CRAM

What CRAM does

CRAM SAS is a privately held French energy efficiency services company founded in 1958 and headquartered in Le Havre. The company designs, builds, operates, and maintains heating, ventilation, air conditioning (HVAC), district heating, biomass, heat-pump, and mini-cogeneration systems for public and private clients across Normandy, Île-de-France, and Hauts-de-France. Its core offering is organized around three pillars: Performance Énergétique et Environnementale (energy performance contracts with guaranteed savings), Réseaux de Chaleur (district heating network design, financing, construction, and operation), and Gestion Multitechnique (multi-technical building management covering HVAC, electrical, security, and elevator systems).

The company's technology stack rests on a proprietary DataCenter built in 2015, a supervision and telemonitoring platform that delivers real-time energy consumption monitoring across 7,300 maintained installations, and a GMAO (Computerized Maintenance Management) system that coordinates 550,000 annual interventions. A 500m² prefabrication workshop in Les Mureaux produces standardized hydraulic elements, while the Résocćane joint venture with DALKIA extends district-heating capacity. Service delivery is supported by 700 employees, including 450 field technicians and 95 engineers operating on a 24/7/365 basis.

CRAM's revenue model combines long-term Energy Performance Contracts (CPE, 5-20 years) with one-time installation/construction project revenue and recurring maintenance subscriptions. Sales are executed via public procurement tenders and direct enterprise negotiations; the customer base spans local governments (Ville de Paris, Le Havre Seine Métropole, Antony), social housing providers (Paris Habitat, Immobilière 3F), industrial operators (ExxonMobil, SNCF, ENEDIS), healthcare facilities, and commercial real estate. Disclosed revenue was €220M in fiscal year 2022.
