In Week 22, covering 25–31 May 2026, Italy recorded the highest weekly average day-ahead electricity price in the SEE-linked group at €123.58/MWh, up 6.3% week-on-week. The same period saw a 28.3% increase in net electricity imports to more than 1.1 TWh. Italy cleared at a level above Greece, Bulgaria, Romania, Croatia, Hungary and Serbia. As reported by Electricity.trade, the Italian premium was used to indicate that interconnector value in Southeast Europe is increasingly shaped by scarcity spreads rather than energy volumes.
Wind decline tightens Italy’s supply-demand balance
The Italian system tightened as wind generation weakened while demand and thermal output increased. Regional wind output fell by 30.0%, with Italy accounting for a large share of the decline as wind generation dropped by 49.9%. Over the same week, Italian electricity demand rose by 10.8%, adding 505 GWh week-on-week. The change in conditions increased reliance on dispatchable generation.
Thermal generation in Italy increased alongside the higher demand and weaker wind output. Thermal production rose by 32.6%, while gas-fired generation increased by 25.3%. The figures indicate that the market relied not only on cross-border supply but also on higher domestic gas-fired output during the week.
Cross-border flows and interconnector value in SEE
Italy’s pricing level fed into how neighbouring markets participated in regional scarcity conditions during Week 22. When Italy cleared above €120/MWh, markets connected to it were described as becoming part of a regional scarcity trade. Export routes into Italy were associated with higher value under those conditions.
Traders with access to interconnected positions involving Slovenia, Croatia, and Greece could monetise spreads when interconnection capacity was available. At the same time, the pattern highlighted that import dependence does not automatically prevent price increases when domestic marginal generation remains linked to gas and wind availability falls sharply.
Implications for generators, industry and storage
For generators, Italy remained one of the strongest revenue markets within the regional system during the period described. Industrial buyers faced exposure to gas-price risk in the same market context. For storage investors, the Italian setup continued to support an arbitrage case where solar-led midday weakness can coincide with evening scarcity when wind underperforms.
The Week 22 data linked cross-border flows with commercial outcomes beyond balancing needs. Price separation, import dependency and renewable intermittency were cited as factors defining how capacity value was reflected in trading during the week.
€123.58/MWh day-ahead pricing in Italy, net imports of more than 1.1 TWh, and rising gas-fired generation were presented as the clearest indicators of where SEE trading margins were being created across the period covered.
