Wages of non-executive workers, who account for 94 per cent of CIL’s workforce, are revised every five years.Notified coal prices were last revised by CIL in January 2018. The increase back then was effectively 11 percent. For 2025-26, the PSU has set a production target of 1 billion tonnes.The hike in coal prices is now likely to have an impact on India’s power tariffs as well. Coal-fired electricity contributes anywhere between 73-77 percent in meeting India’s power demand, which is growing at about 6.4 percent annually.
