Nebius has agreed to deploy high-density AI infrastructure at Vantage Data Centers’ Newport campus, becoming the first announced commercial capacity commitment in the South Wales AI Growth Zone.
Under the agreement, AI cloud provider Nebius will lease capacity at Vantage’s CWL1 campus to support AI training and inference, as well as agentic and enterprise AI workloads.
The capacity will be powered by NVIDIA technology and is expected to serve businesses, researchers, start-ups and public sector organisations looking for access to domestic AI computing infrastructure.
The deal comes as both the UK Government and private sector seek to rapidly increase the amount of computing capacity available in the country to support growing demand for AI.
Nebius announced in June that it had committed around £1.7 billion to capacity across four UK sites, with its infrastructure deployment using NVIDIA’s DSX AI factory reference design.
For Vantage, the agreement represents another customer for its growing South Wales portfolio. The company says it expects to ultimately deliver more than 1 GW of AI-ready data centre capacity across Newport, Bridgend and Bro Tathan as part of its investment in the region.
Building out the South Wales AI Growth Zone
The CWL1 campus has been operational since 2010 and is already one of the larger data centre campuses in Europe. Its existing power and connectivity infrastructure means it can accommodate the high-density computing hardware increasingly required for AI workloads.
Vantage says electricity consumption at the site is matched with certified renewable energy, while newer facilities use closed-loop cooling systems designed to limit operational water consumption.
The latest deployment is particularly significant because South Wales has been designated by the UK Government as an AI Growth Zone, with the initiative intended to accelerate the construction of the infrastructure needed to support the Government’s wider AI ambitions.
The region already has significant digital infrastructure and electricity grid capacity, as well as fibre connectivity to London. It is also home to a large cluster of semiconductor businesses, giving the Government hopes that the area can attract further investment in AI and advanced technology.
David Howson, President, EMEA at Vantage Data Centers, commented, “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, added, “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.”
The Government will be hoping developments such as this begin to put physical infrastructure behind its AI Opportunities Action Plan, which has placed increasing domestic compute capacity at the heart of its ambitions for the sector.
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.”
While the agreement represents an early commercial commitment within the South Wales AI Growth Zone, significantly more infrastructure will be needed if the UK is to deliver the scale of domestic compute envisaged by the Government. With Vantage alone planning more than 1 GW across the region, South Wales is likely to become an increasingly important test of whether the UK can turn its AI infrastructure ambitions into operational capacity.
