OpenAI pauses UK data centre deal over energy costs and regulation

OpenAI Halts UK Data Centre Initiative Amid Energy Cost and Regulatory Hurdles

OpenAI has temporarily suspended a major UK data centre project, citing rising energy expenses and regulatory challenges as key factors. The initiative, known as Stargate UK, involved constructing a significant data centre in Northumberland and collaborating with tech companies Nvidia and Nscale to produce thousands of advanced AI chips. This followed a broader £31bn UK tech investment package, which the government praised as a step toward establishing the nation as an “AI superpower.”

In a statement, OpenAI emphasized its confidence in the UK’s AI potential, highlighting London’s status as a central research hub and backing the government’s aim to position the country as a global AI leader. “AI compute is foundational to that goal—we continue to explore Stargate UK and will move forward once regulatory frameworks and energy pricing meet the necessary criteria for sustained infrastructure growth,” the spokesperson added.

“We see huge potential for the UK’s AI future. London is home to our largest international research hub, and we support the Government’s ambition to be an AI leader,” an OpenAI representative said.

The UK government has positioned itself as a key player in fostering domestic tech innovation and AI advancement as a catalyst for economic expansion. However, OpenAI’s pause may challenge these aspirations, especially as the company had previously outlined plans to enhance the UK’s “sovereign compute capabilities” and support the national AI Opportunities Action Plan.

The UK-based Stargate project, located at Cobalt in Northumberland, is considerably scaled down compared to its US counterpart, which aimed to allocate $500bn over four years for AI infrastructure development. The decision comes as a potential setback for the government, which has promoted homegrown tech and AI as drivers of growth. Technology Secretary Liz Kendall noted in January that the UK’s AI sector had grown 23 times faster than the economy overall.

While the cited reasons—energy costs and regulatory concerns—are not entirely novel, the timing of the pause has raised questions about the broader implications for UK tech development. Prior to the recent surge in energy prices linked to the Iran conflict, the UK had already maintained higher electricity costs compared to the United States. Meanwhile, the regulatory landscape for AI in the UK has remained largely consistent, with no significant shifts in policy affecting the sector.

OpenAI’s decision also underscores the strategic considerations of major tech companies in large-scale investments. Earlier this week, the firm unveiled preliminary policy proposals, one of which suggested implementing a four-day workweek with full pay to harness an “efficiency dividend” in the evolving AI landscape. The BBC understands concerns about the UK’s regulatory environment include potential legislative changes that could permit AI firms to utilize copyrighted material for training models, which was previously set to be an opt-out option for creators.

This opt-out provision had sparked discontent among artists, including notable figures like Sir Elton John, who felt it would compromise their intellectual property rights. OpenAI reiterated its commitment to investing in talent and expanding its UK footprint, alongside fulfilling obligations to deploy AI systems in public services as agreed with the government.
