Laúca Main Works, Angola

The construction of the Laúca Hydropower Project, with an installed total capacity of 2,067 MW, started in 2012. Six Francis-turbines are housed in an underground powerhouse. An additional smaller turbine is foreseen to utilize the minimum required ecological flow rate. The Laúca dam is a roller compacted concrete (RCC) type with a maximum height of 132 m and a crown length of about 1.1 km. mehr


Laúca Main Works, Angola

In 2013, The Angolan Government has started the construction of the Laúca Hydropower Project with a requested installed capacity of 2,067 MW, presently one of the largest hydropower projects in Africa. The underground powerhouse will house six vertical Francis turbines, each with a rated capacity of 334 MW. The minimum required ecological flow will be utilized for electricity generation in a second powerhouse (Ecological Powerhouse) located at the toe of the dam. This powerhouse will be equipped with a 67 MW Francis turbine. mehr


Laúca Main Works, Angola

The underground powerhouse of the 2,067 MW Laúca Hydropower Project is located approx. 2.4 km downstream of the dam. Six shafts (90 m height and 8 m diameter) below the intake towers located at the axis of the dam have been executed by using the raise-boring method and were lined with reinforced concrete. Most parts of the headrace tunnels and also the powerhouse cavern were executed by using conventional drill-and-blast method. Rock support consisted of fibre reinforced shotcrete, rock bolts and anchors. mehr

In 2013, The Angolan Government has started the construction of the Laúca Hydropower Project with an installed capacity of 2,067 MW, presently one of the largest hydropower projects in Africa. As a member of an International Consortium, Lahmeyer was contracted for the design review and supervision of the dam, hydraulic power circuit and the powerhouse, including the electro-mechanical equipment. Lahmeyer will give assistance during commissioning and initial operation as also for the supervision during the first year of the warranty period. mehr


Laúca Main Works, Angola

The dam of the Laúca Hydropower Project is a roller compacted concrete (RCC) type with a maximum height of about 132 m and a crown length of about 1.1 km, creating a 11 km2 large reservoir with a storage capacity of about 5.5 x 109m3. The integrated spillway is equipped with three radial gates, each 15 m wide and 21 m high. The bottom outlet, with a 6.70 m height, 3.60 m width and a length of 115 m, is located in the middle of the dam. mehr


Wasserkraftanlage Capanda, Angola

The construction of the Capanda dam was initiated in 1982, but due to military conflicts the works stopped in the 1990s. After the resumption of the construction works the first units started going into operation in 2004. The power station contains four Francis Turbines with a capacity of 130 MW each. The dam is a roller compacted concrete (RCC) type with a maximum height of 110 m. mehr
