The Upper Tamakoshi Hydroelectric Project is a 456 MW peaking run-of-the-river hydroelectric project in Nepal.[1] It is the largest hydroelectric project in Nepal, operating since July 2021.[2][3] It is sited on the Tamakoshi River (also spelled Tama Koshi), a tributary of the Sapt Koshi river (also spelled Saptakoshi), near the Nepal–Tibet border.
The Upper Tamakoshi Hydroelectric Project was a Nepal national priority project. When it is operated at full capacity, it is the largest hydroelectric plant in Nepal, with a power output equivalent to two-thirds of Nepal's current power generation.[4][5] The project was entirely financed from domestic financial institutions and companies.
