NDC Vélizy

NDC Vélizy is a planned colocation data center by Nation Data Center (NDC) located at 8 Avenue Morane Saulnier, Vélizy-Villacoublay, within the Paris metropolitan area, France. This facility is designed as a modular and energy-efficient site, providing approximately 4,545 m² of IT space and 468 m² of office and technical areas.

The data center is engineered for high resilience and scalability, with a total planned power capacity of 19.86 MW, supplied via a 10.4 km underground connection. Backup power is ensured by 4 diesel generators with extended runtime capability, and redundancy is planned in an N+1 configuration.

Cooling is managed by 5 chillers featuring free-cooling capability, targeting a high efficiency PUE of around 1.2. A key sustainability feature is the integration of heat recovery systems, expected to reuse approximately 4 GWh of waste heat annually for the local district heating network.

Planned services include colocation (cabinets, cages, suites), remote hands, managed services, bare metal and GPU hosting, and public cloud interconnectivity. Mitigation measures for noise, air quality, and remediation for legacy site contamination are also planned.
