The Grand Ethiopian Renaissance Dam (GERD) - It is a 6,450 MW hydropower project nearing completion on the Blue Nile in Ethiopia, located about 30 km upstream of the border with Sudan. It will be the largest hydropower project in Africa. Owned and operated by the Ethiopian Electric Power company, the 145-m-tall roller-compacted concrete gravity dam will flood 1,874 km2 at a normal pool elevation of 640 m, and will have a tributary catchment of 172,250 km2. With a volume of 74 km3 (of which 14.8 km3 is dead storage), the reservoir can hold about 1.6 years’ worth of average flow of the Blue Nile.
