Wind energy is accepted as one of the most developed, cost-effective and proven renewable energy technologies worldwide to meet increasing electricity demands in a sustainable manner. While, onshore wind energy technologies have reached to a stage of mass deployment and have become competitive with fossil fuel based electricity generation with supportive policy regimes across the world, exploitation of offshore wind energy is yet to reach a comparable scale.
With 18,522 mw installed capacity of wind energy, India ranks 5th in the world as on January 31, 2013. Wind energy is the fastest growing renewable energy technology for generating grid connected power among various renewable energy sources.
The preliminary assessment along the coastline suggests that there could be potential to develop offshore wind energy along Tamil Nadu, Gujarat and Maharashtra coasts. Setting up of offshore wind energy demonstration projects depends upon firming of the wind resource, oceanographic studies, environmental impact assessment and various clearances required for such projects as well as the presence of a policy framework.
The present wind power installed capacity in the country is 19,051 mw whereas the nuclear power installed capacity is 4780 mw. As per information available in Central Electricity Agency’s website, nuclear power projects have generated 13.72 Billion units of electricity during April-August, 2012, whereas wind power projects have generated 18.91 Billion units of electricity during the corresponding period.
Depending upon functionality of different type of power plants, the wind energy contribution in terms of generation during peak windy season in Tamil Nadu is around 30 per cent.
