Built on coalfields.

Europe's AI capacity is rising where heavy industry used to stand. The pattern is no accident, and it tells you where the next campus will land.

Look at where Europe's big data centre projects actually sit, and a pattern appears that no press release spells out: the AI buildout is colonising the continent's industrial past.

QTS's Cambois campus (planned as ten data centre buildings of 72MW IT each per the architect's project record; trade press reports campus power of 1.1GW) occupies land tied to the former Blyth power station in England's north-east. Microsoft's Skelton Grange campus in Leeds sits on a demolished power station. In Germany, Microsoft chose the Rheinisches Revier, the lignite region between Cologne and Aachen that is phasing out coal, for a three-town cluster. France's largest single announcement, Data4's 700MW Escaudain campus, is a EUR 5bn conversion of the Parc des Soufflantes ironworks site in the Nord coalfield, and the same developer is circling the former Cambrai-Epinoy airbase up the road.

The list keeps going. Sweden's self-styled biggest data centre, EcoDataCenter's Kvarnsveden campus, is rising on a closed paper mill. Vantage bought Ford's old engine plant in Bridgend. Microsoft's Newport site was a radiator factory. Even Google's Hanau campus began life as a civil defence depot.

Why industry's graveyards win

Three forces drive the pattern. First, power. A retired power station or smelter leaves behind the one thing modern data centres queue years for: heavy grid infrastructure. Substations, transmission lines and grid rights that would take half a decade to consent already exist.

Second, land and zoning. Brownfield industrial plots are large, cheap by data centre standards, and already zoned for exactly this kind of intensive use. Nobody's village green is threatened by replacing a demolished boiler house.

Third, politics. In regions that lost mines, mills and production lines, a campus promising hundreds of construction jobs and decades of business rates is welcomed rather than fought. Microsoft's Rheinisches Revier groundbreaking was attended by state government; Escaudain was announced as industrial renewal. Contrast that with the green belt battles around London, where East Havering's 600MW scheme needs a special planning route to exist at all.

What to watch

If the pattern holds, the next wave of announcements will follow Europe's remaining industrial land banks: closed refineries, steelworks and generating stations with live grid connections. When a developer quietly buys one, as Vantage did in Bridgend and Microsoft just did on Finland's west coast, the planning application is rarely more than 18 months behind.
