Jan De Nul Group together with its consortium partners LS Cable & System and Denys signed the contracts for two 525 HVDC cable systems for the two grid connection systems BalWin4 and LanWin1. These mark the first two contracts signed under the long-term framework agreement that TenneT and Jan De Nul have signed earlier this year.
The projects comprise the design, manufacturing, transport, installation, protection and testing of three 525 kV cable systems for connecting offshore wind farms to the onshore grid via the BalWin4 and LanWin1 grid connections. Jan De Nul will take care of the transport, installation, burial and protection of the offshore cables. LS Cable & System will design, manufacture, terminate and test all cables with Denys being responsible for civil and cable pulling scope related to the onshore cable routes.
The cable systems of the two grid connections BalWin4 and LanWin1 coming from the offshore converter stations will cross the Wadden Sea and be connected to the extra-high voltage grid in Unterweser, Germany. The grid connections will enable renewable electricity from offshore wind farms with a transmission capacity of altogether 4 GW to be fed into the German grid.
