Plug Load Metering
• Monitoring at each
receptacle
independently
• Radio or Power Line
communication
• Receptacle address
AND appliance address
needed for accurate
measurements
• Often combined with
control (ASHRAE, IgCC,
Ca Title 24)
• Current tap or in-wall
Why RFID appliance tags?
•

•
•
Provides plug load with a unique address at a low cost for 100% accurate appliance
sub-metering and control
Contains overload trip levels between 0.33A/40W and 15A/1875W
Writeable - kWh accumulation written to tag
Simple, intuitive technology for DIY installation

What do the RFID tags do?
•
Unique Plug Identification
– Identifies where each appliance is plugged in, and
when unplugged from receptacle
– Measure energy, monitor assets, accurately control
new and legacy equipment
•
Energy Usage
– Stores accumulated kWh as redundant data
backup (receptacle also has long-range radio
communication of meter measurements)
•
Protection
– Identifies the current rating of each appliance for
overload protection
– Protection from electrocution - power relay is
normally OFF and requires either manual
operation (key fob) or RFID appliance tag to turn
power on at each individual receptacle
– Equipment protection from lightning strikes,
power surges and brown conditions
– Blackout recovery protection that ensures the
power is stable for 15 seconds before allowing
outlets to power ON. Also eliminates excess
inrush demand by staggering restart.

“The ultimate two for one: Appliance specific energy data with integrated appliance protection!”
- Dallas Swindle, DS Design Group

Example of UC Davis Home SafePlug Appliance Data
Goal of the study was to balance solar generation & battery storage with intelligent monitoring and appliance load shedding
 Appliance data from SafePlug (Watts, Amps, Volts) UC Davis is able to monitor all plug loads in real time.
 Intelligent load shedding is only possible when every appliance is accurately measured and can be controlled, regardless of
location.
 100% Customer engagement: RFID Tagging means that only approved appliances consume energy.
 Control strategy is no longer reliant on appliance location.
 Phantom power is easily monitored and eliminated.
 Protection for all appliances during surges, spikes, sags and bad power.
 Intelligent blackout recovery: balanced start-up after black-out/low power conditions eases inrush demand.
 Prioritization: Appliance grouping and prioritization is only possible with SafePlug.

Benefits of Plug-Load Metering with Plug ID Reader
• Measure appliance energy usage in real time for accurate baselining
– Display exactly what equipment is running and how much
energy is being consumed
• Prioritize electrical loads into Critical (“never turn off”) and Non-Critical
groups
• Implement control scenes to shed loads for minutes or hours
• Schedule when appliances can operate
– Eliminate phantom power consumption
– Perform precise peak energy reductions (blackout, DR, TOU
pricing)
• Track and Monitor assets
– Identify what is plugged in, when it is present, where it is
located and if it is actually using energy.
• Protect expensive equipment, coworkers and/or family members from
hazardous fault conditions.
