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.

National power objectives
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.

NTPC’s vision on climate change

“Going Higher on Generation, lowering GHG intensity”



Ntpc approach
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


Netra focus on research and new technologies

R&D DEPARTMENT FOR APPLIED RESEARCH

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.

Efficiency improvement through renovation modernization
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


NTPC Fuel Mix by 2017

Capacity mix - TODAY

(29,894 MW)

Capacity mix- 2012

(50,000 MW)

Capacity mix- 2017

(75,000 MW)


Renewable
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.


Distributed generation
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.


Green measures
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.


Conclusion
