Results from European annual gas transmission capacity auctions indicate market interest in using the Alexandroupolis LNG terminal and the Trans-Adriatic Pipeline as long-term routes for transporting gas.
Companies have booked all the capacity offered at the Amfitriti interconnection point — where sendout from the 4.3mn t/yr Alexandroupolis LNG terminal enters the Greek grid — for 2026-34. During the annual capacity allocation process, shippers reserved the full 4 GWh/d on offer for the 2026–27 gas year and the 29 GWh/d available for 2030–35. For the 2035–41 period, companies booked 23 GWh/d of the 29 GWh/d offered (see table).
The Alexandroupolis LNG terminal is part of the vertical gas corridor project, which aims to strengthen south-to-north gas flows across southeastern and central Europe and help replace Russian supplies from October 2027.
Firms also showed high interest in the Amfitriti Route 2 product, which enables the transfer of gas from the Greek grid to Ukraine, booking the full 7 GWh/d for 2026-27, and all available capacity for the subsequent periods, booking 2 GWh/d for 2027–29, 2.5 GWh/d for 2029–30, and 5 GWh/d for 2030–31. This is ahead of the planned introduction of long-term capacity, which was announced earlier this year.
Capacity was also booked at interconnection points further along the transportation route.
Long-term capacity bookings were secured at the Greek Nea Mesimvria interconnection point, which is used to transport Azeri gas through the 10bn m³/yr Trans-Adriatic Pipeline. Capacity reservations were 1 GWh/d for 2026–27, rising to 6 GWh/d for 2027–29 and peaking at 35.3 GWh/d for 2029–34, before declining to 5 GWh/d for 2034–41.
The Nea Mesimvria bookings may reflect expectations of higher Azeri exports to Europe. Azerbaijan committed in 2022 to increase its deliveries to the EU to 16bn–20bn m³/yr by 2027 under an agreement with the European Commission. Additional capacity could also become available after the June start-up of BP's Azeri Central East platform at the offshore Azeri–Chirag–Guneshli field.
Bookings were also made at the Oberkappel and Uberackern interconnection points on the German-Austrian border of 504 MWh/d and 4.4 GWh/d, respectively, for 2026-27, and 38.7 GWh/d and 51.6 GWh/d for 2027-28. Flows at these points were near technical capacity for most of the second quarter.
