Bangladesh

The long term wind flow, especially in the islands and the southern coastal belt of Bangladesh indicate that the average wind speed remains between 3 and 4.5 m/s 5 for the months of March to September and 1.7 to 2.3 for remaining period of the year. There is a good opportunity in island and coastal areas for the application of wind mills for pumping and electrification. But during the summer and monsoon seasons (March to October) there can be very low pressure areas and storm wind speeds 200 to 300 kmph can be expected. Wind turbines have to be strong enough to withstand these high wind speeds.
