The National Thermal Power Corporation (NTPC) has extended the bid submission deadline for the balance of system package (BoS) for its 735 (3×245) MW Nokh solar project in the state of Rajasthan.

The last submission date for the receipt of bids for Stage-I techno-commercial bids was revised to May 19, 2020, from April 27, 2020. The project was initially floated on March 26, 2020.

The scope of work includes the design, engineering, manufacturing, supply, packing, transportation unloading storage, installation, testing, and commissioning of solar projects, excluding the supply of solar PV modules.

Interest bidders are expected to deposit a bid security amount of ₹50 million (~$659,204). The successful bidder will also be responsible for the design and construction of module mounting structure (MMS) for solar PV panels, including the fixing of modules with module mounting structures and PV module interconnection.

To be eligible to take part in the competitive bidding process, applicants must have had a minimum average annual turnover of ₹670 million (~$8.83 million) for the first block of 245 MW, and ₹1.34 billion (~$17.66 million) for the second block.

Bidders must also have experience supplying at least 40 MW of BoS projects, of which at least one project was 10 MW or higher. The project is also expected to have been operating successfully for at least six months.

Additionally, the bidder should have executed at least one electrical sub-station of at least 33 kV voltage level, consisting of equipment such as circuit breakers and power transformers.

Earlier, the NTPC tendered a 90 MW balance of system package for the Anta Solar Power Project in Rajasthan. The scope of work included the design, engineering, manufacturing, supply, packing, forwarding, transportation, unloading storage, installation, testing, and commissioning of the solar project, excluding the supply of solar PV modules.

More recently, Mercom reported that the NTPC invited bids for an inverter transformer package for the Solapur solar PV project in Maharashtra. The scope of work includes the design, engineering, manufacturing, supply, packaging, testing, installation, and commissioning of inverter-transformer of minimum cumulative capacity of 23 MVA having an HV side voltage of 11 kV at Solapur.
