Engineering firm Mercury has been chosen to deliver Digital Realty’s next expansion phase of its Paris campus in France.

The colocation provider delivered the 19MW PAR9 facility earlier this year and will be the main contractor for the rest of the expansion at Digital Realty’s PAR10 and PAR11 sites.

Construction has already begun at the PAR10 site and is expected to launch at the end of this year. The PAR11 facility is scheduled to open in Q3 of 2025.

Digital Realty’s PAR8, PAR9, PAR10, and PAR11 sites comprise the company’s Paris Digital Park.

When complete, the Paris Digital Park will offer a combined 76MW of IT power across 39,000 sqm (420,000 sq ft) of white space.

The companies said each data center on the campus will feature a reliable power supply, efficient cooling, advanced alarm systems, and high-density racks with free cooling. All four facilities are also expected to be powered by 100 percent renewable energy.

The campus is set to have dual fiber connectivity with up to 85 network providers.

Alan Clinton, managing director of Mercury’s data centers and building service division, said: “We are excited to continue our partnership with Digital Realty and contribute to the success of the Paris Digital Park project. This partnership represents a significant opportunity for Mercury to demonstrate our expertise and drive the growth of the data center industry in Europe.”

Digital Realty first announced plans for the Paris Digital Park in April 2020 after buying Interxion for $8.4 billion.

Digital Realty has nine other data centers located in the Paris region, not part of the Paris digital park. The company is working on a new campus south of the capital in Les Ulis.

Mercury also delivered a Frankfurt data center to Global Switch last month.
