Microsoft Walks Away From Essex AI Data Center as UK Power Fails It Again
Microsoft canceled a £2 billion AI data center project in Essex, UK, due to power grid delays. The facility, planned for Nscale, was to house 23,000 Nvidia chips and supply Microsoft's Azure cloud. Grid officials indicated power might not be available until the 2030s. Microsoft's other Nscale contracts in Norway, Portugal, and the US remain unaffected. Nscale is exploring alternative power options for the Essex site.
