The 182km pipeline will provide a link between the national natural gas systems of Bulgaria and Greece with a capacity of 4.3 billion cubic metres per year. The project crosses the border at Komotini.
The project is being developed by ICGB, a joint venture of Bulgarian state-owned energy holding company BEH (50%) stake, Greek state energy firm DEPA (25%) and Italy’s Edison (25%). DEPA and Edison themselves are acting through a joint venture called IGI Poseidon.
The pipeline is being constructed in order to reduce Bulgaria's reliance on Russian gas.
The European Commission has designated the pipeline a Project of Common Interest (PCI)
The European Economic Recovery Plan (EERP) is providing €45 million in financing to support the project.
