Abstract
Adama Woreda has good wind resource potential for grid based wind farm establishment.
But, selecting sites for wind farm in the study area is a complex process involving not only
technical but also physical, economical, social and environmental considerations. This study
focuses on mapping wind farm suitability in Adama Woreda. The major data used were
topographic map (1:50,000), Landsat image (2005), and GIS data layers such as roads,
towns, transmission line, geology, land use and slope. The factors were developed in the GIS
and Remote Sensing environment then weighted and overlaid by the principle of pairwise
comparison. Once the wind farm suitability map has been completed, sites were evaluated
with respect to the factors. The finding of this study shows that there is sufficient area for
wind farm establishment in Adama Woreda with the most suitable sites located in the
southeastern, northeastern and southern parts. 85% of the most suitable sites are laid on
agricultural land which is relatively compatible with wind farm. 38.5 and 21.24 % of most
suitable area are laid on recent aphyric basalts and ash flow tuffs respectively which are most
suitable and moderately suitable areas from engineering point of view.
