DORJILUNG
Hydropower Project

Dorjilung hydropower is located in the Himalayas on the Kurichhu river, about 450 km east of Thimpu.
The planned HPP (IP = 1125 MW) develops the hydropower potential of the river (DH = 306 m, Q = 287 m3/s) located just upstream the reservoir of the existing Kurichhu hydropower plant (IP = 60 MW).
