TEDA catalyses renewable energy sector growth in Tamil Nadu
The Tamil Nadu Energy Development Agency (TEDA). nodal agency of the Ministry of Non-conventional Energy Sources (MNES) is a Tamil Nadu government undertaking to promote renewable sources of energy and energy conservation activities. It has been a major catalyst of the tremendous growth Tamil Nadu has made in the development of wind power.
How TEDA achieved it is explained in the following lines.
Wind resources assessment programme
Wind resources assessment programme aims at identification of high wind prone sites with an annual mean \\rind speed of 18km/h & above. TEDA has undertaken state-wide wind resource assessment programme right from 1986 with the funding assistance of Government of India (MNES) and Government of Tamil Nadu and with the Technical Assistance of Indian Institute of Tropical Meteorology, Bangalore.
Installed at 67 wind prone zones each covering 10 sq. km area, 39 zones were considered as viable for commercial exploitation and out of these 17 zones have been exploited.
Windmill for water pumping
The device is ideally suited for pumping water for drinking purposes and for minor and small scale irrigation. The programme of installation of windmills for water pumping is being carried out in Tamil Nadu on subsidy basis with the funding assistance of MNES & Government of Tamil Nadu. There are two types of windmills i.e. Gear Type and Non-Gear Type. For the year 2001- 2002, state subsidy of Rs. 20,000 each has been sanctioned for 8 nos. Windmill for water pumping over and above the central subsidy.
Aerogenerator
This devise is a stand-alone type generator. The electricity generated is stored in a battery set, so as to make use of the power conveniently for feeding to small loads ranging up to 4 kw. The programme of installation of aerogenerator is being carried out in Tamil Nadu with 80% MNES funding assistance. MNES / GoI has sanctioned 3 nos of 5 kw aerogenerators to the institutions during 19909-2000 and the work is completed. One application received for solar-wind hybrid system. DPR under preparation.
Wind power generation
The first wjnd farm with 10nos. 55 kw of wind electricity generators (WEGs) was installed on January 18, 1986 at Mullakkadu, Tuticorin. Ever since then Tamil Nadu has made rapid progress with major funding assistance from MNES and with the local cost shared by TEDA and TNEB equally. It has so far established demonstration wind farms at eight areas with a total capacity of 19.10 MW. As on 31-12-2001 these demonstration wind farms in Tamil Nadu with 117 wind electric generators have cumulatively generated and fed into electricity board grid a total of 312.5 million units of electricity.
Motivated by the success of the above government programmes, private sector has made rapid strides on wind power generation. The first private sector wind farm of the country was set up in Tamil Nadu during 1990 with two wind electricity generators of 250 kw each at Muppandal.
Added to this glory, the single largest area of private wind farms of the country is existing only in Tamil Nadu in Muppandal area with an installed capacity of 415 MW. This is next only to the cluster of windmills installed at California in the US.
These private wind farms with 2943 wind electricity generators and with a total installed capacity of 513.3 95 MW have generated and fed into the TNEB grid a total of 6342 million units of electricity up to 31-12-2001. Totally both public sector and private sector wind farms have generated 6 6 54.5 million units to the grid as 31-12-2001. Tamil Nadu as on date has the highest installed capacity in Indiain respectof wind electricity generation. i.e. a total of 832.495 MW against the national installed capacity of 1340 MW as on 31-3-2001.
Energy audit:
TEDA is co-ordinating with TNEB for implementation of energy audit in power-intensive HT industries in Tamil Nadu. An expert monitoring committee has been formed with representative from TEDA, TNEB, CEIG, to co-ordinate and monitor the scheme. The Government of Tamil Nadu has made the implementation of energy conservation measures mandatory in all HT industries (G.O Ms.No.72 of Energy (C2) Department dated 10-05-96) with HT power consumption with maximum demand exceeding 2000 kva under Phase I and between 1000 kva and 2000 kva under Phase II.
