RESULTS AND DISCUSSION

Wind potential analysis across agro-ciimatic zone confirms the role of geographic, topographic and meteorological characteristics of a location to wind speed variability. Table 2 lists locations in the respective agro-ciimatic zones with mean wind speed greater than 18kmper hour (i.e. >5 m/s) [4].Among these sites, wind energy generators totaling a capacity of 3.5 MWhave been functional since 1998-99at Chikodi. Figure 2 depicts monthly variations across Northern dry zone
