In the first half of 2024, Slovenia experienced a 3.3% decrease in electricity consumption compared to the same period last year, according to ELES, the Slovenian electricity transmission system operator.
Key consumption trends:
- Overall consumption: 4.9% lower, with consumption from the transmission network down by 6.2%.
- June 2024: Electricity consumption was 2.5% lower year-on-year. Large consumers connected to the transmission network saw an 11% increase in consumption, while distribution network consumption was 3.7% lower.
- Self-sufficiency: Increasing use of solar energy has affected household consumption data. For the first half of 2024, households reduced their electricity consumption by about 6% according to official records, but actual consumption, including self-generated solar power, was only 2% lower compared to the same period last year.
- Solar power impact: Installed solar capacity increased from an average of 357 MW in H1 2023 to 595 MW in H1 2024, producing an estimated 313 GWh of electricity with 156 GWh consumed by owners.
Comparative data:
- First half of 2024 vs. pre-pandemic 2019: Consumption on the transmission network was 55.3% lower, distribution network consumption was 8.2% lower, and total consumption was 15.5% lower.
- June 2024 vs. June 2019: Overall consumption was 18.5% lower, with a 52% decrease on the transmission network and a 12% decrease on the distribution network. Shutdown of primary aluminum production at Talum contributed to nearly 30% of this decline.
Household consumption: While officially reported as 5% lower compared to the first half of 2019, actual consumption, including solar self-consumption, was about 2% higher. This increase is partly attributed to Slovenia’s lower electricity prices compared to other EU countries.
