Power

Stellium states "80 MWs (designed to scale to 180 MWs) of REGO certified renewable power available" for the campus, without saying whether that is IT load, site power or grid connection, so the figure is shown but excluded from every total. The same operator FAQ states Stellium 1 is allocated 15 MW of that capacity, that halls are "3MW IT data halls", and that dual 40 MVA feeds run from the 275 kV transmission network to Data Centre 1 Sector 1. A third-party directory (Colo-X) instead describes a 32 MW campus of three 8 MW buildings, also undefined. The conflict is unresolved and no figure is treated as an IT load.
