(a) Vertical extrapolation of wind speed based on the 1/7 power law

(b) Mean wind speed is based on the Rayleigh speed distribution of equivalent wind power density. Wind speed is for standard sea-level conditions. To maintain the same power density, speed increases 3%/1000 m (5%/5000 ft) of elevation.
(from the Battelle Wind Energy Resource Atlas)

 

 

Source:  American Wind Energy Association web page.  The table was developed by the Pacific Northwest Laboratory.  Wind densities at higher elevations typical of newer wind turbines have not been calculated. 

 

Category 4 wind class density is typically considered necessary for viable wind generation.  However, it is generally thought that category 3 conditions are adequate for many sites in Maine using newer wind technologies.
