Serbia is advancing its energy diversification strategy through a planned gas interconnector with North Macedonia, which is often portrayed as a significant step towards securing new gas supplies. This initiative is politically framed as a southern gateway to alternative energy sources, aligning with broader European objectives for energy diversification. However, the reality of this southern corridor presents a range of structural, commercial, and geopolitical challenges that raise critical questions about its effectiveness in mitigating Serbia’s supply risks.
The proposed Serbia–North Macedonia gas pipeline aims to link Serbia’s transmission system with the southern Balkan gas network, facilitating indirect access to infrastructure in Greece and Turkey. This connection theoretically allows Serbia to tap into gas supplied via the Trans Adriatic Pipeline (TAP), LNG terminals in Greece, and volumes transiting through Turkey from the Caspian region. Nevertheless, Serbia’s position at the downstream end of an already heavily utilized corridor complicates its ability to secure stable and predictable gas supplies.
A significant limitation of the southern corridor is the availability of gas volumes. TAP was primarily designed to transport Azerbaijani gas to Italy and lacks the capacity to meet large incremental demands across the Balkans. As demand increases in neighboring countries such as Greece and Bulgaria, the volume of gas that can realistically flow northward to Serbia becomes uncertain. In this competitive landscape, Serbia faces challenges not only from regional demand but also from EU member states that typically possess greater regulatory advantages and priority access.
Transit dependency further complicates Serbia’s energy security. Gas imported from North Macedonia will depend on consistent flows through various jurisdictions, each governed by distinct regulatory frameworks and tariff regimes. This reliance introduces multiple potential friction points, including regulatory bottlenecks and capacity allocation disputes. Even minor disruptions or tariff changes along the route could significantly impact gas prices in Serbia, especially during peak winter demand periods.
The cost structure associated with the southern corridor warrants careful consideration as well. Gas transported through this route generally incurs higher transportation and system charges compared to shorter pipelines. These costs accumulate as gas traverses multiple transmission systems, each imposing regulated fees. While manageable under low price conditions, these expenses can escalate during market stress, raising concerns for Serbia’s industrial sector, which is sensitive to input cost fluctuations.
Another critical aspect is upstream concentration in gas sourcing. Although the southern corridor is often characterized as diversified, much of its gas originates from a limited number of suppliers, primarily Azerbaijan. This concentration does not equate to true diversification; rather, it exposes Serbia to risks associated with reliance on a single upstream producer for negotiations and pricing leverage.
Turkey’s role as a transit hub adds another layer of complexity to Serbia’s energy landscape. As Turkey positions itself as a regional gas broker—balancing imports from various sources including Russia and LNG suppliers—the transparency of gas purchases for Serbia diminishes. The aggregation of gas may obscure details regarding origin and pricing components, complicating long-term availability assurances.
Moreover, competing strategic priorities among regional players further impact Serbia’s situation. For both Greece and Turkey, the southern gas infrastructure aligns with national strategies emphasizing domestic security and export revenues. Consequently, Serbia risks becoming a passive consumer without substantial control over upstream resources, particularly during tight market conditions where power dynamics shift unfavorably.
From a resilience standpoint, while the southern corridor enhances route diversity, it does not inherently improve market options unless combined with flexible contracting mechanisms and storage access. Without the ability to leverage multiple hubs or store gas during lower price periods, Serbia remains vulnerable to short-term market volatility.
In conclusion, the Serbia–North Macedonia interconnector should be regarded as a conditional option rather than a definitive solution for energy security. Its effectiveness hinges on how well Serbia integrates this infrastructure into a comprehensive strategy encompassing diverse supply routes and contractual arrangements. When utilized strategically, it has the potential to bolster resilience; however, overreliance could entrench Serbia within a complex transit framework characterized by limited control and heightened cost exposure.
