What is a Cool Keeper device?
Cool Keeper is a device that is connected to your outdoor air conditioning unit. This device allows Rocky Mountain Power to turn your air conditioning compressor off for a few minutes each half-hour during selected weekday summer afternoons. This can help reduce strain on the power system.

How does Cool Keeper work?
When you enroll in Cool Keeper, we'll install a device next to your exterior central air conditioning unit. On selected weekdays during the summer, June through August, we'll automatically coordinate participating air conditioners to balance the supply and demand for electricity. When Cool Keeper is activated, your central air conditioning unit's compressor will run for a few minutes less each half-hour. Your cool air will continue to circulate so you stay comfortable. There is no charge for signing up and installation of the Cool Keeper device is free.

How often will the Cool Keeper device be activated?
Cool Keeper typically turns your air conditioner's compressor off for only a few minutes per half-hour from 2 p.m. to 8 p.m. on selected summer weekdays, and never operates on holidays or weekends.

Will Cool Keeper affect my comfort level when activated?
Most customers report they don't even notice the typical temperature change of 1 to 3°F.

Who is eligible to participate in Cool Keeper?
Cool Keeper is available to residents and small businesses along the Wasatch Front who have electric central air conditioning.

How does Cool Keeper benefit me?
By helping to keep our power infrastructure viable, Cool Keeper lessens the strain on our electric grid. This reduces the possible need to build new power infrastructure that includes a mix of fossil fuel-based generation and other resources. Plus, balancing the demand for electricity helps keep costs down by reducing the need to produce or purchase expensive peak power. In addition, as a thank you, we will give you a $40 credit* on your fall Rocky Mountain Power bill.

How does the annual bill credit work?
Customers who participate will receive the annual $40 credit* on their Rocky Mountain Power bill each fall. A partial credit is applied for participation after the start of the cooling season (June 1) as follows: Before July 1, the bill credit is $30; before August 1, the bill credit is $20; and before September 1, the bill credit is $10. Participants who enroll after September 1 will receive their bill credit the following year.

Do I need to be present when the device is installed?
You do not need to be present when the device is installed near your air conditioning unit. Just be sure your outdoor air conditioning unit and electrical safety box are accessible to our technicians.

If I am not satisfied, can I cancel my participation?
Yes. If you are ever dissatisfied, upon request you can leave the program at any time, at no cost to you. Ninety-eight percent of program participants report they are satisfied with the program.
