Indian billionaire Gautam Adani and Anil Ambani's firm, Reliance Power, are considering bidding for coal-fired power plants being auctioned by the Indian bankruptcy court. If Adani wins the auction, it will add to the conglomerate's growing portfolio of coal power projects, which is seen as a way of recovering from a recent short-seller attack. Reliance Power's consideration of bidding for the asset is to win back control of the firm.
