Microsoft has withdrawn from a major artificial intelligence data-centre project in Loughton, Essex, creating a setback for the UK’s plans to expand its AI infrastructure.
The project, developed by British company Nscale, was presented by the UK government as the country’s largest sovereign AI data centre when it was announced in 2025. The facility was expected to become operational next year, with Microsoft planned as a major customer and anchor tenant.
The decision follows concerns over the availability of electricity for the site. UK Power Networks has told Nscale that supplying enough power to the proposed data centre may not be possible until the early to mid-2030s.
That delay has created a significant obstacle for a project designed around the rapidly growing demand for AI computing. Data centres require substantial amounts of electricity to operate the servers and specialised hardware needed for modern AI systems.
For Nscale, losing Microsoft as its publicly announced customer represents another challenge. The company has positioned the Loughton facility as an important part of Britain’s sovereign AI ambitions and is reportedly considering a potential US listing.
Nscale, however, says it remains committed to the Loughton project. The company is exploring alternative power sources and ways to accelerate the site’s connection to the electricity network. It also said its wider relationship with Microsoft remains strong, with the two companies continuing to work together on another project in Norway.
The development highlights a broader issue facing the global AI industry: building advanced computing infrastructure is not only a technology challenge. Access to reliable and sufficient electricity is becoming equally critical.
For the UK, the setback raises questions about whether existing power infrastructure can keep pace with the country’s ambitions to become a major AI hub.
