In the second tranche of India's commercial coal mine auctions, a total of 34 bids have been received for 19 mines till now in states like Jharkhand and Chhattisgarh. Adani Group, Vedanta Ltd and Hindalco placed the bids, however, Aurobindo Realty & Infrastructure Pvt Ltd filed a maximum number of four bids.

As per the official statement by the Union Coal Ministry, "A total of 34 (thirty-four) bids have been received for 19 (nineteen) coal mines of which 10 (ten) are fully explored mines and 9 (nine) are partially explored mines."

The private players, who have placed the bids, have already completed numerous coal-related projects in the past, especially in Chhattisgarh and Jharkhand considering the immense coal reserves of the states.

In Chhattisgarh, Adani Enterprises had signed a pact with Maharashtra State Power Generation Co Ltd (MAHAGENCO). It was aimed to develop and operate the Gare Palma Sector II coal mine which has a total of 553.177 MT mineable reserves and the contract period is of 34 years.

Apart from Adani Group in Chhattisgarh, Vedanta's subsidiary BALCO is already managing Chotia Coal mine in Chhattisgarh since 2015. The mine, which largely contributes to fulfilling the state's thermal needs, has a capacity of 1 Million Tonnes Per Annum. Furthermore, earlier Aditya Birla Group's firm Hindalco also bagged Gare Palma IV/5 mine in the state which has an estimated extractable reserve of 42.43 MT.

In March 2021, the commercial auction of 67 coal mines was launched and the last date of submission of the Technical Bid was July 08, 2021. In the last 10 tranches, the Union coal ministry has offered 116 coal mines for auction which are highly contributing to meet the energy needs of various sectors. India's coal requirement is expected to go up to 1,123 million tonnes (mt) by 2023 and as of now, the country has the world's fourth-largest reserves.
