platforms had been assembled on a special barge at the Belgian port of Ostend in December 2017, they were shipped to Denmark early this year. One of the platforms will be used for the Combined Grid Solution. Both are now in Køge harbour in the Danish region of Zealand, 39 kilometres southwest of Copenhagen, where they are waiting for the crane ship for the offshore installation. On the occasion of this project progress, 50Hertz has published an appealing time-lapse video of the platform’s assembly in Ostend, originally produced by the platform manufacturer, the Dutch Jan de Nul Group.
