| A study on
all perennial rivers has been performed. The aim of the study was
to identify and estimate cost and production for all potential hydro
power projects in the Lower Kunene, Kavango and Lower Orange rivers.
The table below show all possible projects. The development price
in this table assumes that Epupa has already been developed. This
is because all later projects will benefit from infrastructure from
the Epupa project.

The following graph show
all potential and existing energy production in the three perennial
rivers sorted by the per unit cost. In this figure the Ruacana hydropower
station is included, and Epupa is assumed already constructed. As
can be deducted from the table and the figure, 5.500 GWh out of
a potential of approx. 7.000 GWh can be constructed at a price below
25Ncent/kWh.
