Why the UK AI Growth Zone Exists
Built to Solve the AI Compute Constraint
Artificial intelligence at scale is constrained by three things: power availability, deployment speed, and global connectivity. The UK AI Growth Zone has been established to remove these constraints by directing policy support, planning alignment and infrastructure investment into locations capable of supporting power-intensive AI workloads.
For operators like Stellium Datacenters, the designation provides a framework that accelerates the delivery of production-ready AI infrastructure rather than experimental or future capacity.
The North East of England has been designated as a core AI Growth Zone hub because it can support energy-dense compute, large-scale data centre development, and direct global network connectivity — all at a scale required by modern machine learning platforms.
This is not an innovation zone in theory. It is an infrastructure zone designed to support production AI systems.
Why Cobalt Park – the UK Designated AI Growth Hub?
A Location Chosen for Power, Scale and Connectivity
Cobalt Park, near Newcastle, has been selected because it combines access to high-voltage grid infrastructure, a low-carbon energy mix, and established fibre and subsea connectivity. These characteristics make it suitable for the type of AI-ready data centre campuses operated by Stellium Datacenters.
Its geographic position provides direct routing between the UK, North America, mainland Europe and the Nordics, supporting latency-sensitive AI training, inference and data movement.
For hyperscale and AI-first cloud providers, this means fewer compromises: power can scale, networks perform, and deployments can move quickly.
Stellium’s Role in the UK AI Growth Zone
Stellium Datacenters is a core infrastructure enabler of the UK AI Growth Zone. Located within Cobalt Park, Stellium provides the physical foundations required to deploy and operate AI platforms at national and global scale.
Stellium is an AI-enabled, OCP Ready™ certified data centre provider, engineered specifically for modern machine learning, HPC and hyperscale cloud workloads. The campus brings together exceptional, scalable renewable power, direct global subsea connectivity, and open, standards-based infrastructure designed for high-density compute environments.
This is not speculative capacity. Stellium delivers production-ready AI infrastructure today, in a location explicitly designated to support the UK’s long-term AI strategy. For organisations building and operating large-scale AI systems, Stellium removes the traditional blockers to deployment — power, connectivity and time to scale.

Global Subsea Connectivity
Direct Routes for Global AI Platforms
Stellium hosts subsea cable landing infrastructure connecting the UK directly to North America, mainland Europe and the Nordics. These routes provide ultra-low latency, high-capacity paths for distributed AI training, inference and cloud workloads.
For AI platforms operating across regions, direct subsea access reduces network hops, improves performance predictability and strengthens resilience across global deployments.
UK Fibre and Carrier-Neutral Connectivity
Dense Fibre, Real Choice
Stellium operates a fully carrier-neutral campus with access to a broad ecosystem of national and international network providers. This allows customers to architect networks for performance, redundancy and scale, supporting multi-cloud, hybrid and private AI platforms.

Power and Energy Infrastructure
Power First. Always.
AI and machine learning platforms are fundamentally constrained by power. Stellium is designed with this reality at its core.
The campus is supplied with up to 80 MW of 100% renewable, REGO-certified power, delivered directly from the 275 kV National Grid, with infrastructure in place to scale to 180 MW as demand grows. The North East also benefits from one of the lowest carbon intensity energy profiles in the UK, supporting hyperscaler sustainability and reporting requirements.
Stellium further enhances energy resilience and efficiency through on-site solar generation, battery energy storage, and HVO-based standby systems, reducing reliance on fossil fuels while maintaining mission-critical reliability.
This power architecture is designed to support high-density AI deployments, including Nvidia-based machine learning clusters, without compromising scalability or long-term growth.
Is your data centres “100% Renewable” claim ready for a 2027 audit?
We have moved to Half-Hourly (HH) Matching
Here is the physical reality:
- The 95.4% Benchmark: While the industry average for real-time renewable matching is just 42.64%, Stellium’s average monthly score is 95.4% – more than double the standard.
-
75% Lower Actual Emissions: Because we match our usage to actual generators every 30 minutes, our real-world carbon footprint is 75% lower than a standard REGO-backed UK competitor.
-
Radical Transparency: We provide our clients with monthly reports showing exactly which asset powered their racks for every single half-hour period.
