A series of gas, electricity, petroleum and transport projects is positioning Niš as a potential southern gateway for Serbia’s energy and logistics networks, linking the country with Greece and wider Central and Southeast European markets. The most advanced project is the Serbia–North Macedonia gas interconnector, with the first pipes already delivered and construction moving toward physical pipe-laying.
Once completed, the interconnector will connect Serbia through North Macedonia to Greek gas infrastructure and LNG supplies, including the Alexandroupolis terminal. Serbia and North Macedonia are also participating in the broader Vertical Gas Corridor initiative.
Gas and petroleum links toward Greece
The planned gas connection could be accompanied by a separate petroleum-products corridor along the Thessaloniki–Skopje–Niš route.
Energy ministers have discussed the proposal, which could establish a direct connection between Serbia and Thessaloniki’s port and refining infrastructure. The project remains at an early stage, with no confirmed investment value or construction schedule. Niš already occupies a significant position on Corridor X, linking Belgrade with North Macedonia, Greece and Bulgaria. The city is also part of plans involving EPS, Srbijagas and SOCAR for gas-fired electricity generation, adding an energy-production component to the emerging infrastructure network.
Freight infrastructure adds to southern connectivity
The development of energy infrastructure coincides with the recently established Egypt-Balkans freight corridor, which runs through Thessaloniki, Sofia and Niš. Together, the projects create a wider north-south infrastructure pattern around the city, connecting energy and freight routes between Serbia, Greece and other regional markets. Serbia has traditionally relied heavily on northern and eastern routes for energy supplies and trade. Additional connections toward the south would provide access to Mediterranean ports, LNG terminals and regional markets, supporting greater diversification of transport and energy routes.
Infrastructure could support industrial investment
Improved gas, electricity and transport connectivity is also relevant to industrial development in southern Serbia. Reliable access to energy and logistics infrastructure is a key requirement for manufacturing, warehousing and logistics projects. Connections with Greece and Mediterranean supply chains could strengthen the position of Niš and the surrounding region for such investments.
Not all of the planned infrastructure is at the same stage of development. The proposed petroleum-products pipeline still requires feasibility analysis, commercial justification and financing, and there is no confirmed construction timetable. The gas interconnector, power-generation plans and freight routes are nevertheless forming a broader infrastructure cluster around Niš, bringing together gas, electricity, refined fuels, road and rail connectivity along routes between Central Europe and the eastern Mediterranean.
