Supermarket Walk-In Freezer Energy Solutions

Profit margins in the grocery space are razor thin, and researchers at 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.

Thermal Energy Storage systems inside walk-in freezers (and distribution centers) improve temperature stability and reduce energy spend and the carbon footprints of grocery stores. 

Learn how Thermal Energy Storage reduced load by 70% and improved temperature stability by 38% inside the freezer of an international grocery chain.
