 : NortyNort, thanks, that's very kind of you. by the way, have a look at https://de.wikipedia.org/wiki/Liste_von_Wasserkraftwerken_in_Portugal. this article contains a map with most of the HPPs in Portugal, that I'm aware of (a few minor ones are missing, also Baixo Sabor, which is currently under construction) and a table with the properties of dams, reservoirs and HPPs. if something like this is of interest for the en.wiki, i'll copy it and adapt it.
