The new turbine features a rotor diameter of 152 m, with the rotors sweeping an area larger than three football pitches. The nacelle alone is as big as two detached houses and will be constructed offshore at a height of between 95 and 110 m.
The larger rotor diameter, when compared to the a previous product, the REpower 6.2M126 (126 m), achieves an increase in energy yield by up to 20 per cent at wind speeds of 9.5 m/s. With a rated power of 6.15 megawatts, each REpower 6.2M152 turbine can supply around 4,000 homes with electricity.
“We are the only manufacturer to have already installed more than 100 offshore turbines in the multi-megawatt class,” said Andreas Nauen, CEO of Suzlon subsidiary Repower Systems SE. “With an eye on the outstanding availability and energy yield of the REpower 6.2M126, we have enhanced this robust, proven concept: the bigger rotor and correspondingly larger drive train of Repower 6.2M152 combined with tried-and-tested, first-class technology enables our customers to generate energy even more cost-efficiently on the high seas.”
Repower has already sold a prototype REpower 6.2M152. Together with the customer, it has been agreed to construct the prototype with a hub height of 124 m at an onshore site in northern Germany, with construction scheduled for completion by the end of 2014. From 2015, REpower 6.2M152 will enter commercial production.
