Slovenia’s net electricity generation fell 13% year on year in August to 919 GWh. Production was also 7% lower than in July. The month’s output changes were reflected in cross-border electricity flows.
Conventional and nuclear generation trends
Thermal generation declined 42% year on year to 42 GWh, while hydropower fell 33% to 191 GWh. Output from the Krsko nuclear power plant decreased 9% to 458 GWh. Wind and solar increased during the same period.
Wind and solar rose 19% year on year to 228 GWh. The higher variable generation did not fully compensate for lower conventional output. As a result, Slovenia’s overall generation position shifted relative to regional supply needs.
Imports, exports and electricity demand
Slovenian electricity imports increased 12% year on year to 869 GWh, while exports fell 14% to 716 GWh. This combination widened Slovenia’s dependence on neighbouring markets during the month. Household electricity consumption reached 251 GWh, up 7% from July.
Commercial consumption declined 4% to 593 GWh. The August figures showed how weaker hydro and conventional generation can change Slovenia’s cross-border position even as renewable capacity expands. For the regional market, Slovenia’s import requirement increases the importance of available flows from Austria, Hungary, Croatia and Italy, particularly during periods of tighter hydro availability.
