Investment race grows as projects get bigger

Data center investment has become a new economic theme in Scotland, with the rapid rise in demand for artificial intelligence pushing energy, infrastructure and jobs to the forefront. At least 23 large-scale facilities are in planning across the country; supporters say they could attract billions of pounds in capital, while critics argue the electricity, water and environmental costs will be heavy.

At present, the largest facility in Scotland is said to be the DataVita site in Airdrie, with a capacity of 12 MW. The new hyper-scale projects on the table are far larger. If the Chapelcross site planned in Dumfries and Galloway reaches 1,000 MW, it could rank among the largest data centers in the world.

Key capacity targets

  • Chapelcross project: target capacity of 1,000 MW.
  • Auchtertool project in Fife: 600 MW capacity and a 60-hectare site.
  • The land set aside is roughly equal to 84 football pitches.

That scale has shifted the debate away from the technology inside data centers and toward the economic and physical impact of the facilities themselves. While some developers present the projects as strategic infrastructure, land use and quality-of-life concerns are also growing at local level.

Energy and water demand is changing the market calculation

Scotland’s strong wind power output is seen as a major draw for developers. However, experts stress that grid capacity can be insufficient to move generation to where it is needed, and that available surplus electricity does not mean data centers will run entirely on renewable energy.

It is said that fossil-fuel power plants may need to come online during periods of weak wind or low solar generation. Water use is also likely to rise because of cooling needs at large facilities, making it an important cost factor for the market, while the constant noise from thousands of servers and fans creates a separate risk for local communities.

Job promises and permitting uncertainty continue at the same time

The UK government has designated Lanarkshire as an artificial intelligence growth zone centered on data centers. Under the framework announced in January, £8 billion in investment and 3,400 jobs were promised, around 800 of them in AI, 50 through apprenticeships, and the rest from construction activity.

The Scottish government requires proposed facilities above 50 MW to be notified to ministers, but it has not so far accepted calls for a moratorium on large data centers. At the same time, the administration, which makes environmental impact assessments mandatory, said approval for major projects before Christmas is unlikely and that new national guidance will be published before the year-end holiday period.
