In August 2025, domestic gas consumption reached 5.34 TWh, down 16.4% compared to July due to reduced usage in all three sectors. However, in the first 8 months of 2025, the power generation sector reached a decade high of 32.7 TWh, +11% compared to 2024. Gas demand in networks also increased (+18%), reaching 8.8 TWh. In the eight-month period, the first source of imports was LNG with 21.2 TWh. In second place is Russian gas via Sidirokastro with 18.2 TWh, despite the large decrease in August (-40%) compared to July.
Consumption
August
According to the latest data available from DESFA on validated Daily Gas Deliveries and Off-takes[1], total domestic gas consumption in August 2025 was 5.34 TWh, down 16.4% compared to July. Distribution networks had the highest percentage decrease compared to the previous month (-19.6%), reaching 495 GWh. After a quarter of steady growth (May-June-July), demand in the power sector fell to 4.27 TWh (-17.4% compared to July). Demand in industry continued the downward trend that had started the previous month, reaching 570 GWh (-4.7%).
Compared to August 2024, total domestic gas consumption fell by 7.2% (-414 GWh). The decrease was mainly due to lower gas use in electricity (-8.1%, -377 GWh). Demand in industry decreased year-on-year by 110 GWh (-16.2%), but this was offset by an increase in demand in networks of 73 GWh (+17.4%).
First eight months of the year
Cumulatively, in the first eight months of 2025, total domestic gas consumption was 46.32 TWh, up 8.3% (+3.54 TWh) compared to the same period in 2024 and the second highest level on record[2] since 2021.
The power generation sector with 32.7 TWh reached a decade high. Compared to the same period in 2024, demand increased by 11% (+3.26 TWh). Gas demand in networks reached 8.8 TWh, an increase of 18.2% (+1.36 TWh) from 2024. The industrial sector followed the opposite trend as it decreased by 18.3%, reaching 4.8 TWh.
Regarding the breakdown of consumption by use, electricity had the largest share, accounting for 70.6% of the eight-month demand. Networks followed with 19% of demand, and industry ranked last with 10.4%.
Imports
August
Total imports in August 2025 were 5.33 TWh, down 16.7% (-1.06 TWh) from July. Exports from the IGB (Interconnector Greece Bulgaria) exiting at Komotini and from Sidirokastro gate were zero.
Regarding the entry points, liquefied natural gas (LNG) imports from the Agia Triada[3] entry point was in first place with 2.75 TWh, remaining stable at this level since June 2025. Russian gas via pipeline from the Sidirokastro gate followed with 1.64 TWh, down 40% (-1.09 TWh) compared to July. The Nea Mesimvria entry point remained in third place with 0.94 TWh and stable import levels during the last six months (since March 2025).
LNG imports from the Amfitriti[4] entry point were zero due to a technical issue since late January[5]. Imports from the fifth entry point at Kipoi were also zero, as has been the case since January 2024.
First eight months of the year
Total fossil gas imports in the first eight months of 2025 amounted to 46.72 TWh and were the second highest on record for this period2 after 2021. Compared to the first eight months of 2024, total imports increased by 4.1% (+1.85 TWh), mainly due to a large increase in LNG imports, which more than covered the decrease in Russian gas imports via Sidirokastro.
Leading import flows were LNG from the entry points of Agia Triada and Amfitriti, with a share of 45.3% (21.16 TWh). Compared to the first eight months of 2024, LNG imports increased by 76.8% (+9.2 TWh).
Imports from the Sidirokastro gate came second, with a 39% share and total imports of 18.24 TWh over eight months. Compared to the same period in 2024, Russian gas imports via the Turkstream pipeline and the Sidirokastro gate decreased by 26.2% (-6.47 TWh).
In last place was the Nea Mesimvria gate with a 15.7% share (7.3 TWh). Azeri gas imports via the TAP pipeline and the Nea Mesimvria gate have decreased by 10.7% (-0.88 TWh) compared to the same period in 2024.
Greece’s dependence on Russian gas
Fossil gas from Russia is imported into Greece in two different forms, either as gas through the Turkstream pipeline from Sidirokastro gate or in the form of liquefied natural gas (LNG). In early May 2025, the European Commission announced a plan to completely ban imports of Russian fossil fuels. The plan aims to ban gas imports through new contracts and existing spot contracts[6] by the end of 2025, and a complete ban on gas imports through long-term contracts by the end of 2027.
Russian gas (pipeline and LNG) was the first source of gas imports to Greece from June 2023 until October 2024. As of November 2024, and according to the latest Eurostat data, Russian LNG imports to Greece were zero[7].
In August 2025, Russian gas imports to Greece via pipeline reached 1.64 TWh, a decrease of 40% compared to July and a five-month low. They accounted for 31% of total monthly imports, well below the share of LNG, which has held the lead since November 2024 apart from a two-month period during April-May 2025.
Comparison between EU-27 Member States
According to the latest available Eurostat data[8] (July 2024), Greece recorded a 9.8% increase in gas consumption between 2024 and 2025 for the period January – July, the 6th highest increase in the EU-27 and more than double the EU-27 average (+4.5%). In the same period, 10 Member States decreased their gas consumption, with Sweden and Estonia leading the way (-19.7% and -15.2% respectively). Of the remaining 16 Member States, Croatia and Austria saw the largest increases in gas consumption (+15.95% and +16.4% respectively).
