Future of wind energy in india

  1. 1. FUTURE OF WIND ENERGY IN INDIA By: Dr Manoj Kumar Bhambu
  2. 2. FUTURE OF WIND ENERGY IN INDIA  Demand for energy is bound to increase with the increased economic development in the country.  Indian economy is reviving (7.4% in 2014) after sluggish growth in the last three years (6.6%, 5.1% and 6.9% for 2011, 2012 and 2013 respectively) (The World Bank, 2015).  It is expected to grow at faster pace in the times to come as Government of India is stressing upon “Make in India”, “Ease of Doing Business” and “Digital India” predominantly besides land and labour reforms.  It will further push the demand of electricity in almost all the sectors i.e. household, agriculture, commercial, institutional and industrial sector.

  4. 4. WHY RENEWABLE ENERGY?  The International Renewable Energy Agency (Irena) revealed that increasing Wind and Solar power sources to 36 percent would bring the goal of reducing greenhouse gases significantly closer(Gifford, 2016).  As Solar and wind energy can play a vital role in supplying clean and green energy;  Present paper tries to find out the role wind energy can play in the generation mix of power sector in India.  It tries to estimate the total production of wind energy by 2050 in India.

  6. 6. WIND ENERGY POTENTIALS OF INDIA  The National Institute of Wind Energy, formerly the Centre of Wind Energy Technology, recently announced that the total onshore wind energy potential in the country is 302 GW (determined at a hub height of 100 meters).  The fresh estimates are six-times the wind energy potential determined at a 50 meter hub height, and three-times the potential estimated at a hub height of 80 metres.  Of the total estimated 302 GW potential, 153 GW is available in wasteland, 146 GW in cultivable land, and 3 GW in forest land. (Mittal, 2015)  “The new Berkeley Lab study has found the total techno-economic wind potential to range from 2,006 GW for 80-meter hub heights (an indication of how high the wind turbine stands above the ground) to 3,121 GW for 120-meter hub heights,” an LBL news release states. (Shahan, 2012).  Only 25% of potential realisation gives us an opportunity as big as double the present total installed capacity. This shows the huge potentials in wind energy in India.

  10. 10. BASIC ASSUMPTION FOR ESTIMATING THE FUTURE OF WIND ENERGY IN INDIA  Past experience shows that size and wind turbine capacity is doubling every five years and with the increased hub heights it may slightly slows down but keep on increasing with steady pace. We can expect wind turbine of 20MW by 2030 and 40MW by 2040 and 60MW by 2048.  Average life-cycle for Technology is assumed to be 15 years and gradual shift in technology is assumed.  25 years of average life of a wind turbine is assumed hence total installed capacity is adjusted for decommissioning of old turbines.  It is assumed that number of new wind turbines installed will expected to rise at the rate of 5% and a factor of 10% uncertainty is increased after every five year for arriving at moderate scenario.
  11. 11. CONCLUSION  Wind energy has bright future and we can expect 30% contribution of wind energy in the total generation mix of electricity in India by 2050.  Though wind energy has its own negatives like noise and loss of birds life yet concentrating on off-shore potentials development and development of bladeless windmills that are having no visibly moving parts and reduced noise will solve these problems in coming decades.
