The first Liechtenstein power station went into operation in 1927; its capacity is now 900 kW. Another station was constructed in 1947–49; it has an installed capacity of 9,600 kW. Total installed capacity in 1989 was 23,000 kW; production amounted to 150 million kWh in 1995. Since domestic production no longer meets local requirements, supplementary energy is imported from Switzerland, especially in winter. In 1995, 92.5% of Liechtenstein's energy requirement was imported from abroad. Consumption of electricity in 2001 was 313.5 million kWh. Imports of electricity in the same year totaled 232.8 million kWh.
