Project Description

According to the ADB document, "the Upper Trishuli-1 Hydropower Project involves the construction and operation of a 216 MW greenfield run-of-the-river hydropower facility located in the Trishuli watershed, 275m downstream of the confluence with the Bhotekosi river, and about 70km north of Kathmandu. The Project consists of a 77m wide diversion dam by which the water will get diverted through a 9.8km long headrace tunnel to an underground power station. The electricity generated will be sold for domestic consumption to the Nepal Electricity Authority (NEA) based on a fixed tariff structure. The 35 year concession will be on a BOOT basis and includes a 5 year construction period."

"The Project will connect to the Chilime–Trishuli transmission line via a 689-metre extension from the Project switchyard. The Project will be accessed via existing public roads, but NWEDC will construct an 11.84-kilometre private road upstream along the river to access the UT-1 dam. The Project design was changed in response to the 2015 earthquake to strengthen its geotechnical
and seismic design, take into account updated climate change forecasts, adjust to changes inlandscape conditions (e.g. landslides), and to optimize engineering aspects of the dam.
The Project will take approximately 5 years to construct and will employ about 1,090 workers."
