Serbia’s long-awaited gas interconnector with Bulgaria—celebrated as a strategic milestone that would diversify supply and reduce dependence on Russian gas—has yet to reach its full operational capacity. Months after its commissioning, industrial consumers express growing frustration over limited throughput, tariff levels and uncertainty surrounding long-term contracts.
For Serbian industry, gas remains a critical input. Chemical producers, metal processors, food manufacturers and district-heating systems all depend on affordable and predictable gas supplies. The interconnector was expected to transform the landscape by opening access to Azerbaijani gas and liquefied natural gas (LNG) via Greece. But operational bottlenecks have slowed the transition, leaving companies still reliant on traditional supply structures.
Local energy specialists, including analysts referencing serbia-energy.eu, argue that while the infrastructure is technically in place, the regulatory and contractual environment has not caught up. Transmission tariffs remain higher than industry expected. Agreements with upstream suppliers are progressing slowly. And capacity auctions have been less competitive than anticipated, reducing downward pressure on gas prices.
The Ministry of Mining and Energy insists that the interconnector is functioning and that capacity will gradually increase as market participants adjust. But large industrial consumers warn that delays undermine their competitiveness. Many have already faced higher production costs due to global gas price fluctuations. They cannot afford prolonged uncertainty or a system that does not yet deliver the diversification they were promised.
Another complicating factor is Serbia’s internal gas-market structure. Srbijagas, the dominant state company, continues to shape pricing and supply terms in ways that are not fully aligned with liberalized European models. The interconnector can reshape Serbia’s gas geography only if competitive supply dynamics emerge — a shift that requires transparent tariffs, access rules and flexibility for private suppliers.
There is optimism, however, that 2026 will bring significant improvements. New LNG capacities in the region, particularly in Greece and Türkiye, could increase competition and reduce prices. Additional Azerbaijani volumes may become available, reinforcing the strategic rationale for the interconnector. And Serbia’s broader energy diversification agenda includes strengthening storage capacity and integrating into regional balancing markets.
For now, the gap between expectation and reality remains wide. The interconnector is more than a pipeline; it is a test of Serbia’s ability to reform its energy market, attract competitive suppliers and align with European energy frameworks. Industrial consumers want results, not symbolism. Their message is clear: full capacity, lower tariffs and stronger competition are essential for maintaining Serbia’s industrial competitiveness in the years ahead.
