The second phase of the development of the Gibe-Omo hydropower potential started with the Gilgel Gibe II Power Station on the Omo River. The flows of the Gilgel Gibe River, regulated by the Gilgel Gibe I Dam, are conveyed through a 26 km long hydraulic tunnel through the Fofa mountains to the Omo River in the neighboring river valley downstream of the Gilgel Gibe I. The plant, that produces about 420 MW did not require resettlements. This second phase was 97.5% complete in August 2009 and was scheduled for commissioning on September 2009 onwards.
