About

The Sun Koshi Hydropower Station is a run-of-river daily-pondage hydroelectric plant located in Sindhupalchok District, Bagmati Province, Nepal. Commissioned in 1972, it harnesses water from the Sun Koshi River with a catchment area of approximately 4,812 km². The plant has an installed capacity of 10.05 MW, delivered by three Francis-type turbines each rated at 3.35 MW. Water is diverted through a lateral intake with under-sluice gates and conveyed via a canal to a settling basin, followed by penstocks feeding the surface powerhouse. The design discharge is around 39.9 m³/s. The plant’s annual energy generation averages about 70 GWh, with higher production during the monsoon and reduced output in the dry season. The facility is owned and operated by the Nepal Electricity Authority (NEA) and is a significant contributor to the regional grid.
