Fife ยท Scotland
ILI Group
The project architect describes a proposed 600 MW data centre near Auchtertool. ILI identifies Cato as part of its three-site Stoics network. Planning progress and connection rights do not establish an operating load.

Buckinghamshire ยท England
CyrusOne
CyrusOneโs current LON6 site specification gives 108 MW of IT capacity, replacing the 90 MW figure in earlier announcements. Initial capacity is targeted for 2028. Current metered demand and completed construction are not established by the announced rating.

North Lanarkshire ยท Scotland
DataVita
Fortis is DataVitaโs operating Scottish data-centre facility. The operator also markets future AI facilities and private-wire energy parks. Those development concepts are separate from the operating site and must not be counted as existing electricity demand.

North Yorkshire ยท England
Drax
Drax describes a first phase below 100 MW using a former coal-generation grid connection. This is a proposed electricity consumer at the power-station site, distinct from both Drax generation and the EGL2 converter. Later direct-generation options remain proposals.

Equinix
MA5 is Equinixโs Manchester colocation facility. Public operating information identifies the site; a verified site-wide MW capacity and annual metered consumption have not been established here.

West Lothian ยท Scotland
Apatura
The developerโs September 2026 statement identifies a 250 MW proposed West Lothian campus. Consultation material also describes onsite battery storage. No independently verified battery energy capacity or annual electricity consumption is available in this profile.

Hertfordshire ยท England
Google announced the opening of Waltham Cross in September 2025. The centre is part of Googleโs UK digital infrastructure. Googleโs corporate renewable-energy purchases do not disclose the siteโs measured electricity draw.

Greater London ยท England
Green Mountain
LON-East is Green Mountainโs Romford campus. A September 2026 announcement describes a new 14 MW customer agreement. A customer contract should not be counted as the total campus capacity or as current average draw.

North Lanarkshire ยท Scotland
DataVita / HFD Group
DataVita markets research, enterprise and hyperscale facilities within a wider development programme. This record covers the programme rather than treating advertised facility scales as an operating campus total. Individual energised loads require separate evidence.

Falkirk ยท Scotland
Apatura
A full planning application has been accepted by Falkirk Council. The developer targets initial operation in 2028 and describes a link to its consented BESS site to the north. The proposal remains subject to planning approval.
Source review: 2026-10-08IT capacity
Essex ยท England
Nscale
Nscale announced 50 MW of AI capacity, with a potential 90 MW power allocation. Its 2027 delivery target is a developer target and depends on grid availability. Announced compute capacity does not establish a live operating campus.
Source review: 2026-10-08IT capacity
Hertfordshire ยท England
NTT
The operator publishes 12 MW of critical IT load and a 60 MVA onsite substation. The redundant supply system supports resilience; its summed ratings must not be treated as a continuous electricity requirement.
Source review: 2026-10-08Ultimate IT capacity
Greater London ยท England
NTT
NTT describes 32 MW of critical IT load in the first building and 64 MW when fully built out. The larger value is an ultimate development figure. It does not show present occupation, site-wide draw or annual consumption.

Northumberland ยท England
QTS
QTSโs former power-station site is being prepared for a ten-building campus. The 720 MW figure describes its full planned capacity, not current draw. Delivery and occupation are phased.
Source review: 2026-10-08Grid connection capacity
North Lanarkshire ยท Scotland
Apatura
Proposals reuse part of the former steelworks site. Current consultation material pairs the 550 MW data campus with a 150 MW BESS. Earlier material referred to a larger battery concept, so the two versions should not be combined into one specification.

East Ayrshire ยท Scotland
ILI Group
Rufus forms the western part of ILIโs Stoics network. It is a proposed project. The reviewed developer overview does not supply site-specific metered use, IT capacity or a named renewable supply contract.

Hertfordshire ยท England
Equinix
The South Mimms development site was sold to Equinix in October 2025. The earlier developer reported planning approval and a 400 MVA power reservation. Apparent power in MVA is not equivalent to MW without a power factor, and a reservation is not metered demand.

Telehouse
Telehouse operates an established Docklands campus with a private 132 kV substation. The cited overview describes 50 MVA for that substation. This apparent-power figure must not be relabelled as IT capacity or as average consumption.

Telehouse / KDDI
Telehouse broke ground in October 2025 on West Two, targeting completion in 2028. The announcement specifies 33 MW overall building capacity and two new 132 kV substations serving the wider campus. This development is separate from the existing Docklands facilities and their historical connection ratings.

Newport ยท Wales
Vantage Data Centers
The operator markets its CWL1 campus at Newport with 148 MW of capacity. This is a campus specification, not a published average electricity load. Additional AI deployments and phased expansion should be tracked separately from current consumption.

VIRTUS
VIRTUS publishes 112.5 MW of IT capacity for Stockley Park. Cooling and other facility services require electricity in addition to IT load. Actual occupation and annual metered consumption are not disclosed by this capacity figure.
