Southeast European electricity markets staged a broad rebound on 19 May 2026, with strong price recovery visible across the Balkans and Hungary after the previous session’s softer weekend dynamics, as regional consumption accelerated sharply while cross-border imports into the SEE system rose above 835 MW net.
The most aggressive daily moves were recorded in the lower-priced Balkan markets. Serbian SEEPEX prices jumped by almost 41 % day-on-day to EUR 123.23/MWh, while Montenegro’s BELEN market rose 24.6 % to EUR 108.84/MWh. North Macedonia’s MEMO climbed 26.3 % to EUR 113.22/MWh, while Albania’s ALPEX recovered to EUR 77.29/MWh despite remaining the lowest-priced market in the region.
Hungary’s HUPX remained the regional pricing anchor at EUR 141.79/MWh, only marginally lower day-on-day, while Romanian OPCOM closed at EUR 142.69/MWh, effectively maintaining full correlation with Hungarian pricing. Slovenia’s BSP and Croatia’s CROPEX remained tightly coupled with Central European fundamentals near EUR 140/MWh, confirming continued integration between SEE and core continental markets.
The underlying driver of the rebound was a major increase in system demand. Regional consumption climbed to 28,647 MW, up by almost 1,500 MW from the previous day, while imports into the SEE-Hungary balancing area surged by more than 1 GW day-on-day.
The import structure remains strategically important. Core inflows from Austria and Slovakia toward Hungary and Southeast Europe rose to more than 1,065 MW, highlighting continued structural dependence of SEE markets on Central European balancing capacity during volatile renewable output periods.
At the same time, renewable generation dynamics shifted materially. Solar production recovered strongly to 5,710 MW, rising by almost 945 MW day-on-day, partially offsetting a sharp collapse in wind generation, which fell by more than 700 MW to 2,033 MW.
This divergence between solar and wind output continues to define spring market volatility across SEE. Solar production remains increasingly dominant during midday hours, suppressing intraday pricing, while weak evening wind conditions continue to create steep evening ramp pricing between 19:00–22:00 CET. Hourly curves across HUPX, BSP, OPCOM and HENEX all showed strong evening price spikes above EUR 230–260/MWh during peak balancing hours.
Hydro production also strengthened materially, reaching 7,366 MW, supported by elevated Danube flows near 6,839 m³/s, significantly improving hydro flexibility across Romania and the wider Danube-connected system.
Coal and gas generation both increased simultaneously, reflecting the system’s growing need for conventional flexibility despite rising renewable penetration. Coal generation reached 4,601 MW, while gas-fired generation rose to 3,510 MW.
Forward markets nevertheless weakened modestly despite stronger spot conditions. Hungarian week-ahead baseload contracts declined toward EUR 102/MWh, while June-2026 Hungarian baseload forwards eased toward EUR 112/MWh, suggesting traders continue pricing expectations of stronger solar availability and softer continental gas fundamentals later in the quarter.
Gas markets remained relatively stable, with Austrian CEGH front-month contracts near EUR 51.92/MWh, while EU carbon allowances held above EUR 75/tCO₂, maintaining continued structural pressure on coal-fired marginal generation economics across SEE markets.
The widening divergence between Southern Balkan pricing and Central Europe also remains notable. Greece’s HENEX market surged almost 30 % day-on-day to EUR 129.48/MWh, although still trading at a discount to Hungary due to stronger domestic renewable output and improving interconnection balances.
Commercial flow data continues to illustrate the increasingly fragmented structure of regional balancing. Romania remained a major exporter toward Hungary, averaging more than 1,200 MW over the last seven days, while Greece continued exporting strongly toward Turkey. Bosnia and Herzegovina maintained exports toward both Serbia and Montenegro, highlighting the ongoing importance of hydro and lignite flexibility within the western Balkan system.
