The Tata Power Company Limited (Tata Power) has commissioned two major 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, strengthening the state’s transmission backbone and improving grid reliability across the northern region. The newly commissioned transmission corridors include the Mainpuri–Bara line, which spans 380 circuit kilometres, and the Mainpuri–Unnao line, covering 194 circuit kilometres. Together, these two high-capacity lines total 574 circuit kilometres (CKM) and have been developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project.
The corridors play a crucial role in strengthening the state’s power infrastructure by enabling smooth and reliable electricity flow across Uttar Pradesh and supporting stability across the wider northern grid. The project was acquired by Resurgent Power Ventures Pte Limited, a joint venture led by Tata Power, in partnership with ICICI Bank and global investors, as part of the resolution process for previously stressed power assets. Once fully operational, the corridors will enable evacuation of more than 3,000 MW of thermal power generated within the state.
Construction of the transmission lines involved complex engineering and large-scale resource deployment, including the use of over 42,000 metric tonnes of tower steel, nearly 6,900 kilometres of conductor stringing, and completion of more than 100 major crossings across railway lines, rivers and existing transmission routes. The lines also pass through forest stretches and were built in compliance with environmental and regulatory conditions. Despite these challenges, the project was completed in line with Tata Power’s standards for quality and safety.
With this commissioning, Tata Power’s operational transmission network now stands at 5,312 circuit kilometres, with another 1,997 circuit kilometres currently under construction. The growing portfolio reflects Tata Power’s expanding role in developing India’s high-voltage transmission infrastructure at a time when grid reinforcement is becoming increasingly critical.
Tata Power, part of the Tata Group, is one of India’s largest integrated power companies with a diversified portfolio of 16.3 GW spanning generation (renewable and conventional), transmission, distribution, trading, storage solutions, and solar cell and module manufacturing. The company’s clean energy generation capacity stands at 7.5 GW, accounting for 46% of its total capacity. Tata Power has set a target to achieve Net Zero by 2045 and currently serves around 13 million customers nationwide.
