Partner: California Plug Load Research Center

This research identified and prioritized energy end uses with high-potential impact on plug load consumption, and assessed the effectiveness of different energy efficiency program design approaches on these device categories.


Plug load, the energy used by plugged-in devices, is increasing its share of overall energy use in commercial buildings. The California Plug Load Research Center (CalPlug) at the University of California, Irvine, identified new opportunities for managing and reducing energy consumption associated with commercial customer plug loads. Their research involved reviewing utility programs, historical activity and trends in ComEd’s plug load measures, regional estimates for current commercial stock of device categories matching the territory and population served by ComEd, and trends in commercial devices.


In their final study, CalPlug developed a protocol for comparing utility plug load program features and technologies and identifying potential gaps. They reviewed and categorized plug load devices that use the most energy in ComEd’s service territory and made recommendations on how ComEd could incorporate them into their energy efficiency programs.

The Emerging Technologies Team is reviewing the report and determining next steps, including incorporating CalPlug’s recommendations into ComEd’s current energy efficiency offerings and exploring additional research opportunities.
