KOSSOU HYDROELECTRIC PLANT, IVORY COAST

The Kossou hydroelectric plant on the Bandama River in Ivory Coast is one of the country's main renewable energy projects aimed at improving the national energy supply. Built in the 1970s, it represents one of the poles of economic development in Ivory Coast and consists of a rockfill dam with an impermeable core and filters, an outdoor power plant, three tunnel penstocks, intake works, surface spillway, and various complementary works.

The dam has a crest length of 1,500 meters and a maximum height of 57 meters. The crest elevation is 209 meters, with a total volume of 5.4 million cubic meters of embankment.

The Kossou plant aims to harness the water resources of the Bandama River to generate sustainable electricity, contributing to reducing dependence on fossil fuels and diversifying Ivory Coast's energy mix. The dam creates the country's largest artificial lake, Lake Kossou, and also provides other benefits such as agricultural irrigation, fishing, and flood control.

The energy produced by the Kossou hydroelectric plant is essential for supporting the country's economic growth, improving access to electricity in rural and urban areas, and promoting sustainable development in Ivory Coast.
