HVDC DolWin1 is an HVDC link under construction, which should connect the Borkum-West II offshore wind park with the power grid of the German mainland. The link will consist of a 165 kilometres (102.5 mi) long bipolar cable, from which 75 kilometres (46.6 mi) will be laid in the sea and 90 kilometres (55.9 mi) underground on land.

The converter station for Borkum-West is planned to be built on the offshore platform DolWin Alpha, that for feeding the power in the 380 kV grid at Dörpen-West/Heede at 52°58′52"N 7°15′26"E.

HVDC DolWin1 will be a bipolar HVDC with a voltage of 320 kV and a transmission capacity of 800 MW. As valves in both stations IGBTs will be used. The link, which will be completed in 2013, will be built by ABB and operated by TenneT
