For the month of August 2022:
Base energy charge: $0.07412 per kWhr
Fuel charge: + $0.04855 per kWhr
Effective energy rate you pay (Base plus Fuel): $0.12267 per kWhr
Availability charge: $16.06 per month*
An average AUB residential customer uses about 1,250 kWhrs of electricity per month. Under our present residential rate, a customer's monthly bill for 1,250 kWhrs would be $169.40= (0.12267 X 1,250) + $16.06.
Understanding Your Rate
Your monthly power bill has two parts:
- An Availability Charge; and
- An energy usage charge, per kWhr consumed.
*The Availability Charge is $16.06. It applies to every bill. It pays for the fixed cost of your utility system all over the territory, i.e., what it costs to keep the system going even if no one were to use a single kilowatt hour of power. It allows us to properly maintain, service and insure the 500-plus miles of mulitphase power distribution lines, thousands of service lines and transformers, and all of the associated substations and equipment in the AUB power system. Properly recovering these costs through this charge helps us keep your monthly energy use charge as low as we can in the market. For a detailed explanation of the Availability Charge, click here.
AUB buys all of its power from TVA. TVA dictates what type rate schedules AUB can offer and uses a Seasonal Rate Schedule that has different base rate levels depending on the season.
Base rates by season:
- Summer Season: June-September = $0.07412 per kWhr
- Winter Season: December-March = $0.07088 per kWhr
- Transition Seasons: April/May & Oct/Nov = $0.06917 per kWhr
You may notice a class code on your AUB bill. Residential customers are classified as Code 1, 22, or 23, and all pay the same rate. Class code 1 is for non-urban residential service; class 22 is for urban residential service; and class 23 is for other types of residential service.
Energy use charge: What is a kilowatt hour (kWhr)?
You probably know that you get billed for your monthly usage of kilowatt hours of electricity. So what is kilowatt, and what is a kilowatt hour?
Electricity is measured in units of power called watts. Because a single watt is such a small unit of measurement, electricity use is typically tallied in 1000-watt units, called kilowatts.
Common devices such as light bulbs list a wattage rating that tells you how much energy is required for the device to operate. The higher the rating, the more electricity the thing will use. By taking the number of watts the device uses and multiplying it by the hours the device is "on" and in use you get kilowatt hours, or kWhr.
For example, burn a 100-watt light bulb for 10 hours and you will use one kWhr. (100 watts X 10 hours = 1 kWh). To see it in a different light, one kWhr also is needed to burn ten 100-watt light bulbs for one hour. (10 lights @ 100 watts = 1000 watts. 1000 watts X 1 hour = 1 kWhr.)
