Greece increased net electricity exports by 52.83% in the week to November 1, while remaining the lowest-priced of seven major regional power markets. Its weekly average day-ahead price rose, but stayed below prices in Romania and Italy.

Serbia’s weekly average electricity price reached €286.55/MWh in late October, more than double its 2026 year-to-date average. The rise renewed focus on procurement and trading exposure across Southeast Europe.

Recurring evening electricity price peaks strengthened the commercial case for flexible generation, demand response and storage across Southeast Europe. The available weekly data do not establish project returns.

Low-carbon electricity from Western Balkan renewable projects will not automatically qualify for actual-emissions treatment under the EU’s CBAM. The Energy Community Secretariat modelled €8.9 million in opportunity costs for a 130 MW wind project over six months if it had to sell locally instead of accessing higher-priced EU markets.

Scheduled electricity exchanges between the Western Balkans Six and neighbouring EU markets fell 17.8% in January–September 2026, while regional day-ahead trading volumes rose 26.7% year on year in the third quarter. The Energy Community Secretariat’s assessment links the diverging trends to a market in which CBAM costs and conditions increasingly shape cross-border trade.
