Investment details and location
Jiangsu Reliance Energy Tech plans to invest €100.5 million in a battery factory in Serbia, described as its first overseas production site. The project is linked to Reliance Energy selecting Serbia for the plant. A framework agreement has been signed with Serbian authorities for the facility.
The plant is set to be built in the high-tech zone of Inđija, northwest of Belgrade. The agreement covers the establishment of the production site under terms set with Serbian authorities.
Battery products and market positioning
The factory will produce advanced batteries intended for drones, humanoid robots, unmanned vehicles, power tools and household appliances. The investment is positioned outside the utility-scale battery energy storage market. It is described as part of a broader battery technology supply chain.
The project is also presented as aligning with Serbia’s efforts to move beyond conventional automotive and electrical manufacturing. Serbia is targeting sectors connected to automation and artificial intelligence hardware, alongside advanced energy systems.
Broader industrial context for Chinese investment
Over the past decade, Serbia has attracted a growing number of Chinese industrial investors. Earlier activity was concentrated in mining, steel, automotive components and infrastructure. More recent projects have expanded into electric-vehicle components, robotics and high-tech manufacturing.
Reliance Energy’s decision to place its first overseas factory in Serbia is described as using the country as a production base serving both European and wider regional markets.
Demand drivers across mobility, robotics and automation
The investment comes as battery demand expands across multiple sectors. Electric mobility remains the largest global driver, while demand from drones, robotics and industrial automation is growing rapidly.
This shift supports a market for cells and battery packs with performance characteristics that differ from those used in passenger cars or grid storage .
Local value chain considerations and cluster building
For Serbia, the economic impact depends on how much of the production chain is eventually localised. Battery assembly alone is described as providing less value than manufacturing that includes cells, battery-management systems, electronics, testing and engineering.
A deeper local supplier base could strengthen Serbia’s position in other advanced manufacturing segments . The project may also complement investments in autonomous systems and robotics already announced for the Inđija area.
Energy system factors and sustainability requirements
Energy availability is identified as another factor for battery manufacturing. The process can be electricity-intensive, particularly when production includes cell manufacturing rather than pack assembly.
Serbia is expanding renewable generation, battery storage and transmission infrastructure while attempting to reduce long-term dependence on lignite. Industrial investors increasingly consider both electricity price and carbon intensity when choosing European production locations .
The relevance of those considerations may increase as EU carbon and sustainability rules influence supply chains even outside formal CBAM-covered sectors .
Implications for Serbia’s manufacturing depth
The investment has implications beyond its €100.5 million value. If completed as planned, Reliance Energy’s plant would add another element to Serbia’s effort to position itself between Asian battery technology suppliers and European industrial demand.
The key question is whether the project develops into deeper manufacturing or remains primarily an assembly facility . For Serbia, that distinction will determine whether the investment becomes a standalone factory or supports a broader battery and advanced-technology supply chain.
