Colt Paris 5 and 6 Data Centres is tracked as its own facility within Colt’s Paris platform. The profile separates the 85 MW site power contract from facility IT capacity and retains the operator-published individual facility boundary. Tenant utilization, contract pricing and undisclosed project financing remain outside the verified public record.
