Launch of UK’s ‘largest AI supercomputer’ delayed by power supply problems
A major AI datacentre in Loughton, Essex, promoted by the UK government as the country's largest AI supercomputer, will miss its planned 2026 launch date. Power supply constraints could push the facility's opening into the mid-2030s.
Why this matters: Governments keep announcing AI infrastructure as if the hard part is the decision. The hard part is actually building it. Power supply is not a footnote — it is the binding constraint on almost every large AI project right now. The UK made this facility a centerpiece of its AI ambitions. A delay of nearly a decade is not a setback. It is a different story entirely. Anyone counting on that capacity for public services or national competitiveness should start adjusting expectations now.
