Teesside to Become Europe's Largest Data Centre on Former Steelworks Site
The Transformation from Steel to Silicon
The UK government has reportedly selected Teesside - described as the largest brownfield development in Europe - as the location for its second AI Growth Zone, with ambitious plans to build what could become Europe's largest data centre facility.

The strategic importance of this development cannot be overstated. Teesside's transformation represents a fundamental shift in UK industrial strategy, repurposing post-industrial brownfield land for cutting-edge AI infrastructure.
Site Specifications and Scale
The Teesworks site encompasses an extraordinary footprint that dwarfs other European developments:
[cite author="Data Centre Dynamics" source="July 23, 2025"]4,500 acres of brownfield land are being rejuvenated into an industrial zone and freeport known as Teesworks[/cite]
To put this in perspective, 4,500 acres equals approximately 18.2 square kilometers - larger than many European cities. The planned data centre alone will span nearly 500,000 square metres (5.4 million square feet), making it potentially the largest single data centre facility in Europe.
[cite author="Capacity Media" source="September 2025"]Teesworks Ltd, the public-private partnership overseeing the site's redevelopment, has submitted planning permission for a vast data centre spanning nearly 500,000 square metres, which could become Europe's largest[/cite]
Government Strategy and Industry Engagement
The Department for Science, Innovation and Technology (DSIT) has been deeply involved in orchestrating this development, engaging with major global technology companies:
[cite author="Data Centre Dynamics" source="July 23, 2025"]The Department for Science, Innovation and Technology was closely involved in negotiations with an unnamed major investor and has been in discussions with leading tech companies[/cite]
The scope of government engagement reveals the strategic priority placed on this development:
[cite author="Data Centre Dynamics insider source" source="July 23, 2025"]Teesside will be the UK's main AI Growth Zone. Officials have spoken to loads of big companies, including Anthropic, DeepMind, Microsoft, and Google[/cite]
This level of engagement with leading AI companies suggests Teesside could become a hub for frontier AI development, potentially hosting compute infrastructure for training next-generation AI models.
Historical Significance and Economic Transformation
Science Secretary Peter Kyle articulated the symbolic importance of Teesside's transformation in a letter to stakeholders:
[cite author="Peter Kyle, Secretary of State for Science" source="September 2025"]For generations, Teesside was at the heart of British industry, powering the UK's steel production and heavy manufacturing. Now, as it moves from steel to silicon, it has the opportunity to be at the heart of the industries of the future - hosting world class AI infrastructure, unlocking transformative investment for the region, and becoming home to the most powerful data centre in Europe[/cite]
Competing Interests and Infrastructure Challenges
The development faces complex infrastructure challenges, particularly around energy allocation:
[cite author="North East Bylines" source="September 2025"]The government was delaying a decision regarding the building of a hydrogen plant on Teesside. This decision has been delayed in the middle of a row over land which has subsequently been earmarked for an AI data centre[/cite]
The conflict highlights critical resource allocation decisions:
[cite author="Data Centre Dynamics" source="July 23, 2025"]Teesworks and the local public body overseeing its activities, the South Tees Development Corporation, have formally objected to the hydrogen proposal, arguing that it would make their planned data centre unviable[/cite]
Regional Regeneration Impact
The AI Growth Zone designation promises significant economic benefits for the North East region, historically one of the UK's most economically challenged areas. The transformation of Europe's largest brownfield site into a cutting-edge AI facility represents one of the most ambitious regeneration projects in UK history.
Timeline and Next Steps
While the formal announcement appears imminent as of September 2025, construction timelines suggest rapid development:

The project aligns with the UK government's broader AI Growth Zone strategy, which aims to have construction beginning by the end of 2025.
