Greece’s natural gas exports rose by almost 169% in the first nine months of 2026, reaching 13.60 TWh between January and September. Exports were up from 5.06 TWh in the corresponding period of 2025. Total demand, including exports, increased 12.72% to 63.53 TWh.
The higher export volumes coincided with lower domestic gas use. Domestic consumption fell 2.67% to 49.93 TWh. Power producers remained the largest domestic customers, accounting for approximately 70% of demand.
LNG deliveries support cross-border flows via key terminals
The export increase was supported by stronger activity at Revythoussa and Alexandroupoli, which together injected 30.10 TWh into the transmission network. Deliveries through Alexandroupoli’s Amfitriti connection rose to 5.82 TWh, from 1.03 TWh in the same period of 2025. Revythoussa supplied 24.28 TWh through Agia Triada, an increase of 11.58%.
Total Greek gas imports increased 12.61% to 63.57 TWh. The Sidirokastro connection with Bulgaria remained the largest entry point, handling 25.51 TWh, compared with 25.46 TWh a year earlier. Another 7.96 TWh entered through Nea Mesimvria from the Trans-Adriatic Pipeline.
LNG supply mix at Revythoussa and cargo volumes
LNG unloaded at Revythoussa totalled 32 cargoes, carrying 24.25 TWh. This compared with 36 cargoes delivering 22.41 TWh a year earlier, with higher unloaded volumes despite fewer arrivals indicating an increase in average cargo size . The United States supplied 17.88 TWh, accounting for approximately 74% of terminal cargo deliveries.
Nigeria followed with 4.16 TWh, or 17.2%. Other suppliers included Congo with 0.86 TWh, Egypt with 0.51 TWh, Algeria with 0.49 TWh, and Mauritania with 0.35 TWh. Nigeria’s share was part of a wider set of LNG origins feeding Revythoussa during the period.
