More than 13,000 object to Chapelcross plan for world's largest AI data centre campus

Nov 14, 2026
CX Tech's proposed 1,000MW campus in Dumfries and Galloway would use seven million MWh a year at full capacity; a Scottish Greens campaign has gathered the objections.

More than 13,000 people have lodged objections to CX Tech's plans for an AI data centre campus at Chapelcross in Dumfries and Galloway, Scotland, through a campaign run by the Scottish Greens, The National reports.

If approved, the campus would be the largest data centre campus in the world, with a capacity of 1,000MW, and would use seven million MWh of energy a year at full capacity, according to the report. CX Tech says it would be built over eight years, create 750 construction jobs, 450 permanent roles and 40 apprenticeships, and be "designed to be operationally net zero".

Campaigners point out that the applications were submitted weeks after the Scottish Government agreed to pause decisions on hyperscale data centre applications until national guidance is produced. They also object that the campus would be built on farmland rather than the existing Chapelcross brownfield site, covering an area the size of 77 football pitches, and say it would put heavy strain on the region's energy grid and natural environment.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
