GreenYellow, a French company specialising in decentralised energy production, has launched a solar deployment programme across several Sanofi sites in France. The initiative is based on 15-year Power Purchase Agreements (PPAs), under which the company is responsible for building, financing, and operating photovoltaic carports. Three installations, located in Amilly, Ambarès and Compiègne, are either operational or nearing completion, with a combined capacity of 4.5 megawatts-peak (MWc) and an estimated annual output of 4.9 gigawatt-hours (GWh).

Initial installations at Amilly and Ambarès

At the Amilly site, in the Loiret department, seven carports now cover approximately 330 parking spaces, with an installed capacity of 1.3 MWc. Commissioned in December 2024, the infrastructure generates close to 1.5 GWh annually. It also includes a stormwater basin for rainwater management and plans for 70 pre-installed charging stations for electric vehicles.

The Ambarès site in Gironde features a similar 1.3 MWc installation across more than 350 parking spaces, also producing around 1.5 GWh annually. The project includes provision for 70 electric vehicle charging points, integrated without disrupting site operations.

Expansion in Compiègne and further development in Lyon

In Compiègne, Oise, ten photovoltaic carports are under construction and scheduled to come online in summer 2025. The site will operate with a self-consumption capacity of 1.9 MWc, aiming for an annual output of nearly 2 GWh. The deployment is part of a broader car park refurbishment project, executed without halting industrial activities.

Two additional projects are under development in the Lyon metropolitan area, though no further details have been disclosed. These initiatives illustrate a coordinated multi-site rollout led by GreenYellow, under a unified contractual model designed to streamline Sanofi’s long-term energy planning.

Mathieu Cambet, Deputy Director of GreenYellow France, highlighted the logistical complexity involved: “Delivering multi-site projects demonstrates not only our technical expertise and execution speed, but also the confidence of a leading industrial partner in our ability to operate in active sites.”
