Cabinet approves over $2.49 billion for inter-state transmission line backing 13 GW of renewable energy project in Ladakh


The Cabinet Committee on Economic Affairs, chaired by Prime Minister, Narendra Modi, has approved the inter-state transmission system (ISTS) for a 13 GW renewable energy project under the Green Energy Corridor (GEC) Phase-II Scheme.

The transmission line for evacuating this power will pass through Himachal Pradesh and Punjab up to Kaithal in Haryana, where it will be integrated with the national grid.

An interconnection is also planned from this project in Leh to the existing Ladakh grid to ensure a reliable power supply to Ladakh. It will also be connected to the Leh-Alusteng-Srinagar line to provide power to Jammu & Kashmir.

The project is targeted to be set up by FY 2029-30 with a total estimated cost of INR 20,773.70 crore (over $2.49 billion) and central financial assistance (CFA) at 40% of the project cost, i.e., INR 8,309.48 crore.

The project will entail setting up 713 km transmission lines (including 480 km HVDC line) and 5 GW capacity of HVDC terminal each at Pang (Ladakh) and Kaithal (Haryana).

“Keeping in view the complex terrain, adverse climatic conditions and defense sensitivities of the Ladakh region, Power Grid Corp. of India Ltd will be the implementing agency for this project. State-of-the-art voltage source converter (VSC) based high-voltage direct current (HVDC) system and extra-high-voltage alternating current (EHVAC) systems will be deployed,” read a government release.

This project is in addition to Intra-State Transmission System Green Energy Corridor Phase-II (InSTS GEC-II), which is already under implementation in the States of Gujarat, Himachal Pradesh, Karnataka, Kerala, Rajasthan, Tamil Nadu, and Uttar Pradesh for grid integration and power evacuation of approx. 20 GW of RE power and is expected to be completed by 2026.
