The mighty Congo River in the Congo DR is the second largest river in the world, because it winds itself through the rain forest of Africa. At 4,700 km the Congo is the world's third longest river. It flows gently westwards for most of its length through a plateau, to fall 300m in its last 350km dash to the ocean. It is 6000 to 8000 m in width at its widest point.
Near the outlet, 160 km from the Atlantic Ocean, the V-shaped deep gorge forms cataracts and rapids as shown by the map. It is very fast and narrow; the width is less than 800 m – an ideal location for helical turbines. A $24 million feasibility study is required which includes an experimental model, and this would produce 26 MW annually.
The next step is to develop the first power cell line, which will produce 500 MW with an estimated cost of $120 to $220 million, which is one quarter of the price of a nuclear power plant with the same power production.
The combination of water scarcity and hydro electrical production go hand in hand.
