Ethiopia has officially launched the Grand Ethiopian Renaissance Dam (GERD), a project under construction since 2011 and now recognized as Africa’s largest hydroelectric facility. The launch on September 9, 2025, was celebrated in Addis Ababa, where Prime Minister Abiy Ahmed Ali hailed the project as a “monument of national pride”. Africa’s largest hydroelectric dam opens in Ethiopia, yet the milestone has also reignited long-standing disputes with Egypt and Sudan over control of the Nile waters.

Ethiopia’s Grand Ambition

Built along the Blue Nile in the Benishangul-Gumuz region, the GERD required about $5 billion to complete. Remarkably, 91% of financing came directly from the National Bank of Ethiopia, with the remaining 9% raised through citizen bonds and contributions. This domestic funding, achieved without any support from institutions like the World Bank or International Monetary Fund, transformed the dam into a symbol of sovereignty.

When fully operational, the GERD is expected to generate 5,150 megawatts of electricity. For now, two turbines producing 750 megawatts are online. This is a significant step in a country of over 120 million people, where nearly half of rural households still lack electricity access. The dam’s vast reservoir, which covers an area larger than Greater London, reflects both the scale of ambition and the heavy local costs.

Tension Builds as Egypt and Sudan Raise Objections

While Ethiopia frames GERD as a national victory, its neighbors see a looming crisis:

• Egypt, with a population of 108 million, relies on the Nile for nearly 90 percent of its freshwater. President Abdel Fattah el-Sisi has described the dam as an “existential threat.”
• Cairo continues to demand a legally binding agreement to regulate reservoir filling, citing historic treaties that Ethiopia rejects.
• Sudan has expressed concerns about water shortages but also acknowledges potential benefits, such as reduced flooding and access to cheaper electricity.

Mediation led by the African Union and supported at times by the United States has failed to secure an agreement.

Ethiopia’s Dam and the Balance of Power

The dam is not only about electricity – it is also a tool of regional influence. Ethiopia is exploring sea access through Eritrea and Somalia, a development watched closely by Cairo, given its own strategic stake in Red Sea trade routes.

Global mediators, including the United Nations, have tried to bridge divides, but as of today, both Abiy Ahmed’s government and Abdel Fattah el-Sisi’s administration remain unmoved in their positions.

Conclusion

Africa’s largest hydroelectric dam opens in Ethiopia, a historic moment for Ethiopia, but one that also deepens uncertainty across the Nile Basin. For Ethiopia, it is a symbol of independence and electrification. For Egypt and Sudan, it is a question of survival and stability.

The true legacy of GERD will hinge less on megawatts and more on diplomacy – whether leaders like Abiy Ahmed and Abdel Fattah el-Sisi can steer this colossal project toward cooperation rather than conflict.
