Microsoft exits Nscale's Loughton AI data centre as UK grid power slips into the 2030s
A hyperscaler walking away from a named anchor-tenant deal shows that grid connection dates, not capital, now decide where AI capacity is built. Developers and investors should treat confirmed energisation dates as a core diligence item and price projects that lack them accordingly. Enterprises planning UK-hosted AI workloads should check that their providers' capacity roadmaps are backed by secured power.
What Happened
Microsoft has ended its contract for Nscale's planned AI data centre in Loughton, Essex, following delays to the site's grid connection. Reports say UK Power Networks told Nscale that sufficient power would not be available until the early to mid-2030s. Microsoft had been expected to be the main customer for the 50 MW facility, which could scale to 90 MW, and Nscale says it will proceed with the development.
