Good night @xpilar, you can see that it is a great construction, which at first glance does not look like a hydroelectric plant, has similarity to Roman constructions, is very nice, and I imagine they have no operational problems.
I would like my country (Venezuela) to have one like this and to stop suffering from the problems of electrical rationing that we experience every day.
