Tata Power Commissions Strategic 765 kV Transmission Lines to Boost UP Grid Stability
The Tata Power Company Limited has successfully commissioned two strategic 765 kV Extra High Voltage (EHV) transmission corridors in Uttar Pradesh, marking a significant step toward strengthening the state’s power transmission network and improving grid reliability across northern India.
The corridors—Mainpuri–Bara, spanning 380 circuit kilometres, and Mainpuri–Unnao, covering 194 circuit kilometres—were developed under the South East UP Power Transmission Company Limited (SEUPPTCL) project. These assets form an essential backbone for reliable power transmission within Uttar Pradesh and across the northern grid, while expanding Tata Power’s national transmission footprint.
The project was acquired by Resurgent Power Ventures Pte. Ltd., a joint venture led by Tata Power, ICICI Bank and global investors, as part of the resolution of stressed power assets. Following commissioning, the corridors will enable the evacuation of over 3,000 MW of thermal power generated within the state, improving grid stability and supporting Uttar Pradesh’s long-term energy security objectives.
Execution involved complex engineering and extensive resource mobilisation. Construction required more than 42,000 metric tonnes of tower steel, approximately 6,900 kilometres of conductor stringing, and the completion of over 100 major crossings, including railway lines, rivers and existing transmission corridors. The project also passes through forest stretches and was executed in strict compliance with environmental and regulatory guidelines.
Despite the scale and complexity, the project was delivered in line with Tata Power’s benchmarks for operational excellence, safety and quality execution, reinforcing its credentials in transmission infrastructure development.
With the commissioning of these two corridors, Tata Power’s operational transmission network has expanded to 5,312 circuit kilometres, with an additional 1,997 circuit kilometres under construction, underscoring its growing role in modernising India’s power transmission backbone.
