Senvion SE, a wholly owned subsidiary of the Suzlon Group, the world’s fifth-largest manufacturer of wind turbines, finished commissioning and initial test phase of the prototype of the Senvion 6.2M152. The turbine with the largest rotor diameter in the Senvion product range has been operating in fully automatic mode and thus as an active power plant at Langen-Neuenwalde (Germany), about 20 kilometres north of Bremerhaven, since January. It generated the first kilowatt hour (kWh) on schedule on 18th December 2014 and received the Design Assessment. With a rated power of 6.15 megawatts, the Senvion 6.2M152 can supply around 4,000 homes with electricity.
Russell Stoddart, CTO of Senvion SE, says: “We are proud of the successful commissioning of this high-performance turbine in cooperation with our customer EWE ERNEUERBARE ENERGIEN GmbH. By the 6.2M152 entering the market, we are making the most powerful turbine in series-production to date (the Senvion 6.2M126) even more efficient. In our role as manufacturer, it is our responsibility to ensure wind energy is used as efficiently and reliably as possible. We know how to lower the power generation costs while also ensuring increased yield. Thanks to the greater reliability and more intelligent control of our turbines, we can meet our goal of delivering a state-of-the-art product at the best price/performance ratio for the offshore market.”
Compared with its predecessor (the Senvion 6.2M126), the rotor star of the Senvion 6.2M152 has a diameter of 152 metres, with the rotors sweeping an area larger than three football pitches. Thanks to a larger rotor diameter compared to its predecessor (126 metres), the energy yield at wind speeds of 9.5 m/s is increased by up to 20%. The bigger rotor and correspondingly larger drive train combined with tried-and-tested, first-class technology enables our customers to generate energy even more cost-efficiently on the high seas with the 6.2M152 with a design life of 25 instead of 20 years.
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 ever since then has achieved a great deal of success. No other manufacturer today can compete with the Senvion offshore experience with more than 140 turbines from the 5 and 6 megawatt class installed on the high seas.
