The Tata Power Company Limited (Tata Power) has successfully commissioned two critical 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, marking a major step in strengthening the northern region’s power transmission network and improving grid reliability across the state.
The newly commissioned 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 and form part of Tata Power’s expanding national transmission portfolio. Together, the lines form a critical backbone for reliable power flow within Uttar Pradesh and across the northern grid.
The project, acquired by Resurgent Power Ventures Pte. Ltd., a joint venture led by Tata Power, ICICI Bank and global investors, is part of the resolution of previously stressed power assets. Once operational, the two corridors will facilitate the evacuation of over 3,000 MW of thermal power generated within the state, significantly improving grid stability and supporting Uttar Pradesh’s long-term energy security objectives.
The execution of the project involved complex engineering and large-scale deployment of resources. 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.
