Samina Power Station, currently the largest of the domestic power stations, has been operational since December 1949. In 2011-2015, it underwent a reconstruction that converted it into a pumped-storage hydroelectric power station. In recent decades, renewable energy efforts in Liechtenstein have also branched out into solar energy production.
Liechtenstein has used hydroelectric power stations since the 1920s as its primary source of domestic energy production. By 2018, the country had 12 hydroelectric power stations in operation (4 conventional/pumped-storage and 8 fresh water power stations).
