When Ralphs/Food 4 Less wanted to cut power use they looked to one of the food service industry's biggest power draws: refrigeration. With support and incentives from Southern California Edison, Ralphs/Food 4 Less was able to save 17,200,000 kWh at 90 stores in Southern California Edison's Service Area. This amount of energy saved is equivalent to powering over 1500 homes for one year and avoided 10,000 metric tons of CO2 emissions. The upgrades included a number of advanced control systems for all aspects of refrigeration, building and environmental controls, lighting and energy efficient technologies in refrigerated cases.
