Urbasolar, a leader in photovoltaic solutions, began construction in October 2025 on a rooftop solar power plant at the OMEGA logistics facility, which covers an area of 136,000 square meters within the DELTA 3 multimodal platform in Dourges, northern France.
With an installed capacity of 18 MWp, including 1 MWp for self-consumption, this project—Europe’s largest single-piece solar roof—marks a significant step forward in the energy transition and reaffirms Urbasolar’s commitment to sustainable solutions.
OMEGA was designed to be a model of energy efficiency. The building consists of twelve storage units, each measuring 10,714 m², with a clear height of 11.5 meters and equipped with loading docks on two of the four facades. This new warehouse, which will accommodate up to 450 employees, is designed to meet the growing needs of domestic logistics and the decarbonization of logistics operations. This is particularly true for the PepsiCo group, which has chosen OMEGA and is set to move in by the end of September 2025.
The OMEGA construction site is managed by SPL Delta 3, the real estate developer responsible for the development and planning of the multimodal platform, which is owned by the Syndicat Mixte and the Hauts-de-France Region. As the ultimate investors, Tristan Capital Partners and Edmond de Rothschild REIM France have partnered to co-finance this project.
Thibault Ancely, Managing Director of Tristan Capital Partners, and Kristelle Wauters, Chairwoman of Edmond de Rothschild REIM France, stated: “We are proud to be part of this project, which combines innovation and sustainability. Our goal is to develop logistics infrastructure that addresses today’s environmental challenges. Our collaboration with Urbasolar is essential to maximizing this building’s energy efficiency. ”
Antoine Millioud, President of Urbasolar, added: “This project represents a major milestone in our sustainable development strategy. By integrating state-of-the-art photovoltaic solutions into modern logistics buildings, we are demonstrating that solar energy can play a key role in reducing energy costs and CO2 emissions. We are also delighted to be working with partners such as Delta 3, Tristan Capital Partners, and Edmond de Rothschild REIM France, who share our vision of a sustainable energy future. ”
“For this building, which we wanted to be a model of environmental sustainability, SPL Delta 3 did not want to limit itself to the legal minimum of 30% of the roof area equipped with a solar array. At a time when controlling energy costs is becoming essential for our clients, this strategic choice to cover the entire usable roof area with solar panels using a mix of self-consumption and grid feed-in proved decisive in marketing the building.” Emmanuel Favreuille, Director at SPLA DELTA 3
Construction of the rooftop solar power plant will be completed in two phases. This project is part of a commitment to sustainable development and innovation, demonstrating Urbasolar’s expertise in large-scale rooftop installations and reinforcing its position as a key player in France’s energy transition.
