NEW DELHI: State-owned Coal India (CIL) on Wednesday said coal grade slippage in the third quarter of the ongoing fiscal was down to 34 percent and clarified that provisional bills of customers later get adjusted once the actual quality of coal is tested.
Grade slippage implies that the fuel’s grade during the sampling is found inferior than the declared grade.
CIL’s coal is divided into 17 grades. Each grade of coal depending on its heat content is assigned a Gross Calorific Value (GCV).
