Recently, faced with stagnated demand from the power sector, its key customer, Coal India has been using the auction route to clear its stock and earn better margins. During April-December, the company sold 64.7 million tonnes via the e-auction route, 41 per cent higher than what it sold during the same months of the previous financial year. However, sales volume from long-term fuel supply agreements dipped by 4.5 per cent to 313.5 mt in the same period.
