To make sure that there is a continuous income generating from livestock production and small scale agricultural activities, the availability and amount of water supply is essential. Although the Ethiopian Electricity Power Corporation supplies electrical energy to consumers at low prices, extending the service to the remote area of the country may be costly. Due to its damaging effects on the environment and highly increased cost, use of diesel energy as the source power in remote areas is not recommended. Therefore, considering the global warming the most serious problem facing the global community, use of renewable energy is the best alternative energy solution. Therefore, in this research, a detail investigation has been made to determine the feasibility of using wind power for extracting well water in the Borena site for limited number of households. Six years wind data of Borena site and seven different sizes of horizontal axis small aero-generators have been considered for the study. Statistical analysis of the raw wind speed data has been carried out by using MATLAB R7.12 program. The results of the research shows, the Borena site has an average wind speed 4.8m/s and wind power density 73.8W/m2 at 25m, which is applicable for small wind turbines. Then, economic analysis is done to identify the most profitable wind turbine. Finally, the SkyStream 3.7 is feasible regarding its performance and profitability for extracting well water in the Borena site.enThermal Engineering StreamThesis
