Domestic gas consumption in April (4.4 TWh) hit a 7-month low due to declines in all three sectors. Cumulatively for the first four months of 2026, total consumption remained at the same level as in 2025 (24.8 TWh), while consumption in networks reached a 4-year high (6.7 TWh). The primary source of imports for the 4-month period was LNG via Revythousa (17 TWh), despite a decline in April and the shutdown for maintenance of the Alexandroupolis FSRU. Exports saw a sharp decline in April (0.6 TWh). Compared to the other EU-27 member states for the first quarter of 2026, Greece ranked 6th, reducing gas consumption by 2.2% compared to 2025.
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 (April 2026). It also uses the latest monthly data published by Eurostat on imports of liquefied natural gas (LNG) imported from Russia (March 2026).
Consumption
April
In April 2026, domestic gas consumption fell to 4.4 TWh, a 7-month low. Compared to March, it decreased by 33.8%; however, compared to April of last year, it increased by 11.2%.
The electricity sector fell to a 12-month low at 2.8 TWh (-31.6% compared to March), yet it still accounted for the largest share of consumption (64.2%). This was followed by networks with 986 GWh and the largest decrease compared to March (-43.1%). Last was the industrial sector with 577 GWh, which fell to an 11-month low. However, compared to April 2025, it increased by 19.7%.
First four months of the year
Cumulatively in the first four months of the year, total domestic gas consumption was 24.79 TWh, matching the consumption recorded in 2025 for the same period. Compared to the first four months of last year, gas consumption for electricity generation decreased, while consumption by networks and industry increased.
More specifically, the electricity sector remained the largest consumer at 15.3 TWh, though this represented a 2.95% decrease compared to 2025, which marked a historic high. Its share of total gas consumption fell from 63.5% in 2025 to 61.7%.
Networks were the second-largest consumer at 6.7 TWh (+3.5% compared to 2025), marking the highest gas consumption over the past four years for this period. The networks’ share reached 26.8%.
Industry came in last with 2.9 TWh, representing a 9.4% increase compared to the same period in 2025. Industry’s share for the four-month period was 11.5%.
Exports
Total gas exports in April 2026 amounted to 0.61 TWh, marking the lowest level for 2026 and to ¼ of the level recorded in March, when a 3-year record was reached. This is mainly due to the massive decline in exports via Sidirokastro (-42.8%) and via Nea Mesimvria (-44.4%), as well as zero exports via Komotini-IGB.
However, cumulatively over the first four months of the year, exports reached 6.6 TWh, marking a 340.7% increase compared to the same period in 2025. 80% of gas exports were via the gate of Sidirokastro, 15.5% via the gate at Komotini-IGB, and 4.5% via the Nea Mesimvria gate.
Imports
April
Total imports into the National Transmission System, covering domestic needs exclusively, amounted to 4.35 TWh, down 34.9% from March, mainly due to a decline in LNG imports.
Despite the decline, LNG imports remained in first place in April thanks to LNG imports via the Agia Triada gate (Revythousa FSRU), which reached 2.1 TWh (-42.8% compared to March). Imports via the Amfitriti gate (Alexandroupolis FSRU) were zero, as the terminal is currently undergoing a 3-month maintenance period.
The Sidirokastro gate (which is the main entry point for Russian gas) ranked second in imports with net imports of 1.3 TWh, down 11.5% compared to March.
In third place was the Nea Mesimvria gate (through which Azerbaijani gas is imported via the TAP pipeline) with 0.93 TWh, double the imports recorded in March. Imports from the Kipoi gate were zero, as has been the case since January 2024.
First four months of the year
In the first four months of 2026, total net gas imports used for domestic consumption amounted to 24.8 TWh, down 0.9% compared to the same period in 2025.
Total LNG imports (Agia Triada gate + Amfitriti gate) reached 17.04 TWh, a record high for this period. In contrast, total imports via the Sidirokastro gate fell to 10.7 TWh, while total imports via the Nea Mesimvria gate were 3.7 TWh. As for exports, these amounted to 5.3 GWh via Sidirokastro, 1.02 via Komotini-IGB, and 0.3 via Nea Mesimvria.
As for the breakdown of net imports, LNG accounted for 68.7%, the highest share in the last three years for this period. The Sidirokastro gate accounted for 21.7%, while the Nea Mesimvria gate accounted for 13.7%.
Greece’s dependence on Russian gas
Greece has eliminated imports of Russian LNG since November 2024, thus already aligning itself with EU’s subsequent decision to ban imports of Russian gas from January 1st, 2027. However, as for Russian pipeline gas, imports continue. 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 four months of 2026, total imports via Sidirokastro were 10.7 TWh. However, exports via Sidirokastro amounted to half the volume of imports, resulting in net imports of 5.4 TWh, a 43% decrease compared to last year.
Comparison between EU-27 Member States
First quarter 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 quarter of the year (January–March). More specifically, Greece reduced its gas consumption by 2.2%, a figure nearly five times the EU-27 average (-0.45%) and was among the 9 Member States that showed an improvement.
Among the remaining member states, the leaders for this period were France with -10.6% and Finland with -10.1%. At the bottom of the list were Estonia with +39% and Latvia with +40%.
