Electricity price in Slovenia today
The spot price of electricity hour by hour in SI (SI), Friday, 23 October 2026.
Slovenia makes most of its electricity from three main sources that could hardly be more different: a nuclear plant it shares with Croatia, hydropower from Alpine rivers, and a lignite-fired plant in the Šalek valley. Gas plays only a small part at home, but gas-heavy Italy is right next door, and the two markets are coupled.
The country forms a single bidding zone, and this page shows its day-ahead price hour by hour. With about two million people and a grid that carries large flows between Central Europe and Italy, Slovenia's price is shaped as much by its neighbours as by its own power stations.
Today electricity costs 21.5 c/kWh in SI (SI) on average.

How the electricity price works in Slovenia
One zone, the BSP exchange and price caps in the crisis
Day-ahead trading runs through BSP, the energy exchange in Ljubljana, which is part of the European market coupling, so the hourly price is calculated together with the rest of the continent. ELES runs the transmission grid, and the Energy Agency (Agencija za energijo) regulates network charges and supervises the market. Households choose their supplier freely. When wholesale prices exploded in 2022, the government used decrees to set maximum retail prices for households and small businesses, and it extended such measures more than once.
Omrežnina, contributions and excise
The bill has three layers. First the energy from the supplier. Then the network charge (omrežnina), which since a reform in 2024 depends both on the agreed connection power and on five time blocks, with the dearest hours on winter working days. Finally the levies: a contribution that funds support for renewables and high-efficiency cogeneration, a contribution for energy efficiency, excise duty and VAT on top. Because the time blocks also price capacity, how evenly a household spreads its use now matters for the network part.
Rivers, refuelling and Italy
Hydropower output follows rain and snowmelt along the Sava, Drava and Soča, so a wet spring and a dry late summer can feel very different. Krško runs around the clock except during planned refuelling outages, when Slovenia leans more on imports and coal. The cost of running the Šoštanj plant rises with the price of EU emission allowances. And because a lot of power flows through Slovenia towards Italy, Italian demand and gas prices are felt here whenever the lines across the border have room.
Nuclear, hydro and lignite, with solar catching up
Krško, a single pressurised-water reactor on the Sava near the Croatian border, delivers the largest share. Statistics count its whole output as Slovenian, although half of it belongs to Croatia. Hydropower comes from chains of plants on the Drava, Sava and Soča. The Šoštanj thermal plant burns lignite from the neighbouring Velenje mine. Solar panels on roofs have spread quickly in recent years, while wind power is almost absent.
Between the Alps, the Adriatic and the Pannonian plain
Slovenia borders four very different power systems. Austria is dominated by hydropower and has a surplus in summer, when the rivers run high; Italy depends on gas and typically pays more; Croatia shares Krško and has hydro of its own along the Adriatic; Hungary relies on its Paks nuclear plant and fast-growing solar. Sitting in the middle, Slovenia often acts as a corridor, which is why its price tends to move with whichever neighbour the grid binds it to in a given hour.
Slovenia compared with its neighbours
In 2024, nuclear made 35%, hydro made 30% and coal, lignite and peat made 21% of the electricity generated in Slovenia. Wind, solar, hydro, nuclear and bioenergy together made 74% of generation in Slovenia.

Questions about the electricity price in Slovenia
- What does electricity cost in Slovenia today?
- In SI (SI) the spot price averages 21.5 c/kWh today. It is cheapest at 13–14 with 14.1 c/kWh and dearest at 07–08 with 29.1 c/kWh. Network tariffs, taxes and VAT come on top.
- What does an ordinary household in Slovenia pay for electricity?
- A household in Slovenia using 2,500–5,000 kWh a year paid 21.2 c/kWh per kWh on average, all-in, in H1 2026, according to Eurostat. The price varies with the network company and the contract.
- How much of the electricity in Slovenia comes from nuclear?
- 35% of the electricity generated in Slovenia came from nuclear in 2024 (Eurostat), the largest single source.
- Who owns the Krško nuclear power plant?
- Krško was built jointly by Slovenia and Croatia when both were part of Yugoslavia. Today it is owned in equal shares by the Slovenian company GEN energija and Croatia's HEP, and each receives half of the electricity. After independence the two countries settled the arrangement in an intergovernmental treaty, which also covers decommissioning and waste.
- What are the time blocks on a Slovenian network bill?
- Since the 2024 reform, the network charge is split into five time blocks. The highest rates apply on working days in the winter season at the morning and evening peaks; the lowest at night and at weekends outside winter. Each block also has an agreed power, and exceeding it costs extra, so households with heat pumps or electric cars feel the timing most.
- Why is the Slovenian price often close to Austria's or Italy's?
- Slovenia's grid is tightly linked to its neighbours, and the hourly price is set jointly in the European market coupling. As long as there is free capacity, prices converge. When the lines to Italy are full, Slovenia usually lines up with the cheaper side to the north and east; when they are not, Italian prices pull Slovenia up.
