April withdrawals on the transmission network
Electricity consumption in Slovenia declined slightly in April, with total withdrawals from the transmission network reaching 809.3 GWh. The figure represented a modest decrease compared with both the same month last year and initial forecasts. The monthly pattern was driven by changes across specific consumer groups.
Industrial and commercial demand below projections
The largest deviation from projections came from direct industrial and commercial consumers. This group drew 85.4 GWh from the network during the month, equivalent to a 5.2% year-on-year decline. It also fell nearly 15% below expectations set out in the national energy balance.
Stable distribution use and pumped-storage consumption
Distribution companies recorded relatively stable usage levels, accounting for most overall consumption. Their combined withdrawals totaled 686.5 GWh, only marginally below the volume registered in April of the previous year. Demand linked to pumping at the Avče pumped-storage hydropower plant also remained broadly stable.
The Avče facility consumed 37.4 GWh for pumping, showing only a slight increase versus April 2025. This points to steady operational use of energy storage capacity during the month.
First four months of 2026 show continued growth
Despite the April decline, electricity demand in Slovenia continued an upward trajectory in the broader trend. During the first four months of 2026, total consumption on the transmission network reached 4,053 GWh. That level exceeded the same period last year by 2.8%.
Cumulative demand also ran above planning assumptions, with consumption between January and April nearly 2% higher than projected. Growth was recorded across all major consumer categories during the first four months of the year.
Category-by-category withdrawals through April
Distribution system operators increased withdrawals to 3,592.1 GWh, up 2.7% year-on-year. Direct consumers reached 324.2 GWh, a 4.9% increase. Electricity used by HPP Avče rose by 2.7% to 136.7 GWh.
