GMR Energy, the power generation arm of the Rs 4,500-crore GMR Infrastructure, is raising Rs 465 crore from a consortium led by IDFC Group for its energy expansion plans. Argonaut Ventures and Ascent Capital are the other investors in this round. This funding comes hardly a month after GMR Energy raised $200 million (Rs 940 crore) from Temasek. The funds from the IDFC Group-led investors will support the company in expanding its power generation capacity.
