Tata Power Company Ltd on Friday (January 20) said it has commissioned two critical 765 kV extra high voltage (EHV) transmission corridors in Uttar Pradesh, strengthening the northern region’s power transmission network and improving grid reliability across the state.
The newly-commissioned corridors include the 380-circuit kilometre Mainpuri–Bara line and the 194-circuit kilometre Mainpuri–Unnao line, developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project. Together, the lines form a backbone for reliable power flow within Uttar Pradesh and across the northern grid.
The project, acquired by Resurgent Power Ventures Pte Limited — a joint venture led by Tata Power, ICICI Bank, and global investors — was part of the resolution of previously stressed power assets. Once operational, the corridors will facilitate the evacuation of over 3,000 MW of thermal power generated within the state, supporting grid stability and long-term energy security in Uttar Pradesh.

The execution of the project involved complex engineering and large-scale resource deployment, including over 42,000 tonnes of tower steel, 6,900 km of conductor stringing, and completion of more than 100 major crossings such as railways, rivers, and existing transmission lines. The corridors also pass through forest stretches and were constructed in compliance with environmental and regulatory requirements.
With the commissioning of these two 765 kV corridors, Tata Power now has 5,312 circuit kilometres of transmission lines operational, with an additional 1,997 circuit km under construction. The expanding portfolio underscores the company’s growing role in building and modernising India’s high-voltage transmission backbone at a time when grid capacity is critical to sustaining economic growth.
Shares of Tata Power Company Ltd ended at ₹366.60, up by ₹0.20, or 0.055%, on the BSE today, January 30.
