Coal India will set up 15 washeries across the country by October 2017 following which coal with more than 34 per cent ash content will be washed and then supplied to consumers.

"The process of setting up the washeries is well on track. Construction has started at several locations," Coal Secretary, Anil Swarup said on Wednesday.

Swarup was speaking at an event to launch the Contract Labour Payment Management System portal.

The portal will provide transparency on salary payments of Coal India's contract workers. Contract workers will also get to know the number of days they worked so that that they can quickly rectify any discrepancies.

Piyush Goyal, Minister of State (Independent Charge) for Power, Coal and New & Renewable Energy, said that in the current financial year, his ministries plan several more web-based applications to bring transparency in its functioning.

"We are going to launch an app for monitoring the bidding for solar power capacity, one will be for monitoring the transmission capacity and finally there will be one to monitor the coal linkages," said Goyal.

He also distributed a letter of appreciation to several public sector and government employees of the three ministries.
