In India the generation of electric power through wind mills started in 1950 and by March 1993 about 2,900 wind pump sets has been installed in seven states of the country. At the beginning of the Eighth Plan the installed capacity of wind-based power generation was a mere 40 MW. This was raised to 900 MW by the end of the Eighth Plan and in the first year of the Ninth Plan (1997-98) another 70 M W has been created. Also, for the first time during 1997-98 India has exported a wind turbine and that too to Australia.
The total potential for wind energy in the country is estimated to be 20,000 mw. This estimate is based on the technology available during the mid- 80s. It is being reassessed in the light of new generation of wind electric generators, higher unit sizes and increased hub-heights. A wind speed above 10 km per hour is prevalent over parts of coastal region and on the river banks in Rajasthan, Gujarat, Maharashtra and Karnataka. Wind mills can be operated there to harness wind energy.
The present wind energy programme is aimed at the development of cost-efficient technology for harnessing the vast wind potential in the country. Wind survey projects are under various stages of implementation in 22 states of the country. Establishment of470 wind stations have been undertaken. Of these 251 stations have become operational in 13 states as on March 1992.
The Central Government is considering the World Bank Master Plan to create wind power plants of 640 mw in Andhra Pradesh and 700 mw in Tamil Nadu. Asia's largest wind farm of 28 mw capacity is located at Lamba in Gujarat. Commercial projects of 920 mw capacity have been set up by the end of March 1998 mainly in Tamil Nadu, Gujarat and Andhra Pradesh.
