ABB, the leading power and automation technology group, has won an order from the Dutch-German transmission system operator, TenneT to provide maintenance services for the DolWin2 link bringing power from offshore wind farms, located in the North Sea, to the mainland German grid.

This contract follows ABB’s success earlier this year when it won an order worth around $1 billion to supply the power link itself, which was the biggest power transmission order in ABB’s history. DolWin2 will deploy the world’s largest offshore HVDC (high-voltage direct current) system with a rating of over 900 megawatts (MW), keeping electrical losses to less than 1 percent per converter station. The completed link will be capable of supplying more than 1.5 million households with clean wind-generated electricity.
