Microsoft drops AI datacentre project in Essex over power supply concerns (www.theguardian.com)

Microsoft has announced it will withdraw from a significant AI datacentre project in Loughton, Essex, due to concerns over power supply issues, marking a setback for Nscale, the British firm behind the development. The datacentre was touted as the UK's largest sovereign facility for AI and was anticipated to play a crucial role in the UK government’s AI strategy announced in 2025. The withdrawal leaves Nscale without its primary customer and raises questions about its ambitions to become a major player in the AI infrastructure space, particularly as it prepares for a potential $35 billion IPO. Power supply challenges surfaced after UK Power Networks indicated they could not meet the energy demands for the site until the early to mid-2030s. This issue underscores the growing energy constraints affecting datacentre developments, where timely access to reliable power is critical for supporting AI technologies. Nscale is exploring alternative power solutions and is committed to the project despite these hurdles. With deep ties to Nvidia and strategic backing from influential figures, Nscale’s ability to navigate these challenges will be vital for sustaining its role in the accelerating AI landscape in the UK and ensuring its long-term viability amid economic pressures.
