Our history

Lemon Energy was born from the idea that the least polluting energy is the one we don't consume. With their dual experience in industry and the energy sector, founder Grégory Choppinet and his partner Paul Dède have taken up the challenge of decarbonizing the industrial sector.

Believing that an optimal solution cannot be achieved by addressing problems individually, Lemon Energy combines expertise in thermodynamics, electricity and digital technology to optimize an industrial site as a whole. We advocate a pragmatic, hands-on approach that focuses on measurable results over time, rather than long-term theoretical commitments.


Lemon Energy provides highly competent services and innovations to continuously adapt to industry needs while maintaining its independence.


We want to deliver quality work that everyone can be proud of. To achieve this, we're constantly improving the way we work. We listen to our customers to find concrete solutions.


We take a step back from problems and tackle them together. We cultivate moments of conviviality and return on experience, with creative energy.


As a trusted third party for our customers and as a player in the energy transition, we respect ethical principles. These principles are based on reliability, neutrality and open-mindedness.
