Combined Grid Solution: submarine cable installed

06.07.2018

In early May, all of the three offshore platforms for the planned Danish wind farm Kriegers Flak in the Baltic Sea were successfully installed. One of them will not only collect wind power, but also function as linking point for the Combined Grid Solution, the first Danish-German offshore interconnector. The Combined Grid Solution is a joint venture of two TSCNET shareholders, 50Hertz, one of the four German Transmission System Operators (TSOs), and the Danish TSO Energinet.

Just two months later, 50Hertz announces that the next significant step for the project has been taken. The Combined Grid Solution will integrate the electricity systems of Denmark and Germany by linking the German wind farm Baltic 2 with 25 kilometres of submarine cables to Kriegers Flak. Now both cables of the interconnector have been laid out completely. The Baltic 2 platform was the starting point for the cable laying, and on 5 July, the Kriegers Flak platform was reached.

Elke Kwapis, project manager at 50Hertz, acknowledges the good cooperation with Energinet in this process and states: “These are great news. In the business everybody knows how complex the installation of submarine cables can become.” Especially in this case, it was even more challenging than usual, because the Baltic 2 platform was constantly in operation during the cable laying.
