Microsoft abandoned plans to be the anchor customer for a planned Essex AI supercomputer after UK grid operators warned the transmission and distribution capacity required for a 50–90 MW site likely won't be available until the early–mid 2030s. The proposed build (23,040 Nvidia GB300 GPUs, initial 50MW footprint) lay idle because power delivery — not compute or cooling — became the gating factor, and the developer (Nscale) is now seeking alternate power sources and sites.
— This shows energy-transmission limits are now a strategic bottleneck for national AI industrial policy and may reallocate where investment, jobs, and emissions occur.

Microsoft withdrawal from the Nscale Essex project after UK Power Networks warned grid capacity for the 50MW (expandable to 90MW) facility wouldn’t be available until the 2030s; project planned to host 23,040 Nvidia GB300 GPUs and first chips were expected early 2027.
