First AI Infrastructure Deployment Announced for South Wales AI Growth Zone

The South Wales AI Growth Zone has reached a significant milestone with its first announced commercial capacity commitment, as Vantage Data Centers and AI cloud company Nebius agree to deploy high-density, NVIDIA-powered AI infrastructure in Newport.

The deployment will support growing UK demand for domestic AI compute capacity, with Nebius leasing high-density capacity at Vantage’s CWL1 campus.

The infrastructure will support AI training, inference, agentic AI and enterprise AI workloads, serving enterprises, researchers, startups and public sector organisations seeking access to advanced AI infrastructure.

Expanding AI compute capacity in South Wales

The Newport capacity forms part of Nebius’ wider UK expansion and commitment to scaling domestic AI compute capacity.

In June, the company announced approximately £1.7 billion of committed capacity buildout across four UK sites. Its UK infrastructure buildout leverages NVIDIA’s latest full-stack, end-to-end DSX AI factory reference design and supports the UK Government’s AI Opportunities Action Plan.

The agreement also builds on Vantage Data Centers’ long-standing presence in Newport.

David Howson, president, EMEA, Vantage Data Centers, said:

“This is an important milestone for South Wales and for the UK’s AI infrastructure ambitions. Nebius is scaling AI cloud infrastructure in the UK at a time when demand for domestic compute capacity continues to accelerate. Vantage’s Newport campus provides the scale, connectivity and operational excellence needed to support that growth, and we’re proud to help establish South Wales as a leading destination for AI investment.”

Gary Tierney, general manager for EMEA at Nebius, said:

“The UK is one of the places where AI is being built, deployed and adopted by startups, enterprises and the public sector. Vantage’s Newport campus gives us a strong foundation to expand access to NVIDIA-powered AI infrastructure in the UK and support customers building the next generation of AI applications.”

Vantage’s growing investment in Wales

Operational since 2010 and one of Europe’s largest data centre campuses, Vantage’s CWL1 campus provides the scale, connectivity and power infrastructure required for high-density AI workloads. It serves a diverse base of hyperscale, enterprise and public sector customers.

According to Vantage, electricity consumption at CWL1 is matched with 100% certified renewable energy. Its newest facilities are designed to minimise operational water consumption through a closed-loop cooling system that recirculates water rather than evaporating it, supported by air-cooled chillers and the use of free cooling when ambient conditions permit to reduce energy consumption.

CWL1 is part of Vantage’s multi-billion-pound investment strategy across South Wales, where the company expects to deliver more than 1GW of AI-ready capacity across Newport, Bridgend and Bro Tathan.

Adam Price, Welsh Government Cabinet minister for Enterprise, Connectivity and Energy, said:

“This announcement marks an important milestone for the South Wales AI Growth Zone and demonstrates Wales’ growing reputation as a strategic location for the infrastructure that will power the AI economy. Nebius and Vantage’s investment will help unlock new economic opportunities, support highly skilled jobs and reinforce Wales’ position as a leading destination for advanced digital investment. We look forward to working with partners to maximise the benefits of this investment for businesses, communities and the wider Welsh economy.”

UK Government AI Minister Kanishka Narayan said:

“This Government wants to put AI to work as a tool for renewing Britain and delivering new jobs. It is central to our mission to reindustrialise the country, drive good growth in every postcode and ensure our public services match-fit for the decades ahead. Making that happen relies on having cutting-edge compute–the horsepower that makes AI possible–here on home shores. The infrastructure at Newport will create new high skilled jobs in South Wales and help British businesses and innovators using AI to solve some of the toughest problems.”

South Wales AI Growth Zone

South Wales was designated as a UK AI Growth Zone in recognition of its concentration of digital infrastructure, fibre connectivity to London, high-capacity electricity grid infrastructure and strong industrial base.

The region is also home to the UK’s largest cluster of semiconductor businesses, creating a growing ecosystem for advanced technology, AI infrastructure and high-value digital investment.

More information about the UK’s AI Growth Zone programme is available through the UK Government’s AI Growth Zones resources.

Further listening: What do AI Growth Zones mean for Wales?

For readers interested in the wider implications of AI Growth Zones for Wales, a recent episode of Silicon Valleys explores what the developments could mean for the country’s technology ecosystem and wider economy.

Hosts David Sadler and Liam Betsworth are joined by James Smith, founder and CEO of FinTech Wales member Critical Cloud and former co-founder of DevOps Group, to discuss the opportunities presented by the AI Growth Zones in North and South Wales, including infrastructure investment, skills, jobs and AI adoption among Welsh businesses.
