Keep your cool - and your cash!
When Midwestern summers bring 90 degree temperatures and high humidity levels, the huge demand for electricity puts a big strain on the energy system. With Alliant Energy's Appliance Cycling program, you can help us meet electricity needs during peak demand times.
Not only will you reduce your energy costs, we’ll compensate you for participating in the program. The amount of credit depends on the program option you sign up for.
How does Appliance Cycling work?
When you sign up for the program, we'll send a contractor to install a small, radio-activated control switch on or near your outdoor central air conditioner at no cost to you.
If the demand for electricity escalates to a critical point, a "system emergency" or "peak alert" is announced, and we'll turn on the radio signal that activates the switch on your air conditioner. The receiver will be activated to cycle the outdoor cooling unit according to the program option you elected.
The switch will cycle your air conditioner, while the furnace fan continues to circulate the cooler, drier air already in your home. You'll stay cool and comfortable, your electric bill stays low and the environment can breathe a little easier.
The program runs from May to September but dates vary in each state. Cycling events typically occur Monday through Friday from 1 p.m. to 7 p.m. and never on weekends or holidays.
Do I qualify?
This program is available to all Iowa residential Alliant Energy electric customers that meet the following criteria:
- You must own your home, have a central air conditioner and receive retail electric service from Alliant Energy.
- Installation is only allowed at your primary residence.
- Participation is limited — control receivers will be distributed on a first-come, first-served basis.
How do I sign up?
Once you sign up, you will automatically receive the savings each summer. No need to sign up every year.
Your outdoor unit will turn on and off when your air conditioner is cycling. However, your furnace fan will continue to operate as long as the thermostat fan switch is in the “auto” or “on” position and the thermostat calls for cooling.
Temperature and humidity levels may increase slightly but not enough to make a noticeable difference.
A red light indicates the switch has received a signal to cycle. Also, if power to the switch has been interrupted – such as a breaker being shut off and turned back on – the red light will come on and go back off within five minutes. This is a safety precaution that all the switches have.
A green light (solid or blinking) should be on all the time and is a communication light. This light will not affect the air conditioner’s ability to run or cool.
Central air conditioners will be cycled every 15 minutes on and off in Iowa. Wisconsin offers three different cycling options at 50%, 75% and 100%. Cycling will take place no longer than six hours in one day. Cycling typically occurs 1 to 7 p.m. Monday through Friday and never on weekends or holidays. Your furnace fan; however, will continue to operate as long as the thermostat fan switch is in the “auto” or “on” position and the thermostat is calling for cooling.
Water heaters are shut off during the entire control period, not to exceed six hours per day.
