About

The Gandak Hydropower Station is a canal-based run-of-river hydroelectric project located in Nawalparasi District, Narayani Province, Nepal. The plant utilizes the western irrigation canal of the Indo-Nepal Gandak Barrage on the Narayani River to generate electricity with a gross head of approximately 6 meters. Commissioned in April 1979 and handed over to Nepal in 1981, the project has an installed capacity of 15 MW distributed over three Kaplan turbines (5 MW each). It operates with daily peaking capability integrated into the irrigation system, generating approximately 106 GWh annually. Owned and operated by Nepal Electricity Authority (NEA), the project supports domestic energy demand and exports power to India via cross-border transmission lines. Renovations to upgrade electromechanical equipment are ongoing since 2022. Power generation is dependent on canal water availability, with scheduled canal closures twice per year for maintenance. The project exemplifies multi-purpose water resource use by combining irrigation and hydropower benefits under the Gandak River Agreement.
