Tata Power Strengthens UP Grid with New 765 kV Transmission Lines

Tata Power Commissions 765 kV Mainpuri–Bara and Mainpuri–Unnao Transmission Lines, Strengthening Uttar Pradesh’s Power Evacuation Network

Bengaluru, Jan 31: The Tata Power Company Limited (Tata Power), one of India’s largest integrated power companies, has successfully commissioned two critical 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, marking a significant milestone in strengthening the state’s power transmission infrastructure and enhancing grid reliability across the northern region.

The newly commissioned corridors—Mainpuri–Bara (380 circuit kilometres) and Mainpuri–Unnao (194 circuit kilometres)—have been developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project and form a vital part of Tata Power’s expanding national transmission portfolio. Together, these high-capacity lines create a robust 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 in partnership with ICICI Bank and global investors, represents a successful resolution of previously stressed power assets. Once operational, the two transmission corridors will enable the evacuation of over 3,000 MW of thermal power generated within the state, significantly improving grid stability while supporting Uttar Pradesh’s long-term energy security and industrial growth objectives.

Execution of the project involved complex engineering and large-scale resource mobilisation. The 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. The lines also traverse forest stretches and were executed in strict compliance with environmental, safety, and regulatory norms.

Despite these challenges, the project was delivered in line with Tata Power’s benchmarks for operational excellence, quality execution, and stringent safety standards, reinforcing the company’s credentials as a leading developer of high-voltage transmission infrastructure in India.

With the commissioning of these two 765 kV corridors, Tata Power’s operational transmission network now spans 5,312 circuit kilometres, with an additional 1,997 circuit kilometres under construction. This expanding portfolio underscores the company’s growing role in building and modernising India’s high-voltage transmission backbone at a time when enhanced grid capacity is critical to sustaining economic growth and supporting the country’s evolving energy landscape.
