The Tata Power Company Limited, one of India’s largest integrated power companies, has successfully commissioned two significant 765 kV Extra High Voltage transmission corridors in Uttar Pradesh. This achievement represents an important step in strengthening the power transmission network in the northern region and enhancing the overall reliability of the state’s electricity grid.
The newly commissioned corridors, Mainpuri–Bara, spanning 380 circuit kilometres, and Mainpuri–Unnao, covering 194 circuit kilometres, were developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project. These corridors are part of Tata Power’s growing national transmission portfolio and together form a critical backbone for the efficient and reliable flow of electricity within Uttar Pradesh and across the northern grid.
The project was acquired by Resurgent Power Ventures Pte. Ltd., a joint venture led by Tata Power along with ICICI Bank and global investors, as part of the resolution of previously stressed power assets. Once fully operational, the two corridors will enable the evacuation of more than 3,000 MW of thermal power generated within the state. This will significantly improve grid stability and contribute to Uttar Pradesh’s long-term energy security.
The execution of the project involved complex engineering and extensive resource deployment. Construction required over 42,000 metric tonnes of tower steel, 6,900 kilometres of conductor stringing, and the completion of more than 100 major crossings, including railway lines, rivers, and existing transmission corridors.
The transmission lines also pass through forest areas and were constructed in strict compliance with environmental and regulatory requirements.Despite these challenges, the project was completed in accordance with Tata Power’s standards for operational excellence, quality execution, and stringent safety protocols, reinforcing the company’s position as a leading developer of transmission infrastructure.
With the commissioning of these two corridors, Tata Power now operates 5,312 circuit kilometres of transmission lines, with an additional 1,997 circuit kilometres under construction. This expanding portfolio reflects the company’s growing role in developing and modernising India’s high-voltage transmission network, which is essential for supporting the country’s economic growth and ensuring a stable power supply.
