Microsoft withdraws from UK AI datacentre project in Essex due to power supply issues
Key points
- Microsoft withdrew from Nscale's Essex AI datacentre project.
- Power supply concerns were cited as the reason for Microsoft's exit.
- The project was intended to be the UK's largest AI datacentre.
- Nscale lost its only publicly announced customer for the Loughton site.
Microsoft Exits UK Datacentre Project
Microsoft has withdrawn from an agreement to be the anchor tenant for a large AI datacentre project in Loughton, Essex. The project, developed by British company Nscale, was announced in 2025 and slated to open next year as the UK's largest AI datacentre.
Power Supply Concerns Cited
The primary reason for Microsoft's withdrawal was concerns regarding the power supply for the facility. This issue emerged a month prior, indicating that the project would face significant delays in coming online due to power constraints.
Impact on Nscale and UK AI Strategy
Nscale, backed by companies including Nvidia, has positioned itself as a 'sovereign' datacentre provider for the UK. The loss of Microsoft, its only publicly announced customer for the Essex site, could undermine Nscale's ambition for a $35 billion Wall Street flotation this year. The UK government had highlighted the Loughton project as central to its AI strategy in 2025.
Broader Context of UK AI Infrastructure
The UK government's AI strategy has focused on Nvidia-backed companies like Nscale and US-based CoreWeave to build AI infrastructure. While investments in AI contribute to the UK's economic performance, the setback for the Loughton project highlights potential vulnerabilities in the 'neocloud' model, which involves companies with deep ties to Nvidia building key AI infrastructure.

How outlets covered it
AI infrastructure companies, including Nvidia, Microsoft, and Cisco, informed UK ministers that public opposition to datacenters could halt construction within a year. They propose a "compact" to demonstrate community benefits from datacenters, such as allowing local councils to retain more tax revenues, to prevent US-style protests.
Microsoft has pulled out of a planned AI datacentre project in Loughton, Essex, developed by Nscale, citing concerns over power supply availability. This withdrawal removes the anchor tenant from what was intended to be the UK's largest AI datacentre, potentially impacting Nscale's planned Wall Street flotation.
