In the shift to sustainable electricity generation, wind energy has emerged as a key renewable energy source. However electricity generation by tapping into the kinetic energy of the wind is extremely sensitive to various factors including wind turbine’s blade design, blade mass and blade surface roughness as well as topography, geography and the environment of turbine installation vicinity. Coastal stretch of Sindh and Balochistan provinces have been identified as the wind corridor of Pakistan and all of the operational wind farms of Pakistan are sited in Jhimpir and Gharo regions of southern Sindh province. However, these regions are identified as arid-desertic in nature affected by various sorts of dust events such as dust/sand storms, dust in suspension, blowing/drifting dust, etc. with very high humidity and low precipitation levels. In this connection, a study has been designed and conducted to determine the extent of dusty nature of study region and evaluate the effects of dust on the electrical output of the wind turbine in Jhimpir against its theoretical or forecasted output. The study's findings indicate that there is a large percentage difference between theoretical and real output during the months that follow the months with greater dust activity. In addition, the dust accumulated over time, gradually increasing the percentage errors. Therefore, there is a need to take adequate measures and install custom made turbines in these types of regions which can bear the hardship of the seasons and environment to achieve optimal output.
