A major tech company has decided to withdraw from a significant artificial intelligence data center initiative while the developer seeks alternative energy options.
Microsoft has halted its plan to invest in a supercomputer at Nscale’s AI data center in Loughton, England, which was expected to be the largest in the U.K. The BBC reported this on Sunday, highlighting how power shortages are starting to impede data center expansion efforts. In fact, U.S. projects hoping to connect to PJM are now facing an average wait of over eight years to begin operations, as noted by the Rocky Mountain Institute.
A Microsoft spokesperson stated, “We remain committed to our partnership with Nscale, including work to build robust digital infrastructure and support AI growth globally. This decision relates to a single site.”
According to the Telegraph, Nscale learned that the Loughton site would not have access to grid power until the 2030s. The company, which is supported by Nvidia, claims to be “the only full stack sovereign AI infrastructure provider in the UK,” as mentioned by Nscale CEO Josh Payne on the company’s website.
Nscale did not respond immediately to requests for comment from the Daily Caller News Foundation.
The supercomputer was projected to house over 23,000 Nvidia chips, with arrivals scheduled for early 2027, based on a Nscale press release from September 16, 2025.
This project was part of a broader $30 billion investment in AI for the U.K., as Microsoft announced on the same day. Microsoft Vice Chair and President Brad Smith emphasized that the decision to invest heavily is significantly influenced by the government’s efforts to reform planning procedures and increase electricity capacity.
Nscale reassured that they remain devoted to both the Loughton project and the broader ambitions in the U.K., exploring alternative power sources for the site while considering additional potential expansion areas. They also mentioned, “Our relationship with Microsoft remains strong and long-term.”
Furthermore, the company noted that the grid issues in London won’t impact its other partnerships, as it continues its collaborations with Microsoft in the U.S., Norway, and Portugal, as reported by the BBC.
