Abstract

This report summarizes the Lawrence Berkeley National Laboratory’s research to date in characterizing energy efficiency and automated demand response opportunities for industrial refrigerated warehouses in California. The report describes refrigerated warehouses characteristics, energy use and demand, and control systems. It also discusses energy efficiency and automated demand response opportunities and provides analysis results from three demand response studies. In addition, several energy efficiency, load management, and demand response case studies are provided for refrigerated warehouses.This study shows that refrigerated warehouses can be excellent candidates for open automated demand response and that facilities which have implemented energy efficiency measures and have centralized control systems are well suited to shift or shed electrical loads in response to financial incentives, utility bill savings, and/or opportunities to enhance reliability of service. Control technologies installed for energy efficiency and load management purposes can often be adapted for automated demand response (Open ADR) at little additional cost. These improved controls may prepare facilities to be more receptive to Open ADR due to both increased confidence in the opportunities for controlling energy cost/use and access to the real‐time data.
