The Grand Ethiopian Renaissance Dam: introduction and benefits

The Grand Ethiopian Renaissance Dam

The Grand Ethiopian Renaissance Dam (GERD): the biggest hydroelectric project in Africa since its launch in 2011, and the most controversial one as well (Verhoeven, 2021). The GERD is not the only dam on the Nile river, as shown by Figure 1. However, it is the most controversial. Why is that? This post will consider the politics of the GERD, taking a particular focus on the benefits of the dam for Ethiopia, but also the other Nile riparian countries.

Figure 1: The major dams in the Eastern Nile River Basin

The Grand Ethiopian Renaissance Dam, located 45km to the east of the border with Sudan and 750 km northwest of the Ethiopian capital of Addis Ababa, is a hydroelectric dam located on the Blue Nile. It is set to become the largest hydropower plant in Africa (Burck, 2021). This huge project was funded internally, including through selling bonds to the Ethiopian diaspora (Xinhua, 2018).

The GERD started being operational on the 20th of February 2022 (Getachew, 2022) With a capacity of more than 6,000 megawatts, the dam will enable Ethiopia to become a major power exporter, as well as provide electricity to millions of citizens and help lift Ethiopians out of poverty. In addition to this, the country will have the opportunity to sell its hydropower surplus to its neighbours. This will also help Egypt, who primarily uses fossil fuels, as they will have access to a less expensive and less polluting energy supply (Gebreluel, 2014). During the launch of the project in 2011, the Ethiopian Prime Minister Zenawi clearly emphasised that the benefits accrued from the GERD were not restricted to his country, and that the downstream states would stand to profit from the dam as well (Tawfik, 2016). The dam also benefits Sudan and Egypt by "removing silt and sedimentation, by regulating water flow and by conserving water in Ethiopian highlands" (Tesfa, 2013). Concerning sedimentation, the GERD will be able to "capture 90% of the sediment", therefore protecting irrigation canals from being damaged as a result of sedimentation. The regulation of the water flow will help Sudan and Egypt manage their reservoirs better, and eliminate the risk of the High Aswan Dam (HAD dam further downstream in Egypt) overtopping, as well as reducing the annual evaporation losses of the HAD (Embassy of Ethiopia, 2021).

Ethiopia considers the construction of the dam as a fundamental right (Bearak and Raghavan, 2022). The GERD is also viewed as a symbol of national pride and unity, as seen by Ethiopians all around the world celebrating the progress in the dam's construction (Meseret, 2020). It will allow Ethiopia to contest Egypt's historical hegemony in the region, establishing Ethiopia as a regional power in East Africa. While Ethiopia has continuously reaffirmed that the GERD won't have any major impact on the Nile's waterflow downstream, Egypt fears for its water security (Mukum Mbaku, 2020). 

In the next post, I will continue to look at the Grand Ethiopian Renaissance Dam. After considering the benefits of the dam, I will explore the GERD as a potential source of conflict.

Hello and welcome to my blog! Over the next few weeks, I am going to research and write blog posts about the dynamics of water politics in Africa.  Before I start, I must admit that I do not know a lot about water and development in the continent of Africa. This lack of knowledge on such an important issue, and of Africa in general, has drawn me to choose this module. Africa tends to be presented to Western audiences by the media as a huge single entity, as 'one country', a point highlighted by Binyavanga Wainana in his article ' How to write about Africa '. This is something I have noticed in my everyday life. A non negligeable amount of people will talk about Africa without precising which country they are referring to, if any, something they wouldn't do for other continents. Inhabitants of Western countries sometimes see issues in a certain African country and generalise these same issues to be present everywhere on the continent. This is the case of water in Afr

The Grand Ethiopian Renaissance Dam: conflicts

In the second post, I briefly explained Egypt’s reliance on the Nile, as well as some of the worries concerning its historical right to the Nile being contested. In this post, I will delve deeper into these worries in the context of the GERD and look at the potential conflicts that may arise.  I will also look at how Egypt has responded to the looming threat of a reduction in its share of the Nile’s water because of the GERD. Egypt and Sudan's joint military drill  While there has been no direct armed conflict between Egypt and Ethiopia over the GERD, Egypt has shown it would be prepared if a direct confrontation ever took place. In April 2021, Egypt and Sudan conducted a joint aerial military exercise, whilst in the middle of tensions with Ethiopia over the dam ( Sabry, 2021 ).  In addition, Egypt has, on multiple occasions, objected to Ethiopia’s unilateral filling of the GERD without a deal with them and Sudan, going as far as writing an official complaint to the UN Security Cou
