The document provides an overview of the Indian power sector and economics of wind energy in Tamil Nadu. It summarizes that Tamil Nadu has significant wind power potential and is a leading state in India for installed wind capacity. Wind energy is an important renewable source that can help meet India's growing energy demands in a sustainable manner. The economics analysis shows that wind energy projects in Tamil Nadu are financially viable due to available incentives and low operation and maintenance costs.

Overview of Indian power sector & economics of wind energy in Tamil Nadu
1. An overview of Indian power sector & Economics of Wind mill in Tamil Nadu Chairman Mr.K.Sekar MembersPresented by Dr.T.R.Shanmugam G.V.Venkatesh Dr.C.Chinnusamy
2.
3. Development of a country is highly correlated to per capita energy consumption.
4. Increasing population, modern civilization and technological advances contribute to increased consumption of energy.
5.
6. Wind energy is the fastest growing renewable energy.
7. Wind turbines are up to the task of producing serious amounts of electricity.
8. Wind energy has started making meaningful contributions to the overall power requirements of some States.
21. Tamil nadu Scenario Wind generation is the fastest growing energy source in this decade , expanding at 25% a year. Tamil Nadu is a pioneer State among all the states in India in promoting Wind Energy programme. Tamil nadu contribution is around 42 % of the country’s installed wind power capacity. Tamil Nadu is blessed with conducive natural meteorological and topographical settings for wind power generation.
22. Total Power Generation Capacity (MW) (As on 31st March 2010) Total Generation Capacity :15800.315 MW (Source : TNEB)
51. Other financial incentives/subsidies in certain states.Foreign Investment Policy: Automatic approval for foreign investors to enter into Joint Venture with an Indian partner for financial and/or technical collaboration/setting up of RE based power projects (100% equity permissible)

55. Estimate drawn up by the Infrastructure Development Finance Corporation (IDFC), each unit of electricity produced by wind power, could earn 15 paise worth of carbon credits.
56. As per a rough calculation, a 600/750 KW turbine can earn its O&M cost per year.
57. The ‘Prototype carbon fund’ of the World Bank encourages investor to fund renewable energy projects. Investors are given pro-rata share of the CERs produced from their investment.
60. Economics (Tentative) Cost of system - Rs.2.50 - 3.00 lakhs / kW. MNRE Subsidy for the system for 2007-08, up to 50% of Ex-works cost for individuals and 75% for community users subject to a maximum limit. (subject to change) Saves around 2500 kWh per kW per annum depending on wind speed and duration.
69. Wind Mill Water pump Ideally suited for pumping water for drinking purposes and / for minor irrigation. The wind speed is about 18 kmph. Gear-type wind mills are also available which can operate at a speed of 9 kmph. Types 1. Gear type and 2. Gearless type.
71. Economics (Tentative) Cost of system - Rs.1.50 to 2 lakhs. MNRE subsidy available for 2007 - 08 Rs.30,000/- per pump for Gear type and Rs.45,000/- per pump for AV55 Type (subject to change) Saves around 1500 kWh per annum depending on wind speed and duration.
