Tata Power has announced the commissioning of the 400 kV Koteshwar–Rishikesh transmission line, a key addition to India’s northern power corridor, enabling evacuation of 1,000 MW of hydropower from the Tehri–Koteshwar complex in Uttarakhand to multiple northern states and Union Territories.
The project was executed under NRSS XXXVI Transmission Ltd., acquired by Resurgent Power Ventures Pvt. Ltd.—a joint venture promoted by Tata Power, ICICI Bank Limited, and global investors.
The new line will channel clean, renewable energy not only to Uttarakhand but also to Haryana, Punjab, Uttar Pradesh, Jammu & Kashmir, Himachal Pradesh, Chandigarh, Rajasthan, and Delhi, significantly strengthening regional energy security and grid reliability.
Constructed across some of the most challenging Himalayan terrain in the New Tehri and Dehradun districts, the transmission line climbs to altitudes exceeding 1,816 meters above sea level. The project demanded extraordinary engineering ingenuity, from transporting materials through head-loading in remote mountainous regions to adhering to strict environmental norms while operating in forested zones.
Despite the logistical and geographical hurdles, more than 500 skilled personnel completed the project’s physical work within a single year (November 2024 to December 2025), following land clearance for 103 hectares. The successful, on-time commissioning of the project demonstrates Tata Power’s strong capabilities in safety, high-precision execution, and sustainable infrastructure development.
This line represents the third major commissioning milestone under the NRSS XXXVI project. Earlier elements include the 400 kV LILO Sikar–Neemrana Double Circuit line (3.1 circuit km) and the 400 kV LILO Babai–Bhiwani Double Circuit line (222 circuit km).
With its addition, Tata Power now has 7,083 circuit km of transmission lines operational/under execution across India, further reinforcing its role in fortifying the nation’s electricity transmission backbone.
