Introduction
This dataset shows the maximum observed utilisations of operational data centres identified in UK Power Networks' region.
The utilisations have been determined using actual demand data from connected sites within UK Power Networks licence areas, from 1 January 2023 onwards.
Maximum utilisations are expressed proportionally, by comparing the maximum half-hourly observed import power seen across the site's meter point(s), against the meter's maximum import capacity. Units for both measures are apparent power, in kilovolt amperes (kVA).
To protect the identity of the sites, data points have been anonymised and only the site's voltage level information has been provided - and our estimation of the data centre type - has been provided.
Methodological Approach
Over 100 operational data centre sites (and at least 10 per voltage level) were identified through internal desktop exercises and corroboration with external sources.
After identifying these sites, their addresses and their MPAN(s) (Meter Point Administration Number(s)) were identified using internal systems.
Half-hourly smart meter import data were retrieved using internal systems. This included both half-hourly meter data, and static data (such as the MPAN's maximum import capacity and voltage group, the latter through the MPAN's Line Loss Factor Class Description). Half-hourly meter import data came in the form of active and reactive power, and the apparent power was calculated using the power triangle.
In cases where there are numerous meter points for a given data centre site, the observed import powers across all relevant meter points are summed, and compared against the sum total of maximum import capacity for the meters.
The maximum utilisation for each site was determined via the following equation (where S = Apparent Power in kilovolt amperes (kVA)):
% Maximum Observed Utilisation =
MAX(SUM( SMPAN Maximum Observed Demand))
SUM( SMPAN Maximum Import Capacity)
Quality Control Statement
The dataset is primarily built upon customer smart meter data for connected customer sites within the UK Power Networks' licence areas.
The smart meter data that is used is sourced from external providers. While UK Power Networks does not control the quality of this data directly, these data have been incorporated into our models with careful validation and alignment.
Any missing or bad data has been addressed though robust data cleaning methods, such as omission.
Assurance Statement
The dataset is generated through a manual process, conducted by the Distribution System Operator's Regional Development Team.
The dataset will be reviewed quarterly - both in terms of the operational data centre sites identified, their maximum observed demands and their maximum import capacities - to assess any changes and determine if updates of demand specific profiles are necessary.
This process ensures that the dataset remains relevant and reflective of real-world data centre usage over time.
There are sufficient data centre sites per voltage level to assure anonymity of data centre sites.
