plugload

Plug load refers to the electricity consumed by devices that are powered through wall outlets rather than by being integrated into a system or circuit. This category covers a wide range of equipment, including consumer electronics (phones, laptops, monitors), office equipment (printers, copiers, coffee brewers), chargers, small kitchen appliances, AV gear, and other peripherals. The term may be written as plugload or plug-load.

In many buildings, plug loads constitute a sizable portion of total electricity use. The energy impact is driven by devices left in standby or sleep modes, devices that remain powered for long periods, and the growth of connected and portable equipment. Because these loads are dispersed and often individually small, cumulative savings can be substantial when targeted with specific controls and device-appropriate strategies.

Common approaches to manage plug loads include intelligent power strips and controllable outlets, occupancy or task-based control, scheduled power-downs, and policies that encourage users to unplug or power down idle equipment. Selecting energy-efficient adapters and devices, promoting user awareness, and removing unnecessary equipment also contribute to reductions. Metering and data analysis using outlet-level submeters or plug load meters help identify high-usage devices and track savings over time.

Overall, plug load management is a practical component of building energy efficiency programs, contributing to lower energy consumption, reduced peak demand, and improved sustainability performance in offices, schools, healthcare facilities, and other environments.
