Abstract
In this study, wind characteristics and wind power potential are analyzed for three meteorological stations in the Sudanese zone of Chad for the period of 35 years (from 1975 to 2010). Assessment of the wind power potential was carried out using the two parameters of Weibull distribution. Results of the study shows that the average annual wind speeds at 10 m above ground for Moundou, Pala and Sarh are 2.69, 2.33 and 1.91 m/s, respectively. The mean annual value of the Weibull shape parameter k and scale parameter c range from 2.376 to 3.255 and 2.099 to 3.007, respectively. The maximum annual power density of 204.85 W/m2 was obtained at Moundou. Results of this study further shows that the selected locations are not suitable for large-scale wind energy production at 10 m altitude. However, by extrapolation, assessment of wind speed at 67 m altitude combines with wind turbine Vestas 2 MW/80 that adapts to the Sudanese local conditions, and the wind power potential can be exploited for water pumping, heating and production of electricity.

Summary
Energy plays a significant role in human and economic development. Demand for energy is growing exponentially. To satisfy this energy demand, it is necessary to embark on alternative sources such as renewable energies which are clean sources of energy and nonpolluting [6] [7]. The highest growth rate of wind energy was 64.3% and this occurred in 1999 It is recognized as the source of energy which develops most quickly on a worldwide scale. Chad is a country with 80% of her population living in rural area, without a particular grid system of electricity. To the best knowledge of the authors, there have been no much research works on assessment of solar and wind energy potentials in Chad. This study aims at assessment of the potential of wind energy in the Sudanese zone of Chad using Weibull distribution
