According to data from the Statistical Office of the Republic of Slovenia, the country’s net electricity generation in April 2026 declined by 15% year-on-year, reflecting weaker overall production conditions across the power system.
In April 2026, total net electricity generation in Slovenia reached 1,070 GWh, which represents a 17% decrease compared to the previous month.
Production from thermal power plants fell by 16% year-on-year, reaching 165 GWh. Output from hydropower plants saw a much sharper decline of 48%, down to 219 GWh, reflecting significantly weaker hydro conditions. In contrast, production from the Krško nuclear power plant remained broadly stable at 501 GWh, providing a steady baseload contribution.
Generation from wind and solar power plants increased by 33%, reaching 184 GWh, indicating continued expansion of renewable capacity despite overall system contraction.
On the trade side, Slovenia imported 860 GWh of electricity, which is 22% more than in April 2024, while exports amounted to 854 GWh, representing a 7% decrease. This left the system close to balanced but increasingly dependent on imports under lower domestic hydro output conditions.
On the consumption side, electricity demand also weakened. Household consumption fell to 255 GWh, down 16% compared to the previous month, while consumption by commercial users dropped to 546 GWh, or 10% lower than in March.
In the broader energy commodity segment, supply trends were mostly negative in April. The only notable increases were recorded in other petroleum products (+57%), kerosene (+57%), petrol (+22%), and heating oil (+12%).
At the same time, significant declines were observed across several fuels, including lignite and brown coal (-65%), LPG (-20%), natural gas (-16%), coke (-13%), and hard coal (-10%), indicating a general contraction in fossil fuel supply volumes during the month.
