National Thermal Power Corporation (NTPC) aims to be the world's largest and best power producer through reliable and competitive power generation using innovative eco-friendly technologies. NTPC has had a defined environment policy since inception and the first public utility to publish a comprehensive environment management document. NTPC pursues ISO 14001 and OHSAS 18001 certification and complies with environment norms through pollution control systems and additional green measures like afforestation. NTPC also maximizes ash utilization and has an excellent monitoring system to ensure compliance with environmental standards.

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. • 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. Guiding principles adopted by NTPC
• Pro-active approach to environment ;
• Optimum utilisation of equipment ;
• Adoption of latest technologies ;
• Continual environment improvement ;
6

7. • Efficient utilisation of resources, thereby
minimising waste, maximising ash
utilisation ; and
• Ensuring a green belt all around the plant
for maintaining ecological balance.

8. SALIENT FEATURES
• Achieve and maintain a
leader's 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. Environment Management, Occupational Health and
Safety 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.

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. 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. Additional measures taken in the area of
Environment 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. 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. • 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. Sewage Treatment Plant :
• TREATED SEWAGE WATER IS USED IN
HORTICULTURE
15

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.

17. Centre for Power Efficiency & Environmental
Protection (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. • 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. 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. 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.
