Domestic gas consumption in July 2025 reached a quarterly high due to an increase in electricity (+19.4%) and networks (+4%). Gas demand in the first seven months hit a historic high of 41 TWh, with power generation accounting for 69.4%. Imports of Russian gas rose compared to the previous month, despite the EU’s plan to phase out Russian fossil fuels. In the seven-month period, LNG was the leading source of imports with 18.4 TWh, followed by Russian gas via Sidirokastro with 16.6 TWh.
Consumption
July
According to the latest available data from DESFA, total domestic gas consumption in July was 6.38 TWh, up 15.5% compared to June and the highest of the last three months. Τhe power sector recorded the largest change, with an increase of 19.35% (+838 GWh) compared to June, reaching 5.17 TWh. Demand in distribution networks reached 615.7 GWh, up by 3.9% (+22.8 GWh), while industrial demand fell by -1.03% (-6.2 GWh) to 599.6 GWh.
Compared to July 2024, total domestic gas consumption increased by 2.3% (+0.14 TWh). The increase was driven by higher demand in networks (12.89%, +70 GWh) and higher demand in electricity (1.5%, +76 GWh). In contrast, gas use in industry decreased by 0.54% (-3 GWh) compared to July 2024.
First seven months of the year
Cumulatively, in the first seven months of 2025, total domestic gas consumption reached 40.98 TWh, up 10.7% (+3.95 TWh), compared to the same period of 2024 – the highest level on record.[1]
The power generation sector recorded a 14.7% increase (+3.64 TWh), reaching 28.42 TWh and marking at least a decade-high in gas consumption for the seven-month period. Similarly, gas demand in networks rose by 18.3% (+1.28 TWh) compared to the previous year, totaling 8.31 TWh for the first seven months.
In contrast, industrial gas consumption reached 4.25 TWh, down by 18.6% (-0.97 TWh) compared to the first half of 2024.
Regarding the breakdown of consumption by use, electricity took a larger share compared to the first half, accounting for 69.4% of seven-month demand. Networks followed with 20.3% of demand, and industry ranked last with 10.4%.
Imports
July
Total imports in July 2025 were 6.4 TWh, an increase of 11.9% (+0.68 TWh) compared to Juny. Exports from 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 entry point were in first place with 2.74 TWh, closely followed by Russian gas imports via pipeline from the Sidirokastro entry point with 2.73 TWh. In third place was the Nea Mesimvria entry point with gas imports of 0.92 TWh.
Imports from the Agia Triada entry point remained at similar levels to those in June (2.75 TWh), while imports from the Sidirokastro entry point increased by 33% (+0.68 TWh). Imports from the Nea Mesimvria entry point recorded a slight increase of 1.4% (+0.01 TWh) compared to June.
LNG imports from the Amfitriti[2] entry point were zero due to a technical issue since late January[3]. Imports from the fifth entry point at Kipoi were also zero, as has been the case since January 2024.
First seven months of the year
Total fossil gas imports in the first seven months of 2025 amounted to 41.39 TWh, the highest on record for this period1. Compared to the first seven months of 2024, they increased by 5.97% (+2.33 TWh).
Leading import flows were LNG from the entry points of Agia Triada and Amfitriti, with a share of 44.5% (18.41 TWh), followed by the Sidirokastro entry point with 40.1% (16.6 TWh), and lastly the Nea Mesimvria entry point with 15.4% of imports for the first seven months (6.38 TWh).
LNG imports in the first seven months of 2025 rose by 70.3% (+7.6 TWh) compared to the same period in 2024. In contrast, Russian gas imports via the Turkstream pipeline decreased by 21.2% (-4.5 TWh), and Azeri gas imports via the TAP pipeline fell by 11.2% (-0.8 TWh).
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). For the first time, imports of Russian LNG were recorded in October 2022.
By mid-2023, Russian-sourced gas (both pipeline and LNG) had reclaimed its position as the first source of imports, reversing the post‑2022 trend that had seen non‑Russian LNG lead. This trend persisted for all the following months, until October 2024. However, in November, Russian gas fell to second place – a position it maintained for six months until March 2025.
In April 2025, Russian pipeline gas returned to the top import position, surpassing LNG (excluding Russian gas), and maintained this position through May 2025.
In early May 2025, the European Commission announced the RePowerEU plan to fully phase out imports of Russian fossil fuels. The plan aims to ban gas imports through new contracts and existing spot contracts by the end of 2025, as well as a complete ban on gas imports through long-term contracts by the end of 2027.
In July 2025, Russian gas imports to Greece via pipeline (through the Sidirokastro entry point) reached 2.73 TWh, marking an increase of 33% compared to June and hitting a six-month high. Additionally, they accounted for 43% of total imports and were at levels similar to LNG imports from the Agia Triada and Amphitritis terminals (2.74 TWh).
It is worth noting that since October 2024, Russian gas has been entering only via pipeline, while imports in the form of LNG are zero[4].
