Notes

Planned capacity adds each record’s first published figure for projects not cancelled or denied; projects that publish none are never estimated. IT load is the power reaching computing equipment, so a total that includes it understates total power. Locations may be approximate where a record gives only a town or county. Counts cover tracked projects, not every data center.
