UK's largest AI supercomputer delayed to mid-2030s over power supply issues

The UK government's flagship AI supercomputer project in Loughton, Essex, will miss its planned 2026 launch due to power supply constraints, with completion potentially slipping to the mid-2030s. This highlights grid capacity as a critical bottleneck for AI infrastructure, a pattern seen in other regions. The delay undermines UK AI ambitions and raises questions about national competitiveness.
