Wind Turbine Tower Size

Size of Wind Turbines:

The area of the disc covered by the rotor, (and wind speeds, of course), determines how much energy can be obtained from the turbine. The picture gives an idea of the normal rotor sizes of wind turbines: A typical turbine with a 600 kW electrical generator will typically have a rotor diameter of some 44 meters (144 ft.). If the rotor diameter doubles, we get an area which is four times larger (two squared). This means that power output from the rotor also increase four times. Rotor diameters may vary somewhat from the figures given above, because many manufacturers optimise their machines to local wind conditions.
