Browse the tabs below for a detailed table of contents, the list of graphs and tables, and details on the data files.


  • Slovenia introduced more ambitious targets on renewables, energy efficiency, and GHG emissions reduction for 2030 in its revised NECP.
  • The country aims to phase out coal by 2033.
  • HSE, a state-owned company, represents half of the power generation.
  • Geoplin dominates the gas market (76% of the wholesale market and 47% of the retail market).
  • National company Petrol is the largest fuel retailer.
  • 73% of the power mix is CO2-free (2022).
  • Electricity and gas prices increased significantly in 2022 and 2023, despite support measures.
  • Total energy consumption declined slightly in 2022.
  • Slovenia is developing many electricity and gas interconnection projects.
  • A referendum will be held in 2024 on the construction of a second nuclear reactor of up to 2.4 GW at Krško.

  • Institutions & Energy Policy

    The Energy Directorate of the Ministry of the Environment, Climate, and Energy is in charge of defining the energy policy objectives and regulating public utilities.

    The Ministry of Infrastructure oversees transport and energy infrastructure and ensures energy supply is reliable.

    The Energy Agency (Agencija za energijo) is in charge of regulating the energy markets.

  • Energy Supply


    Slovenia imports gas from Russia, directly or through Austria. It also imported gas from Algeria, through Italy, from 1992 to 2012. In 2022, Slovenia imported 0.8 bcm, of which 48% came from Russia, 28% from Austria (mainly Russian gas), and 10% from Italy.

  • Energy Prices


    Gas prices, which had remained rather stable between 2017 and 2021, soared in 2022. As of July 2022, Slovenia introduced measures to cushion the rise in gas prices, including a lower excise duty and VAT on gas until 31 May 2023 for all consumers and a maximum retail gas price for households and small businesses until the end of 2023 (extended until the end of April 2024 for households).

  • Energy Consumption

    Per capita consumption is 3.1 toe (6% higher than the EU average in 2022). Electricity consumption per capita exceeds 6 200 kWh (13% above the EU average).


  • Issues & Prospects


    According to ELES's 2023-2032 development plan, Slovenia's electricity demand in the transport network could reach 15-16 TWh/year in 2032.
