Upper Thulokhola Hydropower Project Connects 22.5 MW to National Grid

Electricity generated by the 22.5 MW capacity Upper Thulokhola Hydropower Project, developed by Thulokhola Hydropower Limited, has been successfully connected to Nepal’s central grid.

The milestone was achieved after completing the construction of the project’s physical infrastructure, installation of key equipment, and thorough internal testing. The project underwent a five-day testing period, which confirmed its operational readiness, said Project Chief Yadav. During the current dry season, the plant generated a total of 13.86 MW of electricity.

Construction of the hydropower project began in 2080 BS. Key components include a dam, a descender (water retention pond), a 2,900-meter main pipeline, and a 300-meter search shaft pipeline installed in Sugurthala. The powerhouse itself has been constructed in Phedi.

The project operates as a run-of-the-river hydropower system. Electricity generated at the site is transmitted via a six-kilometer-long 132 kV line from Phedi to Bandi. From there, power is integrated into the national grid through the 220 kV Dana-Khurkot transmission line via Tilkenichauar, extending connections to Thulokhola and Chimkhola-Mangale-Rahughat.

This development is expected to enhance electricity supply in the region and support Nepal’s growing demand for clean and sustainable energy.
