(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.
