Energy production from renewable resources accounts for the vast majority of domestically produced electricity in Liechtenstein. Despite efforts to increase production, the limited space and infrastructure of the country prevents Liechtenstein from fully covering its domestic needs from renewables only. Liechtenstein has used hydroelectric power stations since the 1920s as its primary source of do. [pdf]
Energy in Liechtenstein describes energy production, consumption and import in Liechtenstein. Liechtenstein has no domestic sources of fossil fuels and relies on imports of gas and fuels. The country is also a net importer of electricity.
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). Hydroelectric power production accounted for roughly 18 - 19% of domestic needs.
Lawena Power Station is the oldest in the country, opened in 1927. The power station underwent reconstructions in 1946 and 1987. Today, it also includes a small museum on the history of electricity production in Liechtenstein. Samina Power Station, currently the largest of the domestic power stations, has been operational since December 1949.
Liechtenstein municipalities can obtain the Energy City label if they continuously ensure efficient energy use, increase investments for renewables, including solar energy, wind energy and hydropower, and promote environmentally compatible mobility. The certificate is awarded by the Energy City Sponsoring Association.
In 2010, total consumption of electricity in the Principality of Liechtenstein amounted to roughly 350,645 MWh. In 2015, total consumption of electricity in the Principality of Liechtenstein amounted to roughly 393.6 million kWh.

The power station has a capacity of 37.5 megawatts, sold directly to the state-owned Ivorian electricity utility company, Société de Gestion du Patrimoine du Secteur de l'Electricité (SOGEPE), for integration in the national electricity grid. The electricity is evacuated via a substation near the power station. The energy generated will power approximately 30,000 homes. In addition to supplying the country with 37.5 megawatts of clean energy, the power station will. [pdf]
