It starts from Russkaya compressor station near Anapa in Russia's Krasnodar Region, crossing the Black Sea to the receiving terminal at Kıyıköy.

In 2009, Russia′s prime minister Vladimir Putin proposed the Blue Stream II line parallel to the original pipeline.

[2] The TurkStream (then named Turkish Stream) project was announced by Russia′s president Vladimir Putin on 1 December 2014 during his state visit to Turkey, when a memorandum of understanding was signed between Gazprom and BOTAŞ.

Also in July 2015, a memorandum of understanding between Greece and Russia was signed for the construction and operation of the TurkStream section in the Greek territory.

[5][6] On 10 October 2016, Russia and Turkey officially signed the intergovernmental agreement in Istanbul to execute the project.

[11] Gazprom began shipping gas via TurkStream, including to Bulgaria and North Macedonia, on 1 January 2020, replacing supplies via the Trans-Balkan pipeline through Ukraine and Romania.

On 13 January 2025, the Russian defence ministry reported a failed Ukrainian drone attack on a TurkStream compressor station in the Krasnodar region, which Russia called an "act of energy terrorism".

For Gazprom the preferable option is to export gas from the second line to Bulgaria, Serbia, Hungary, Slovakia, and Austria.

[24] The other planned follow-on projects included also the Tesla pipeline, to run from Greece to North Macedonia, Serbia and Hungary, ending at the Baumgarten gas hub in Austria.

[13] TurksStream changes the regional gas flows in South-East Europe by diverting the transit through Ukraine and the Trans Balkan Pipeline system.

According to Gokhan Yardim, former manager of the state-owned energy company GOTA, this will open up the possibility of a further 15 billion cubic meters of gas transit.

[29] In 2024, Solvakia entered into a pilot contract to buy natural gas from Azerbaijan to reduce the impact of the Ukrainian closure of the pipeline for Russian supplies in 2025.
