Is AI infrastructure driving PUE backwards after years of efficiency gains?

Data Centres: Boom and Backlash- What is a good PUE for a data centre?
- Uptime Institute benchmarks show the industry average PUE is around 1.58; hyperscale facilities achieve 1.1–1.2. A PUE of 1.0 would be theoretically perfect (all power goes to IT equipment, none to cooling or overhead).Source: Uptime Institute
- What does Uptime Institute's Tier certification mean?
- Uptime Institute's Tier I–IV system rates data centre resilience: Tier I is basic, Tier IV means fully fault-tolerant with concurrent maintainability. Higher tiers require redundant systems and are often required by enterprise and government customers.Source: Uptime Institute
- Are AI data centres less energy efficient than traditional ones?
- Uptime Institute analysis indicates AI training clusters run at higher power densities than traditional servers, which can degrade PUE when cooling infrastructure is not purpose-built for AI workloads, reversing efficiency gains achieved over the past decade.Source: Uptime Institute
Background
Uptime Institute is the principal standards and research organisation for the data centre industry, best known for its Tier I–IV certification system for data centre reliability and its annual Global Data Center Survey, which tracks power usage effectiveness (PUE) and water usage effectiveness (WUE) across the industry. Its benchmarking reports are the baseline against which operators measure efficiency and sustainability claims.
In the context of April 2026 data centre infrastructure debates, Uptime analysts have been cited on the intersection of AI workloads and PUE: AI training clusters run at much higher power densities than traditional enterprise servers, which can degrade PUE when existing cooling infrastructure is not upgraded. Uptime's work also documented the supply-chain constraints affecting data centre construction — specifically the shortage of heavy-duty transformers and the GE Vernova gas turbine backlog — as structural limits on how fast new capacity can come online.
Uptime is based in New York and operates a global assessor network. Its Tier certifications are widely required by enterprise and government customers as proof of uptime standards, giving it an accreditation function as well as a research role.
