Sub‑Metering in Data Centres and Critical Infrastructure

Sub‑metering in data centres and critical infrastructure provides continuous, granular energy insight to support resilience, efficiency, and operational assurance.

The Importance of Sub‑Metering in Data Centres

Why Sub‑Metering Is Critical in Data Centres

High‑load, mission‑critical environments require precise, reliable energy measurement at every level.

Load Transparency

Enables visibility of energy use across racks, PDUs, and critical plant.

Operational Resilience

Supports early identification of abnormal consumption and faults.

Capacity Planning

Provides accurate data for growth forecasting and infrastructure upgrades.

Energy Efficiency

Identifies optimisation opportunities without risking uptime.

Cost Allocation

Supports accurate financial tracking by tenant, zone, or system.

Performance Benchmarking

Enables tracking of Power Usage Effectiveness (PUE) (ISO/IEC 30134‑2).
