Nvidia-backed Nscale data center delayed years over UK grid power shortage

Nscale's Loughton, Essex data center, billed as the UK's largest AI supercomputer, will not open as planned in 2027 after UK Power Networks said the grid cannot supply enough power until the early 2030s. The site needs 90MW, and Nscale is preparing a £26 billion listing.

• Site requires 90MW, equal to about 315,000 homes
• Over 300 data centers await National Grid connection, totaling 73GW
• Demand exceeds the UK's 45GW capacity by 62%
• Nscale is preparing a £26bn listing with Nvidia backing
