Abstract
Description
The study presents the wind energy potential (WEP) for six locations in Cross River
State, Nigeria. The objective of the study was to assess the WEP of the selected sites
for electricity generation, using small size wind energy conversion systems (WECs).
The wind data were measured at 10 m height and ranged from 4 to 10 years.
Additionally, the data were evaluated using the two-parameter Weibull function. Results
obtained show that annual mean wind speed, vm, and Weibull parameters k and c range
from 3.21 to 4.55 m/s, 3.32 to 6.69 and 2.99 to 5.40 m/s, in that order. The cost per kWh
of energy for the selected WECs fluctuated between 0.0626 ≤ COE ≤ 0.1375 USD/kWh,
while the avoidable CO2 emissions exist between 0.64 and 38.21 tons/year. However,
the probable savings made from diesel was not greater than 14,524.94 litres/year for
the locations with high WEP for small-scale stand-alone applications.
