Culham AI Growth Zone data centre (Oxfordshire)
UKAEA invited expressions of interest in August 2025 from partners to build a mission-led AI data centre at its Culham campus, part of the first UK AI Growth Zone. The invitation describes about 100 MW initially with the potential to grow towards 500 MW. No partner was named in the source checked. UKAEA would first release at least 10 acres of land and its reconfigured power connections.
