About

Sanjen (Upper) Hydroelectric Project (SUHEP) is a 14.8 MW peaking run-of-river hydropower project located in Chilime V.D.C., Rasuwa District, Nepal. It harnesses water from the snow-fed Sanjen River, featuring an overflow diversion weir, undersluice, desanding basin, peaking pond, and an underground headrace tunnel 1,386 meters long. The surface powerhouse hosts three horizontal-axis Francis turbines, each rated at 5.1 MW, with synchronous generators. The project was developed by Sanjen Hydropower Company Limited and commenced commercial operations on October 8, 2023. Power generated is transmitted through a 5 km, 132 kV line connected to the Chilime Hub, linking further to the 220 kV Chilime-Trishuli transmission corridor. The project supports cascade hydropower development by feeding tailwater to the downstream Sanjen Hydroelectric Project (SHEP). The design integrates stable geological formations of schist and quartzite, ensuring underground structures are well-supported. Its technical configuration enables reliable energy supply with seasonal variation management via peaking pondage.
