Microsoft cancels UK AI data center project due to power delays
Microsoft has terminated its anchor-tenant agreement for a planned AI data center in Loughton, Essex, developed by Nscale. The decision, made on October 18, 2026, stems from UK Power Networks informing the project that adequate grid power would not be available until the early to mid-2030s. The facility was intended to open in late 2026 or early 2027 and was designed to supply computing power to…
Key points
- Microsoft ended its anchor-tenant agreement for the Loughton, Essex data center on October 18, 2026.
- UK Power Networks stated grid power would not reach the site until the early to mid-2030s.
- The facility was planned to hold 23,040 Nvidia GB300 GPUs with 50 MW initial capacity.
The project was pitched as the UK’s largest sovereign AI data center, with an initial capacity of 50 MW and room to expand to 90 MW. It was to house 23,040 Nvidia GB300 GPUs dedicated to Azure workloads. Microsoft emphasized that this is a site-specific issue, stating that its broader partnership with Nscale remains strong and that other contracts in Norway, Portugal, and the United States are unaffected.
However, Nscale faces challenges beyond Essex. Its flagship site in Norway is currently operating at only 6.4 MW of its planned 30 MW capacity. Nscale is exploring on-site generation options, such as fuel cells, to power the Loughton facility. This cancellation complicates Nscale’s recent US IPO filing, which targeted a valuation of up to $35 billion based largely on its contracts with Microsoft and Anthropic.
