About the Teesta-V Project
The Teesta-V Hydro Electric Project, located on the Teesta River in East Sikkim, is a 510 MW operational hydropower plant that has been running under the ownership of (Green Energy). Commissioned in 2008, it is one of the largest hydroelectric plants in the Northeast region of India and plays a crucial role in regional power supply. The latest civil works awarded to Patel Engineering focus on improving water diversion tunnels, spillway capacity, and dam outflow systems to meet current and future hydrological challenges.
Scope of the Contract
Patel Engineering will be responsible for detailed construction of spillway tunnels, excavation of the tunnel portal, concrete lining, and installation of necessary hydraulic structures and safety components. This project will involve high-altitude tunneling and geotechnical expertise, areas in which Patel Engineering has proven capability through earlier works like the Subansiri Lower Hydroelectric Project. The works will follow advanced engineering protocols to withstand seismic activity and high-pressure flow conditions commonly encountered in Himalayan river systems.
Strategic Importance
The awarded contract forms part of NHPC’s broader push toward strengthening India’s hydropower ecosystem, especially in light of climate-induced shifts in river flow patterns. Projects like Teesta-V are essential to maintaining energy security in the north-eastern region, which relies heavily on hydropower for base load requirements. According to the hydropower is set to contribute significantly to India’s renewable mix as it provides grid balancing and energy storage advantages. Strengthening such infrastructure ensures disaster resilience and supports long-term water management goals.
Patel Engineering’s Portfolio and Role
Established in 1949, Patel Engineering is a leading player in civil construction with specialisation in hydroelectric, irrigation, and tunnelling projects. The company’s expanding portfolio includes challenging terrain projects across Jammu & Kashmir, Himachal Pradesh, Arunachal Pradesh, and Maharashtra. Its selection for this Sikkim-based work highlights its continued credibility in handling technically demanding contracts. More recently, Patel Engineering also worked on the Ranjit-IV Hydroelectric Project, showcasing its experience in Northeast India’s rugged landscapes.
Looking Ahead
This ₹239.98 crore contract reflects India’s commitment to modernising existing hydropower assets, ensuring climate resilience, and building infrastructure that aligns with As Patel Engineering takes on this critical task, the project is expected to not only bolster local employment but also contribute to safer, more efficient power generation from one of the country’s most strategically located river basins.
