The IGB (Greece-Bulgaria Gas Interconnector) project is being implemented by the joint venture company ICGB AD, registered in Bulgaria in 2011 with shareholders BEH EAD (50%) and IGI Poseidon (50%). The co-shareholder IGI Poseidon is a company registered in Greece, with shareholders the Greek company DEPA International Projects S.A. (50%) and the Italian energy group Edison S.p.A (50%).
The company ICGB AD is the owner of the IGB gas pipeline, financing its implementation, distributing its transmission capacity and receiving revenues from the transmission of natural gas.
The IGB gas pipeline connects with the Greek national gas transmission system (DESFA S.A.) and the Trans-Adriatic gas pipeline (TAP AG) in Komotini (Greece), and with the Bulgarian gas transmission system (Bulgartransgaz EAD) in Stara Zagora. The total length of the gas pipeline is 182 km, the diameter of the pipe - 32'' - and the design capacity of up to 3 billion m3/year in the direction Greece - Bulgaria. Depending on the market interest for larger capacity and the possibilities of the neighboring gas transmission systems, the capacity of IGB is designed with the option for increase up to 5 billion m3/year with additional construction of a compressor station.
The interconnector represents an energy project of utmost importance for Greece, Bulgaria and the wider region of Southeastern Europe, leading to stronger energy connectivity and enhanced security of the natural gas sources.
The IGB pipeline holds strategic importance for both Greece and Bulgaria. The interconnector will provide direct access for Bulgaria to the Southern Gas Corridor and has great synergy with other major energy projects like TAP, TANAP and the LNG terminal near Alexandroupolis.
