Energinet.dk: Traditional Grid Connection at Kriegers Flak

Energinet.dk is preparing for the construction of a traditional grid connection system for the wind turbines at Kriegers Flak.

Originally, the grid connection should have been based on a DC system to be combined with an electrical connection to Germany via the Danish and German offshore wind farms in the Baltic Sea. However, this technical solution has been abandoned, as a call for tenders for the converter stations showed that especially the offshore converter station was far more expensive than estimated. Consequently, the electrical connection in the planned solution would not be economically profitable.

Energinet.dk will  submit an application to the Danish Minister for Climate, Energy and Building for approval of the investment before Energinet.dk can start building the grid connection.

The offshore grid connection system will consist of two 220 kV offshore trans-former platforms, which accumulate the electricity generated by the wind turbines in the 600 MW offshore wind farm.

The two platforms are mutually connected by a submarine cable. An approximately 45 km long 220 kV submarine cable will be laid from each platform to the Zealand coast.
