In a major boost to India’s northern power network, Tata Power has announced the commissioning of the 400 kV Koteshwar–Rishikesh transmission line. This crucial link will help evacuate 1,000 MW of hydropower from the Tehri–Koteshwar generation complex in Uttarakhand and deliver it to several northern states and Union Territories.
The project was implemented through NRSS XXXVI Transmission Limited (NRSS), which was acquired by Resurgent Power Ventures Pte Limited. Resurgent Power is a joint venture promoted by Tata Power, ICICI Bank Limited and global investors.
With this new line in place, clean and renewable power will flow not just to Uttarakhand but also to Haryana, Punjab, Uttar Pradesh, Jammu & Kashmir, Himachal Pradesh, Chandigarh, Rajasthan and Delhi. The development is expected to significantly improve energy security and strengthen grid reliability across the region.
Built through some of the most difficult Himalayan terrain in the New Tehri and Dehradun districts, the transmission line reaches heights of over 1,816 metres above sea level. The project required exceptional engineering effort, including transporting materials through head-loading in remote mountain areas and strictly complying with environmental regulations in forest zones.
Despite tough geographical and logistical challenges, more than 500 skilled workers completed the physical execution of the project within just one year, from November 2024 to December 2025, after securing land clearances for 103 hectares. The timely commissioning highlights the company’s strong focus on safety, precision execution and sustainable infrastructure development.
The Koteshwar–Rishikesh line marks the third major commissioning milestone under the NRSS project. Earlier milestones include 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’s transmission portfolio now stands at 7,083 circuit kilometres of lines that are operational or under execution across India, further strengthening its role in building the country’s electricity transmission backbone.
