Turbines Technology Continues to Astonish the Masses!
The world’s largest wind turbine is now the Enercon E-126. This turbine has a rotor diameter of 126 meters (413 feet). The E-126 is a more sophisticated version of the E-112, formerly the world’s largest wind turbine and rated at 6 megawatts. This new turbine is officially rated at 6 megawatts too, but will most likely produce 7+ megawatts (or 20 million kilowatt hours per year). That’s enough to power about 5,000 households of four in Europe. A quick US calculation would be 938 kwh per home per month, 12 months, that’s 11,256 kwh per year per house. That’s 1776 American homes on one wind turbine.
The E-126]… has no gearbox attaching the turbine blades to the generator, in fact, the generator is housed just at the widest part of the nose cone, it takes up the entire width of the nacelle to generate power more efficiently, and provide longer service life with less wear.
The turbine being installed in Emden, Germany by Enercon. They will be testing several types of storage systems in combination with the multi-megawatt wind turbines.
These turbines are equipped with a number of new features: an optimized blade design with a spoiler extending down to the hub, and a pre-cast concrete base. Due to the elevated hub height and the new blade profile, the performance of the E-126 is expected to by far surpass that of the E-112.
