How Ethiopia’s new dams test Egypt’s ability to defend its Nile red lines

A decades-old conflict between Cairo and Addis Ababa intensified this month as Ethiopian leaders pledged to advance three new Blue Nile hydropower dams. 

Ethiopia’s Ministry of Water and Energy announced in March that it was reviving plans for three hydropower dams along the Blue Nile. The three dams — Karadobi, Mandaya and Beko Abo — planned upstream from the Grand Ethiopian Renaissance Dam (GERD) are projected to generate about 5,700 megawatts combined, slightly more than the GERD’s installed capacity of 5,150 MW. 

Tensions escalated this month when Ethiopian Minister of Water and Energy Habtamu Itefa and Egyptian Foreign Minister Badr Abdelatty reasserted their governments’ competing claims. Egypt’s state-owned outlet MENA first reported on the dispute Aug. 16, citing Ethiopian officials who asserted “control” over water resources and full rights to build new dams. In an Aug. 20 interview with Al Arabiya, Abdelatty emphasized that no further unilateral dam construction would be tolerated. Itefa was equally firm in an Aug. 20 interview with Ethiopian government-affiliated outlet Pulse of Africa, saying Addis Ababa built the GERD “without the permission” of Cairo and would keep building “whenever the needs arise.”

The dispute traces back to Ethiopia’s 2011 unilateral decision to build the GERD and to competing claims over Nile water rights. Cairo cites colonial-era agreements from 1929 and 1959 that granted Egypt and Sudan a majority share of the river’s flow; Ethiopia, which was not party to either agreement, has long rejected them as illegitimate. Years of talks mediated by the African Union and the United States have failed to produce a binding deal. The GERD began full operation in September 2025.

Ethiopia’s regional realignment

The World Bank reported in 2025 that 60 million Ethiopians — more than 40% of the population — lack access to electricity, and Addis Ababa has pushed hydropower expansion in part to close that gap. “The GERD’s stated core goal is universal electricity access by 2030,” said Areig Elhag, a Sudanese researcher and analyst at the Washington Institute for Near East Policy.

Beyond its borders, Ethiopia’s expanding hydropower capacity has reshaped regional energy relationships and strengthened Addis Ababa’s influence across the Horn of Africa. At the GERD’s September 2025 inauguration, the presidents of Djibouti, Kenya, South Sudan and Somalia were among the African leaders in attendance. Kenyan President William Ruto hailed the project as evidence of Africa’s ability to “shape its own destiny,” while South Sudanese President Salva Kiir described it as a source of pride for Ethiopia and the wider region, according to Ethiopian state media. Ethiopia now exports electricity to Kenya, Djibouti and Sudan, according to the US Commerce Department, positioning the nation as an emerging regional energy hub.

This shift is most evident in the Horn of Africa. On Jan. 1, 2024, Ethiopia signed a memorandum of understanding with Somaliland — a self-governing territory that Somalia considers part of its sovereign territory — under which Ethiopia would lease 20 kilometers (12 miles) of coastline around the port of Berbera for 50 years for naval and commercial purposes, according to Reuters.

In October 2024, the presidents of Somalia, Egypt and Eritrea met in Asmara and agreed to deepen security cooperation while emphasizing respect for Somalia’s sovereignty and territorial integrity. Reuters described the summit as leaving Ethiopia more isolated regionally amid its dispute with Somalia and longstanding tensions with Egypt over the Nile.

Regional tensions escalated further on Dec. 26, 2025, when Israel became the first country to formally recognize Somaliland as an independent and sovereign state, according to Reuters. Somalia rejected the decision, while Egypt, Turkey, Djibouti and the African Union also criticized the move, which added another outside power to an increasingly contested geopolitical landscape in the Horn of Africa and Red Sea region.

“This announcement of the potential plans for these three dams should be a wake-up call,” Timothy Kaldas, deputy director of the Tahrir Institute for Middle East Policy, told Al-Monitor. It is “essentially the type of negative fallout of the precedent set by GERD that Egypt has been worried about; that it is not going to just be GERD, that it will be other projects developed on the Nile.”

Downstream fallout

To Egyptian officials, that precedent poses an existential threat. Abdelatty told Al Arabiya that Cairo would not accept any agreement that fails to guarantee Egypt’s share of water, which he said barely meets 60% of the country’s yearly needs, and that relations with Ethiopia must balance “[Ethiopia’s] right to development and Egypt’s right to exist.”

In Egypt, approximately 95% of the population lives and works on about 5% of the country’s land, according to the World Bank, with much of the population concentrated along the Nile Valley and Delta. The North African country’s growing population has also pushed Cairo to develop desert land for agriculture, placing additional pressure on already scarce water resources.

The Nile accounts for more than 97% of Egypt’s annual renewable water supply, according to the Organisation for Economic Co-operation and Development, while rainwater accounts for only about 2.2% of the country’s freshwater supply. Egyptian officials therefore fear that an expanded Ethiopian dam network could restrict downstream flows during prolonged droughts, threatening agricultural production and the livelihoods of millions in a country where scant and unpredictable rainfall provides little buffer against reduced Nile supplies.

Sudan, by contrast, could benefit: When Ethiopia’s monsoon rains swell the Blue Nile, its confluence with the White Nile in Khartoum can contribute to severe flooding. Elhag contends the new dams could help regulate those flows, but she pointed to Sudan’s protracted war — which has caused one of the world’s gravest humanitarian crises — as the more immediate constraint on Khartoum’s position. Ethiopia denies fueling the war despite reports that it has backed the paramilitary Rapid Support Forces (RSF).

Cairo has consistently backed the Sudanese military and its government, which is fighting the RSF. Despite previously expressing support for construction of the dam, the Sudanese government has recently aligned itself with Cairo on the issue.

“Given Sudan’s current position and negotiating leverage, its interest right now leans more toward the engineering benefit than the economic benefit,” Elhag said.

An elusive diplomacy

A US-facilitated negotiating process in 2020 among Egypt, Ethiopia and Sudan remains an important reference point for Cairo’s preferred framework for coordinating the filling and operation of the GERD. The talks covered drought-management mechanisms, coordination, dispute resolution and information sharing, according to the US Treasury Department.

The process did not produce a final agreement signed by all three countries. The US Treasury said in February 2020 that Washington had facilitated the preparation of a proposed agreement based on work by the legal and technical teams of Egypt, Ethiopia and Sudan, with technical input from the World Bank. Ethiopia ultimately rejected the US-drafted proposal, objecting in particular to provisions it viewed as effectively determining the allocation of Nile waters.

During a bilateral meeting on the sidelines of the G7 summit in France on June 17, US President Donald Trump said that he and Egyptian President Abdel Fattah el-Sisi would be “discussing the Nile because the Nile is getting a little emptier than it should be,” according to an official US government transcript.

“A dam was built in Ethiopia, and it’s causing tremendous problems for Egypt, and I’m very aware. … We’ll see if we can settle it,” Trump said.

But Elhag noted that settling the dispute may not be simple, as the stakes extend beyond the two countries.

Kaldas sees room for cooperation grounded in mutual benefit. Egypt, he said, could help finance and expand Ethiopia’s power grid to ensure electricity “actually reaches the population” in exchange for joint management of the dams.

Compromise, for now, remains distant. Abdelatty maintains that protecting Egypt’s water rights is a matter of national survival. “We have the legal right to self-defense to preserve our water interests and security,” he told Al Arabiya.
