Electricity.Trade’s May 2026 analysis shows Greece occupying a distinctive position in the regional trading map. It was the lowest-priced interconnected European SEE market, with an average spot price of €88.98/MWh, only 0.29% higher than in April and 8.59% higher year on year. Unlike Türkiye, Greece remained within the EU-linked regional pricing range, but still cleared below Bulgaria, Serbia, Croatia, Hungary, Romania and Italy. That lower price did not reflect weak market relevance. On the contrary, Greece became a large exporter during the month.
Greece registered net electricity exports of 874.20 GWh in May. It imported from Albania and Türkiye, exported to North Macedonia and Bulgaria, and recorded no trade with Italy. The most important flow was with Bulgaria, where Greek exports reached 666.23 GWh. This made Greece one of the region’s clearest examples of a market where strong domestic renewable and hydro output translated directly into cross-border trading relevance.
The generation mix was decisive. Greece’s May electricity mix consisted of 57.19% renewables, 28.11% gas, 8.42% hydro and 4.29% coal/lignite. Renewable generation rose by 15.88%, while hydro generation increased by 40.80% to 408.78 GWh, supported by improved precipitation. At the same time, demand rose by 2.44%, meaning Greece’s export position was not simply the result of weak domestic consumption. The system produced enough low-marginal-cost electricity to cover stronger demand and still export significant volumes.
For traders, Greece’s May profile shows the value of renewable-heavy systems when hydro also supports dispatch. Greece did not need the highest regional price to become one of the most relevant trading markets. Its lower average price created export pressure into neighbouring markets, especially Bulgaria, while gas remained a material but not dominant part of the mix. This is precisely the kind of market structure that can produce strong intraday and cross-border trading signals: solar and wind depress certain hours, hydro provides dispatch support, and gas remains available for residual balancing.
Electricity.Trade should frame Greece as a market where the energy transition is already visible in trade flows. The May result shows that renewable penetration is no longer only a domestic decarbonisation metric. It is a trading variable. When Greece has strong RES and hydro conditions, it can become a price-setting exporter into the Balkans, changing the regional flow map and creating opportunities for traders positioned around Greek-Bulgarian and Greek-North Macedonian corridors.
