Energy Community monitoring for the second quarter indicates that Western Balkan contracting parties became net importers of EU electricity overall. Some exports toward EU markets continued on selected corridors. The shift points to changes in how cross-border electricity economics are operating ahead of the autumn trading period.
As the EU’s Carbon Border Adjustment Mechanism moves from planning into implementation, traders are expected to compare more than wholesale price spreads. The carbon-adjusted value of electricity crossing from the Western Balkans into the EU is expected to factor into border pricing during autumn.
Quarterly monitoring shows net import position and corridor exports
The second-quarter data show Western Balkan contracting parties taking a net import position for EU electricity. At the same time, exports to EU markets were reported as continuing on selected corridors. This combination reflects uneven flows rather than a uniform shift across all routes.
The monitoring findings suggest that traditional arbitrage based on cross-market price differences is already being disrupted. Before CBAM, a Serbian, Bosnian or Montenegrin exporter could focus primarily on price gaps between its domestic market and Hungary, Croatia or Italy.
CBAM adds embedded emissions costs to EU import decisions
Under the definitive CBAM regime, EU importers must account for embedded carbon emissions associated with imported electricity. This requirement applies alongside existing market price considerations at the border. The change affects how exporters and traders assess competitiveness into EU destinations.
The embedded emissions requirement creates a structural disadvantage for lignite-heavy electricity unless actual emissions can be demonstrated and verified at a materially lower level than the applicable default. The effect is expected to become more visible during autumn scarcity events when market conditions tighten.
Wholesale spreads can change after CBAM liability is included
A €20-30/MWh wholesale spread may appear attractive in isolation, but it can be reduced once CBAM liability tied to high-carbon generation is included. Renewable and hydro electricity are expected to retain stronger export economics in principle, but practical compliance issues have been flagged.
The Energy Community warned that renewable producers face difficulties proving compliance with requirements related to actual emissions. European Commission guidance issued in August reinforces monitoring expectations, including contractual traceability and verification steps.
Two values emerge for Western Balkan electricity flows
The commercial consequence described in the monitoring and policy context is the emergence of two parallel values for Western Balkan electricity. One value corresponds to the ordinary domestic or regional wholesale price. The other reflects a CBAM-adjusted EU netback after carbon and evidence costs.
This dual pricing framework could influence how EPS, EPCG, ERS, EPBiH and independent producers allocate generation among domestic buyers, EU exports and other non-EU markets. For autumn traders, the key border spread is described as no longer being simply SEEPEX-HUPX or Montenegro-Italy.
Instead, the relevant comparison is framed as the wholesale spread after carbon exposure and verification risk are priced in for electricity moving from the Western Balkans into the EU.
