Scotland’s 23 planned data centres and the fight over them

Data centres have become a major issue in Scotland because developers want to build at least 23 giant AI-powered facilities there, some on a scale the country has never seen. Backers argue they will bring billions of pounds and thousands of jobs; opponents worry about how big they are, how much energy they consume and how much noise they make. As BBC News reported, the result is one of the most contested planning arguments in the country.

From a 12MW site in Airdrie to gigawatt ambitions

Scotland’s existing facilities are modest. The largest is believed to be DataVita’s site in Airdrie, rated at 12MW. The hyperscale proposals now on the table sit in another category altogether, and the gap is easiest to grasp side by side.

Put simply, Chapelcross alone would offer more than 80 times the capacity of the Airdrie site. Why Scotland? Its wind farms produce enormous volumes of electricity, and part of that output goes to waste because the grid cannot carry it from where it is generated to where demand sits. Locating power-hungry servers close to that surplus is a large part of the pitch.

The economic case developers and governments make

The clearest promise comes from Lanarkshire, which the UK government has named an AI growth zone with data centres at its core. When it was unveiled in January, the headline commitments were striking.

The breakdown matters: beyond those AI posts and apprenticeships, the remaining jobs are in construction, which is why the type of employment has itself become a point of debate.

Developers also lean on Scotland’s green energy. Apatura, which is behind 10 of the hyperscale proposals, emphasises its access to renewable power and battery storage. Transparency is patchier. Some facilities are built by technology giants such as Amazon, but other developers cite commercial sensitivity when asked what their servers will actually run.

What worries campaigners

The objections fall into several distinct strands:

• Backup power. Experts warn that the centres would not run on renewables alone. When the wind drops or cloud cover cuts solar output, fossil fuel power stations may need to be switched on.
• Water. Very large facilities can need substantial volumes of water to stop servers overheating, and there is concern about what hyperscale sites would consume.
• Noise and wildlife. In the US, residents living near data centres have described a constant hum from banks of cooling fans, alongside fears that it has pushed wildlife away.
• Climate targets. The Scottish Greens and campaign groups argue that big centres could undermine Scotland’s climate goals and strain renewable supplies, and have called for a moratorium.

Those concerns apply chiefly to the hyperscale proposals rather than to the small facilities already operating.

Where Scottish government policy stands

Ministers back the investment in the Lanarkshire growth zone but have refused to impose a moratorium. Instead, they have tightened oversight in stages, according to the account republished by Yahoo.

1. August The Scottish government announced that ministers must be told of any proposed centre above 50MW.
2. September It turned down the Greens’ request to pause applications until national guidelines take effect, while requiring environmental impact assessments to be submitted.
3. By Christmas New guidance is promised; the government called it “highly unlikely” that any large data centre would win approval before then.

For now, that means the 50MW threshold captures every proposal in the table above except Airdrie, and none of the giant schemes is expected to receive consent until the promised guidance is published.
