Colt DCS Hayes Digital Park (existing campus)
Colt Data Centre Services · operating · London Borough of Hillingdon
Colt DCS's existing Hayes Digital Park data centres. Colt says its approved expansion adds 97 MW and takes the campus to about 160 MW, which puts today's IT power at about 63 MW; that figure is derived from the two operator numbers, not published on its own. Mapped as operating from operator records; pin nudged from the expansion.

Source: Colt DCS: expansion adds 97MW, taking the campus to about 160MW, so about 63MW of IT power exists today (derived from the two operator figures)
The largest megawatt figure on the public record for this one site (planning docs or operator materials). It may include stages that are not built yet. Not everyday electricity use; the source sits with the number. Stated size is not electricity use.

Equivalences
No operator on this map discloses expected load factor (the share of peak power used on average), so yearly electricity figures are shown as a range, not as a known total.

81,760-143,080 homes' annual electricity
ⓘ Arithmetic and sources
81,760-143,080 homes' annual electricity (at 40%-70% load factor)
- Uses biggest size stated for this site = 63 MW.
- Assumed average load = nameplate × 40%-70%.
- Home use = 2700 kilowatt-hours/year.
- No operator discloses load factor; this is a bound, not a measurement.
