The Committee of Directors on Investment on Projects of Power Grid Corporation of India Ltd (PGCIL) has approved three projects with an aggregate cost of Rs.584.13 crore.
In a meeting held on May 15, 2026, the said committee approved three projects that PGCIL would be implementing under the regulated tariff mechanism (RTM) route.
All these projects were earlier approved by the National Committee on Transmission (NCT) and were subsequently allotted to PGCIL by Central Transmission Utility of India Ltd (CTUIL).
The first project entails augmentation of PGCIL’s Tuticorin-II GIS substation in Tamil by the addition of 1×500 MVA, 400/230kV interconnecting transformer, the seventh such at the substation. Estimated to cost Rs.132.06 crore, this project is scheduled to commission by February 17, 2028.
The other two projects involve installation of OPGW (optical ground wire) and associated communication systems on existing ISTS lines. One project, costing Rs.308.49 crore, relates to the Western Region grid and the other, with an outlay of Rs.143.58 crore, pertains to the Eastern Region grid. Both the projects have an implementation timeframe of 30 months, and are scheduled to commission by September 18, 2028.
According to information available, NCT has approved a similar OPGW project to be implemented by PGCIL in the Northeastern Region (NER) grid. This project, with a relatively smaller cost of around Rs.18 crore, will be executed by PGCIL under the RTM mechanism.
