Serbia is moving its strategic gas infrastructure programme from planning toward execution after the government said the World Bank approved financing worth about €175 million, providing multilateral backing for a broader investment programme designed to remove domestic transmission bottlenecks and diversify the country’s gas supply routes.
The first phase centres on construction of the 62-km Trupale–Pojate high-pressure pipeline, extending Serbia’s gas network north from the Niš area and creating additional capacity to move gas arriving through the Bulgaria-Serbia interconnector deeper into the domestic system.
The project is also intended to prepare Serbia for increased flows from a planned interconnector with North Macedonia, which could eventually give the country additional access to LNG terminals and the Southern Gas Corridor through Greece.
The financing is significant beyond the pipeline itself.
The World Bank programme is structured in three phases covering new transmission infrastructure, compressor capacity, underground gas storage and institutional reforms intended to bring Serbia’s gas market closer to EU rules.
For Serbia, the result could be the most substantial restructuring of its gas infrastructure in decades.
Trupale–Pojate tackles an internal bottleneck
Serbia has spent years developing new external supply routes, but diversification has limited value if gas cannot be efficiently transported through the domestic network.
That is the problem the Trupale–Pojate section is designed to address.
The pipeline will include metering, regulation, safety and SCADA systems and increase inland transmission capacity from southern Serbia.
It should allow greater utilisation of the Bulgaria-Serbia interconnector, which gives Serbia access to gas from Azerbaijan and potentially LNG arriving through Greek terminals.
The planned North Macedonia interconnector would add another southern route.
Serbia’s diversification strategy is therefore increasingly shifting from simply building border connections toward creating the internal infrastructure required to use them commercially.
That distinction matters for industrial consumers.
Additional supply routes only create genuine competition if traders can transport sufficient volumes between entry points, storage facilities and major consumption centres.
Greater internal capacity could eventually give Serbian industrial buyers more flexibility between Russian pipeline gas, Azerbaijani supplies and LNG-linked volumes.
Gas remains part of Serbia’s power strategy
The programme also has an electricity-market dimension.
Serbia plans substantial additions of solar and wind capacity during the remainder of the decade. Variable renewable generation will increase the need for flexible generation, storage and stronger regional electricity interconnections.
The government sees gas-fired generation as one potential source of that flexibility.
Serbia has already discussed new gas-fired capacity with international partners, including SOCAR, while the planned Niš combined-cycle project has been positioned as part of the country’s longer-term transition from coal.
A stronger gas network would make such investments easier to supply.
But it also creates a strategic tension.
Gas plants can provide dispatchable electricity when wind and solar output falls, but new pipelines and power stations have operating lives extending well beyond 2040, when European climate policy is expected to require substantially lower fossil-fuel consumption.
That makes utilisation rates critical to bankability.
A gas pipeline designed primarily around existing industrial and household demand carries a different long-term risk profile from infrastructure whose economics depend on substantial growth in future gas consumption.
World Bank financing changes the investment equation
Multilateral financing materially improves the project’s position.
Large transmission projects require long construction periods and generate returns over decades. Access to development-bank financing can lower funding costs and provide institutional discipline around procurement, environmental assessment and project implementation.
The World Bank programme also goes beyond physical construction.
It includes support for the Ministry of Mining and Energy, Gas Infrastruktura, Transportgas Srbija, Srbijagas and the Energy Agency, covering governance, regulation, operational efficiency and financial sustainability.
Those reforms may ultimately prove as important commercially as the pipeline.
Serbia’s gas market remains dominated by state-controlled infrastructure and long-term supply relationships. Greater transparency over network access, tariffs and system operation would make the market easier for alternative suppliers and traders to enter.
That could gradually turn physical diversification into commercial diversification.
Storage becomes the next strategic asset
Later phases of the programme envisage additional transmission infrastructure and underground gas storage.
Storage has become more valuable since Europe’s 2022 energy crisis demonstrated the importance of inventories in protecting consumers against supply disruptions and extreme price volatility.
Serbia currently relies heavily on Banatski Dvor and storage arrangements outside the country.
Additional domestic capacity would provide greater seasonal flexibility and reduce exposure to interruptions in individual import routes.
It could also strengthen Serbia’s potential role in the regional gas market.
With connections toward Bulgaria, Hungary and eventually North Macedonia and Romania, Serbia could increasingly function as a transit and balancing market between central and southeast Europe rather than simply as an end consumer.
But that opportunity depends on infrastructure, storage capacity and market rules developing together.
Climate-finance dispute will continue
The World Bank involvement has also attracted opposition.
A coalition including CEE Bankwatch, WWF Adria, the Belgrade Open School and RERI urged the World Bank board to defer the project, arguing that financing additional gas infrastructure risks locking Serbia into fossil-fuel consumption while the EU is moving toward electrification and renewable energy.
The groups had cited a proposed IBRD commitment of about $195.5 million.
Serbia’s Energy Ministry rejected that interpretation.
It argues that the programme should be considered infrastructure modernisation rather than an incentive for higher fossil-fuel consumption and says the project has been prepared under World Bank procedures including economic, environmental and social assessments and consideration of alternatives.
The ministry also argues that stronger infrastructure is necessary to diversify supply and provide system flexibility during the energy transition.
That disagreement will remain relevant even as construction advances.
The commercial question is increasingly not whether Serbia needs greater energy security, but how much new gas infrastructure will remain economically utilised as European energy demand becomes progressively less carbon intensive.
Diversification now depends on infrastructure
For Serbia, however, the immediate energy-security argument is straightforward.
The country remains heavily exposed to Russian gas even after opening the Bulgaria interconnector and beginning purchases from Azerbaijan.
New sources cannot fully change that structure while domestic transport and storage constraints limit the volumes that can move through the system.
Trupale–Pojate is therefore less about adding another international pipeline than making existing and future international connections more useful.
That could become increasingly important as Serbia negotiates future Russian supply arrangements while simultaneously developing access to Azerbaijan, Greece and other regional sources.
The investment also arrives as Serbia faces a broader energy infrastructure cycle encompassing electricity transmission, renewable generation, pumped storage, batteries and potentially new gas-fired generation.
The World Bank-backed gas programme adds another major component.
Its success will ultimately be measured not by kilometres of pipeline constructed, but by whether the infrastructure creates genuine competition between supply routes, improves storage security and gives Serbian industry access to a more flexible gas market.
If it does, the Trupale–Pojate pipeline could become the first physical step in moving Serbia from dependence on a dominant gas corridor toward a genuinely interconnected southeast European supply system.
