Situated on the Parana River, the Itaipu dam straddles the border between Brazil and Paraguay.
Here, Sustainable Energy takes a look at this icon of hydropower, assessing the impact it has on the countries it supplies energy to.
In its first year of operation Itaipu produced 276,529 megawatt hours of power. In 2016, that figure hit 103,098,366 megawatt hours, a world record for annual generation.
In terms of scale, Itaipu is vast. The dam's length – when taking into account the Hernandarias dike – is 7,919 meters, while its maximum height hits 196 meters.
A staggering 12.3 million cubic meters of concrete were used in its construction, with the steel and iron used enough to build 380 Eiffel Towers.
"Our generating units are 700 megawatts each," Juliano Portela, an engineer at Itaipu Binacional, told CNBC's Sustainable Energy. "We have 20 generating units installed, which comprises a total of 14,000 megawatts," he added.
