Egypt Faces New Challenge as Ethiopia Plans More Nile Dams

Ethiopia is preparing to advance three additional hydropower projects on the Blue Nile—Karadobi, Mandaya and Beko Abo—creating a fresh challenge for Egypt after Cairo failed to stop the construction and operation of the Grand Ethiopian Renaissance Dam (GERD).

The three proposed projects could generate around 5,700 megawatts of electricity, although their designs and capacity could still change because they remain at the planning stage.

For Ethiopia, expanding hydropower is part of its strategy to increase electricity supply, support economic growth and improve energy security. However, Egypt is concerned about how additional dams could affect the Nile, particularly during periods of drought.

Egypt's main objective is now to secure agreements covering dam operations, water releases, drought management, information sharing and reservoir filling, rather than attempting to stop Ethiopia from building new dams altogether.

The GERD, inaugurated in September 2025, demonstrated the limits of Egypt's diplomatic pressure. Despite years of negotiations and objections from Cairo, Ethiopia completed the nearly $5bn project, which has an installed capacity of about 5,150 megawatts.

Sudan is also crucial to the dispute because it lies between Ethiopia and Egypt and is directly affected by changes to the Blue Nile. While Sudan shares some concerns with Egypt, it could also benefit from more predictable water flows and Ethiopian electricity. Its ongoing war, however, limits its ability to play a stronger diplomatic role.

Analysts say Egypt still has important diplomatic tools, including international alliances, international law and cooperation with Sudan, but its ability to prevent Ethiopia from developing additional hydropower projects is limited.

The new dams could therefore become another major test of relations between the three countries. 

A lasting solution would likely require greater transparency, advance notification, data sharing, flexible dam-management rules and agreements on how to respond to droughts and potential downstream impacts.
