The Comptroller and Auditor General of India (CAG) has asked state-owned power producer NTPC Ltd and Coal India Ltd (CIL) to resolve the Rs. 2,500 crore payment dispute over fuel supply and avoid an accounting nightmare. India’s largest power generation utility has argued over the poor calorific value of coal being supplied by Coal India. NTPC has claimed that CIL supplied them coal with a calorific value of 3,500 kcal per kg. instead of 5,000 kcal (kilocalorie) per kg calorific value. Due to this the power major has held back payment to Coal India.The plan was to resolve this contentious issue within the current financial year. The issue is not yet resolved and both the PSUs are running out of time.
