What is the Average Restaurant Electricity Bill in 2025?

When it comes to restaurant utility costs, electricity is usually the biggest one. According to the most recent data from the Energy Information Administration (EIA), the average food service building uses 43.8 kWh of electricity per square foot per year, with electricity accounting for 58.5% of total energy consumption.

With an average building size of 4,800 square feet, that adds up to more than 210,000 kilowatt-hours (kWh) annually—translating to an estimated $2,280 per month on electricity alone, based on average national rates.

But electricity costs aren’t one-size-fits-all. Factors like restaurant type, equipment, location, and operating hours all influence your monthly expenses. In this guide, we’ll break down what contributes to your restaurant electricity bill, how different types of food service businesses compare, and what you can do to reduce your energy bill.

Key takeaways

• Electricity is often the largest monthly utility expense for restaurants, driven by energy-intensive equipment and long operating hours.

• Your location, building layout, and equipment age all play a major role in determining your electricity bill.

• Fast food restaurants use more electricity per square foot than other food service types due to compact, high-output kitchens.

• Seasonal weather swings and peak usage times can cause large fluctuations in your monthly electricity costs.

• Small upgrades—like LED lighting, smart scheduling, and ENERGY STAR appliances—can lead to significant long-term savings.

What contributes to your restaurant electricity bill?

Electricity is one of the biggest operating expenses for restaurants—especially in high-demand kitchens. From appliances to ambient lighting, dozens of daily decisions impact your monthly utility bill. Here are the biggest contributors:

• Location: Electricity rates vary widely. In New England, the average is around $0.23 per kWh, compared to just $0.09 per kWh in West South Central U.S.

• Kitchen equipment: Ovens, fryers, refrigerators, and dishwashers consume significant power.

• HVAC systems: Heating and cooling account for a major portion of electricity use.

• Lighting: Dining ambiance, signage, and back-of-house lighting add up.

• Operating hours: The longer you're open, the higher your consumption.

• Appliance age and efficiency: Older, inefficient appliances can quietly drain hundreds of dollars a month.

• Building size and layout: Bigger dining rooms, poor insulation, or inefficient setups all require more energy to operate comfortably.

• Seasonal spikes: Energy use often surges in summer (A/C) and winter (heating).

  • Example: Poor Red’s Bar-B-Q reported their PG&E bill jumped from an average of $4,000 to $5,000 during a summer heat wave. These seasonal swings can cause major surprises on your utility statement.

Average electricity bill by type of restaurant

Across the food service industry, EIA reports that electricity use totals more than 61 trillion BTUs per year in the U.S. alone. But not all restaurants consume energy the same way. Factors like kitchen layout, menu type, cooking methods, and square footage all play a role in shaping a restaurant’s monthly bill.

Fast food

Fast food establishments use the most electricity per square foot of any food service type. While they typically occupy smaller spaces than full-service restaurants, they rely heavily on dense, high-powered kitchen equipment like fryers, conveyor toasters, rapid-cook ovens, and illuminated signage. That compact, high-output setup drives up energy intensity.

• Annual electricity usage: 62.8 kWh per square foot

• Average size: 4,100 sq ft

• Estimated annual usage: ~257,480 kWh

• Electricity as % of total energy: 82%

At an average electricity rate of $0.13 per kWh, a fast food restaurant could see electric bills in the range of $2,800 per month or more—especially if operating long hours. To offset those high costs, some fast food chains are exploring more efficient ways to power their operations. As Kirk Edelman, CEO of SolMicroGrid, explains:

“By integrating sustainable, distributed energy resources at the local level, we’re helping Wendy’s reduce energy costs at its restaurants. This is just the beginning of what’s possible as we work together to redefine how businesses efficiently power their facilities.”

From renewable energy solutions to high-efficiency appliances, these investments can significantly lower long-term operating costs while supporting broader sustainability goals.

Restaurant/cafeteria

Full-service restaurants and cafeterias use less electricity per square foot than fast food spots, but they’re often larger spaces with dining areas, ambient lighting, and a mix of front- and back-of-house equipment. These venues also tend to have longer dwell times per customer and use more natural gas for cooking, which lowers their electricity share of total energy.

• Annual electricity usage: 40.6 kWh per sq ft

• Average size: 5,300 sq ft

• Estimated annual usage: ~215,180 kWh

• Electricity as % of total energy: 52.6%

At a national average electricity rate, a typical restaurant or cafeteria might pay around $2,300 per month in electricity bills.

Other food service (e.g., coffee shops, snack bars)

This category includes bakeries, food trucks, caterers, and similar operations that don’t fit neatly into the fast food or restaurant models. These businesses often operate in smaller spaces with specialized equipment like mixers, convection ovens, or warming units—resulting in lower, but still meaningful, energy demands.

• Annual electricity usage: 29.0 kWh per sq ft

• Average size: 4,100 sq ft

• Estimated annual usage: ~118,900 kWh

• Electricity as % of total energy use: 42.4%

At $0.13 per kWh, the average electricity cost for these operations comes out to about $1,290 per month. Because many of these businesses have fluctuating or part-time hours, actual usage may vary significantly.

7 tips for reducing your restaurant electricity bill

High energy costs aren’t inevitable—small upgrades and smarter habits can lead to major savings over time. Here are some of the most effective ways to lower your electricity bill without compromising service:

1. Upgrade to energy-efficient equipment: Look for ENERGY STAR–rated appliances, especially for refrigeration, cooking, and dishwashing.

2. Switch to LED lighting: LEDs use up to 75% less energy and last much longer than traditional bulbs.

3. Optimize your HVAC system: Schedule regular maintenance, clean filters, and consider programmable thermostats to reduce waste.

4. Use smart kitchen scheduling: Stagger equipment startup times to avoid peak load charges, and shut down unused appliances during slow hours.

5. Seal and insulate: Keep conditioned air in and outdoor air out with weather stripping, door sweeps, and proper insulation.

6. Train your staff: Simple habits—like turning off lights and equipment when not in use—can cut costs over time.

7. Monitor your energy use: Install submeters or use smart energy tools to track spikes, identify waste, and make data-driven decisions.

Don’t get shocked by a high restaurant electricity bill

Electricity isn’t just a background expense—it’s one of your most important monthly variables to monitor and manage. Whether you're running a fast-paced burger joint or a cozy full-service bistro, your utility bill reflects daily operational choices across equipment, scheduling, and infrastructure. 

By understanding your usage patterns and taking targeted steps to improve efficiency, you can lower overhead, boost profitability, and future-proof your business against rising energy costs.
