What SDEL Transport does

SDEL Transport is a French electrical-integration contractor specializing in transport infrastructure, operating as a wholly-owned establishment of SDEL INFI (a SAS with €1,008,000 capital, registered in Nanterre) within the VINCI Energies division of VINCI Group. Founded in 2000 (with lineage tracing to the 1980s SDEL Equipement de la Route that built the original SIRIUS system) and headquartered in Viry-Châtillon, the company employs 46 collaborators and generated €16M in revenue for 2025. Its activity is organized around three core verticals: underground parking electrical systems, highway equipment integration, and highway tunnel safety/electrical systems — supplemented by energy/electromechanics, automation/supervision (GTC), and equipment integration capabilities.

Technically, SDEL delivers HT/BT power distribution, LED lighting with DALI intelligent control (delivering up to 80% installed-power reduction and 2.5x fewer luminaires versus legacy sodium), video surveillance with Automatic Incident Detection (DAI), fire safety systems (SSI/SDI), variable message panels (PMV) tied into the DIRIF SIRIUS traffic management platform, and EV charging infrastructure (IRVE) certified up to 400 kW DC. The company acts frequently as lead contractor (mandataire) in multi-company groupings, coordinating civil, electrical, ventilation, and structural partners on complex live-traffic projects such as the Antony-Fresnes A86 tunnel (€25.5M total, €11M SDEL share) and SIRIUS 3.0 (€11.5M total, €4M SDEL share).

Commercially, SDEL Transport operates a project-based B2B/enterprise-field-sales model, winning business through competitive public procurement and direct contract negotiation with major French public-sector clients (DIRIF, Ville de Paris, SNCF Réseau) and private infrastructure operators (INDIGO, COFIROUTE, SANEF, ADP, ELECTRA). Contract values range from approximately €244k to €12M, typically spanning 1–5 years. Revenue derives primarily from one-time construction contracts (public infrastructure) supplemented by recurring managed-services revenue via the affiliated SDEL Transport Services entity, which maintains commissioned installations such as the Duplex A86 tunnel since 2011. The geographic footprint is concentrated in Île-de-France with one LaRéférence extension to La Réunion, and pipeline visibility extends through 2026.

Core offering

SDEL Transport is a VINCI Energies company that designs and integrates electrical systems for transport infrastructure in Île-de-France, with three core activities: parking facilities (LED lighting, EV charging, fire safety, access control, video surveillance), highways (variable message signs, traffic detection, GTC supervision), and road tunnels (HT/BT power, LED lighting with DALI, ventilation control, DAI video, fire safety). The company delivers turnkey projects as lead contractor within multi-company groupings for public and private infrastructure operators.

Product overview

SDEL Transport is a VINCI Energies company providing specialized electrical infrastructure integration services for transport infrastructure in the Île-de-France region. The company operates as a unified service provider organized around three core activities: Parking Infrastructure (Parcs de Stationnement), Highway Equipment Integration (Autoroutes), and Highway Tunnel Systems (Tunnels Autoroutiers). These activities are supported by complementary technical capabilities in Energy & Electromechanics, Automation/Supervision Systems, and Equipment Integration. The company also specializes in electric vehicle charging infrastructure (IRVE), traffic management systems including the SIRIUS platform, parking guidance systems, and fire safety systems. SDEL Transport operates as a project-based construction services company rather than a software product provider, delivering services from design through installation to maintenance.
