The Balkan Stream project is sometimes referred to as the "Expansion of Bulgartransgaz EAD gas transmission infrastructure in the section from BG-TR to BG-RS"[1] and "Balkan Gas Hub-Necessary expansion of the Bulgarian gas transmission system." It is an extension to the TurkStream Gas Pipeline, from Russia to Turkey.[3] As part of the Balkan Gas Hub, a European 'Project of Common Interest', Bulgartransgaz was awarded a €630,467 public money grant for a feasibility study from the Connecting Europe Facility.[6]

In September 2019, Global Business Club reported that construction had begun and 90% of pipes for the Balkan Stream have already been delivered to Bulgaria from Russia.[9]

In December 2020 the pipeline was put into operation.[7]

The European Network of Transmission System Operators for Gas (ENTSOG) refers to the project as "TRA-F-592". [1]
