CloudHQ CDG Lisses Campus
- Planned critical IT
- 150 MW
- Updated
- Oct 29, 2026
CloudHQ’s CDG campus in Lisses markets approximately 150 MW of critical IT design, comprising two 74.4 MW buildings. A June 2025 facility inauguration does not establish full-campus commissioning. Infrastructure includes an on-site 225 kV substation, diverse fiber ducts, cooling and district-heat reuse design. A November 2022 joint release reported acquisition of approximately 137,000 m² and a heat-network investment commitment; current title and delivered heat remain unverified. Géorisques lists an authorized operating installation, with 2025 supplementary prescriptions and an inspection whose conditions and findings have not been reviewed.
