Your energy transition partner

Unique expertise on the energy market and regulation since 2007

The GreenYellow model is based on a disruptive idea: to enhance unused spaces of our clients by installing solar panels, and focus our development on green and local energy.
Since then, we have expanded our expertise to become the energy partner for businesses and institutions and we continue to expand internationally and to diversify our customer base.



“To face energy challenges, decision-makers should no longer have to choose between economic and ecological benefits. With GreenYellow, their energy transformation becomes both profitable and responsible.”

Otmane Hajji, President of GreenYellow

Our company has grown at a brisk pace. The change in shareholding with the arrival of Ardian Infrastructure as a majority shareholder provides the company with the means and support necessary to pursue its ambitions:

  • Accelerate through external growth, assets and complementary companies.
  • Become a long-term operator, owning and operating its own assets.
  • And to expand its geographical coverage, with a strong acceleration in Europe within 5 years.
