OpenAI pauses UK data centre

OpenAI picked Britain for a flagship artificial intelligence data-centre push in September 2025, then hit pause on April 9, 2026. The company said the numbers no longer worked because British industrial power is expensive and the country’s rules on using copyrighted material to train artificial intelligence are still unsettled. (cnbc.com, bloomberg.com) This was not a vague idea on a slide deck. OpenAI had announced Stargate UK with Nvidia and Nscale, and the first phase was meant to put about 8,000 Nvidia processors at Cobalt Park in North Tyneside, with room to scale much higher later. (gov.uk, tech.eu) A data centre for artificial intelligence is basically a warehouse full of chips that turn electricity into answers. If the electricity bill is too high, the whole business starts to look like running a steel mill in the wrong country. (openai.com, gov.uk) Britain has been wrestling with that problem for years. The Department for Energy Security and Net Zero updated its industrial energy price series on April 7, 2026, and industry groups have spent months warning that British factories still pay more for power than rivals in France or Germany. (gov.uk, uksteel.org) OpenAI’s complaint was even sharper than that Europe-versus-Europe comparison. Reporting on the pause said British industrial electricity can run about four times the United States level, which is a brutal difference when one site can burn through power around the clock. (thenextweb.com, bloomberg.com) The second problem was copyright. Training a large language model means feeding it huge volumes of text, images, and other material, and Britain has spent the past 16 months arguing over when that requires a licence, when creators can refuse, and how developers must disclose what they used. (gov.uk, assets.publishing.service.gov.uk) That fight is not theoretical. The British government opened its copyright and artificial intelligence consultation on December 17, 2024, closed it on February 25, 2025, and only updated the page on March 19, 2026, after publishing a report and impact assessment. (gov.uk, assets.publishing.service.gov.uk) So OpenAI was being asked to place a long-life infrastructure bet in a country where two core inputs were still moving under its feet: the price of power and the rules for training data. That is like signing a 15-year lease before you know your rent or whether your raw materials are legal to use. (cnbc.com, gov.uk) The awkward part for Britain is that the government had presented OpenAI as proof that the country could become an artificial intelligence hub. In July 2025, London signed a strategic partnership with OpenAI, and in November 2025 OpenAI announced UK data residency and a Ministry of Justice deal covering 2,500 civil servants. (gov.uk, openai.com) The pause does not mean OpenAI is leaving Britain. The company said it still sees “huge potential” in the country and will keep working with the government on ChatGPT and other public-service uses, but the expensive part — the concrete, cables, transformers, and chip racks — is waiting for better conditions. (bloomberg.com, cnbc.com) That leaves a simple scoreboard for countries chasing artificial intelligence investment in 2026. Nice speeches can win an office opening, but cheap reliable electricity and stable copyright rules decide where the giant machine actually gets built. (openai.com, gov.uk, gov.uk)
