Electricity consumption in Slovenia declined slightly in April, with total withdrawals from the transmission network reaching 809.3 GWh. The April figure was lower than both the same month last year and initial forecasts. The data point to a modest monthly decrease across the system.
Industrial and commercial demand falls versus projections
The largest divergence from projections came from direct industrial and commercial consumers. This segment drew 85.4 GWh from the network during the month. It represented a 5.2% year-on-year decline and was nearly 15% below expectations set out in the national energy balance.
Distribution companies recorded relatively stable electricity use during the same period. Their combined withdrawals totaled 686.5 GWh, only marginally below the volume registered in April of the previous year. The figures align with steady household and retail electricity demand across Slovenia.
Pumped-storage pumping remains steady at Avče
Electricity demand associated with pumping operations at the Avče pumped-storage hydropower plant also stayed broadly stable. The facility consumed 37.4 GWh for pumping in April. This was only slightly higher than in April 2025, indicating continued steady use of storage capacity.
First four months show higher consumption and category growth
Despite the April decline, electricity demand in Slovenia remains on an upward trajectory in the broader trend. Total consumption on the transmission network reached 4,053 GWh during the first four months of 2026. That level exceeded the same period last year by 2.8%.
Cumulative demand also ran above planning assumptions for the January-to-April period. Consumption was nearly 2% higher than projected, reflecting stronger-than-expected electricity use across key sectors of the economy. Growth was recorded across all major consumer categories during the first four months of the year.
Distribution system operators increased withdrawals to 3,592.1 GWh, up 2.7% year-on-year. Direct consumers reached 324.2 GWh, a rise of 4.9%. Electricity used by HPP Avče increased by 2.7% to 136.7 GWh, according to the latest figures.
The latest data show that while April brought a temporary slowdown, Slovenia’s electricity consumption trend remains positive for 2026 demand growth expectations.
