In August, the highest Russian gas imports of 2026 via Sidirokastro (2.62 TWh) were recorded, while LNG imports via Amfitriti doubled (1.13 TWh). Domestic consumption remained flat at July’s levels (5.6 TWh). In the first 8 months, gas consumption by the grids sector reached a record high (9.3 TWh), gas use in electricity was the 2nd highest on record (31.6 TWh), while industry was limited to 4.7 TWh (-3.4% compared to 2025). LNG ranked 1st in imports for the first 8 months (27.9 TWh), reaching a historic high for this period of the year. Exports for the first 8 months (11.9 TWh) reached a 3-year high, with 80.5% exported via Sidirokastro.
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 (August 2026). It also uses the latest monthly data published by Eurostat on imports of liquefied natural gas (LNG) imported from Russia (June 2026).
Consumption
August
In August 2026, domestic gas consumption was 5.6 TWh, remaining close to July’s levels. However, compared to August of last year, it increased by 4.9%.
The power generation sector, at 4.66 TWh, recorded the second-highest monthly consumption of the year and accounted for 83.1% of the total. This represented a 2.4% increase from July and an 8.9% increase from August 2025.
Next was the distribution networks sector with 553 GWh (9.9% of the total), though this represented the lowest consumption for both 2026 and the past twelve months. However, compared to August last year—when the lowest consumption of 2025 was recorded—consumption in the distribution networks increased by 11.7%. Compared to July, it decreased by 18.2%.
Industry ranked last in gas consumption with 392 GWh (7% of the total), representing a 2.4% increase compared to July. Compared to last August, however, gas consumption in industry fell significantly by 31.4%.
First eight months of the year
Cumulatively, over the first eight months of the year, total domestic gas consumption was 45.6 TWh, down 1.6% compared to 2025.
The power generation sector led in consumption with 31.6 TWh, marking the second-highest gas consumption for this period of the year, just 3.3% behind the 2025 record (32.7 TWh).
Next were the distribution networks, with 9.3 TWh, setting a consumption record for the first eight months and exceeding the 2022 high by 1.7%. The largest increases in volume were recorded n Athens, Thessaloniki, and Oinofyta. Compared to the same period last year, gas consumption in networks increased by 5.7%.
Industry ranked last, with 4.7 TWh for the first eight months of the year, down 3.4% compared to the same period in 2025.
As for the breakdown of domestic consumption across the three sectors, electricity generation accounted for 69.4%, distribution networks for 20.4%, and industry for 10.2%.
Exports
Total gas exports in August 2026 amounted to 1.7 TWh, up 14.9% from July and the third-highest figure of the year after March and February. Exports via Sidirokastro accounted for the lion’s share at 1.1 TWh, representing a slight increase of 3.7% compared to the previous month. Next was the Komotini-IGB gate, with exports reaching 0.29 TWh (+63.2%), followed by the Nea Mesimvria gate with exports of 0.27 TWh (+32%).
Cumulatively, over the first eight months of the year, gas exports reached 11.9 TWh, a three-year high. The majority of exports (80.5%) passed through Sidirokastro, totaling 9.54 TWh, followed by the Komotini-IGB gate with exports totaling 1.49 TWh, and finally the Nea Mesimvria gate with 0.82 TWh.
Imports
August
Total net imports into the National Transmission System—which covered domestic demand exclusively—amounted to 5.9 TWh in August, just 1.9% higher than July’s net imports.
LNG ranked first for August, despite a decrease in imports via Agia Triada, which was offset by an increase in imports via Amfitriti. More specifically, LNG imports via Agia Triada (Revythousa FSRU) totaled 1.87 TWh, down 18.2% compared to July, while imports via Amfitriti (Alexandroupolis FSRU) more than doubled, reaching 1.13 TWh.
In second place after LNG was the Sidirokastro gate (which is the main entry point for Russian gas), with net imports of 2.62 TWh, up 16.5% compared to the previous month.
In last place were imports through the Nea Mesimvria gate (through which Azerbaijani gas is imported via the TAP pipeline) at 0.31 TWh, down 57.7% compared to July. Imports via the Kipoi gate were zero, as has been the case since January 2024.
First eight months of the year
In the first eight months of 2026, total net gas imports used for domestic consumption amounted to 45.6 TWh, down 1.7% compared to the same period in 2025.
LNG imports via the Agia Triada and Amfitriti terminals ranked first for the eight-month period at 27.9 TWh, setting a record for this time of year. Compared to the same period in 2025, LNG imports increased by 31.8%.
Next were gas imports via Sidirokastro, which totaled 13 TWh for the eight-month period, down 28.2% and at a three-year low. Finally, gas imports via Nea Mesimvria totaled 6.2 TWh, down 14.7% and also at a three-year low.
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 eight months of 2026, total imports via Sidirokastro were 22.5 TWh. However, exports via Sidirokastro totaled 9.5 TWh, or 42.4% of imports. Thus, net imports via Sidirokastro totaled 13 TWh, the lowest level in the past three years for this period of the year.
