Data from the Statistical Office of the Republic of Slovenia show that net electricity generation in April 2026 fell by 15% year-on-year. The same release reports that total net generation reached 1,070 GWh. Compared with the previous month, this level was 17% lower.
Thermal power output declined by 16% year-on-year to 165 GWh. Hydropower generation dropped more sharply, falling 48% to 219 GWh. Production from the Krško nuclear power plant stayed broadly stable at 501 GWh.
Wind and solar generation rises while system output contracts
Generation from wind and solar power plants increased by 33%, reaching 184 GWh. This rise occurred alongside lower overall net electricity generation. The figures indicate that renewable output grew while other segments contracted during the month.
Electricity trade and demand trends in April 2026
Slovenia imported 860 GWh of electricity in April 2026, which was 22% higher than in April 2024. Exports totaled 854 GWh, down 7%. Together, the trade balance remained close to even while imports were higher than a year earlier.
Electricity demand also weakened during the month. Household consumption fell to 255 GWh, down 16% versus the previous month. Consumption by commercial users declined to 546 GWh, which was 10% lower than in March.
April commodity supply changes across petroleum and fuels
Supply trends across the broader energy commodity segment were mostly negative in April. The only increases reported were for other petroleum products (+57%), kerosene (+57%), petrol (+22%) and heating oil (+12%).
The report also recorded declines across multiple fuels. Lignite and brown coal fell by -65%, LPG by -20%, natural gas by -16%, coke by -13%, and hard coal by -10%. These changes point to reduced fossil fuel supply volumes during the month.
