Description for Ruzizi's Transmission System (Africa)

The Ruzizi Transmission System's project was created with the aim of contributing to a reliable and cost-efficient power supply to the South Kivu in DRC, Rwanda and Burundi. The studies consist of engineering services relevant to the transmission lines and the Kamanyola dispatching centre for the evacuation of the energy produced by the Ruzizi III hydropower plant, as well as the Ruzizi I and Ruzizi II civil rehabilitation works.

The works covered by the project will significantly contribute to the development of the ECGLC region’s interconnected network.

In fact, the Ruzizi III - Kamanyola and Ruzizi III - Kibuye HV lines will promote the distribution and transmission of energy over great distances thereby increasing electricity access and supply at a lower cost.

The project consists of the realization of full engineering services, from feasibility to detailed design and bidding documents, concerning the 220 kV transmission lines, Ruzizi III - Kamanyola and Kamanyola-Kibuye, the Kamanyola regional Load dispatching Centre, the Cascade coordination Centre of the Ruzizi river as well as the Rehabilitation of Ruzizi I and Ruzizi II hydropower plants’ civil works.

The Kamanyola regional dispatching centre will manage power flows through the ECGLC region by strengthening the grid reliability and promoting the establishment of a regional energy market.

The Cascade Coordination Centre of the Ruzizi River, located in Kamanyola, will optimize the use of the river's resource by way of hydroelectric power plants.
