What Elnos Group does
Elnos Group is a privately held energy infrastructure EPC (Engineering, Procurement, Construction) contractor headquartered in Banja Luka, Bosnia and Herzegovina, with operating subsidiaries in Serbia and Slovenia and project execution across 15+ European countries. The company delivers turnkey power infrastructure projects including hydropower, wind, and solar power plants (1,850+ MW realized, 850+ MW in execution), substations up to 400 kV (AIS, GIS, and HVDC), and high-voltage transmission lines (400 kV, 220 kV, and up to 130 kV). Beyond EPC services, Elnos designs and manufactures proprietary electrical equipment including prefabricated transformer stations (nearly 300 units delivered), electrical cabinets (4,000+ units), container substations, BESS systems, data center solutions, and the patented Uniplom plastic security seal line. The group also provides digitalization services (SCADA systems, IoT devices, and energy analytics) and serves industrial clients across steel, paper, refining, and manufacturing sectors.
Elnos generates revenue through three primary streams: (1) project-based EPC contracts as main contractor or consortium partner (e.g., the 300 MW Vetrozelena Wind Farm with Sinohydro, the 900 MW HVDC DolWin 5 with Hitachi Energy, and the 312 MW Čibuk 1 & 2 wind farms with Masdar/Taaleri), (2) direct hardware sales of manufactured electrical equipment to utility and industrial clients, and (3) professional services for SCADA integration, IoT deployment, and long-term maintenance. Customers are primarily European transmission system operators (TenneT, Svenska Kraftnät, ELES, Landsnet, 50Hertz, Amprion) and renewable energy developers (Masdar, Taaleri, Sinohydro, EFT Grupa), with go-to-market executed through direct enterprise sales, consortium participation, and subcontracting arrangements with consulting firms such as Cteam. The company has accumulated over 30 years of operating history and a reference portfolio of more than 150 completed projects across Europe.
