is the world's biggest hydroelectric power station,
and is located along the border River Parana, between
Brazil and Paraguay. It is only 14km north of Foz
do Iguassu downtown. It is an amazing construction,
imagining one sole dam that has the capacity to generate
12.600 Mega Watt per month and provides 95% of the
consumption of energy in Paraguay (5milj. inhab.)
and 24% of the Brazilian (170milj. inhab.) demand
of energy. During the year 2000 a world record was
hold, an annual production of 93,428GWh.
height of the main dam is 196 meters, which is equivalent
to the height of a 65 storey building. The total volume
of concrete used in the construction of Itaipu would
be sufficient to build 210 football stadiums like
the Maracanã, in Rio de Janeiro. The iron and steel
employed would permit building 380 Eiffel Towers.
The maximum flow over the Itaipu spillway (62.2 thousand
cubic meters per second) corresponds to 40 times the
average flow over the Iguassu Falls. The flow through
two Itaipu turbines (700 cubic meters of water per
second each), corresponds to the total average flow
of the Iguaçu Falls (1500 cubic meters per second).
The volume of earth and rock excavations at Itaipu
is 8.5 times greater than that of the Euro tunnel
(that links France and England under the English Channel)
and the volume of concrete is 15 times greater. The
area of the reservoir is 1,350km2.
tour takes about 1,5hours. Upon arrival to the Itaipu
Plant, you will go with a local bus and first watch
a short film telling about the history of the dam,
one of the "seven wonders of the world". Then you
will experience a show of lights.
