In specific market movements, Hungary’s HUPX day-ahead baseload price dropped to €120.07/MWh, reflecting a decrease of €16.5/MWh from the previous day. Similarly, Romania’s OPCOM closed at €121.10/MWh, also down by over €16/MWh. Other markets saw comparable declines, with Slovenia’s BSP at €110.66/MWh, Croatia’s CROPEX at €113.13/MWh, and Montenegro’s BELEN falling sharply to €100.32/MWh. Greece maintained the lowest price among major markets at €94.38/MWh, attributed to favorable solar conditions and diminished peak demand pressures. Conversely, Serbia’s SEEPEX registered an increase to €115.27/MWh, indicating ongoing structural tightness in its balancing position relative to neighboring exchanges.
The broader regional power dynamics revealed a significant uptick in imports into the HU+SEE system, with net imports reaching approximately 926 MW—an increase of nearly 1 GW day-on-day. Notably, core imports from Austria and Slovakia surged to 1,140 MW, driven by favorable west-to-east flow economics as the spread between Hungarian and German markets widened beyond €25/MWh.
Generation statistics underscored that the observed market softening was predominantly driven by renewable sources. Total electricity generation across SEE rose by approximately 1.7 GW day-on-day to reach 28,069 MW. Solar output alone increased to 5,543 MW while hydro generation climbed to 6,542 MW. Wind generation remained stable above 3.5 GW, contributing to midday price compression across the region. Thermal coal generation also saw an uptick to 4,486 MW, suggesting that thermal units remained economically viable despite lower spot prices.
The intraday pricing structure highlighted increasing volatility within SEE electricity markets, with prices collapsing during solar-rich midday hours before rebounding sharply during evening peaks, often exceeding €180-260/MWh in several markets. Serbia’s SEEPEX maintained higher minimum prices compared to its neighbors, with daily minimums still above €50/MWh, reflecting limited domestic flexibility and ongoing reliance on balancing measures.
Cross-border commercial flow data confirmed Serbia’s role as a pivotal transit and balancing hub within the region. Average flows indicated robust imports from Hungary into Serbia at around 922 MW baseload and 724 MW peak over the past week. Additionally, corridors from Bulgaria and Bosnia into Serbia remained active, while Romania continued its strong export activity towards Hungary, reinforcing established north-south flow patterns across Central and Southeast Europe.
Fuel market dynamics provided further bearish support for electricity pricing. Austrian CEGH gas for June trading was reported at approximately €48.23/MWh, marking a decline for the day, while EUA carbon prices eased toward €75/t. Softening coal futures contributed to lowered marginal thermal generation costs throughout the region.
The evolving landscape of SEE power markets is increasingly characterized by solar expansion and heightened risks of midday oversupply. Initiatives such as Romania’s PPC Energie pilot project—offering households free electricity during peak solar periods—illustrate how utilities are adapting demand patterns in response to renewable generation profiles. Concurrently, EVN Macedonia’s recent commissioning of a 10 MW / 20 MWh battery storage system at Probistip signifies growing investments in balancing infrastructure as market volatility intensifies.
Hydrological conditions remain favorable for hydroelectric production across the Balkan region due to sustained elevated Danube flow indicators relative to long-term averages; this situation helps mitigate upward pressure on regional spot prices.
As traders and generators navigate this evolving market landscape, they face a transition towards a more fragmented pricing structure characterized by pronounced solar-driven intraday troughs and aggressive evening ramps. The widening disparity between midday and evening pricing is emerging as a central theme in SEE electricity trading dynamics moving forward into 2026, particularly impacting operators reliant on flexible gas, hydro resources, and future battery storage solutions. Key markets such as Serbia, Romania, and Hungary are positioned as critical volatility anchors due to their unique blend of renewable growth trajectories and interconnection dependencies alongside thermal balancing needs.
