-Welcome to James Bay
in the heart of the Taiga, 
home to the Crees
for more than 4,000 years. 
This is where more than half
of Quebec's electricity
is generated.
As you can see, nature and water
dominate the scene.
Many species live up here,
but the most noticeable
are the black flies. 
Admire the landscape
all around you.
Look, there's lichen
and underfoot.
Let's tour the Robert Bourassa
generating facility. 
First the dam.
Welcome to Hydro Québec.
Do you see the huge reservoir?
It's almost three times
the size of Lac St-Jean. 
With this water, we generate
the greenest power in the world.
If you haven't already,
 you should turn around 
and see how high
the top of the dam is.
I hope you're not afraid
of heights. 
Now, we're at the foot
of the spillway.
It's known
as the giant staircase 
because of it's ten huge steps,
each 10 meters high.
But the birds-eye-view
is the best. 
Take a look.
Each step is the size
of two football fields.
This massive red door 
is the entrance
to the generating station,
140 meters underground,
which was dug out
of the bed of rock. 
Impressive, right?
It may seem nice and quiet
in the generating station,
but this is where
all the magic happens, 
right under your feet.
Water activates the turbine 
which spins the generator
to create an electric current. 
Each generating unit
can produce enough power 
for a town about the size
of Drummondville. 
Here are some people at work.
They're removing a part
that weighs nearly 4 tons 
for maintenance
to keep the generating units
working at their best.

The energy generated inside 
now enters
the transmission system.
Notice the transformers. 
They step up the voltage
to 735 kV.
So the electricity
can travel long distances.
Take a closer look at the
transmission lines and towers.
These lines carry electricity
from Radisson to Montreal 
in less than the blink
of an eye.
Thanks to the extraordinary
structures built at James Bay,
we produce clean,
renewable energy:
Hydropower!
Something generations to come
will continue to benefit from.
