Gilgel Gibe I - Dam and Tunnel, Ethiopia

One third more energy compared to previous production. This was achieved by Gilgel Gibe I facility, the first of three projects comprising the extensive hydropower complex located between the Gilgel Gibe and Omo rivers, an affluent in Ethiopia.

The project aligns with the country's hydroelectric potential development plans dating back to the 1960s, and builds on initial studies and attempts initiated by local and North Korean enterprises since the late 1980s.

Completed in 2004, Gilgel Gibe I consists of a rockfill dam and a 9 km diversion tunnel, housing a cavern power station with three Francis turbines and a total installed capacity of 183 MW. The power station has increased Ethiopia's electricity production by one third.
