  • By 2030, Slovenia aims to cap primary energy demand at 6.4 Mtoe and to cover 27% of final energy consumption with renewables.
  • HSE, a state-owned company, represents 56% of the power generation.
  • Geoplin dominates the gas market (76% of the wholesale market and 45% of the retail market).
  • National company Petrol is the largest fuel retailer.
  • Two-thirds of the power mix is CO2-free.
  • Residential electricity and gas prices are 25% lower than the EU average.
  • Industrial gas prices have doubled between 2020 and 2022.
  • Total energy consumption recovered in 2021 after declining since 2017.
  • The energy intensity is decreasing rapidly.
  • Slovenia is developing many electricity and gas interconnection projects.
  • With the exception of a 420 MW hydropower project, the development of large capacities remains uncertain as many wind projects were abandoned.

  • Institutions & Energy Policy

    The Energy Directorate of the Ministry of Infrastructure is in charge of defining the energy policy objectives.

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

  • Energy Companies


    Petrol is the national oil company (32.3% state-owned). In 2021, Petrol sold 3.1 Mt of oil products, 45% of which in Slovenia.

  • Energy Supply


    As the country's only refinery ceased operating in 1998, Slovenia imports all its oil products (4 Mt in 2020). Italy is its largest supplier (31% in 2020), followed, Austria (14%) and Russia (13%). Preliminary data for 2021 anticipate a decrease in oil products import for 2021 (-4%) as Greece would move to the number one supplier.

  • Energy Prices


    Residential gas prices that had been increasing slowly since 2017 (+1.1%/year until 2021) soared in 2022 (+26%). In industry, gas prices have more than doubled since 2020 (22% in 2021 and 60% in 2022), after a low level in 2020.

  • Energy Consumption

    Per capita consumption is 3.1 toe (less than 2% higher than the EU average in 2021). Electricity consumption per capita exceeds 6 400 kWh (12% above the EU average).


  • Issues & Prospects


    According to Plinovodi's latest forecasts, gas consumption should increase from 9.6 TWh in 2020 to 12.8 TWh in 2031 (2.7%/year). A large part of the expected rise in gas consumption is attributed to the commissioning of the TE-TOL CCGT unit in 2023, which is expected to consume 1.95 TWh/year.
