Hydropower facilities / Hydropower plants (HPP)

Thakmo HPP

The 150 MW Thakmo HPP of diversion type is located in Phuong Long district of Binh Phuoc province and serves as the upper stage of the cascade on the Be River. The HPP was constructed during 1991-1995 and now is in operation. In 2000 units of Thakmo HPP were recertified to 82MW each and now installed capacity of the hydro project is 164 MW.

Thakmo HPP is the first project developed in co-operation between Ukrhydroproject PJSC and Vietnamese companies.

Scope of work envisaged under the contracts:
