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 figures were accompanied by higher cross-border electricity movements.
Conventional and nuclear output changes
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 by 19% year on year to 228 GWh.
The rise in wind and solar did not offset the lower conventional generation. Slovenia’s electricity balance therefore relied more heavily on imports during the month.
Imports, exports and consumption patterns
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 August. Household electricity consumption reached 251 GWh, up 7% from July.
Commercial consumption declined 4% to 593 GWh. The August data show how weaker hydro and conventional generation can change Slovenia’s cross-border position even as renewable capacity expands.
Regional flows during tighter hydro availability
For the regional market, Slovenia’s import requirement increases the importance of available flows from Austria, Hungary, Croatia, and Italy. This is particularly relevant during periods of tighter hydro availability.
The August pattern reflects shifts across generation sources and trade flows within the same reporting month. It also aligns with the observed changes in thermal, hydropower, nuclear output, and wind and solar generation levels.
