How Africa's mega dams and hydropower projects reshape the continent | DW News

Key Concepts:

• Energy gap in Sub-Saharan Africa
• Hydroelectric mega dams
• Transboundary water management
• Regional cooperation and interdependence
• Electricity export and shared benefits

1. The Energy Gap in Africa and the Potential of Hydroelectric Dams

• As of 2023, nearly 600 million people in Sub-Saharan Africa lack access to electricity, highlighting a significant energy gap.
• The World Bank suggests that hydroelectric mega dams could be a solution to address this energy deficit.
• The success of these projects hinges on trust and regional teamwork among involved nations.

2. Grand Ethiopian Renaissance Dam (GERD): A Case of Contested Waters

• GERD, built on the Blue Nile, is Ethiopia's initiative to resolve its energy shortages.
• Egypt fears the dam's impact on its Nile water supply, which is crucial for agriculture and survival.
• Negotiations between Ethiopia and Egypt have faced numerous obstacles, leading to heightened tensions.
• Former US President Donald Trump once suggested Egypt should "blow up the dam," reflecting the severity of the dispute.
• Despite the tensions, Ethiopia has signed agreements to export electricity to Sudan and Djibouti, indicating the potential for shared benefits to overcome mistrust.

3. Kariba Dam: A Success Story of Cooperation

• Located on the Zambezi River, Kariba Dam is jointly managed by Zambia and Zimbabwe.
• The Kariba Dam serves as a rare success story in cross-border water management.
• The joint river authority ensures the turbines keep running even during droughts, demonstrating the effectiveness of cooperation.
• The Kariba Dam exemplifies how cooperation can maintain electricity supply.

4. Swapi Hydropower Station: Shared Grids, Shared Interests

• Located in Guinea, the Swapi Hydropower Station has transformed the country from struggling to power its towns to exporting a third of its electricity.
• Guinea now exports electricity to Senegal, Gambia, and Guinea-Bissau.
• The Swapi Dam has fostered shared interests through interconnected grids, promoting regional interdependence.

5. Grand Inga Dam: A Future Powerhouse

• The Grand Inga Dam, planned for the Democratic Republic of Congo (DRC), has the potential to be the world's largest power-producing dam, surpassing China's Three Gorges Dam.
• South Africa and Nigeria have already committed to purchasing electricity from the Grand Inga Dam upon completion.
• In the DRC, where 80% of the population lacks access to electricity, the Grand Inga Dam could be a transformative project for the economy and Africa's energy network.

6. Conclusion

• Africa's mega dams, from the Nile to the Zambezi to the Congo, represent more than just infrastructure projects.
• With wise management, these dams can transform shared waters into shared futures.
• They have the potential to bridge borders, power cities, and unite nations through regional cooperation and interdependence.
