Strategic Data Center Design Combines Advanced Technology with Environmental Stewardship

Strategically located in a pre-existing industrial building within a 120-acre designated industrial zone in Wissous, Essonne, PAR1 spans 52,240 sq. m., occupying less than 11% of the industrial zone. The facility is designed to deliver a total IT capacity of 27 MW across 10,250 sq. m. of technical space in six data halls. Currently, 4.5 MW of IT capacity is operational, supported by a robust incoming power supply of 7 MVA.

Strategically located in a pre-existing industrial building within a 120-acre designated industrial zone in Wissous, Essonne, PAR1 spans 52,240 sq. m., occupying less than 11% of the industrial zone. The facility is designed to  deliver a total IT capacity of 27 MW across 10,396 sq. m. of technical space in six data halls.  

The project is being developed in three phases.

Phase 1 received planning approval in 2020 and is now operational, delivering 4.5MW of IT capacity across 1,810 sq. m. of technical space in a single data hall. This represents 20% of the total planned development. 

Phase 2 expands the facility with two additional data halls spanning 3,310 sq. m. and providing 6.9MW of IT capacity, which at the time of writing is not yet operational. This represents 50% of the total planned build. 

Phase 3, is currently awaiting environmental authorization and planning permission, and will complete the development with three more data halls delivering 15.6MW of IT capacity across 5,276 sq. m. of technical space, completing the total planned build.
