During Week 25, Italy acted as the price ceiling for Southeast Europe in day-ahead power trading, with an average market price of €127.69/MWh, the highest among the analysed markets. The premium reflected strong electricity demand alongside weaker renewable output and reduced hydro availability. These conditions increased Italy’s requirements for both thermal generation and imports, sustaining its influence on regional pricing.
Italy also remained the region’s largest net importer in Week 25, taking in approximately 1.12 TWh of net electricity imports. This import dependence supported Italy’s role in shaping power market dynamics across interconnected systems. When Italian prices increase, neighbouring markets face stronger incentives to export electricity, reinforcing price signals along cross-border corridors.
Thermal generation rise linked to weaker wind and hydro
A notable development in Italy during the week was a sharp increase in thermal output. Total thermal generation rose by 66.7%, with gas-fired production increasing by more than 61%. Coal generation expanded almost fourfold as the system adjusted to lower renewable availability and reduced hydro output.
Wind generation fell by 42.5%, while hydroelectric production declined by 11.8%. With renewables and hydro contributing less, Italy relied more heavily on flexible fossil-fuel generation and imported electricity to maintain supply security. The shift supported higher levels of thermal dispatch during the period.
Cross-border trading effects across Adriatic and Balkan corridors
For traders operating across Southeast Europe, Italy’s impact extends beyond its domestic market. The country functions as a premium destination for available electricity, affecting trading opportunities and price formation across the Adriatic, Balkan and Central European corridors. Croatia, Slovenia and Greece are among the markets influenced when Italian import demand strengthens.
Even where transmission constraints limit physical flows, market expectations can still adjust to reflect Italy’s scarcity premium. This mechanism can affect how participants price power across interconnected bidding zones during periods of tighter supply conditions. The resulting changes are reflected in regional day-ahead outcomes.
Flexibility value and hydro-wind variability in Week 25
The investment implications highlighted during Week 25 focused on assets able to respond to scarcity conditions. Elevated Italian prices tended to reward resources providing flexibility, firm delivery and evening-hour availability. Battery storage, dispatchable generation, hydro flexibility and reliable import capacity were identified as increasingly valuable during these periods.
The week also underscored how hydro and wind resource variability can influence regional outcomes. The decline in Italian hydro and wind generation did not remain confined to domestic balancing needs; it contributed to stronger import demand and affected cross-border trading patterns. These factors helped shape electricity prices throughout Southeast Europe during the period.
Italy’s scarcity premium established an upper reference point for regional pricing during Week 25. As interconnections deepen and renewable penetration continues to grow, Italy’s role as a premium demand centre is expected to remain a key factor for power flows, trading opportunities and investment strategies across Southeast Europe.
