Large data centre proposals in Scotland, from pre-application notices to live planning applications and appeals, plus the sites already operating. Each entry shows its council planning record, where one exists, and its other sources by type, so every claim can be checked against more than one publisher.
Circle area scales with MW. Hollow rings have no published capacity. Positions are approximate (town or estate level).
Proposed, in progress and stalled
Schemes from first announcement through to a lodged application, plus those under construction, refused or stalled. Most are large AI campuses still at pre-application, and together they would add many times today's operating capacity.
Operating
Data centres running in Scotland today, mostly colocation, bank and research sites in the Central Belt, Aberdeen and Dundee. Most are small; the largest, DataVita DV1 at Chapelhall, is about 24MW.

How sources are graded
Each entry lists every source we used, labelled by who published it. An entry counts as corroborated when at least two different publishers report it and at least one of them is not a campaign group or a commercial directory.

How the flags work
Red: nearest building within 100 m, 10% or more of the site in a flood zone, or a designation overlapping the site. Amber: building within 500 m, any flood-zone overlap, or a designation within 500 m. Green: none of these. Measured from the council's application site; buildings from OpenStreetMap, flood zones from SEPA, designations from NatureScot and Historic Environment Scotland.
Overview
About 24ha near Heriot-Watt's Riccarton campus. The council screened out an EIA; Scottish Ministers ruled one is required.
The developer's case

Permanent jobs per megawatt of capacity. This claim is close to the study's average for planned sites.
Construction jobs are real but temporary. Figures for "job-years", "jobs supported" or "indirect" jobs count work elsewhere in the economy, not people on site. The per-MW measure comes from the think tank Verdant; techUK says it misses jobs supported outside the site, and the UK Government calls it misleading. The Next WebResultsense
Developer estimate The developer's own figure for what it plans to spend. Not a commitment.
Modelled estimate Comes from an economic model the developer paid for. Not checked independently.
Promise only Not yet written into a legal agreement (Section 75) or a planning condition, so it cannot be enforced.
Secured Written into a signed legal agreement or planning condition.
None of these benefits is secured yet for any scheme we track. GVA (gross value added) is the economic output a scheme is modelled to add.
The opening lines summarise in our own words how the developer presents the scheme. Items marked Claim are the developer's own figures, not independently checked.
The objectors' case
The petition asks the City of Edinburgh Council and the Scottish Government to give one of Scotland's largest proposed data centres full scrutiny, and says it would take greenfield land. change.org petition
Partly matches The proposal notice boundary we measured is about 25 ha. The site could change at application stage.
The opening lines summarise in our own words how objectors present their case. Campaign claims get the same checks as the developer's figures. Petition signatures are not verified as local and are not formal objections to the council.
