tructures

The main structures of the project are a concrete gravity diversion dam of about convert|100|m|ft in length and convert|43|m|ft in height, an open surface desander, a headrace tunnel of about convert|6|km|mi in length and convert|7.4|m|ft in diameter, and a surface powerhouse. The rated discharge of 141 m³/s feeds the three turbines in the powerhouse. The reservoir has a surface area of convert|65|ha|m2, and is followed by a convert|5.3|km|mi-long back water level. Permanent camps are located at Beltari and Mirmi, in Shree Krishna Gandaki VDC, Syangja district.

Transmission line

The power generated by the three turbines is evacuated to the central grid via a 132 kV single circuit, a convert|66|km|mi long transmission line to Pokhara, and a convert|44|km|mi double circuit transmission line to Butwal. A sub-station has been constructed in Lekhnath Municipality, Kaski district and the existing Jogikuti substation in Butwal has been upgraded.
