Scotland’s leading climate coalition has demanded an immediate moratorium on hyperscale data centres, warning the huge server farms could swallow more electricity than the entire country uses at peak winter demand.
Stop Climate Chaos Scotland (SCCS) says proposed projects already in the pipeline would need up to 5,249MW of power, far exceeding Scotland’s winter peak of around 4,000MW. Campaigners say approving them risks wrecking the nation’s climate targets and pushing up energy bills for ordinary households.
One Big Project Already Rejected in Edinburgh
City of Edinburgh Council threw out a 213MW data centre planned for the Gyle area earlier this month. That single site would have used as much electricity as nearly 250,000 homes.
Councillors said the developer had failed to properly assess lifetime carbon emissions or show how the project fitted with the climate emergency. The decision has given fresh hope to communities fighting similar schemes across central Scotland.
Government Policy Called “Confusing and Contradictory”
Scottish ministers have listed “green data centres” as a national development priority in planning policy, yet they have never defined what “green” actually means.
There is no requirement for developers to prove their projects will run on renewable power or that the grid can even handle the load. Campaigners say this leaves local councils making billion-pound decisions with one hand tied behind their backs.
Dr Richard Dixon, director of Friends of the Earth Scotland and a member of SCCS, said ministers must pause all hyperscale applications until proper rules are in place.
“We keep being told data centres are the future, but nobody has explained how we power them without burning more fossil fuels or driving bills through the roof,” he said.
The Numbers Are Staggering
Here are the power demands of known hyperscale projects already proposed or in planning across Scotland:
- Greengairs, North Lanarkshire: up to 1,800MW
- Millerhill, Midlothian: up to 600MW
- Westfield, Falkirk: up to 900MW
- Gyle, Edinburgh (rejected): 213MW
- Several others in early stages: combined extra 1,736MW
Total potential demand: 4,749MW to 5,249MW.
That is more electricity than Scotland’s two remaining nuclear power stations (Torness and Hunterston when running) produced together at their peak.
Jobs Promise Looks Thin on the Ground
Developers often claim hundreds of construction jobs and dozens of permanent posts. But hyperscale facilities are highly automated. The rejected Edinburgh project promised only 80 permanent jobs, fewer than a single large supermarket.
Meanwhile, the power they would take could force National Grid to keep older gas plants running longer or delay the connection of new offshore wind farms.
Communities Starting to Fight Back
From West Lothian to North Lanarkshire, local residents are organising against the server farms. They worry about constant noise from cooling fans, huge concrete buildings in green fields, and the risk of higher bills.
One Westfield resident told the BBC: “They say it will bring jobs, but most of us will just see the lights dim when these things switch on.”
What Campaigners Want Right Now
Stop Climate Chaos Scotland has written to First Minister John Swinney and leaders of all Holyrood parties demanding:
- An immediate moratorium on all hyperscale data centre applications
- A full assessment of cumulative impact on the grid and carbon targets
- Clear legal definition of what makes a data centre “green”
- Community benefit funds that actually match the scale of disruption
Becky Kenton-Lake, SCCS coalition manager, said: “We have worked for years to build a cleaner, fairer energy system. We cannot let big tech undo all that progress in one go.”
Scotland has some of the most ambitious climate targets in the world, legally binding the country to reach net zero by 2045. With every gigawatt grabbed by data centres, that goal slips further out of reach.
Ordinary Scots already face some of the highest energy bills in Europe. The fear is that hyperscale server farms will make a tough situation unbearable, while bringing almost no benefit to the communities forced to host them.
The First Minister now faces a clear choice: side with households and the climate, or open the door to big tech’s enormous power grab.
