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

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.
