    COAL SHORTAGE SCENARIO IN THE POWER SECTOR

    Shortage to be addressed through import

  • 7/30/2019 coal as fuel

    15/25

    Coal shortage envisaged due to:

    Long term linkage accorded on normative PLF

    of 68.5% and 80% for stations coming after1996, whereas the national average is +70%

    PLF. (some of the stations like those of NTPC

    operating at +90% PLF)

    Delay in development of linked mines

    COAL AVAILABILITY vis--vis SHORTAGE

    RESULT - NEED TO AUGMENT COAL AVAILABILITY

    Against the current demand of about 150 MMSCMD, supply is about

    92 MMSCMD only. Gas/RLNG availability and prices of available

    Gas/RLNG/imported piped natural gas are two major constraints for

    gas based power generation

    Fixed cost of Generation for coal based & Gas Based Plants are comparable.

    Thus,for Gas/R LNG to compete it has to be on fuel cost component basis

    OTHER INDIGENOUS FUELRESOURCES:LIMITATIONS

    Other resources like crude oil, coal bed methane,renewable energy sources etc. are meagre and notcapable of catering to our energy requirements in the

    long run. Gas and crude oil prices are volatile in the international

    market and coal import is a much cheaper option thanimport of oil and gas especially at coastal locations.

    Conclusion - Coal is likely to remain our mainstayfuel for energy generation till 2031-32. However,current shortage is a cause of concern.

    Coal Shortage The Way Forward

    Stepping up domestic coal production by allotting blocks

    to central and state public sector units and for captivemines to notified end users

    Coal Import needs creation of necessary infrastructure.Will also put pressure on domestic coal industry to be

    efficient. NTPC has imported about 3 million tes ofcoal in 2005-06.

    Amendment in Coal Mines Act to facilitate (a) privateparticipation in coal mining for purposes other than those

    specified and (b) offering of future coal blocks topotential entrepreneurs.

    Technology for economic exploitation of coal lying atgreater depths

    Issues of concern with the coal sector

    Pricing

    70% of the domestic coal is dedicated to powergeneration.

    Fuel cost constitutes about 65% of the total costof generation

    Since the dismantling of APM, coal prices havebeen taken for arbitrary escalation with notransparency

    The opening of the sector to private players willbring in competition and prices will be determinedby market dynamics

    Till such time, a regulatory mechanism needs tobe put in place to put a check on arbitrary price

    hike.

    Issues of concern with the coal sector: Contd

    Infrastructural Limitations- Burdened transportationnetwork - calls for following measures:

    Transportation capacity to be increased. Rationalization of linkages to cut down on

    transportation distance and better utilization of

    existing infrastructure

    Cut down on criss-cross rail movement Coastal stations to be run on imported coal

  • 7/30/2019 coal as fuel

    23/25

    Issues of concern with the coal sector: Contd

    Environmental Issues :

    More emphasis on use of washed coal

    Use of clean coal technology like IGCC

    Strict implementation of MOEF stipulations

    Proper restoration of degraded land due to open cast

    mining.

  • 7/30/2019 coal as fuel

    24/25

    Conclusion & Way Forward

    Coal shall remain mainstay for power generation in India.

    Allocation of captive blocks to end users.

    Allowing private participation

    This will also create a competitive environment and which will

    enable market driven pricing structure.

    Till such time, regulator to be put in place to ensure fair pricingof coal, proper development of infrastructure & efficient

    utilisation of resources in the coal sector.

    Keeping in view the longer gestation period of coal mines, faster

    clearances of coal projects needs to be undertaken so as to becommensurate with the commissioning of power plants.

    Coal washing and use of clean coal technology to be promoted.

    Transportation network bottlenecks to be reduced by judicious

    rationalization of linkages.
