Living in Boquete Panama I have been exposed to talk about La Fortuna power plant. I have driven over two dams called La Fortuna, one in route to Almirante the other near Gulaca but I have never seen turbines or spillways or electric lines leading away form those bridges. Being a former Arizonan I am accustomed to the massive infrastructure at Boulder Dam on the Arizona Nevada border. La Fortuna does not appear to have any of that.
This time as I was driving from Almirante I stopped at the dam and visitors center and discovered the difference. The dam does hold a reservoir but unlike hydroelectric plants I have seen before the generators are not in the dam but in an underground tunnel down hill from the dam.
I make no claim to know anything about this technology and whether it is better, worse or for a different environment than some of raging rivers of North America. I did take a few photos of the reservoir and a model of the total infrastructure in the visitors center.
I f any reader can shed light on this design please do.
