orwegian system operator Statnett and its Danish counterpart
Energinet.dk have signed contracts with cable suppliers for the fourth interconnector between Norway and
Denmark – known as Skagerrak 4. Te contracts have a total value of €127million and launch the construction phase of the project (Fig. 1). “Tese contracts are the first major contracts to be signed at the Skagerrak 4 project, and therefore mark a significant milestone for the project,” says project manager Arve Strandem at Statnett. Skagerrak 4 is planned to be completed by the end of 2014.
Te HVDC cable will be supplied by the cable manufacturers Nexans and Prysmian. Nexans will provide a 137km offshore cable and 12km onshore cable in Norway, while Prysmian will provide the 91km onshore cable to be installed in Denmark. Prysmian’s contract amounts to about €40million, whilst Nexans’ contract is worth approximately €87million. Te companies say that the interconnector
will facilitate more renewable energy production in both countries and benefit consumers and the industry through more stable power prices and increased security of power supply. Currently there are three DC connections
between Norway and Denmark, Skagerrak 1-3, with a total capacity of 1000 MW. Te new Skagerrak 4 interconnection will have a capacity of 700MW, which will increase the capacity by 70 per cent to 1700MW. Te total construction budget is around NOK 3 billion (€380million), also comprising two converter stations at Tjele in Viborg and Kristiansand in Norway. Costs are shared between the two companies. In a separate development, the NorNed cable has successfully joined the interregional market coupling between Central-Western-Europe (CWE) and the Nordic countries. Te cable couples France, Belgium, the
Netherlands, Luxemburg and Germany in the Central-West on one side, and Norway, Sweden, Finland, Estonia and Denmark on the other. Te inclusion of the NorNed with the undersea
