Two LNG systems under development in Croatia and Greece are linked to the same regional trading objective: supporting non-Russian gas flexibility into Southeast and Central Europe. Croatia’s Krk LNG terminal is oriented toward Hungary, Slovenia, and Bosnia and Herzegovina. Greece’s Revythousa and Alexandroupolis terminals are positioned to supply Bulgaria, Serbia, North Macedonia, Albania, Romania, and potentially Hungary via the Vertical Corridor. The competition is increasingly affecting regional price formation and flow dynamics.
Krk capacity expansion and pipeline links
Croatia has increased its physical LNG capacity at Krk from around 2.9 bcm/year to 6.1 bcm/year. Pipeline upgrades associated with the terminal are designed to lift export capability toward Hungary to approximately 3.5 bcm/year. The same upgrade work targets exports toward Slovenia at around 1.5 bcm/year. In markets that are relatively small and structurally import-dependent, these incremental volumes can influence regional hub spreads and seasonal pricing behavior.
Revythousa and Alexandroupolis within south–north corridors
Greece’s LNG buildout is tied to a broader south–north flow strategy supported by long-term US LNG agreements. The expanded Atlantic SEE LNG Trade–Venture Global framework provides contracted supply visibility from around 2030 onward. AKTOR’s engagement with ALBGAZ extends corridor logic further into Albania, reinforcing Greece’s role as a regional distribution node. This positioning goes beyond an entry-point function for the Greek system.
Cargo routing economics and delivered pricing variables
For traders and buyers, route efficiency is a central comparison between the two gateway options. Cargoes routed through Krk may be more economical into Hungary and Slovenia because of shorter transmission paths and established infrastructure links. Cargoes entering via Alexandroupolis or Revythousa may be more competitive into Bulgaria and Serbia, as well as southern Balkan markets. Final pricing depends on shipping costs, regasification fees, transmission tariffs, interconnector availability, balancing charges, and perceived political and contractual reliability.
Regional trading impact across multiple supply sources
The dual-gateway setup is described as broadly positive for buyers because it reduces dependence on a single supply route and increases negotiating leverage across the region. At the same time, it adds operational complexity for traders managing cargo optimization across competing options. Traders must evaluate Greek and Croatian LNG alongside Romanian offshore potential, Azerbaijani pipeline flows, and Hungarian hub pricing signals within a more fragmented SEE gas matrix. The competitive outcome is therefore tied to which corridor can deliver higher degrees of flexibility, optionality, and tradable flow management.
LNG infrastructure serves as a starting point for access to cargoes that can be integrated into regional trading positions rather than treated only as physical import capacity.
