A 14.42% increase in the price of Russian gas supplied to Bosnia and Herzegovina has affected third-quarter deliveries from Gazprom Export to the state-owned importer Energoinvest, which supplies consumers in the Federation of Bosnia and Herzegovina.
The change has been linked to the commercial cost of single-supplier dependence, with the increase applying to the quarterly delivery period for the Gazprom Export supply arrangement.
Dependence on Russian gas via Serbia and Turkish Stream
Bosnia is entirely dependent on Russian gas entering through Serbia and the Turkish Stream system. Annual consumption is no more than about 250 million cubic metres, while estimated payments to Gazprom reach approximately €75 million a year.
The gas enters at Šepak and moves through infrastructure built almost fifty years ago towards Sarajevo and central Bosnia.
If the 14.42% increase were applied to the full estimated annual bill, it would imply an additional cost of roughly €10.8 million. The actual 2026 impact would depend on how long the quarterly price level lasts and on future contractual revisions.
Southern Interconnection proposal and LNG access via Krk
The Federation is promoting the Southern Interconnection, intended to connect Bosnia with Croatia and provide access to the Krk LNG terminal. The stated rationale is that a second route would reduce one supplier’s ability to set price and contractual conditions.
The commercial case depends on demand and financing assumptions because Bosnia’s total gas demand is modest compared with capacity typically required for a new international pipeline. Construction costs would need recovery through tariffs paid by a limited consumer base unless the route draws new industrial demand, gas-fired power generation or transit volumes.
Long-term LNG supply arrangements would also be required, since access to Krk does not automatically translate into cheaper gas. Bosnia would pay for the LNG commodity, terminal capacity, Croatian transmission, the interconnector and its domestic network.
Governance, entity-level contracts, and tariff design
The project would require a governance model able to operate through political change, including settled arrangements on ownership, regulated tariffs, capacity allocation, procurement rules and cross-entity access before lenders assess it. Dependence on grants without a durable operating structure would postpone rather than resolve the underlying issue.
Energoinvest in the Federation and Gaz-Res in Republika Srpska maintain separate supply relationships. Republika Srpska has extended its agreement with Gazprom on what it describes as preferential terms, although detailed pricing has not been disclosed.
A national diversification strategy is difficult when the two entities pursue different commercial and geopolitical approaches. The delivered price under an alternative route would also depend on utilisation levels and contracting terms.
Potential demand growth from gas-consuming investments
Industrial policy is described as part of the solution through new gas-consuming investments that could improve utilisation. Options include district heating, flexible electricity generation or manufacturing, provided they remain compatible with Europe’s decarbonisation direction.
The pipeline designed today would need to avoid becoming an underused asset before its debt is repaid. This requirement links utilisation expectations to investment timing for new end-use demand across Bosnia.
Pricing exposure under existing supply arrangements
Bosnia’s current dependence gives Gazprom substantial pricing power under the existing supply structure. The Southern Interconnection is expected to reduce that exposure only if physical routing is supported by transparent contracts, sufficient demand and a regulatory framework accepted across the country.
