Slovenia’s electricity consumption on 4 May 2024 entirely from renewables

In the first three days of May, most of Slovenia’s electricity consumption was covered by renewable energy sources, while on 4 May 2024, the electricity generated from renewables even exceeded daily consumption.

On 1 and 2 May, nearly all electricity generated in Slovenia was from renewable energy sources, with both the Krško Nuclear Power Plant and the Šoštanj Thermal Power Plant being out of operation.

In the first days of May, most electricity in Slovenia was produced from renewable energy sources. The data is available only for the transmission network, meaning that production from dispersed renewable power plants (solar power plants, small hydroelectric power plants and wind power plants) connected to the distribution network is not included in the percentages shown below. In other words, even more electricity needs were covered by renewables than shown in the official statistics; at the end of March, there were over 46,000 individual self-sufficient solar power plants, whose production is not included in the Eles statistics below.

On 4 May 2024, the total daily electricity consumption in Slovenia, excluding the Avče Pumped-Storage Hydropower Plant, was covered by renewable energy sources. In the first four days of May, 79.4% of total electricity consumption was covered by renewables. The data is encouraging and indicates a positive trend.

Daily balance for the first four days of May 2024: electricity consumption covered by renewables.

Remark: Excluding losses on the transmission network, as well as electricity generated in the distribution network and the consumption of this electricity in the distribution network.

The data refers to the daily level. As for the hourly level, Slovenia exports its electricity during certain hours, when it generates more power than it uses, and imports part of it when consumption exceeds production. Increasing self-sufficiency in these hours would require greater integration of energy storage facilities and systems, particularly pumped-storage hydropower plants, and larger, systemic battery storage systems with sufficient power and capacity to store the energy. This would allow us to store more energy during those hours of the day when generation exceeds consumption and use it when generation is lower than consumption.

During this Government’s term, Slovenia has achieved incredible growth in solar energy use, more than doubling its total capacity from 1 June 2022 to the end of 2023. Growth in solar power plant production capacities in 2023 was the highest in the European Union in terms of added capacity per capita, thus closing the gap in achieving its renewable energy targets. This trend should be continued in the future.
