Azerbaijan and Bulgaria agreed to supply 1 billion m3 of gas per year through the Greece-Bulgaria Interconnector beginning in 2021.
However, because the IGB is still under construction, Azerbaijani gas is delivered to Bulgaria via the Kulata-Sidirokastro interconnection point.
Currently, the country receives only one-third of this volume.
The IGB Project (Gas Interconnector Greece-Bulgaria) is being carried out by the joint venture company ICGB AD, which was established in Bulgaria in 2011 and is owned by Bulgarian Energy Holding EAD and IGI Poseidon.
The IGB gas pipeline will connect to the Greek national gas transmission system in Komotini and the Bulgarian national gas transmission system in Stara Zagora.
The pipeline's planned length is 182 km, with a capacity of up to 3 billion m3 per year in the direction from Greece to Bulgaria.
The pipeline is designed to increase its capacity up to 5 bcm/y depending on market interest and the capacities of neighboring gas transmission systems.
The IGB project is critical in terms of increasing supply security and diversifying gas supplies for Bulgaria and the SEE region.
