ABB has installed a 320kV converter station for the DolWin2 wind project offshore German North Sea.


With a 916MW power transmission capacity, the DolWin beta converter station will connect offshore wind farms in the DolWin cluster with the electricity grid in Germany.

The station will convert alternating current (AC) generated from the offshore wind farms into high-voltage direct current (HVDC).

ABB CEO Ulrich Spiesshofer said: "After the successful handover of the DolWin1 link in July, this is another key milestone in the execution of our offshore wind projects."

ABB also installed sea and land cable systems and onshore converter station.

ABB Power Systems division president Claudio Facchin said: "Putting such a huge platform in place is one of the most delicate operations in the delivery of an offshore power link, requiring intensive pre-planning and cooperation between the stakeholders involved and we are pleased that this important project landmark has gone smoothly."

The DolWin2 wind project is part of Germany’s energy transition roadmap, Energiewende, which aims to have 6.5GW of installed offshore wind capacity by 2020 and 15GW by 2030.
