At the EWEA OFFSHORE 2013, the Suzlon Group – the world’s fifth largest wind turbine manufacturer – will unveil its new offshore turbine, the REpower 6.2M152.
The new turbine features a rotor diameter of 152 metres, 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 metres. The larger rotor diameter compared to the last generation – the REpower 6.2M126 (126 metres) – 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.
Andreas Nauen, CEO of REpower Systems SE , said: “We are the only manufacturer to have already installed more than 100 offshore turbines in the multi-megawatt class. 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.”
The Hamburg-based company has already sold the prototype REpower 6.2M152. Together with the customer, it has been agreed to construct the prototype with a hub height of 124 metres 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. REpower already manufactures the world’s most powerful commercially-produced offshore turbine. Since introducing its multi-megawatt offshore turbines ten years ago, REpower has constructed more than 100 turbines of this platform.
