NTPC REL Invites Bids for 1000 MW Solar BOS Package in Rajasthan

NTPC Renewable Energy Ltd. (NTPC REL), a wholly owned subsidiary of NTPC Green Energy Ltd., has invited online bids for the Balance of System (BOS) package for its upcoming 1000 MW solar PV project in Bikaner, Rajasthan.

The tender, issued on April 9, 2025, covers the development of four grid-connected solar blocks, two blocks of 300 MW each and two blocks of 200 MW each. The bidding will be conducted through NTPC’s Electronic Tendering System (ETS) portal in a single-stage, two-envelope format consisting of techno-commercial and price bids, followed by a reverse auction.

The scope of work under the BOS package includes the design, engineering, supply, installation, testing, and commissioning of the solar PV plant, excluding the supply of solar modules. It also involves site grading, the construction of module mounting structures, inverter rooms, HT switchgear installation, HT cable laying, SCADA systems, dynamic reactive power compensation equipment, weather monitoring stations, and CCTV monitoring. In addition to installation, the successful bidder will also be responsible for the project’s operations and maintenance for a period of three years.

Bidding documents will be available for download from April 11 to April 21, 2025, until 5:00 PM IST. A pre-bid conference is scheduled for April 24, 2025. The last date for submission of techno-commercial and price bids is May 15, 2025, with techno-commercial bids to be opened on the same day. The date for price bid opening and the reverse auction will be announced subsequently.

The cost of the bidding documents is INR 22,500. Interested bidders are required to submit a Non-Disclosure Agreement (NDA) to access the tender documents. Bid security must be submitted in proportion to the number of blocks quoted, INR 5 crore for one block, INR 10 crore for two blocks, and INR 20 crore for three or all four blocks. The tender document clearly states that any bid not accompanied by the appropriate bid security will be considered non-responsive and rejected.

The project is divided into four blocks, Block-VI and Block-VII of 300 MW each, and Block-VIII and Block-IX of 200 MW each. Bidders are allowed to quote for one or more blocks, but they must ensure that the corresponding bid security is submitted in line with the total quoted capacity.

To qualify financially, bidders must demonstrate an average annual turnover of at least INR 250 crore for quoting the full 1000 MW capacity. The requirement scales down proportionally for lower quoted capacities. Bidders must also have a net worth equal to or greater than their paid-up share capital. If the bidder does not meet this requirement independently, the net worth of a holding or subsidiary company can be considered.

On the technical front, bidders must have successfully executed at least 40 MWp of grid-connected solar PV projects, including at least one project of 10 MWp or more that has been operational for at least six months. Alternatively, bidders may qualify if they are solar power developers or have completed comparable industrial or substation works of similar scale and complexity.
