In this project three consecutive years wind speed data measured five times a day forrnmore than thirteen stations from NMSA is used to predict the wind distribution pattern ofrnthe country. Based on the day time data, the most probable night time data is generatedrnusing appropriate software (HOMER), hence year round hourly data is generated for allrnstations along with statistical wind distribution model weibull shape and scalernparameters. Based on the wind potential assessment, wind pumping feasibility is done forrnwater supply and irrigation for a hypothetical model community at three differentrnlocations having similar topography as that of the representative sites. For pre determinedrndaily water demand and varied water well depth, wind pump sizing is done for eachrnapplication.rnFollowing the technical feasibility, economic analysis is done to compare with that ofrndiesel pumping system. Cost analysis model is prepared using excel, in which systemrnsizing and cost estimation are done. The life cycle cost, break even and unit water cost atrndifferent delivery head for pre determined daily flow rate is calculated based on givenrnfinancial parameters for both systems. The unit water cost for wind pumping and dieselrnpumping at typical delivery head of 20m for mekele, Jijiga and Assosa are found as 5.66,rn6.71 and 7.01birr/mrn3rn. Inrnaddition breakeven for wind pumping at typical delivery head of 20m occurs 1.9 yearsrnafter the system becomes operational. Hence, the result shows that wind pumping isrnfound to be more economical for water supply and irrigation than diesel pumping forrnstations having average wind speed 2.5m/s and above in the critical month.rnrespectively, where as diesel pumping costs 25.10birr/mrn3rnIn general at low hydraulic load wind pumping is best economical than diesel pumpingrnfor monthly average wind speed 2.5m/s and greater in the critical month. In this regard,rnthe country wind potential assessment shows average monthly and annual wind speedrnabove 2.5m/s is found extensively in Ethiopia, which strengthens the feasibility of windrnpumping in the country.
