What Enfrasys does

Enfrasys is a French systems integrator specializing in intelligent solutions for the operation and security of transport infrastructure, headquartered in Rillieux-la-Pape (Lyon metropolitan area), France. Founded in the 1980s and operating for over 40 years, the firm employs approximately 80 collaborators and is wholly owned by VINCI Energies, the energy and digital services arm of the VINCI Group. The company serves three primary verticals: Roads & Tunnels (DIRCE, Métropole de Lyon tunnel contracts), Public Transport & Airports (SYTRAL Mobilités for Lyon Metro, VINCI Airports at Chambéry and Grenoble), and Water & Fluvial infrastructure (VNF lock/dam automation). Enfrasys generated \u20ac13.5 million in 2025 revenue and holds Qualifelec, ISO 9001, and FNTP certifications necessary to bid on French public infrastructure tenders.

The firm's offering is organized around four technical expertise domains: custom IT systems (including Exploitation Assistance Systems, cartographic hypervisors, traffic management, and passenger information), automation and supervision (multi-vendor PLC platforms — Schneider Modicon M580, Siemens, Rockwell, GE Fanuc — paired with WinCC, Panorama, Ignition, and Cimplicity SCADA software), low-current systems (CCTV, variable message signs, emergency call networks), and high-current electrical installations up to 20kV. Proprietary technology includes bespoke software built on Angular, Java (Quarkus), PostgreSQL, NGINX, and Debian stacks deployed on Kubernetes, alongside custom hardware such as a 2.5W low-power 3G-enabled road webcam and LED tunnel lighting with DALI pilot dimming (achieving 40\u201380% energy reductions). The firm also offers a dedicated 'Offres Vertes' (Green Solutions) product line aligned with VINCI Energies' environmental commitments.

Revenue is generated through two primary streams: project-based capital works contracts (one-time installations and modernizations) and multi-year managed maintenance contracts. Sales are conducted exclusively through direct engagement with public infrastructure operators via French public procurement (RFPs, tenders, direct negotiation), with no resellers, distributors, or marketplace channels. The company is led by Charles DELUCENAY as Chef d'entreprise (CEO) and operates as an independent business unit within VINCI Energies while maintaining its human-sized company identity.
