The Sanjen Hydroelectric Project is a 42.5 MW cascade-type run-of-river scheme located in Chilime VDC of Rasuwa District, Bagmati Province, Nepal. Developed by Sanjen Jalavidhyut Company Limited (SJCL), the project utilizes the tailwater of the Upper Sanjen Hydropower Plant as its intake. The project is designed with a gross head of 442 m and a net head of 433 m, with a combined design discharge of 11.57 m³/s, including 0.5 m³/s from the Chhupchhung stream. It features a 3.63 km D-shaped headrace tunnel, a restricted orifice surge tank (51 m high), and a 1.02 km long penstock pipeline. Power is generated using three vertical-axis Pelton turbines (15 MW each), paired with synchronous AC generators (16.85 MVA each). The surface powerhouse evacuates electricity via a 132 kV, 1.5 km transmission line to the national grid. The project generates approximately 251.94 GWh annually, with 241.86 GWh as salable energy. It is one of Nepal’s key hydropower developments with total investment costs of NPR 5.02 billion as of December 2011. The project is part of a broader cascade system in the Trishuli River basin, enhancing regional energy output through integrated river utilization.
