*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 SubGroup  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 SubGroup 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 SubGroup.  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)
