Koysha Hydroelectric Project

Koysha Hydroelectric Project 2,160MW

Contract signed: 2016
Client: Ethiopian Electric Power (EEP)
Value: 2.525 miliardi di euro

 

The ambitious project, designed to exploit the water power of the Omo river (which has already spawned Gibe I, Gibe II and Gibe III), is today joined by a new hydroelectric plant of large dimensions that will have a huge impact on the development of Ethiopia in the coming years: the Koysha Hydroelectric Project.

The contract for the creation of the plant (in terms of Engineering, Procurement and Construction) was signed on 28 March 2016 by Ethiopian Electric Power, which is financing the project, and by Salini Impregilo, appointed to build the plant.
Five years of work are envisaged for a megaproject worth two and a half billion euro, including the construction of a 175 metre-high dam in Roller Compacted Concrete with a holding capacity of 6,000 million cubic metres.

The plant also comprises an outdoor electric power station hosting 8 Francis turbines which will guarantee an installed power of 2,160 MW and an annual production capacity of 6,460 GWh.

The project, located in the south west of the Country, will be the fourth plant in a waterfall dam system on the Omo river. Indeed, the Gibe I and Gibe II plants have already been completed upstream, while Gibe III is 98% completed.
The Koysha hydroelectric plant, together with that of Gibe III and with the Grand Ethiopian Renaissance Dam on the Blue Nile (GERD), will enable Ethiopia to become a leading player in the production of energy in the African market.
