NTPC Renewable Energy Limited, a wholly owned subsidiary of NTPC Green Energy Limited, has invited online bids for the Balance of System (BoS) package for a 900 MW (3×300 MW) grid-connected solar PV project at Fatehgarh, Rajasthan. The bidding will follow a single-stage, two-envelope process, which includes a techno-commercial bid and a price bid, followed by a reverse auction.
The scope of work includes designing, engineering, manufacturing, supplying, transporting, and installing various components of the solar photovoltaic plant, excluding the supply of solar PV modules. The contractor will be responsible for site preparation, topographical surveys, geotechnical investigations, and constructing foundations for tracker-based module mounting structures. Other tasks include arranging power and water supply, constructing pre-engineered inverter rooms or switchgear rooms, and setting up all electrical and civil works necessary for grid integration. The power evacuation for the project will be up to the 33kV main pooling switchgear at the owner’s substation.
Additional work involves laying and terminating HT cables, installing a module cleaning system, building internal roads and drainage systems, setting up a SCADA system for remote monitoring, and ensuring compliance with grid regulations through reactive power compensation and harmonic filters. Security measures, including CCTV surveillance, will be implemented. The selected contractor will also be responsible for the operation and maintenance of the plant, including electrical equipment, consumables, and spare parts, for three years from the commissioning date.
NTPC Renewable Energy Limited plans to finance the project through its own resources or borrowings. The bidding documents are available for download from April 5, 2025, to April 15, 2025, until 5:00 PM. A pre-bid conference will be held on April 18, 2025, at 11:00 AM. The last date for submitting both techno-commercial and price bids is May 7, 2025, by 3:00 PM, with the techno-commercial bid opening scheduled for 3:30 PM on the same day. The date for the price bid opening and reverse auction will be announced later. The cost of the bidding documents is ₹22,500.
The eligibility criteria require bidders to have designed, supplied, and commissioned a solar PV-based grid-connected power plant with a cumulative installed capacity of 40 MWp or higher, including at least one plant of 10 MWp or more that has been in successful operation for at least six months before the bid opening date. Alternatively, bidders should be developers of solar PV power plants meeting the same capacity requirements. Another eligibility option allows bidders to have executed industrial projects in power, steel, oil and gas, petrochemical, fertilizer, cement, coal mining, or process industries with minimum financial criteria in the past ten years.
Financially, bidders must meet an average annual turnover criterion based on the bid capacity. For a 300 MW block, the required turnover is ₹86 crore, for 600 MW it is ₹172 crore, and for 900 MW it is ₹258 crore. If a bidder does not meet this requirement, its holding company can provide financial support, subject to net worth conditions.
