A conflict that started in Khartoum is now testing Ethiopia's western border — and the dam that sits there
Sudan's war has not crossed into Ethiopia militarily — but it is creating real and growing pressure on Benishangul-Gumuz through refugee flows, cross-border armed group activity, and the destabilisation of communities that were already fragile. The GERD dam sitting in the same region elevates the strategic stakes considerably. The risk is not an RSF invasion of Ethiopia. It is a slow erosion of stability in a region that Ethiopia can least afford to neglect.
For most of its existence, Benishangul-Gumuz has attracted attention for two things: its rich natural resources (gold, fertile land, forests) and the fact that it is where Ethiopia chose to build the Grand Ethiopian Renaissance Dam — the largest hydroelectric project in Africa.
Since Sudan's civil war began in April 2023, hundreds of thousands of Sudanese have fled into neighbouring countries. Ethiopia has received a significant share — estimates suggest over 100,000 Sudanese refugees have entered Ethiopia, many crossing through the Benishangul-Gumuz border points of Metema and Kurmuk.
The humanitarian infrastructure in BGI was already stretched before the war. The influx has strained food supplies, health services, and shelter in border communities. The UN and international NGOs have scaled up presence in the region, but access to remote border areas remains difficult.
The RSF has advanced across much of Sudan's agricultural heartland, including areas in Gedaref state that sit close to the Ethiopian border. Gedaref is economically important — it is Sudan's breadbasket — and its partial destabilisation has sent additional displaced people toward Ethiopia. More concerning is that as RSF forces operate in areas increasingly close to the border, the risk of cross-border incidents — deliberate or accidental — rises.
There is no confirmed evidence that RSF forces have entered Ethiopian territory. However, several communities in BGI's Kamashi zone have reported armed incursions and cattle raiding by groups crossing from Sudan, which local authorities have struggled to distinguish from opportunistic crime versus organised spillover.
Benishangul-Gumuz was already one of Ethiopia's most conflict-affected regions before Sudan's war began. Starting in 2018, armed Gumuz groups carried out a series of attacks on Amhara and Shinasha settlers in the region, displacing tens of thousands and killing hundreds. The Ethiopian government deployed federal forces and eventually brought the situation under relative control — but underlying ethnic tensions remain unresolved.
The arrival of Sudanese refugees and cross-border armed groups into an already tense environment creates conditions for further instability. Armed groups from Sudan crossing for economic reasons can become entangled with local conflict dynamics, either as hired fighters or as pressure on already scarce resources.
The Grand Ethiopian Renaissance Dam (GERD) sits on the Blue Nile in Benishangul-Gumuz, approximately 15 kilometres from the Sudanese border. When complete, it will generate up to 6,450 megawatts of electricity — more than doubling Ethiopia's current power generation capacity. The dam represents Ethiopia's single largest infrastructure investment and is central to Abiy Ahmed's economic vision for the country.
Egypt and Sudan have contested the dam for years, arguing it threatens their Nile water share. With Sudan now in civil war, the dam's security calculus has shifted. The SAF government in Port Sudan is preoccupied; the RSF has shown no particular interest in the dam — but its proximity to active conflict zones raises questions about the security of the site and the workers stationed there.
Any threat to the GERD — physical, logistical, or to its workforce — would be a national crisis for Ethiopia. The Ethiopian government has maintained a heavy security presence around the dam, and there is no indication of any credible threat to the structure itself. But the broader destabilisation of BGI is a risk that Addis Ababa takes seriously.
The Ethiopian federal government has taken several steps to manage the border situation:
Ethiopia's position is delicate. It needs to manage the border without being drawn into the Sudan conflict on either side. The SAF has accused the UAE of arming the RSF — and the UAE is also one of Ethiopia's most important economic partners. Addis Ababa has opted for careful neutrality.
Most cross-border conflicts follow a straightforward pattern: fighting in one country, refugees fleeing, and occasional armed group activity near the border. The BGI situation has additional layers that elevate its importance:
