Reliance Power, the flagship company of the Anil Ambani group, plans to expand four large coal-fired power projects by 50% to generate an additional 8,000 MW of power. The company will scale up three ultra mega power projects of 4,000 MW each at Sasan, Krishnapatnam and Tilaiya. Similarly, it will expand the Chitrangi plant in Madhya Pradesh, for which Reliance Power plans to use coal from mines dedicated to the Sasan project. The company has already applied for environment clearance for additional 1980 MW in Sasan and plans to seek approvals for the rest.
