POWERGRID has successfully acquired the Special Purpose Vehicle (SPV) ‘Kudankulam ISTS Transmission Limited’ for the Transmission System under ISTS (Inter-State Transmission System) to evacuate power from Kudankulam Units 3 and 4 (2×1000 MW). The project, estimated at ₹548 crore (as per NCT estimations), represents a significant step in strengthening the southern region’s power transmission infrastructure.
Project Scope and Infrastructure Development
The project involves:
- Establishing the KNPP 3&4 – Tuticorin-II GIS PS 400 kV (quad) D/C line.
- Installing two 400kV GIS line terminal equipment at Tuticorin-II GIS.
Facilitating Regional Power Transfer
This strategic transmission system will enable efficient evacuation of power from Kudankulam Units 3 and 4, part of the Nuclear Power Corporation of India Limited (NPCIL) generation project. It will bolster power transfer capabilities across the southern region, ensuring reliable energy delivery and supporting regional development.
This acquisition underscores POWERGRID’s commitment to advancing India’s energy infrastructure and meeting the growing power demands of the nation.
