Achievements Tamil Nadu Electricity Board is a pioneer organization among the State Electricity Boards in India in promoting Renewable Energy Programme. Tamil Nadu is blessed with conducive natural metrological and topographical settings for wind power generation. Four passes namely Palghat pass, Shengottah pass, Aralvoimozhi pass and Cumbum Pass are endowed with heavy wind flows because of the tunneling effect during South west monsoon with an average wind speed of 18 to 22 Km/Hr. Initially during 1986, the first demo wind farm with 20 Nos. Wind Electric Generators each 55KW were erected at Mullaikadu in Tuticorin District, in association with Tamil Nadu Energy Development Agency (TEDA) under the aid of Ministry of Non Conventional Energy Sources (MNES), Government of India. Subsequently various windfarms were erected by TNEB at other places in Kayathar, Muppandal and Puliankulam areas including Kethanoor in Coimbatore. Totally 120 windmills were erected by TNEB from 1986 to 1993 totaling to a capacity of 19.355 MW. Based on the successful functioning of these demonstration wind farms, private developers had shown keen interest in this sector which has now led to an installed capacity of Private Wind Mills of about 7262 MW as on 31.05.2014 contributing to 34% of India’s total wind capacity . The Wind Electric Generators are installed in the Districts of Tirunelveli, Kanyakumari, Tuticorin, Ramnad, Coimbatore, Udumalpet, Dindigul, Theni, Tirupur and Erode. At present around 11,000 to 13,000 million units per annum are generated from the above windmills, contributing to about 14% of the yearly energy need of the State. Table - I Sl.
