GoKawiilMicrosoft exits Nscale's planned UK AI supercomputer in Essex
Microsoft has pulled out as anchor customer for Nscale's proposed 50MW (expandable to 90MW) AI data center in Loughton, Essex, which was meant to house 23,040 Nvidia GB300 GPUs for Azure starting in 2027. The withdrawal reportedly follows warnings from UK Power Networks that sufficient grid capacity may not arrive until the early-to-mid 2030s. Nscale says the project continues and it is seeking alternative power sources and sites.
GoKawiil's interpretation of the reporting above, not reported fact.
The episode highlights how UK electricity grid constraints, tied to national transmission infrastructure the local network operator doesn't control, could delay or derail large AI infrastructure investments even when customers and hardware are secured. Nscale's insistence that its Microsoft relationship remains strong suggests the companies may still collaborate elsewhere, but the loss of a named anchor tenant could complicate Nscale's efforts to attract financing or other customers for the Essex site.
