*Coal supplied under Memorandum of Understanding (MoU) on best effort basis.
Coal linkages have also been granted for 50% of the installed capacity of Uppur Super Critical TPP
(2 x 800 MW); Udangudi Stage-I (2 x 660 MW); Ennore SEZ (2 x 660 MW) of TANGEDCO/
TNPGCL and to develop Ennore TPS Expansion (1 x 660 MW) of TNPGCL.
(b): The supply of coal to the power plants including TNPGCL is a continuous process. Coal supply
is continuously monitored by the coal companies, power companies and by an Inter-Ministerial Sub-
Group comprising of representatives from Ministry of Power, Ministry of Coal, Ministry of
Railways, Central Electricity Authority (CEA), CIL and SCCL which meets regularly to take various
operational decisions to enhance supply of coal to Thermal Power Plants. The meetings of the Sub-
Group Committee are attended by the representatives of the power plants including TNPGCL. Based
on the requirement and the coal stock position, allocation of rakes is recommended by the Sub-
Group. The Sub-Group closely monitors rake allocation and movement to maintain supply
continuity. Logistical interventions by coal companies and the Sub-Group, undertaken in
collaboration with Railways, ensure allocation of sufficient railway rakes to the power plants of
TNPGCL as well as faster coal movement from coal mines to its power plants, thereby reducing
transit delays & ensuring steady plant operations.
(c) & (d): With regard to coal allocation adjustments, the coal linkage granted earlier for 50% of the
installed capacity of TNPGCL Ennore TPS Expansion (1 x 660 MW) has been surrendered by
TNPGCL. Further, on request of TNPGCL and recommendation of Ministry of Power, coal linkage
has now been earmarked to the State of Tamil Nadu for the entire capacity of 660 MW to develop
Ennore TPS Expansion (1 x 660 MW) of TNPGCL.
As regards quality of domestic coal, TNPGCL raised the issue of higher percentage of ash content
in domestic coal while for imported coal, TNPGCL has not faced any quality issue. To address
quality issues in domestic coal, the coal companies place special emphasis on quality management
to enhance customer satisfaction. Following measures have also been taken by coal companies under
the guidance of Ministry of Coal to improve the quality of coal: -
(i) To address the concerns of coal consumers regarding the quality of coal supplied by the coal
companies, a Standard Operating Procedure for Third Party Sampling & Analysis of coal at the
loading end was issued by Ministry of Coal on 26.11.2015. Sampling of coal at the loading end
is conducted through Independent Third-Party Sampling Agencies (TPSAs). The consumers are
free to engage any of the empaneled agencies.
(ii) First Mile Connectivity (FMC) Projects, equipped with rapid loading systems for improved
coal blending, dispatch of less than 100 mm coal and to maintain coal quality consistency have
been undertaken by coal companies.
(iii) Consumer Grievance Redressal - All quality related complaints received through consumer
grievance portal are addressed promptly.
Due to a continuous emphasis in ensuring supply of declared quality of coal, the overall final grade
conformity (including referee results) of coal supplied by Coal India Limited has steadily improved
from 62% in FY 2015-16 to 85% in FY 2025-26 (till 30.06.2025)
