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.

• 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.

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 RD and Energy Technology center.
• NTPC sets aside up to 1 of its distributable
  profit for RD 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

NETRA Focus on Research and new Technologies

• RD 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 RD 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.

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
