Hydropower systems in Italy at the end of 2014 amounted to 3,432 with a total installed capacity of 18,418 MW. Between 2013 and 2014, the number of systems increased by 5.6%, while the overall increase in terms of installed capacity was only 0.3%. The incidence of the hydroelectric installed capacity compared to the Italian renewable installed base remained almost unchanged compared to 2013, increasing from 36.6% in 2013 to 36.4% in 2014. 
In recent years, therefore, hydropower has not changed significantly, since many small systems have come into operation. For the future, it is expected that especially small and mini hydropower systems will be installed, as in the last few years. Despite the limited growth of hydropower, in 2014 the installed capacity of hydropower accounted for 36.4% of the entire installed base of renewable systems.
At the regional level, 80.2% of hydropower systems are installed in northern Italy. In particular, in Piedmont (709 systems), Trentino Alto Adige (703) and Lombardy (487) there are 55% of the systems in Italy.
