ANDRITZ Hydro has signed a contract for the electrical and mechanical works of the Da Nhim Upper 3 hydro­power project with Toan Thang Dat JSC (Vietnam). The scope of supply comprises design, engineering, manufacture, supply and supervision of installation, as well as commissioning of the complete electro-mechanical equipment.

With an output of 9.35 MW, the run-of-river power station on the Da Nhim River basin is in Lam Dong province in Vietnam’s Central Highlands (Tay Nguyen) region.

Da Nhim Upper 3 project will be the first Compact Axial Turbine (CAT) project to be developed in Vietnam. In comparison with the originally planned Francis turbine, the CAT solution is more efficient and provides better part-load performance under the natural conditions found at the plant. This results in better annual energy generation and higher revenue for the customer.

This project is a repeat order following ANDRITZ Hydro’s successful execution of the customer’s first hydropower project (Da Cho Mo 2 HEPP, 5.5 MW), which has been in commercial operation since November 2019.
