"Coal supply from Northern Coalfields Ltd (NCL) to Anpara (UPRVUNL), Anpara C (Lanco), Rihand and Vindhayachal (NTPC) is affected due to coal handling plant problem at Amlori, Nigahi, Jayant and Dudichua mines of NCL...These issues be resolved urgently so the coal supply to plant increases," the Power Ministry said in a document.
The Ministry further said that "materialisation" from Coal India (CIL) subsidiaries -- Mahanadi Coalfields Ltd (MCL) and -- South Eastern Coalfields Limited (SECL) -- is around 67 per cent and 87 per cent, respectively, resulting in low coal stock with most of the power plants situated in the southern and western regions.
Besides, there is low production of coal in Singareni Collieries Company Ltd or SCCL due to environmental stipulations, it added.
The development comes at a time when State-owned Coal India and NTPC are at loggerheads over quality of coal being supplied to the plants of the power producer.
