Greece’s natural gas market strengthened in the first half of 2026, with cross-border flows identified by DESFA as the main driver of overall demand growth. The transmission system operator said the latest figures point to an expanding role for Greece as a regional transit hub, supported by higher exports and stronger LNG activity.
Demand and trade dynamics in the first half of 2026
Between January and June 2026, total natural gas demand reached 43.09 TWh, up 15.06% year on year from 37.45 TWh in the same period of 2025. DESFA reported that external demand was the main contributor, with gas exports rising to 8.72 TWh from 2.86 TWh. The increase reflected growing importance in supplying neighbouring markets through regional interconnections.
Domestic consumption remained broadly stable over the period, with gas demand within Greece slipping by 0.64% to 34.37 TWh from 34.59 TWh. DESFA said lower consumption from electricity producers was largely offset by higher demand from industrial users, compressed natural gas (CNG) applications and distribution networks. Imports tracked the overall market expansion, increasing 14.76% year on year to 43.07 TWh.
LNG imports and entry points
The Revythoussa LNG terminal remained Greece’s leading import gateway, receiving 18.61 TWh, equivalent to about 43% of total imports. DESFA reported that LNG deliveries through Revythoussa rose by more than 25% versus the first half of 2025. The Sidirokastro entry point ranked second with 15.47 TWh, followed by Nea Mesimvria at 5.53 TWh.
LNG imports via the Alexandroupoli floating LNG terminal also increased, reaching 3.46 TWh. DESFA said this level was more than three times higher than in the previous year’s first half.
Gas use in power generation and other sectors
Electricity generation continued to be the largest source of domestic gas demand, despite a moderate decline compared with 2025. Gas-fired power producers consumed 22.41 TWh, down from 23.25 TWh, accounting for around 65% of total domestic gas consumption.
Distribution networks increased consumption to 8.08 TWh, up from 7.69 TWh. Industrial users and the CNG sector together raised demand to 3.88 TWh, compared with 3.65 TWh.
LNG supply sources and cargo volumes
The United States remained Greece’s largest LNG supplier during the first half of 2026, with US cargoes reaching 12.67 TWh. DESFA said this represented around 70% of LNG volumes delivered through Revythoussa.
Nigeria supplied 4.16 TWh, while additional volumes arrived from Egypt, Algeria and Mauritania. Overall, DESFA recorded 24 LNG shipments delivering 18.18 TWh, compared with 27 cargoes supplying 14.66 TWh in the same period of 2025.
LNG truck loading growth beyond terminals
Diversification of LNG activity extended beyond pipeline and terminal operations, according to DESFA reporting on truck-loading services. The number of supplied trucks increased to 537 during the six-month period, up from 273 a year earlier.
