The Capanda Dam ( Portuguese Barragem de Capanda ) dams the Cuanza River , which at this point forms the border between the provinces of Cuanza Sul and Malanje in Angola . The capital Luanda is about 360 km northwest of Capanda. A little north of the reservoir is the village of Pungo Andongo and the small town of Cacuso .

The project to build the dam began in 1982. The actual construction work began in 1987 and was carried out by the Brazilian company Odebrecht . However, the construction progress was repeatedly interrupted by the civil war in Angola . The dam is used to generate electricity. It is owned by the Empresa Nacional de Electricidade (ENE).

Barrier structure

The barrier structure consists of a concrete gravity dam with a height of 110 m. The length of the top of the wall is 1,200 (or 1,470) m.

The dam has both a bottom outlet and a flood relief . A maximum of 1,270 m³ / s can be discharged via the bottom outlet and the turbines, and a maximum of 7,760 m³ / s via the flood discharge. The design flood is 4,800 (or 6,400 or 9,700) m³ / s; the probability of this event occurring has been determined to be once in 100 (or 1,000 or 10,000) years.

Reservoir

With the normal storage target of 950 m (maximum 951.5 m at high water), the reservoir extends over an area of around 164 (or 170) km² and holds 4.8 billion m³ of water - of which 3.56 billion m³ can be used become. The minimum storage target is 917 m.

power plant

With an installed capacity of 520 MW, the Capanda power plant is currently (as of Feb. 2015) the largest hydropower plant in Angola . The average annual production is 3 billion kWh . The installed capacity of Capanda represents almost 30% of Angola's total generation capacity of 1,848 MW (as of May 2014).

The four Francis turbines in the power plant have a maximum output of 130 MW each. According to GEO, they were put into operation in 1999. The turbines are from LMZ Russia and the generators from Electrosila Russia . The power plant is operated by ENE.

The maximum height of fall is 84 m. The maximum flow rate of all turbines is 640 m³ / s.

Others

According to GEO construction costs amounted to 4 billion USD .

In 2012, drought caused the storage target in Capanda to decrease from 950 m to 927 m. As a result, electricity generation in the Capanda power plant fell to 240 MW and this resulted in daily power outages in the capital Luanda. In order to remedy this problem and to increase the proportion of the population with access to electricity (60% of the population are not connected to the electricity grid), the country's electricity production is to be expanded to 6,000 MW by 2017, including the construction of further hydropower plants on Cuanza heard.
