Slovenia’s net electricity production fell by 9% year on year in July 2026, as sharply lower hydropower and thermal generation outweighed further growth in wind and solar output.
Total net production reached 996 GWh, also 13% lower than in June, according to figures cited from the Statistical Office of the Republic of Slovenia. SEE-
Thermal power generation dropped 41% year on year to 47 GWh, while hydropower production declined 35% to 212 GWh.
Output from the Krško nuclear power plant fell by a more modest 2%, reaching 497 GWh.
Wind and solar moved in the opposite direction, with combined production increasing 30% to 240 GWh.
The weaker domestic generation balance was reflected in cross-border electricity flows. Slovenia imported 1.035 TWh, around 1% more than in July 2025, while exports fell 15% to 897 GWh.
Household electricity consumption reached 234 GWh, up 1% from June, while commercial consumers used 618 GWh, representing a 4% monthly increase.
The wider energy-supply data also weakened. Compared with June, heating-oil supply fell 40%, LPG dropped 16%, hard coal decreased 2% and natural-gas supply declined 2%.
On an annual basis, heating-oil supply was down 53%, LPG 34%, hard coal 19%, kerosene 16% and natural gas 8%.
The July figures highlight Slovenia’s continued exposure to hydrological conditions. Higher renewable output from wind and solar helped partly compensate for the decline in conventional generation, but reduced hydro production and lower thermal availability ultimately left the country more reliant on imported electricity.
