NTPC Mining Limited (NML), a wholly owned subsidiary of NTPC Limited, has invited an Expression of Interest (EOI) for the development of 50 MWp of ground-mounted solar PV projects at two of its coal mining locations in Jharkhand and Chhattisgarh. The initiative aims to promote clean energy adoption and reduce the carbon footprint associated with NML’s mining operations.
The proposed projects will be developed under the Renewable Energy Service Company (RESCO) model, under which the selected developer will be responsible for financing, constructing, owning, operating and maintaining the solar plants for a period of 25 years. NML will purchase the entire electricity generated by the projects for captive consumption, with the tariff to be discovered through a competitive bidding process.
The first project involves a 25 MWp DC/20 MW AC solar PV plant at Overburden Dump-C of the Pakribarwadih Coal Mining Project in Hazaribagh, Jharkhand. Approximately 80 acres of dump-top land has been identified for the development, with the project expected to be executed within 18 months. NML has indicated that the proposed capacity could potentially be increased to 30–35 MWp during the subsequent Request for Proposal (RFP) stage.
The second project, also planned at 25 MWp DC/20 MW AC, will be developed at the MGR Bulb Area of the Talaipalli Coal Mining Project in Sundargarh, Chhattisgarh. The project will utilise around 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 Utilisation Factor (CUF) of 22%. The EOI has been issued under reference NML/Engg/EOI/01, with August 11, 2026, specified as the publication date. Interested participants can submit clarification queries until August 18, 2026, while the deadline for submission of the EOI is September 1, 2026.
No Earnest Money Deposit (EMD) or Performance Bank Guarantee (PBG) is required at the EOI stage. These requirements, along with other commercial terms and conditions, are expected to be finalised during the subsequent RFP and Power Purchase Agreement (PPA) process.
The EOI is non-binding and has been issued to assess market interest, technical capabilities, commercial viability and industry feedback before NML proceeds with the formal tendering process. Eligible participants include Indian companies, firms, Central Public Sector Undertakings, State Governments, PSUs and consortiums of up to three entities.
NML has also reserved the right to limit participation in the subsequent RFP to entities that submit responses to the current EOI. Applications are required to be submitted digitally through NTPC’s e-procurement portal.
