Two Data Centres proposed to provide a total of 55MW
Colt DCS has procured land in the strategic location of Les Ulis for the development of two new data centres: Colt Paris 5 & 6. This site is the second parcel of land acquired in the Les Ulis commune (Les Ulis 2), and is located in close proximity to our operational Colt Paris South West Data Centre.
The Colt Paris 5 Data Centre has been designed to accommodate the performance requirements of cloud and high-density AI workloads through a hybrid approach of using traditional air and liquid-to-chip cooling. In contrast, our Colt Paris 6 Data Centre is designed to serve the colocation requirements of the large enterprise market.
To ensure power availability, 85MW has been secured through a contracted agreement at the Les Ulis 2 site.
