OpenAI pauses UK data centre project over energy costs and regulation
OpenAI has halted its Stargate UK project, a multi-billion pound data centre planned for North Tyneside, citing concerns about energy costs and the regulatory environment. The company said it would only proceed when "the right conditions" enable long-term infrastructure investment.
The project, announced in September, was designed to house powerful AI chips developed with partners Nvidia and Nscale. It formed part of a wider £31bn UK tech investment package that the government promoted as evidence of Britain's potential as an AI superpower.
An OpenAI spokesperson said the company remains committed to the UK and will continue exploring the project. "We see huge potential for the UK's AI future," the statement read. "London is home to our largest international research hub."
What triggered the pause
OpenAI cited two specific barriers: energy costs and regulation. Neither is new. The UK's electricity prices have long exceeded those in the US, even before recent global energy price increases. The regulatory landscape around AI has also remained relatively stable.
However, the BBC understands that regulatory uncertainty played a key role. The government had previously signalled it would make copyright training an "opt out" decision for creators-effectively allowing AI companies to use copyrighted works without permission. This proposal faced significant backlash from artists, including Sir Elton John.
The government has since appeared to step back from that position, creating uncertainty about the legal framework for AI development in the UK.
The government's response
The pause represents a setback for ministers who have positioned AI for Government as a driver of economic growth. Technology Secretary Liz Kendall said in January that the UK's AI sector has grown 23 times faster than the economy as a whole.
A government spokesperson said the UK had attracted more than £100bn in private investment in AI and data centre infrastructure since the current administration took office. "Our focus is on continuing to create the right conditions for investment in the UK's AI and data centre infrastructure," the spokesperson said.
Context: How tech companies make decisions
OpenAI's move reflects how large technology firms approach major infrastructure commitments. The company has committed $500bn to its US-based Stargate project over four years-a scale that makes the UK project appear modest by comparison.
The timing is also telling. Earlier this week, OpenAI outlined policy proposals including a four-day working week on full pay, framed as an "efficiency dividend" in response to more capable AI systems. The pause on Stargate UK suggests the company is selective about where it commits resources.
OpenAI said it would continue investing in talent and expanding its presence in the UK, including deploying AI systems in public services. But the data centre project-central to the government's infrastructure ambitions-remains on hold.
For government officials overseeing technology policy and economic development, the decision underscores how regulatory clarity and cost competitiveness directly influence where major tech companies build their infrastructure. Generative AI and LLM development depends on substantial compute capacity, making these decisions consequential for national AI capabilities.
