Serbian day-ahead electricity prices for delivery on 2 October fell, while most neighbouring markets recorded increases. The move widened the discount to Hungary’s HUPX, despite sharp evening peaks that pushed hourly costs higher. SEEPEX settled at €137.92/MWh, down €12.30/MWh from the previous day.
Hungary’s HUPX rose by €7.60/MWh to €171.27/MWh. On the same day, Serbian electricity was priced at a €33.35/MWh discount to Hungary, with the gap widening by about €20/MWh in one session. Romania also moved lower, slipping by €2.60/MWh to €161.91/MWh.
Higher prices in Slovenia and Croatia widen regional spreads
Elsewhere in the region, prices strengthened after Serbia’s decline. Slovenia reached €188.30/MWh, up €17.50/MWh, while Croatia gained €9.30/MWh to €178.66/MWh. The divergence increased the potential value of supplying higher-priced markets from Serbia and the eastern Balkans.
The report linked that potential to hourly price differences, transmission capacity and the cost of securing cross-border access. Montenegro’s BELEN rose by €28.70/MWh to €142.87/MWh, reversing much of its recent weakness. Albania recorded the largest daily increase, climbing by €61/MWh to €158.90/MWh, while North Macedonia advanced by €20.80/MWh to €136.75/MWh.
Despite those gains, Montenegro, Albania and North Macedonia remained below Hungary’s level in the report period. Montenegro traded at a €28.40/MWh discount to HUPX, Albania at a €12.37/MWh discount and North Macedonia at a €34.52/MWh discount. Greece stayed the cheapest market at €120.52/MWh, although its daily average rose by €9.40/MWh.
Bulgaria rises as demand eases and renewables output changes
Bulgaria increased by €3.80/MWh to €138.63/MWh, leaving both Greece and Bulgaria substantially below Hungary and the western part of the region. Alongside the price moves, forecast supply conditions improved across Hungary and southeastern Europe. Forecast average demand eased to 29,086 MW, about 297 MW lower than the previous day.
The region’s net export position increased to 593 MW, from 248 MW. Forecast solar generation rose by 1,731 MW to 6,539 MW, more than offsetting a decline in wind output of 1,016 MW, bringing wind generation to 4,923 MW. The combined renewable change coincided with lower demand, with effects varying between markets and delivery hours.
