Ethiopia has inaugurated the Grand Ethiopian Renaissance Dam (GERD), Africa’s largest hydroelectric project, marking a milestone in the country’s development ambitions but reigniting tensions with downstream neighbours Egypt and Sudan.
The $5 billion dam, built on the Blue Nile close to the Sudanese border, measures 1.8 kilometres in length and 145 metres in height. When fully operational, it is expected to generate more than 5,000 megawatts of electricity, a capacity that could transform Ethiopia into a regional power exporter.

Prime Minister Abiy Ahmed hailed the project as a “shared opportunity” for East Africa, describing it as central to his country’s drive to expand electricity access and accelerate economic growth. Ethiopia, with a population of around 120 million, remains one of the world’s largest countries where millions still lack reliable electricity.
Kenya’s President William Ruto and Somalia’s President Hassan Sheikh Mohamud attended the ceremony, signalling regional support for Ethiopia’s development ambitions. However, Egypt and Sudan, which rely heavily on the Nile for their water supplies were notably absent.
Concerns from Downstream Nations
Egypt and Sudan have long expressed unease over the GERD’s implications for water security. Egypt, home to 108 million people, depends on the Nile for about 90% of its freshwater needs and fears that rapid filling of the reservoir could reduce flows during drought years. Cairo has repeatedly cited colonial-era treaties that enshrined its share of the Nile waters, warning that the dam poses an existential threat.
Sudan has joined calls for a binding agreement on the dam’s filling and operation. While Khartoum acknowledges potential benefits such as improved flood control and access to cheap electricity, it insists on legal assurances before fully endorsing the project.
Diplomatic Efforts and Tensions
Over the past decade, multiple rounds of negotiations mediated by the African Union, the United States, and other international actors have failed to produce a binding settlement. Former US President Donald Trump once warned that Egypt could end up “blowing up the dam,” underscoring how seriously the dispute is regarded globally.
Despite the diplomatic deadlock, Ethiopia has pressed ahead. The filling of the reservoir began in 2020 and has been carried out in phases during rainy seasons to minimise downstream disruption. So far, independent monitoring suggests there has been no major reduction in river flows, partly due to favourable rainfall.
National Symbol for Ethiopia
For Ethiopians, the dam has become a powerful symbol of national pride and unity. The government has repeatedly stressed that the project was financed largely without foreign assistance, with the central bank covering 91% of costs and the remaining 9% raised domestically through bond sales and contributions from citizens.
Prime Minister Abiy Ahmed has framed the GERD as not only a national achievement but also a continental milestone, calling it a “great achievement for all black people.” Analysts note that, in a country often divided by ethnic conflict, the dam represents a rare unifying cause.
Future Prospects and Challenges
While the GERD’s energy potential is vast, challenges remain. Rural Ethiopia, where only about half of households are connected to the national grid, may not immediately benefit from the surplus electricity. The government has pledged to expand grid connections in tandem with the dam’s output.
On a regional level, the project highlights broader issues of transboundary water management. The United Nations Convention on the Law of Non-Navigational Uses of International Watercourses emphasises equitable use and the need to avoid significant harm to other riparian states. However, Ethiopia, Egypt, and Sudan continue to differ sharply on how those principles should be applied to the Nile.
The launch of the GERD underscores both Ethiopia’s determination to harness its natural resources and the unresolved tensions over the Nile’s future. Whether the project ultimately fosters regional cooperation or fuels further discord will depend on diplomacy and the willingness of all parties to compromise.
For now, Ethiopia is celebrating what it considers a historic achievement, while its downstream neighbours remain cautious, viewing the vast structure on the Blue Nile as both a source of opportunity and a looming challenge.
