Microsoft Withdraws from Major Essex AI Data Centre Project Amid Power Supply Issues

The development of a massive AI data centre, previously championed by the UK government, has encountered a significant hurdle as Microsoft withdraws from the project due to electricity supply concerns.

The facility, spearheaded by British firm Nscale, was announced in 2025 and projected to become the nation’s largest AI data centre. The site in Loughton, Essex, was scheduled to become operational next year.

The project had already faced scrutiny following reports in March that the intended location was still functioning as an active scaffolding yard.

Compounding these issues, Microsoft—intended to be the project’s primary anchor tenant—has officially notified the company that it is terminating its agreement. This decision follows revelations last month that power supply constraints would cause significant delays to the facility’s launch.

The Loughton site was a centerpiece of Keir Starmer’s administration’s 2025 AI strategy, which characterized the development as the “largest UK sovereign AI data centre.” Such facilities serve as the essential infrastructure for AI technologies, including large language models and chatbots.

With Microsoft’s departure, Nscale has lost its only publicly named client for the Essex site. However, reports suggest Microsoft maintains its partnership with Nscale for a separate project located in Norway.

Nscale, which receives backing from major technology players including Nvidia, has sought to establish itself as a premier provider of sovereign data infrastructure in Britain. The loss of a major anchor tenant may complicate the company’s plans for a Wall Street IPO later this year, where it was targeting a valuation of $35bn (£26bn).

An Nscale spokesperson commented: “We remain committed to both the Loughton project and the UK, and we are exploring alternative power sources for the site, in addition to other expansion sites in the UK.

“Our relationship with Microsoft remains strong and long-term, and this unfortunate London-wide grid issue has no impact on our other contracts.”
