Technical details (4)
Electric grid

Energized

Independent high-voltage substations, dedicated N+N electrical infrastructure, adiabatic cooling and diverse fiber connectivity.

Cooling system

Operational

Operator describes resilient cooling; Public sources do not establish water use or delivered capacity beyond the cited project specification.

Electric grid

Energized

Frankfurt facility with independent high-voltage substations, indirect adiabatic cooling and multiple fiber providers.

Cooling system

Operational

Cooling and efficiency claims remain limited to source-defined designs; no delivered load or water use is inferred.
