Size specifications of common industrial wind turbines

Vestas and General Electric (GE) dominate the market for industrial wind turbines in the U.S. Many older U.S. facilities use NEG Micon turbines, and Vestas has absorbed that manufacturer. Other older facilities use turbines from Zond, which was acquired by Enron (the inventor of "green tags"), whose wind business GE acquired in turn to take over the racket. Click the following company names for more information from their own web sites: Vestas, Gamesa, GE, Siemens, Suzlon, Senvion (Repower acquired by Suzlon in May 2007, renamed in January 2014), Clipper, and Mitsubishi. Nordex, Enercon, Americas Wind Energy, and Goldwind are also major manufacturers, but their turbines are less common in the U.S.

*This figure is actually half the rotor diameter. The blade itself may be about a meter shorter, because it is attached to a large hub.
†Hub (tower) heights may vary; the more commonly used sizes are presented.
‡Rotor diameter (m) × π × rpm ÷ 26.82
§The rated, or nominal, wind speed is the speed at which the turbine produces power at its full capacity. For example the GE 1.5s does not generate 1.5 MW of power until the wind is blowing steadily at 27 mph or more. As the wind falls below that, power production falls exponentially.
