What is KUB's Time of Use Pilot Program?

As KUB’s Meter Modernization project has come to a close, KUB and customers across our service territory have access to more usage data, which provides a better understanding of individual energy use patterns. One benefit of this data is the ability to offer customers Time of Use (TOU) rates, a rate structure commonly used nationwide.

Since KUB has not offered them before, Time of Use rates are available on a limited basis for customers who are interested.

What are Time of Use electric rates?

The energy we use does not cost the same to generate at all times of the day. When demand is high, the cost of energy is higher. This is because more costly and often, less efficient sources are used to generate enough electricity to meet demand.

Time of Use electric rates reflect this difference. On-peak is when the rates are the highest, and off-peak when they are the lowest. Eighty-three percent of time is categorized as off-peak.

What are the rates/times?

Time of Use Rates

KUB's off-peak rate is appoximately one-third of the on-peak rate. Click here for the current rates.

On-Peak Times

  • Summer (April-Oct.): 8 p.m.-2 p.m. Monday-Friday
  • Winter (Nov.-March): 11 a.m.-5 a.m. Monday-Friday

Off-Peak Times

  • All hours not listed as on-peak above Monday-Friday
  • Weekends
  • New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, & Christmas Day

How do Time of Use rates compare to my current electric rate?

How can someone save on their bill under these rates?

For people who naturally use more energy at off-peak times, they will not have to change any behaviors in order to save. For others, they will need to make deliberate choices to shift their electric-consuming activities to the off-peak time frame.

For example, to run your average clothes dryer that uses 3,000 watts for one hour costs approximately $0.60 during on-peak time or $0.20 during off-peak time. This means if you dried one load of laundry for one hour each week, you would save $19.20 per year. (Also reflected in the chart below.)

On-peak

Off-peak

$0.60/week

$0.20/week

$2.40/month

$.80/month

$28.80/year

$9.60/year

If you do multiple loads of laundry each week, this could add up to significant savings. (Check out this laundry usage calculator.) It's important to remember that this is only taking into consideration the laundry portion of energy use. Since the largest portion of a customer’s energy consumption is heating and cooling their home, modifying behavior here will have the biggest impact.

The key with TOU rates is in when you chose to do tasks that consume significant portions of energy. An easy change could be to save all laundry, or other energy-consuming chores, for the weekends, which are always off-peak pricing. Another change could be adjusting the thermostat based on the season so you consume less energy (up in the summer and down in the winter). Customers may choose to pre-heat or cool their home during the off-peak time frame, and dial their thermostat back during on-peak.

How does someone know their daily usage?

One way to see this is to log in to your advanced meter portal and view your usage report. Through the portal, you can see usage broken down in hourly increments and will see peaks in the bar graphs when usage is the highest. Think back to your activities at that time and consider if there are things you can do at an off-peak time.

If you are not sure how to access your usage information, call KUB at 865-524-2911 to talk with a Customer Service Representative who can assist you.

Who would benefit from TOU rates?

Customers who already have behavior patterns where they are using most of their energy during off-peak time frames, along with customers who have the desire to change when they complete energy consuming tasks in order to take advantage of the lower energy rate, will benefit. Off-peak hours account for 83 percent of the hours in the week, and the weekends are always off-peak, so customers who are able to make conscious decisions about their tasks will benefit.

Other types of customers who might benefit include:

  • Customers with at-home electric vehicle charging stations with a timer to charge only during off-peak hours
  • Customers with smart thermostat devices in their home. These can be programmed to increase or decrease the thermostat setting coinciding with the on and off-peak time frames.
  • Customers with solar arrays that can provide energy during daytime on-peak hours and/or can store energy for nighttime on-peak hours.

How do I sign up for Time of Use Rates?

If you think you could benefit from participating KUB’s Time of Use Pilot Program, call 865-588-4177 Monday-Friday 8 a.m.-5 p.m. to speak to a Customer Service Representative.

If I sign up, can I decide to return to my previous rates structure?

Yes. If you enroll in KUB’s Time of Use Pilot Program, you may unroll one time per year. You will not be able to re-enroll in the program for 12 months after your unenrollment date.

Are there any other ways I can save energy and/or money on my bill? 

Yes, there are various changes you can make in your home that could save energy and money. Click here for a list of tips.
