AI boom forces data centres to adopt new energy and security architecture

28.11.2025

The sharp rise in the power density of modern AI workloads is fundamentally changing the requirements for data centres. New GPU clusters (Graphics Processing Unit) require 80 to 100 kilowatts per rack, driving up power consumption, which currently stands at only around 36 kilowatts, while legal requirements such as PUE limits and the obligation to use 100 per cent green electricity from 2027 onwards are putting additional pressure on operators.

In addition to the technical dimension, physical security is also coming into focus – failures due to lack of power availability, cooling problems or unauthorised access can now not only interrupt operations, but also jeopardise entire business models.

‘Energy supply is no longer a “facility detail”. It is the central lever for availability, compliance and reputation,’ emphasises Achim Dewald, project manager at data centre specialist Prior1.

Best practices show that resilience only arises when highly available energy architecture is combined with clear physical security. This includes redundantly designed feed points, tested emergency power generators, N+1 redundancy for cooling technology, meshed grounding systems and a clean separation of energy and data paths.

Modern data centre concepts also rely on the defence-in-depth principle for physical security. Multi-layered access controls, clearly defined security zones and fire compartments with gas extinguishing technology ensure that the infrastructure remains stable even in the event of partial failure of individual systems.

The combination of a robust power supply, precise monitoring down to the sub-distribution level and seamlessly documented physical security is becoming the new standard scenario. For operators, holistic planning that integrates energy architecture and security concepts while complying with standards such as EN 50600 and Tier certifications is no longer optional, but mandatory – especially in AI-driven high-load environments.
