Scotland has become a focal point in a global competition to construct hyperscale data centres driven by artificial intelligence expansion. These facilities, which process queries for services like ChatGPT and support cloud computing infrastructure, are being developed at unprecedented scale, with at least 23 major projects in planning stages across the country.
The proposed facilities represent a dramatic increase in size compared to existing Scottish data centres. Current operations such as DataVita’s Airdrie site have 12MW capacity, while new proposals include facilities with 600MW to 1,000MW capacity. One planned site at Auchtertool in Fife would occupy 60 hectares, equivalent to approximately 84 football pitches in land area. A proposed facility at Chapelcross in Dumfries and Galloway would rank among the world’s largest data centres by capacity.
Proponents argue these developments offer substantial economic benefits, citing potential investment in the billions of pounds and thousands of job creation opportunities. Lanarkshire has been designated an AI growth zone by the UK government, with initial announcements promising £8 billion in investment and 3,400 jobs. However, critics raise multiple concerns about the projects’ feasibility and impact. The Scottish Greens and campaign groups have called for a moratorium, arguing the facilities could undermine climate objectives and strain renewable energy supplies.
Scotland’s renewable energy infrastructure, particularly wind power generation, represents a key attraction for developers. However, experts caution that data centres would not operate solely on renewable sources, potentially requiring fossil fuel power stations during periods of insufficient wind or solar generation. Water consumption presents another significant concern, as hyperscale cooling systems require substantial quantities to prevent equipment overheating. Additionally, operational noise from thousands of server fans and cooling systems has prompted complaints in other jurisdictions.
The Scottish government has declined to impose a moratorium while establishing a 50MW notification threshold for proposed centres. Officials indicated new guidance would be published by year-end, with statements that approvals before the festive season were unlikely. The approach reflects balancing tensions between supporting technological advancement and addressing environmental and community concerns raised by these large-scale industrial facilities.
