SEE daily data for 30 June 2026 show a sharp scarcity-driven repricing across the northern and central corridor. Hungary’s HUPX cleared at €290.71/MWh, up €68/MWh day on day, while Romania’s OPCOM reached €293.44/MWh, up €69.9/MWh. Romania was the highest-priced market in the monitored set.
Serbia also moved higher, with SEEPEX rising to €250.98/MWh, up €101/MWh. Croatia and Slovenia cleared close to Hungary at €263.03/MWh and €262.05/MWh. The price spread across markets remained wide, with Albania at €116.33/MWh, Greece at €137.72/MWh, Bulgaria at €148.44/MWh, North Macedonia at €148.05/MWh, and Montenegro at €157.14/MWh.
Regional demand, net imports and Core inflows
The same session reflected higher demand alongside tighter system conditions. Regional HU+SEE consumption increased to 35,949 MW, up 1,175 MW from the previous day, while the system net import position deepened to 2,859 MW, up 1,023 MW. Imports from the Core direction, mainly AT+SK into HU+SI, reached 2,946 MW.
The HU-DE spot spread widened to €103.38/MWh. This indicated a stronger scarcity signal in Hungary relative to Germany for the day.
Evening ramp drives hourly maxima across markets
The hourly pattern showed that the highest prices were concentrated in the evening ramp rather than in the solar-heavy midday period. Hungary’s HUPX reached a maximum of €923.10/MWh at H21. Romania reached €954.60/MWh at H21, while Croatia cleared at €946.60/MWh.
Slovenia recorded a maximum of €1,041.50/MWh, also in the evening interval, and Serbia reached €800/MWh. In several markets, off-peak averages were higher than peak averages; for Hungary, off-peak cleared at €320.80/MWh, above the peak average of €260.60/MWh.
This structure was linked to evening scarcity hours falling outside the standard peak block in the dataset provided . The session data also point to a summer ramp profile where solar supports midday balance but post-solar hours become exposed to import constraints and cross-border congestion.
Bilateral balances: Hungary, Romania and Croatia short; Greece exports northward
The country balance figures show where shortages were concentrated across the corridor. Hungary was the largest importer at 1,841 MW, with consumption of 5,819 MW and domestic generation of only 3,977 MW. Romania also ran short with consumption of 6,605 MW, generation of 5,225 MW, and net imports of 1,380 MW.
Croatia remained heavily short as well, importing 1,336 MW against consumption of 2,814 MW and generation of 1,478 MW. Serbia imported 697 MW, with consumption of 4,046 MW and generation of 3,348 MW.
The lower-priced side included Greece and Bulgaria. Greece exported 1,620 MW, with consumption of 7,425 MW and generation of 9,045 MW; its prior-day detailed balance line included gas output of 000
