Stellium

Stellium Datacenters is a UK-based data center operator headquartered in Newcastle upon Tyne, England. Its flagship site is a purpose-built data centre campus at the Cobalt Business Park which aims to be one of the most power-efficient and interconnected digital infrastructure hubs in the UK.The campus benefits from direct fiber-optic links including landing points for subsea cables (North Atlantic loop) and a large fibre-ring in the region, positioning Stellium as a strategic location for cloud, interconnectivity and high-performance workloads. With current power capacity around ~30 MW and plans to scale up to 80-120 MW, Stellium offers compelling scale for wholesale / hyperscale clients. 

⚙️ Facility Highlights

• Approximately 30 MW already available on campus, with expansion capability up to 120 MW. 
• Campus design built for Tier III+ (or equivalent) operations, with resilience and high availability embedded. 
• “Cloud-Ready” environment: direct on-ramps to major public clouds (AWS, Azure, Google Cloud, IBM, Oracle) with 1G/10G/100G connectivity. 
• Carrier-neutral, dense network ecosystem with a dedicated fibre ring in Newcastle and access to submarine connectivity. 
• Strong sustainability orientation: collaboration with the Open Compute Project (OCP) on immersion-cooling technology to boost efficiency and reduce carbon impact. 

🔐 Security & Compliance

• Operates secure, enterprise-grade infrastructure with full redundancy and modern facility controls. (General emphasis from company sources)
• The collaboration with OCP signals readiness for advanced cooling, hardware optimisation and efficiency—factors relevant to compliance and sustainability standards. 
• Though specific certifications (e.g., ISO 27001, SOC 2) are not enumerated in publicly available materials, the facility positioning for high-performance / hyperscale deployment implies a high operational standard.

🌐 Connectivity & Carrier Access

• Stellium offers robust connectivity options including integration with major public cloud platforms via high-speed links. 
• The Newcastle fibre-optic ring and campus network underpin strong interconnection and low latency for both national and international traffic.
• Data centre campus serves as a landing point for subsea cables connecting the UK to the Nordics / US / Europe, establishing a strategic network hub role.

💼 Who It Serves

• Hyperscale cloud providers, AI/ML and high-performance computing clients who need large-scale power and connectivity.
• Enterprises in sectors like media & streaming, fintech, healthcare and energy that demand dense compute, high availability and direct cloud integration. 
• Network, content and telecom operators requiring interconnection hubs and submarine-cable access for regional/international traffic.
• Government, academia, start-ups and regional enterprises seeking a platform that combines scale, connectivity and regional UK presence.
