ABSTRACT

The economics of wind energy viability for electricity generation in Calabar, Nigeria is considered in this study. Also, presented was the avoidable CO2 emissions, and diesel saved for utilizing wind energy. Wind characteristics were considered using the two way Wilbur parameter with wind data obtained from 1987 to 2007. The yearly average Weibull parameters k and c obtained ranged between 1.656 ≤ k ≤ 2.028 and  4.452 ≤ c ≤ 6.447 m/s while the power density (PD) and annual energy (AE) were between 119.83 ≤ PD ≤ 177.76 W/m2/year and 1048.77 ≤ AE ≤ 1554.75 kWh/m2/year at 10 and 30 m respectively. The lowest cost per kWh of energy was achieved using WECS-4/500 kW that varies from 0.0201 to 0.0459 $/kWh for the three specific cost of WECS.  Payback period (PBP) and Benefits cost ratio (BCR) analysis indicate all the considered WECSs were economically feasible for installation. Conversely, WECS-4/500 kW was nominated for Calabar, due to low PBP of 5.05 years with highest BCR of 1.345.



Keywords: Viability, Wind energy, CO2 emissions, Weibull parameters, Calabar
