Supermarket Cold Storage Solutions
Viking Cold Solutions is improving energy efficiency across the global cold chain.
See How


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.

Grocery and supermarket chains are constantly seeking innovative yet proven methods to reduce energy spend and the carbon footprints of their stores. 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.


is among the top two operational expenses for a cold storage facility.

High Costs

Peak demand charges can be up to 70% of your electricity bill.

24 Hours a Day

Temperature control is required around the clock to keep food safe.

Learn how Thermal Energy Storage reduced load by 70% and improved temperature stability by 38% inside an international grocery chain’s walk-in freezer.


Viking Cold’s Thermal Energy Storage System makes it possible for supermarkets to protect what is vital while intelligently storing and deploying refrigeration to reduce energy costs. Our Thermal Energy Storage System is a passive system that never needs maintenance and works in parallel with existing refrigeration systems. As a result, electricity peak demand is reduced by up to 90 percent, a significant cost savings. 

The system can be easily installed without any upgrades to your current refrigeration equipment, adding redundancy and maximizing savings.

Cast Your Vote: Viking Cold & Eversource Project Selected as Finalist for 2019 ESNA Innovation Award

Viking Cold Solutions is pleased to have been named a finalist for the 2019 Energy Storage North America Innovation Awards! The ESNA Innovation Awards recognize excellence and impact in energy storage project development. Viking Cold has been recognized for its deployment of eight Thermal Energy Storage (TES) systems as part of a utility-backed demand management program in Massachusetts. These behind-the-meter TES systems store and facilitate the management of approximately 1.3 MW of energy onsite. This project is noteworthy because Viking Cold’s solution leverages the facilities’ existing refrigeration systems to store cold energy and discharge it over long periods of time (up to 13 hours) when it is most beneficial for the grid and the facility operator, thus lowering energy costs, increasing resiliency, and helping the environment. The Greater Boston Food Bank, the program’s first installation, has already seen a 75% reduction in energy consumption and a 76% reduction in demand during its four-hour peak demand period. “As the largest hunger relief organization in New England, our goal is to provide healthy meals to those in need across Eastern Massachusetts,” said The Greater Boston Food Bank SVP of Supply Chain and Food Acquisition, Cheryl Schondek. “We strive for cost-saving operational efficiencies, and our partnership with Eversource and the installation of the Viking Cold TES system better enables us to achieve this goal. We appreciate their commitment to our mission to end hunger here.” You can read more about the TES project online here. Please help Viking Cold win this year’s ESNA Innovation Award – you can vote with the form online here. Deadline is September 12, 2019.
