The analysis shows that Let seng is a Class 4 site with 95% C.I. of both the bi-annual mean wind speed given by 5.97 0.07 m s and the bi-annual mean power density of 208.56 7.31 W m2 both calculated at 10 m a.g.l. The minimum speed is hardly ever below 3 m s and the maximum speed also is hardly ever above 25 m s which are usually the cut-in and cut-out speeds for most turbines. respectively. this results in the bi-annual turbine operation availability of 82.8 6.7%. This means the plant will be operational most of the time and there is no danger of structural damage due to high wind velocities as the maximum average gust is at a moderate 10 m s. Although the power density is slightly low due to the low density of 0.875 kg m3 primarily because of the high altitude of about 3000 m. the site has a potential of producing electricity for large-scale distribution as opposed to two other sites Masitise and Sani which were recently analyzed [2]. Masitise is a class 2 site while Sani falls under class 3. Both sites may not be ideal for gridconnected electricity production but they have sufficient wind for off-grid electricity production.
