PROJECT COST	3,800,000,000.00
COMPLETION DATE	30/11/2022
PROJECT INFORMATION	*Artists impression​ The Caculo Cabaça hydropower plant project is a 2,172MW run-of-the-river hydroelectric facility under construction in Kwanza Norte Province of the Southern Africa country, approximately 19 kilometers upstream of the Laúca hydropower station and 270 kilometers east of Angola’s capital city Luanda. The project comprises the construction of a 103m-high concrete dam with a crest length of 553 meters. The maximum length of the reservoir will be 16.3 kilometers and an area of 16.6 km2 will be inundated. The dams’ storage capacity of 440 million cubic meters. The dam’s hydraulic structure includes a controlled frontal spillway with five radial gates and a flow rate of 10.02m3/s. The bottom outlet of the structure is formed by two-lined tunnels while its central body comprises two saddle dams, closed by concrete weirs, 525m and 192m long, and 36m and 4m wide respectively. The water intake structure for the Caculo Cabaça hydropower plant will be located about 2.4 kilometers upstream of the dam’s left abutment. The project also involves the construction of an underground powerhouse equipped with four 530MW turbine-generator units, as well as a 52MW ecological power plant situated adjacent to the dam. An estimated 10,000 workers are expected to be hired during the construction phase. PRIVATE / ENCRYPTED No
