An innovative subsea cable TENNET DEVELOPS NEW CABLE WITH SUPPLIERS
40% OF THE DUTCH ELECTRICITY WILL COME FROM OFFSHORE WINDFARMS BY 2030. TENNET WILL REALISE THE GRID CONNECTIONS FOR THESE WINDFARMS. ALONGSIDE THE EIGHT 0.7GW AC GRID CONNECTIONS ALREADY PLANNED, TWO 2GW OFFSHORE GRID CONNECTIONS WILL BE built in the IJmuiden Ver wind energy area. Three additional 2GW offshore grid connections in the LanWin and Balwin area will lift TenneT’s offshore grid connection capacity in Germany to more than 17GW until 2030.

2GW offshore grid connection is currently non-existent. Innovation is needed and TenneT invited eight cable suppliers to develop these ‘next level’ subsea cable systems. This new cable system will set a new standard for connecting offshore windfarms. A 525kV HVDC extruded submarine cable system with a 2GW capacity is currently not implemented in any project worldwide. The development programme should result in a certified cable system that TenneT can apply in the IJmuiden Ver, BalWin and LanWin projects, as well as projects using the same power output and voltage. This will reduce costs and minimise spatial impact.
