[3] BorWin Alpha is the first HVDC converter station in the world to be installed on an offshore platform.

BorWin Alpha converts the power generated in offshore wind park BARD 1 into direct current at a voltage of 150 kV for HVDC-transmission to Diele.

Operating as static inverter valves, the station BorWin alpha uses not thyristors, but IGBT elements.

BorWin alpha was built in a shipyard in Vlissingen, Netherlands with electrical equipment from ABB.

The equipment was dragged with the SSCV Thialf to the place of assembly and installed at the end of May and the beginning of June 2009.
