巴西的萨尔托卡希亚斯水电工程是一座费用为 1 0亿美元的大型水电工程 ,工期为 4a多。相对于大型水电工程工期而言 ,该工程工期非常短 ,这是因为采用了先进的设计及施工技术。伊瓜苏河良好的地形和地理条件使该工程成本低廉 ,该工程全部并网发电后 ,将为巴西提供大量廉价电能 ,使巴西未来几十年内用电状况得到改善。 The Salto Cahias Hydropower Project in Brazil is a large hydropower project costing $ 1 billion and has a duration of more than 4a. Compared to the duration of a large hydropower project, the construction period is very short because of the advanced design and construction techniques. The good geographical and geographical conditions of the Iguazu River make the project cost-effective. When all the grid-connected electricity is generated, the project will provide Brazil with a large amount of cheap electricity and will improve Brazil’s electricity consumption in the next few decades.
