According to the Department of Energy's Commercial Buildings Energy Consumption Survey, the average restaurant in the US is 5,800 square feet, and uses 43.5 kWh per square foot. The average commercial electricity rate in the US is 11.33 cents per kWh (EIA November 2021). That makes the average monthly electricity bill for a full service, 5,800 square foot restaurant around $28,585 a month. Restaurants can reduce their electricity bill through energy efficiency, peak demand management and, in deregulated markets, shopping for electricity rates.
