ABB will deploy its HVDC Light transmission technology to transmit power from the 400MW Borkum West II wind farm and other wind farms to be developed nearby.

The wind farms will be connected to an offshore HVDC converter station, which will transmit electricity to the onshore HVDC station at Dorpen, on the northwest coast of Germany via 165km of underwater and underground DC cables. The Dorpen/West converter station will in turn feed AC power to the mainland grid.

ABB will be responsible for system engineering, including design, supply and installation of the offshore platform, the offshore and onshore converter stations, and will also supply and install the sea and land cable systems.

Scheduled to be operational in 2013, this network of offshore wind farms is expected to avoid three million tons of carbon dioxide emissions per year by replacing fossil-fuel based generation, ABB said.

According to the company, this is the second HVDC Light offshore wind connection supplied by it in Germany, the first being the BorWin1 project.
