Welcome
Marc MONTEILLER Consulting
30 years of experience dedicated to your projects.
The know-how of a large organization, the flexibility of an independent consultant.
The choice of leading companies in energy and industry

With 30 years of experience, I have built my expertise at the core of energy production and distribution, working in demanding environments such as nuclear, gas, and coal.
My career has enabled me to develop strong skills in automation, control systems, and electrical engineering, from low voltage to high voltage, as well as extensive experience in industrial maintenance: drafting and monitoring maintenance programs, managing life-cycle solutions, and overseeing retrofit projects. Throughout my assignments, I have also gained technical versatility in mechanics, water treatment, and HVAC, which I leverage in a holistic approach to facilities. Passionate about innovation and DIY, I regularly design and test prototypes and tailor-made solutions, with a focus on performance and reliability. Today, I support companies and industrial players by offering an experienced, pragmatic, and solution-oriented perspective.
