Itaipú Hydroelectric Factory

Man's hands seem not to have limits when it is time of channeling the energy of nature for his own benefit. Itaipú Factory, located in the border of Brazil and Paraguay is true evidence of that.

Built on Paraná River, in the frontier with Brazil and Paraguay, with installed power of 12,600 MW, Itaipú Hydroelectric Factory is responsible of generating 25% of the Electric energy used in Brazil and of 95% of the energy used in Paraguay.

Itaipú - "land that sings" in Guaraní Language- is the result of a treatment signed on 26th April, 1973 between Brazil and Paraguay establishing that the energy produced by the Hydroelectric Factory would be divided in even rates for both countries. The construction started in 1975 and ended in 1991 having 18 turbines in all which are capable of generating 93.4 millions of MW / h

Thanks to the imposing engineering work, Itaipú has become a great touristic attraction in Foz de Iguazú. Video displays and an interesting guide tour around its building will help the visitor find a beautiful panoramic view from the central vantage point to the lake formed by the dam. One can observe the diversion channel, the worker's wall paint and the worker's wood where each employee that has worked for the company for 15 years plants a tree.

Astonishing figures

The pace of construction of Itaipú was equivalent to the construction of a 20-storey building every 55 minutes.

With the total amount of concrete used to build Itaipú, 210 stadiums like "Maracaná" of Rio de Janeiro could be built.

The size got by the rock and digged soil is equivalent to more than twice the size of "Pan de Azúcar" in Rio de Janeiro.

The iron and steel used in the construction would be enough to build 380 times Eiffel Tower in Paris.

Itaipú drain can drain 62 million liters per seconds, 40 times the amount of Iguazú Falls.
