Masselin Energie

What Masselin Energie does

Masselin Energie SAS, founded in 1924 and headquartered in Ifs, Normandy, is a multi-technical engineering and installation firm serving professional (B2B) clients in the tertiary building sector. The company operates through 10 local subsidiary companies and ~380 employees distributed across Normandy (Caen, Cherbourg, Le Havre, Lisieux, Falaise, Saint-Lô, Saint-Maurice-du-Désert, Cormelles-le-Royal), delivering integrated solutions across electrical engineering (HT/BT distribution, LED lighting, backup power), climate engineering (HVAC, ventilation, plumbing), smart building (GTB/GTC, IoT, MicroGrid), building protection (access control, CCTV, intrusion, fire detection), and renewable energy (photovoltaic, EV charging infrastructure). The company also offers environmental-transition advisory through its GRENE service covering energy, carbon, building, and biodiversity audits.

The business model is project-based B2B delivery: design, installation, commissioning, and ongoing maintenance of building systems, with revenue split across professional installation services, recurring maintenance/managed services, and energy-transition hardware (PV, EV charging). Pricing is not publicly disclosed; engagements are quoted per project. Customer segments span retail (E.Leclerc), hospitality (Ibis), healthcare, public infrastructure (Gendarmerie Tourouvre), heritage/cultural venues (La Cité de la Mer, Abbaye de Saint-Pierre-sur-Dives), sports (Stade Michel d'Ornano), and logistics warehouses. Masselin Energie is a wholly-owned subsidiary of VINCI Energies (part of VINCI SA), with Philippe Caillere serving as Président. The company is SAS-structured with €2,715,750 registered capital, holds Ecovadis Platinum and Qualifelec RSE certifications, and is Great Place To Work certified (2023, 2025). Sales and project delivery are direct, field-led, and anchored in local proximity rather than digital channels.
