Description
TenneT awarded Nexans Norway AS a turnkey contract to supply and install the 320 kV HVDC export cable system for the BorWin6 grid connection in the German North Sea. Under this EPC(I) agreement, Nexans will design, manufacture, deliver, lay and protect single-core XLPE DC cables for both the subsea and onshore sections linking the BorWin kappa offshore converter platform to the onshore converter and substation at Büttel. The scope covers two parallel pole cables along the full route, amounting to approximately 380 km of subsea cable (2 × 190 km) produced at Nexans’ Halden plant in Norway and around 92 km of land cable (2 × 46 km) produced at Charleroi in Belgium, plus associated fibre optic and reserve lengths. Nexans is also responsible for installation across the sea, Wadden tidal flats and land sections, with main laying operations scheduled from 2025 to enable commissioning of the 980 MW BorWin6 connection in 2027.
