In 2025, the Greek electricity market experienced a moderate rise in prices, with the average in the day-ahead market reaching 103.6 euros/MWh. This increase aligns with a broader trend of rising prices across Europe, yet Greece maintained a competitive edge compared to its regional counterparts, notably Bulgaria and Italy.
Bulgaria’s average price was recorded at 106.9 euros/MWh, while Italy topped the list with 115.03 euros/MWh. Greece’s year-on-year price increase of 2.7% is modest when juxtaposed with Bulgaria’s 4.24% and Italy’s 6% increases, indicating a relatively stable pricing environment.
The year saw significant fluctuations in monthly prices, with February emerging as the peak month at an average of 154 euros/MWh. Conversely, August registered the lowest prices at 73 euros/MWh. Notably, on May 1, the market saw an unprecedented hourly price drop to -50 euros/MWh, reflecting the volatility that can occur within the market.
Electricity demand remained stable throughout the year, while renewable energy sources contributed to an 8% increase in generation volumes. This growth underscores the expanding role of renewables in Greece’s energy landscape, aligning with broader European energy policy objectives aimed at increasing sustainability and reducing carbon footprints.
Cross-border electricity flows exhibited notable changes as well. Imports decreased significantly by 2,833 GWh, marking a decline of 36.8%. In contrast, exports experienced a slight uptick of 106 MWh, culminating in net electricity exports of 2,732 GWh for the year. The peak trading activity occurred on July 25, with total market activity reaching 254 GWh.
The market structure remains dominated by Public Power Corporation (PPC), which accounted for over half of the total supply at 50.08%. This dominance illustrates PPC’s pivotal role in shaping Greece’s electricity landscape amidst evolving market dynamics.
