NTPC Renewable Energy Limited (NTPC REL), a wholly owned subsidiary of NTPC Green Energy Limited, has invited online bids for the Balance of System (BOS) package for developing 1000 MW (2×300 MW + 2×200 MW) grid-connected solar PV projects at Bikaner, Rajasthan. The tender was issued on April 9, 2025. The tender process will be conducted through the Electronic Tendering System (ETS) portal using a single-stage, two-envelope bidding format, followed by a reverse auction.
The scope of the work involves the design, engineering, supply, installation, testing, and commissioning of the solar PV plant excluding the supply of solar modules. It includes site grading, construction of module mounting structures, inverter rooms, HT switchgear, laying HT cables, SCADA systems, CCTV monitoring, dynamic reactive power compensation, and a weather monitoring station. The successful bidder will also be responsible for the operations and maintenance of the project for three years.
The bidding documents will be available for download from April 11 to April 21, 2025, till 5:00 PM IST. A pre-bid conference is scheduled for April 24, 2025, at 11:00 AM. The last date for submission of techno-commercial and price bids is May 15, 2025, by 3:00 PM, and the techno-commercial bids will be opened on the same day at 3:30 PM. The date for price bid opening and reverse auction will be announced later.
The cost of the bidding documents is ₹22,500. Bidders are required to submit a non-disclosure agreement (NDA) to access the bidding documents. The bid security amount depends on the number of blocks quoted. For one block, the bid security is ₹5 crore, for two blocks it’s ₹10 crore, for three blocks it’s ₹20 crore, and for all four blocks, it is also ₹20 crore. The bidding document specifies that any bid not accompanied by the appropriate bid security will be rejected as non-responsive.
The project is divided into four blocks: Block-VI and Block-VII (each 300 MW), and Block-VIII and Block-IX (each 200 MW). Bidders can quote for one or more blocks but must provide bid security in proportion to the total capacity quoted.
The financial eligibility criteria include an average annual turnover of at least ₹250 crore for quoting 1000 MW, with scaled-down requirements for lower capacities. The bidder’s net worth must not be less than 100% of their paid-up share capital. In case the bidder does not meet this on its own, the net worth of its holding or subsidiary companies can be considered.
The technical eligibility criteria require the bidder to have experience in the design, supply, and commissioning of at least 40 MWp of grid-connected solar PV plants, including one plant of at least 10 MWp capacity that has been operational for six months or more. Alternatively, the bidder should be a developer of similar capacity projects or should have executed comparable industrial or substation works.
