About

The Tinau Hydropower Plant is a small run-of-river hydroelectric project located in Rupandehi District, Lumbini Province, Nepal. Situated along the Tinau River basin, the project was originally commissioned in 1978 but was recommissioned in 1983 following flood damage. It has an installed capacity of 1.024 MW generated by two 250 kW and one 500 kW horizontal Francis turbines. The plant operates with a gravity weir diversion dam measuring 63 meters in length and 10 meters in height. Water is conveyed through a 2.462 km headrace tunnel to a semi-underground surface powerhouse. The project supports local grid supply and was transferred to Nepal Electricity Authority after license expiry around 1980. Its design flow is approximately 2.5 m³/s, with a catchment area of roughly 1,081 km² extending to the Indo-Nepal border. The facility includes an underground desilting intake chamber and a penstock 50 meters long. Tinau Hydropower serves as a modest yet important renewable energy source within the Lumbini region.
