Salini completes record-breaking dam
Ethiopia has inaugurated a record-breaking dam that has been built by Salini Impregilo.
Gibe III is the first dam in Ethiopia to be built using roller-compacted concrete (RCC). It has a crest length of 630m and a height of 250m, which is said to be the tallest of its kind in the world. The volume of concrete used to build the dam totalled 6.2 million cubic metres and the reservoir holds 15 billion cubic metres, equal to half the volume of Ethiopia’ largest lake.
The Gibe III hydroelectric project has an installed capacity of 1,870MW - the same amount produced by two nuclear power plants - and will almost double the eastern African country’s electricity production. It will generate up to 6,500GWh of electricity a year, increasing the country’s production capacity by at least 80%.
The dam – which stands on the Omo River 450km southwest of the capital Addis Ababa - is the latest in a series being built by the country to harness its vast water supply.
