The Greek natural gas transmission system operator DESFA reported that total natural gas demand, including exports, reached 56.36 TWh in the first nine months of 2025, up 16.7% from 48.31 TWh in the same period in 2024.
The main driver of growth was the export market. Gas exports surged to 5.06 TWh, a substantial increase from just 0.66 TWh last year, representing a rise of over 660%. Domestic demand also increased, climbing 7.7% to 51.30 TWh, compared with 47.65 TWh in 2024.
Electricity generation remained the largest consumer of domestic gas, accounting for 71% of usage with 36.45 TWh. Gas distributed through networks rose by 18.1% to 9.42 TWh, making up 18% of total demand. Industrial users and CNG stations consumed 5.43 TWh, a decline of 17%, representing 11% of domestic consumption.
On the supply side, LNG became a dominant source, covering over 40% of Greece’s total gas imports, compared with around 26% a year earlier. The Revythoussa terminal served as the primary entry point despite being offline for maintenance from 22 May to 11 June. It handled 36 LNG carriers carrying 22.41 TWh, up 81.6% from 12.34 TWh in 2024, compared with only 17 carriers in the same period last year. The Alexandroupoli terminal contributed 1.03 TWh before temporarily suspending regasification services on 22 January.
The United States remained the largest LNG supplier, delivering 19.62 TWh or 88% of total volumes, more than doubling its supply from 8.02 TWh in 2024. Nigeria supplied 1.37 TWh, followed by Norway with 0.93 TWh and Algeria with 0.49 TWh. Pipeline gas imports declined. Sidirokastro delivered 25.46 TWh, covering 45% of total imports, down 3.3% from 26.32 TWh in 2024. Imports via the TAP interconnection through Nea Mesimvria fell 14.7% to 8.20 TWh, compared with 9.61 TWh last year.
DESFA also reported strong growth in LNG truck loading services at Revythoussa. In the first nine months of 2025, 494 trucks were loaded with 148.05 GWh of LNG, nearly three times the 51.28 GWh handled by 174 trucks in the same period in 2024. This sharp increase highlights the growing role of truck-loaded LNG as a flexible solution to meet the energy needs of remote networks and industrial consumers in Greece and neighboring regions.
