Asked Questions

AC Peak Cycling device is installed on your home near your outside air conditioning unit. During a limited number of peak demand periods, Consumers Energy will activate the small device, which will allow Consumers Energy to reduce your unit’s cycling run time by 50%. This is referred to as a “cycling event.” During cycling events, your air conditioning system’s fan will continue to circulate air throughout your home. After the period of peak demand has passed, the AC Peak Cycling device will trigger your system to automatically resume normal operation.

“Peak demand” refers to periods of exceptionally high energy demand. These periods typically occur during the summer months, when air conditioning use increases significantly. Using energy wisely during times of peak demand reduces stress on the electric grid and makes the electricity delivery system more reliable.

Cycling events will typically occur on non-holiday weekdays between noon and 8 p.m., but events could occur at any time in the case of an electric emergency. These events will take place from June through September and typically will last between 4 and 8 hours.

Program participants may opt out of one AC Peak Cycling event per year by calling 877-789-9883. Opt-outs may be scheduled in advance and will only be counted if an event has taken place on that date.

Most customers report minimal changes in temperature. Potential temperature change during cycling events depends on a variety of factors, including the temperature outside and the home’s insulation.

Electricity costs increase during periods of peak demand, and local or regional capacity challenges can also occur when central air conditioning use is at its highest. AC Peak Cycling is a way that our customers can voluntarily assist with keeping electricity reliable and affordable for all. Reducing electricity use during peak periods offsets the need to purchase and generate additional electricity.
