The Ruzizi I hydroelectric dam was built at the Ruzizi River outlet from Lake Kivu in 1958, affecting the level and outflow of the lake. The dam delivers electricity to Bubanza and Kigoma via the Mururu substation, and is believed to have an optimal capacity with the present infrastructure, of generating 148 GWh annually.
The Ruzizi II power station was added in 1989. Ruzizi I and II are operated by a tri-national company Burundi, Rwanda and Democratic Republic of the Congo but electricity production is insufficient to meet the needs of the adjacent areas of these three countries and a further dam, Ruzizi III, situated about 25 km downstream is planned.
The project represents the first public-private sector energy engagement in the Great Lakes region.
