Monitoring Construction Progress of the Grand Ethiopian Renaissance Dam

Ethiopia

The Grand Ethiopian Renaissance Dam, formerly known as the Millennium Dam and sometimes referred to as Hidase Dam, is a project under construction on the Blue Nile River in the Benishangul-Gumuz region, about 40 km east of the border with Sudan. Once completed, this dam will be the largest hydroelectric power plant in Africa.  

From November 2013, through its GO Monitor Service, Airbus Defence and Space monitors this site on a monthly basis providing information on the dam construction progress, thanks to the photo-interpretation of a series of specially acquired Pléiades images.

The study of the Grand Renaissance Dam (Millennium Dam), made thanks to a series of Pléiades images, shows that earthworks for the foundations of the dam as well as the setting up of the first structures are in progress. When comparing this new image to a reference one, an increase of support activities is also observed: equipment and volume of materials, buildings, new structures for cement production directly on site.

The interpretation of this new Pléiades acquisition shows the continuation and progress of the site works: on each side we can observe the beginning of building foundations, as well as various facilities for the dam construction such as concrete stations.

Many areas are being developed for the storage of materials on each side of the river.

Dam foundations are in progress. An increase of the support activities is observed: important material movements, new earthworks areas, new buildings for workers could be noted.

March 2014

The Pleiades image acquired on March 20th shows that work is still on-going. Many excavated quarries supplying raw materials for the dam construction can be observed.
A second concrete plant is under construction on the left side of the river.

Various buildings designed for accommodation, workshops or equipment storage warehouses are visible.
Works related to a water reservoir construction is also observed about 8km south-east of the dam.
