Tata Power has successfully commissioned two strategic 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, marking a significant milestone in strengthening the northern region’s electricity transmission network and improving grid resilience across the state.
The corridors—Mainpuri–Bara (380 circuit kilometres) and Mainpuri–Unnao (194 circuit kilometres)—have been developed as part of the South East UP Power Transmission Company Limited (SEUPPTCL) project. These lines now form a vital link for dependable power transmission within Uttar Pradesh and the wider northern grid, while expanding Tata Power’s national transmission footprint.
The project, acquired by Resurgent Power Ventures Pte. Ltd., a joint venture led by Tata Power with ICICI Bank and global investors, represents a key step in resolving stressed power transmission assets. Once fully operational, the two corridors will facilitate the evacuation of over 3,000 MW of thermal power produced within the state, improving grid stability and supporting long-term energy security objectives.
Project execution required large-scale engineering expertise and logistical coordination. Construction involved the use of more than 42,000 metric tonnes of tower steel, around 6,900 kilometres of conductor stringing, and over 100 major crossings across railway lines, rivers and existing transmission corridors. The routes also traverse forest stretches and were completed in full compliance with environmental and regulatory standards.
Despite these challenges, Tata Power delivered the project in accordance with its strict benchmarks for quality, safety and operational performance, further strengthening its credentials in the transmission infrastructure space.
Following the commissioning, Tata Power’s operational transmission network has expanded to 5,312 circuit kilometres, with an additional 1,997 circuit kilometres under construction, underscoring the company’s role in modernising India’s power transmission ecosystem.
