Iran is planning a major natural gas pipeline project that could enable it to import up to 110 billion cubic metres (bcm) of Russian natural gas annually, marking a significant development in energy cooperation between Tehran and Moscow. The proposed infrastructure is expected to be developed in phases, with the initial stage designed to transport 55 bcm of gas annually and projected to take approximately two to three years to complete.
Iranian Ambassador to Russia, Kazem Jalali, disclosed the plans following discussions between Iranian security official Mohsen Rezaei and Russian President Vladimir Putin during a meeting at the Kremlin on November 5. According to Jalali, the general principles of the proposed strategic energy corridor had already received approval during a trilateral summit involving the presidents of Russia, Iran and Azerbaijan. However, the project is yet to reach the final contractual stage, with both countries still working to agree on a gas pricing formula between the National Iranian Gas Company and its Russian counterpart.
The proposed pipeline is expected to involve Azerbaijan as a critical transit country, creating an additional natural gas transportation corridor connecting Russia to Iran through the Caucasus. This arrangement would build on existing regional pipeline infrastructure while potentially requiring the development of new transportation facilities to accommodate the proposed volumes.
In the interim, Iran and Russia are exploring alternative arrangements that could facilitate gas deliveries before the completion of the larger pipeline project. One option under consideration is a gas-swap agreement involving Azerbaijan, under which Russia would supply natural gas to northern Azerbaijan while an equivalent volume would be delivered to Iran from southern Azerbaijan. Although existing regional pipeline networks could support this arrangement, some sections would require rehabilitation, alongside technical coordination between the three countries.
The proposed arrangement reflects a broader effort by both countries to strengthen their positions in the international natural gas market. For Russia, expanding gas supplies to Iran would provide another potential export destination as the country continues to pursue alternative markets and transportation routes. For Iran, importing Russian gas could help address supply requirements in its northern regions, where access to domestic production has historically been constrained by geographical and infrastructure limitations.
Despite Iran's substantial natural gas reserves, the country continues to experience domestic supply constraints, particularly during periods of peak seasonal demand. Additional imports could therefore support its domestic distribution network and potentially create opportunities for more efficient allocation of locally produced gas to other markets.
Nevertheless, the scale of the proposed project presents considerable infrastructure and commercial requirements. Transporting 110 bcm annually would require substantial pipeline capacity, coordinated transit arrangements and long-term supply agreements. Finalising the gas pricing structure remains an immediate priority, while further details concerning the pipeline's financing, construction route and implementation arrangements are yet to be fully established.
If realised, the project could establish a significant new gas transportation corridor across Eurasia, deepen energy cooperation between Russia and Iran and reinforce Azerbaijan's importance in regional pipeline connectivity. Its eventual development will depend on the successful resolution of outstanding commercial agreements and the ability of the participating countries to translate their strategic commitments into an operational infrastructure project.
