Cross-border electricity trading became one of the strongest market themes in Southeast Europe during Week 22. Total regional exchanges increased 8.4% week-on-week to 1,117 GWh, with Greece, Bulgaria and Türkiye expanding exports while Italy, Romania and Croatia increased imports. The flows were not just moving power from surplus to deficit zones. They were revealing where market value is now being created: in spreads, interconnector access and timing. As reported by Electricity.trade, SEE power trading is shifting from a volume business into a spread-capture business.
The strongest pull came from Italy. Net imports rose 28.3% to more than 1.1 TWh, while the Italian price climbed to €123.58/MWh. That combination created a premium destination for regional electricity. Exporters and transit-positioned traders had clear incentive to move power toward the Italian market where capacity allowed. Italy’s import demand confirmed the commercial importance of interconnectors into high-price zones.
Greece moved in the opposite direction, strengthening net exports by 35.7% to 241 GWh while maintaining a lower weekly price of €86.77/MWh. Bulgaria also improved its net export position sharply, from 6 GWh to 61 GWh, helped by a solar-driven supply boost and an 11.3% price decline. Türkiye nearly tripled exports to 95 GWh after prices collapsed to €4.03/MWh. These export positions show how low-cost or surplus markets can monetise generation through cross-border channels, but only within the limits of available capacity.
The import side was equally revealing. Romania increased net imports by 27.1%, Croatia by 36.5%, and Italy by 28.3%. Hungary reduced its net import position by 18.7%, while Serbia’s imports stayed broadly stable despite a 30.1% price surge. That Serbian case is especially important because it shows that imports do not automatically rise when prices rise. Congestion, availability, scheduling and commercial positioning can all prevent full price convergence.
For traders, this is the central lesson. SEE is becoming a market where forecasting national balances is not enough. The value lies in understanding interconnector capacity, auction prices, hourly spreads, renewable output, hydro availability, thermal marginality and balancing risk. A trader who sees Bulgaria’s solar surplus, Greece’s export position and Italy’s premium can identify opportunity only if the route is physically and commercially accessible.
For investors, stronger cross-border activity supports the case for flexible assets. Batteries, pumped storage, flexible hydro, demand response and dispatchable gas all gain value when spreads widen and flows intensify. Renewable projects also benefit when export capacity reduces curtailment and improves capture prices.
Week 22’s 1,117 GWh of cross-border exchanges showed that SEE market integration is real, but incomplete. That incompleteness is precisely where trading value sits. Price spreads are no longer noise around the market. They are becoming the market.
