Located in Bikaner district, the project is split into three lots: Lot-1 for 1,000 MW (Phase I), Lot-2 for another 1,000 MW (Phase II), and Lot-3 for 450 MW (Phase III).
The scope of work for all three lots includes surveying, designing, engineering, supplying equipment and materials, executing civil works, erecting infrastructure, and conducting testing and commissioning activities. Lot-1 involves constructing a 400/132 kV, 4×315 MVA main park pooling substation (PPS), three 132/33 kV PPS with varied capacities, and associated transmission lines including a 4 km 400 kV double circuit transmission line, a 6 km 132 kV quadruple circuit transmission line with a loop-in loop-out connection, and an 8 km 132 kV double circuit transmission line. Lot-2 includes a similar 400/132 kV main PPS, two 132/33 kV, 6×100 MVA PPS, a 6 km 400 kV double circuit transmission line, and four 7 km 132 kV double circuit transmission lines. Lot-3 comprises two 220/33 kV, 3×80 MVA PPS, a 22 km 220 kV double circuit transmission line with single circuit terminations, and a 5 km single circuit interconnection line. According to the tender guidelines, the bidders are required to submit a bid security amounting to 2 per cent of the estimated procurement cost. The deadline for bid submissions is May 13, 2025.
According to the eligibility criteria, the bidders for Lot-1 and 2 are required to have completed at least one air-insulated (AIS) or hybrid gas-insulated substation (GIS) of 400 kV or more on a turnkey basis in the last seven years. For Lot-3, the requirement is a turnkey AIS/GIS substation of at least 220 kV with a minimum 80 MVA capacity. Transformer suppliers must have delivered at least five transformers rated 220 kV or higher with a capacity of 80 MVA or more over the past seven years, with at least two units operating satisfactorily for one year. Furthermore, the bidders must have a minimum average annual turnover of Rs 4.42 billion for Lot-1, Rs 4.27 billion for Lot-2, and Rs 1.57 billion for Lot-3 over the last three financial years.
