Cimarron Hydroelectric Power Project a hydroelectric power plant in El Salvador, that was to start construction in 2010. The plant would have been be located in the upper basin of the Lempa River, upstream of the Cerrón Grande Hydroelectric Dam. The proposed location of the dam was between the towns of Agua Caliente, Chalatenango on the left shore and Metapán, Santa Ana, on the right shore. A tunnel would divert water from the Lempa River to a powerhouse and substation to be built near Agua Caliente.〔(【引用サイトリンク】url=http://www.cel.gob.sv/?categoria=29 )〕 With an estimated capacity of 261 megawatts, the project would have increased El Salvador's total generation capacity by almost 25%. ==Main features== The dam would be built at 695 meters above sea level and would have had a height of 165 m and a length of 660 m. The dam reservoir would have covered an area of 15.3 km² and a capacity of 592 million m³.〔 The main stream tunnel was to conduct a total flow of 83.1 cubic meters per second from the dam to the plant; Four vertical axis Pelton turbines, with an installed capacity of 261 megawatt, would generate a yearly average of 686.7GWh.〔 A 235 kV power line will connect the power plant to the national grid. Environmental impact studies, initiated in 2005 and concluded in 2007, identified mitigation measures.〔 One hundred and fifty families would have been relocated from their current homes. Waters of the Lempa River would have been diverted towards the Metayate River by way of a 1,200 meters discharge channel. The natural flow of the Lempa River would therefore be altered for a total length of 30 kilometers.〔 In El Salvador, the evolution of current oil prices made the Cimarrón Project more attractive than fossil thermal plants, which could provide comparable output. The estimated rate of return (ERR) of the Cimarrón is 12.23%. 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「Cimarron Hydroelectric Power Project」の詳細全文を読む スポンサード リンク
