Senvion SE, one of the largest turbine suppliers to the offshore wind industry, and a wholly-owned subsidiary of Suzlon, the fifth-largest wind turbine manufacturer in the world, is delivering 54 wind turbines for the offshore wind farm Nordsee One in Germany´s North Sea, which will be erected about 40 kilometres north of the island Juist.
Due to the long distance to the mainland, the wind farm will not be visible from the coast. Senvion and the project corporation Nordsee One GmbH signed the contract for delivery, installation and commissioning of the 54 Senvion 6.2M126 in December 2014 in Hamburg. The financing contracts have now also been signed. Each turbine has a rated power of 6,15 megawatts (MW), enabling it to supply about 4,000 households with energy. After the planned completion in autumn 2017, the Nordsee One offshore wind farm will have an installed capacity of approximately 332 MW and be able to supply more than 215,000 households with power in a year.
Andreas Nauen, CEO of Senvion SE, says: “A successful energy transition needs offshore wind energy. Clear framework conditions will fill the order books again. We are very happy that we are realizing this project with RWE Innogy and Northland Power. With our tried-and-tested technology we achieve an average of 4,000 full load hours offshore. With that we make our contribution to the network stability.”
The turbines and rotor blades are produced by Senvion and PowerBlades in Bremerhaven. The nacelle alone is as big as two single-family-houses and will be assembled offshore at a hub height between 97 and 100 metres. Each rotor blade is more than 60 metres long and weighs about 23 tonnes. The rotor star has a diameter of 126 metres, with the rotors sweeping an area larger than two football pitches.
To date, the Senvion 6.2M126 is the world´s most powerful offshore wind turbine to be produced in series. Senvion got started in the multi-megawatt category back in 2004 and since then has achieved a great deal of success. No other manufacturer today competes with the experience of Senvion, with more than 140 turbines from the 5 and 6 megawatt class installed on the high seas.
