Southeast Europe is emerging as one of Europe’s lower-priced electricity regions, with growing renewable generation and battery deployment beginning to alter the regional price map. Bulgaria and Greece have been trading at around €185-193/MWh, below much of Central Europe, where prices have ranged around €225-270/MWh. Iberian markets have remained slightly lower at around €178-184/MWh, while Nordic markets are cheaper still.
The Balkan pricing position is supported by expanding wind and solar output in Greece. In Bulgaria, deployment of solar and battery storage is accelerating, adding to the region’s renewable capacity growth.
Renewables and storage changes in daytime-to-evening spreads
The shift toward more renewables and storage is commercially significant for a region that has historically faced tight generation margins and frequent electricity imports. Additional solar and storage could increasingly compress daytime prices. At the same time, it could widen spreads between solar hours and evening peaks.
This pattern would strengthen the commercial case for batteries, flexible generation, and cross-border trading.
Grid constraints become more important for new renewable connections
The next constraint is increasingly shifting from generation availability toward grid capacity. Balancing resources and the speed at which new renewable projects can connect are becoming more central to market outcomes.
