August 01, 2025 [Reuters]- Russian energy giant Gazprom’s average daily natural gas supplies to Europe increased by 37% in July from a month earlier when maintenance work reduced them, Reuters calculations showed on Friday.

Turkey and the TurkStream undersea pipeline 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 51.5 million cubic metres (mcm) per day in July from 37.6 mcm per day in June.

That was 4.7% more than July 2024 when they stood at 49.2 mcm.

Total Russian gas supplies to Europe via TurkStream stood at around 9.93 billion cubic metres (bcm) in the first six months of this year, compared to 9.3 bcm during the same period a year earlier, according to Reuters calculations.

Gazprom’s exports to Europe in January-July last year amounted to 18.3 bcm, a figure which included volumes transited through Ukraine.

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 and 180 bcm.
