HVDC SylWin1 is a high voltage direct current (HVDC) link 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 864 MW, ±320 kV are used and the total cable length is 205 km. The project is similar to the HVDC BorWin2 project but has slightly higher power and voltage ratings. It is being built by the Siemens/ Prysmian consortium and was handed over to its owner, TenneT, in April 2015.^[1]
