Africa’s largest hydroelectric power plant, is slated for inauguration in September 2025. With a staggering capacity of 5,150 MW and a construction cost of $5 billion, the GERD represents a monumental achievement for Ethiopia and the continent at large.
However, it has also been at the heart of a contentious dispute between Ethiopia, Egypt, and Sudan over the Nile River’s waters—a conflict that underscores the complex interplay of national interests, historical treaties, and regional identity in the Horn of Africa.
The GERD, formerly known as the Millennium Dam or “Project X,” has been a cornerstone of Ethiopia’s ambition to become a regional energy hub. The dam’s journey began decades ago, with its site first identified by the United States Bureau of Reclamation between 1956 and 1964 during Emperor Haile Selassie’s reign.
Political instability, including the 1974 coup, Somalia’s invasion in 1977–78, and the Ethiopian Civil War, delayed progress for years. It wasn’t until 2011 that the project gained momentum, with the Ethiopian government renaming it the Grand Ethiopian Renaissance Dam—a name that reflects its vision of national and continental renewal.
The dam’s scale is staggering. Once fully operational, it will generate 5,150 MW of electricity, making it one of the largest hydropower plants in the world. For Ethiopia, where millions still lack reliable access to electricity, the GERD promises to transform the energy landscape.
It will not only meet domestic needs but also enable Ethiopia to export power to neighboring countries, boosting its economy and fostering regional integration. The $5 billion price tag, roughly 7% of Ethiopia’s 2016 gross national product, underscores the country’s commitment to the project, which has been largely self-funded due to a lack of international financing—a challenge often attributed to Egypt’s historical influence over Nile water-sharing agreements.
The GERD’s completion is a milestone not just for Ethiopia but for Africa as a whole. As noted in a web result from hydropower.org, hydropower is the backbone of Africa’s electricity supply, providing 40% of power in the Sub-Saharan region. Yet, nearly 90% of the continent’s hydropower potential remains untapped—the largest proportion of unexploited capacity globally. With energy demand in Africa growing twice as fast as the global average, projects like the GERD offer a pathway to develop the continent’s economy using renewable and efficient energy sources.
The dam’s potential to generate clean energy aligns with global initiatives like the Africa–EU Green Energy Initiative, which pledged over €20 billion at COP28 to promote sustainable energy in Africa.
The Nile River, one of the world’s longest waterways, is a lifeline for the 11 countries in its basin, particularly Egypt, Sudan, and Ethiopia. Egypt, which relies on the Nile for 90% of its freshwater, has historically asserted control over the river’s resources, citing colonial-era agreements like the 1929 Anglo-Egyptian Treaty and the 1959 Agreement.
These treaties granted Egypt veto power over upstream projects and allocated the lion’s share of the Nile’s waters to Egypt and Sudan, leaving little for upstream nations like Ethiopia.
Ethiopia, however, was not a party to these agreements and has long rejected their legitimacy. The GERD, located on the Blue Nile—which provides 69% of the Nile’s annual flow between July and September—has become a symbol of Ethiopia’s determination to assert its rights to the river’s resources. For Ethiopia, the dam is a matter of sovereignty and development, a means to harness the Blue Nile’s potential for electricity generation and economic growth.

Egypt, on the other hand, views the GERD as an existential threat. Cairo fears that the dam’s reservoir, which can hold 74 billion cubic meters of water, will reduce downstream flows, jeopardizing agriculture, drinking water, and hydropower generation at Egypt’s own High Aswan Dam.
Successive Egyptian governments have threatened military action to protect their “right” to the Nile’s waters, with the issue often framed as a matter of national security. Sudan, caught between the two, has oscillated in its stance, balancing concerns about water security with the potential benefits of regulated flows and cheaper electricity from the GERD.
The dispute has drawn international attention, with the United Nations and other bodies urging cooperation. A UN official emphasizing that “well-planned hydraulic infrastructure on a shared river course can be a source of enhanced collaboration, and need not be a zero-sum game.”
As the GERD nears its September 2025 inauguration, the stakes are higher than ever. Ethiopia sees the dam as a triumph of self-reliance and a step toward energy security, while Egypt and Sudan continue to push for guarantees that their water supplies will not be disrupted. The international community, including the United Nations, has called for dialogue and cooperation, emphasizing that the Nile’s waters can be a source of collaboration rather than conflict.
The GERD’s success will depend not only on its engineering but also on the ability of Ethiopia, Egypt, and Sudan to navigate their differences. For Ethiopia, the dam is a symbol of African unity and green energy—a beacon of what the continent can achieve. For Egypt, it is a challenge to its historical dominance over the Nile, forcing a reckoning with the region’s colonial past. And for Africa as a whole, the GERD represents a test of whether shared resources can be harnessed for collective progress.
As the waters of the Blue Nile continue to flow, the world watches to see if the Grand Ethiopian Renaissance Dam will fulfill its promise—or deepen the divides in the Horn of Africa. One thing is certain: the GERD is more than a dam. It is a statement of intent, a challenge to the status quo, and a potential catalyst for a new era of African development.
