Itaipu Dam

We're now on a tour of the Itaipu Dam - the world's largest hydro-electric power plant.


Here's the spillway from the Paraguay side of the dam.


There are 20 turbines - 10 each owned by Paraguay and Brazil. They are under these white tubes - Paraguay's on the left (1-9B), Brazil's on the right (10-18B)


Paraguay uses 1.5 turbines for essentially all the country's power. Brazil uses its 10 and buys Paraguay's surplus power for about a quarter of Brazil's power.
