OpenAI Pauses Stargate UK as Energy Costs and Copyright Rules Block the Path
In short: OpenAI has paused its Stargate UK data centre project, citing the high cost of industrial electricity in Britain and an unfavourable regulatory environment around AI copyright. The project, announced in September 2025 alongside Nvidia and Nscale, had planned to deploy 8,000 GPUs at sites in north-east England, scalable to 31,000 over time. OpenAI states it will proceed when "the right conditions" allow, without providing a timeline.
What Stargate UK Was Supposed to Be
Stargate UK was presented in September 2025 as a sovereign AI infrastructure project: a collaboration between OpenAI, Nvidia, and British cloud provider Nscale to establish data centre capacity in north-east England for local AI model execution. The sites included Cobalt Park near Newcastle and Blyth, both within designated AI Growth Zones by the UK government, seen as a cornerstone of its artificial intelligence industrial strategy.
The project gained diplomatic and commercial significance during US President Donald Trump’s state visit to Britain. While OpenAI didn’t disclose investment details, the broader US Stargate project continues with data centre construction under way, backed by a $40 billion bridge loan from SoftBank.
The Energy Cost Problem
OpenAI identifies the most significant obstacle as the cost of electricity in Britain, which is among the highest in IEA member states, more than four times that of the United States, Finland, Norway, and Sweden. For a 100-megawatt data centre, this differential is a structural issue, making it difficult to operate large-scale AI inference workloads at such a site due to higher operating costs.
Additionally, the UK’s grid connection queue has experienced dramatic growth, with an estimated 75 gigawatts attributable to data centre projects. The construction time for buildings (18–24 months) pales in comparison to the years it takes to obtain grid connections (3-8 years), exacerbating infrastructure challenges.
