The month of January has proven to be exceptionally challenging for Slovenia’s electricity sector, as it was classified among the coldest January periods in the last decade by the Slovenian Environment Agency. This severe weather has led to a notable increase in electricity demand, particularly highlighted by a peak consumption period on January 8, when temperatures dropped below freezing in the morning hours.
During this month, Slovenia’s total electricity consumption from the transmission network reached an impressive 1,271.8 GWh. This figure represents a 12.8% increase compared to January 2025 and exceeds initial demand forecasts by 11.7%. The growth trend was consistent across all monitored consumer categories, indicating widespread impacts on energy usage.
The majority of this demand surge can be attributed to distribution companies, which accounted for 1,165 GWh of the total consumption—marking a year-on-year increase of over 13% and surpassing projections by more than 14%. Additionally, large direct consumers contributed significantly with a total draw of 69.8 GWh, reflecting a rise of 10.6% from the previous year. The pumped-storage hydropower plant Avce also reported an uptick in operations, utilizing 37 GWh for pumping activities, which is an annual increase exceeding 8%.
This data underscores the heightened sensitivity of Slovenia’s electricity system to winter conditions, demonstrating how abrupt temperature declines can lead to immediate spikes in network demand. As such fluctuations continue to challenge energy providers and regulators alike, they highlight the necessity for robust planning and infrastructure resilience within Slovenia’s energy landscape.
