Italy continued to act as the price ceiling for Southeast Europe in Week 25, with its day-ahead average reaching €127.69/MWh, the highest level among the covered markets. That premium was not accidental. Italy combined high consumption, weaker hydro, lower wind and a sharp increase in thermal generation, creating a strong import pull across the regional system.
The Italian market is structurally different from much of SEE because it can absorb large volumes at premium prices. In Week 25, Italy remained by far the largest net importer in the region, taking in 1.12 TWh of net electricity imports. This import dependency gives Italy a decisive role in regional spread formation. When Italian prices rise, neighbouring and corridor-linked markets gain stronger export incentives.
Italy’s thermal response was especially important. Total thermal generation jumped by 66.7%, with gas-fired production rising by more than 61% and coal generation almost quadrupling. This was not a normal baseload move; it was a system response to weaker renewable and hydro availability. Wind generation dropped by 42.5%, while hydro generation fell by 11.8%. In a high-demand week, that combination left the market dependent on flexible fossil dispatch and imports.
For SEE traders, Italy’s role is not limited to its own price. It influences the Adriatic, Balkan and Central European corridors by setting a premium destination for available power. Croatia, Slovenia, Greece and parts of the wider Balkan flow map are all indirectly affected when Italian import appetite strengthens. Even when physical flows are constrained, price expectations can adjust around Italy’s scarcity premium.
The investment message is equally clear. Italy’s scarcity periods reward flexibility, firm imports, storage-backed delivery and generation with evening availability. For SEE producers, this creates value in optionality. A megawatt that can reach Italian-linked price zones during tight hours has a different commercial profile from a megawatt trapped in a surplus midday market.
Italy’s Week 25 premium also underlines the regional importance of hydro and wind risk. A fall in Italian hydro and wind did not remain a domestic issue. It helped shape the wider SEE price environment, reinforced import flows and created a price ceiling that other markets used as a reference point.
