Power technology group ABB has won an order worth around $700m (£460m) from German transmission-grid operator Transpower to supply an 800MW power link that will connect more offshore wind farms in the Dolwin1cluster, located in the North Sea, to the mainland German grid.
ABB will deploy its environmentally friendly 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 Dörpen, on the northwest coast of Germany, via 165km of underwater and underground DC cables.
The Dörpen/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, as well as offshore and onshore converter stations.
It will also supply and install the sea- and land-cable systems.
