PGCIL receives letter of intent for Tumkur-II REZ interstate transmission scheme
- April 2, 2026
Power Grid Corporation of India Ltd (PGCIL) has received the letter of intent for developing an interstate transmission system (ISTS) scheme in Karnataka, under the tariff-based competitive bidding (TBCB) mode.
In a brief stock exchange filing, PGCIL said that it emerged as the successful bidder under TBCB and received the letter of intent dated March 30, 2026, on April 1, 2026.
The project is officially termed as “Transmission system strengthening at Tumkur-II for integration of additional RE potential (2.7 GW)” and is housed under project SPV “Tumkur II RE Transmission Ltd” that is currently a wholly-owned subsidiary of bid process coordinator PFC Consulting Ltd (PFCCL).
As reported by tndindia.com on March 29, 2026, PGCIL was in the fray for this project alongside four other bidders – Adani Energy Solutions Ltd, Resonia Ltd, Dilip Buildcon Ltd and G R Infraprojects Ltd.
The project
The Tumkur II RE project essentially involves augmentation of the upcoming Tumkur-II Pooling Station (PS) in Karnataka by the addition of six 400/220kV, 1×500 MVA interconnecting transformers to the upcoming Tumkur-II Pooling Station (PS) in Karnataka. This scheme will also connect Tumkur-II PS to Madhugiri substation through a 400kV double-circuit (quad) line running around 100 km. With an estimated outlay of Rs.1,051 crore, the project has an implementation timeframe of 24 months.
It may be mentioned that Tumkur-II PS (4×500 MVA, 400/220kV) is coming up through “Tumkur-II REZ Power Transmission Ltd,” a TBCB subsidiary of G R Infraprojects.
More schemes up for award
In the coming weeks, it is likely that letters of intent will be issued to two more ISTS-TBCB schemes housed under “Kurnool IV REZ Power Transmission Ltd” and “NERGS III Siang Basin Transmission Ltd.” Shortlisting of bidders has already taken place, and the e-reverse auction for at least one of the two schemes has been recently conducted, according to informed sources.
