About

The Middle Marsyangdi Hydropower Station is a peaking run-of-river hydropower plant located in Lamjung District, Gandaki Province, Nepal. Commissioned in December 2008, it has a total installed capacity of 70 MW, generated through two vertical shaft Francis turbines. The project utilizes a daily pondage of approximately 5 hours to manage peak electricity demand. Situated on the Marsyangdi River, it features a combined concrete gravity and rock-fill dam with a crest length of 95 meters and a live storage volume of 1.65 million cubic meters. Its underground powerhouse on the right bank of the river operates with a gross head of 110 meters and a net head of 98 meters, designed for a total design flow of 80 m³/s. The project is owned and operated by Nepal Electricity Authority (NEA) and contributes significantly to Nepal’s national power supply system, with an average annual generation of nearly 400 GWh. After restoration work completed in mid-2024, the plant is fully operational at its rated capacity. The cumulative generation of the station has reached 1574.84 GWh till 2011/12 with a maximum generation of 425.34 GWh in the same year exceeding the designed generation of 397.59 GWh and target generation of 399.31 GWh. The station has contributed 10.18 % of the total energy share in INPS.
