This report summarizes the Lawrence Berkeley National Laboratory's research to date incharacterizing energy efficiency and open automated demand response opportunitiesfor industrial refrigerated warehouses in California. The report describes refrigeratedwarehouses characteristics, energy use and demand, and control systems. It alsodiscusses energy efficiency and open automated demand response opportunities andprovides analysis results from three demand response studies. In addition, severalenergy efficiency, load management, and demand response case studies are providedfor refrigerated warehouses.This study shows that refrigerated warehouses can be excellent candidates for openautomated demand response and that facilities which have implemented energyefficiency measures and have centralized control systems are well-suited to shift or shedelectrical loads in response to financial incentives, utility bill savings, and/oropportunities to enhance reliability of service. Control technologies installed for energyefficiency and load management purposes can often be adapted for open automateddemand response (OpenADR) at little additional cost. These improved controls mayprepare facilities to be more receptive to OpenADR due to both increased confidence inthe opportunities for controlling energy cost/use and access to the real-time data.
