Securing supply with HVDC

Nexans is to provide 170kV XLPE submarine cables to increase power capacity across three fjords, Gimsøystraumen, Nappstraumen and Flakstadpollen, in moves to strengthen the power supply for residents throughout Lofoten, Norway. The improvements will include increasing the current grid capacity from 66kV to 132kV. Lofotkraft AS is upgrading the submarine cable in all three fjords to extend longevity and increase transmission capacity. Nexans Norway will supply the cables with all transition joints, end terminations and contingency repair joints. Work on the project is already underway, with supply of the cable scheduled for spring 2017 from Nexans’ Halden, Norway plant. Strengthening Norway’s supply

TenneT TSO BV and Energinet dk SOV have awarded the contract for an HVDC submarine interconnector to Prysmian Group. The COBRA (Copenhagen Brussels Amsterdam) cable, linking Denmark and the Netherlands, will make Dutch power capacity structurally available to Denmark and vice versa, increasing security of supply and enabling the further integration of renewable energy into the electricity grids. COBRA is supported by the European Union through its EEPR (European Energy Programme for Recovery). Prysmian’s contract involves the supply and installation of an HVDC bipole, operating at a voltage level of ±320kV with a rating of approximately 700MW. It will run along a total route of around 325km, including two onshore lengths of 1km, on the Dutch side, and 25km, on the Danish side, to link to the onshore converter stations. All cables will be produced in Arco Felice and Pikkala, the group’s technology centers for submarine cable. The marine cable laying will be performed by the group’s own vessels, the Cable Enterprise,and the Giulio Verne .
