AW - Model AW 750kW - 47m or 54m Rotor - Wind Turbine
When King-Sized Turbines Are Just Too Large: In an age of King-sized wind turbines designed for wide open spaces, Aeronautica Windpower is proud to introduce the 750 Series: Three-Quarter megawatt, 'Queen-size' machines designed for 'distributed wind' applications. Many good wind sites just cannot accommodate huge, utility-scale turbines. It is also ideal to be utilized for maximization of many state net metering legislations in place. A large number of sites, especially around populated areas,are better suited to a sub-utility size machine. The 750 is the perfect fit.

Product Details
More easily permitted, erected, serviced, and financed than its larger cousins, the 750 Series is a great choice for community wind projects, commercial/industrial sites, college or high school campuses, and other places where 'behind the meter', or net-metered power can be utilized. Yet they are also powerful enough to be used as a lower height alternative for many wind farm operations.
Aeronautica 750kW wind turbines are built according to strict IEC 61400 guidelines in our ISO 9001 rated factory to insure the highest degree of quality for a long service life. The Internet-ready SCADA system provides remote access and viewing from remote locations. Our time-tested gearbox isolation system absorbs shocks with ease, adding to long term durability. These turbines are ultra-quiet and highly transportable to reach areas otherwise inaccessible to larger machines.
With its low profile, ultra-low noise signature, and highly efficient output, our 750's provide the perfect balance between economic output and acceptable size. And Aeronautica wind turbines are manufactured in the United States, reducing shipping costs and delivery times.
