Evaluation of Wind Energy Potential as a Power Generation Source in Chad

Abstract EN

Long-term wind speed data for thirteen meteorological stations, measured over a five-year period, were statistically analyzed using the two-parameter Weibull distribution function.

The purpose of this study is to reveal for the first time the wind power potentials in Chad and to provide a comprehensive wind map of the country.

The results show that the values of the shape and scale parameters varied over a wide range.

Analysis of the seasonal variations showed that higher wind speed values occur when the weather condition is generally dry and they drop considerably when the weather condition is wet.

It was also observed that the wind speed increases as one moves from the southern zone to the Saharan zone.

Although the wind power at each site varies significantly, however, the potentials of most of the sites were encouraging.

Nevertheless, according to the PNNL classification system, they are favorable for small-scale applications only.

A few stations in the middle of Sudanian and Sahel regions are found to be not feasible for wind energy generation due to their poor mean wind speed.

The prevailing wind direction for both Saharan and Sahel regions is dominated by northeastern wind, while it diverged to different directions in the Sudanian zone.
