Planned Developments in the
Zambezi Basin
Proposed Dams and Hydropower Projects
Water has many critical roles in the realization
of socio-economic development in southern
Africa. One such role is to provide hydropower
to help the region to meet its ever-growing
demand for energy. SADC Member States,
through the Southern African Power Pool
(SAPP), have thus planned to commission a
number of hydropower projects in the Zambezi
River Basin. The Basin is considered to have
enormous capacity to produce sufficient power
for the region if fully harnessed.
SAPP estimates that the Zambezi River has
the potential to produce more than 20 000
Megawatts (MW) of electricity (Tauya 2006).
However, only 23 per cent of this potential
is being harnessed, largely from two main
sites: the Kariba Dam between Zambia and
Zimbabwe, and the Cahora Bassa Dam in
Mozambique (SARDC 2009c). To fully exploit its
potential, various projects have been identified
for commissioning in the Zambezi Basin.
Batoka Gorge Hydropower Station
The Batoka gorge is located about 50 km
downstream of Victoria Falls between Zambia
and Zimbabwe. When operational, it has the
capacity to produce up to 1 600 MW. National
power utilities from the two countries are ready
to begin work on the project. However, limited
funding, environmental concerns and technical
challenges have stalled the process. Zambia and
Zimbabwe have also identified other sites on the
Zambezi River fromwhich they could jointly tap
electricity. These sites include the Devils Gorge
(1 200 MW), Mutapa Gorge (1 085 MW) and
Victoria Falls South (390 MW) (Tumbare, 2005).
