“We are especially pleased that we can again join with TenneT to make an important contribution to the decarbonisation of Germany’s energy supply. The seventh order in the German North Sea underscores the great confidence in our HVDC technology,” emphasises Beatrix Natter, Executive Vice President of the Transmission Division at Siemens Energy. “When DolWin6 and BorWin5 begin operation, we’ll have installed a total transmission capacity for 5.6 GW of wind power in the German North Sea. This could supply around seven million German households with green electricity.”
The scope of supply for Siemens Energy and its Spanish partner Dragados Offshore S.A. includes the turnkey construction and installation of the offshore platform in the North Sea and the converter station on land. The offshore converter station will convert the three-phase alternating current produced by the wind turbines into direct current with a voltage of ±320 kV for low-loss transmission to land. The shoreside converter station in Garrel/Ost will then convert the electricity back into three-phase alternating current for feeding into Germany’s power grid. Siemens Energy will supply the HVDC technology required for the project and build the shoreside station, while Dragados will be responsible for the design, procurement, construction and installation of the offshore converter platform.
