NTPC Mining Limited (NML), a wholly owned subsidiary of NTPC Limited, has invited Expressions of Interest (EOI) from eligible companies for developing 50 MWp of ground-mounted solar PV capacity at two coal mining locations in Jharkhand and Chhattisgarh.
The initiative is part of NML’s efforts to increase renewable energy use and reduce the carbon emissions associated with its mining operations. The projects will be developed under the Renewable Energy Service Company (RESCO) model, under which the selected developer will finance, build, own, operate and maintain the solar plants for 25 years. NML will purchase the electricity generated for captive use at a tariff discovered through competitive bidding.
Two 25 MWp Solar Projects
The first project, with a planned capacity of 25 MWp DC / 20 MW AC, will be located at Overburden Dump-C of the Pakribarwadih Coal Mining Project in Hazaribagh, Jharkhand. Approximately 80 acres of land have been identified for the project, which is expected to be completed within 18 months. NML may increase the capacity to around 30–35 MWp during the subsequent RFP stage.
The second 25 MWp DC / 20 MW AC project is planned at the MGR Bulb Area of the Talaipalli Coal Mining Project in Sundargarh, Chhattisgarh. Around 80 acres of the available 112-acre site will be utilized, with project completion targeted 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 was issued on August 11, 2026, under reference number NML/Engg/EOI/01. Participants can submit clarification queries until August 18, while the deadline for submitting EOI responses is September 1, 2026.
No Earnest Money Deposit (EMD) or Performance Bank Guarantee (PBG) is required at the EOI stage. Commercial and financial requirements are expected to be finalized when NML moves to the formal RFP and Power Purchase Agreement stage.
The EOI is intended to assess industry interest, technical capabilities and commercial feasibility before the formal tender process begins. Eligible participants include Indian companies, firms, Central and State PSUs, government entities and consortiums of up to three members.
NML may also limit participation in the future RFP to entities that respond to the current EOI. Applications must be submitted electronically through the NTPC e-procurement portal.
