DolWin2 will deploy an offshore high-voltage direct current (HVDC) system with a rating of over 900MW, keeping electrical losses to less than 1% per converter station.
The completed link will be capable of supplying more than 1.5 million households with clean wind-generated electricity, ABB said.
Under the three-year contract, which has extension options, ABB will keep up the land- and sea-based HVDC converter stations connecting the wind farms via an offshore platform to the grid.
DolWin2 links the 400MW Gode Wind II wind farm and other offshore wind farms to the grid.
Scheduled to be operational in 2015, DolWin2 will have onshore and offshore HVDC converter stations and 135km of underwater and underground DC cables.
