Greece recorded 6.1 TWh of net power exports in the first eight months of 2026, reversing regional electricity flows. Higher prices in neighbouring Southeast European markets created stronger opportunities for Greek generators and traders. Electricity exports totalled 9.24 TWh from January to August, a 70% increase year on year, according to transmission system operator ADMIE.
Imports declined by 27% to 3.14 TWh over the same period. The fall in imports widened the gap between electricity entering and leaving the Greek market. The figures reflect a significant shift in Southeast Europe’s electricity trading structure.
Changing regional power flows
Greece has historically relied more on imports when domestic supply was tight. As renewable generation expands, the country is increasingly supplying neighbouring power systems, while electricity prices to the north remain comparatively high. Disruptions in regional markets and tight generation conditions elsewhere in Southeast Europe have further improved the competitiveness of Greek exports.
These conditions have created greater opportunities for electricity to flow to Bulgaria, North Macedonia, Albania and other interconnected markets. Higher exports have also supported Greece’s external trade balance. Cross-border power trading is becoming a more significant part of the domestic energy sector.
Greece’s growing export role
The January-August results establish Greece as one of Southeast Europe’s increasingly important electricity-export hubs. Northbound flows from Greece are also playing a stronger role in balancing tighter Balkan markets.
