EQOS Energie

What EQOS Energie does

EQOS Energie is a Luxembourg-headquartered (with operational roots in Biberach, Germany) specialty infrastructure services company that plans, constructs, and maintains high-voltage electricity transmission networks (110 kV to 525 kV overhead lines and substations) and railway catenary systems for urban, regional, and long-distance rail. The company serves transmission system operators (TSOs), distribution system operators (DSOs), railway infrastructure companies, and energy utilities across Germany, Austria, Belgium, and Luxembourg, with major customers including 50Hertz, TenneT, ÖBB-Infrastruktur AG, Avacon, Stromnetz Hamburg, Bayernwerk, STIB/MIVB, and Energienetze Steiermark. Its three operating divisions (Bahntechnik / Railway Technology, Energietechnik / Energy Technology, and Freileitungsbau / Overhead Line Construction) deliver end-to-end scope from engineering and permitting through civil works, primary and secondary technology, installation, and commissioning.

EQOS differentiates via four proprietary software platforms (Turrix for structural analysis per DIN EN 50341, FIMS3 for line routing and terrain planning, DIMS for parcel and easement management, CREST for 3D design and collision detection) and three patented hardware products for railway catenary (TELLEUT telescopic luminaire, contactless measurement wagon, and narrow-profile mast for confined spaces). The company holds ISO 9001/14001/45001, EN-1090, ISO-3834, and VCA** certifications, operates an EN-1090/ISO-3834 certified production facility in Austria for catenary components, and runs its own training centre in Bersteland (south of Berlin). It was acquired by Eiffage SA, a CAC 40 French construction and concessions group, in October 2024. Revenue is generated through project-based contracts awarded via competitive tenders, supplemented by recurring maintenance engagements, with no standard pricing publicly disclosed.

Core offering

EQOS Energie plans, constructs, and maintains critical energy and rail infrastructure across Europe, delivered through three service divisions. Railway Technology (Bahntechnik) covers catenary systems for trams, regional, and long-distance rail; Energy Technology (Energietechnik) delivers substations from 110 kV to 420 kV plus protection and control systems; and Overhead Line Construction (Freileitungsbau) executes high-voltage transmission lines from 110 kV up to 525 kV including foundations, masting, and conductor stringing. Services span engineering, civil works, primary and secondary technology, commissioning, and ongoing maintenance for TSOs, DSOs, railway companies, and utilities in Germany, Austria, Belgium, and Luxembourg.

Product overview

EQOS Energie operates as an infrastructure services company offering three integrated service divisions: Railway Technology (Bahntechnik) for catenary systems in urban and long-distance rail, Energy Technology (Energietechnik) for substations and power generation, and Overhead Line Construction (Freileitungsbau) for power transmission lines. The company complements its core services with proprietary engineering software tools (Turrix, FIMS3, DIMS, CREST) for structural analysis, routing planning, and project management. The portfolio includes patented products for railway catenary maintenance (TELLEUT, measuring vehicles, special masts). The three core divisions share engineering expertise and operate across Germany, Austria, Belgium, and the Netherlands, serving grid operators, railway companies, and energy utilities.
