US liquefied natural gas (LNG) is increasingly approaching Russian pipeline gas volumes in Greece after a year-on-year rise of more than 70 percent. From January through early August 2025, a total of 19.3 TWh of LNG was delivered to the Revythoussa and Alexandroupoli terminals, with US shipments accounting for over 80 percent of that total. Pipeline gas, primarily Russian volumes entering at Sidirokastro on the Greek-Bulgarian border, reached 20.8 TWh during the same period.
The energy mix in Greece has shifted significantly over the past year. In mid-2024, LNG represented 30 percent of supply while Russian gas made up 50 percent. Today, LNG accounts for 41 percent and Russian gas 44 percent, with the remainder provided by Azerbaijani gas via the Trans Adriatic Pipeline (TAP). In July 2024, Russian gas covered 60 percent of demand, a share that has since declined.
Shipping activity reflects this trend. Six US LNG carriers arrived at Revythoussa in July, with seven scheduled for August and six for September, totaling 19 shipments across the three months. While the overall volumes remain moderate, they demonstrate steady growth driven by a 19.4 percent increase in domestic electricity demand in July and higher exports to southeastern Europe.
The restart of the Alexandroupoli floating storage and regasification unit (FSRU) after a seven-month outage is expected to boost LNG flows further. Until October, the facility will operate at 25 percent of its full capacity, equivalent to 45.4 GWh per day. This timing coincides with increased utilization of the Vertical Gas Corridor, enhancing Greece’s role as a transit hub for non-Russian gas supplies destined for Ukraine.
