  1. Wind Energy: An Overview Presentation by Rakesh Kacker September 12, 2007

  2. Worldwide… Developments • Nearly 74,000 MW of wind power capacity has been installed all over the world • There has been 29% average annual growth between 1997-2006 and a ten-fold increase during this period • At the end of 2006, Germany had the highest installed capacity of 20,622 MW followed by Spain(11,615 MW), US (11,603 MW) and India (7000 MW)

  6. Worldwide… Drivers • The IPCC Report of 2007 has created great concern across the world on the issue of climate change • It calls for immediate action as against urgent action to arrest and counter GHG emissions • Wind Energy is the only technology that can offset CO2 emissions on a utility and even national scales • After the IPCC report, governments all over the world have come under pressure to promote wind energy projects through suitable mechanisms • Energy security is a matter of concern for most of the developed countries • Oil price hike in recent times, political developments in mid-east and gas crisis in the winter 2006-07 have further heightened the energy security concerns, particularly in Europe • Energy Security is an equally important issue in the developing countries like India and China • Wind Technology has become commercially viable

  7. Policy Mechanisms • All over the world there are policy support mechanisms for windpower development • Production Tax Credits • Renewable Portfolio Standards • Feed – in - Law • Tariffs in India

  8. Wind Energy Development – India • Wind Power Potential in excess of 65,000 MW • 7082 MW set up by March 2007 • Power and energy shortages, RPS regime the main drivers for wind projects • High industrial tariff is another reason • A target of 10,500 MW of capacity addition from wind has been proposed till 2012 for the 11th five year plan of the Government of India. • Freezes energy cost over a time horizon of 20-30 years • Modular – can be set up on scales of 1-200 MW • Short gestation period - 200 MW in six months • No uncertainties associated with fuel and its price • No fuel linkage, no fuel supply infrastructure • Clean energy with no adverse environmental effects • Additional revenue stream from CDM

  13. 80% accelerated depreciation allowed for investments in wind energy Section 80 IA benefits – Power Generation cos. are exempt from payment of any tax for a period of 10 years under section 80 IA of the income tax Act. Electricity generated by the wind farm allowed to be wheeled to designated industrial unit State Electricity Regulatory Commissions (SERCs) orders on renewable portfolio obligation in place Tariff order of the SERCs for purchase of electricity from a wind source in place India…Policy Environment

  15. Policy Issues • Enforcement Mechanism for RPS • Perception that Renewables are more expensive • Perceived burden of developing renewables is on the renewable rich states

  16. Regulatory Issues • Cost plus tariff setting – lack of any other alternative • Wide variety in regulatory regimes in different states • Sharing of CDM benefits

  17. Market constraints • Shortage of turbines • Difficulties in getting suitable land • Grid connections – intra state and inter state • Reliable data on wind resources • Small wind turbines

  18. What is the true potential? • 45,195MW estimated by MNRE in 2002 • Of this only 12875 MW feasible based on 20% grid penetration • Tamil Nadu has already done 3500 MW as against Gross potential of 3050 MW and Net potential of 1684 MW

  19. Why we need to grow faster • Assuming 45,000 MW as the potential, an average of 22% capacity utilisation, marginal cost of electricity at Rs. 5.50 per unit and marginal cost of wind power at Rs 3.50 per unit • Loss per annum is Rs. 14,000 crores
