Launch of UK’s ‘largest AI supercomputer’ delayed by power supply problems

Datacentre hailed by government was supposed to start operating next year but may be held back into mid-2030s

A huge datacentre project hailed by the UK government will miss its launch date next year and could be delayed into the mid-2030s.

The site in Loughton, Essex, was described as the country’s largest AI supercomputer when it was announced in 2025, but power supply problems mean it now faces a lengthy wait before coming online.
