Studies, designs and construction drawings for the dam rehabilitation and the construction of the power plant and substation were carried out by COBA, in association, who was also responsible for the project management and construction supervision.

The dam is located in the Province of Huambo, south of the Province capital, on the Cunene River. Completed in 1975, the dam was subject to sabotage actions between 1986 and 1990 which lowered the level of exploitation.

The project considered the construction of a power plant at the toe of the dam, with an installed capacity of approximately 60 MW, equipped with three Francis vertical axis units.

The estimated annual energy generation is about 150 GWh.
