The Tata Power Company Limited (Tata Power), one of India’s largest integrated power utilities, has successfully commissioned two critical 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, marking a significant milestone in strengthening the northern region’s power transmission network and enhancing grid reliability across the state.
The newly operational transmission lines include the Mainpuri–Bara corridor spanning 380 circuit kilometres and the Mainpuri–Unnao corridor covering 194 circuit kilometres. Developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project, these corridors form a vital part of Tata Power’s expanding national transmission portfolio and serve as a robust backbone for reliable power flow within Uttar Pradesh and the broader northern grid.
The project was acquired by Resurgent Power Ventures Pte. Limited, a joint venture led by Tata Power along with ICICI Bank and global investors, as part of the resolution process for previously stressed power assets. With commissioning now complete, the two 765 kV corridors are expected to facilitate the evacuation of more than 3,000 MW of thermal power generated within Uttar Pradesh, significantly improving grid stability and supporting the state’s long-term energy security and growing electricity demand.
Execution of the project involved complex engineering challenges and large-scale resource deployment. Construction required over 42,000 metric tonnes of tower steel and approximately 6,900 kilometres of conductor stringing. The transmission lines also involved more than 100 major crossings, including railway tracks, rivers and existing transmission corridors, while passing through forest stretches under strict environmental and regulatory compliance. Despite these challenges, the project was delivered in line with Tata Power’s benchmarks for operational excellence, quality execution and stringent safety standards.
With the commissioning of these two high-capacity corridors, Tata Power’s operational transmission network now stands at 5,312 circuit kilometres, with an additional 1,997 circuit kilometres currently under construction. This expanding portfolio highlights the company’s growing role in building and modernising India’s high-voltage transmission infrastructure at a time when grid capacity and reliability are critical to sustaining economic growth, industrial expansion and energy transition goals.
