After GERD, can Egypt shape Ethiopia’s next Nile dams?

[File: Amanuel Sileshi/AFP]By Al Jazeera staffPublished On 21 Aug 202621 Aug 2026Egypt’s response to Ethiopia’s new Nile dam plans is centred on diplomacy, international pressure and cooperation with Sudan, rather than trying to stop construction outright. However, the experience of the Grand Ethiopian Renaissance Dam (GERD) has exposed the limits of Cairo’s influence.

The revival of three proposed Blue Nile hydropower projects – Karadobi, Mandaya and Beko Abo – will test whether Egypt can turn more than a decade of opposition into practical leverage over how Ethiopia develops the river.

The projects have been discussed for years. A 2024 academic study drawing on Nile Basin Initiative-sponsored work listed all three among proposed Blue Nile projects and noted that Karadobi and Beko Abo were considered alternatives in one potential three-dam configuration.

What is new is Ethiopia’s reported move to advance them. In March, the country’s Water and Energy Ministry announced plans for the projects, according to subsequent reporting. Their combined generating potential has been reported at about 5,700 megawatts, although the figures and specifications could change because the projects remain at the planning stage.

The announcement came months after Ethiopia inaugurated the GERD in September 2025, despite years of objections from Egypt.

For Ethiopia, developing the Blue Nile is closely tied to electricity generation, economic growth and energy security. Addis Ababa argues that expanding hydropower is essential for a country where millions of people have historically lacked reliable access to electricity.

The three projects fit into that wider strategy. However, their eventual impact on Egypt and Sudan will depend on what Ethiopia builds and how the facilities are operated.

Ezekiel Gebissa, an Ethiopian professor at Kettering University in the United States, told Al Jazeera that the consequences would depend on the scale and purpose of the projects. “Smaller dams could generate electricity for local communities without significantly reducing the volume of water reaching downstream countries,” he said, while projects linked to large-scale irrigation could have greater implications for Egypt and Sudan.

The impact will depend on various factors, including reservoir size, filling schedules, water releases and operating rules. A dam designed mainly for electricity generation would have different consequences from one linked to large-scale irrigation.

For now, the projects represent a potential new source of tension rather than proof that they will reduce the water reaching Egypt.

For Egypt, the Nile is the country’s main source of freshwater. Any major change upstream is viewed through the lens of national security.

Cairo’s concern is not Ethiopia generating electricity. It is what happens when water is stored and managed upstream, particularly during periods of drought. Egypt has therefore pushed for rules covering dam operations, drought management, water releases and information sharing.

Last September, Egypt again raised the issue at the United Nations Security Council, arguing that Ethiopia’s inauguration and operation of the GERD violated its international obligations and called for a binding agreement. Those were Egypt’s stated legal and political positions, not findings by the council.

The dispute reflects two different priorities. Ethiopia views the Blue Nile as a resource for development, while Egypt seeks guarantees over the water flows on which it depends.

The GERD demonstrated both the reach and the limits of Egypt’s diplomatic strategy.

Ethiopia inaugurated the dam on September 9, 2025, after years of negotiations with Egypt and Sudan failed to produce the binding agreement Cairo wanted. The nearly $5bn project, funded largely by Ethiopia itself, has an installed generating capacity of about 5,150 megawatts and is now a major part of Ethiopia’s electricity system.

For Egypt, the lesson was clear: diplomatic pressure could raise international attention but could not prevent Ethiopia from completing the project.

The focus has therefore shifted. Instead of trying to stop a single dam, Cairo is now seeking a role in how existing and future projects are designed, filled and operated.

Sudan remains central to Egypt’s approach because it lies between Ethiopia and Egypt and is directly affected by developments on the Blue Nile.

However, Khartoum is not simply aligned with Cairo.

Sudan could benefit from more predictable river flows and Ethiopian electricity, while also seeking greater transparency, information sharing and safeguards around upstream projects.

Mekki Elmograbi, a Sudanese governance expert, said transparency from Ethiopia was the starting point for cooperation. “Ethiopia must share more information with Sudan and Egypt; transparency is the first step toward cooperation,” he told Al Jazeera. “Who knows whether the new projects are good or bad for Sudan if there is not enough information?”

Elmograbi said Sudan should seek cooperation with both Ethiopia and Egypt to ensure major projects do not harm its interests. But Sudan’s ability to play a larger diplomatic role is constrained by its ongoing war.

While Sudan shares some concerns with Egypt, it also has its own relationship with Ethiopia and its own priorities, including access to electricity and effective management of the river.

Egypt’s strategy has centred on diplomacy, international pressure and cooperation with Sudan, aimed at pushing Ethiopia towards greater transparency and negotiated rules.

The experience of the GERD shows that Cairo’s strongest tools are political and diplomatic rather than coercive. Egypt can raise international attention, seek support from regional partners and push for agreements on issues such as data sharing, drought management and dam operations.

The challenge is that these tools are unlikely to give Egypt the ability to stop Ethiopia from pursuing new hydropower projects or to control decisions made in Addis Ababa.

Horn of Africa analyst, Abdiwahab Sheikh, told Al Jazeera that Egypt has “meaningful but limited leverage” over Ethiopia. He said Cairo’s strongest tools are diplomacy, alliances, international law and coordination with Sudan, while economic pressure is weaker and military coercion carries significant risks.

The three Blue Nile projects will test whether Egypt can convert diplomatic pressure into practical influence. For Sheikh, the path forward lies in negotiated rules rather than confrontation.

“A practical arrangement is possible if Ethiopia, Egypt and Sudan accept transparent information exchange, advance notification, adaptive dam-management rules and mechanisms for addressing droughts and downstream impacts.”
