The white area near the top of this image is the city of Foz do Iguaçu, in the Brazilian state of Paraná, by the triple border between Brazil, Paraguay and Argentina. Visible to the north of the city is the reservoir created by the Itaipu Dam, a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay.
The dam is the largest operating hydroelectric facility in terms of annual generating capacity, generating 94.7 TWh in 2008 and 91.6 TWh in 2009. In 2008 the plant generated a record 94.68 TWh, supplying 90% of the electricity consumed by Paraguay and 19% of that consumed by Brazil.
Visible to the west is the Rio Yguazú Lake, while to the east, the San Antonio River, a tributary of the Iguazu River, can be seen. The San Antonio River forms the border between Misiones Province in Argentina and Paraná State in Brazil. South of the San Antonio’s source near Barracão, the international border continues south along the Pepiri-Guazu River, which forms the border between Misiones Province and Santa Catarina State.
