Belgian marine contractor Jan De Nul and consortium partners LS Cable & System, and Denys have been awarded a cable system portfolio for the German electricity grid by TenneT.
BalWin 4, LanWin 1, and LanWin 5 are cable systems consisting of both offshore and onshore sections, while the NordOstLink is an onshore cable system. The combined DC cable length of the awarded portfolio is almost 2,000 km.
TenneT is heavily investing in the grid connections of offshore wind farms for both the Dutch and German energy grid, for which these cable system packages are designed. BalWin 4 and LanWin 1 will connect to the Unterweser area, LanWin 5 to Rastede. All grid connections will have a capacity of 2 GW each and will be operational, respectively, by 2029, 2030, and 2031.
The three partners in the consortium all bring their own expertise to the table, with LS Cable & System responsible for cable design and manufacturing, Jan De Nul for offshore cable installation, and Denys for onshore cable installations.
Jan De Nul’s scope includes the transport, installation, and protection of the cables in the Wadden Sea, nearshore, and offshore sections for the cable system packages of BalWin 4, LanWin 1 and LanWin5. The offshore operations will start in 2026.
Also on Friday, cabling contractors Nexans and NKT sealed deals for three grid projects each, connecting future offshore wind farms in the German and Dutch North Seas, respectively.
