Power Grid Corporation of India Ltd (PGCIL) has been named as the successful bidder for an interstate transmission system (ISTS) scheme in Rajasthan, awarded under the tariff-based competitive bidding (TBCB) mechanism.
In a brief stock exchange filing, PGCIL said that it has been declared as successful bidder for an ISTS project officially termed as ““Transmission system for evacuation of power from REZ in Rajasthan (20 GW) under Phase-III Part H” on build, own, operate and transfer (BOOT) basis.
Bid process coordinator PFC Consulting Ltd (PFCCL), it is learnt, handed over the letter of intent to PGCIL on September 4, 2023.
The PGCIL release noted that the project entails establishment of a new 765/400kV substation at Dausa, one 765kV double-circuit transmission line, LILO of both circuits of one 765kV D/C Line and LILO of both circuits of one 400kV double-circuit line at new 765/400kV substation in Rajasthan, and associated bay extension works.
Four contenders
It is learnt from other reliable sources that three other contenders – Tata Power, Sterlite Power and India Grid Trust (IndiGrid) – were qualified to submit their final bids. It is however, not known, which bidders ultimately submitted their bids and which of these three proceeded to the e-reverse auction (e-RA) stage.
