Energy supply – Energy Country Profile

Energy Supply


Slovenia has only few energy resources: sub-bituminous coal and lignite (315 Mt of lignite in 2016), and hydroelectricity (12 TWh).


As of 2016, the country's installed electricity capacity of 3.6 GW is distributed as follows: 38% hydro, 28 % coal, 19 % nuclear power, 8 % gas and 8% solar. Nuclear capacity is fully attributed to the Krsko plant (688 MW). Solar capacity amounts to 222 MW but only 36 MW were installed in the years 2012 to 2015. In 2016, a 545 MW steam power plant was commissioned which has been under trial since 2014. 

In 2016, power generation rose by 9% to 16.5 TWh, thanks to a 17% surge in hydropower and 14% growth in lignite-fired generation. Previously, power generation had increased by 1.8%/year between 2000 and 2014.






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

Imports of coal and lignite continued declining in 2015, however lignite production increased by 5.7 % in 2016 due to increased demand from the power sector. 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.
