About

The Chilime Hydropower Plant is a peaking run-of-river project located in Rasuwa District, Nepal. Commissioned in August 2003, the plant has an installed capacity of 22.1 MW, generated by two horizontal axis Pelton turbines. The project harnesses the hydropower potential of the Chilime River with a gross head of 351.5 meters and a net head of 337.46 meters, using a design flow of 7.5 m³/s. Featuring an underground powerhouse, the facility includes a surge tank and a pressure shaft/penstock extending over 635 meters. The electricity generated is sold in bulk to Nepal Electricity Authority (NEA) under a power purchase agreement. Chilime Hydropower Company Limited, which owns the plant, is majority-owned by NEA (51%). The project contributes approximately 150 GWh annually to Nepal’s electricity grid. Its 38 km 66 kV transmission line connects it to the national grid. Located about 133 km from Kathmandu, the plant plays a key role in regional energy supply and development.
