Whether to its capital or to its projects’ capital, the Group welcomes investors from family offices who share a common view, namely investing long-term in projects that have meaning - renewable energies and the energy transition in general - from a wealth perspective.

As a stakeholder committed to the energy transition, Smart Energies develops, finances, builds, and operates renewable energy production sites in Europe and Africa using solar, hydraulic, and biogas resources in the regions.
