Western Balkan Power Trade Shifts Away From EU
Regional day-ahead volumes climbed in Q3 2026 while scheduled exchanges with the EU fell, according to an Energy Community Secretariat analysis.
Updated on Nov. 4, 2026 in International Trade
Day-ahead traded volumes on four Western Balkans power exchanges reached about 2.97 TWh in Q3 2026, up 26.7% from Q3 2025. Gross scheduled exchange between the WB6 and the EU fell 14.3% over the same period, the Energy Community Secretariat reported.
Why it matters
The shift reflects changing regional power flows as the EU's Carbon Border Adjustment Mechanism, which entered into force on January 1, 2026, reshapes electricity trade. The Secretariat notes that CBAM is only one of several factors, alongside generation, demand, cross-border capacity and regional market conditions.
The Energy Community Secretariat's analysis covers four Western Balkans day-ahead exchanges, with 2.97 TWh traded in Q3 2026, up 26.7% year over year. Gross WB6-EU scheduled exchange fell 17.8% over January through September 2026 compared with the same period of 2025, and the report does not fully separate CBAM's effect from other drivers.
The players
Energy Community Secretariat
The Vienna-based body that administers the Energy Community treaty linking the EU with Southeast European and neighbouring energy markets, and which published the CBAM impact analysis.
The details
Scheduled exports from Montenegro to Italy rose by around 80%, while exports from Serbia to Hungary declined 21.6%. Serbia showed an average 30-day correlation of 0.87 with the Hungarian day-ahead price in Q3 2026, and in 53.9% of hours price spreads across eight WB6-EU pairs exceeded EUR 20/MWh.
Timeline
January 1, 2026: Cross-border carbon tax (CBAM) entered into force.
Q3 2026: Day-ahead volumes rose while scheduled EU exchanges fell year over year.
September 2026: Hourly price spreads above EUR 20/MWh reached 63% of hours.
November 4, 2026: The Energy Community Secretariat published its third CBAM report.
Market Dynamics
The regional trade shift is being tracked against the EU Carbon Border Adjustment Mechanism Regulation, which took effect in 2026 and began imposing carbon costs on imported goods. This third Energy Community monitoring update extends the pattern of earlier reports by measuring how far electricity trade and price convergence have moved since the regime started.
Traders and utilities active in Balkan and Hungarian power markets face wider and more frequent price spreads, with spreads above EUR 20/MWh in more than half of Q3 hours. Firms whose electricity costs depend on regional imports should track how these spreads and CBAM-linked pricing feed into contract and hedging decisions.
The takeaway
Regional power prices are moving more closely with some EU neighbours even as direct scheduled trade with the bloc shrinks, so price exposure may matter more than volume when assessing Balkan energy risk. Market participants should watch hourly spreads rather than trade totals alone.
