Domestic gas consumption rose in July (5.6 TWh, +11.6) due to increased use in electricity generation. Cumulatively, consumption for the first 7 months of the year reached 40 TWh. LNG ranked first in imports (24.9 TWh), reaching a historic high. Gas exports (10.2 TWh) hit a 3-year high, with 83% going via Sidirokastro. Compared to the other EU-27 member states during the first half of 2026, Greece ranked 6th, reducing its gas consumption by 0.9% compared to 2025, while the EU-27 average was +1.12%.
This analysis concerns domestic consumption, imports, and exports of fossil gas. It is based on historical data from DESFA on Validated Daily Natural Gas Deliveries / Off-takes (until December 2025), as well as the latest available data of N.G. Nominations / Allocations from DESFA’s New Commercial Information System (July 2026). It also uses the latest monthly data published by Eurostat on imports of liquefied natural gas (LNG) imported from Russia (June 2026).
Consumption
July
In July 2026, domestic gas consumption rose by 11.6% compared to June, reaching 5.6 TWh. However, it was 12.2% lower than consumption in July of the previous year.
The power generation sector, at 4.55 TWh, accounted for 81.1% of the total, while it increased by 16.9% compared to June. Compared to July 2025, when gas use in electricity generation reached a four-year high, the electricity sector saw a 12% decline this month.
Next was the grids sector, with consumption of 675 GWh (12% of the total), remaining close to June’s levels (+1.6%). Compared to July of last year, gas consumption in the grids sector increased by 9.7%, reaching the highest level for the month of July in the last fifteen years.
Industry came in last, with consumption of 382 GWh—a three-year low. Its share of total domestic consumption was 6.8%, while compared to the previous month, it fell by 18.2%, continuing the downward trend that began in March. Compared to last year, the industry’s gas consumption fell to two-thirds of the level recorded in July 2025.
First seven months of the year
Cumulatively, over the first seven months of the year, total domestic gas consumption was 40 TWh, down 2.4% compared to 2025 but higher than consumption levels in the previous three years (2022, 2023, 2024).
Although the electricity sector declined by 5.1% compared to last year, it remained the top consumer at 27 TWh and recorded the second-highest consumption for this period of the year since 2025.
Networks were the second-largest sector for gas use, with 8.8 TWh, marking the second-highest consumption since 2022. Compared to last year, consumption increased by 5.4%.
Industry ranked last with 4.3 TWh and the 2nd-lowest consumption for this time of year in the last 4 years, following 2025. Compared to last year, there was a slight increase of 0.4%.
As for the breakdown of domestic consumption for the first seven months of the year across the three sectors, electricity accounted for 67.4%, networks for 21.9%, and industry for 10.7%.
Exports
Total gas exports in July 2026 amounted to 1.5 TWh, double the exports in June. The largest share was exported via Sidirokastro (1.07 TWh), while smaller, comparable volumes were exported via the Nea Mesimvria gate (0.2 TWh) and via the Komotini-IGB gate (0.18 TWh).
Cumulatively, over the first seven months of the year, gas exports reached 10.2 TWh, marking a three-year high. The majority of exports (82.8%) passed through Sidirokastro, totaling 8.4 TWh, followed by the Komotini-IGB gate, with exports totaling 1.2 TWh. Finally, 0.55 TWh was exported via the Nea Mesimvria gate during the first seven months of the year.
Imports
July
Total net imports into the National Transmission System—which covered domestic demand exclusively—amounted to 5.8 TWh in July, an increase of 15.7% compared to June, due to the resumption of operations at the Amfitriti gateway and an increase in imports via Sidirokastro, which more than offset the decrease in imports via Agia Triada.
The Revythousa FSRU (Agia Triada gate) ranked first in imports for July, with LNG imports reaching 2.28 TWh, despite a significant 29% decrease compared to June. The Alexandroupolis FSRU (Amfitriti gate), which returned to normal operation following a three-month maintenance period, recorded LNG imports of 0.54 TWh for July.
In second place for imports after LNG was the Sidirokastro gate (which is the main entry point for Russian gas), with net imports reaching 2.25 TWh, more than double the volume of June’s imports and very close to the volume of LNG imports through the Agia Triada gate.
In last place were imports via the Nea Mesimvria gate (through which Azerbaijani gas is imported via the TAP pipeline) at 0.74 TWh, down 14.1% compared to June. Imports via the Kipoi gate were zero, as has been the case since January 2024.
First seven months of the year
In the first seven months of 2026, total net gas imports used for domestic consumption amounted to 40 TWh, down 2.6% compared to the same period in 2025.
LNG imports via the Agia Triada and Amfitriti terminals led the way with cumulative imports of 24.9 TWh and a 62.3% share of the total, reaching a historic high for this period (+35.2% compared to the first seven months of 2025).
This was followed by gas imports via Sidirokastro, which totaled 10.4 TWh (25.9% of the total), down 36.9% compared to 2025. Gas imports via the Nea Mesimvria gate totaled 5.92 TWh (14.8% of the total), down 7% compared to the same period in 2025 and the lowest level in three years.
Greece’s dependence on Russian gas
Greece has eliminated imports of Russian LNG since November 2024, thus already aligning itself with the EU’s subsequent decision to ban imports of Russian gas from January 1st, 2027. However, as for Russian pipeline gas, imports continue in quantities that vary significantly from month to month. A portion is used for domestic consumption, while the majority is supplied to neighboring countries, as exports through the Sidirokastro gate have remained at high levels since the beginning of the year.
More specifically, for the first seven months of 2026, total imports via Sidirokastro were 18.8 TWh. However, exports via Sidirokastro totaled 8.4 TWh, or 44.8% of imports. Thus, net imports via Sidirokastro totaled 10.4 TWh, the lowest level in the past three years for this period of the year.
Comparison between EU-27 Member States
First half of the year
According to the latest available Eurostat data for the EU-27 Member States[1], Greece ranked 6th in terms of the change in gas consumption between 2026 and 2025 for the first half of the year (January–June). More specifically, Greece reduced its gas consumption by 0.9% and was among the 7 Member States that reduced their gas usage, showing an improvement compared to the EU-27 average, which stood at +1.12%.
Among the remaining member states, the leaders for this period were Finland (-18%) and France (-8%), while Latvia (+28.2%) and Estonia (+23.9%) ranked among the worst performers.
