Wind turbine with the world's largest rotor goes into operation

On October 6 2012, Siemens began field testing of its new 154-meter rotor for the six-megawatt (MW) offshore wind turbine in Řsterild, Denmark. The direct-drive wind turbine is equipped with the world's longest rotor blades – each blade measures 75 meters in length. With a record rotor diameter of 154 meters, each SWT-6.0-154 turbine can produce 25 million kilowatt hours of clean electricity in offshore locations, enough to supply 6,000 households. Řsterild is a windy site near the coast and offers very favorable conditions for initial testing on shore.
