These projects were fully designed, developed, financed, built, and are now operated by GreenYellow, acting as a third-party energy operator. They are part of 20-year on-site Power Purchase Agreements (PPAs), providing Legrand with a turnkey solution without any initial investment (0€ Capex). This model secures a local and sustainable supply of green electricity while offering long-term visibility on energy costs.
Now fully operational, the solar plants combine ground-mounted installations and parking solar carports, tailored to the specific needs of each site. In addition to producing green, local, and cost-effective energy, the carports provide thermal comfort for vehicles, protect them from the elements, and enhance parking spaces, while contributing to the improvement of the working environment for employees and visitors.
With an annual production of 3.8 GWh, these photovoltaic power plants cover about 7% of the annual electricity consumption of the sites involved. This is equivalent to the residential energy consumption of over 1,730 inhabitants and avoids more than 150 tons of CO₂ emissions each year. All the electricity produced is self-consumed, strengthening Legrand’s energy independence and the resilience of its industrial operations.
Deployed across three major French regions — Nouvelle-Aquitaine, Hauts-de-France, and Pays de la Loire — this program reflects Legrand's ambition to integrate concrete and local energy transition solutions on its industrial sites. The facilities involved include Verneuil-en-Halatte, Sillé-le-Guillaume, De Lattre, Magré, Chalus, Lagord, and Chabanais.
“This solar project is a concrete lever in our CSR roadmap. It reflects our commitment to significantly reducing our CO₂ emissions while strengthening our energy independence,” says David Descamps, Director of Legrand France.
“We are fully committed to supporting Legrand in its decarbonization trajectory. This project, rolled out simultaneously across several occupied sites located in complex industrial environments, highlights our ability to carry out large-scale operations while addressing local specificities. It showcases the full potential of solar self-consumption as an effective, sustainable, and competitive solution. This new collaboration also reflects the renewed trust between our two groups,” adds Mathieu Cambet, Deputy CEO at GreenYellow.
Building on this momentum, Legrand and GreenYellow are currently exploring the possibility of equipping around fifteen additional industrial sites in France, to pursue and expand their shared commitment to a sustainable and decentralized energy transition.
