In 2025, Greece’s natural gas market is experiencing a notable expansion, driven by increased domestic consumption, a substantial rise in exports, and enhanced utilization of key infrastructure. According to data from DESFA, the country’s gas transmission system operator, this year marks a pivotal moment for Greece as it solidifies its role within the regional energy landscape.
The total gas consumption within Greece reached 70.16 TWh, reflecting a 6% increase year on year. When factoring in cross-border flows, total system demand surged to 78.75 TWh, translating to a 14% increase compared to 2024. This uptick underscores the growing significance of natural gas in the national energy mix.
A remarkable highlight of 2025 was the dramatic increase in gas exports. Outbound flows nearly tripled, reaching 8.59 TWh, reinforcing Greece’s strategic position as a vital transit corridor for neighboring southeastern European markets. To satisfy both domestic and regional demand, gas imports also saw a significant rise, totaling 78.88 TWh, which is nearly 14% higher than the previous year. Notably, the Sidirokastro entry point, located on the Bulgarian border, accounted for almost half of these imports.
The role of liquefied natural gas (LNG) has become increasingly critical in this growth trajectory. Deliveries through the Revythoussa LNG terminal saw robust increases despite scheduled maintenance in late spring. Additional volumes were introduced via the Nea Mesimvria point, associated with the Trans Adriatic Pipeline (TAP), as well as through the Alexandroupoli floating storage and regasification unit (FSRU).
LNG activity intensified significantly throughout the year, with Revythoussa handling nearly 31 TWh across 49 tanker arrivals, marking a sharp increase from 2024 levels. The supply landscape was dominated by the United States, which contributed over 80% of total LNG volumes, complemented by smaller shipments from Nigeria, Egypt, Algeria, and Norway.
The expansion of small-scale LNG distribution was also noteworthy. Truck loading operations at Revythoussa more than doubled, with over 700 trucks serviced during the year. This growth reflects an increasing demand from industrial consumers and remote regions seeking flexible gas solutions.
In terms of end-use applications, electricity generation remained the predominant consumer of natural gas, accounting for just over 70% of domestic demand and continuing its upward trend. While consumption through distribution networks increased, usage by industrial users and compressed natural gas (CNG) stations declined compared to previous years.
The data for 2025 indicates a gas system operating at significantly higher intensity across various segments. The combination of rising exports, stronger LNG flows, and expanding small-scale services emphasizes Greece’s evolving role as a regional energy hub while highlighting DESFA’s strategic infrastructure importance in promoting supply diversification and market flexibility.
