Supported byClarion Energy

In Week 27 of 2025, electricity market prices surged across all Southeast European (SEE) countries compared to the previous week, exceeding €100/MWh in most markets despite stable gas prices. The increase was driven by higher electricity demand due to a heatwave affecting Europe and a drop in wind energy production. Prices started the week around €100/MWh in all SEE countries, peaked on Tuesday, July 1, surpassing €100/MWh, and declined towards the end of the week. Croatia and Hungary experienced the highest percentage increases in electricity prices, rising by 18.83% and 16.12% respectively, followed by Romania with a 12.35% increase. Bulgaria, Italy, and Greece saw smaller single-digit price rises of 6.12%, 4.73%, and 1.24%, respectively.

During the first week of July 2025, weekly average spot electricity prices in Central Europe showed a uniform trend, with all markets experiencing price increases. Prices hovered around €95/MWh for most major Central European countries, ranging between €76/MWh and €112/MWh. Slovenia was the most expensive market, with an average price of €111.83/MWh, reflecting an 18.77% growth from Week 26. Slovakia followed with an average of €103.49/MWh. At the lower end, France recorded the lowest price in Central Europe at €75.50/MWh, marking a significant weekly increase of 23.20%.

In Week 27 of 2025, the European weekly average electricity price was approximately €99/MWh, ranging from €75.50/MWh in France to €122.82/MWh in Italy. In the MIBEL markets, prices rose modestly: Spain’s price increased by 4.48% to €91.70/MWh, and Portugal reached the same price, with a 4.39% increase. In Southern Europe, all SEE countries recorded prices above €100/MWh, except Bulgaria and Greece, which had lower prices. Prices across the region ranged from €57/MWh to €123/MWh. Türkiye had the lowest weekly average price at €56.73/MWh, followed by Greece at €93.41/MWh, making it the second cheapest SEE market in the first week of July. Italy posted the highest average price at €122.82/MWh, a 4.73% increase from the previous week, followed by Croatia at €110.31/MWh, the second most expensive market in the SEE region.

Regarding daily prices, most SEE electricity markets peaked on Monday, June 30, while the lowest prices were observed on Sunday, June 6. Electricity demand in the SEE region rose sharply in Week 27 compared to the previous week, fueled by an intense heatwave across Southern Europe. Record-high temperatures during the first days of the week significantly increased electricity demand. Overall, electricity consumption in the SEE region grew by 2.58% compared to Week 26, reaching 17,808.62 GWh. Croatia and Italy recorded the largest demand increases at 37.19% and 6.88%, respectively, followed by Bulgaria and Greece. Some countries, including Türkiye, Romania, and Hungary, maintained demand levels similar to the previous week, with minor fluctuations.

Electricity generation from variable renewable sources in SEE markets decreased by 1.8% compared to Week 26, totaling 4,033.25 GWh. This decline was mainly due to a significant drop in wind power production, while solar generation increased moderately. Wind generation across the region fell by 12.1%, amounting to 1,649.47 GWh. Most SEE countries experienced lower wind output, except Greece, with Italy and Romania seeing the largest declines of 55.9% and 33.8%, respectively. Conversely, solar generation rose by 7.0% week-on-week, reaching 2,383.58 GWh, with moderate increases in Italy (11.1%) and Bulgaria (8.5%).

Hydropower production in the SEE region fell by 4.54% in Week 27 compared to Week 26, totaling 2,315.09 GWh. The overall decline was due to reduced hydropower output in about half of the SEE countries. Bulgaria, Serbia, Türkiye, and Croatia saw decreases of 27.33%, 18.98%, 7.05%, and 0.6%, respectively, while other countries recorded increases. Hungary and Romania experienced the highest growth rates in hydropower generation, rising by 41.20% and 15.98%, respectively.

Thermal power generation in SEE markets surged by 12.93% in Week 27 compared to Week 26, driven by higher electricity demand. Total thermal output reached 8,537.37 GWh, with increases in both coal- and gas-fired generation. Coal-fired production rose by 2.45% to 3,377.77 GWh, while gas-fired generation increased more sharply by 21.03%, reaching 5,159.60 GWh. At the country level, Türkiye saw a 1.19% increase in coal generation and a 4.33% rise in gas-fired output. Bulgaria recorded a 4.30% increase in coal generation and a 2.24% rise in gas-fired production. Greece experienced a significant surge in coal electricity generation, up 127.55%, accompanied by a 1.94% increase in gas-fired generation.

Cross-border electricity trade in the SEE region saw net imports rise by 3.38% in Week 27 compared to Week 26, totaling 1,313.12 GWh. Electricity exports from the region increased sharply by 82.8%, reaching 353.27 GWh, while imports grew by 13.9%, totaling 1,667.39 GWh. Serbia, Italy, and Romania experienced notable increases in net imports by 39.78%, 17.92%, and 12.50%, respectively. In contrast, Hungary’s net electricity imports fell by 85.23%. Greece and Bulgaria maintained their exporting activities from the previous week, registering net exports of 134.89 GWh and 150.64 GWh, respectively. Additionally, Türkiye reversed its trade position to become a net exporter in Week 27, with net exports amounting to 67.74 GWh.
