What is Branch Circuit Monitoring and How Does It Impact Power Usage Effectiveness?

November 7, 2017 Mark Gaydos


Many people ask, “What is Branch Circuit Monitoring?”

The answer: Branch Circuit Monitoring enables users to track power usage effectiveness (PUE) from a central location. This includes all the way down to the level of the individual branch circuit, and all the way up to the utility meter. It covers both IT and facilities equipment.

Branch Circuit Monitoring is important for several reasons.

Capacity Planning

Branch Circuit Monitoring allows the data center manager to track total load vs. available capacity in real time, for each individual cabinet. This information helps with capacity planning and allows for greater operational efficiency and energy savings and can be shared with the BMS.

Load Balancing

Monitoring real-time loads across the A & B sides of panels guards against cascading failure.

Risk Reduction

Alarms at the Branch Circuit level alert users if a pre-established threshold or breaker limit is near. This allows managers to make changes to avoid overload and downtime.

Accurate Billing

This level of granularity enables Colocation providers or enterprise data centers to track in real-time the power usage by individual tenants and departments for accurate billing and charge-back.


Visibility into the energy demands of the entire facility, down to individual systems and beyond, enables users to reduce risk, plan ahead for capacity needs, bill accurately, detect inefficiencies and make changes to help optimize energy usage.
