Abstract: The wind energy resource situation in Nigeria including the estimated potential, economic competitiveness, technical assessment, cost comparison of wind energy technologies with other energy technologies, available amount of the resource and global wind energy utilization are presented in this study. The status of the database is discussed indicating its degree of adequacy and an identification of the gaps. Wind speeds in Nigeria range from a low 1.4-3.0 m sec^-1 in the Southern areas and 4.0-5.12 m sec^-1 in the extreme North. Wind speeds in Nigeria are generally weak in the South except for the coastal regions and offshore locations. In Nigeria, peak wind speeds generally occur between April and August for most sites. Initial study has shown that total actual exploitable wind energy reserve at 10 m height may vary from 8 MWh year^-1 in Yola to 51 MWh year^-1 in the mountain areas of Jos Plateau and it is as high as 97 MWh year^-1 in Sokoto. Hence, Nigeria falls into the poor/moderate wind regime.
