Abstract

The present study provides an assessment of micro-wind energy potential within the 170 districts in Ghana with more focus on a distributed electricity system for district household electrification. The wind resource is assessed based on three main potentials, the theoretical, the geographical and the technical; these included an assessment of localised wind power densities, necessary environmental conditions of the terrain suitable for wind turbine installation as well as the energy generated by the turbine within the districts. The study was done using wind speed data at a hub of 50 m and then interpolated to a 1 km by 1 km grid cell to enhance granularity and localisation of the geospatial assessment of results. All input datasets were interpolated to this effect. The study is based on a single turbine model; V52/850 and used its power curve to determine the maximum energy output per grid cell. Results of the analysis are visualised using high resolution maps. Results of the analysis show that, areas along the coast and the middle belt areas show high potential with annual production more than a 2,000 GWhy−1 per square kilometre.
