ABB successfully commissioned the subsea transmission link connecting one of the largest offshore wind farms in Europe to the Belgian grid. The Thornton Bank project, executed for the Belgian company C-Power NV was completed on schedule. The transmission link was constructed as part of an expansion of the Thornton Bank wind farm. As part of the turnkey project, ABB was responsible for the system engineering, design, supply and commissioning of the alternating current (AC) subsea cables, the land-based cable systems as well as the offshore substation and platform that houses it. The wind turbines are connected via underwater medium-voltage cables to the offshore transformer station where the voltage is boosted to 150 kV and connected to the mainland grid. The electricity is then fed into the grid at the Slijkens high-voltage substation located at Bredene.
