What Enertion does

Enertion Developpement SAS is a French energy performance group headquartered in Vaulx-en-Velin, Auvergne-Rhône-Alpes, operating under founder Christian Mortier. The group traces its operational roots to STI (founded 1982) and was consolidated under its current multi-subsidiary structure in 2007. It comprises four to six operating entities — STI, ESSAM, CH4NGE, TECHNI Service, DGCE, and Haut Bugey Energie (HBE) — that collectively deliver HVAC engineering, installation, maintenance, district heating network operations, and Contrats de Performance Énergétique (CPE) services across industrial, public-sector, healthcare, commercial, and residential clients in France.

The group manages an installed base of approximately 1,200 installations and operates 8 district heating networks, with disclosed annual revenue of €16 million and roughly 60 employees, including 12 engineers and approximately 30 field technicians with 35+ years of experience. Core technical capabilities span energy-audit-driven retrofitting, boiler and heat-pump deployment (including a 100% decarbonized heat-pump project via HBE), district heating network build-out, and long-term performance guarantees under CPE structures. Certifications include the BPI Excellence label (2020), Qualibat, and Certibat, and BNP Paribas Développement and BPI France are referenced as financial partners across the subsidiaries.

The business model is anchored on multi-year energy performance contracts and recurring maintenance agreements, with revenue generated primarily through CPE fees, installation margins on capex projects, and ongoing service revenue across the managed installed base. Go-to-market combines direct enterprise sales to anchor accounts (McDonald's France, GL Events, LOU Rugby, INSA Lyon, the Auvergne-Rhône-Alpes Region) with public-sector tenders and, via CH4NGE, a dedicated channel into industrial thermal-process clients. Geographic focus remains concentrated in Auvergne-Rhône-Alpes, with the recent DGCE acquisition pointing to measured expansion into adjacent basins.
