Balkan Stream is a pipeline which transports Russian natural gas from Turkey to Bulgaria, Serbia[1] and Hungary.
[2][3] It is an extension of Turk Stream.
[4][5] Annual capacity is almost 16 bcm from Turkey[6] and 1.8 bcm onwards to Serbia.
[7] The Serbian chunk of the project, purportedly named "Serbian stream", is headed by Srbijagas (or "South Stream Serbia AG"), the state-owned natural gas provider of Serbia and financed by Gazprom[8][need quotation to verify].
Bulgarian and Hungarian parts of Balkan Stream, however, are owned by local gas operators.
