New Delhi: Tata Power on Tuesday announced the commissioning of the 400 kV Koteshwar–Rishikesh transmission line, a key project that will enable the evacuation of 1,000 MW of hydropower from the Tehri–Koteshwar generation complex in Uttarakhand to multiple northern states and Union Territories.

The company said the line was executed under NRSS XXXVI Transmission Limited (NRSS), acquired by Resurgent Power Ventures Pte Ltd, a joint venture promoted by Tata Power, ICICI Bank and global investors.
According to the statement, the new line will channel clean, renewable energy to Uttarakhand, Haryana, Punjab, Uttar Pradesh, Jammu & Kashmir, Himachal Pradesh, Chandigarh, Rajasthan and Delhi, significantly strengthening regional energy security and grid reliability.
Tata Power said the line was constructed across “some of the most challenging Himalayan terrain” in New Tehri and Dehradun districts, climbing to altitudes exceeding 1,816 metres above sea level. The project required “extraordinary engineering ingenuity,” including transporting materials through head-loading in remote mountainous regions and adhering to strict environmental norms in forested zones.
Despite logistical and geographical challenges, more than 500 skilled personnel completed the physical work within a year — from November 2024 to December 2025 — following land clearance for 103 hectares. The company said the on-time commissioning demonstrates its strengths in “safety, high-precision execution and sustainable infrastructure development”.
This line represents the third major commissioning milestone under the NRSS project, following earlier elements that 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).
