Balkan Stream

Balkan Stream is a pipeline which transports Russian [natural gas] from Oil and [gas in Turkey|Turkey] to Bulgaria, Serbia and Hungary. It is an extension of Turk Stream. Annual capacity is almost 16 bcm from Turkey and 1.8 bcm onwards to Serbia.
The Serbian chunk of the project, purportedly named "Serbian stream", is headed by Srbijagas, the state-owned natural gas provider of Serbia and financed by Gazprom. Bulgarian and Hungarian parts of Balkan Stream, however, are owned by local gas operators.
