Clean up the savings on every aisle.

Keep your cash registers ringing with DTE Energy saving ideas.

With long hours and a range of cooling needs, grocery and convenience stores eat up a lot of energy. In fact, refrigeration represents more than 60% of all electrical use in most stores, with store heating representing more than 50% of all natural gas use.

Data from U.S. Energy Information Administration

Liberty Foods in Detroit replaced its old lighting and more than 200 motors in its coolers and freezers, and it added a new computer in its compressor room, with help from DTE Energy.

Ensure door seals on refrigeration units close tightly
Having tight seals and properly closing doors prevents warm air from entering the unit, reducing energy required for cooling as well as preventing frost build up. Use this rule of thumb: If you can easily slide a dollar bill into the seal, have the seal adjusted.

Clean cooling coils on the backs of refrigeration units
Over time, dirt accumulation impairs proper heat transfer and lowers the efficiency and capacity of refrigerators. As you clean dirt and dust, watch for ice accumulation on coils and remove that as well.

Keep refrigeration and freezer doors shut
Keep the doors of all your refrigeration and freezer units shut as much as you possibly can. Repeated fluctuations in temperature will damage food quality and cost money.

Use display-case shields on refrigerated display cases
Aluminum display-case shields can reduce refrigeration load from the display case by 8% when applied overnight and by 40% when applied over a 24-hour holiday, relative to the load present without the shield. Products are kept colder when the shields are attached and remain colder for several hours after the shields are removed.

Refrigeration costs
For supermarkets, grocery stores, or convenience stores, refrigeration may use up to 40% of the property’s total energy usage.

ENERGY STAR®-certified

Use ENERGY STAR®-certified products
ENERGY STAR®-certified fixtures typically use one-quarter the energy of traditional lighting and distribute light more efficiently and evenly than standard fixtures. In addition to bulbs and fixtures themselves, add lighting controls and/or sensors to reduce energy use.

Use ENERGY STAR -certified refrigerators and freezers
When it comes time to replace your refrigeration and freezer units, purchase model that are ENERGY STAR®-certified. They can save you energy and money over time. You may even be able to find rebates for your purchase from ENERGY STAR® partners.

Save with ENERGY STAR®-certified commercial refrigerators and freezers
Replacing all existing commercial refrigerators and freezers sold in the U.S. with ENERGY STAR®-certified models would result in energy cost savings of more than $790 million each year. These savings would also prevent 17 billion pounds of greenhouse gas emissions, equivalent to the emissions from more than 1.7 million cars.

Humidity Control

Install anti-sweat heaters to control humidity
The latest anti-sweat heater controls sense humidity in a store’s ambient air and reduce the operation of heaters in low-humidity conditions. They promise significant savings and quick payback, and they are relatively easy to install. Savings can be in the 6% to 20% range, according to the Washington State Energy Solutions Database.

Maintain HVAC Equipment

Tune up equipment
Just as a tune-up for a car can improve gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort.
