Britain's energy regulator has proposed forcing datacentre developers to lodge significant upfront financial security—through letters of credit, bonds, or cash deposits—when receiving grid connection offers. The funds would be returned once the facility operates. This measure targets a mounting infrastructure crisis: 315 datacentres await connections with combined power demands that dwarf the nation's peak electricity usage, and Ofgem believes many are speculative ventures unlikely to proceed.

The proposal reflects growing tension between Britain's artificial intelligence ambitions and grid limitations. Ofgem would require projects to meet "hard milestones" including securing customers and financial backing, ensuring scarce grid capacity flows to infrastructure likely to be built rather than options preserved by speculators. The challenge extends globally, with industry research suggesting half of 250+ major datacentre projects announced since 2021 will face significant delays or cancellation, even as demand for computing capacity continues accelerating.
