The regional power market moved into a more clearly bifurcated pricing pattern on 19 June, with northern and central European systems remaining structurally tight, while Southeastern Europe benefited from stronger renewable generation, especially solar and wind. This created a sharp divergence between Hungary and southern Balkan markets.
Spot market overview
Hungary remained the highest-priced market in the region at €115.75/MWh, despite a notable day-on-day decline of almost €18/MWh. Serbia moved in the opposite direction, standing out as the only major market with a sharp increase, as SEEPEX reached €111.05/MWh, up nearly €32/MWh. Romania settled at €105.99/MWh, Slovenia at €105.52/MWh, Croatia at €103.98/MWh, while Bulgaria and Greece remained significantly lower at €81.88/MWh and €76.84/MWh respectively, reflecting strong renewable suppression in southern markets.
The pricing structure indicates that renewable generation increasingly dictates southern price levels, while congestion and localized balancing needs continue to support premiums in Serbia and Hungary.
Renewable generation driving market fundamentals
Regional electricity consumption increased to approximately 30.2 GW, while total generation rose even faster to 30.6 GW, temporarily turning the region into a modest net exporter. Wind output surged by more than 1.1 GW day-on-day, while solar increased by over 540 MW, reinforcing the growing dominance of weather-driven generation in daily price formation.
The generation mix was broadly balanced across technologies:
Solar: 21%
Hydro: 20%
Nuclear: 17%
Coal: 15%
Gas: 14%
Wind: 9%
Renewables therefore accounted for roughly half of total regional generation, increasingly shaping intraday volatility and price dispersion.
Hungary remains regional price setter
Hungary continues to function as the key price benchmark for Southeast Europe, with the Hungary–Germany spread widening to €7.57/MWh, reversing earlier negative differentials. Imports from Austria and Slovakia also shifted back into positive territory, highlighting renewed dependency on Western European flows during peak hours.
Forward markets remain strongly bullish:
Week 26 Hungary Baseload: €137.50/MWh
Week 27: €128.50/MWh
July 2026: €119.00/MWh
Calendar 2026: €110.50/MWh
These elevated forward prices suggest traders are still pricing in tight summer fundamentals and evening scarcity risk.
Serbia emerges as regional outlier
Serbia showed the most unusual market behavior, with SEEPEX rising to €111/MWh while most regional markets declined. It traded above Croatia, Bulgaria, Greece and Montenegro despite generally favorable renewable conditions across the region.
This reflects a growing structural pattern in Serbia:
Reduced flexibility due to slower renewable grid integration
Higher balancing costs during peak periods
Increased dependence on imports in specific hours
Limited new merchant renewable capacity
As a result, Serbia is increasingly exhibiting localized scarcity pricing dynamics, even when regional fundamentals appear oversupplied.
Cross-border flows
Commercial flow patterns confirm continued strong West-to-East and North-to-South electricity movements across the region.
Key average flows included:
Hungary → Austria: ~705 MW
Slovenia → Italy: ~692 MW
Hungary → Slovakia: ~601 MW
Romania → Hungary: ~420 MW
The data reinforces Italy’s role as a premium sink market, attracting exports from neighboring systems whenever transmission capacity is available.
Fuel markets support lower power prices
Fundamental fuel indicators remained broadly bearish for electricity prices.
Gas markets softened further:
CEGH Austrian Gas: €42.21/MWh
Greece gas benchmark: €40.07/MWh
Coal also declined:
API2 July 2026: €110.5/t
Q3 2026: €109.5/t
Carbon remained stable:
EUA Dec-2026: €80.01/t
Overall, weaker fuel inputs continue to provide a downward pressure on marginal power generation costs.
Storage and flexibility become central theme
A series of developments highlight the accelerating shift toward flexibility-driven market structure.
Bulgaria commissioned a 602 MWh battery storage facility in Burgas, while Romania added a hybrid 26 MW solar + 10.67 MWh battery project. Greece also reported more than 4.5 GW of data center connection requests, signaling future demand growth.
Together, these trends confirm that:
Storage is becoming a trading and arbitrage asset
Flexibility is the new bottleneck of the system
Data centers are emerging as a structural demand driver
Trading outlook
The market continues to show a classic summer volatility pattern, with strong solar output suppressing midday prices and steep evening ramps driving peak pricing.
Hungary remains the regional benchmark, but Serbia is increasingly behaving as a separate pricing zone driven by local balancing constraints rather than regional fundamentals.
Looking ahead into late June and early July, the combination of strong renewables, weaker gas prices, stable carbon costs and moderate temperatures points to a generally bearish average price outlook. However, evening spreads and intraday volatility remain highly attractive, especially for storage operators and flexible assets across Hungary, Serbia and the Italian export corridor.
