Italy again acted as the price ceiling for Southeast Europe during Week 25, with a day-ahead market average of €127.69/MWh, the highest among the analysed markets. The higher level reflected strong electricity demand alongside weaker renewable output and reduced hydro availability. This combination increased Italy’s reliance on both thermal generation and imports, keeping the country central to regional pricing.
Import role and link to regional price signals
Italy also remained the region’s largest net importer in Week 25, taking in approximately 1.12 TWh of net electricity imports. That dependence gave Italy a significant influence on how power market dynamics developed across interconnected systems. When Italian prices increased, neighbouring markets had stronger incentives to export electricity, reinforcing price signals across cross-border corridors.
Thermal generation rise amid weaker wind and hydro
A key development during the week was a sharp increase in Italy’s thermal generation. Total thermal output rose by 66.7%, driven by gas-fired generation up by more than 61%. Coal generation expanded almost fourfold as renewable availability weakened and hydro output declined.
Wind generation fell by 42.5%, while hydroelectric production dropped by 11.8%. With those declines, the system relied more heavily on flexible fossil-fuel generation and imported electricity to maintain supply security.
Trading corridors affected by Italian scarcity premium
For traders 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 along the Adriatic, Balkan and Central European corridors. Markets including Croatia, Slovenia and Greece were described as being influenced when Italian import demand strengthened.
The effect can persist even when transmission constraints limit physical flows, with market expectations adjusting to Italy’s scarcity premium.
Flexibility value for storage and dispatchable assets
Periods of elevated Italian prices were linked to stronger value for assets able to provide flexibility and firm delivery, including evening-hour availability. Battery storage, dispatchable generation, hydro flexibility and reliable import capacity were identified as becoming more valuable during such scarcity conditions.
For producers across Southeast Europe, access to Italian-linked pricing zones during tight periods was noted as potentially improving revenue compared with generation exposed only to oversupplied midday conditions.
Hydro and wind variability shaping regional outcomes
Week 25 also highlighted how variability in hydro and wind resources can carry through regional markets. The decline in Italian hydro and wind generation was described as contributing to stronger import demand beyond Italy itself. It also influenced cross-border trading patterns and helped shape electricity prices across Southeast Europe.
In that context, Italy’s scarcity premium was described as establishing an upper reference point for regional pricing. As interconnections deepen alongside continued renewable penetration growth, Italy’s role as a premium demand centre was expected to remain a factor affecting power flows, trading opportunities and investment strategies across the region.
