Evaluation of the remaining hydro potential in Italy

A methodology is described to evaluate the residual hydropower potential in Italy, taking into account the current demands on water resources (irrigation, drinking water, existing hydropower). The model applied uses a numerical technique coupled with a GIS, the hydrological and physiographic characteristics of nearly 1500 interconnected sub-basins, and rainfall maps. Maps of water resources availability and the related maximum hydropower potential have been produced and are found to be quite helpful tools to support power authorities, decision makers and other stakeholders in creating energy masterplans, and in implementing small hydro plants.
