  11. Today ~39674 MW 2032 ~ 128000 MW Coal Gas Nuclear Hydro Renewables Planning for accelerated growth

  12. ELECTRICITY GENERATION SCENARIO

  13. India: Installed Power generation capacity 12 % 3 % 19% 66% Installed capacity : 209 GW RES :Renewable Energy Sources Status as of Oct 2012 Source : CEA

  14. Per Capita Consumption-Global scenario Values are in KWh

  15. Electric Power- Demand projections Source : Central Electricity Authority (CEA), India 1 GW(gigawatt) = 1O6 KW(kilowatt)

  16. The task ahead • India’s growing economy requires adequate supply of energy • Per capita consumption of electricity of 800 Kwh is lower than world average of 2200 Kwh • Energy deficit ~ (-7%) & Peak Demand Deficit ~(-9.4%) • T&D Losses ~ 25 to 50% • India’s installed electric power generation would have to increase to 861 GW by 2030 to sustain economic growth of 8-9%. • India needs to effectively tap all sources of Power Generation

  17. India’s Energy Resource Base 17

  18. Coal Based Power Installed capacity : 17624 MW Indian Coal Quality Issues with Coal based Power • High ash content (25-45%) • Low sulphur (< 0.5%) • Low calorific value~3000Kcal/kg • CO2 emissions • Ash disposal • Coal transportation bottleneck through rail Need for Clean Coal Technologies • Supercritical/Ultrasupercritical • Integrated Gasification Combined Cycle • Carbon Capture & Sequesterization

  19. Impact Area Efficiency Improvement CO2 Reduction Affordability Supercritical Technology • 660/800 MW units planned for all future coal based projects • Parameters adopted • 247 kg/cm2 535/565 and 565/593 deg C • Supercritical technology mandatory for Ultra Mega Projects • Many more supercritical units in pipeline.

  20. Integrated Gasification Combined Cycle Gas Cleanup Combined Cycle Gasifier Raw Gas Clean Gas Coal Power • High efficiency ~ 43-45 % • Potential for achieving even higher efficiency ~ Using advanced class Gas Turbines( Up to 50 %) • Potential for Green House Gas(GHG) Reduction • Low water consumption: Since 2/3 of power is generated from Gas Turbine India pursuing demo project of 100 MW- Feasibility study done by Nexant USA through USAID

  21. Gas based power • Installed capacity – 18903 MW • Gas Availability for power generation to be enhanced. • Expanding gas pipelines/LNG terminals • Advanced class Gas turbines : Thermal efficiency of 60%
