it's the most powerful hydroelectric
plant in the world and one of the
largest dams on earth
[Music]
it's a really amazing place it's
gigantic how big
is it exactly the dam measures nearly
7.5 kilometers
its total height is 225 meters
225 meters above sea level exactly
how high is the waterfall it falls 120
meters
water hits each turbine producing 700
megawatts
so each turbine is roughly the same
power as a nuclear reactor
has a capacity of 14 000 megawatts
so compare that with a nuclear plant
producing 1000 megawatts
that's the equivalent of 14 nuclear
power plants
it's really amazing this monster
supplies almost
90 percent of the electricity consumed
in paraguay and 50
of its brazilian neighbors electrical
power thanks to an architecture and
location
that was thoroughly studied by engineers
what kind of dam is the boo dam
it's a gravity dam built on very solid
basaltic rock
the same as can be found along the river
it was built on the piranha river canyon
was chosen by engineers because this was
where it was possible
to extract the most electrical energy
from the flow of water into the power
plant
they have achieved the best possible
rate of productivity
so it's a combination of water flow and
geology that makes this the
optimum location yes
completed in 1991 the structure forms a
gigantic
1 350 square kilometer reservoir
but the sacrifice is demanded by this
incredible dam are commensurate with its
height
to create the lake the authorities had
to displace 10 000 families
and drown the rainforest beneath 100
metres of water
the first dam construction site with an
animal rescue plan
the site is now classified as a unesco
biosphere reserve
plant and dam stand on exceptionally
strong foundations capable of holding
back 29 million cubic meters of water
