Plug Load Management System Field Study: Wireless Meter and Controls

This presentation offers background on GSA's Green Proving Ground (GPG) and DOE's High Impact Technology (HIT) Catalyst work, and a field study that assessed a plug load management (PLM) system in two commercial building applications. The Ibis InteliNetwork (TM) PLM system enables users to measure and analyze device energy use and identify opportunities for reduction of plug load energy use, and set times for individual devices (or groups of devices) to turn off when not in use. The presentation gives an overview of the PLM demonstration project, its results, and lessons learned.

Plug Load Management System Field Study

In 2018, NREL performed a demonstration of the IBIS InteliNetwork(TM) plug load management system, which includes: intelligent socket devices, which plug into existing electrical outlets and collect energy usage information; a gateway, which manages communication between the intelligent sockets and the PLM cloud service; and a PLM network, which is a cloud-based measurement and control network for the entire system. Two retail stores served as the field study sites. The PLM system was found to be effective at reducing plug load energy use, with a projected annual plug load reduction of 11% and 18% at the test locations. Retail staff reported that the hardware was easy to use, but no one used the online data management system, intended to analyze and control the hardware. This PLM solution shows promise as an effective means to monitor, control, and reduce plug load energy use, but the economics of the system need to be improved.
