Top 10 Restaurant Equipment That Uses Most Electricity

Running a restaurant requires various types of equipment, many of which consume significant amounts of electricity. Understanding what uses most energy in a restaurant can help you manage costs and optimize energy usage. In this article, we will discuss the top 10 restaurant equipment that uses the most electricity.

1. Refrigerators and Freezers

Refrigerators and freezers are essential for keeping food fresh and safe. However, they run continuously, making them one of the largest energy consumers in any restaurant. Modern commercial refrigeration units are designed for efficiency, but they still require substantial power to maintain the necessary temperatures.


  • Walk-in Freezers: These large units can consume up to 11,000 kWh annually.

2. Ovens

Ovens, especially commercial-grade models, use a lot of electricity to reach and maintain high cooking temperatures. Whether it’s a convection oven, a combination oven, or a pizza oven, these appliances are critical but energy-intensive.


3. Dishwashers

Commercial dishwashers are designed to clean large quantities of dishes quickly. They require substantial amounts of water and electricity, especially high-temperature models that use hot water for sanitation.

4. Ice Machines

Ice machines are a constant source of energy consumption in restaurants, particularly in establishments that serve beverages. These machines must continually produce and store ice, which requires a lot of electricity.


  • Large Ice Machines: Can use up to 3,400 kWh per year.

5. Griddles and Grills

Electric griddles and grills are popular in many kitchens for their versatility in cooking different types of food. They need to maintain high temperatures, resulting in significant energy use.


6. Fryers

Commercial fryers, used to prepare a variety of fried foods, require a lot of power to heat oil quickly and maintain the cooking temperature.

7. Heating, Ventilation, and Air Conditioning (HVAC)

HVAC systems are crucial for maintaining a comfortable environment for both staff and customers. They are one of the largest energy users in a restaurant, especially in extreme weather conditions.


8. Coffee Machines

High-end coffee machines, especially those used in coffee shops or restaurants with a significant coffee service, consume a lot of electricity due to their heating elements and continuous use.


  • Espresso Machines: These can use between 1,000 to 1,500 watts per hour.

9. Blenders and Mixers

Blenders and mixers, used in both food preparation and beverage services, require considerable power, particularly when used frequently.


10. Microwaves

Commercial microwaves are designed for quick and efficient heating, but this comes with high energy consumption, especially during peak hours.
