November 2025 saw the highest exports in the last two years (1.34 TWh), with over 90% exported through Sidirokastro. LNG ranked first in imports for November with 3.26 TWh (78% from Agia Triada). It also ranked first for the 11-month period with 28.4 TWh. Domestic gas consumption was 5.5 TWh for November and 62.5 TWh for the first 11 months of 2025, the second highest domestic gas consumption on record after that of 2021 for the same period.
This analysis concerns domestic consumption, imports, and exports of fossil gas. It is based on the latest available data from DESFA on Validated Daily Natural Gas Deliveries / Off-takes (November 2025), as well as Data of N.G. Nominations / Allocations from DESFA’s New Commercial Information System (Νovember 2025). It also uses the latest monthly data published by Eurostat on imports of liquefied natural gas (LNG) imported from Russia (October 2025), and on gas consumption for comparison between the EU-27 Member States (October 2025).
Consumption
November
According to the latest available data from DESFA, total domestic gas consumption in November 2025 fell to 5.5 TWh, down 2.8% compared to October.
Gas use in the power and industrial sectors decreased by 6.9% and 10.4% respectively compared to October, resulting in consumption of 3.7 TWh and 754 GWh respectively. The networks sector was the only one to show an increase of 25.5% compared to the previous month, resulting in consumption of 1 TWh.
The power sector ranked first in gas consumption, but for the first time in the last seven months its share fell below 70% to 67.8%. Networks came in second place with a share of 18.4%, while industry ranked last with a share of 13.7%.
Compared to November 2024, total domestic gas consumption decreased by 17.9% (-1.2 TWh), with the largest percentage decrease in the networks sector (-21.9% or -284 GWh). Demand in power generation and in industry fell by 17.7% (-803 GWh) and -12.8% (-111 GWh) respectively.
First eleven months of the year
Cumulatively, in the first eleven months of 2025, total domestic gas consumption reached 62.5 TWh, an increase of 5.7% compared to the same period in 2024 and the second highest on record[1] since 2021.
The power generation ranked first in consumption with 44.2 TWh, a historic high, while compared to the same period in 2024, gas demand for electricity generation increased by 8.2% (+3.4 TWh).
In second place came the networks sector with 11.2 TWh and an increase of 13.6% (+1.34 TWh) compared to last year, which corresponds to a historic high for the eleven-month period. In last place was the industrial sector with 7.03 TWh, down 15.8% (-1.3 TWh) compared to the same period in 2024.
Regarding the breakdown of consumption by use, electricity retains the largest share of 70.8% of total consumption for the first ten months of 2025. This is followed by networks with a share of 18%, and finally, industry with 11.3% of consumption.
Exports
Total exports in November 2025 were 1.34 TWh, the highest of the year. The largest share of exports were from Sidirokastro gate – where Russian gas is imported – with 1.06 TWh, while exports from the IGB (Interconnector Greece Bulgaria) exiting at Komotini were 0.28 TWh. Exports from the Nea Mesimvria gate were zero.
Cumulatively in the first eleven months of 2025, fossil gas exports reached 7.09 TWh. The overwhelming majority of exports (93.6% or 6.63 TWh) were made from the Sidirokastro gate, while smaller quantities were exported from the gate at Komotini (0.44 TWh), and minimal quantities were exported from the gate at Nea Mesimvria (0.02 TWh).
Imports
November
Total imports into the National Transmission System, covering just domestic needs, reached 5.8 TWh in November 2025, a four-month high and up 2.1% compared to October.
LNG imports via the Agia Triada[2] gate rose to first place with 2.55 TWh and an increase of 10.4% compared to the previous month. Russian gas via pipeline from the Sidirokastro gate fell to second place with 1.63 TWh, down 33% compared to October.
Azeri gas from TAP imported via the Nea Mesimvria entry point remains in third place with 0.91 TWh, showing a slight increase of 3.4% compared to October.
In last place with0 0.71 TWh were LNG imports from the Amfitriti[3] entry point, which was reactivated and operating at maximum gasification capacity since the end of October. Imports from the fifth entry point at Kipoi also remained zero, as has been the case since January 2024.
First eleven months of the year
Total fossil gas imports in the first eleven months of 2025 amounted to 63.2 TWh, the second highest on record for this period after 2021. Compared to the first eleven months of 2024, total imports increased by 1.1% (+0.71 TWh), mainly due to increased LNG imports from Agia Triada, which more than offset the decline in Russian pipeline gas imports via Sidirokastro and Russian LNG.
In this period, Russian gas imports and LNG imports were very close in terms of volume. However, LNG from the entry points of Agia Triada and Amfitriti ranked first with a share of 44.9% (28.36 TWh), an increase of 63.8% (+11.05 TWh) compared to the first eleven months of 2024.
Imports of Russian gas from the Sidirokastro gate came second, with a 39.3% share and total imports of 24.81 TWh over eleven months, down 26.9% (-9.15 TWh) compared to the same period in 2024.
In last place was the Nea Mesimvria gate with a 15.9% share (10.03 TWh). Azeri gas imports via the TAP pipeline and the Nea Mesimvria gate have decreased by 10.6% (-1.2 TWh) compared to the same period in 2024.
Greece’s dependence on Russian gas
On December 3rd 2025, the European Commission agreed to completely ban imports of Russian natural gas in the form of LNG from 1st of January 2027 and via pipeline from 1st of October 2027.
In November 2025, Russian gas imports to Greece via pipeline amounted to 1.63 TWh, falling to second place after LNG, after two months in the first place. From November 2024 to now, LNG has been the leading source of imports, with the exception of the two two-month periods of April-May and September-October 2025.
It should also be noted that Russian gas (pipeline and LNG) was the primary source of gas imports for the entire period from June 2023 until October 2024, while since November 2024, Russian LNG imports to Greece have been zero.
Comparison between EU-27 Member States
According to the latest available Eurostat data for the EU-27 Member States[4], Greece ranked 6th worst, as it increased gas consumption between 2024 and 2025 for the ten-month period from January to October by 8.1%, double the EU-27 average (4%). However, this is a relative improvement, as it fell one place compared to the corresponding comparison for the nine-month period of 2025.
Of the remaining Member States, nine reduced their consumption, led by Finland, Sweden and Estonia (-19.8%, -14% and -11.6% respectively), while 16 countries increased their consumption, with Austria, Poland and Slovenia in the worst positions (+14.9%, +13.3% and+10.6% respectively).
