Highlights

  • Slovenia introduced more ambitious targets on renewables, energy efficiency, and GHG emissions reduction for 2030 in its revised NECP (2024).
  • The country aims to phase out lignite by 2033 at the latest.
  • HSE and Gen Energija represent nearly 60% of the power generation (2025).
  • Geoplin dominates the gas market (80% of the wholesale market and 460% of the retail market).
  • National company Petrol is the largest fuel retailer.
  • The share of CO2-free sources in the power mix has increased by 15 points since 2010, reaching 78% in 2025.
  • Final energy consumption is slightly decreasing.
  • Electricity and gas prices increased significantly in 2022 and 2023, despite support measures.
  • Slovenia is developing many electricity and gas interconnection projects.
  • A second nuclear reactor of up to 2.4 GW is planned at Krško and SMRs are under consideration.

  • Energy & Climate Policy Framework

    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 Companies

    Electricity:

    HSE, Holding Slovenske Elektrarne (100% state-owned), used to be the largest electricity producer, until the transfer to the State of its 942 MW Šoštanj lignite-fired power plant in January 2025. Through its stakes in various companies, HSE operates 970 MW (19% of the total capacity at end-2025), consisting of 912 MW of hydro and 58 MW of thermal. In 2025, HSE generated 3.3 TWh, i.e.

  • Energy Supply & Demand

    Oil:

    Slovenia doesn't produce crude oil. As the country's only refinery ceased operating in 1998, the country imports all its oil products (4.4 Mt in 2025, 4.5 Mt/year on average since 2016). Most of product imports came from Saudi Arabia (27% in 2025), Italy (18%), and Greece (8%).

  • Energy Use and Price by Sector

    Energy Prices in Residential:

    Household electricity prices in Slovenia are lower than the EU average (30% lower in 2024) and taxes account for 21% of residential prices (2025).

  • Issues & Prospects

    Gas:

    According to Plinovodi's latest forecasts, gas consumption should increase by around 2.2%/year between 2026 and 2035, slightly declining in the residential, services, and industrial sectors but rising by nearly 10%/year in the power and CHP sector.
