The Bhilangana Hydro Electric Project, developed in two separate stages — Stage-I at Ghansali and Stage-III at Ghuttu in the Tehri Garhwal district of Uttarakhand — represents a comprehensive cascade hydropower development on the Bhilangana River, a major tributary of the Bhagirathi. The civil works for both stages encompassed the construction of diversion weirs, desilting basins, head race tunnels driven through the Garhwal Himalayan rock formations, surge shafts, underground powerhouses, and tailrace systems, all executed in a region known for its steep gorges, seismic activity, and unpredictable river behavior during monsoon seasons.

The successful completion of Stage-I and Stage-III of the Bhilangana HEP has established a robust cascade power generation system that collectively enhances the renewable energy output of Uttarakhand, providing clean hydropower to the northern grid. Beyond energy generation, the projects have contributed to regional development by creating employment, improving local infrastructure, and supporting the state’s vision of sustainable utilization of its abundant river resources. The engineering achievements at Bhilangana stand as a testament to the capability of executing complex hydropower projects in challenging Himalayan terrain with high standards of quality and safety.
