Energy supply – Energy Country Profile

Energy Supply


Slovenia has only few energy resources: sub-bituminous coal and lignite (315 Mt of lignite in 2019), and hydroelectricity (12 TWh). The country`s independence rate stood at 52% in 2019.


As of 2019, the country's installed electricity capacity of 3.8 GW is distributed as follows: 35% hydro, 27% coal,  18% nuclear, 12% gas and 7% solar (end of 2019). The nuclear capacity includes the whole capacity of Krško (688 MW), which is located in Slovenia and is jointly owned by Slovenia and Croatia. The reactor has been allowed to operate for 60 years until 2043. Solar capacity reached 264 MW at the end of 2019. Only 40 MW were installed since then due to the end of feed-in tariffs. 

Power generation has been declining slightly since 2016 to 16 TWh in 2019 (-1.4% in 2019). Power generation had increased by 1.8%/year between 2000 and 2014. Nuclear is the main source of power (36% in 2019), followed by hydro which
varies considerably depending on the year (29% in 2019), and 33% for thermal (mainly lignite with 28%).




Slovenia only has one refinery in Lendava (13.500 b/d), however, besides a temporary operational phase in 2010, the refinery ceased operations in 1998. Slovenia therefore imports most of its refined oil products from Italy, the United States and Russia. 


Slovenia's gas import comes from Russia through Hungary and Austria and since 1992 from Algeria through Italy. To reinforce the interconnection with the Baumgarten hub in Austria Geoplin Plinovodi commissioned a new gas pipeline in 2011 between Kidričevo and Ceršak at the Austrian border.

Coal & Lignite

The Velenje lignite mine is still in operation as it has a contract to supply the Sostanj power plant until 2054. The Trbovlje coal mine ceased operations in 2013.
