What Degréane does

Degréane is a French electrical infrastructure services company headquartered in La Farlède (Var region, Toulon basin) and operating since 1927 as a wholly-owned subsidiary of VINCI Energies within the VINCI Group. The company operates through three specialized business units: Citeos (public lighting, urban dynamic equipment, EV charging infrastructure, and festive illuminations), Degréane Elec (tertiary-sector strong and weak current electrical installations for commercial buildings), and Degréane SII (high-voltage systems HTA/HTB/BT, power conversion, dock shore power, photovoltaic systems, and industrial infrastructure). Degréane employs approximately 120 people and serves defense/military clients (ESID Toulon, AIA Cuers, Base Aéronavale Hyères), local governments and collectivities, port and airport operators, and commercial enterprises across the Var region and broader France, holding the French 'Confidentiel Défense' security clearance along with ISO 9001, ISO 45001, and Qualifelec certifications.

The company's core technical capabilities span electrical distribution networks from 400V to 63kV, frequency conversion (50Hz-60Hz-400Hz) for powers ranging from 50kVA to 20MVA, and specialized shore power and dock current conversion systems originally developed for military vessels and extended to cruise ships and commercial ports. Notable proprietary competencies include port crane maintenance (20+ years of expertise), HTB/HTA electrical substations for naval bases, and integrated security systems (video surveillance, access control, intrusion detection) certified under APSAD standards. The Citeos brand membership extends the company's reach through a national network of 70 firms.

Degréane generates revenue through project-based B2B services delivered directly via specialized account managers, with custom quotes based on project scope and complexity, and multi-year maintenance contracts. Pricing is not publicly disclosed and is quote-driven. The company emphasizes minimal subcontracting to maintain quality control and operates with what it characterizes as family-business agility combined with access to VINCI Energies group resources. Distribution is entirely direct — no resellers or third-party channels — focused on the Provence-Alpes-Côte d'Azur region with deployment capabilities across France for specific clients. The company has signaled strategic expansion into electric-vehicle charging infrastructure (heavy truck and port applications), photovoltaic systems, and sustainability positioning (40% CO2 footprint reduction target by 2030; 26.32% reduction achieved in 2024).
