Solar energy comes into stock at Altarea: GreenYellow deploys 22 MWp of photovoltaic projects with energy storage on logistics sites in Bollène and Puceul
GreenYellow, a major international player in the decentralized energy transition, is supporting Altarea, France’s leading low-carbon urban transformation company, in the design, financing, construction, and operation of large-scale photovoltaic projects on two logistics platforms located in Bollène (Vaucluse) and in Puceul (Loire-Atlantique).
Developed under 30-year PPA-type contracts, the investment is entirely supported by GreenYellow, allowing Altarea to benefit from a turnkey solution, without the need to mobilize equity.
This 22 MWc solar partnership illustrates an ambitious response to regulatory requirements, a strong commitment to CSR, and a lever for sustainable economic performance for Altarea. Together, the two partners are deploying a local, sustainable, and competitive solar energy in support of the energy transition across the regions.
A XXL SOLARIZATION AT THE HEART OF STRATEGIC LOGISTICS HUBS
These solarization projects are part of a broader strategy:
- In Bollène – 260,000 m² of logistics real estate undergoing industrial change
Located at a strategic junction of the European logistics network, with immediate access to major highways, the Bollène logistics park lies at the heart of a regional reindustrialization dynamic.
It will host several major photovoltaic installations deployed by GreenYellow:
- On the first site, a 9.6 MWp rooftop solar plant in grid injection will generate over 12 GWh/year, equivalent to the electric consumption of more +5,400 inhabitants, and will help avoid 461 tons of CO₂ emissions per year. Solar carports covering around 180 parking spaces will produce 870 MWh/year from 612 kWp installed, reducing 34 more tons of CO₂ annually.
- The second site will feature a 7.2 MWp rooftop solar plant, also grid-connected, with an expected annual production of 9.2 GWh, equivalent to the consumption of +4,100 inhabitants, and an avoided emission of 360 tons of CO₂. This building will also host a 400 kWp solar system in full self-consumption, providing 510 MWh/year of on-site production. The car parks will be equipped with 1 MWp of solar carports, covering approximately 20 truck bays and 170 light vehicle spaces, generating 1.3 GWh/year – enough to supply 585 inhabitants and prevent an additional 50 tons of CO₂ emissions annually.
- In Puceul – A high-performance logistics platform in the heart of the Grand Ouest
Sur un site de 30 000 m² situé à proximité de la métropole nantaise et des axes logistiques de l’Ouest, le projet prévoit l’installation d’une centrale photovoltaïque en toiture de 3 MWc, connectée au réseau.
Sa production est estimée à 3 GWh/an, soit l’équivalent de la consommation de +1 300 habitants, avec une économie carbone de 194 tonnes de CO₂/an.
ENERGY STORAGE: A DRIVER OF FLEXIBILITY AND PERFORMANCE
The entire solar installation in Bollène will be coupled with a 4 MWh energy storage system (BESS).
This system will enable:
- the smoothing of production and grid injection peaks,
- d’optimiser l’autoconsommation,
- and enhanced grid flexibility.
It provides a concrete solution to the challenges of integrating renewable energy into the energy mix, ensuring electrical stability and resilience.
A REGULATORY AND STRATEGIC RESPONSE
These projects provide a direct response to the APER law, which requires the solarization of rooftops larger than 500 m². Altarea goes beyond mere regulatory compliance by fully leveraging the potential of its logistics real estate assets. By producing clean energy locally while generating additional income in the form of rent, the group reaffirms its long-term strategy in favor of low-carbon logistics real estate.
A SHARED VISION OF THE ENERGY TRANSITION
Philippe Lauzanne, National Operations Director at Altarea, explains: “We wanted to go beyond mere regulatory compliance by committing our sites to an ambitious and transformative energy transition. Altarea positions itself as a committed player alongside local communities, balancing economic development, job creation, and decarbonization. With Greenyellow, we’ve found a partner capable of delivering efficient, tangible solutions that are fully aligned with our long-term vision for logistics real estate.”
Mathieu Cambet, Deputy General Manager of GreenYellow France, adds: “This project developed with Altarea reflects our vision: to design comprehensive, local, and sustainable energy solutions.
By combining solar production – whether for grid injection or self-consumption – with energy storage under a long-term contract, we address our clients’ economic, environmental, and regulatory challenges.
It is precisely this type of structuring partnership that will accelerate the decarbonization of major real estate portfolios, by delivering energy performance at the heart of local authorities.”
A BENCHMARK FOR DECENTRALIZED ENERGY PRODUCTION
The logistics site in Puceul will be operational by the end of 2025.
The contract for the first warehouse in Bollène was signed in January 2024, followed by the second in March 2025. The full commissioning of the Bollène installations is scheduled for the first half of 2027.
Due to their scale, technical complexity, and integrated approach, these solar projects are becoming a national benchmark for decentralized energy production in the logistics sector. They demonstrate that it is possible to combine industrial competitiveness with optimized carbon footprint management, within a virtuous, replicable, and sustainable approach.
