Siemens Energy is supplying the HVDC power transmission technology for the offshore connection to a wind farm in the German North Sea. A contract has been signed between the network operator TenneT and the BorWin5 Offshore Consortium, consisting of Siemens Energy and Dragados Offshore .

The platform BorWin epsilon, part of the BorWin5 project, will begin in 2025 transmitting electricity from EnBW’s He Dreiht wind farm off the island of Borkum to the Garrel/Ost converter station 230 km away. It has a transmission capacity of 900 MW.

The scope of supply for Siemens Energy and its Spanish partner Dragados Offshore 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 AC produced by the wind turbines in DC at ±320 kV for transmission to land. The shoreside converter station in Garrel/Ost will then convert it back into three phase AC. 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.
