Abstract
Wind energy powered pumps could be an alternative to conventional fuel powered
pumps for water abstraction because they rely on a free energy and they are environmentally
friendly. The objective of this study was to assess the potential of wind energy to operate water
abstraction systems in Teso sub-region of Uganda for livestock watering Daily mean wind speeds
recorded at a height of 10 m for a period of ten years (2005-2015) were collected from Amuria and
Soroti Meteorological stations in the study area. Data were analyzed using Weibull distribution to
evaluate the annual wind speed frequency distributions and consequently assess their potential for
water abstraction. The results indicated that warmer months (January, February and March) have
higher mean wind speeds than the cold months (August, September and October). High wind
speeds in the dry seasons corresponded to the periods of high water demand. The highest shape
parameter (k) of 3.07 was registered in 2009 and scale parameter (c) of 3.78 in 2012. The highest
wind power density of 43 W/m2 was obtained the year 2012 while the lowest wind power density
of 15.47 W/m2 was obtained for Soroti district in the year 2009. The maximum power extractable in
Amuria in 2012 was 324 W/m2 which is potentially enough for water abstraction. Maximum
discharges of 1.86 m3/s and 1.52 m3/s were obtained for Amuria and Soroti districts respectively at
mean wind speeds of 5 m/s. Therefore, Teso sub region winds have potential for water abstraction
and Amuria district better sites for livestock watering using wind energy.
