Offshore Wind Connection Contract for ABB

Power and automation technology group ABB has won a significant order from the Dutch-German transmission system operator TenneT to supply an AC (alternating current) power transmission link connecting Sandbank, an offshore wind farm in the German North Sea, to the HVDC (high-voltage direct current) converter station SylWin alpha.

The link will have the capacity to transmit 288 megawatt (MW) of clean wind power – enough to supply energy to around 300,000 German households. Once the connection is commissioned the offshore wind farm will be able to save 1,500,000 tons of carbon dioxide emissions per year by replacing fossil fueled generation.

“Germany’s focus on renewable energy, the so-called ‘Energiewende’, together with the growing interest in using wind as an energy source in Europe provides significant opportunities for us,” said ABB CEO Ulrich Spiesshofer. “Integrating renewable wind energy efficiently and reliably helps deliver clean and affordable electricity to consumers in an environmentally sustainable way.”

The connection will deploy two 3-core 155 kilovolt (kV) AC submarine cables, each 36 km long. ABB has already successfully commissioned nine AC cable projects worldwide for offshore wind connections and others are under execution.
For this project ABB will have turnkey responsibility for the design, engineering, supply and installation of the subsea cable system including two shunt reactors on the AC platform. The project is scheduled for completion in 2015.
