On April 13, electricity prices across Southeast Europe and Hungary experienced a notable increase, driven by heightened demand, warmer temperatures, and evolving cross-border trading dynamics. However, the price growth was not uniform; Serbia’s SEEPEX exchange emerged as a significant outlier, offering the lowest prices in the region.
Day-ahead baseload prices surged across various power exchanges. Hungary’s HUPX recorded a price of 97.98 €/MWh, while Romania’s OPCOM settled at 94.91 €/MWh. Bulgaria’s IBEX reached 91.75 €/MWh, Greece’s HENEX at 90.06 €/MWh, Croatia’s CROPEX at 90.11 €/MWh, and Slovenia’s BSP at 85.75 €/MWh. In stark contrast, Serbia’s SEEPEX cleared at just 77.34 €/MWh, reinforcing its position as the most competitively priced market in Southeast Europe. Montenegro’s BELEN also aligned with regional trends at 91.26 €/MWh.
This divergence illustrates localized supply conditions and highlights Serbia’s role as a pricing outlier in the region. The price spread between Hungary and Serbia expanded to over 20 €/MWh, creating opportunities for arbitrage among cross-border traders and enhancing SEEPEX’s attractiveness within the regional market.
Western European markets maintained higher pricing structures, with Germany trading at 127.30 €/MWh, Austria at 114.33 €/MWh, and Italy at 141.86 €/MWh. This persistent premium of core European markets over Southeast Europe continues to influence interconnector flows and facilitates exports from Central and Southeastern Europe to higher-priced markets when transmission capacity allows.
Demand Growth and Renewable Energy Impact Market Dynamics
The electricity consumption in the SEE and Hungarian regions rose to 27,134 MW, reflecting an increase of 2,247 MW from the previous day due to stronger economic activity and seasonal demand patterns. This uptick coincided with milder temperatures and improved industrial load factors, exerting upward pressure on prices.
Despite the rise in demand, generation dynamics were significantly influenced by renewable output. Solar generation saw a substantial increase, playing a crucial role in the regional energy mix, while hydroelectric power remained vital for system flexibility. The generation breakdown indicated that hydro contributed 26%, nuclear 24%, solar 19%, coal 16%, and gas 12%, with wind providing a smaller share.
Total regional generation reached 24,767 MW, with moderate imports indicating balanced system conditions. Notably, solar output increased by more than 1 GW day-on-day, underscoring the growing impact of renewables on intraday pricing patterns and market volatility.
Cross-Border Flows Shape Regional Price Formation
The ongoing cross-border electricity flows continued to influence price formation within the region. Hungary remained a net importer while Romania, Bulgaria, and Greece contributed to regional supply stability. Serbia also depended on imports despite its lower price level.
The spread between Hungarian and German prices stood at -29.32 €/MWh, indicating significantly lower prices in Hungary compared to Germany, which encouraged electricity flows from west to east. Such spreads highlight the importance of market coupling and interconnector capacity in aligning regional price signals with broader European markets.
Commercial flow data indicated robust trading activity across borders, particularly along corridors connecting Hungary, Romania, Bulgaria, Croatia, and Greece. These trading flows reinforce Southeast Europe’s strategic position as a bridge between Central Europe and Mediterranean energy markets.
Intraday Volatility Driven by Solar Expansion
An analysis of hourly price curves revealed significant volatility primarily attributed to solar generation fluctuations. Midday hours experienced reduced prices due to increased photovoltaic output, while spikes in evening demand led to higher prices across major exchanges such as HUPX, OPCOM, BSP, and HENEX.
This pattern reflects the increasing structural influence of renewable energy within the region’s electricity markets. As solar capacity expands further, market participants are increasingly relying on flexible assets such as battery storage and gas-fired generation alongside cross-border trading to manage intraday imbalances effectively.
Forward Markets Indicate Stability Amid Spot Price Rebound
The forward markets signaled relative stability despite recent spot price increases. Hungarian power futures were assessed at 108 €/MWh for Week 16, 102 €/MWh for Week 17, 91 €/MWh for May 2026, and 108 €/MWh for Cal-2026.
The fuel markets remained relatively subdued; the Austrian CEGH gas benchmark traded at 46.23 €/MWh, while EU carbon allowances (EUA) were priced at 72.84 €/t. These levels suggest moderate cost pressures for thermal generation and indicate that recent spot price increases are more influenced by short-term fundamentals than by structural constraints.
The trends in coal futures and gas prices showed downward movements, further reinforcing expectations of stable or slightly softer electricity prices in the medium term as renewable capacities continue to expand across the region.
Market Outlook: Key Trends Ahead
The developments observed on April 13 reflect a market characterized by seasonal demand recovery alongside increasing renewable penetration and persistent regional price disparities. Key trends influencing the SEE and Hungarian electricity markets include:
The ongoing rise in solar generation continues to reshape intraday price dynamics while dampening midday prices.
The stability of forward curves indicates balanced supply-demand expectations with limited bullish pressure from fuel markets.
Persistent pricing disparities between Western Europe and Southeast Europe support cross-border trading opportunities.
The role of Serbia as a low-cost electricity hub provides competitive advantages for regional traders.
In conclusion, traders will closely monitor renewable output trends, temperature forecasts, and interconnector availability moving forward. Special attention will be given to the Hungary–Germany spread along with SEEPEX pricing dynamics as critical indicators of regional liquidity and market direction.
The integration of Southeast Europe into the broader European power market continues to deepen, emphasizing its growing strategic importance in continental energy trading and system balancing.
