The 97.5 km (Türkiye - 80 km, Azerbaijan - 17.5 km) 16-inch Iğdır-Nakhchivan Gas Pipeline was constructed to transport natural gas from Türkiye’s national grid to the Nakhchivan Autonomous Republic of Azerbaijan.
This standalone cross-border pipeline enhances regional energy security, strengthens Türkiye–Azerbaijan cooperation, and ensures a reliable gas supply to Nakhchivan, which is not connected to mainland Azerbaijan’s gas network.
Construction was led by BOTAŞ on the Türkiye section and SOCAR Midstream Gas Operations LLC on the Azerbaijan section.
The groundbreaking ceremony took place on 25 September 2023, and the pipeline was inaugurated on 5 March 2025 during an event attended by the Presidents of the Republic of Türkiye and the Republic of Azerbaijan, underlining its strategic importance.
