Gilgel Gibe River is a tributary of the Gibe River in southwest Ethiopia. It flows in an arc through the south of the Jimma Zone, defining part of the Zone's boundary with that of the Southern Nations, Nationalities, and Peoples' Region west of the Omo River as it turns north. It then joins the Gibe River less than ten miles from its own confluence with the Omo. ==Hydroelectric potential== Plans to develop the hydroelectric potential of the Gilgel Gibe river were first announced in the 1980s. Construction of the Gilgel Gibe I Power Station started in 1986 and was completed in 2004, after being interrupted in the early 1990s. The plant includes a reservoir of about 850 cubic meters created by a dam about 40 meters high. The Gilgel Gibe river flows are therefore returned to the natural bed after having transformed the energy of the water into electricity through a powerplant equipped with three Francis turbines. The resettlement program required moving about 3,000 people to new areas including the people living under or near the power line connecting the power plant to Addis Ababa.〔(【引用サイトリンク】title=Gilgel Gibe Resettlement Project in Ethiopia ) 〕 Employing 307 expatriates from 32 countries and 4,015 local people, the plant was completed at a cost of about two billion birr and became Ethiopia's largest power plant, with a capacity of 184 megawatts.〔("New Hydroelectric Power Plant in Gilgel-Gibe Inaugurated by Prime Minister Meles Zenawi" ) (accessed 22 April 2006)〕 The second phase of the development of the Gibe-Omo hydropower potential started with the Gilgel Gibe II Power Station. The flows, regulated by the Gilgel Gibe I Dam, will be conveyed through a 26 km long hydraulic tunnel, the longest in Africa, to the Omo river about 2 kilometers downstream of the Gibe I. The plant will produce about 420 MW without requiring resettlement. This second phase was 97.5% complete in August 2009 and is scheduled for commissioning on September 2009 onwards.〔("New Hydroelectric Power Plant on Gilgel Gibe" ) (All Africa), subscription required; accessed 21 July 2006〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gilgel Gibe River」の詳細全文を読む スポンサード リンク
