April recorded the lowest domestic consumption in the last 17 months. For the first time in 2025, monthly gas use in electricity fell compared to last year, while grids recorded a large increase (+58%). In April, Russian gas rebounded, as it surpassed LNG imports for the first time in the last six months. Greece remains in the worst position in the ranking among EU Member States, with the largest increase (+28.4%) in gas consumption in the first quarter of 2025 compared to 2024.
Consumption
April
According to the latest available data from DESFA, the total domestic consumption in April 2025 was 3.92 TWh, the lowest in 2025 but also in the last 17 months (since December 2023).
Compared to April last year, gas consumption decreased by 6.5% (-0.27 TWh). The largest decrease was recorded in industry, where demand fell by 41% (-0.33 TWh). Gas demand for electricity also fell by 11.5% (-0.31 TWh) compared to April 2024. In fact, this is the first time this has happened in 2025, after comparing monthly demand in the electricity sector between 2025 and 2024. In contrast, gas usage in grids increased strongly by 58% (+0.38 TWh).
First four months of the year
Cumulatively in the first four months of 2025, total gas consumption was 24.78 TWh and the highest compared to the same period of the previous 5 years, which is due to the very high consumption in January and February 2025.
Compared to the corresponding four months of 2024, demand recorded an increase of 21.5% (+4.38 TWh). Electricity and grids saw an increase (+4.02 TWh – 34% and +1.06 TWh – 19.8% respectively). In contrast, demand in industry fell by 21.1% (-0.7 TWh).
The breakdown of consumption by use remains the same, with electricity accounting for 63.5% (15.75 TWh) of total consumption for the first four months. This is followed by grids with 25.9% (6.43 TWh) and industry with 10.5% (2.6 TWh).
We note that compared to the same period in 2024, the share of electricity in total consumption has increased (from 57.5% to 63.5%), while the shares of grids and industry have decreased (for grids from 26.3% to 25.9% and for industry from 16.2% to 10.5%).
Imports
April
Total imports this month were 3.93 TWh, and the lowest since 2023 for the month of April. Exports from the IGB (Interconnector Greece-Bulgaria) exiting at Komotini and Sidirokastro were zero.
Regarding entry points, this month saw the reverse picture from that of March, with gas imports through pipelines being higher than liquefied natural gas (LNG) imports. Specifically in April, the Sidirokastro gate led in gas imports with 2.05 TWh, followed by the gate of Nea Mesimvria with 0.93 TWh. In third place was the Agia Triada gate with LNG imports of 0.94 TWh.
Imports from the Amfitriti gate were zero due to the technical problem that the plant has been experiencing since late January. Imports from the fifth entry gate at Kipoi were also zero (as they have been since January 2024).
First four months of the year
As for the first four months of 2025, total gas imports were 24.97 TWh, an increase of 3.3% compared to the same period in 2024. First in import flows was LNG from the Agia Triada and Amfitriti entry gates with a 47.7% share (11.9 TWh). The second source was Russian gas from the Sidirokastro gate with 37.8% (9.45 TWh), followed last by Azeri gas via the TAP pipeline from the gate of Nea Mesimvria with 14.4% (3.6 TWh).
For the first four months, Russian gas imports were at similar levels to those in 2024, however they have moved into second place, behind LNG imports especially from the Agia Triada gateway, which increased significantly leading to the top of the ranking.
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 the Sidirokastro gateway 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 gas in total (from pipeline and LNG) became the first source of imports, reversing the trend set after the invasion of Russia to Ukraine and up to that point, when LNG from other countries had been a leading source. This trend was maintained for all the following months, until October 2024. A month later, in November, Russian gas dropped to second place, which continued until March 2025.
In April 2025, after six months, Russian gas returns to the top position for imports, surpassing LNG by 1.1 TWh. It is worth noting that since November 2024, Russian gas has been entering only by pipeline, while imports in the form of LNG are zero[1].
Comparison between EU-27 Member States
According to the latest available Eurostat data[2] (March 2024), Greece recorded the highest percentage increase (+28.4%) in gas consumption between 2024 and 2025 for the first three months of the year in the EU-27. Only five Member States decreased their gas consumption with Sweden, Finland and Estonia recording a decrease of more than 20% (24.7%, 21.8% and 20.01% respectively). 19 Member States increased their gas consumption, with Austria and Croatia, like Greece, increasing by more than 20% (21.7% and 22.1% respectively). Due to this picture of the Member States, the EU-27 experienced an average increase of 7.68% in gas consumption between 2024 and 2025.
