Profit margins in the grocery space are razor thin, and researchers at energystar.gov estimate that $1 in energy savings is equivalent to increasing sales by $59. Energy demands in U.S. supermarkets are massive, with refrigeration and lighting accounting for over 50% of total energy use. Each year, the average American supermarket consumes roughly 50 kilowatt-hours (kWh) of electricity, and 50 cubic feet of natural gas per square foot. This translates into average annual energy costs of $200,000, and the emission of 1,900 tons of CO2 into the atmosphere–the equivalent of 360 vehicles. Even small grocery stores have significant energy requirements as walk-in freezers experience severe heat infiltration during operating hours, necessitating the consumption of more power to keep foods at the desired temperature.
Learn how Thermal Energy Storage reduced load by 70% and improved temperature stability by 38% inside the freezer of an international grocery chain.
Grocery Business recently published an interview with Viking Cold's VP of Sales & Marketing, Collin Coker as part of their 2019 Equipment & Design Annual Report. The Annual Report is a comprehensive guide to help retailers create efficient, productive, tech-enabled stores. Coker outlines how Thermal Energy Storage adds efficiency to refrigeration, how our system's thermal mass is different from the thermal mass of the food, and other benefits beyond saving energy.
Progressive Grocer has published an article outlining the not-to-distant future of sustainable grocery store refrigeration. Numerous technologies from companies like Viking Cold, Emerson, Honeywell, and CoolSys are referenced as the key to what is rapidly becoming the new normal in grocery stores: improved refrigeration sustainability.
An article on the Grocery Business website describes the importance of understanding multiple categories of sustainability standards and why each Scope 1, Scope 2, and Scope 3 emissions goals are important for grocers to remain competitive. Learn more about the expectations of customers, competitors, investors, and even CPG brands for grocers to improve their sustainability.
