Greece’s gas sector is poised for substantial growth in 2025, driven by increased domestic consumption, a notable rise in exports, and enhanced utilization of infrastructure. According to data from DESFA, the country’s gas transmission system operator, natural gas consumption reached 70.16 TWh, reflecting a 6% year-on-year increase. Including cross-border flows, total system demand surged to 78.75 TWh, marking a 14% rise compared to the previous year.
A key highlight of this growth is the dramatic increase in gas exports, which nearly tripled year-on-year to 8.59 TWh. This surge reinforces Greece’s strategic position as a vital transit corridor for neighboring markets in southeastern Europe. To accommodate both domestic and regional demand, gas imports also saw a significant uptick, totaling 78.88 TWh—an increase of nearly 14% from 2024. The Sidirokastro entry point on the Bulgarian border was instrumental, accounting for almost half of these imports.
The role of liquefied natural gas (LNG) has become increasingly significant within this context. Despite a planned maintenance shutdown at the Revythoussa LNG terminal in late spring, deliveries remained robust. Additional volumes were introduced via the Nea Mesimvria point linked to the Trans Adriatic Pipeline (TAP) and through the Alexandroupoli floating storage and regasification unit (FSRU).
In terms of LNG activity, Revythoussa processed nearly 31 TWh across 49 tanker arrivals in 2025, representing a considerable increase over the previous year. The United States emerged as the dominant supplier, contributing over 80% of total LNG volumes, while smaller quantities were sourced from Nigeria, Egypt, Algeria, and Norway.
Moreover, small-scale LNG distribution has expanded rapidly. Truck loading operations at Revythoussa more than doubled during the year, with over 700 trucks supplied to meet rising demand from industrial consumers and remote regions seeking flexible gas solutions.
Electricity generation continues to be the largest consumer of natural gas in Greece, accounting for just over 70% of domestic demand. While consumption through distribution networks increased, usage by industrial users and compressed natural gas (CNG) stations declined compared to the previous year.
The data for 2025 indicate a gas system operating at significantly higher intensity across various segments. The rise in exports, stronger LNG flows, and expanding small-scale services underscore Greece’s evolving role as a regional energy hub. This trend highlights the strategic importance of DESFA’s infrastructure in facilitating supply diversification and enhancing market flexibility.
