- Power
- Data4 quotes campus power capacities of 250 MW each for PAR01 and PAR03 and 5 MW for PAR02, 505 MW overall, without defining the metric.
- Connectivity
- The operator says the campus connects to more than 70 telecom operators and over 150 public cloud platforms.
The operator page does not say which buildings or phases are live, so the stage is a campus-level assumption from the page treating it as an operating campus. The 505 MW figure is a power capacity of the whole campus, not a built IT load.
What we checked
- Data4 lists PAR01 and PAR03 at Nozay and PAR02 at Marcoussis on 133 hectares with 505 MW of total power capacity (metric not defined). (source)
