Aurelius Data Centre Proposal

In planning
Not published

Not verified

North Lanarkshire Β· Scotland

ILI Group

Aurelius is one of ILI’s proposed Stoics sites. ILI reports land rights, grid arrangements and entry into the planning process across the network. Site-specific IT load and annual use remain unverified here.

Data centres

Cato Data Centre, Auchtertool

In planning
600 MW

Proposed campus capacity

Fife Β· 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.

Data centres

CyrusOne LON6, Iver Heath

In planning
108 MW

Current published IT capacity

Buckinghamshire Β· England

CyrusOne

CyrusOne’s 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.

DataVita Fortis Data Centre

Operating
Not published

Not verified

North Lanarkshire Β· Scotland

DataVita

Fortis is DataVita’s 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.

Data centres

Drax AI Data Centre Proposal

In planning
100 MW

Phase-one upper bound

North Yorkshire Β· 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 Manchester

Operating

Not verified

Greater Manchester Β· England

Equinix

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

Data centres

Freeport West Lothian Data Centre Campus

In planning
250 MW

Proposed campus capacity

West Lothian Β· Scotland

Apatura

The developer’s 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.

Google Waltham Cross Data Centre

Operating
Not published

Not disclosed

Hertfordshire Β· England

Google

Google announced the opening of Waltham Cross in September 2025. The centre is part of Google’s UK digital infrastructure. Google’s corporate renewable-energy purchases do not disclose the site’s measured electricity draw.

Green Mountain LON-East

Operating
Not published

Phased capacity

Greater London Β· England

Green Mountain

LON-East is Green Mountain’s 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.

Lanarkshire AI Growth Zone / DataVita Development

In planning
Not published

Multi-site programme

North Lanarkshire Β· 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.

Data centres

Larbert Data Centre Campus

In planning
300 MW

Proposed campus capacity

Falkirk Β· 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.

Data centres

Nscale Loughton AI Campus

In planning
50 MW

IT capacity

Essex Β· 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.

Data centres

NTT Hemel Hempstead 4

Operating
12 MW

IT capacity

Hertfordshire Β· 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.

Data centres

NTT London 1, Dagenham

Operating
64 MW

Ultimate IT capacity

Greater London Β· 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.

Data centres

QTS Cambois Data Centre Campus

Enabling works
720 MW

Planned campus capacity

Northumberland Β· England

QTS

QTS’s 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.

Data centres

Ravenscraig Data Centre Campus

In planning
550 MW

Grid connection capacity

North Lanarkshire Β· 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.

Rufus Data Centre Proposal

In planning
Not published

Not verified

East Ayrshire Β· Scotland

ILI Group

Rufus forms the western part of ILI’s 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.

South Mimms Data Centre Site (formerly DC01UK)

Consented
Not published

400 MVA reservation

Hertfordshire Β· 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.

Campus connection

Greater London Β· England

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 West Two, Docklands

Under construction
33 MW

Published building capacity

Greater London Β· England

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.

Vantage CWL1 Newport Campus

Operating
148 MW

Published IT capacity

Newport Β· 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.

Data centres

VIRTUS Stockley Park Campus

Operating
112.5 MW

IT capacity

Greater London Β· England

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.

Wester Hermiston Data Centre Campus

In planning
200 MW

Proposed campus capacity

Edinburgh Β· Scotland

Apatura

Apatura’s consultation describes a 200 MW campus on land at Wester Hermiston. This is a development proposal. No current metered electricity use or operating renewable supply is reported for this project.

Data centres

Westerhill Data Centre Campus

In planning
300 MW

Proposed campus capacity

East Dunbartonshire Β· Scotland

Apatura

The developer proposes a 300 MW campus within the Westerhill Regeneration Area. Consultation and planning work are distinct from construction and operation. Published campus capacity is not a measurement of present electricity demand.

100 MW

Planned campus capacity

Berkshire Β· England

Yondr

The second building’s initial service phase was announced in April 2025. The wider 100 MW campus is delivered in phases. Initial service dates and ultimate campus capacity do not establish that every building is fully commissioned or drawing its rated load.
