If recycling-linked metallurgy provides Serbia with a material backbone, grid and energy infrastructure manufacturing provides execution density and demand stability. Unlike commodity industries, grid manufacturing is driven by regulated investment plans rather than market cycles. For Serbia, this translates into predictable order books and strong visibility over five- to ten-year horizons.
A Serbia-centric grid manufacturing pipeline can be segmented into four interconnected product layers: substation modules, transformer and switchgear assembly, battery-storage balance-of-plant, and cable systems, supported by a fifth layer of engineering and testing services.
Substation module fabrication is the natural anchor. A single modern HV/MV substation module contains €3–6 million of manufactured content, including steel structures, enclosures, busbar supports, control rooms, and auxiliary systems. A Serbian fabrication hub capable of delivering 15–25 such modules per year would generate €60–120 million in annual revenue, with EBITDA margins of 12–16 %. Required CAPEX is modest by industrial standards, typically €8–15 million for fabrication halls, CNC lines, coating systems, and test bays. Direct employment would be 200–350 workers, predominantly skilled trades and engineers.
Transformer and switchgear assembly adds higher value per unit. Medium-to high-voltage transformer and switchgear packages range from €0.5 million to €10 million per unit, depending on specification. A Serbian assembly and testing facility producing €150–250 million of equipment annually would require €15–30 million of CAPEX, primarily for insulation processing, test equipment, and safety infrastructure. EBITDA margins typically reach 15–18 %, and employment would be 250–450 workers, with a high share of electrical engineers and test specialists.
Battery storage balance-of-plant manufacturing is the fastest-growing layer. Containerised battery systems include steel housings, thermal management, fire-safety systems, cabling, and grid interfaces. Manufactured content per unit typically ranges from €0.5–2.0 million, excluding cells. A Serbian plant delivering 100–150 containerised systems annually could generate €120–200 million in revenue, with EBITDA of €20–35 million at margins of 14–18 %. CAPEX requirements are €10–20 million, and employment 150–300 workers.
Cable accessories and junction modules provide volume stability. Though lower in unit value, they support both transmission and distribution networks. A Serbian facility in this segment could reach €40–70 million in annual revenuewith CAPEX of €3–8 million and EBITDA margins of 15–20 %. Employment would be 120–250 workers, largely in precision assembly and QA.
The final and most scalable layer is engineering, testing, and certification. While capital-light, this segment multiplies the value of all physical products. A Serbian engineering and testing centre supporting grid projects can generate €15–30 million in annual revenue with EBITDA margins exceeding 30 %, employing 80–150 highly skilled engineers. Hourly billing rates of €80–150 remain competitive versus Western Europe while delivering strong margins locally.
Aggregated across all grid manufacturing layers, Serbia could deploy €50–80 million of CAPEX to unlock €400–650 million in annual revenue and €70–110 million in EBITDA, with direct employment of 800–1,300 workers. Export-to-CAPEX ratios exceed 7×, and revenue visibility is underpinned by regulated European grid investment.
