Italy remained the premium electricity market in Southeast Europe during Week 23, reinforcing its role as a high-price anchor for regional trading strategies. The Italian weekly day-ahead average rose 3.7% to €128.09/MWh, well above neighbouring SEE markets and far above Türkiye’s structurally low price level.
The spread was significant. Greece averaged €89.25/MWh, Serbia €99.63/MWh, Croatia €99.29/MWh, Bulgaria€100.83/MWh, Romania €102.23/MWh and Hungary €103.15/MWh. Italy therefore traded at a premium of nearly €39/MWh to Greece and around €27–29/MWh to several Balkan markets clustered around the €100/MWh level.
This premium matters because Italy remains a major destination for regional power flows where interconnector capacity allows. Even though Italy reduced net imports by 14.1% during the week, it still remained the largest net importer in the SEE region, with 950.91 GWh of net imports. That combination — lower imports but still the highest price — shows how structurally tight the Italian market remains.
For Balkan generators, Italy’s premium creates optionality. Hydro, lignite, gas, wind and solar assets located in neighbouring markets can capture value when export routes are available and congestion does not block flows. For traders, the Italy-Balkans spread creates opportunities in scheduling, hedging, transmission rights and congestion management.
The spread is not always fully tradable. Interconnector constraints, scheduled flow limits, internal bottlenecks and market coupling conditions decide how much price convergence can occur. The Week 23 flow map shows active regional exchanges, but persistent price differences prove that physical and commercial constraints still matter.
Italy’s price structure is also tied to fuel risk. The country remains exposed to gas-linked marginal pricing, even in weeks when gas-fired generation falls. With TTF prices near €49/MWh, Italian power retains a fuel-risk premium that can widen against markets with stronger hydro, lignite or cheaper domestic supply.
For Greece, Croatia, Slovenia and the Western Balkans, Italy’s high-price signal is strategically important. It can improve the economics of flexible generation and cross-border trading, but it also exposes import-dependent consumers to regional price volatility. The same spread that benefits exporters can raise costs for industrial offtakers if domestic markets converge upward.
Italy’s premium also strengthens the investment case for interconnectors and grid reinforcement. Where price spreads persist, transmission capacity has economic value. Projects that increase transfer capability between lower-cost Balkan zones and higher-priced Italian or Central European markets can unlock trading gains, improve security of supply and reduce price fragmentation.
Week 23 showed that Italy continues to function as the region’s high-price sink. For Balkan power markets, that keeps export optionality alive. For investors, it reinforces a simple point: generation value in SEE is increasingly linked not only to output, but to location, interconnector access and the ability to monetise spreads.
