Østerild, Denmark, 2012-Oct-08

Siemens wind turbine featuring the world's largest rotor goes into operation

Record-breaking rotor: World's largest rotor blade

On October 6, 2012, testing has started on the record-breaking rotor on the six-megawatt offshore Siemens wind power plant at Østerild, Denmark. At 75 meters each, for a total rotor diameter of 154 meters, the Siemens wind turbine's blades are the longest in the world in operation. The swept area is 18,600 square meters, or the equivalent of two and a half soccer fields. The start of test operations for the 154-meter-diameter rotor on the gearless six megawatt wind turbine represents an important step in the development of promising offshore technologies for the future.
