Nvidia-backed Nscale faces years of delay as UK power grid struggles to support AI data center

Nscale, a UK-based startup backed by Nvidia, is facing significant delays for its ambitious 'neocloud' data center project in Loughton, Essex. Originally intended to launch in 2027 as a flagship AI supercomputer, the facility is now stalled due to severe power supply constraints. UK Power Networks has indicated that the necessary 90MW of electricity—equivalent to the consumption of 315,000 homes—will not be available until the early 2030s. This project highlights a broader crisis within the UK's energy infrastructure, where a backlog of over 300 data centers is currently awaiting grid connections, with total demand exceeding the nation's capacity by more than 60%. As the UK struggles to balance its renewable energy transition with the massive power requirements of the AI boom, Nscale’s path toward its planned public listing remains complicated by these fundamental infrastructure roadblocks.
