A 37-year （1971-2007） wind speed data set measured at 10m height, obtained from eight meteorological stations within the region was analyzed using a 2-parameter Weibull function. Besides, a techno- economic evaluation of large wind energy conversion systems with power ratings ranging from 0.6 to 2 MW at different hub heights based on the levelized unit cost of electricity was made for the different sites considered. The result showed that electricity cost varied from 0.06997 and 0.11195 S/（kW. h） to 2.86611 and 4.585785/（kW-h） at limit values of turbine specific cost band intervals of 1000 and 1600 S/kW. It was further shown that Lagos, having the highest accumulated power outputs of 430.10kW/a from DeWind D7 at 70 m hub height, is the most preferred for economically usable power generation in terms of the levelized unit cost.展开更多
