Equinix PA12x xScale Data Center Paris France

Status: Under Construction   |   Location: 18-82 Rue de Montigny, 95100 Argenteuil, Paris, France

Project Overview

The Equinix PA12x Paris xScale Data Center is a purpose-built hyperscale digital infrastructure development located at 18–82 Rue de Montigny in Argenteuil, within the Paris metropolitan area, France. Developed by Equinix, Inc. through its global xScale joint venture with GIC Private Limited, the facility is designed to meet the multi-megawatt capacity and high-density computing requirements of major cloud providers, AI companies, and enterprise platform operators. Covering a campus footprint of 17,116 square meters, PA12x comprises three primary infrastructure structures: a central operations building, a dedicated backup generator facility, and an electrical substation. This configuration supports the development of a purpose-built environment for demanding hyperscale workloads.

PA12x is designed to accommodate high-density rack configurations and advanced liquid cooling systems, which can help manage the thermal demands associated with AI computing and other intensive workloads. Its planned integration with Equinix’s Paris International Business Exchange ecosystem, including PA2, PA3, PA7, and PA10, through direct high-speed fiber routes is intended to provide access to a broad interconnection environment. Equinix Fabric will support software-defined connectivity between participating cloud platforms, network providers, and enterprise infrastructure, helping customers build flexible hybrid and multicloud architectures. The project also incorporates stated sustainability targets, including a design Power Usage Effectiveness (PUE) of 1.37 and contracts for 100% renewable energy coverage. These measures reflect the growing importance of energy efficiency and power sourcing in large-scale data center development.

Argenteuil’s position within the Paris metropolitan area places PA12x within a major European market for cloud services, enterprise technology, and digital interconnection. Its relationship with Equinix’s wider Paris network could help hyperscale customers connect large computing deployments with existing enterprise and telecommunications ecosystems. The facility is also intended to serve evolving requirements for AI infrastructure and regional data hosting, subject to applicable regulatory and service arrangements. Construction is progressing, with commercial commissioning targeted for Q2 2026, according to the supplied information. Overall, PA12x represents an expansion of Equinix’s hyperscale xScale platform in France, combining dedicated high-density infrastructure, interconnection capabilities, and defined energy-efficiency objectives to support the region’s growing digital economy.
