The first batch of Azerbaijani natural gas arrived in Bulgaria via the Gas Interconnector Greece-Bulgaria (IGB) natural gas pipeline project. This was reported by the Bulgarian radio station BNR, which added that the pilot amount of raw materials is expected to be imported by the end of June.

The IGB pipeline will join the Trans Adriatic Pipeline as well as the Greek Natural Gas Transmission Network and, in the future, the Alexandroupolis FSRU Terminal—the proposed floating storage and regasification unit (FSRU) import terminal at the Greek port city of Alexandroupolis.

The initial capacity of this natural gas pipeline is 3 billion cubic meters per year, with the possibility of reaching to 5 billion.

The IGB pipeline is on the European Commission's list of projects of common interest and has received €84 million in EU co-funding.
