- Capacity: 6 million cubic meters
Mukungwa Dam is another important hydroelectric project in Rwanda. Located on the Mukungwa River, this dam generates 12 MW of power, supporting both the northern regions of Rwanda and the national grid. The dam also provides irrigation for nearby farmlands, contributing to local agricultural productivity.
3. Rusumo Falls Hydroelectric Project (Shared with Tanzania and Burundi)
- Location: Eastern Province (Rwanda)
- River: Kagera River
- Power Output: 80 megawatts (MW) (Shared between Rwanda, Tanzania, and Burundi)
- Capacity: 25 million cubic meters
The Rusumo Falls Hydroelectric Project is a regional project shared by Rwanda, Tanzania, and Burundi. It harnesses the power of the Kagera River to generate 80 MW of electricity, with each country receiving an equal share. The dam is a vital cross-border initiative aimed at improving energy access in the region, supporting economic growth and regional cooperation.
4. Rukarara Hydropower Plant
- Location: Southern Province
- River: Rukarara River
- Power Output: 9.5 megawatts (MW)
- Capacity: 4.5 million cubic meters
The Rukarara Hydropower Plant is one of Rwanda’s smaller dams, but it plays an essential role in powering rural areas. Located on the Rukarara River, this dam produces 9.5 MW of electricity and supports the southern parts of the country. It also contributes to irrigation and water management in the surrounding areas.
5. Giciye Hydropower Plant
- Location: Western Province
- River: Giciye River
- Power Output: 8 megawatts (MW)
- Capacity: 3.2 million cubic meters
Giciye Dam, located on the Giciye River, is another hydroelectric project designed to provide renewable energy to Rwanda’s Western Province. The dam generates 8 MW of power and helps support the country’s energy needs while also contributing to local agriculture through irrigation projects.
6. Ntaruka Hydropower Plant
- Location: Northern Province
- River: Lake Burera
- Power Output: 11 megawatts (MW)
- Capacity: 3 million cubic meters
Ntaruka Dam, built in the 1950s, is one of Rwanda’s oldest hydropower plants. The dam utilizes water from Lake Burera to generate 11 MW of electricity. Despite its age, the dam remains a crucial part of Rwanda’s energy infrastructure, supplying power to the northern regions and regulating water levels between Lake Burera and Lake Ruhondo.
7. Rugezi Wetland Dam (Environmental Restoration Project)
- Location: Northern Province
- River: Mukungwa River (Fed by Rugezi Wetlands)
- Power Output: None
- Capacity: 2.5 million cubic meters
The Rugezi Wetland Dam is part of an environmental restoration project aimed at preserving the Rugezi Wetlands, which feed into the Mukungwa River. Although not a power-generating dam, it plays a critical role in water management, supporting irrigation, biodiversity conservation, and maintaining water levels in the wetlands. The project has had a significant impact on local agriculture and environmental sustainability.
8. Keya Hydropower Plant
- Location: Western Province
- River: Keya River
- Power Output: 2.2 megawatts (MW)
- Capacity: 1.5 million cubic meters
Keya Hydropower Plant is a smaller dam on the Keya River, designed to provide power to local communities in Rwanda’s Western Province. The dam generates 2.2 MW of electricity, making it an important source of renewable energy for rural areas. It also supports local agriculture by providing water for irrigation.
9. Cyimbili Micro Hydropower Plant
- Location: Western Province
- River: Sebeya River
- Power Output: 0.5 megawatts (MW)
- Capacity: 0.5 million cubic meters
Cyimbili is a micro-hydropower plant that plays an essential role in providing power to rural areas in Rwanda’s Western Province. The plant uses the Sebeya River to generate 0.5 MW of power, enough to support local homes and small industries. It also contributes to water management in the region.
10. Karongi Hydropower Plant
- Location: Western Province
- River: Karongi River
- Power Output: 2.6 megawatts (MW)
- Capacity: 1 million cubic meters
The Karongi Hydropower Plant, located on the Karongi River, is another small but significant source of renewable energy for Rwanda. The dam generates 2.6 MW of electricity and supports irrigation projects in the region. It helps supply electricity to rural communities, contributing to the country’s goal of expanding energy access across all provinces.
Conclusion
Rwanda’s commitment to harnessing its water resources through dam construction is a key part of its development strategy. Dams like Nyabarongo I, Mukungwa, and Rusumo Falls contribute significantly to the country’s energy supply, while smaller dams such as Keya and Cyimbili support rural electrification and water management. These projects also play a vital role in supporting agriculture through irrigation and flood control, ensuring that Rwanda continues to grow economically while promoting environmental sustainability.
