The Itaipu Dam (Guarani: Presa Itaipu, Portuguese: Barragem de Itaipu, Spanish: Represa de Itaipú; Portuguese pronunciation: [itɐjˈpu], locally: [ita.iˈpu], Spanish pronunciation: [itaiˈpu]) is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay. The construction of the dam was first contested by Argentina, but the negotiations and resolution of the dispute ended up setting the basis for Argentine-Brazilian integration later on.
The name "Itaipu" was taken from an isle that existed near the construction site. In the Guarani language, Itaipu means "the sounding stone". Itaipu is the hydroelectric plant that produces more energy in the world, setting a new world record in 2016, 103,098,366 megawatt hour (MWh); and had surpassed the Three Gorges Dam plant in 2016 and 2015 in energy production. Completed in 1984, it is a binational undertaking run by Brazil and Paraguay at the border between the two countries, 15 km (9.3 mi) north of the Friendship Bridge. The project ranges from Foz do Iguaçu, in Brazil, and Ciudad del Este in Paraguay, in the south to Guaíra and Salto del Guairá in the north. The installed generation capacity of the plant is 14 GW, with 20 generating units providing 700 MW each with a hydraulic design head of 118 metres (387 ft). In 2016 the plant generated a new world record. In 2016, the plant employed 3038 workers.
