NTPC Renewable Energy Invites EPC Bids for 600 MW Solar Projects in Maharashtra's Dhule District

New Delhi: NTPC Renewable Energy Ltd. (NTPC REL), a wholly owned subsidiary of NTPC Green Energy Ltd., has issued an Engineering, Procurement and Construction (EPC) tender for the development of 600 MW of grid-connected solar photovoltaic (PV) capacity at Dhule, Maharashtra. The project forms part of NTPC's ongoing expansion of utility-scale renewable energy infrastructure aimed at supporting India's clean energy and decarbonisation goals.

The tender covers the construction of two 300 MW solar PV projects, with developers allowed to bid for either a single 300 MW block or the entire 600 MW capacity. The procurement will follow a single-stage, two-envelope domestic competitive bidding process, comprising techno-commercial and financial bids, followed by an electronic reverse auction.

According to the tender document, the selected EPC contractor will be responsible for the complete execution of the projects, including detailed engineering, design, manufacturing, supply, transportation, installation, testing and commissioning of the solar power plants. The scope also includes the supply of solar PV modules and all associated balance-of-system components required for successful project implementation.

In addition to the solar generation infrastructure, the contractor will undertake site grading, topographical and geotechnical surveys, construction of tracker-based module mounting structures, inverter stations, internal electrical networks and civil works. The project also includes development of power evacuation facilities up to the 33 kV main pooling switchgear at NTPC REL's pooling substation.

To ensure efficient plant operation and grid compliance, the EPC package includes installation of automated module cleaning systems, SCADA-based monitoring, weather stations, CCTV surveillance, dynamic reactive power compensation equipment, harmonic filters, internal roads and drainage infrastructure.

Following commissioning, the successful bidder will provide comprehensive operation and maintenance (O&M) services for three years, along with the supply of mandatory spare parts to support reliable plant performance.

The bidding schedule specifies that tender documents will be available from June 24 to July 3, 2026, while a pre-bid meeting is scheduled for July 7, 2026. Interested bidders must submit their proposals by July 22, 2026, with the techno-commercial bids scheduled to be opened on the same day.

NTPC REL has prescribed a bid security of INR 20 crore for bidders participating in either a single 300 MW package or the full 600 MW project.

To meet the technical eligibility criteria, bidders must have prior experience in executing or developing grid-connected solar PV projects with a cumulative installed capacity of at least 40 MWp, including at least one project of 10 MWp or larger that has been operational for a minimum of six months. The tender also provides alternative qualification pathways for EPC companies with experience in executing large industrial infrastructure projects and high-voltage substation works.

On the financial side, bidders must demonstrate an average annual turnover ranging between INR 161 crore and INR 338 crore, depending on the capacity being bid for, while also satisfying the minimum net worth requirements specified in the tender.

NTPC REL stated that the project will be funded through a combination of internal resources and borrowings. Prospective bidders are also required to sign a Non-Disclosure Agreement (NDA) before gaining access to the complete bidding documents through the company's electronic procurement portal.

The Dhule solar projects represent another major addition to NTPC Green Energy's expanding renewable energy portfolio. As India's largest power producer continues to scale up investments in utility-scale solar, wind and energy storage projects, such developments are expected to contribute significantly towards the country's target of expanding non-fossil fuel power capacity, strengthening grid reliability and meeting the rapidly growing demand for clean electricity.
