Putting operational excellence to work for energy transition

Our business model is based on the performance of the solutions we offer our clients, and therefore on the energy savings we help them achieve.

Our wide range of expertise enables us to be their one-stop shop for transforming their energy ecosystem, and for maintaining this virtuous circle through constant improvement and innovation to anticipate future energy revolutions.

In this way, we help derisk the technologies of tomorrow and turn them into green, sustainable and profitable investments.

Philippe Houins, Chief Operations Officer





We are an energy transition accelerator 

The development of GreenYellow is directly linked to our clients’ energy needs. Because every energy transition is unique, we begin by a holistic study of our clients’ needs to show them that we can have a positive impact on their entire business.

That's how we become their ally, their go-to agent for all their energy needs over the long term. As our solutions improve with technological developments, we share these benefits with them as part of our monitoring.

Entrepreneurship and CSR drive meaning in the workplace

CSR is a key component of meaning at work, which is a central concern of ours. Our teams skew young and are deeply committed to our corporate project! Their desire to support an important cause fuels our many individual and collective actions.

Our teams’ dynamic spirit also helps to maintain our characteristically entrepreneurial mindset. We rely heavily on training to ensure everyone can be an ambassador for the company.

The diversity of our teams is key to bringing together diverse perspectives and better responding to the global and local challenges of the energy transition.
