Coal secretary Anil Swarup had previously indicated that next financial year onwards, government-owned power plants would go for 10 per cent domestic coal and private players will be encouraged to use more local fuel.
This financial year, realisations so far have been 22 per cent higher than the notified price. Last financial year, realisations were 33 per cent higher than the notified price.
"But, the situation is changing now. The coal stocks both at Coal India and the power plants are coming down and with the global prices on a rise, we expect private power producers to buy more coal from the auctions," an official said.
Coal India is also offering discounts of 35 per cent for lower grades and 20 per cent for middle grades to power plants.
ICICI Securities said September e-auction volumes came in at 20.5 mt, with realisation of Rs 1,570 per tonne, which is down by 28.1 per cent year-on-year. Coal India accounts for 80 per cent of India's total coal production and has a domestic market share of 65 per cent.
