Recent data from the Statistical Office of the Republic of Slovenia indicates that the nation’s net electricity generation experienced a 2% decline in November 2025, totaling 1,315 GWh. This figure represents a significant increase of 63% compared to October 2025, highlighting notable fluctuations in the energy mix.
A detailed analysis of the generation sources reveals that thermal power production saw a substantial decrease of 18% year-on-year. In contrast, hydropower output rose by 10%, while the Krško nuclear power plant maintained stable production levels compared to the previous year. The most striking development was a remarkable 50% surge in wind and solar generation, underscoring the ongoing expansion of renewable energy capacity in Slovenia.
The country’s electricity imports totaled 787 GWh, reflecting a decrease of 7% from the previous year. Exports also fell by 7%, amounting to 908 GWh. On the consumption front, household electricity usage climbed to 314 GWh, marking a significant increase of 15% from October, while commercial consumption rose to 657 GWh, up by 12%.
The overall supply of energy commodities exhibited a downward trend, with exceptions noted in certain categories. Notably, supplies of natural gas, other petroleum products, and coke increased by 15%, 13%, and 3%, respectively. Conversely, there were marked declines in supplies of kerosene (-42%), heating oil (-35%), hard coal (-16%), petrol (-8%), LPG (-8%), and diesel (-7%). Year-on-year comparisons reveal that lignite and brown coal supply dropped by 41%, hard coal by 23%, heating oil by 7%, LPG by 6%, and diesel by 3%.
This shift in Slovenia’s energy landscape reflects broader trends towards renewable energy adoption while also indicating challenges within traditional energy sectors. The decline in thermal power generation raises questions about future energy policy and market dynamics as Slovenia navigates its transition to a more sustainable energy framework.
