The Tata Power Company Limited has commissioned two critical 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, enhancing grid reliability and reinforcing the northern region’s power transmission capacity.
Developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project, the newly commissioned Mainpuri–Bara corridor spans 380 circuit kilometres, while the Mainpuri–Unnao corridor extends across 194 circuit kilometres. Together, these lines play a central role in ensuring reliable power flow across Uttar Pradesh and the interconnected northern grid, while adding to Tata Power’s growing national transmission portfolio.
The project was acquired by Resurgent Power Ventures Pte. Ltd.—a joint venture led by Tata Power, ICICI Bank and global investors—as part of efforts to resolve stressed power assets. With commissioning complete, the corridors will enable the evacuation of more than 3,000 MW of thermal power generated within the state, contributing to improved grid stability and long-term energy security.
Execution of the project involved complex engineering challenges and extensive resource deployment. The construction required over 42,000 metric tonnes of tower steel, nearly 6,900 kilometres of conductor stringing, and the successful completion of over 100 major crossings, including railway tracks, rivers and existing transmission networks. Sections of the project pass through forest areas and were executed in strict compliance with environmental and regulatory requirements.
Despite these complexities, the project was completed in line with Tata Power’s high standards for safety, quality and operational excellence, reinforcing its position as a leading transmission infrastructure developer.
With the commissioning of these corridors, Tata Power’s operational transmission network now totals 5,312 circuit kilometres, with another 1,997 circuit kilometres under development, supporting India’s growing power demand and economic growth.
