Azerbaijan overtook Russia to become Türkiye’s largest pipeline natural gas supplier in June, according to official data.

Türkiye imported around 1.01 billion cubic meters (bcm) of pipeline gas from Azerbaijan in June, data compiled from the Energy Market Regulatory Authority (EPDK) showed.

Iran was the second-largest supplier, with 883 million cubic meters (mcm), while Russia ranked third with 882 mcm.

Russia had been Türkiye’s largest pipeline gas supplier in each of the first five months of 2026. Azerbaijan, however, has ranked as Türkiye’s top supplier for June since 2023.

Azerbaijan supplied 744 mcm of pipeline gas to Türkiye in June 2023, around 997 mcm in June 2024 and 1.02 bcm in the same month of 2025.

The EPDK data showed Türkiye’s total natural gas imports fell 6.19% year-over-year to around 3.06 bcm in June.

Pipeline deliveries accounted for about 2.78 bcm of total imports, while liquefied natural gas (LNG) imports stood at 282 mcm. All of Türkiye’s LNG imports in June came from Algeria.

Despite the decline in imports, Türkiye’s natural gas consumption rose 4.59% year-over-year to approximately 2.83 bcm.

Industrial consumption accounted for around 1.09 bcm, while gas use in the transformation and conversion sector, which includes electricity generation, reached 594 mcm. Household consumption stood at 710 mcm.

Türkiye’s natural gas storage volume stood at around 5.27 bcm at the end of June. Underground storage facilities held approximately 4.97 bcm, while LNG terminals accounted for the remaining 296 mcm.
