The renewable energy sources offer scope for power generation in dispersed mode and at the load points, thereby eliminating line loss. Moreover, they are eco-friendly and do not pollute the environment. Wind in India are influenced by the strong south-west summer monsoon, which starts in May-June, when cool, humid air moves towards the land and the weaker north-east winter monsoon, which starts in October, when cool, dry sir moves towards the ocean. During the period march to August, the winds are uniformly strong over the whole Indian Peninsula, except the eastern peninsular coast. Wind speeds during the period November to march are relatively weak, though higher winds are available during a part of the period on the Tamil Nadu coastline. This paper presents the analysis of real time wind measurement and the prediction of available wind potential in the 50 metre meteorological tower installed at Sathyabama University, Chennai, near east coastline of Tamil Nadu.
