Tata Power has commissioned two major 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, strengthening the state’s electricity transmission network and enhancing reliability across the northern power grid.
The Mainpuri–Bara corridor, spanning 380 circuit kilometres, and the Mainpuri–Unnao corridor, covering 194 circuit kilometres, were developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project. These corridors form a critical backbone for power transmission within Uttar Pradesh and contribute to Tata Power’s expanding national transmission portfolio.
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 operational, the two corridors will facilitate the evacuation of more than 3,000 MW of thermal power generated within the state, significantly improving grid stability and supporting long-term energy security goals.
Construction of the project involved complex engineering and large-scale deployment of resources. Over 42,000 metric tonnes of tower steel were used, along with approximately 6,900 kilometres of conductor stringing. The execution also included more than 100 major crossings involving railway lines, rivers and existing transmission corridors. The routes traverse forest areas and were built in compliance with all environmental and regulatory norms.
Despite these challenges, Tata Power delivered the project in line with its stringent benchmarks for quality, safety and operational excellence, reinforcing its reputation as a leading transmission infrastructure developer.
With these additions, Tata Power now operates 5,312 circuit kilometres of transmission lines, with another 1,997 circuit kilometres under construction, highlighting its role in strengthening India’s high-voltage power transmission network.
