Coal India Limited (CIL) is seeking prospective renewable energy buyers for the offtake of power from its 4.5 GW portfolio on a long-term basis at a fixed tariff. This capacity comprises 2.5 GW to 3.0 GW of solar and 1.5 GW to 2.0 GW of wind energy.

It will be supplied to the nearest interconnection point of the Inter-State Transmission System (ISTS) network.

CIL, the world’s largest producer of coal, plans to develop 4.5 GW capacity in a phased manner, ensuring the development of these projects on suitable land it will identify. The company will also be responsible for securing grid connectivity and issuing an EPC contract.
