Lignite cannot be transported for a long distance due to spontaneous firing nature of lignite. Further, Lignite excavated from NLCIL Mines is not exported nor lignite from other countries is imported.
(c): NLCIL is implementing the following projects to augment its lignite production:
i. Expansion of Mine-I (Area Expansion) & Expansion of Mine-IA from 3 MTPA to 7 MTPA, Neyveli, TN.
ii. Bithnok Lignite Mine(2.25 MTPA),Rajasthan.
iii. Hadla Lignite Mines (1.9 MTPA), Barsingsar, Rajasthan.
iv. Barsingsar Mine Expn (0.40 MTPA),Rajasthan.
v. Mine-III (11.50 MTPA), Neyveli, TN.
vi. Palayamkotai & South of Vellar (11.50 MTPA), TN.
(d): The total quantity of lignite (thermal grade quality) supplied to the thermal power stations during the last three years are as below
