Under e-auction, coal is sold at spot market price.
Last year, Coal and Power Minister Piyush Goyal had asked CIL to reduce the quantity offered in e-auctions so that power utilities can get more supplies of the fuel.
The company was directed to limit e-auctioning of coal to 25 million tonnes in the last year from 57 MT.
However, according to the sources, in the last fiscal 49 million tonnes of coal was sold through e-auction as it was asked by the ministry to e-auction the surplus coal from those mines that have been facing evacuation constraints.
There has been a large accretion of coal during this peak production season at mines which have serious evacuation constraints, the ministry had said.
At the same time, coal needs to be made available to the FSA (Fuel Supply Agreement) holders on priority, it added.
Coal India has missed its production target for the financial year 2014-15 by 3 per cent and just achieved an output of 494.23 million tonnes.
