HVDC DolWin3 represents a high voltage direct current (HVDC) transmission system designed to deliver Offshore wind power directly to the German mainland electrical grid. Distinct from typical HVDC installations, this system features one converter station positioned offshore on a dedicated sea platform. It employs Voltage-Sourced Converters with a capacity of 900 MW and ±320 kV voltage rating, connected by cables extending 160 km in total length.
The development was executed by Alstom, with cable supply handled by Prysmian and the offshore platform constructed by Nordic Yards. Groundbreaking for the onshore converter facility at Dörpen West occurred in May 2014, followed by offshore platform construction commencing in October 2014. By mid-2015, outfitting of the platform was underway, and the initial converter transformer installation took place in July 2015. Ownership transferred to TenneT in 2017, with the system becoming operational as of September 2018. Investment in this offshore transmission asset was provided by a fund overseen by Copenhagen Infrastructure Partners.
