"...Aluminium capacity is currently at a surplus compared to consumption. However, the utilisation rates of the recently commissioned smelters would continue to be constrained by raw material and fuel availability issues, narrowing gap between demand and supply," said ICRA.
The government has kick-started the auction process for coal mines that were deallocated by the Supreme Court. It will put on offer 46 coal blocks and the auction of mines is due in February. Coal Minister Piyush Goyal recently said that over 100 bidders have already come forward to participate in the forthcoming coal mine auctions.
