Configuration: 4 X 130 MW Francis
Operation: 2004-2007
T/G supplier: LMZ, Electrosila
EPC: Odebrecht, Furnas, COBA, Hydroproject Inst, Technopromexport
Quick facts: Capanda was Angola’s largest civil engineering project of the time. The site is on the Rio Kwanza at the border of Kwanza-Norte and Malanje provinces. Development started in 1982 and, with $750mn from oil sales, and Odebrecht, Furnas, and TPE started on the project in Jan 1985 with operation then scheduled in 1991. This soon slipped to Dec 1993 and the plant site was occupied by UNITA from Nov 1992 until Dec 1994. Then the 110m dam was damaged and rehabilitation did not start until 1998, a process interrupted by another attack in 1999. Construction re-started in Jan 2000. At one point, there were 3,000 workers mobilized at the site. A 2,000m aircraft runway was built along with power, potable water, and sewage facilities. Reservoir filling began in late Aug 2002 and the first two units were finally commissioned in June 2004 followed by Units 3&4 in June 2007. The plant is connected to the Cambambe Substation via a 120km, 220kV transmission line which cost $218mn. The cost of war damage to the project is estimated to be at least $400mn and the total project cost has been estimated to be as much as $4bn.
