Abstract

Wrong wind site selection is the leading factor to the non-promising wind energy in Nigeria. Ten 0 0 years daily average wind speed data measured at 10m height for Sokoto (13.01 N, 5.7 E and 297m) obtained from Nigeria Metrological agency (NIMET) and characteristics of the three small scale wind energy conversion systems with power rating of 1, 1.5and 2.5 were used in this study to evaluate the performance of the selected wind energy conversion system (WECS). The annual energy output for the WECS were 2.79MWh, 2.86MWh and 3.76MWh and also the capacity factors 31.9%, 21.7% and 17.2% respectively. It is concluded that e3001 1kW is best suited among the three selected WECS for the location.
