B O N N E V I L L E P O W E R A D M I N I S T R A T I O N Smart Power Strips in Commercial Office Applications RTF August 30, 2011

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 2 Goal Today  To update UES estimates and move provisionally deemed smart strip measures to active status for commercial office applications Using updated savings from BPA engineering research

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 3 Background  RTF Provisionally deemed smart power strips in a commercial office in March kWh $20/unit 4 year Measure Life  RTF approved Research Plan 50 unit sample 2 week pre/post metering Collect information on equipment plugged in and settings

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 4 Smart Power Strips  Resemble traditional power strips, but have outlets with different functionalities.  Control outlet and controlled outlets Some also have outlets that will always remain on  Load Sensor  Occupancy Sensor

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 5 Smart Power Strips  Load Sensor When a control device is turned off or enters sleep mode, the Smart Power Strip cuts power to the controlled peripherals: items such as printers, heaters, speakers.  Occupancy Sensor The occupancy sensor cuts power to the controlled peripherals: items such as printers, heaters, speakers.

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 16 Measure Checklist

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 17 Measure Requirements  Must be installed in commercial offices occupied a minimum of 50 hour per week  Must be at least 1 device plugged into strip, in addition to desktop/laptop/monitor Okay to use with Network PC management as long as more than desktop/monitor plugged in

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 18 Continued Research  Follow up with metered units periodically to check if still installed  BPA to conduct metering on additional 24 work spaces with same metering process Study using occupancy sensor devices

B O N N E V I L L E P O W E R A D M I N I S T R A T I O N 19 Motion for Approval  Motion to approve UES estimate to active status for smart power strips (load and occupancy sensing) in commercial office applications, with a sunset date of September 2013 (2 years)
