Wireless End-Use Power Metering
PNNL investigators have developed a wireless system for electricity end-use metering. This system enables near real-time measurement, tracking, and reporting for hundreds of appliances and heavy electric equipment within a facility. Easy to install and use, the system provides cost-effective solutions for facility managers interested in proactive energy consumption management and researchers studying electricity use.
Individual power meters with 120-VAC or 240-VAC receptacles are connected directly to appliances and report data every 10 seconds to several hours, depending on individual settings. Data are stored centrally and are available for viewing, printing, archiving, and downloading into spreadsheets.
A 3-phase end-use meter is under development and planned for completion in Fall 2005.
Wireless radio technology for the original meters was provided by Inovonics Wireless Corporation. Southern California Edison and Hines GS Properties have contributed through all phases of the project from system conceptualization to deployment. Field tests of the power meters were started in Spring 2005 in a commercial building owned and operated by Hines, and with Southern California Edison and its customers as part of a meter loaning program.
Today, the right energy information is available to make intelligent energy decisions. Isn’t that something you’d like to have before you open your next power bill?
The Wireless Power Meter technology developed by researchers at Pacific Northwest National Laboratory enables near real-time measurement along with tracking and reporting for hundreds of appliances and heavy electric equipment within a facility. Design features include easy installation and cost-effective solutions for facility managers interested in proactive energy consumption management.
Individual power meters with 120-VAC receptacles are connected directly to the appliances and report data at intervals of 10 seconds to several hours, depending on individual settings. Using Inovonics® wireless radio technology, data are then transmitted to a central desk or laptop PC and stand ready for analysis via full-color graphical user interface.
To achieve highly energy-efficient facility operations, the Wireless Power Meter answers the “who-what-where-when-why” of consumption anomalies in power utilization and offers a unique and cost-effective solution to utilities promoting high energy efficiency and demand response programs.
This Wireless Power Meter technology enables management to explore energy efficiency improvements in their facility to optimize operations. It also enables users to orchestrate load management strategies that tune down, refine, reschedule and rethink present strategies, offering cost savings. Either way, for the facility manager who is responsible for the bottom line on energy consumption, this wireless power meter technology offers the right energy information to make intelligent energy decisions.
 When placed between the load and electric outlet, the wireless power meter transmits consumption data to a personal computer standing ready to display the data in increments of ten seconds to several hours. Data can be aggregated to days. |
 Graphic User Interface displays data received from individual electrical meters. |
