Digital Realty Begins Construction on 66MW Paris Data Center at Former Air Force Site
Digital Realty has broken ground on a major new data center campus in the Paris metropolitan area, marking a significant step in the company’s continued expansion across France. The project, designated PAR15, is the first building of the larger Dugny Digital Hub, which will ultimately comprise three facilities delivering a combined 176MW of IT capacity.
PAR15 is being developed on a former French Air Force site in Dugny, northeast of Paris, which had been vacant since 2011. The three-story facility will offer 66MW across 23,320 square meters (approximately 251,000 square feet) of space. Equans Data Centers, a subsidiary of the Bouygues group, has been appointed as the general contractor for the design, construction, and commissioning of the facility. Construction began in December 2025 and will proceed in four phases, with the first phase—offering 12MW—scheduled for delivery in 2027.
“PAR15 is a key milestone in our continued expansion in France, and selecting Equans Data Centers as strategic general contractor reflects their strong track record in delivering complex, mission-critical facilities,” said David Montrieux, regional construction director at Digital Realty. “Their ability to lead an experienced consortium and execute with a clear focus on safety, quality, and sustainability will be instrumental as we bring this new capacity online for our customers.”
At full build-out, the Dugny Digital Hub will feature three data centers: PAR15, PAR16, and PAR17. Together, they will provide more than 65,000 square meters (approximately 700,000 square feet) of IT space and 176MW of IT capacity. Digital Realty, which already operates roughly a dozen other data centers across Paris, has been pursuing development on the site since at least 2024.
Equans Data Centers brings significant experience to the project, having previously delivered 340,000 square meters (3.6 million square feet) of data hall space and more than 790MW of IT capacity. “We are proud to continue our long-standing partnership with Digital Realty in France,” said Xavier Perdereau, executive vice president of Equans Data Centers. “The proposed build-to-suit development in Dugny represents a significant milestone in Digital Realty’s European expansion and market share growth for its IT service clients. Equans Data Centers is thrilled to support this strategic initiative by delivering a high-performance, future-ready facility that meets the evolving needs of the digital economy.”
The development underscores the growing demand for data center capacity in the Paris region, a key hub for digital infrastructure in Europe. By repurposing a former military site, Digital Realty is also contributing to the broader industry trend of converting underutilized urban land into high-density computing facilities, which can help meet sustainability goals while serving the connectivity needs of cloud and enterprise customers.
