Slovenia’s electricity consumption from the transmission network has shown a consistent decline, reflecting broader trends in energy demand. In the first eleven months of 2025, the total electricity drawn reached just over 9.8 TWh, indicating a 0.9% decrease compared to the same period in 2024. This trend underscores ongoing shifts in energy usage patterns within the country.
Monthly data reveals a steady reduction in consumption, with November figures showing network withdrawals of approximately 1,035.6 GWh, nearly 2% lower than in November of the previous year. Cumulatively, from January through November 2025, total electricity taken from the transmission system was recorded at 9,824.5 GWh, slightly below last year’s levels and reflecting a persistent decline.
The bulk of this demand came from distribution companies, which accounted for around 8,553.8 GWh during the eleven-month period. This figure exceeded initial energy balance projections by about 1%, yet still represented a decline of 2% compared to the same timeframe in 2024. In contrast, direct consumers withdrew 868 GWh, surpassing last year’s levels by nearly 3%, although this remained over 8% below original forecasts.
Interestingly, the Avče pump-storage hydropower plant stood out as an exception to the overall downward trend. Electricity used for pumping operations surged to 402.8 GWh, marking an increase of almost 18% year-on-year and exceeding initial projections by more than 19%. This uptick highlights specific operational dynamics within Slovenia’s energy landscape.
<pFor context, total electricity drawn from Slovenia’s transmission network in 2024 was recorded at 11,024.7 GWh, slightly below levels seen in 2023. The current figures suggest that the gradual decline in transmission-level demand is likely to persist into 2025.
Several factors contribute to this ongoing development: improvements in energy efficiency across various sectors, a slowdown in industrial output, and a notable rise in individual and community-owned solar installations. These installations are increasingly reducing reliance on the national grid and reshaping energy consumption patterns throughout Slovenia.
