Project Overview
Tadi Ghyangphedi Hydropower Project
The Tadi Ghyangphedi Hydropower Project (TGHPP) is an 8.0 MW run-of-river (ROR) hydropower project located in Dupcheswor Rural Municipality, Nuwakot, Nepal. The project utilizes the natural flow of the Tadi Khola River to generate renewable energy, supporting Nepal’s growing electricity demand. Designed with a focus on sustainability, TGHPP integrates modern hydropower infrastructure while maintaining ecological balance. The project aims to enhance energy security, improve local access to electricity, and contribute to Nepal’s hydropower sector development.
- Installed Capacity: 8.0 MW with an estimated annual energy production of 48.746 GWh.
- Project Location: Situated along Tadi Khola, within Dupcheswor Rural Municipality.
- Infrastructure: Includes a run-of-river system, headworks, powerhouse, and transmission line.
- Sustainable Approach: Designed for efficient energy generation with minimal ecological disturbance.
- Catchment Area: 53.76 km² at intake, 74.08 km² at powerhouse.
- Riparian Release: Maintains 10% of monthly flow to support aquatic life.
- Sediment Management: Settling basins designed to remove particles >0.15 mm.
- Eco-Friendly Development: Ensures long-term sustainability of the river ecosystem.
- Nearest Road Head: Gravel road up to Ghyangphedi (Powerhouse site), located 7 km from Ramati Bazaar.
- Distance from Kathmandu: 74 km via road to the project site.
- Additional Road Construction: 1 km of new road to the powerhouse and 1 km to the headworks from Selolo.
- Geographical Coordinates:
- Latitude: 27°58’31” N to 28°00’40” N
- Longitude: 85°26’34” E to 85°27’51” E
