The Tata Power Company Limited (Tata Power), one of India’s largest integrated power companies, has commissioned two key 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, significantly reinforcing the state’s power transmission infrastructure and enhancing grid reliability across the northern region.
The newly operational corridors—Mainpuri–Bara, spanning 380 circuit kilometres, and Mainpuri–Unnao, covering 194 circuit kilometres—have been developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project. These assets are part of Tata Power’s expanding national transmission portfolio and together form a critical backbone for reliable power flow 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 process for stressed power assets. With commissioning complete, the two corridors will enable the evacuation of more than 3,000 MW of thermal power generated within the state, strengthening grid stability and supporting Uttar Pradesh’s long-term energy security goals.
Execution of the project involved complex engineering and extensive resource mobilisation. The construction required over 42,000 metric tonnes of tower steel, approximately 6,900 kilometres of conductor stringing, and the completion of more than 100 major crossings, including railways, rivers and existing transmission lines. Portions of the corridors also pass through forest areas and were constructed in strict adherence to environmental and regulatory norms.
Despite the scale and complexity, the project was delivered in line with Tata Power’s benchmarks for quality, safety and operational excellence, reinforcing its standing as a leading transmission infrastructure developer.
With these additions, Tata Power’s operational transmission network now stands at 5,312 circuit kilometres, with another 1,997 circuit kilometres currently under construction, highlighting its growing role in strengthening India’s high-voltage transmission backbone.
