June 02, 2025 [Reuters]- Russian energy giant Gazprom’s average daily natural gas supplies to Europe via the TurkStream undersea pipeline increased by 10.3% in May from a month earlier, Reuters calculations showed on Monday.

Turkey is the only transit route left for Russian gas to Europe after Ukraine chose not to extend a five-year transit deal with Moscow when it expired on January 1.

Calculations based on data from European gas transmission group Entsog showed that Russian gas exports via the TurkStream pipeline rose to 46.0 million cubic metres (mcm) per day in May from 41.7 mcm per day in April. That was down from 47.2 mcm in May 2024.

Total Russian gas supplies to Europe via TurkStream stood at around 7.2 billion cubic metres (bcm) in the first five months of this year, compared to 6.6 bcm during the same period a year earlier, according to Reuters calculations.

The company, which has not published its own monthly statistics since the start of 2023, did not respond to a request for comment.

Russia supplied about 63.8 bcm of gas to Europe by various routes in 2022, Gazprom data and Reuters calculations show. That plummeted by 55.6% to 28.3 bcm in 2024, but increased to around 32 bcm in 2024.

At their peak in 2018-2019, annual gas flows to Europe reached between 175 bcm and 180 bcm.
