  • Join the objectives of the energy transition law.

Robust values

  • The strong and lasting commitment to the service of a different energy production: natural, local, respectful of the environment, competitive, topical and future-oriented: geothermal energy
  • Competence, to make complex projects simple. Specialized, reliable, humane, innovative and rigorous engineering to provide customized solutions and services for a growing contribution to the development of renewable energies in heat networks, industry and power generation.
  • Trust in our employees, our partners and the one we strive daily to establish in our relationships with our customers

Entrepreneurship and teamwork

As a multidisciplinary engineer team, we share our knowledge and work collectively to realize new projects and innovate.


Because a geothermal project is complex, engaging and capital-intensive, and because natural resources are sometimes “capricious”, CFG secures its approach by promoting targeted, technical, commercial and R&D partnerships with a permanent concern of sharing and mobilization towards the goal of its customers.


CFG’s activity is managed within two technical departments:

The Technical Department “Engineering – Project Management” for studies, engineering and project management.
The Technical Department “Maintenance Monitoring Operation” for maintenance activities, monitoring of operation, sales of equipment and products (including Kits Labège).
