The anemometer height is the height above ground at which the wind speed data are measured. Wind speeds tend to increase with height above ground, so if the wind turbine hub height is not the same as the anemometer height, HOMER adjusts the wind speed data accordingly. A common anemometer height for meteorological measurements is 10m. Anemometers installed specifically to determine wind power potential are often placed higher than 10m, because wind turbine towers are typically between 25m and 100m in height. The closer the anemometer is placed to the eventual hub height of the wind turbine, the more accurately it measures the wind resource to which the wind turbine is exposed.

 

For details on how HOMER calculates the wind speed at the hub height of the wind turbine, see Wind Resource Variation with Height.
