on temperature, weather, geographic location (elevation and terrain), and time (of day and
season). The power law prole is typically used in engineering studies.
Consider Table 3.4 that shows the calculated wind speeds for two different values of α at
a height of 100 m, which is the typical hub height for modern commercial WTs. The change
in predicted power based on these wind speeds is the ratio (13.6/11)
3
= 1.89. This indicates
that the predicted power can nearly double at 100 m if the value of α increases from 0.14 to
0.23. This has large economic implications. In other words, determining the ...
