This report evaluates the strategic pivot of Iran towards deeper energy and logistical integration with Russia to mitigate chronic domestic supply deficits.

It examines how the International North-South Transport Corridor (INSTC) and bilateral gas transit agreements serve as fundamental mechanisms to endure Western-imposed economic constraints.

Context

On 25 March 2026, Moscow hosted the scientific-practical conference “Issues of developing the North-South International Transport Corridor (INSTC): logistical, political, economic, environmental, sanctions, and military. Iran 3.0: potential sanctions for the INSTC”.

The conference was organised ahead of the IV Astrakhan International Forum with the direct support of Alexander Mikhailovich Sharov, General Director of OOO Neftekhimtrans (RusIranExpo Group).

Among the presentations, Anastasia Nikolaevna Obukhova, researcher at the Centre for the Study of Near and Middle Eastern Countries of the Institute of Oriental Studies of the Institute of Oriental Studies of the Russian Academy of Sciences (Institut Vostokovedenija Rossijskoj Akademii Nauk), discussed Tehran’s difficulties on the path toward achieving energy sovereignty and security, while highlighting methods for monetising Iranian energy and opportunities for unlocking the country’s energy potential.

The Iranian Islamic Republic (IRI)’s primary constraint is not resource scarcity but structural imbalance between production, storage, and consumption. The Iranian energy sector, in fact, is characterised by a profound paradox: the nation holds 17.1% of global gas reserves (the world’s second-largest, comprising 32.17 trillion cubic metres) and 9.1% of oil reserves, yet suffers from systemic underinvestment and recurring nationwide blackouts. Since 2012, disconnection from SWIFT and subsequent US withdrawal from the JCPOA have restricted export diversification, forcing over 90% of oil exports toward China.

Following the US withdrawal from the JCPOA, crude exports plummeted from 2.5 million b/d in 2017 to 0.4 million b/d in 2020. This forced a strategic pivot toward petrochemicals and refined products, reducing crude oil’s share of national exports from 83% in 2007 to 49% in 2021. However, this domestic industrialisation, combined with a 1.6x increase in gas consumption over the last decade, has led to a severe energy crisis. By late 2024, the government was forced to implement nationwide blackouts to manage an electricity deficit reaching 26,000 MW during peak periods.

Domestically, the South Pars field remains the backbone of the economy, providing 70% of gas production. However, rising residential demand (consuming 48% of output) and technical pressure drops necessitate a $75 billion investment over the Seventh National Development Plan to maintain viability.

Despite a 60% increase in gas production between 2013 and 2023, nearly 94% of output is consumed domestically. Consumption is heavily skewed towards households and SMEs, constraining supply available for industrial use and export. At the same time, storage capacity remains critically insufficient, with only 3.5% of peak demand coverable through underground storage.

Iran faces a worsening energy imbalance, evidenced by nationwide blackouts in 2024 and projected gas deficits reaching over 500 million cubic metres per day by 2041. In response, Tehran is pursuing multiple strategies: infrastructure investment (notably South Pars), nuclear development with Russian support, and increased reliance on transit and regional integration via the INSTC.

Analysis

Obukhova’s data reveals a structural paradox: Iran is a resource-rich state experiencing systemic energy insecurity. This contradiction stems from three interlocking constraints (distribution inefficiencies, seasonal demand volatility, and insufficient storage infrastructure) rather than upstream production limitations.

First, the dominance of domestic consumption (94%) fundamentally limits Iran’s ability to act as an export-oriented energy power. The disproportionate share of gas consumed by households and SMEs (up to 68% in peak periods) reflects both pricing distortions and inefficiencies in demand management. This reduces flexibility in reallocating gas towards higher-value industrial or export uses, thereby constraining revenue generation and strategic leverage.

Second, the lack of adequate underground gas storage (UGS) creates acute seasonal vulnerability. Tehran can only extract 3.5% of peak daily consumption from its UGS, compared to Russia’s 45%. With withdrawal capacity covering only a fraction of peak demand, Iran is unable to buffer supply shocks during winter and summer extremes. This transforms what would otherwise be manageable demand fluctuations into systemic crises, as demonstrated by blackouts and emergency consumption measures, which triggers social instability.

Third, infrastructure and investment gaps, exacerbated by sanctions, have slowed the development of alternative energy sources, particularly nuclear. While cooperation with Russia offers a pathway to expand nuclear capacity, progress remains limited, with only marginal advances at Bushehr. Although Block 1 at Bushehr provides 1,020 MW (1.2% of capacity), a memorandum with Rosatom for 8 blocks exists. However, progress is stalled (Block 2 is only 17% complete). Consequently, the IRI remains heavily dependent on gas-fired electricity generation, reinforcing the cycle of internal consumption pressure. On the background of the current war on Iran, the US and Israel have repeatedly hit the nuclear power plant, vital for the Middle Eastern country’s future energy sustainability.

Moreover, when seeking legitimate international cooperation for its civilian nuclear programme, Tehran faces a difficult reality. While multiple nations possess enrichment capabilities, the global commercial market for the fuel cycle is dominated by a very small group of actors, and for a sanctioned state like Iran, the options are even narrower.

On a global scale, the commercial uranium enrichment market is dominated by four main entities: Rosatom (Russia), who holds the largest share of global enrichment capacity, URENCO (UK/Germany/Netherlands), Orano (France) and CNNC (China).

For the IRI, the four-player market effectively collapses into a choice between two. Tehran cannot buy fuel or technology from Western consortia. Rosatom/TVEL is the only internationally recognised partner willing and able to provide large-scale nuclear infrastructure (like the Bushehr NPP) and the associated fuel cycle services. Tehran’s own indigenous technology (such as the IR-6 centrifuges mentioned in recent IAEA reports) lacks international certification and cooperation; therefore, it would be exposed to prolonged sanctions, forcing Iran to develop its nuclear programme for civilian purposes with Moscow.

Obukhova recalled that Russia, Georgia, Armenia and Iran signed in 2015 an agreement for an electricity corridor, which has not been implemented. If Busher would be finalised as envisioned, Iran might become an energy bridge and would function as a regional hub, re-exporting Russian energy to Iraq and Turkey, thereby transforming a domestic crisis into regional leverage. Nevertheless, the damages suffered by the Busher NPP and sanctions on Iran’s nuclear programme constraints its capacity to integrate into the regional energy flow.

Within this context, the planned transit of Russian gas to Iran emerges as a strategically significant development. The near-finalised agreement (90% complete) to route gas via Azerbaijan introduces a potential external balancing mechanism for Iran’s northern regions. Even at initial volumes (2 bcm/year), the project has symbolic and infrastructural importance; at scale (up to 55 bcm), it could materially alter Iran’s energy balance.

This initiative also reflects a broader pattern of Russia–Iran energy interdependence. Moscow gains an alternative export route and geopolitical depth amid Western restrictions, while Tehran gains access to supplementary supply and transit revenues. The historical precedent of Soviet–Iranian gas cooperation reinforces the feasibility of such arrangements. Historically, in fact, the 1975 Iranian Gas Trunkline (IGAT) allowed the USSR to fulfil Western European contracts using Iranian gas.

The INSTC plays a central enabling role in this architecture. Obukhova highlighted that transit revenues from the corridor are envisaged as a key funding source for large-scale energy and nuclear projects. This creates a feedback loop: infrastructure development supports transit capacity, which in turn finances further energy expansion. Integration within frameworks such as SCO and BRICS further enhances this dynamic by reducing reliance on Western-controlled systems.

However, several vulnerabilities persist. Cybersecurity weaknesses, evidenced by repeated breaches of industrial and energy systems, pose a significant risk to infrastructure reliability. The prevalence of unsecured servers and successful attacks on SCADA systems indicate systemic exposure that could undermine operational continuity. According to data from the Shodan service, Iran is the second-most exposed country in the Middle East regarding servers with open ports (Port 3389; Port 5900).

To mitigate these risks, which have led to breaches at petrochemical plants, water treatment facilities, and oil project management systems, Iran might introduce Russian-developed defensive technologies. Obukhova suggested the APT Bug Bounty (used for stress-testing), PT NGFW (firewall) and Russian-developed secure Containers and Clouds.

Western industrial control and cybersecurity companies face restrictions in Iran, so Russia presents its software not only as a technical choice but also as a strategic imperative to safeguard INSTC nodes against digital sabotage.

Additionally, the IRI’s export dependency on a single buyer (over 90% to China) limits strategic autonomy and exposes Tehran to demand-side risks.

Another challenge for the country is the constraint imposed by Qatar. A massive $17 billion contract signed in March 2025 with domestic partners (MAPNA, Petropars) highlights an existential threat. South Pars/North Dome is a shared field. If Iran fails to maintain pressure through massive infrastructure (requiring 420,000 tons of equipment), gas will naturally migrate to the Qatari side. This project is not just about production; it is about preventing the permanent loss of sovereign resources to a Western-aligned competitor.

From a geopolitical perspective, the convergence of Russian and Iranian energy strategies, combined with INSTC development, represents a gradual shift towards a parallel energy-logistics system outside Western influence. While not yet fully realised, this system could, over time, reconfigure regional energy flows, particularly if supported by expanded pipeline infrastructure and LNG capacity.

Conclusion

The convergence between Iran and Russia in the energy and logistics domains should be understood as a forced strategic realignment driven by structural energy imbalance and accelerated by war-induced degradation. The damage to critical infrastructure, including constraints on the Bushehr Nuclear Power Plant, has reduced Tehran’s capacity to resolve its internal energy crisis autonomously, making external integration an operational necessity rather than a strategic choice.

Within an increasingly unstable Persian Gulf, where maritime routes are exposed and the Strait of Hormuz is subject to persistent disruption, the International North-South Transport Corridor emerges as a critical alternative axis, enabling Iran to partially bypass maritime vulnerability while monetising its geography. This positions Iran less as an independent energy power and more as a transit-dependent node within a Russia-linked continental system, where resilience is achieved through interdependence.

As a result, this cooperation is likely to stabilise Iran’s internal energy deficits in the short term while structurally embedding it within a non-Western energy architecture, shifting the regional balance from maritime control to corridor competition. In a destabilised Persian Gulf context, this dynamic will not reduce volatility but rather redistribute it geographically, entrenching a dual system of contested sea lanes and increasingly strategic land-based energy flows.
