  1. Climate Change and Power Sector NTPC Ltd.

  2. Role of Power Sector

  3. World Energy Scenario: Main Contributors of CO2 Emission 1973 2006 Gas 14.4 % Gas 19.4% Oil 38.5% Oil 50.6 % Coal 34.9 % Coal 41.7% 15640 Mt of CO2 28003 Mt of CO2 Source: IEA, Key Energy Statistics, 2008

  4. Primary Energy Supply Mix of the world 1973- 6115 Mtoe 2006- 11741 Mtoe Source: IEA, Key Energy Statistics, 2008

  5. World Power Generation- different modes 1973- 6116 TWh 2006- 18930 TWh Fossil Fuel based power generation constitutes the largest mode of power generation in the world and will remain so in the coming decades

  6. Power Generation Mix of India Coal is expected to remain the preferred fuel for coming decades. 64% of the 11th plan targets consists of coal based generation. Recent developments are encouraging for the nuclear fuel based generation. Nuclear Renewable Hydro Coal Oil & gas (Figures in MW) Source: CEA, Dec 2008

  7. National Power Objectives Ambitious Capacity Addition Plans • Power for all by 2012 • Per capita consumption of power to be increased to 1000 Units by 2012. • Min. lifeline consumption of 1 unit/ household/ day by 2012. • Accessibility of electricity by all households by 2012. Issue: How to develop strategies for rapid capacity addition without detrimental effects on the environment.

  8. NTPC’s Approach

  9. NTPC- Powering India’s Growth NTPC NTPC All India All India

  10. NTPC – AMONGST THE CLEANEST FOSSIL FUEL POWER GENERATORS SOURCE: CARMA.ORG: NTPC ANALYSIS* • Assumptions: • The largest generating companies with Annual generation above 150 BU • The companies having minimum fossil fuel mix of 50%

  11. NTPC’s vision on climate change “Going Higher on Generation, lowering GHG intensity”

  12. NTPC’s approach to climate change

  13. NTPC Approach • As a responsible Corporate Citizen, NTPC accords high priority to its responsibility towards Climate and Sustainability. • Investment in development of new technology through R&D and Energy Technology center. • NTPC sets aside up to 1% of its distributable profit for R&D including 0.5 % for technology initiatives for sustainable energy development. • Generation Capacity Expansion is complemented by Emission Mitigation Endeavours • Sustained effort to enhance plant efficiency • Suitably realign the fuel mix • Adoption of greener and eco-friendly technologies

  14. R&D DEPARTMENT FOR APPLIED RESEARCH ENERGY TECHNOLOGIES: WORKING ON 14 PROJECTS THROUGH IDENTIFIED INSTITUTIONS IN AREAS PERTAINING TO POWER PLANT EFFICIENCY IMPROVEMENT CARBON SEQUESTRATION WASTE HEAT UTILISATION, ETC ET AND R&D CENTRE BEING MERGED TO FORM NETRA (NTPC ENERGY TECHNOLOGIES RESEARCH ALLIANCE)TO ENABLE MORE FOCUS AND SYNERGISTIC RESEARCH INTEGRATED GASIFICATION COMBINED CYCLE (IGCC): NTPC IN COLLABORATION WITH BHEL IS IN PROCESS OF INSTALLING AN IGCC PROJECT IN AURAIYA. NTPC, IN ASSOCIATION WITH NEXANT, HAS DONE STUDY ON GASIFIER SUITABLE FOR INDIAN COAL. NETRA – Focus on Research and new Technologies 14

  15. Adoption of higher efficiency units 5.1% 3.0% Base 0.7%

  16. SUB CRITICAL SUPER CRITICAL ULTRA SUPER CRITICAL PLANT EFFICIENCY* 34 % 37% 41% FUEL CONSUMPTION BASE BASE - 8 % BASE - 17 % CO2 EMISSIONS (272,000 mg/nM3) 1008 926 835 gm/Kwh NOX EMISSIONS (650 mg/nM3)** 2.41 2.22 2.00 gm/Kwh SOX EMISSIONS (2,000 mg/nM3)** 7.43 6.82 6.16 gm/Kwh PARTICULATES (50 mg/nM3)** 0.19 0.17 0.15 gm/Kwh Higher Efficiency – Lower Emission ** Current World Bank Emission Guidelines * HHV Basis

  17. Super Critical Technology in NTPC NTPC adopted supercritical technology for unit size over 500 MW in steps as under: • PLANTS IN ADVANCE STAGE OF CONSTRUCTION • 3 x 660 MW Sipat STPP Stage-I • 3 x 660 MW Barh STPP Stage-I • UPCOMING PLANTS • Barh-II, Bihar – 2x660 MW (Order Placed) • North Karanpura, Jharkhand – 3x660 MW • Darlipali, Orissa – 4x800 MW • Lara, Chattisgarh – 5x800 MW • Marakanam, Tamilnadu – 4x800 MW • Tanda-II, Uttar Pradesh - 2x660 MW • Meja, Uttar Pradesh - 2x660 MW • Sholapur – 2x660 MW • New Nabinagar-3x660 MW • Many more projects under formulation

  18. Efficiency Improvement through Renovation & Modernization After 100,000 operating hours machine become due for R&M R&M offers a quick and low cost capacity addition and efficiency enhancement option. R&M objectives are: • Restoration, Sustenance & Enhancement of Efficiency • Capacity enhancement • Life extension of old units • Mitigate obsolescence • Compliance to applicable pollution norms • Equipment safety • Improvement in equipment / system reliability

  19. NTPC Fuel Mix by 2017 Capacity mix - TODAY (29,894 MW) Capacity mix- 2012 (50,000 MW) Capacity mix- 2017 (75,000 MW)

  20. Renewable • NTPC plans to add 1000 MW from renewable sources by 2017. • Recently signed MoU for 500 MW of wind power in Karnataka. • MoU with ADB for development of 500 MW from renewable sources. • NTPC has taken major initiatives for fast tracking its solar power development programme. • We hope to set up 15MW solar capacity by 2012 and 50 MW capacity by 2014.

  21. Distributed Generation • NTPC has commissioned 10 projects in off-grid distributed power generation mode based on bi-mass, solar PV, micro hydel etc in villages around projects. • Several others are planned as part of CSR activities. • There is also proposal for setting up mini hydel projects at several places in Punjab and North-eastern states.

  22. Green Measures • NTPC has created green wealth and carbon sink in the form of more than 18 millions trees planted in and around plant areas. • NTPC has started implementing modern water harvesting systems in all upcoming townships in the projects for better management of water. • NTPC is committed for development of 1 million Sq feet of green building space within NTPC premises. • Energy Conservation can also play a major role; NTPC has adopted practices like Online Energy Management Systems, Energy Audit, Water-balance Audit for main plant and BOP equipments. As per study conducted by National Remote Sensing Agency, Hyderabad, the summer peak temperatures in areas surrounding Ramagundam Thermal Power Station of NTPC where about 1.2 million trees have been planted, has reduced to the extent of 30 C.

  23. Conclusion NTPC stands committed for sustainable power development
