ABB Awarded Maintenance Order For Offshore Wind Power Link


ABB says it has signed an agreement with Dutch-German transmission system operator TenneT to provide maintenance services for the DolWin2 link, which will bring power from offshore wind farms, located in the North Sea, to the mainland German grid.

As part of the maintenance contract, ABB will keep up the land- and sea-based high-voltage direct-current (HVDC) converter stations that will connect the wind farms via an offshore platform to the grid.

ABB is also providing the power link itself, which the company says represents the largest power transmission order in its history. DolWin2 will have a rating of over 900 MW, keeping electrical losses to less than 1% per converter station, according to ABB.

Scheduled to be operational in 2015, DolWin2 will link the 400 MW Gode Wind II wind farm and other offshore wind farms to the grid. The completed link will be capable of supplying more than 1.5 million households with wind-generated electricity, ABB notes.
