- OpenAI halts its main UK data‑centre project due to high energy costs and an unfavourable regulatory environment.
- Stargate UK was announced last September in partnership with Nvidia and Nscale during a US presidential visit. The project aimed to bolster sovereign compute capacity and make Britain a global AI hub.
- UK government says it continues to work with OpenAI but high power prices threaten similar investments.
OpenAI has paused its multi‑billion‑pound “Stargate UK” data centre project, citing spiralling energy costs and regulatory uncertainty.
The artificial‑intelligence company, which burst onto the global stage with ChatGPT, said it will move forward only when conditions allow sustained, long‑term investment. Launched last September alongside partners Nvidia and Nscale during US President Donald Trump’s visit to Britain, the project was hailed as a key pillar of the UK’s drive to become an AI superpower.
Stargate UK was designed to enhance Britain’s ‘sovereign compute’ capacity – essentially the ability to develop and host AI infrastructure on domestic soil. It was meant to power advanced research and commercial applications, complementing existing cloud facilities run by Microsoft and others. But building and operating large‑scale data centres is energy‑intensive.
British industrial electricity prices remain well above those in the US and Asia because gas still dominates the UK generation mix. With oil and gas prices volatile due to the Iran war, wholesale power prices have surged, making long‑term planning difficult. At the same time, UK rules governing data privacy, AI safety and planning approvals remain unsettled. That combination prompted OpenAI to hit pause.
In response, a UK government spokesperson said London is continuing to work with OpenAI and other AI leaders to strengthen compute capacity. Prime Minister Keir Starmer has staked part of his economic strategy on making Britain a global AI hub, pledging pro‑innovation regulation and investment zones for data centres. Yet energy costs threaten to derail that vision.
Critics warn that without cheaper, reliable power, Britain risks losing out to countries like the US, where abundant renewables and regulated tariffs keep industrial electricity costs lower. The episode underscores how the energy crisis is affecting broader tech investment: a world‑leading AI enterprise is unwilling to commit billions while fuel prices remain unpredictable.
For UK energy policy, the pause should be a wake‑up call. Data centres are among the fastest‑growing sources of electricity demand. To attract them, the country must accelerate grid decarbonisation, build more renewable generation and storage, and provide long‑term clarity on energy pricing. Otherwise, flagship tech investments will migrate elsewhere, undermining efforts to diversify the economy beyond financial services.
The intersection of energy and digital policy is increasingly evident, and governments must manage both simultaneously.
