Wind power generation scale mapping of Bangladesh at different turbine heights

Due to unimpressive prospect of fuel cell, geothermal, tidal and wave resources, wind energy is a major renewable energy source in Bangladesh along with solar and biomass energy. Bangladesh has a projected electricity demand of 10283 MW by the end of the year 2015, only 100 MW of that huge demand is projected to come from wind power sources, most of which is planned to be deployed in the coastal area and islands. But there are other places of interest for wind power generation, which could be good means for solving the huge power crisis. In this paper, feasibility of different scale of wind power generation at 35 different places is studied in perspective of Wind Power Density (WPD) at different turbine heights. All 35 sites attain power class 1 at 50m height, whereas at 120m height only 5 sites are projected to attain a much larger WPD and achieve a power class of 2 or more and remaining 30 places still belong to power class 1. From WPD and mapped turbine's rotor diameter from wind power class it is found that, large scale wind turbine at Chittagong and Jessore, medium scale at Khepupara, and small scale at Cox's Bazar and Hatiya is feasible.
