NTPC Mining Limited (NML), a wholly owned subsidiary of NTPC Limited, has invited an Expression of Interest (EOI) for developing 50 MWp of ground-mounted solar PV projects at two of its coal mining locations. The initiative is aimed at supporting clean energy adoption and reducing the carbon footprint of NML’s mining operations.
The proposed solar capacity will be developed under the Renewable Energy Service Company (RESCO) model. Under this arrangement, the selected developer will finance, construct, own, operate and maintain the projects for 25 years. NML will purchase the entire electricity generated from the plants for captive consumption at a tariff determined through competitive bidding.
The first 25 MWp DC/20 MW AC project is planned at Overburden Dump-C of the Pakribarwadih Coal Mining Project in Hazaribagh district, Jharkhand. Around 80 acres of dump-top land has been identified for the project, with an expected execution period of 18 months. NML has indicated that the capacity could potentially be increased to 30–35 MWp during the subsequent Request for Proposal (RFP) stage.
The second 25 MWp DC/20 MW AC project will be developed at the MGR Bulb Area of the Talaipalli Coal Mining Project in Sundargarh district, Chhattisgarh. The project will use approximately 80 acres from the available 112-acre area and is expected to be completed within 15 months.
Both projects will require a minimum DC/AC ratio of 1.25 and a minimum Capacity Utilization Factor (CUF) of 22%. The EOI has been issued under reference NML/Engg/EOI/01, with the publication date set as August 11, 2026. Interested participants can submit clarification queries until August 18, while the deadline for EOI submission is September 1, 2026.
No Earnest Money Deposit or Performance Bank Guarantee is required at the EOI stage. These requirements and other commercial conditions are expected to be finalized during the formal RFP and Power Purchase Agreement process.
The EOI is non-binding and is intended to assess market interest, technical capabilities, commercial viability and industry feedback before NML proceeds with the formal tender. Eligible participants include Indian companies, firms, Central Public Sector Undertakings, State Governments, PSUs and consortiums comprising up to three entities.
NML has also reserved the right to restrict participation in the subsequent RFP to entities that submit responses to the current EOI. Applications must be submitted digitally through NTPC’s e-procurement portal.
