According to data from the European Network of Transmission System Operators for Gas (ENTSO-G), Russian gas exports to Europe via the TurkStream pipeline increased by 7.3 percent year-on-year in the first half of 2025, reaching a total of 8.3 billion cubic meters. Despite this overall growth, June saw a decline in shipments, which dropped by 21 percent compared to May and by 4 percent compared to June 2024. The decrease, amounting to 1.13 billion cubic meters for the month, was due to scheduled maintenance on the pipeline’s undersea section.
TurkStream, which has an annual capacity of 31.5 billion cubic meters, runs beneath the Black Sea from Russia to Turkey. Originally designed to supply both Turkey and countries in southern and southeastern Europe, it has now become the only operational route for Russian gas exports to the European market.
Serbia relies on TurkStream for its supply of Russian gas and also re-exports part of these volumes to Hungary. In 2024, gas deliveries to Europe through TurkStream increased by 23 percent, totaling 16.7 billion cubic meters. Of this amount, a record 8.6 billion cubic meters were delivered to Hungary.
