HVDC DolWin3

HVDC DolWin3 is a high voltage direct current (HVDC) link under construction to transmit Offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 160 km.

The overall project is being built by Alstom with the cables supplied by Prysmian and offshore platform by Nordic Yards. Construction commenced on the onshore converter station at Dörpen West in May 2014 ^[1] and on the offshore platform in October 2014.^[2][3] As of summer 2015 the platform was being fitted out and the first converter transformer was installed on 17 July 2015.^[4] The project is expected to be handed over to its owner, TenneT, in 2017.
