- Power Output: 210 megawatts (MW) (Planned)
- Capacity: Estimated at 300 million cubic meters
The Kalungwishi Hydroelectric Project is a proposed dam that will generate 210 MW of electricity once completed. Located in northern Zambia on the Kalungwishi River, the project will play a key role in providing electricity to the rural northern region. It will also support irrigation and water supply initiatives.
6. Lunsemfwa Hydroelectric Power Station
- Location: Central Province
- River: Lunsemfwa River
- Power Output: 24 megawatts (MW)
- Capacity: 80 million cubic meters
The Lunsemfwa Dam, located on the Lunsemfwa River, is a smaller dam that generates 24 MW of electricity. It is an important source of power for the Central Province, helping to supply both residential and industrial areas. The dam also plays a role in irrigation and flood control in the Lunsemfwa River Basin.
7. Mulungushi Dam
- Location: Central Province
- River: Mulungushi River
- Power Output: 30 megawatts (MW)
- Capacity: 378 million cubic meters
Mulungushi Dam is located on the Mulungushi River and generates 30 MW of electricity. It is a key power source for the central part of Zambia, particularly for the mining and agricultural sectors. The dam’s reservoir also supports irrigation and water supply for local communities and industries.
8. Chavuma Falls Hydroelectric Project (Proposed)
- Location: Zambezi River, Northwestern Province
- River: Zambezi River
- Power Output: 15 megawatts (MW) (Planned)
- Capacity: Estimated at 100 million cubic meters
The Chavuma Falls Hydroelectric Project is a proposed dam on the Zambezi River in Northwestern Zambia. Once completed, it will generate 15 MW of electricity, primarily for local consumption in the region. The dam will also support small-scale irrigation projects, providing water for agriculture in the surrounding areas.
9. Lusiwasi Dam
- Location: Eastern Zambia
- River: Lusiwasi River
- Power Output: 12 megawatts (MW)
- Capacity: 61 million cubic meters
Lusiwasi Dam is located on the Lusiwasi River and generates 12 MW of electricity, supplying power to Eastern Zambia. The dam also plays a significant role in water supply and irrigation, supporting agricultural activities in the region. The reservoir helps mitigate the impact of seasonal droughts by providing a consistent water supply.
10. Mambilima Hydroelectric Project
- Location: Luapula Province
- River: Luapula River
- Power Output: 40 megawatts (MW)
- Capacity: 200 million cubic meters
Mambilima Dam is located on the Luapula River and generates 40 MW of electricity. The dam is a key power source for the Luapula Province, and its reservoir provides water for local communities and industries. The dam is also used for flood control, helping to regulate the flow of the Luapula River.
Conclusion
Zambia’s dams play a critical role in the country’s economic development, supporting hydropower generation, irrigation, and water supply. Major projects like Kariba, Kafue Gorge Upper, and Itezhi-Tezhi contribute significantly to Zambia’s energy needs, while smaller dams like Mulungushi and Lunsemfwa provide local power and water resources. As Zambia continues to grow, investments in dam infrastructure, particularly in the hydroelectric sector, will be crucial for ensuring sustainable energy production and water management. These dams are not only vital for energy generation but also for supporting agriculture and enhancing water security across the country.
