About

The Namarjun Madi Hydropower Project is a run-of-river hydropower facility situated in the Western Development Region of Nepal, within Gandaki Zone, Kaski District. It utilizes the flow of the Madi River near the Namarjun and Sildujure VDCs. The project features an installed capacity of 12 MW, supplied by two vertical axis Francis turbines rated at 6,250 kW each. The plant exploits a gross head of 63 meters and harnesses an average annual energy output of about 66.34 GWh after accounting for outages. Key infrastructure includes a 44-meter-long boulder-lined diversion weir, side intake structures, a 1,248-meter RCC rectangular headrace canal, a 144-meter steel-supported penstock with a 2.9 m internal diameter, and a surface powerhouse building. Power evacuation is planned via an 18 km, 132 kV double circuit transmission line from the powerhouse to Lekhanath. The project incorporates advanced electro-hydraulic PID governors and salient pole synchronous generators with brushless excitation. It is located approximately 2 km from new approach roads with an additional 5 km upgrading planned.
