Greece’s TSO, DESFA, has published its gas data for 2025. Domestic consumption increased by 6 per cent compared to 2024, reaching 70.16 terawatt-hours (TWh) from 66.20 TWh. This confirms that the Greek market continued its upward trend and that natural gas remains a key pillar of the country’s energy system. Total demand, including exports, stood at 78.75 TWh, up from 69.10 TWh the previous year, a 14 per cent year on year increase.
Exports almost tripled, rising by 196.21 per cent to 8.59 TWh from 2.90 TWh in 2024, strengthening Greece’s transit role in the wider region.
Imports reached 78.88 TWh in 2025, up 13.71 per cent from 69.37 TWh in 2024. The largest volumes entered via the Sidirokastro entry point, from Bulgaria, accounting for 44.6 per cent of total imports, or 35.16 TWh. This was followed by the Revithoussa LNG terminal, through which 29.95 TWh were imported, corresponding to 38.0 per cent of total imports and an increase of 63.3 per cent year on year, despite the terminal being out of operation for scheduled maintenance between 22 May and 11 June 2025. Imports via the Nea Mesimvria entry point, connected to the TAP pipeline, amounted to 11.08 TWh, or 14.1 per cent of the total, while 2.69 TWh, or 3.4 per cent, entered through the Amphitrite entry point at the Alexandroupolis FSRU.
LNG unloadings at the Revithoussa terminal totalled 30.84 TWh in 2025, delivered by 49 tankers, compared with 27 in 2024. The United States remained the largest LNG supplier, with 26.56 TWh, up 98.36 per cent year on year and representing 86.12 per cent of total LNG volumes. This was followed by Nigeria with 1.37 TWh, Egypt with 1.00 TWh, Algeria with 0.98 TWh and Norway with 0.93 TWh.
The LNG truck loading service also expanded strongly. A total of 707 LNG trucks were loaded in 2025, up 171 per cent from 261 in 2024. The volume handled reached 31,867 cubic metres of LNG, or 212,227 MWh in energy terms, an increase of more than 174 per cent year on year. This reflects growing demand for flexible small-scale LNG supply for industrial consumers, off-grid areas and regional markets.
By consumer category, electricity generation accounted for the largest share of domestic gas use in 2025, with 70.28 per cent of total consumption, up 8.49 per cent compared with 2024. Consumption via distribution networks reached 13.05 TWh, an increase of 11.25 per cent, while consumption by industry and CNG stations fell by 13.53 per cent.
Overall, 2025 was a year of strong growth, marked by a sharp rise in exports and a further strengthening of Greece’s role as a regional transit and energy hub. Increased utilisation of the Revithoussa terminal and the rapid expansion of LNG truck loading underlined the importance of DESFA’s infrastructure in enhancing system flexibility, supporting supply diversification and meeting growing demand both within Greece and in neighbouring markets.
