Ok you may not get this on your first try but u will. The first
generator will be on the first building on the right kill the guard
that guards the building quickly or else he will hit the alarm. Pick
the lock of the door and take out a shotgun kill them then destroy
that generator. Then there are 2 other enemy's the one at the big gate
is the last one you want to kill in that room place take him out and
there is a small hut with the next generator. Then find the next door
go to the left and shoot the one guy walking back and forth then go
into the second hut or the hut on the right and there is a generator.
Kill all the enemies around that whole room then finding the last
generator is easy. Then find the latter and go up and listen to the
girl.
