Microsoft Exits Essex AI Datacentre Deal Over Power Supply Issues
Microsoft has withdrawn from a major UK AI datacentre project in Essex, citing power supply concerns, dealing a blow to the Nscale development.
Microsoft has pulled out of a large artificial intelligence datacentre project in Essex, England, over concerns about adequate power supply, dealing a significant setback to a development that the UK government had championed as a landmark infrastructure initiative.
The project, led by British technology firm Nscale, was announced in 2025 and promoted by ministers as the largest AI datacentre of its kind in the country. The facility was planned to open at Loughton, Essex, next year, with Microsoft serving as its anchor tenant — a role the tech giant has now vacated.

Microsoft's departure underscores a growing challenge facing large-scale AI infrastructure projects globally: securing sufficient and reliable electrical power. Datacentres supporting advanced AI workloads require enormous amounts of electricity, and grid capacity constraints have emerged as a critical bottleneck for developers in the United Kingdom and elsewhere.
The loss of Microsoft as a cornerstone customer raises questions about the commercial viability and timeline of the Nscale project. Anchor tenants typically provide the long-term revenue commitments that underpin financing and construction schedules for capital-intensive developments of this scale. Without a replacement of comparable standing, the project's future trajectory remains uncertain.
The setback comes as the UK government has sought to position the country as a leading destination for AI investment, with large datacentre projects forming a central pillar of that strategy. Continue reading at Business | The Guardian.
