Drought and Heat Drive Up Electricity Prices in Slovenia

Slovenia, like much of Europe, is experiencing a significant impact on its electricity generation due to prevailing heatwaves and drought conditions. The Sava River's flow in its lower reaches is approximately half of what it was last year, and daily temperatures are nearing critical limits for the smooth operation of nuclear power plants.

This environmental strain has led to a substantial decrease in hydroelectric power output. Coupled with reduced generation from nuclear facilities, the energy sector is increasingly relying on solar power, which saw its share rise to 25% in June, and costly thermal power plants. Hydroelectric power, once a more significant contributor, ranked fourth in June's generation mix, behind wind power.

The consequence of these production challenges and the higher cost of fossil fuels has been a sharp increase in daily electricity prices. These prices have roughly doubled compared to the same period in the previous year. The European Union's interconnected energy system, despite its diverse generation sources, is being tested this summer by these combined factors, leading to market volatility and higher costs for consumers.
