OpenAI halted the development of the Stargate data center in the UK due to electricity costs.

OpenAI has suspended the Stargate data center project in the UK due to high energy costs and regulatory challenges.

OpenAI announced a temporary halt to the work on the Stargate project in the UK, citing high electricity costs and regulatory difficulties. The project was announced in 2025 amid a large wave of investment from American tech companies.

In their statement, OpenAI emphasized that the UK’s potential in AI development is great, but realizing such ambitions requires stable infrastructure, where computing power plays a key role. The company plans to return to this project if economic and regulatory conditions improve.

The plans to create the Stargate data center were presented in September 2025, during Donald Trump’s visit to the UK. Although the country’s government has identified AI and data centers as important economic priorities, high energy prices have become a significant barrier to the project’s implementation. It is worth noting that NVIDIA and local developer Nscale were collaborating with OpenAI on the project.

The current situation with the Stargate project may impact future investment decisions of other tech companies considering opportunities in the UK. Experts emphasize that stable energy prices and clear regulatory policies are key to attracting such investments.
