HVDC BorWin3 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.

[1] It is being built by the Siemens/ Petrofac consortium with the offshore platform contract awarded to Drydocks World in Dubai.

The project started power transmission in August 2019.
