The Gilgel Gibe III Dam is a 250 m high roller-compacted concrete dam with an associated hydroelectric power plant on the Omo River in Ethiopia. It is located about 62 km (39 mi) west of Sodo in the South Ethiopia Regional State. Once fully commissioned, it will be the third largest hydroelectric plant in Africa with a power output of about 1,870 Megawatt (MW), thus more than doubling Ethiopia's total installed capacity from its 2007 level of 814 MW. The Gibe III dam is part of the Gibe cascade, a series of dams including the existing Gibe I dam (184 MW) and Gibe II power station (420 MW) as well as the planned Gibe IV (1,472 MW) and Gibe V (560 MW) dams. The existing dams are owned and operated by the state-owned Ethiopian Electric Power, which is also the client for the Gibe III Dam.
The US$1.8 billion project began in 2006, electricity generation started in October 2015. The remaining generators were operational by 2016. The project has experienced serious delays; in May 2012, full commissioning had been scheduled for June 2013. The dam was inaugurated by Prime Minister Hailemariam Desalegn on 17 December 2016.
