On May 19, 2026, Southeast European electricity markets demonstrated a notable recovery, with prices rising sharply across the Balkans and Hungary. This rebound followed a weekend characterized by softer market dynamics, driven by a substantial increase in regional consumption and a surge in cross-border imports exceeding 835 MW net.
The Serbian SEEPEX market recorded the most pronounced increase, with prices soaring by approximately 41% day-on-day to reach EUR 123.23/MWh. Montenegro’s BELEN market also saw significant gains of 24.6%, closing at EUR 108.84/MWh. Similarly, North Macedonia’s MEMO climbed by 26.3% to EUR 113.22/MWh, while Albania’s ALPEX rose to EUR 77.29/MWh, maintaining its position as the lowest-priced market in the region.
Hungary’s HUPX continued to serve as the regional pricing benchmark at EUR 141.79/MWh, showing only a slight decrease from the previous day. Romanian OPCOM prices were closely aligned, closing at EUR 142.69/MWh, indicating strong correlation with Hungarian pricing trends. Slovenia’s BSP and Croatia’s CROPEX also remained linked with Central European market fundamentals around EUR 140/MWh, underscoring the ongoing integration of SEE markets with core continental dynamics.
The primary catalyst for this price surge was a significant uptick in system demand, which rose to 28,647 MW—an increase of nearly 1,500 MW from the previous day. Concurrently, imports into the SEE-Hungary balancing area surged by over 1 GW day-on-day, reflecting heightened reliance on external supply sources.
Import dynamics remain critical for regional stability; inflows from Austria and Slovakia toward Hungary and Southeast Europe surpassed 1,065 MW. This trend highlights the persistent dependence of SEE markets on Central European balancing capacities during periods of fluctuating renewable energy output.
Renewable generation saw marked shifts as well; solar output rebounded significantly to reach 5,710 MW—an increase of nearly 945 MW compared to the previous day—partially compensating for a sharp decline in wind generation which fell below 2,033 MW by more than 700 MW. This disparity between solar and wind production is becoming increasingly influential in shaping springtime market volatility across SEE.
Solar generation dominated midday hours effectively suppressing intraday pricing while weak evening wind conditions contributed to substantial price spikes during peak hours between 19:00 and 22:00 CET. Hourly pricing curves across HUPX, BSP, OPCOM, and HENEX exhibited spikes exceeding EUR 230–260/MWh during these critical balancing periods.
In addition to renewables, hydroelectric production experienced a significant boost reaching levels of 7,366 MW due to elevated Danube flows averaging around 6,839 m³/s; this improvement enhances hydro flexibility across Romania and neighboring regions connected to the Danube system.
Conventional generation sources also saw increases; coal-fired power output reached approximately 4,601 MW while gas generation rose to about 3,510 MW. This simultaneous rise indicates an increasing demand for traditional energy sources amid growing renewable penetration in the overall energy mix.
Despite stronger spot market conditions observed recently, forward markets reflected a modest weakening trend. Hungarian week-ahead baseload contracts dipped toward EUR 102/MWh while June-2026 Hungarian baseload forwards eased toward EUR 112/MWh—suggesting that traders are factoring in expectations for improved solar availability and softer continental gas fundamentals later in the quarter.
Gas markets showed relative stability with Austrian CEGH front-month contracts hovering around EUR 51.92/MWh; meanwhile EU carbon allowances remained above EUR 75/tCO₂ exerting continued pressure on coal generation economics within SEE markets.
A notable divergence persists between pricing in Southern Balkan markets compared to Central Europe; Greece’s HENEX market surged almost by 30% day-on-day to reach EUR 129.48/MWh but continues trading at a discount relative to Hungary owing to stronger domestic renewable outputs and enhanced interconnection balances.
Commercial flow data underscores an increasingly fragmented regional balancing structure; Romania has emerged as a key exporter towards Hungary averaging over 1,200 MW over the past week while Greece maintains robust exports towards Turkey. Bosnia and Herzegovina continues its export activities towards both Serbia and Montenegro highlighting the essential role of hydro and lignite resources within the Western Balkan energy landscape.
