Tata Power has announced a major milestone in strengthening India’s northern power grid with the successful commissioning of the 400 kV Koteshwar–Rishikesh transmission line. This new infrastructure link, developed under NRSS XXXVI Transmission Limited (NRSS) — a project acquired by Resurgent Power Ventures Pte Ltd, the joint venture backed by Tata Power, ICICI Bank and global investors — is designed to carry 1,000 MW of hydropower from the Tehri–Koteshwar generation complex in Uttarakhand to key northern states.
With the new line now live, clean hydropower can flow more efficiently to Uttarakhand, Haryana, Punjab, Uttar Pradesh, Jammu & Kashmir, Himachal Pradesh, Chandigarh, Rajasthan, and Delhi. This is expected to significantly bolster regional energy security, improve grid reliability and support India’s growing demand for renewable power.
What makes the project particularly noteworthy is the extreme terrain in which it was built. The transmission line cuts through the challenging Himalayan regions of New Tehri and Dehradun, climbing to altitudes of more than 1,816 metres. Engineers and workers had to navigate remote mountain stretches, transport materials through head-loading, and comply with stringent environmental rules while operating in forested zones. Despite these hurdles, over 500 skilled workers completed the physical construction between November 2024 and December 2025 after receiving clearance for 103 hectares of land.
The achievement underscores Tata Power’s strong execution capabilities in complex, high-precision and environmentally sensitive zones. The company also highlighted its focus on safety and sustainable infrastructure development throughout the project lifecycle.
The Koteshwar–Rishikesh line marks the third commissioning under the NRSS initiative. Earlier components included the 400 kV LILO Sikar–Neemrana Double Circuit line spanning 3.1 circuit kilometres and the 400 kV LILO Babai–Bhiwani Double Circuit line covering 222 circuit kilometres.
With this addition, Tata Power now has a total of 7,083 circuit kilometres of transmission lines either operational or under execution across the country, reinforcing its role as a key player in strengthening India’s power transmission backbone and supporting the shift toward clean energy.
