  1. 1. Presentation onManagement of EnvironmentNational Thermal Power Corporation (NTPC) Robert S. Kharat, Roll No.156 Seema Nare, Roll No.159 Saroj R. Panigrahi, Roll No.160 Rajesh M. Salgaonkar, Roll No.164 1
  2. 2. NTPC 2
  3. 3. Vision : “To be the world’s largest and best power producer, powering India’s growth.” Mission : “Develop and provide reliable power, related products and services at competitive prices, integrating multiple energy sources withinnovative and eco-friendly technologies and contribute to society.” 3
  4. 4. NATIONAL ENVIRONMENT POLICY & ENVIRONMENT MANAGEMENT SYSTEM (EMS)• For NTPC, the journey extends much beyond generating power.• Right from its inception, the company had a well defined environment policy.• Committed to sustainable growth of power rather than generating power. 4
  5. 5. • First public utility to bring out a comprehensive document entitled "NTPC Environment Policy and Environment Management System“ in 1995.• Harmony between man and environment is the essence of healthy life and growth.• Importance of maintenance of ecological balance and a pristine environment .• Also participated to draft National Environment Policy. 5
  6. 6. Guiding principles adopted by NTPC• Pro-active approach to environment ;• Optimum utilisation of equipment ;• Adoption of latest technologies ;• Continual environment improvement ; 6
  7. 7. • Efficient utilisation of resources, thereby minimising waste, maximising ash utilisation ; and• Ensuring a green belt all around the plant for maintaining ecological balance. 7
  8. 8. SALIENT FEATURES • Achieve and maintain a leaders role in the area of Environment Management. • Adopt ways and means for Environment Protection and Environment Improvement. • Adopt sound Environment Management practices. • Aim at full compliance with the statutory norms / requirements. 8
  9. 9. Environment Management, Occupational Health andSafety Systems :• NTPC has adopted the best international practices on environment, occupational health and safety areas.• Pursued the Environmental Management System (EMS) ISO 14001 and the Occupational Health and Safety Assessment System (OHSAS) 18001 at its different establishments.• As a result, all NTPC power stations have been certified for ISO 14001 & OHSAS 18001 by reputed national and international certifying agencies. 9
  10. 10. Pollution Control Systems : • NTPC complies with all the stipulated environment norms, following state-of- the-art pollution control systems / devices have been installed to control air and water pollution: 10
  11. 11. Pollution Control Systems :• Electrostatic Precipitators • Ash Water Recycling System• Flue Gas Stacks • Dry Ash Extraction System• Low-NOX Burners • Liquid Waste Treatment• Neutralisation Pits Plants & Management System• Coal Settling Pits / Oil • Sewage Treatment Plants & Settling Pits Facilities• DE & DS Systems Cooling • Environmental Institutional Tower Set-up• Ash Dykes & Ash Disposal Systems 11
  12. 12. Additional measures taken in the area ofEnvironment Management :• Environment Management during Operation Phase• Monitoring of Environmental Parameters• On-Line Data Base Management• Environment Review• Upgradation & Retrofitting of Pollution Control Systems• Resources Conservation• Waste Management• Municipal Waste Management• Hazardous Waste Management• Bio-Medical Waste Management• Land Use / Bio-diversity• Reclamation of Abandoned Ash ponds• Green Belts, Afforestation & Energy Plantations 12
  13. 13. Ash Utilisation : • Sustainable ash utilization is one of the key concerns at NTPC. • The Ash Utilization Division (AUD), set up in 1991, • Maximum usage from the vast quantities of ash produced at its coal based power stations. 13
  14. 14. • The fly ash generated is used in manufacture of Cement, Concrete, Concrete products, Cellular concrete products, Bricks/blocks/ tiles etc.• Facility for loading fly ash into rail wagons has been provided so that fly ash can be transported in bulk quantity through railway network.• Ash Utilization level has reached from meagre 0.3 million tonne in 1991 - 1992 to 26.03 million tonne in 2010-11. 14
  15. 15. Sewage Treatment Plant :• TREATED SEWAGE WATER IS USED IN HORTICULTURE 15
  16. 16. Afforestation : • Undertakes afforestation programmes covering vast tracts of land in and around its projects in a concerted bid to counter the growing ecological threat. • Continuous vigilance is maintained to minimise pollution. • Developed independent Horticulture Department at its projects headed by experienced horticulture officers / supervisors. 16
  17. 17. Centre for Power Efficiency & EnvironmentalProtection (CenPEEP) : • Established Centre for Power Efficiency & Environmental Protection (CenPEEP) with a mandate to reduce Greenhouse Gas (GHG) emissions per unit of electricity generated by improving the overall performance of coal-fired power plants. 17
  18. 18. • Centre functions as a resource centre for acquisition, demonstration and dissemination of state-of-the-art technologies and practices for performance improvement of coal fired power plants for the entire power sector of India.• Balances the dual objectives of reducing carbon-di- oxide emissions that contribute to climate change and facilitating higher efficiency of power generation. 18
  19. 19. Monitoring of Environmental Parameters :• All pollutants discharged from the Power Plants such as stack emission, ash pond effluent, main plant effluent, domestic effluent and Condenser Cooling Water (CCW) effluents are monitored at the stipulated frequency at the source itself and at the points of discharge.• Ambient air, surface water and ground water quality in and around NTPC plants are regularly monitored to assess any adverse impacts as a result of operation of the power plant.• Developed and installed a computerised programme called “Paryavaran Monitoring System” for reliable storage, prompt and accurate flow of information on environmental performance of Stations.• Periodic Environmental Reviews. 19
  20. 20. Conclusion : • NTPC has adopted a pro-active approach to environment, optimum utilisation of equipment, adoption of latest technologies and continual environment improvement. • The policy also envisages efficient utilisation of resources, thereby minimising waste, maximising ash utilisation and ensuring a green belt all around the plant for maintaining ecological balance. • Excellent monitoring system which helps in compliance with the environmental norms. 20
