The German company Enercon is responsible for making the world’s most powerful wind turbine. The Enercon E-126 stands tall at a height of 650 ft (198 m). Having a hub height of 443 ft (135 m) and a rotor diameter of 413 ft (126 m), it has the ability to produce 7.58 megawatts of power per turbine. The output power was originally 6 MW, but after a revision in 2009, it was increased to 7MW.
The weight of the foundation of the turbine tower is 2,500 tonnes. The tower itself has a weight of 2,800 tons and the machine housing weighs 128 tons. The generator and rotor, including the blade, have weights of 220 and 364 t respectively. This brings the total weight to about 6,000 tonnes. Building one such turbine costs $14 million, excluding installation costs.
The first such turbine went up in Emden, Germany in 2007 and since then, more than 150 of these turbines have been installed around the world. Check out this video for more details:
