India is a highly populated developing country. Fresh water has become a scarce commodity in most parts of the world. The total water resource available in India is only 4% of the world’s fresh water resources. The domestic water requirements are projected to increase by more than 50%. Desalination could be a feasible solution to overcome fresh water scarcity. But the high capital cost and large power requirement are the problems faced and wind power is not utilized properly in India, because of the problems with integration of grid .This paper suggests non-grid wind power to supply the desalination unit for effective utilization of the wind power to increase the number of desalination units in India . This paper analyses the feasibility of wind forms in south East coastal regions of Tamilnadu and Puducherry.

Keywords: Desalination, dc drive , grid problems, water scarcity, wind speed analysis
