STATEMENT REFERRED TO IN REPLY TO PARTS (a) & (b) IN RESPECT OF LOK SABHA STARRED QUESTION NO.196 FOR REPLY ON 12.02.2026 REGARDING POWER  TRANSMISSION  OR  GRID-STRENGTHENING  PROJECTS  FOR  TAMIL NADU ASKED BY SHRI SASIKANTH SENTHIL

*********

- (a) & (b) : As  reported  by  TNEB  Ltd.,  the  delay  in  completion  of  the  power transmission projects approved by the Central Government for integration of Renewable Energy (RE) generation in the State of Tamil Nadu do not have any impact on the reliable electricity supply to industries and households.

Presently, five Inter State Transmission System (ISTS) projects are under implementation  in  Tamil  Nadu  for  integration  of  Renewable  Energy  (RE) generation and grid-strengthening. The details of status of the ISTS projects along with the timelines are given in Annexure-I. The delay in the two projects is  primarily  due  to  supply  constraint  of  Transformers  and  Gas  Insulated Substation (GIS) equipment.

Also, nine Intra State Transmission System (In-STS) projects have been approved by Ministry of New and Renewable Energy (MNRE) under Green Energy Corridor (GEC)-II Scheme in Tamil Nadu, which are being implemented by Tamil Nadu  Transmission  Corporation  Limited  (TANTRANSCO).  The  details  of  the status of projects under GEC-II along with timelines are given in Annexure-II. The delay in the two under implementation GEC-II projects is primarily due to Right-of-Way (RoW) issues faced by TANTRANSCO.

The following measures are taken by the Central Government to ease and mitigate the challenges and issues faced by Transmission Project developers:

- I Monitoring mechanisms for ISTS projects:
- I. Monitoring  of  Projects:  Transmission  projects  are  monitored  and reviewed by the Central Agencies including Central Electricity Authority (CEA) and Central Transmission Utility of India Ltd. (CTUIL) periodically and also reviewed in the Ministry of Power.
- II. Stakeholder Consultations: Regular meetings are conducted with State governments, District Authorities and concerned Transmission Project developers to resolve bottlenecks collaboratively.
- III. Monitoring mechanisms for projects under GEC-II scheme and In-STS: The projects are monitored by the CEA and State Transmission Utilities (STU)  with  regular  review  meetings  held  internally  and  with  project developers to expedite the works. MNRE is monitoring the implementation  of  the  GEC-II  scheme  through  the  Project  Appraisal Committee (PAC). Also high level review meetings are held at State Government to monitor the progress of the projects.
