About

Marsyangdi Hydropower Station is a peaking run-of-river hydropower project located in Tanahun District, Bagmati Province, Nepal, situated on the right bank of the Marsyangdi River near Aanbu Khaireni VDC. Commissioned in 1989, the plant has an installed capacity of 69 MW generated by three vertical Francis turbines rated at 26 MW each. The project features a 7.2 km concrete-lined headrace tunnel and steel-lined penstocks supplying water from a concrete weir diversion dam. The plant uses a maximum gross head of 90.5 meters with an average annual river discharge of 210 m³/s and a daily pondage volume of approximately 1.5 million cubic meters. Energy generated (approximately 462.5 GWh annually) contributes around 10.67% to Nepal’s total installed power system (INPS). Power is transmitted over a 132 kV line spanning 108 km linking Balaju and Bharatpur substations. Owned and operated by Nepal Electricity Authority (NEA), Marsyangdi is one of Nepal’s major hydropower assets supporting the national grid with peaking capabilities.
