Smart $aver® Incentive Program - Energy Efficient Grocer

The average grocery store can save $15,000* a year by switching to LED lighting.

  • Cash incentives from Duke Energy for installation
  • No infrared radiation equals longer shelf life for fresh foods
  • Life span: 5-plus years
  • Lower maintenance costs
  • Dimmable and controllable

* Based on average store size and electric rates.

Benefits of LEDs

Changing refrigerated display case lighting to LED light strips saves energy and has been shown to appeal to customers significantly more than linear fluorescent lamps.
T8 replacements
LEDs can be more than 40 percent more efficient than T8 lamps, provide a more even light distribution, are dimmable, and last years longer.
Freezer cases
When you replace fluorescent lighting in vertical and horizontal freezer cases with LED options, you can save up to 50 percent in energy costs. Plus the LEDs can be tied to occupancy sensors so they are only illuminated when customers are present.
Track lighting
You'll save big on both energy and maintenance when you install LED track lighting. Because the light from LEDs has little or no ultraviolet or infrared radiation, produce, meat and fish have longer shelf life.
Outdoor lighting
Since they are low maintenance and use less energy, outdoor LEDs reduce operating costs. Plus improved optical performance enhances the safety and security of your outdoor areas.
"Duke has been a valuable partner to help us meet our energy goals in this part of the U.S., and we've been able to share those energy-saving ideas throughout the ALDI grocery chain."

More energy efficiency incentives

Is your store already up and running with LED lighting? Let us help you continue your energy efficiency upgrades.
We offer incentives for:

Heat-recovery systems
Heat-recovery systems are available that capture waste heat from refrigerators to make hot water for use in the store. A 7.5-horsepower compressor can heat all of the hot water a midsize supermarket would use in its kitchen cleanup and bathroom sinks. Often, enough waste heat is also available to supply hot water coils for space heating in cold weather.
Display case shields
Aluminum display case shields can reduce refrigeration load from the display case by 8 percent when applied overnight and by 40 percent 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.
Evaporator-fan motors
Replacing existing shaded pole motors on evaporator fans with electrically commutated motors will reduce the energy consumption of refrigerator and freezer cases by 40 to 70 percent. Drop-in replacement designs have made this retrofit relatively simple for a technician to perform. Additionally, most evaporator-fan motors in walk-ins run continuously even though full airflow is usually required only about half the time. Consider introducing advanced controls that slow the fans when full-speed operation is unnecessary. Annual cost savings can result in about a one-year payback for the total cost.
Anti-sweat heaters
The latest anti-sweat heater controls sense humidity in the store's ambient air and reduce the operation of their heaters in low-humidity conditions. They promise significant savings and quick payback, and they are relatively easy to install.
ENERGY STAR® food service equipment
Investing in high-efficiency food service equipment can help cut energy costs by 10 to 30 percent, offering a real boost to your bottom line. In addition, it can improve the quality of food prepared, increase productivity and contribute to a cleaner environment.
Variable frequency drives
HVAC and kitchen hood motors are sized for design or maximum load. Unfortunately, your store does not require these maximum outputs all the time. A variable frequency drive (VFD) controls the speed and torque of the motor based on need. The energy saving benefits are multiplied as a result of fan affinity laws. At 63 percent of maximum motor speed, you use only 25 percent of the power you would at full speed. VFDs can also lead to extended equipment life due to less stress on components.
