Vantage Data Centers and Nebius (Nasdaq: NBIS) have announced an agreement to deploy Nvidia-powered AI infrastructure at Vantage's CWL1 campus in Newport, Wales, according to a press release from the companies.

The deployment is described as the first announced commercial capacity commitment in the South Wales AI Growth Zone. Under the agreement, Nebius will lease high-density capacity at CWL1 to support AI training, inference, agentic AI and enterprise AI workloads for enterprises, researchers, startups and public sector organizations.

The Newport deployment is part of Nebius' broader UK expansion. In June, the company announced approximately £1.7 billion of committed capacity buildout across four UK sites. The infrastructure leverages Nvidia's DSX AI factory reference design.

The CWL1 campus has been operational since 2010 and is one of Europe's largest data center campuses. Its electricity consumption is matched with 100% certified renewable energy, and its newest facilities use a closed-loop cooling system designed to minimize operational water consumption.

Vantage's broader investment strategy across South Wales targets more than 1 gigawatt of AI-ready capacity across Newport, Bridgend and Bro Tathan.

South Wales was designated as a UK AI Growth Zone based on its digital infrastructure concentration, fiber connectivity to London, high-capacity electricity grid and industrial base. The region also hosts what is described as the UK's largest cluster of semiconductor businesses.
