Figures by the European Union’s statistical office (Eurostat) showed that supply of natural gas from Iran to Turkey rose by 70% year on year in October.
Eurostat figures indicated that Iran has exported 671 million cubic meters (mcm) of natural gas to Turkey in October.
Iran had supplied 395 mcm of gas to Turkey in October 2021, said the EU agency.
Iranian exports accounted for 21% of the total foreign gas supply delivered to Turkey in October, according to Eurostat figures.
Total Iranian gas exports to Turkey reached 7,751 mcm in the 10 months to October, down slightly from the same period last year when supplies had topped 7,785 mcm, the figures showed.
Iran is one of the three main suppliers of natural gas to Turkey along with Russia and Azerbaijan. A 25-year gas supply contract between the two countries is expected to expire in 2026.
Tehran and Ankara have started initial talks for a new contract that could allow Turkey to significantly increase its gas imports from Iran.
Reports have suggested Iran could tap Russian gas supplies under swap or purchase arrangements to boost its gas exports to Turkey.
That comes as Russia has been looking for new customers for its gas since earlier this year when its exports to Europe declined because of the military conflict in Ukraine.
