Cool Keeper Frequently Asked Questions

How does Cool Keeper work?

When you enroll in Cool Keeper, we'll connect a device next to your exterior central air conditioning unit. On a few selected days during May through September, we'll automatically coordinate participating air conditioners to help ease the demand for electricity. There is no charge for signing up and installation of the Cool Keeper device is free.

What is a Cool Keeper device?

The Cool Keeper device is connected to your exterior air conditioning unit. On hot summer afternoons when electricity demand soars, the device receives a signal from Rocky Mountain Power to turn your air conditioning compressor off for short periods coordinating your AC with others in the neighborhood to help manage electricity use. Your AC will still operate when the Cool Keeper device is activated, but just about half as much. You stay cool and comfortable as the fan portion of the air conditioner continues to move cool air throughout your home. When electricity demand is reduced, the Cool Keeper device shuts down and your AC unit returns to its standard operation.

When can the program be activated?

Rocky Mountain Power can dispatch Cool Keeper events according to the following criteria:

  • Dispatch period: May 1 through September 30
  • Available dispatch hours: 2 p.m. to 9 p.m.
  • Maximum dispatch hours: 100 hours per year
  • Dispatch days: Monday through Friday, excluding holidays
  • Dispatch duration: Events will be limited to four hours per day

In the event of a system emergency, Rocky Mountain Power may, at its discretion, expand the dispatch criteria beyond the parameters listed.

Will I notice any changes in my home's temperature?

The air conditioning fan continues to circulate the cool air in your home. Most customers don't notice the typical temperature change of approximately 1 to 4 degrees. More than 92,000 customers are currently participating in the program, and 98 percent of Cool Keeper participants are satisfied with the program.

What if for some reason I don't want my Cool Keeper device to be activated on a particular day?

If you would like to make sure we don’t activate the Cool Keeper program for your home for a particular event or date, please call us at 1-800-357-9214 and you can “opt out” for the day.

Participants in the program are allowed to opt out twice each summer season. Be aware that if you opt out more than twice, you will be unenrolled and will not receive future bill credits.

Who is eligible to participate?

Cool Keeper is available to Utah Rocky Mountain Power residential and business customers along the Wasatch Front with electric central air conditioning. To verify program eligibility and to sign up for the program, call 1-800-357-9214.

Generally the control area is within the following geographic boundaries:

  • West - East side of the Oquirrh mountain range and Tooele
  • East - West side of the Wasatch mountain range
  • South - Elberta, Utah north (including Elberta)
  • North - Pleasant View, Utah south (including Pleasant View)
What cooling equipment qualifies?

Participants should have a Level 1 or 2 central air conditioner unit (Level 1 Air Conditioner: equal to or less than 5 tons, Level 2 Air Conditioner: greater than 5 tons). Qualifying equipment must comply with National Electric Code (NEC) standards. Any equipment deemed unsafe will not be allowed to participate.

Is the device compatible with my A/C unit?

Yes, the device is compatible with most AC equipment. The Cool Keeper team has been provided installation guides from Air Conditioner manufacturers to ensure the installation is done according to manufacturer standards. Only customers with A/C units that are compatible with the devices will be enrolled in the Cool Keeper program.  

Do I need to enroll all my air conditioners in the program?

Yes, all qualifying units used for cooling must be equipped with active Cool Keeper devices and available to respond to program dispatch events. Participants will receive a monthly bill credit for each device installed on qualified equipment.

Do I need to be home when the device is installed?

The device will be installed near your outside air conditioning unit, so it is not necessary for you to be home at the time. Just be sure your outdoor air conditioning unit and electrical box are accessible to our technicians. Upon completion of the installation, the service technician will leave a door hanger letting you know that the Cool Keeper device has been installed.

Will the Cool Keeper program save me money on my bill?

Yes, you will see a monthly Cool Keeper bill credit from May through September as long as you are participating in Cool Keeper. Additionally over the long term, Cool Keeper keeps costs down for everyone by more effectively managing electricity demand during Utah’s hot summer months. Programs like Cool Keeper help reduce or delay the need to build additional power plants in the future, which also helps to keep prices lower and benefits the environment.

How does the monthly bill credit work?

Residential customers who participate will receive a monthly credit totaling $30 each year. The  thank-you credit will be provided on their Rocky Mountain Power bill  during May through September billing cycles. A partial credit is applied when enrollment begins after the start of the cooling season (May 1). Participants who enroll after October 1 will receive the full $30 credit in the following year.

How often does Cool Keper cycle my unit?

In 2018 and 2017, Cool Keeper was only activated for less than 2 hours each year!

Can I cancel?

While more than 98 percent of program participants are satisfied, if you become dissatisfied, you can ask to leave the program at no cost. However, you will no longer be eligible to receive the annual $30 bill credit. If you cancel in the first season prior to September 30, you will not be eligible for the credit. Please call our program representatives at 1-800-357-9214.

I am a renter, can I participate?

Yes, if your landlord gives approval. If your apartment complex is not already participating, your landlord must submit a landlord approval form prior to device installations. If your landlord has already submitted a landlord approval form and your air conditioner already has a device installed, then you will be automatically enrolled in the program.

The owner or property manager of a participating apartment complex will provide new tenants with relevant program information. In advance of the summer season each year, Rocky Mountain Power or its contractor will provide notification to participants in cases where the unit has been enrolled in the program by the owner or property manager. Tenants may cancel their participation in the program at any time.

My apartment complex participates in the Cool Keeper program, can I opt-out of participation?

Yes. If you live in an apartment complex where the landlord has allowed participation, you can opt-out anytime by calling 1-800-357-9214.
