Description
Two commercial wind turbines namely AN Bonus 300 kW/33 and AN Bonus 1 MW/54 were technically
assessed for electricity generation in six selected high altitude sites spreading across the
North-West and North-East geopolitical regions of Nigeria by computing their capacity factors,
annual power and energy outputs. The economic evaluation of using the two wind energy conversion
systems (medium and large) for electric power generation in the selected locations were also
estimated using the present value cost method. The results showed that capacity factors of the
two turbines in the selected sites ranged between 4.6 and 43%. Average minimum cost per kW h was
obtained in Kano as $0.0222/kW h with AN Bonus 1 MW while the highest average cost is
$0.2074/kW h with AN Bonus 300 kW in Kaduna. The highest cost in each of the location was
obtained with the medium WECs (AN Bonus
300 kW). In addition, Kano and Katsina were also found to be very economical for any of the
adopted wind turbine models. Gusau and Kaduna, at cost of unit energy of about $0.30/kW h were
found to be more profitable for non-connected electrical and mechanical applications (water
pumping, battery
charging) than diesel generator.
